考研英语十二大基础语法体系
对于任何英语句子，要分析其结构，这样才能找到英语语言的规律。 每种语言都有它的难点，汉语的难点在于汉语不是拼读语言，汉字很难写，而且有四种声调。其实，许多接触过多种外语的人都认为，英语的语法比法语、德语、俄语、日语等都简单，是最容易学的。著名语言学家乔姆斯基说过，语法是内生的、也就是随着语言的诞生而诞生的。因此，学习语法和学习语言是相辅相成的。 一、 英语动词的时态
（一）英汉两种语言在时态表达方式上的差异：
英语的词类与汉语的不同。汉语词类形态稳定，比如“书”这个字，“一本书”、“三本书”都一样，没有词形变化。英语就不同了，book, books仅从词形上就能知道是单数还是复数。
动词是英语中变化最多、最复杂的词类。有人说，学好英语就是学好动词，此言甚是。同一个动作或状态分别在不同时间发生或存在，表达这个动作或状态的动词就要用不同的形式，这就是时态。 （二）英语动词的形式：
英语的时态是通过动词的变化来体现的。因此，了解动词的形式及其变化规律非常重要。英语的实义动词有以下五种形式：
(1) 动词原形：动词原形在句子中形式不变。主要用于主语为非第三人称单数的一般现在时，情态动词之后，
或根据语法规定必须用动词原形的其他情况。
(2) 一般现在时第三人称单数形式（简称现单三）：主要用于主语为第三人称单数的一般现在时。 (3) 过去式：主要用于一般过去时。
(4) 现在分词：主要用于进行时态，或语法规定的其他情况。 (5) 过去分词：主要用于完成时态，或语法规定的其他情况。 动词一般现在时第三人称单数（现单三）的构成，见下表： 词尾变化（规律与名词变复数相同，读音也与名词复数相同） 一般加-s 在ch, sh, s, x 或元音字母o后面加-es 以辅音字母加y结尾的词，变y为i再加-es 与名词变复数形式相同，读音也相同。 动词过去式和过去分词，大多数是动词原形+ ed 构成，这是规则动词。规则动词的拼写和读音规则如下表： 词尾变化 举例 Help---helped Work---worked 动词后面加-ed Watch---watched Want---wanted need---needed Turn---turned play--played 以不发音的“e”结尾的词，加-d Love---loved 词尾读音 清辅音之后读[t] [t] ,[d]之后读[t] 元音和浊辅音（[d]除外）之后读[d] 举例 Help---helps; read---reads Do, fix, pass, push, teach ---does, fixes, passes, pushes, teaches Try, study --- tries, stuides 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
Serve---served 结尾是辅音字母+y时，y变i，再加-ed 结尾只有一个辅音字母的重读闭音节词，双写辅音字母再加-ed Study---studied Try---tried Stop---stopped Drop---dropped 清辅音之后读[t] 不规则动词的过去式和过去分词有其特殊变化形式，需要个别记忆，同时也要善于发现不规则中的规则，即某些字母组合的不规则动词有一定的规律。如：weep→wept, sleep→slept, sweep→swept 现在分词一律由动词原形加-ing构成，规则如下表： 词尾变化 一般加-ing 以不发音的e结尾的词，去掉e，再加-ing 先双写词尾的辅音字母，再加-ing 以-ie结尾的词，变ie为y，再加-ing 举例 Look---looking, try---trying Write---writing, dance---dancing Run---running, sit---sitting Die---dying, lie---lying 以一个辅音字母（x除外）词尾的重读闭音节词，Begin---beginning, swim---swimming, 为了学习的方便，人们把时间分为四个阶段：“现在、过去、将来、过去将来”。英语动词所表示的动作在以上每个时间段中分别有四种状态：一般、进行、完成和完成进行。因此我们便有了四四一十六个时态。 不同的时态有不同的变化形式。以do 为例，列表如下： 时态 一般 进行 完成 完成进行 Has/have+been doing Had been doing been doing + Would/should + have been doing 现在时 Does; do 过去时 Did 将来时 Shall/will+do 过去将来时 Should/would/+do Am/is/are+doing Has/have+done Was/were+doing Had done Shall/will +doing doing done have done be Shall/will have + Shall/will+have Would/should+be Should/would “时态”就是通过动词的形态变化，来表达动作发生的时间（现在、过去、将来、过去将来）及所处的状态（一般、进行、完成、完成进行）。
比如在“They are doing their exercises.”这个句子中，动词由原形do 变成are doing 的形态，说明这个事情是发生在现在、并处于正在进行的状态当中，所以叫现在进行时；
在“They have done their exercises.”这句中，动词由原形do 变成have done的形态，说明这个事情是发生在现在、并处于完成的状态，所以叫现在完成时；
在“They always do their exercises.”中，动词用原形do 的形态，说明这个事情是发生在现在、并且是一般情况下永远如此，所以叫一般现在时。
在这三句话中，动词do 虽然用了不同的形态，其意义没有变化，而是事情发生的时间和状态变了。其余类推。 （三）时态详解
16个时态中，常用的有12个：一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时、现在完成进行时和过去完成进行时。其他时态很少单独使用。

下面把各种时态的构成和用法做一个全面的介绍。 1、一般现在时
动词be和have(表示“拥有”)各人称的单数形式为： Have Be 第一人称单数 Have Am 第二人称单数 Have Are 第三人称单数 Has is
通常以动词原形表示。主语为第三人称单数时，用现单三形式。
一般现在时的否定式、疑问式和简单回答形式如下： 动词be 与 have（表示“拥有”）：否定式直接把not放在动词之后，疑问式直接把动词放在主语之前，见下表： 否定式 Be I am not (I’m not)… You are not (aren’t)… He is not (isn’t)… 否定疑问式 Am I not (aren’t i)…? Are you not (aren’t you)…? Is he not (isn’t he)…? 下表： 否定式 Be I am not (I’m not)… You are not (aren’t)… He is not (isn’t)… 否定疑问式 Have I not (haven’t i)…? Has he not (hasn’t he)…? Have You have not (haven’t)… 疑问式 Be Have Have I …? Have you…? Has he …? 否定回答 No, you haven’t. No, I haven’t. No, he hasn’t. I have not (haven’t)… Am i…? Are you …? Have You have not (haven’t)… 疑问式 Be Have Have i…? Have you…? Has he …? 否定回答 No, you aren’t No, I’m not. No, he isn’t I have not (haven’t)… Am i…? Are you…? He has not (hasn’t)… Is he …? 肯定回答 Yes, you are. Yes, I am. Yes, he is. 动词be 的否定疑问式和简单回答： 动词be 与 have(表示“拥有”)：否定式直接把not放在动词之后，疑问式直接把动词放在主语之前，见He has not (hasn’t)… Is he …? 肯定回答 Yes, you have. Yes, he has. 动词have(表示“拥有”) 的否定疑问式和简单回答： Have you not (haven’t you)…? Yes, I have. 注意：have 作为行为动词则只能按照行为动词的规则变化。 行为动词（以study为例）一般现在时的否定式、疑问式和简单回答（注意要加助动词do/does） 否定式 疑问式 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
I do not (don’t) study You do not (don’t) study He does not (doesn’t) study 否定疑问句式 Do I not (Don’t I) study…? Do you not (Don’t you) study…? Does he not (Doesn’t he) study…? 2、现在进行时 Do I study Do you study Does he study 简单回答（肯定/否定） Yes, I do. No, I don’t. Yes, you do. No, you don’t. Yes, he does. No, he doesn’t. 由助动词be ＋ 现在分词构成。其中be有人称和数的变化，有三种形式：第一人称单数用am, 第三人称单数用is, 其他用are。
现在进行时的否定式是：直接在助动词be后面加上not；疑问式是：把助动词be提到主语之前。以study 为例： 否定式 I am not studying You are not studying, He is not studying. 5、一般过去时 一般过去时通常由动词过去式表示。一般过去时的否定式、疑问式和简单回答形式要用助动词do 的过去式did, 同时注意实义动词要用原形。以study 为例，其否定式、疑问式和简单回答形式如下： 否定式 I did not (didn’t) study…. You did not (didn’t) study…. He did not (didn’t) study…. 否定疑问式 Did I not (Didn’t I) study…? Di you not (Didn’t you) study…? Did he not (Didn’t he) study…? 6、过去进行时 由助动词be 的过去式 ＋ 现在分词构成。其中be有人称和数的变化，第一、第三人称单数用was，其他用were.
1）过去进行时动词主要表示在过去某一时刻或某一段时间内正在进行或持续进行的动作。过去进行时经常与过去时配合使用。例如：
This time yesterday, we were having an English lesson. 昨天这个时候，我们正在上英语课。 The teacher was giving us a lesson when Tom walked into the room. 老师在给我们上课时，汤姆走进教室。
简单回答 （肯定/否定） Yes, you did. No, you didn’t. Yes, I did. No, I didn’t. Yes, he did. No, he didn’t. 疑问式 Did I study…? Did you study…? Did he study…? 疑问式 Am I studying? Are you studying? Is he studying? 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
While we were having supper, all the lights went out. 我们吃饭的时候，灯灭了。 He was reading while she was setting the table. 她摆桌子时，他在读书。 It was getting dark. The wind was rising. 天渐渐黑下来了。风势增强了。
2）过去进行时动词常用always, continually, frequently 等词连用，表示过去经常发生的行为。这种用法表明带有的感情色彩。例如：
The two brothers were frequently quarreling when they were young. 两兄弟小时候常吵架。 In Qing Dynasty, China was always making concessions to western powers. 清朝时，中国总是对西方列强妥协。 7、过去完成时
一律用had + 过去分词构成。 用法：
1）表示发生在过去某一时间或动作之前的事情，即“过去的过去”。用过去完成时，必须有一个过去的时间或动作来作参照，说明在此之前某事已发生。如果两个动作都是在过去发生的，先发生的用过去完成时，后发生的用一般过去时。例如：
She told me she had been there three times before. 她告诉我她以前到过那里三次。（“去过”发生在“告诉”之前）
How long had he taught here by the end of last term? 到上学期末为止，他在这里教学多长时间啦？ （“教学”发生在上学期末结束之前）
When we arrived, the football match had already begun. 我们到的时候，足球赛已经开始了。 She had visited China twice before she came this year. 她今年来中国之前已访问过中国两次了。 2）过去完成时动词可以表示过去某一时刻之前发生的动作或呈现的状态，这一动作一直持续到过去这一时刻或将继续下去。例如：
By the middle of last month, I had lived in Beijing for five years. 到上月中旬，我已在北京住了五年了。 By six o’clock they had worked for eight hours. 到六点为止，他们已工作八小时了。
When I came to Shanghai, he had been there for a long time. 我到上海时，他在那里很长时间了。 3）过去完成时动词常用于间接引语和虚拟语气，我们以后会详细讲述。
4）此外，过去完成时常用于 no sooner…than… 和 hardly(scarcely) …when… 这两个句型，前面部分用过去完成时，后面部分用一般过去时。例如：
No sooner had he stolen the purse than he was caught red-handed. = He had no sooner stolen the purse than he was caught red-handed. 他刚偷到钱包就被当场抓获。
Saddam had hardly realized what was happening when he was captured. = Hardly had Saddam realized what was happening when he was captured. 萨达姆还没有意识到在发生什么事情就被抓获了。
8、过去完成进行时
had been + 动词的现在分词。
用法：表示一直持续到过去某个时间的行为动作，此行为动作或刚结束、或还没结束（可以从上下文看出）。这一时态经常与一般过去时一起使用。例如：
When he came in, I had been trying to repair the TV for a couple of hours. 他进来的时候，我一直
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
在努力修理电视机好几个小时了
The roads were dangerous. It had been raining for two whole days. 道路很危险。雨一直下了两整天。 They were tired because they had been digging since dawn. 他们累了，因为从天亮开始他们就一直在挖。
The boy was delighted with the new mountain bike. He had been hoping for one for a long time. 那男孩得到一辆新山地自行车很高兴。很长时间来他一直希望有一辆。 9、一般将来时
一般将来时动词表示将来发生的动作或情况。主要有以下几种表现形式： （1）shall/will + 动词原形
表示单纯的将来，不涉及主语的主观意愿。第一人称I, we用shall 或will，其余用will. 其否定式、疑问式和简单回答形式如下： 否定式 I shall/will not study…. You will not study…. He will not study…. 否定疑问式 Shall I not (shan’t i) study…? Will you not (Won’t you) study…? Will he not (Won’t he) study….? 例如： I shall be twenty years old next year. 我明年二十岁。
The sky is black. I think it will rain. 天黑下来了。我想可能会下雨。 You will meet him at the station this afternoon. 你下午会在车站碰到他。 The train will arrive soon. 火车快要到了。
When shall we see you next time? 我们下次什么时候能看见你呢？ He probably won’t go with us. 他大概不能和我们一起去。 注意：
1）shall, will的缩写形式为’ll, 如I’ll, you’ll, he’ll 和she’ll等。
2）will 用于第一人称时，可以表示将来的意愿、决心、允诺、命令等；shall用于第二、三人称时，可以表示说话人的将来的意愿。例如：
I will give you a new pen for your birthday. 我将送你一支新钢笔作为生日礼物。（允诺） I will take the college entrance examination. 我将参加大学入学考试。（决心） Shall I open the window? 我打开窗户好吗？（征求允诺）
You shall have the book as soon as I get it. 我一拿到书就给你。（说话人的允诺） The enemy shall not pass. 决不让敌人通过。（说话人的保证） I will do my best to help you. 我愿意尽力帮助你。（意愿）
Nobody shall be late for the meeting. 任何人开会都不能迟到。（说话人的命令）
简单回答（肯定/否定） Yes, you will. No, you won’t. Yes, I shall/will. No, I shan’t/won’t. Yes, he will. No, he won’t. 疑问式 Shall I study…? Will you study…? Will he study…? 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
（2）be going + 动词不定式
1）这种结构表示主体现在打算在最近或将来要做某事。这种打算往往是事先考虑好的。例如： My brother is going to learn English next year. 我哥哥准备明年学英语。 I am going to meet Tom at the station at six. 我六点钟要到火车站去接汤姆。 She is not going to be there. 她不会到那儿去的。
When are you going to finish your work? 你的工作什么时候做完？ He is going to stay a week. 他准备呆一星期。
We are going to call a meeting to discuss it. 我们准备开个会来讨论一下。 2）这种结构还可以表示说话人根据已有的迹象认为非常可能即将发生某事。例如： Look at these black clouds？it is going to rain. 看这些乌云？要下雨了。 I think it is going to snow. 我看要下雪。
I am afraid I am going to have a bad cold. 恐怕我要得重感冒。 10、将来进行时 shall/will be + 现在分词
用法：将来进行时动词表示在将来某一段时间内将会发生的动作。
This time next week we shall be working in that factory. 下星期这时候，我们将在那个工厂劳动。 When I get up tomorrow morning, my mother will be getting breakfast for me. 当我明天早晨起床时，我妈妈将在为我准备早饭。
I will be seeing him next month. 我下个月将要见他。
Tomorrow we will be going to the village fair. 我们明天去赶集。
We will be taking our holiday at the seaside in July. 七月份我们要去海边度假。
一般将来时与将来进行时都表示将来，那么如何区别一般将来时和将来进行时呢？将来进行时不表示个人意愿，强调主观上感觉某事即将发生，并对这一事情有着期待，感情色彩较浓，强调动作。一般将来时主要是对某一事情即将发生做一个事实性的说明或陈述，强调事实或意愿。 11、过去将来时
（1）由should/would + 动词原形构成。第一人称用should; 第二、三人称用would。美国英语所有人称一律用would. should/would 的简略形式为’d, 如I’d, you’d; would not 和should not的简略形式分别为wouldn’t 和shouldn’t.
（2）过去将来时表示从过去某时间看将要发生的事情，多用在宾语从句中。还可以表示过去的倾向或过去经常发生的事情。如：
They asked me if I would go to Guangzhou soon. 他们问我是否很快要去广州。 She told me she would come again next week. 她和我说她下周还来。
I told him to leave immediately, but he wouldn’t. 我告诉他马上离开，但他不。 He’d play the violin when he was in low spirits. 他情绪低落的时候，就拉小提琴。
When I was in college, I would find a part-time job during the summer holidays every year to earn my tuition. 我上大学的时候，每年暑假都找份临时工挣学费。 （3）其他表示过去将来时的结构： 12、将来完成时
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
shall/will + have + 过去分词
用法：将来完成时动词主要表示在将来的某一时刻或将来的某一时刻之前完成的动作，这一动作也可能继续进行。例如：
By seven o’clock this afternoon we shall have got to Shanghai if the train keeps good line. 如果火车运行正常，我们今天下午七点就到上海了。
Before bedtime Xiao Ming will have completed his work. 到上床睡觉的时候，小明会做完他的工作（或作业）。
By February next year this foreign expert will have been here on this job for five years. 到明年二月，这个外国专家在这儿做这项工作就满五年了。
By Sept. 2008 Beijing will have held/hosted the Olympic Games. 到2008年9月，北京将举行完了奥运会。
二、被动语态 （一）简介
在英语中，语态是动词的一种形式，表示主语和谓语的关系。英语动词有两种语态，即主动语态和被动语态。主动语态(active voice) 表示主语是动作的执行者；被动语态（passive voice）表示主语是动作的承受者。如：
Saddam is being tried. 萨达姆正在接受审判。
The Iraqi government is trying Saddam. 伊拉克政府正在审判萨达姆。 More and more people use computers now.（主动语态） Computers are more and more widely used now.（被动语态） English is spoken all over the world. (被动语态) （二）英汉两种语言在表达被动方式上的差异
汉语表达被动语态非常简单明了，用“被”“遭”“受”等词来表示，如“被捕”、“被杀”、“受到凌辱”等。而英语表达被动的方式也不复杂，用“助动词be+动词的过去分词”表示。其中助动词be有人称、数量和时态的变化，而这正是英语被动语态的难点。 （三）被动语态的构成
被动语态由“be+及物动词的过去分词”构成。这里要强调一定是及物动词的过去分词，因为不及物动词不能带宾语，也就不可能有被动语态。英语主动语态有16个时态；被动语态常用的有8个，以give为例说明如下： 时态 一般现在时 一般过去时 一般将来时 现在进行时 过去进行时 过去将来时 现在完成时 动词形式 Am/is/are given Was/were given Shall/will be given Am/is/are being given Was/were being given Should/would be given Has/have been given 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
过去完成时 never等其他否定词、句末用句号。如：
Had been given 被动语态的疑问句是将第一个助动词移到主语之前、句末用问号；否定式是在第一个助动词后加not或“During the interview, were you asked questions in English?” “No, I wasn’t asked questions in English.” “面试的时候，用英语问你问题了吗？”“没有，没有用英语问我问题。”
The origin of the universe will probably never be explained. 宇宙的起源大概永远也不会被解释清楚。 Is the restaurant being decorated? 那家餐馆正在装修吗？
The restaurant is not being decorated. In the fact the restaurant has never been decorated。 那家餐馆没有在装修。实际上，那家餐馆从来没有装修过。 （四）被动语态的用法
1、不知道或没有必要指出动作的执行者。换个说法，有一件事情不知道是谁干的或者不想说出是谁干的，这时就用被动语态。例如：
I felt a littlie nervous when I was being interviewed. 我接受面试的时候，有点紧张。 These fighters are imported from Russia. 这些战斗机是从俄国进口的。 That place has been turned into a swimming pool. 那个地方已被变成游泳池。 2、说话或发表意见时，为了显得客观公正，也常用被动语态
He’s said/believed/reported to be in the U. S. A. 据说/据信/据报道他在美国。 还有下列常用句型（that后面跟句子）： It is said that……. 据说 It is reported that……. 据报道 It is hoped that……. 希望 It is believed that……. 人们相信 It is announced that……. 据宣布 it is (well) known that……. 众所周知 It has been decided that……. 已经决定 It is supposed that……. 人们认为 It is suggested that……. 有人建议
It must be remembered that……. 务必记住 It is taken for granted that……. 被视为当然 （五）主动句变被动句的注意事项
一是时态不能改变；二是变为被动语态后，谓语动词要和被动语态的主语在人称、数上保持一致。还要作如下变动：把主动语态的宾语变为被动语态的主语；主动语态的主语放在by的后面，组成介词短语，再把这个介词短语放在被动语态的谓语动词之后。在动作的执行者无须说明或不必要强调时，by短语可以省略。例如：
They will open a new supermarket there soon. 他们很快将在那里开办个新超市。 A new supermarket will be opened there soon. 一个新超市不久将在那里开办。 The doctor gave two lectures in English. 那位医生用英语讲了两次课。
Two lectures were given by the doctor in English. 由那位医生用英语讲了两次课。

Somebody has warned us to be careful of rats. 有人警告我们要当心老鼠。 We have been warned to be careful of rats. 我们受到警告，要当心老鼠。
如果主动语态有两个宾语（直接宾语和间接宾语），变为被动语态时，可将其中任何一个宾语变为主语，另一个不变。但较常见的是将间接宾语变为被动语态的主语。
The reporters asked the president some questions. 记者们问了总统一些问题。 The president was asked some questions by the reporters. （ 变间接宾语为主语） Some questions were asked the president by the reporters. （变直接宾语为主语） We have given him a job. 我们已给了他一个工作。 He has been given a job. （变间接宾语为主语） A job has been given (to) him. （变直接宾语为主语） （六）含有情态动词的被动语态
句中含有情态动词时，其被动语态的结构是：情态动词+be+过去分词： The timetable can be changed any time. 时间表随时可以改变。
This book may not be taken out of the reading room. 这本书不允许带出阅览室。 This dictionary must be taken good care of. 这本词典必须保管好。 （七）关于被动语态的几点说明
1、有些动词形式上是主动，意义上是被动。例如: School begins in September. 学校九月份开学。
The library doesn’t open on Sunday. 图书馆星期天不开放。 The machine runs well. 这台机器容易操作。 My pen writes well. 我的钢笔好使。 The cloth washes well. 这料子耐洗。 The dictionary sells well. 这词典销路很好。 The book hardly sells. 这书买不出去。 The door will not shut/lock. 门关/锁不上。
2、make, see, watch, hear, notice, feel等使役动词和感官动词的宾语后面可以接不带to的不定式作宾补。但在被动语态中，不定式符号to必须补上。例如： They made him go. 他们让他去。 He was made to go. 他被要求去了。
I heard him say good-bye to his friends. 我听见他向他的朋友说再见。 He was heard to say good-bye to his friends. 有人听到他向他的朋友说再见。
3、除助动词be外，动词get有时也可跟过去分词构成被动语态，是比较口语化的一种被动语态。这种结构中很少用by短语。例如:
I got lost in the huge market. 在那个巨大的市场中我迷失了方向。 You might get killed/hurt. 你会送命/受伤的。
In the end this story got translated into English. 这故事最后被译成了英文。 His car got damaged in a road accident. 他的车在交通事故中被毁了。 4、“have/get+宾语+过去分词”这个句型也表达了一种被动的意思。如：
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
I’ll have the bike repaired in no time. 我一会就把自行车修好。
I had my wallet stolen/lost last Sunday when I was shopping. 上星期天买东西的时候我的钱夹被盗。 He got his leg broken when playing football. 踢足球的时候他把腿弄断了。
I bought these books at a discount and had two hundred dollars saved. 我打折买了这些书，省了两百美元。
5、在need, want, require后面，主动的-ing形式表达被动的意思： My watch needs cleaning. (=…needs to be cleaned) 我的表需要清洗。 Your garden needs watering. (=…to be watered) 你的花园需要浇水。 Does your suit require pressing, sir? 先生，您的衣服要烫吗？ 三、虚拟语气
多数中国人对虚拟语气的理解是：虚拟语气表示说话人的愿望，是假设的，虚构的，与事实相反的，或者是不太可能的。这种理解固然是对的，但并不全面。在英语中，虚拟语气是个广义的概念，包括好几种句型和结构。假设，意愿等只是虚拟语气的两个方面。 英汉两种语言表达虚拟语气的方式差异：
而在英语中，虚拟语气是通过句子中谓语动词的特殊形式来表示的。这又一次证明动词在英语中的核心地位，又一次证明要学好英语语法，就要学好英语动词。由于虚拟语气是通过句子中谓语动词的特殊形式来表示的，因此，掌握虚拟语气中所使用的各种谓语动词形式变化是掌握虚拟语气的关键，这也是虚拟语气的难点。虚拟语气本身也是英语语法的一个难点。
学习虚拟语气的方法是分别弄通虚拟语气的各种句型和结构，各个击破。下面对虚拟语气在各种句式中的用法分别介绍。
（一）虚拟语气用于表示假设的条件状语从句，状语从句相当于汉语的“假如…” “要是…”等。 请看一个句子：
If she invites me tomorrow, I shall go to the party. 如果她明天邀请我参加聚会，我就去。
这是个带条件从句的主从复合句，是直接的陈述语气，主句谓语动词用将来时，从句谓语动词用现在时代替将来时，表示能实现的动作。这句话说明说话人认为邀请的可能性较大。此句的条件是“只要她邀请我”，“去”这一动作就能实现。
请把这句话与下面虚拟语气的带条件从句的主从复合句进行比较：
1） If she invited me, I should go to the party. 假如她邀请我参加聚会，我就去。（说话人认为邀请的可能性较小或不可能。）
这句话主句谓语动词用过去将来时，从句谓语动词用一般过去时，其含义是：
She will probably not invite me, so I shall not go to the party. 她很可能不会邀请我参加聚会，所以我不会去。
2） If she had invited me yesterday, I should have gone to the party. 假如她昨天邀请我参加聚会，我就去了。
这句话主句谓语动词用“should ＋ have + 过去分词”形式，从句用过去完成时，对过去发生的事情进行虚拟假设，表示与过去 事实相反的情况，其含义是：
She didn’t invite me yesterday, so I didn’t go to the party. 她昨天没有邀请我参加聚会，因此我没
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
有去。
3） If she should invite me tomorrow, I should go to the party. 如果她明天邀请我参加聚会，我会去的。
这句话主句谓语动词用过去将来时，从句谓语动词也用过去将来时，表示的意思是，“邀请我”的可能性较小，对将来要发生的情况表示怀疑。其含义是：
It is unlikely that she will invite me tomorrow, so I shall not go to the party. 明天她不可能会邀请我，因此我不会去。
从以上例句可以看出：虚拟语气的条件句是用谓语动词的特殊形式来表示与现在、过去事实相反的情况或对将来发生的情况表示怀疑，和直陈语气条件句的谓语动词形式以及所表达的含义完全不同。虚拟语气条件句中所用的谓语动词过去式、过去完成式、过去将来式等只表示不同的虚拟语气，与直陈语气句子的过去时、过去完成时等毫无关系，在学习时应注意加以区别，不要混淆。 现将虚拟语气在条件句中的各种具体形式和用法分述如下：
1、对现在的虚拟，表示与现在事实相反的假设时，条件状语从句的谓语动词用过去式（be的过去式用were.而主句中的谓语动词用would (should, could, might) + 动词原形。见下表： 条件状语从句的动词形式 I，he，she，it等后面也可用was.但在If I were you中，一定要用were，不能用was. 2、对过去的虚拟，表示与过去的事实相反的假设时，条件状语从句的谓语动词用过去完成时,主句的谓语动词用would (should, could, might)+过去分词。见下表： 条件状语从司的动词形式 If+主语+had+过去分词 3、表示与将来事实相反的假设，对将来表示怀疑，或将来的动作不太可能实现时，条件状语从句和主句的谓语动词有以下形式：（见表） 条件状语从句的动词形式(三种) (1)if十主语+动词过去式(be的过去式用were)，通常要与一个表示将来的时间状语连用. (2)If+主语(任何人称和数)+should+动词原形 (3)if+主语(任何人称和数)+were to+动词原形 4、当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，动词的形式要根据它所表示的时间来调整。这与以上三种情况不同，虚拟语气的谓语动词形式没有遵循以上规律。
5. 以上句型可以转换成以下形式：
1）条件状语从句省略if：在书面语中，如果条件状语从句的谓语中有were, had 或should, 就可以省略
主句的动词形式 I(we)should+动词原形 主语+would (might, could)+动词原形 主句的动词形式 i(we)should+have+过去分词 主语+could (might,could)+have ＋ 过去分词 主句的动词形式 主语+would (might,could)十动词原形 If+主语+动词过去式(be的过去式were.在口语等非正式场合中，I (we)should+动词原形 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
if, 并将were, had 或should 放到句首，谓语主语之前，用 “Were/Had/Should + 主语”的形式。这种虚拟语气在意义上与带if 的条件状语从句相同。当然，如果从句没有were, had, 或should,就不能省略if.
2）用介词短语代替条件状语从句。（可以改为条件状语从句）。例如： Without air, there would be no living things. But for your help, I couldn’t have done it.
3）用其他方式代替条件状语从句（可以改写为条件状语从句。）例如：
It would produce bad results to do that. 用动词不定式 =If you did that/should do that, it would produce bad results.
6、虚拟语气省略条件从句或主句
表示虚拟语气的条件句的主句或从句有时可以省略，而省略部分的含义仍有所体现。 （二）虚拟语气的其他句型和用法
1、用在“wish+宾语从句”中，表示很难实现或不能实现的愿望，可以翻译为“但愿…”, “悔不该…”等。表示现在不能实现的愿望，从句的谓语动词用过去式；表示将来的愿望，从句的谓语动词用“would (could)+动词原形”；对过去的事情表示愿望，从句的谓语动词用 “had+过去分词” 或“could + have + 过去分词”。Wish 后面的宾语从句必须用虚拟语气，不管这个愿望是否能实现。如： I wish it were Spring all the year round. I wish you could go with us.
We wish we had arrived there two hours earlier.
2、用在as if/as though,或even if/even though引导的从句中: 这时，如果从句中表示的动作发生在过去，则谓语动词用had＋过去分词形式；如果指的时现在的状况，则用过去式(be用were)；指将来则用would(should, could)+动词原形。这里只看从句动作发生的时间，与主句的时态没有关系。
3、在It is (high) time (that)…句型中，后面的从句的谓语动词常用过去式(be的过去式用were), 或用should+动词原形(should 不能省略)来表示。这句话的意思是“（现在）该…”。For example: It is time we left/should leave. It is high time that you got married.
4、在 I would rather (that)…句型中，后面的从句的谓语动词用过去式(be的过去式用were)。这句话的意思是“我宁可…”，表示说话人的意愿。 For example:
I’d rather I were in the rain now. I’d rather you did not tell him.
5、用在suppose开头的祈使句中，从句的谓语动词变化与as if后面的动词变化规律相同，用过去式、过去完成式、或过去将来式。意思是“假如…”，但suppose 是动词，不是连词。如： Suppose the boss walked in. What should I do?
Suppose Saddam had not been captured. What would the U.S. do?
Suppose Chen Shui-bian should declare Taiwan independent. What would China do?
6、用在for fear that或lest引导的从句中，表示“怕…”“万一…”等意思。从句的谓语动词用should＋
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
动词原形，should 可以省略。如：
She closed the windows for fear that she (should) catch cold.
The officer forbade the use of artillery lest the city’s industry be damaged. Lest the wall should collapse, they evacuated from the building.
7. 在表示建议、要求、命令等意思的动词，如arrange, command, demand, desire, insist, order, propose, request, require, suggest, beg, move（提议）后面的宾语从句中，谓语动词用should + 动词原形，should 可以省略，而引导宾语从句的that 不能省略。例如： We suggested that we (should) have a meeting. We insisted that they (should) go with us.
The doctor ordered that she (should) stay in bed for a few days. He demanded that we (should) start right away.
The commander ordered that the bridge (should) be bombed. The villagers requested that the old building not be pulled down. Now let’s do some translation: 总经理坚持该项目必须按计划执行。
The general manager insisted that the project be carried out as planned. 省长请求再给他一次机会。
The governor requested that he be given another chance. 美国要求伊朗必须无条件放弃其核武器计划。
The United States demanded that Iran should unconditionally give up its nuclear weapon program (program to develop nuclear weapons) 最高法院裁定此案必须重新审理。
The Supreme Court ruled that this case be retried. 医生建议，即使在节假日人们也不应该熬夜。
8、使用上述表示建议、要求、命令等意思的动词派生的名词，或在这些动词用作名词时，名词之后的从句用虚拟语气，即从句的谓语动词用should＋动词原形，should 可以省略。从句的引导词that 不能省略。这与上述第7项类似。如：
He made a request that he (should) be allowed to take 3 days off. = He requested that he be allowed to take 3 days off.
Our suggestion is that education not be industrialized. = We suggest that education not be industrialized.
The president’s decision is that the war against terrorism be launched at the right time. =The president decided that the war against terrorism be launched at the right time.
9、上述动词在It is suggested that…, It is required that…, It’s requested that…, It’s ordered that…, It’s arranged that…句型中，that 之后的从句用虚拟语气，即谓语动词用should+动词原形, should 可以省略，但引导词that 不能省略。如：
It was suggested that he attend the conference. It was requested that the trial be openly reported.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
10、在It’s important (imperative, necessary, essential, vital, desirable, advisable, better) that…句型中，that 引导的从句用虚拟语气，即谓语动词用should ＋ 动词原形,should可以省略。这个句型表示说话人的意见、要求等。 For example:
It is essential that there should be enough food and clothing for the winter. It is desirable that your wedding be postponed until next July.
It is imperative that the board chairman be present at the board meeting.
另外，在一些习惯用语中也有虚拟语气的形式。但最好把这些习惯用语作为一种句型来记住。如： May you be happy! May you succeed!
Long live the People’s Republic of China! Everybody leave the room! You had better not resign. I would rather not tell you.
总之，虚拟语气是英语中的一个难点，因为虚拟语气的用法和句型较多，动词的变化比较复杂。在学习的时候要逐个过关。同时，也要善于发现虚拟语气的规律。根据动词的变化，大致可以把虚拟语气分为三种： 一种是动词用过去式，过去分词式，或过去将来式，这主要是用if…, wish, suppose的情况； 一种是动词用should+动词原形（should可以省略），这主要用于表示建议、要求、命令等意思的动词或名词后面所接的从句，以及It is important (necessary) that…后面所接的从句；
一种是动词用过去式，如It is (high) time (that)…和I would rather 后面的从句。同学们还可以自己总结适合自己的规律，如把虚拟语气句型可以分为用于简单句、条件状语从句、宾语从句、主语从句、表语从句、定语从句、同位语从句等。
Now let’s do some exercises to consolidate what we have learned about subjunctive mood:
四、非谓语动词
1、我喜欢做饭。“ I like cooking. ”
本句中，“like”（喜欢）是谓语。“cooking”（做饭）是宾语，用动名词形式。又如：“ He likes cooking. ”在英语中。谓语动词经常随着主语的人称、数而变化，但动名词作宾语时是不变的。 2、对我来说，学英语不容易。“ It\\' s not easy for me to learn English.”
3、从太空看，地球是个蓝色的球体。 “Seen from the space, the earth is a blue sphere.” 请比较这些句子的中英文。在这几个汉语句子中，做饭、学英语、从太空看分别作句子的宾语、主语和状语，但是其动词形式“做”、“学”、“看”没有变化。而在这几句英语中，“做饭”变成了cooking, “学”变成了to learn，“看”变成了seen. 动词形式发生了变化，而且必须发生变化，因为这些句子有另外的谓语动词。因此这些动词叫做“非谓语动词”，又叫“非限定性动词”,他们没有人称和数的变化。这是英汉动词的巨大差别，也是中国人学英语的一个难点，同时也是在使用英语时容易犯错误的地方。需要特别注意的是：英语的单句一般只有而且必须有一个主谓结构，即一个谓语，如果单句中出现了另外的动词，这些动词就要改变形式。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
以上英语句子中cooking, to learn, seen 等具有动词特征，但是在句子中不能作谓语的动词形式，就叫动词的非谓语形式，也叫非谓语动词。
我们再比较 “I like cooking.” 与 “He likes cooking.”这两句话主语不同，谓语动词like形式变了，但意义没有变化。而cooking 没有任何变化。再看 “It is not easy for me to learn English.” 和 “It is not easy for him to learn English.” “对我”for me, “对他”for him之后的 “to learn”没有任何变化。可以看出，非谓语动词是不随人称和数的变化而变化的，它们不受人称和数的限定，所以又叫“非限定动词”。
动词在句子中除了充当谓语外，还可以起名词、形容词或副词的作用，在句子中充当主语、宾语、表语、补语、定语和状语。这就是动词的非谓语形式。当句子中需要用某种动作作主语、宾语或作某种修饰、说明的成分时，就要使用这种形式。 动词的非谓语形式有三种：
（1）动词不定式：to study (to + 动词原形) （2）分词：studying (现在分词)、studied (过去分词) （3）动名词：studying (形式与现在分词相同)
动词非谓语形式仍具有动词的一般特征，可以带有宾语、状语等构成短语。 动词非谓语形式有以下几种形式变化（以write为例）： 形态 一般 动词不定式 进行 完成 完成进行 一般 现在分词和动名词 A、 动词不定式 其形式是“to+动词原形”。 to是不定式符号，无词义。其否定式是在to前面加上not, never等否定词。 不定式可以有自己的逻辑主语，由for引出，加在不定式短语前面。
如果不定式的逻辑主语是表示不定式动作的承受者，则不定式用被动语态。所谓逻辑主语，就是指非谓语动词等动作的执行者。由于非谓语动词等带有动词的特征，但又不是谓语动词，所以这个动作的执行者就不能称为主语，而在逻辑上又是这个动作的执行者，所以就称为逻辑主语。
如果不定式逻辑上的主语是这个不定式所表示的动作的承受者，这个不定式一般要用被动语态。疑问词（who, whom, whose, what, which, when, where, why, how还包括whether）等后面加不定式构成不定式短语，可做主语，表语，宾语等。
（一）作主语。 在不定式短语作主语的句子中，往往用 it 作形式主语，而不把不定式短语放在句子的后面。如：
To die like that is a terrible thing.=It is a terrible thing to die like that.
象那样死去是一件可怕的事。（ it 作形式主语，把真正的主语to die like that放在后面） To know oneself is difficult.=It’s difficult to know oneself.
完成 一般 主动 To write To be writing To have written To have been writing Writing Having written 被动 To be written To have been written Being written Having been written written 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
有自知之明不容易。
To tell a lie is not always easy.= It’s not always easy to tell a lie. 撒谎并非总是容易。
Never to offend anyone is my principle. 永远不得罪任何人就是我的原则。 It’s against nature to remain single. 保持单身是违反自然的。 To see is to believe. 眼见为实。
For a dog to die like that is a terrible thing. = It is a terrible thing for a dog to die like that. 一条狗象那样死去是一件可怕的事。（for a dog是不定式的主语）
For one to know everything is impossible.= It’s impossible for one to know everything. 一个人什么都知道是不可能的。
For his brother John to go to sea seems natural.= It seems natural for his brother John to go to sea. 他兄弟John去当水手是很自然的事。
It’ll be a great shame for you to forget her. 你要是把她忘了，那可太不应该了。 It’s not proper for us not to accept the invitation. 我们不接受邀请不合适。（否定）
It has not yet been decided when and where to discuss her resignation. 何时何地讨论她的辞职还没定。
但是，下列形容词做表语时，不定式的逻辑主语由 of 引出：
careless粗心的，clever聪明的，cruel残忍的，foolish愚蠢的，good好的，kind好心的 ，naughty淘气的，nice好的，polite礼貌的，right正确的，rude无礼的 ，silly愚蠢的，stupid傻的，unwise不明智的，wise明智的，wrong错误的，等等。 为什么这些词要用 of 引出不定式呢？
因为这些形容词都是描写人的性格和特点的形容词。“It is + 形容词 ＋of sb + to do sth”这样的句型更强调某人如何如何，可以改写为：“Sb + be + 形容词 + to do sth.” 而“for sb to do sth”这一结构更强调做某事如何如何。例如：
1、 It is difficult for me to learn English. 更强调学英语很难，不能写成 I am difficult to learn English. （这句话含有逻辑错误。）
2、 It is unwise of you to go to the United States at this time. =You are unwise to go to the United States at this time. 强调你不明智。
It’s very kind of you to come to see us off. =You’re kind to come to see us off. 你来为我们送行太好了。
It’s unwise of him to drink and smoke so much.=He is unwise to drink and smoke so much. 他喝这么多酒、抽这么多烟是不明智的。
It’s extremely cruel of John to kill animals. John杀害动物真是残忍之极。 It’s rude/polite of Jack to say this to her. Jack对她说这个，很无礼/礼貌。 （二）作宾语及宾语补语。
1、有些及物动词常用动词不定式作宾语。常见的这类动词有：afford负担得起，
agree同意，arrange安排，ask要求，attempt试图，beg乞求，begin开始，choose选择，claim声称，consent同意，dare敢，decide决定，decline谢绝，desire欲想，demand要求，determine决

在had better（最好），would rather（宁愿），would sooner（宁愿），would (just) as soon（宁愿），cannot but（不能不，不由得不），cannot help but（不能不，不由得不）等成语后面也跟不带to的不定式：

We demanded them to give us a definite answer.我们要求他们给个确切的答复。 正确的句子：

We demanded that they give us a definite answer. 我们要求他们给个确切的答复。 （三）作定语。
不定式短语作定语时，一般放在被修饰的词之后，有些名词的后面常用不定式作定语。常见的有：ability能力，agreement一致，协议，ambition抱负、野心，anxiety焦急，attempt试图，campaign战役，chance机会，claim声称，courage勇气，decision决定，determination决心，drive努力，eagerness殷切的心情，effort努力，failure失败，hope希望，intention目的意图，motive force动力，movement运动、协议，need需要，opportunity机会，plan计划，promise诺言，readiness乐意，refusal拒绝，reluctance勉强不愿，resolution决心，tendency倾向，right权力，struggle斗争，threat威胁，time时候，way方法，willingness愿意，wish希望。

不定式短语可以和表示情绪的形容词和过去分词连用，有时说明产生这种情绪的原因，有时不是说明原因，而是和形容词一起说明主语的情况。 常见的这类形容词和过去分词有：

（七）不定式的时态。动词不定式一般有三种时态形式，即一般式、进行式和完成式。
（1） 一般式（to+动词原形）：表示与主句谓语动词动作同时（或几乎同时）发生或在主句谓语动词之后发生的事情。例如：
We’re happy to have you on our side. 有你在我们这边我们很高兴。 I saw him go out. 我看见他出去了。（ 不定式go out 与 see同时发生。） They invited me to have dinner with them. 他们邀请我和他们一起吃晚饭。 I hope to see you again. 我希望再见到你（to see发生在hope之后）
（2） 进行式（to be+现在分词）：表示主句谓语的动作发生时，不定式动作正在进行。例如： She’s said /believed to be living nearby. 据说/据信她就住在附近。
When he came in, I happened to be sleeping in bed. 他进来时，我碰巧正在床上睡觉。 They seem/appear to be enjoying themselves. 看上去他们似乎很快活。

如：I’m glad to have met your parents here. 我很高兴在这儿见到了你父母。（已见过）
I’m sorry to have kept him waiting for me so long. 我很抱歉让他等了我这样久。（已经等过了）（八）不定式的被动语态。当不定式的逻辑主语是这个不定式所表示的动作的承受者时，不定式一般要用被动形式。不定式的被动形式有两种： 一般式：to be+过去分词 完成式：to have been+过去分词 例如：
You’re lucky to have been accepted . 你很幸运已经被接受了。 These criminals are to be hanged . 这些罪犯是将被绞死的。 We’re glad to have been invited. 受到邀请我们很高兴。 What’s to be done next? 下一步做什么？
It is an honor for me to be asked to speak here. 我很荣幸应邀在这里讲话。 （八）为了避免重复，不定式可省略，但to有时保留，有时不保留。 例如：

后面常省略不定式而保留to的结构，还有： used to 常常 be going to 打算 mean to 打算 ought to 应该 plan to 计划 want to 要想
（九）两个不定式由and, or, except, but, than 连接时，第二个可省略to，尤其是两个不定式紧密相连时。 例如:

B、动名词
动名词可以起名词的作用，在句子中作主语，宾语，表语，定语。动名词仍保留动词的一般特征，可以有自己的宾语和状语，构成动名词短语。 动名词的否定形式是在前面加上not, never等否定词。 （一）做主语和表语。动名词短语用and连起来做主语时，谓语用复数形式。 例如：
Fishing in this lake is forbidden. 这个湖里禁止钓鱼。
Going abroad for a visit and settling down abroad are two different things. 出国访问和在国外定居是两件不同的事情。
It seems that reading English is easier than speaking it.似乎读英语比说英语容易。 My favorite hobby is fishing/collecting stamps . 我最喜欢的爱好是钓鱼/集邮。
在It’s no use; It’s (no) good; It’s useless ; It’s (not) wise; It’s (not) worthwhile; It’s of great (no, little) importance 等习惯表达中，It为形式主语，而将做主语的动名词短语放在后面。例如： It’s no use /good ringing her up now. 现在给她打电话没用了。
Is it worthwhile bargaining two hours for two cents? 为两分钱讲价两小时值得吗？ It’s wise trying again. 再试一次是明智的。
It is of great importance fighting against pollution. 制止污染有重要意义。

没用了。本应该早些把他送来。
It is no good smoking; you’d better give it up. 吸烟没好处，你最好戒掉。 （二）动名词短语作宾语。
常用的能接动名词的动词有：admit承认，appreciate 感激，avoid 避免，advise 建议，can’t help 不禁，celebrate 庆祝，consider 考虑，complete 完成， contemplate沉思、打算，defer推迟，delay 延期，deny 否认，detest 痛恨，discontinue 停止， dislike不喜欢，dispute不同意，endure 忍耐，enjoy 喜欢， escape逃脱，excuse 原谅， fancy想象，feel like 想要， finish结束， 严禁，forgive 原谅，hinder 阻碍，imagine想象，keep 保持，mention 提到，mind 在意，miss 错过，pardon 饶恕、原谅，permit允许，postpone 推迟，practise 实践、练习，prevent 阻止， recall 回忆， report报告，resent 怨恨， resist抵制、阻止，risk冒险，stop 停止，suggest 建议，understand 明白、理解，等等。 例如：

I couldn’t risk missing that train. 我可不敢冒误了那趟火车的险。 下列动词既可用动词不定式又可用动名词做宾语：
abhor憎恶，attempt 试图，begin 开始，cannot bear 无法忍受，cannot stand无法忍受，cease停止，continue，继续,，decline 拒绝，deserve值得，disdain蔑视，dread害怕，endure忍耐，forget忘记，hate 痛恨，intend打算，learn学，like 喜欢，loathe厌恶，love喜欢，mean意思是、意味着，need需要，neglect疏忽，omit省略，忽略，plan计划，prefer更喜欢，propose建议，regret后悔，remember记得，require需要，scorn蔑视、瞧不起，start开始，try尝试，努力，entail必须，involve涉及，necessitate使成为必要，等。以上多数动词用不定式或用动名词作宾语意思一样，个别不同。 （三）动名词短语作介词宾语的时候最多。 尤其是在短语动词后面。如：
The children are fond of listening to pop music. 孩子们喜欢流行音乐。 Are you interested in going to the show? 你有兴趣去看演出吗？
Thomas insisted on doing it in his own way. 托马斯坚持按他自己的方法做这件事。 我们把这句话改为虚拟语气：Thomas insisted that he (should) do it in his own way. Excuse me for interrupting you. 请原谅我打扰你，

Before finishing your homework, you’d better not go out. 做完作业之前，你最好别出去。 改为用before 作连词：Before you finish your homework, you’d better not go out. （四）动名词也可以有自己的逻辑主语，就是在动名词短语前面加上物主代词或名词的所有格。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
带逻辑主语的动名词短语可做主语，宾语，表语等。在非正式文体当中，经常把物主代词简化为宾格人称代词，把名词所有格简化为名词。例如：
I insisted on his (him) going to the cinema with me. 我坚持要他和我一起去看电影。
I can hardly imagine Peter(Peter’s) sailing across the Atlantic Ocean in five days. 我简直不能想象彼得会在五天内横渡大西洋。
Linda’s coming will do you good.（主语） 林达的到来对你有好处。
What made him angry was their (them) laughing.（表语）使他生气的是他们笑。 （五）动名词的完成式和被动语态：
（1）完成式表示动名词的动作发生在谓语动作之前。例如：
I apologize for having broken my promise. 我没有遵守诺言，我道歉。
I don’t remember having talked with him before. 我不记得以前曾和他谈过话。
恨不相逢未嫁时。 → I regret not having met you before my marriage/before I got married. （2）当动名词的逻辑主语是动名词动作的对象或承受者时，动名词要用被动语态。例如： I could no longer stand being treated like that. 我再也不能忍受被那样对待。 She was proud of having been trained in the U.K. 在英国受过训，她感到自豪。 他不喜欢嘲笑别人。 →He doesn’t like laughing at others. 他不喜欢被人嘲笑。→He doesn’t like being laughed at. （六）某些动词可接不定式也可接动名词做宾语，但意义有差别。
（1）like, love, hate, prefer等表示喜爱，厌恶的动词后面，可用动名词也可用不定式作宾语，意义差别不大。但当这些词前面有should或would时，一定要用动词不定式作宾语。表示想要，愿意，打算。例如：
She likes dancing. But she wouldn’t like to dance with you. 她喜欢跳舞。（泛指）但他不喜欢和你跳。（特指）
He looked tired and I didn’t like to disturb him. 他看上去很累，我不想打扰他。

I hate to disturb you now, but I have no choice. 我真不想现在打扰你，但没有办法。 （2） forget to do sth.忘记去做某事（未做） forget doing sth.忘记做过某事（已做） 例如：
The light in the office is still on. She forgot to turn it off. 办公室的灯还在亮着。她忘记关了。（关灯的动作没做）

分词有现在分词和过去分词两种。
作为谓语，现在分词和be 一起构成进行时；过去分词和be一起构成被动语态，和have一起构成完成
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
时。 例如：
I am reading a novel by Maupassant. 我正在看一本莫泊桑写的小说。（现在分词和be 一起表示主语正在进行的动作。）
Mr. Robinson has drunk five glasses of wine already. 鲁宾逊先生已经喝了五杯酒了。（过去分词和have 一起表示主语已经完成的动作。）
The gold fish bowl was broken by Xiao Tao just now. 金鱼缸刚才被小陶打破了。（过去分词和be 一起表示主语是动作的承受者。）
作为非谓语形式，分词可用作形容词和副词，在句子中充当定语、表语、补语和状语。但它仍保持动词的一般特征，可以有自己的宾语和状语。分词和自己的宾语、状语构成分词短语。
现在分词有一般式和完成式。它的一般式表示和谓语动词所表示的动作同时发生的行为或存在的状态；它的完成式（having + 过去分词）表示在谓语动词所表示的动作之前发生的动作或存在的状态。 现在分词有主动语态和被动语态(being + 过去分词)。
过去分词只有一般式，表示在谓语动词所表示的动作之前发生的动作。过去分词（及物动词）本身可以表示被动的含义，因而没有别的被动形式。 例如：
Having failed three times, he didn’t want to try again. (=As he had failed three times, he didn’t want to try again.) 他失败了三次，不想再干了。（having failed 表示发生在前的动作）
Walking along the sands, Crusoe saw in the sand the mark of a man’s foot. (=While he was walking along the sands, Crusoe…) 克鲁索沿着沙滩走的时候，看见沙上有人的脚印。（walking 表示同时发生的动作）
The question being discussed seems important. (=The question is being discussed. It seems important.) 正在讨论的问题似乎很重要。
The old days are gone. 旧时代一去不复返了。（gone 表示完成的状态）
I had my hair cut yesterday. 我昨天理发了。（cut 是及物动词的过去分词，表示“被人理发”。） 分词的否定形式是在分词短语前面加上not, never等否定词构成。 例如：
Not fearing the fire, the child touched and got a finger burnt. 小孩儿不知道怕火，用手去摸，把手指烫了。
Not knowing how to find the subway, I asked a policeman for help. 我不知道怎样找到地铁，就去找警察帮忙。
（一）现在分词和过去分词的区别
（1）在语态上现在分词表示主动的意思，表示它所修饰的人或物的行为；及物动词的过去分词表示被动的意思，表示它所修饰的人或物是动作的承受者。换言之，现在分词是它修饰的成分所作出的动作，过去分词是它修饰的成分所承受的动作。 例如：
convincing facts 有说服力的事实 / convinced audience 被说服了的听众 the exploiting class 剥削阶级 / the exploited class被剥削阶级
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
a frightening dog一条让人害怕的狗 / a frightened dog一条被吓坏了的狗 driving gears主动齿轮 / driven gears从动齿轮
（2）在时间上，现在分词往往表示动作正在进行，过去分词表示动作已完成。 例如：
the rising sun (正在升起的太阳) / the risen sun（升起的太阳） the falling rain（正在下的雨）/ the fallen leaves（落下的树叶） stolen money（被盗的钱/偷来的钱）/ill-gotten wealth（不义之财） a high-flying kite（高飞的风筝） 再看一些例子：
boiling water 沸腾的水/boiled water 开水/developing countries 发展中国家/developed countries 发达国家/an exciting story 令人激动的故事/ excited people 激动的人们 （2）在时间上，现在分词往往表示动作正在进行，过去分词表示动作已完成。 再看一些例子：
surprising news令人惊讶的消息/a surprised man受惊吓的人/an inspiring leader具有号召力的领袖/the inspired soldiers受到鼓舞的士兵/a delighted speech令人高兴的演说/the delighted audience(感到)高兴的听众/a moving film动人的电影/the moved children受到感到的孩子们/a box containing tea装茶叶的盒子/the tea contained in a box装在盒里的茶叶/ falling snow正在下的雪/fallen snow box落在地上的雪
（3）做表语时的不同。现在分词做表语表示主语所具有的特征，意思是“令人如何”。过去分词多表示主语所处的状态，意思是“感到如何”。 例如：
His lecture is disappointing。I’m disappointed。他的演讲令人失望。我感到失望。
We are surprised to hear the news。The news is surprising。我们听到那消息吃了一惊。那消息令人吃惊。
The situation is encouraging。 We’re encouraged。形式使人鼓舞。我们感到鼓舞。
常用的还有：amusing/amused，astonishing/astonished，disappointing/disappointed，exciting/excited
，
frightening/frightened
，
interesting
interested
，
moving/moved， relaxing/relaxed，satisfying/satisfied，shocking/shocked，surprising/surprised，terrifying/terrified，tiring/tired，worrying/worried等等。
（4）做状语的区别，分词短语在句中可做时间、原因、方式、伴随状语。现在分词的动作和谓语动作同时或几乎同时发生、意思是主动的。而过去分词的动作在谓语动作之前发生、意思是被动的。 例如：
Seeing nobody at home，she decided to leave them a note。看到没人在家，她决定给他们留个条。(主动意义，几乎同时)
The secretary worked late into the night，preparing a speech for the president。秘书工作到晚上很晚，给总统准备一篇演说。(主动意义，同时)
Tired of the noise，he closed the window。对噪音感到厌烦，所以他把窗户关上。(被动意义，在谓语之前)
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
Deeply moved，she thanked me again and again。她深深地受了感动，再三谢我。(被动意义，在谓语之前)
Persuade by my mother，she gladly went there alone。在我母亲劝说下，她才高兴地独自去那里。(被动意义，在谓语之前)
如果现在分词的动作在谓语动作之前发生，现在分词要用完成形式，但意思仍然是主动的。 例如：
Having watered the vegetables，they began to pick up the Apples。=After they had watered the vegetables，they began to pick up the apples。他们浇完了蔬菜之后就开始摘苹果。 Having finished the work，he packed his tools and left。完工后，他收拾起工具走了。 分词做状语时，前面可用连词或介词。 例如：
After eating my dinner quickly，I went to see Jim off。我赶快吃过晚饭就去给吉姆送行。
Though built before the Second World War，the engine is still in good condition。尽管是在二战以前建的，这引擎仍然处于良好状态。
Unless paying by credit card，please pay in cash。如果不用信用卡付款，请用现金付。 Tom will never do this unless compelled。汤姆永远也不会干这种事，除非被逼无奈。 She’s been quite different since coming back from America。从美国回来后，她大变了。 （二）用法
1．作定语。作定语的分词通常放在被修饰的名词之前。如果被修饰的词是something，anything，everything，nothing等，则分词放在这些词之后。分词短语通常放在被修饰的名词之后。 例如：
This is an interesting book。(=This is a book。It is interesting。)这是一本有趣的书。
There is something interesting in the news。(=There is something in the news。 It is interesting。)消息中有些有趣的事。
The man sitting by the window is our math teacher。(=The man who is sitting by the window is our math teacher。)靠窗户坐着的那个人是我们的数学老师
The machine run by the old worker is made in Shanghai。(=The machine that is run by the old worker is made in Shanghai。)那位老工人开的机器是上海造的。
Most of students singing were girls。(=Most of the students who were singing…)唱歌的学生多数是女生。
Many of the villagers questioned refused to answer。(=Many of the villagers who were questioned…)被问的许多村里人都拒绝。 注意：（1）分词作定语与动名词作定语的区别：
分词和它所修饰的名词有逻辑上的主、谓关系。动名词则没有这种关系，而表示它所修饰的词的用途或有关动作。 现在分词 A sleeping child(a child who is sleeping)正在睡觉的孩子 动名词 A sleeping car(a car for sleeping)卧车 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
A flying bird(a bird that is flying)飞鸟 A swimming girl(a girl who is swimming)游泳的女孩 The running water(the water that is running)流水 A flying course(a course for flying)飞行课程 A swimming pool(a pool for swimming)游泳池 The running track(the track for running)跑道 现在分词和它所修饰的名词都要重读，动名词所修饰的名词则不必重读。 （2）现在分词作定语时，它表示动作正在进行或与谓语动词所表示的动作同时发生(或差不多同时发生)。 例如：
Who is the boy dancing over there？在那儿跳舞的少年是谁呀?
The girls swimming in the sea were in danger。 在海里游泳的姑娘们有危险。 如果两个动作在时间上有先后，一般不能用现在分词作定语，而往往用主从复合句结构。 例如：
The man who has gone to Shanghai will be back again。到上海去的那个人会回来的。
The teacher wants to talk to the students who smashed the windows。老师要找打破了窗子的那个学生谈话。
（3）be的现在分词being不能用作定语(可用作状语或被动语态中的助动词)。表示这种概念时，也用主从复合句结构。 例如：
He has a brother who is a worker。他有一个当工人的兄弟。
2、作状语。分词和分词短语作状语时，可以表示时间、原因、行为方式等意义。表示时间和原因的分词短语相当于对应的状语从句。 例如：
Seeing the teacher entering the room，the students stood up。(=When the students saw the teacher entering the room，They stood up。)学生们看见老师走进房间，都站了起来。 (时间) Heated，the Metal expands。 (=The metal expands if /when it is heated。)金属受热而膨胀。(条件、时间)
Being excited，I couldn’t go to sleep。(=As I was excited ，I couldn’t go to sleep。)我兴奋得睡不着觉。(原因)
Being a student，he was interested in sports。(=As he was a student，he was interested in sports。) 他是个学生，所以对体育运动感兴趣。(原因)
Inspired by Dr.Yang’s speech，Li Hua and his classmates decided to study physics harder。(=As they were inspired by Dr.Yang’s speech，Li Hua and his classmates decided to study physics harder。)李华和他的同学们受到杨博士讲话的鼓舞，决定更加努力学习物理。 (原因)
The children went away laughing。=The children went away。They laughed as they went。孩子们笑着走开了。(行为方式)
The professor stood there，surrounded by many students。(=The professor stood there。He was surrounded by many students。)教授站在那里，许多学生围着他。(行为方式)
While reading the newspaper，father nodded from time to time。(=While he was reading the
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
newspaper，father nodded from time to time。)看报时，父亲不时地点头。(时间)(分词前，可加表示时间的连词while或when。) 3、作宾语补足语。 例如：
Can you get the machine going again？你能使机器再动起来吗？ You should have your hair cut。你该理发了。 I saw him coming last night。我昨天晚上看见他来了。 4、作表语。 例如：
The film is very moving。这部影片很感人。 Your homework is well done。你的作业做得好。 The visitors looked surprised.参观者看上去很惊讶。
The boys were seen walking on the grass。有人看见孩子们在草地上散步。 5、作句子独立成分（分词有自己的逻辑主语时，称为独立主格结构。） 例如：
Flags flying，the army men marched in the streets。旗帜飘扬，军队在街上行进。 All his ribs broken，he lay half dead。他的肋骨全部折断，半死不活地躺着。
分词(短语)作状语时，其逻辑主语必须与句子的主语一致。如果不一致，必须用独立主格结构来表示，也就是在分词前面加上它的逻辑主语。
My wife had a long talk with Sally, explaining why she didn’t want the children to play together我妻子与莎莉谈了很长时间，解释她为什么不想让孩子们在一起玩。(现在分词explaining是句子主语my wife做的动作，它们之间是主动关系)
Given more attention，the trees could have grown better。如果对这些树多关心一些，它们本来会长得更好。(过去分词given表示的动作是句子主语the trees承受的动作，它们之间是被动关系) We explored the caves，Peter acting as guide。我们到那山洞探险，彼得做向导。 (独立主格) The train having gone，we had to wait another day。分词短语做状语时，前面可以加上连词或介词，但是分词短语和句子之间不能用并列连词(如but，and)，因为并列连词接的是两个并列成分，而分词短语只是全句的一个状语部分。分词和主句之间可用逗号。 例如：
误：Having been told many times，but he still couldn’t understand it。 正：He was told many times, but he still couldn’t understand it。
注意：（1）分词作状语时，逻辑主语即句子的主语;否则要用从句或独立主格结构来表示。 例如：
Looking out of the window，I saw lots of people there。(=When I looked out of the window，I saw lots of people there。)
我往窗外一看，看见那儿有许多人。 (looking out of the window的逻辑主语，就是句子的主语I。) （2）在see，hear，watch，notice等动词后，用动词不定式作宾语补语，通常表示(强调)动作从开始到结束的全过程。如果用现在分词作宾语补语，则通常表示动作正在进行。

例如：
We sat two hours and watched the teacher make the experiment。我们坐了两个小时，看老师做实验。(两小时一直在看老师做实验)
We passed by the classroom and saw the teacher making the experiment。我们走过教室，看见老师在做实验。(只是在走过教宰的一刹那间，看见老师正存做实验)
I saw him enter the room, unlock a drawer, take out a document, photograph it and put it back。我看见他走进房间，打开抽屉，拿出一份文件，拍了照又放回去(表示一个接一个的一系列动作的全过程时，用动词不定式。
I noticed them sitting in the corner and talking about something secret。我注意到他们坐在角落里在谈论什么秘密事儿。 (表示几个同时正在进行的动作，用现在分词)
（3）在“have+宾语+分词”的结构中，用现在分词或过去分词表示的意义不同。在“have+宾语+现在分词”的结构中，现在分词所表示的动作往往是主体让(叫、使、听任、允许)客体做的，或使客体保持或处于某种状态。 例如：
He had the fire burning day and night。他让火日夜燃烧着。
Father had me swimming the whole summer vacation。父亲让我整个署假天天游泳。
在“have(get)+宾语+过去分词”的结构中，过去分词所表示的动作往往是别人做的或与主体的意志无关。 例如：
Mary had her dress washed。玛丽叫别人洗了她的衣服。(衣服是被洗) had his legs broken。他的腿骨折断了。(表示与主体意志无关的客观遭遇) I had my watch stolen yesterday。昨天我的表被人偷了。(表是被偷) They had Jack beaten。他们叫人打了杰克。(Jack是被打)
（4）分词作表语时，现在分词有“主动”、“进行”、“使”等意义；过去分词有“被动”、“完成”“受”、“感到…”等意义。 例如：
The story is interesting。这个故事很有意思。(故事使人感兴趣) He is interested in dancing。他对舞蹈感兴趣。
（5）谓语动词的现在进行时和作表语的现在分词形式相同；被动语态动词谓语和作表语的过去分词形式相同，但两者的意思不一样。 试比较:
They are moving their bed.他们正在搬床。 (are moving是谓语，表示主体的动作) The story is very moving.这个故事很感人。 (moving是表语，表示主体的特征)
Her homework was done by her sister.她的作业是她姐姐做的。 (was done是谓语动词被动语态) Her homework is well done.她的作业做得很好。( done是表语)
（6）generally speaking（一般地说），roughly speaking（粗略地说），strictly speaking（严格地说）等现在分词结构都是习惯用语，在句子中作插入语。 例如：
Generally speaking，a footballer of 20 is better than one of 40。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
一般地说，二十岁的足球队员比四十岁的强。
（7）分词短语的逻辑主语就是句子的主语，而独立结构的逻辑主语和句子的主语是不同的。 例如:
The last bus having gone，we had to walk home. 末班公共汽车已开走了，我们只好走路回家。 （三）分词的时态和语态
过去分词可以表示“被动”和“完成”等意义，因此没有时态和语态方面的形式变化。下面谈一下现在分词的时态和语态。
1.现在分词的完成式(having+过去分词)表示的动作发生在谓语动词所表示的动作之前或两个动作在时间上有一定的间隔。 例如:
Having written the letter，John went to the post office. (=After he had written the letter，John went to the post office. 约翰写完信后，就去邮局了。
Having lived in Beijing for years，Lao Wang knows the city quite well. (=As he has lived in Beijing for years，Lao Wang knows the city quite well.) 老王在北京住了多年，所以对这个城市很熟悉。
Having drunk two glasses of water, Xiao Ma felt a little better. (=After he had drunk two glasses of water Xiao Ma felt a little better.) 小马喝了两杯水，感觉好一些了
一般式和完成式现在分词都可以表示先后接连发生的动作。在可能引起误解的场合应该用完成式现在分词表示先发生的动作。 例如:
Opening the drawer，he took out his wallet. (=He opened the drawer and took out his wallet.) 他打开抽屉，拿出钱包。
Coming into the room，he put down his bag. (=he came into the room and put down his bag.) 他走进房间，放下提包。
Having brushed his teeth，Mr. Brown came downstairs for breakfast. 布朗先生刷过牙，就下楼来吃早饭。
(此句如写成:Brushing his teeth, Mr. Brown came downstairs for breakfast.可能指“边刷牙，边下楼’。) 2.现在分词的被动语态(being +过去分词)通常表示“正在被…”的意思。如强调现在分词表示的动作发生在谓语动词所表示的动作之前时，可用现在分词被动语态的完成式(having + been +过去分词)。 例如:
The bridge being built will be completed next month.正在修建的那座桥将于下月完成。
Having been kept out of the room about half an hour for his returning late，Tom was let in.汤姆回来晚了，所以被关在门外半小时左右才让他进去。

五、独立主格结构
独立主格结构由名词或代词加上其他成分(分词、不定式、名词、代词、形容词、副词或介词短语)构成。 独立主格结构没有主语和谓语，所以在语法上不是句子。但多有名词或代词表示的逻辑主语，分词或不定式表示的逻辑谓语，有时还有其他修饰成分。(判断一个结构是否是句子的标准就是看看这个结构是否有谓语动词。)这种结构通常在句子中起方式、时间、原因、条件等状语或状语从句的作用，主要用于书面语。使用动词非谓语形式的独立主格结构可以改为句子形式(从句):独立主格结构加上连词，非谓语动词改为谓语动词形式，这样就成为从句了。 例如:
Today being Sunday, the library isn\\' t open.今天星期天，图书馆不开放。 (原因)改为从句:
As (Since) today is Sunday, the library isn\\' t open. 例如:
There being no buses，we had to take a taxi. 没有汽车了，我们只好坐出租车了。 Because there were no buses, we had to take a taxi.
The signal given，the bus started.信号发出后，公共汽车就启动了。 (时间)改为从句:
After the signal was given, the bus started.
The boy followed that man here，and climbed in，sword in hand.少年跟那个人到这里，并爬了进来，手里拿着剑。
The boy followed that man here，and climbed in，and had a sword in his hand.
The mid-term examination is over, the end-of-term examination to come two months later.期中考试结束了，两个月之后进行期末考试.
The mid-term examination is over, and the end-of-term examination is to come two months later. Weather permitting, we\\' 11 visit the Great Wall.如果天气允许的话，我们就去参观长城。 If weather permits, we\\' 11 visit the Great Wall.
The boy followed that man here, and climbed in, sword in hand.少年跟那个人到这里，并爬了进来，手里拿着剑。(伴随状语)
上文例句中sword in hand是由“名词+介词短语”构成，表示伴随的情况。这种表示伴随情的独立主格结构，有时可以用with
引出，二者的意思是一样的，with结构更加口语话，更加常用。
She left the office with tears in her eyes.她眼里含着泪水，离开了办公室。
The teacher walked into the classroom, with a ruler under his arm and some books in his hand.老师胳膊底下挟着一把尺子，手里拿着几本书，走进了教室。
The teacher walked into the classroom. He was holding a ruler under his arm and some books in his hand.
Tian\\' anmen Square looks magnificent with all the lights on.华灯齐放，天安门广场显得美丽动人。 With the boy leading the way, we found his house with no difficulty.由这孩子领路，我们毫不费劲地找到他的家。

六、一致关系
英语的一致有三种:主谓一致，代词一致，肯定与否定一致 （一）主语与谓语的一致
英语语法要求，主语如果是单数，谓语动词也要用单数形式;主语若是复数，谓语动词也要用复数形式 例如:
She likes to eat well.她好吃
We all like good food.我们都喜欢好饭菜。
Everybody was happy with the decision. 人人都对这个决定感到高兴。 I am a doctor.我是个医生。 （二）概念一致
1. And连接的两个或多个单数名词作主语时，谓语动词用复数形式 His opinion and mine are different他的观点和我的是不同的。 Bob and Peter are deadly rivals. Bob和peter是死对头。
What she says and what she does are totally different. 她说的和做的完全不同。 但是如果and连接的是指一个单一概念时，谓语动词用单数。
Bread and milk has been my breakfast for years. 牛奶面包多年来一直是我的早餐。 Her lawyer and old friend is going to marry her.她的律师和老朋友要娶她。 All this effort and sacrifice has come to nothing. 所有这些努力和牺牲都白费了。 由and连接的单数主语分别有many a，ever y，each，no修饰时，动词用单数。
如：During the holidays, every train and every plane was crowded.假期期间每列火车及每架飞机都非常拥挤。
No boy and no girl has the right to refuse education. 男孩和女孩都没有拒绝教育的权利。 Man a man and man a woman was moved b this picture。许多男男女女都被这幅画感动。 2.如果主语是一个抽象概念(如不定式、动名词、主语从句等)谓语动词用单数形式。如果主语是用and连接的两个或多个抽象概念，谓语动词用复数形式。
如：Swimming jogging and cycling are all goad farms of sports exercises.游泳、慢跑和骑自行车都是很好的运动形式。
To live to eat is not a very goad attitude toward life. 活着就是为了吃不是好的生活态度。 To live to eat and to eat to live are very different attitudes toward life.
以what，who，why，haw, whether等wh一词引起的从句做主语时，谓语动词通常用单数;由and连接的两个主句如果指两件事，动词用复数。
例如:What he is doing is not clear yet他在干什么还不清楚
What he is doing and whether I know him are two different things.他在干什么和我是否认识他是两件不同的事。
What she told me is none of your business. 她和我说的什么用不着你管。 What she told me and what she told you are totally different things.
以what从句为主语的“主一系一表SVC\"句型中，如果主句的表语是复数，主句谓语动词用复数形式;what从句本身是复数意义，主句谓语动词也可用复数。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
如：What I need buy now are four tea cups and a pair of sports shoes. 我需要买的是四只茶杯和一双运动鞋。
What were thought to be five dogs were actually five sheep. 被认为是五条狗的东西实际上是五只羊。
3.集体名词family，class，crew(全体船员或机组人员)，crowd, group, committee, audience, government, public, team, staff, population等做主语时，若作为一个整体看待，后面谓语动词用单数; 如就其中每一个成员来考虑时，则用复数。 例如: My family is a big one.我家人多。
My family are all music lovers. 我全家人都爱好音乐。
Eighty percent of China\\' s population are peasants. 百分之八十的中国人口是农民。 China has a huge population. 中国有众多的人口。
The population of China is the largest in the world. 中国的人口是世界上最多的。
People, police, cattle,(牛)，militia(民兵)，poultry(家禽)，vermin(害出)等作主语时，后面的动词要用复数。
4.不定代词either，neither，ever y，each，one，the other, another以及所有的复合不定代词作主语时，谓语动词只用单数，包括“every/each/no……and every/each/no……”作主语时。 如：Every/Each plane and every/each pilot is ready to take off. 每架飞机和每个飞行员都已准备好起飞。 No plane and no pilot is ready to take off. 没有一架飞机、没有一个飞行员已准备好起飞。
Here are two books. Either of them is worth reading. 这有两本书，都值得一读。

Everyone is here. No one is absent. 大家都到了，没有人缺席。 Somebody is using the phone. 有人在用电话。
I have two sisters. One is here, and the other is not here. 我有两个姐妹，一个在这儿，一个不在这儿。
Each day is better than the one before. 一天比一天好。 Either day is OK. 两天中哪一天都行。
5. what，who，which，any，mare，some，half，mast，all，none.等代词可以是单数，也可以是复数，主要靠意思决定。但指不可数名词时作单数看待。
6.表示时间、重量、长度、价值等的单位名词，尽管是复数形式，如果作整体看待，动词都用单数形式。如果看作组成该数量的一个一个的个体，则动词用复数。
如：Twenty miles is a long way to walk. 走二十英里可是很长的一段路。 Ten years is a long time。十年很长。 Eight minutes is enough. 八分钟够了。 Twelve dollars is too dear. 十二美圆太贵了。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
There are six silver dollars in each of the stacking. 每只袜子里有六个一美元的银币。 7. “the+形容词”表示一类人时，谓语动词用复数。表示抽象概念或指个别事物时谓语动词用单数。 如：The old are well taken care of. 老人得到很好的照顾。 The beautiful is laved by all. 人人都爱美。
8. 如果主语由\"a kind/sort/type of this kind/sort/type of +名词”组成，不管名词是单数还是复数，动词通常用单数。
如：This kind of man annoys me. =This kind of men annoys me. 这种人让我烦。 This kind of apple is very expensive. = This kind of apples is…这种苹果很贵。
类似的还有:a portion of(一部分)，a series of(一系列)，a pile of(一堆)，a panel of (一个小组委员会)， 如：A series of accidents has happened here. 这里发生过一系列事故。
9. Means作“方法、手段”讲时，单复数同形，其前面有each, every, neither, either,等单数a念的定语时，谓语动词用单数;若有all, both，these等复数概念的定语时谓语动词用复数。 “None of the means”作主语时，谓语动词通常用单数。
如：There is/are no means of learning what is happening. 没法知道正在发生什么事。 No means is /are left untried. 没有没试过的方法了。 Every means is to an end. 每一种手段都能达到一种目的。 A bicycle is a means of transport. 自行车是一种交通手段。
All possible means have/Every possible means has been tried.所有的方法都试过了。 （三）就近一致
1.当主语由either...... or. neither...... nor , not only ...... but(also) 或or连接时，谓语动词通常和最临近的那个主语一致。
例如：Either you or he is to do the work. 不是你就是他来做这件事。
Not only you but also Tom often comes late to class. 不光是你，汤姆上课也迟到。 Neither the children nor the teacher knows anything about it. 孩子们和老师都不知道这件事。
2.当there be结构后面有并列主语时，谓语也和最临近的那个一致。 如：There is a dictionary and many books on the table. 桌子上有一本词典和许多本书。
There' re ten chairs and a table in the house. 屋子里有十把椅子和一张桌子。
Here is a pen, a few envelopes and same paper far you. 这儿有一支笔，几个信封和一些纸给你。
这种就近一致的情况在非正式文体中越来越普遍。但在下列情况不提倡模访。 如：Where is your mother and sisters? 你妈妈和你姐妹到哪儿去了?
Is your sister and her husband coming to see you? 你姐姐和姐夫要来看你吗?
One in ten are expected to take part in the contest.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
预计每十个人就有一个要来参加这次比赛。
3.做主语的名词或代词后接with，together with，along with，as well as等短语时，谓语动词一般和前面名词或代词一致。这些短语前后可用可不用逗号。 如：A woman with a baby is coming to the hospital 一个妇女抱着个婴儿正向医院走来。
The girl, as well as the bays , has learned to drive a car. 这个姑娘和那些那孩子一样也学会了开汽车。 （四）代词一致
代词一致是指句子中代词应在数、性、人称等方面彼此保持一致， 如：One must do one\\' s best to increase production. Everybody talked at the tap of his/their voice.
If anyone calls, tell him I\\' 11 be back in a moment. (him也可用him or her代替)
在写作中，如果表示不定的人，可以用you, we, one等，需要注意的是：同一篇文章中，只用同一个不定代词，而且所有格要与其一致。 （五）肯定与否定一致
下列形容词、副词、代词从肯定句变成否定句时，须作相应的变化: 肯定句 We\\'ve had some money. I was talking to someone They sometimes visit us. He has arrived already. Li is coming too. Both of us are going. He likes both of them. 否定句 We haven\\'t had any money. I wasn\\'t talking to anyone. They rarely (never, seldom) visit us. He hasn\\'t arrived yet. Li isn\\'t coming either. Neither of us are going. He doesn\\'t like either of them. 注意：“so/neither+助动词/情态动词+名词/代词”结构中须用倒装语序， 如：My wife likes classical music very much and so do. She doesn\\' t like jazz and neither do.
七、定语从句
所谓从句，就是一个主谓结构相当于整个句子(这样的句子叫复合句)的一个成分，因此，从句不能单独使用。在复合句中修饰名词或代词、作定语的句子叫定语从句。定语从句是中国人学英语最重要的难点之一。 其实定语从句很有规律，总结如下:在关系代词中that既可指人又可指物、既可作主语又可作宾语，因此，除了在非限定性定语从句中，用that一般不会出问题。
关系副词的用法比较单一，它们从句中只起状语的作用，表示时间的就用who门，表示地点的就用where，而why只修饰一个词，即reason。
定语从句所修饰的词叫“先行词”，因为它总是处在定语从句的前头，比定语从句先行一步。 引导定语从句的词叫关系词，包括关系代词和关系副词。 关系代词：
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
who，which，that作从句的主语
whom，which，that作从句的宾语(可省略) whose从句中作定语
以下情况只能用that，不能用which:
i. 先行词为不定代词all, little, none，any，every，no，much, anything, nothing ii. 先行词有最高级和序数词修饰时(包括: the only, the very, the same, the last, the next等)
iii. 先行词既有人又有物的时候 以下情况只能用which，不能用that;
① 引导非限制性定语从句(包括代表整个主句的意思时) ② 介词+关系代词的结构中 关系副词：
when指时间，在定语从句中作时间状语 where指地点，在定语从句中作地点状语
why指原因，在定语从句中作原因状语，只修饰reason。
如果用定语从句把两个句子合二为一:首先找出两个句子当中相同的部分，定语从句修饰的就是这一部分。要把其中一个句子变成定语从句，就要把这句中相同的那个部分用一个关系词来代替;代替时，先看被代替的部分是指人还是指物、再看它作什么句成分。指人并作主语的，就用who。或that;指人并作宾语的，就用whom或that;指人并作定语的，就用whose。指物并作主语的，就用which或that认指物并作宾语的，还是用which或that认是物并作定语的，就用whose或of which。这样找好并替换以后，再把这个关系代词放到要变成定语从句的那个句子的最前面(被代替的部分不能再保留，其它的词语一律不变)，这个句子就变成了定语从句。然后，再把这个定语从句整个放在被修饰的词后面，最后，如果还有其它句子成分，就把它们放到定语从句的后面，就行了。 例如：
Have you found the book? You were looking for the book yesterday.
在这两个句子中，the book是相同的，定语从句修饰的就是the book。把后面这一句变成定语从句，找个关系词来代替the book；在将要被变成定语从句的名子中，the book是物并作宾语，所以用which或that代替它。
然后把which或that放到本句的最前面，其它的词和语序一律不变。这时，就成了\"that/which you were looking for yesterday?”，再把这个定语从句整个放在被修饰的词后面，就成了“have you found the book that/which you were looking for yesterday?”定语从句就完成了，主句是问句，所以句末用问号。that/which代替的是原句中的宾语，原句变成了从句，它们仍然作从句的宾语。关系代词在从句中作宾语时可以省略，因此上句又可变成“have you found the book you were looking for yesterday?”. 关系副词与此同理。只是关系副词代替的是原句中的状语。在被代替 之前，这个状语中一定要含有一个与另一句相同的成分。
例如:This is the house甲I was barn and brought up in the house.在这两个句子中，in the house是句子里的地点状语，定语从句修饰的就是the house。把后面这一句变成定语从句。在将要被变成定语从句的句子中，in the house是地点状语，所以用where来代替它。然后再把where放到本句的最前面，
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
其它的词和语序来代替它。然后再把where放到本句的最前面，其它的词和语序一律不变。这时，就成了\"where}was barn and brought up\"。再把这个定语从句整个放在被修饰的词后面，就成了\"This is the house where I was barn and brought up.”，
定语从句就完成了，主句是陈述句，所以句末用句号。Where代替的是原句中的状语，原句变成了从句，它就作从句的状语。
(4) The hotel is an artistic building. We' ll stay in it. ……The hotel where we' 11 stay is an artistic building.
……The hotel (which/that) we' 11 stay in is an artistic building. ……The hotel in which we' 11 stay is an artistic building.
(5) Perhaps they' ve heard of the place. We went there for our holidays last time. ……Perhaps they' re heard of the place where we went for our holidays last time. 定语从句
请大家照上面的例子，把下面变定语从句的步骤说出来（括号里的可以省略）： （6）They’re redecorating the room. A conference will be held in the room. →They’re redecorating the room where a conference will be held.
→They’re redecorating the room (which /that) a conference will be held in. →They’re redecorating the room in which a conference will be held.
那么，“介词+关系代词”是怎么回事呢？原来上面这个例句，还有一种做法：This is the house. I was born and brought up in the house.在这两个句子中，the house是相同的，定语从句修饰的就是the house 。把后面这一句变成定语从句。在将要被变成定语从句的句子中，the house表示物而且是介词in的宾语，所以用关系代词which或that来代替。然后把which或that放到本句的最前面，其它的词和语序一律不变。这时，后面这一句就成了 “which/that I was born and brought up in”。再把这个定语从句整个放在被修饰的词后面，就成了“This is the house which/that I was born and brought up in”。定语从句就完成了，主句是陈述句，所以句末用句号。
which/that代替的是原句中的宾语，原句变成了从句，它们就作从句的宾语。关系代词在从句中作宾语时可以省略，因此上句又可变成“This is the house I was born and brought up in.”
但是，in可以提到关系代词的前面，不过这时不能用that，而且不能省略。所以上句又可变为“This is the house in which I was born and brought up.”这就是“介词+关系代词”的来历。
定语从句又分为限定性定语从句和非限定性定语从句。限定性定语从句把它的先行词限定在特定的意义之内，对先行词起限定的作用、是先行词必不可少的修饰语，没有它，整个句子的意思就会受到影响、就不完整。非限定性定语从句不对先行词起限定的作用，不是先行词必不可少的修饰语，只对先行词起补充说明的作用，没有它，整个句子的意思不会受到影响、仍然完整。非限定性定语从句相当于一个分句，翻译时也是把它当作分句处理的。非限定性定语从句和它的先行词之间要用逗号隔开；而限定性定语从句和它的先行词之间不能用逗号隔开。非限定性定语从句中除了不用that以外，其它关系词都可使用，使用方法与限定性定语从句一样。
例如：The supermarket which was opened two months ago is now closed down. 两个月前开的那家超市现在已经倒闭了。（限定）
The supermarket, which was opened two months ago, is now closed down.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
那家超市现在已经倒闭了，那家超市两个月前开的。（非限定） The book(which) you’re reading is mine . 你正在读的那本书是我的。（限定）
The book, which you’re reading, is mine. 那本书是我的，你正在读那本书。（非限定） 如果以上例子的差别不十分明显，再看下面的例句： I’ve been to London , which is a beautiful city。 我去过伦敦，那是个美丽的城市。
Your father, whom I respect very much, is a kind old man. 你父亲是个很和善的老头，我很尊重他。
Nanjing, where I lived for five years, is very hot in summer. 南京夏天非常热，我在那里生活过五年。
在以上三例当中，定语从句不就能是限定性的。若变成限定性定语从句，其意就成了“我去过那个是座美丽的城市的伦敦。你那个我很尊重的父亲是个很和善的老头。我在那里生活过五年的南京夏天非常热。”言外之意是还有别的伦敦、父亲和南京。
通过这几个例子我们可以看出，专用名词以及世界上独一无二的东西都不能有限定性定语从句。因为它们的意义本身已经非常清楚，不需要对其进行限定。另外，非限定性定语从句的先行词还可以是整个主句所表达的意义。
如：He did well in the physics exam, which surprised me. 他物理考得很好，这使我很吃惊。
（学地道的英语有两个重要的练习方法：parallel writing, and reverse translation，即平行写作和逆翻译。所谓平行写作，就是模仿英语的句子写类似的句子。而逆翻译就是先把英语译成汉语，或根据汉语的译文，再把汉语翻译成英语，再把英语译文同原文比较，分析差异。这两种方法能避免汉语式英语。） He did well in the physics exam, which surprised me. 他物理考得很好，这使我很吃惊。
请把这句话逆翻译。有的同学会翻译为：He did well in the physics exam, this surprised me. 这句话错在什么地方呢？错在句法。这句话有两个主谓结构，是两个并列的分句，但没有连词（this 是代词），这就成了串句。
再如：He’s very particular about wording, which I am not. 他很咬文嚼字，而我不。
I said nothing, which made her angry. 我什么也没说，这使她很生气。
Tom didn’t go to the show, which was a pity. 没去看演出，这很遗憾。 注意各个关系词的用法：
1．指人的关系代词：who, whom, whose, that 的用法： （1）作主语（who, that ）
Those who are going to play in the match are to meet at the gate at 1:30 after lunch.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
那些参加比赛的人午饭后1：30在大门口集合。
在本句中，先行词是those；关系代词who引导定语从句，同时代替先行词在从句中担任动词are going to play 的主语。
The man who/that is talking with Mr. Wang is a famous doctor. 正在和王先生说话的那个人是一个有名的医生。
在本句中，先行词是the man;关系代词who/that引导定语从句，同时代替先行词在从句中担任动词is talking的主语。
这个复合句可以还原成两个句子：The man is a famous doctor. He is talking with Mr. Wang. （2）作宾语包括作介词宾语（whom, that ）。此种情况下的关系代词可以省略； This is just the man(whom/that) I want for the job.这正是我要的做这份工作的人。
在本句中，先行词是the man；关系代词whom/that 引导定语从句，同时代替先行词在从句中担任动词want 的宾语。
Is he the manager (whom/that) you are looking for? 他是你在找的那位经理吗？
（3）当关系代词紧跟介词作介词宾语时，不能用that，也不能省略，
如：The book from which I got a lot of useful information was written by a famous scientist. 我从中得到许多有用信息的那本书是一位著名科学家写的。 Who is the boy with whom you were talking a moment ago. 你刚才和他说话的那个男孩是谁？
I know the young couple from whose house the music is coming.
但是当介词放在从句末尾时，作为介词宾语的关系代词可以用that 并且可以省略。 如上头两句可改为：
The book (that /which) I got a lot of information from was written by a famous scientist. Who is the boy (that/whom) you were talking with a moment ago? 2．指物的关系代词which和that的用法： （１）作主语
This is the instruction manual which/that tells you how to operate the computer. 这是那本教你如何操作计算机的说明手册。
（２）作宾语包括作介词宾馆。此种情况下的关系代词可以省略： The chair (which /that) you broke yesterday is now being repaired. 你昨天弄坏的那把椅子现在正在修理。
The film (which/that) I saw last night was about a soldier who fought in WWII. 我昨天晚上看的那部电影是关于一个在二战中打过仗的士兵的。 （本句有两个定语从句。）
This is the bike for which I paid $ 100. 这就是我花了100美元买的那辆自行车。
The car(which/that)he went in was a black Cadillac. 他坐在里面走了的那辆汽车是一辆黑色的卡迪拉克。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
The accounts of the company, (which/that) I’ve been paying great attention to, are in balance. 我一直非常注意的公司账目，是保持平衡的。
3．whose 和of which 指代人或事物，作定语。of which 可用whose 代替；
The car whose lights (of which the lights/the lights of which) were all broken was my father’s. 那辆所有的灯都破了的汽车是我父亲的。
例：His house of which the windows (the windows of which /whose windows) were all broken was a depressing sight.
他那所有窗户都坏了的房子真是目不忍睹。
That is the book whose cover (of which the cover/the cover of which ) was broken. 这就是那本封皮破了的书。
4．关系代词的格应与它在从句中充当的成分一致。特别要注意插入语，
如：Peter is the one who everybody believes will fail to bring off the contract. Peter 是那个人人都认为不能完成合同的人。（everybody believes 是插入语）
At the election I voted for the man whom I believed to be the most suitable. 在选举的时候我投了我认为最合适的那个人的票。
5．关系代词作从句的主语时，从句的动词必须和先行词的人称和数一致： 例：These are the operating instructions that/which are written in English 。 这就是用英文写成的使用说明。
Are you staying at the white house which/that is newly completed and which /that has 15 bedrooms, 3 kitchens and 4 toilets?
你是住在那幢刚刚竣工、有15个卧室、3个病房和4个卫生间的白色房子里吗？ So far as I know, there are many VIPs who are going to attend the reception. 就我所知有很多达官贵人将出席这个招待会。
6．非限定性定语从句不用that，只用who（whose, whom）和which代表人和物； 例：Her brothers, both of whom work in America, ring her up every week。 她的兄弟们？？两个人都在美国工作？？每个星期都给她打电话。
The buses, most of which were already full, were surrounded by an angry crowd， 那些公共汽车？？大多已经坐满了人？？被一群愤怒的人围着。
That tower block, which cost five million dollars to build, has been empty for five years. 那个塔楼空着已经5年了。建它花了500万美元。
Cricket, which I know very little about, is a very popular sport in England。 板球是英格兰非常流行的体育活动，我对它知之甚少。
The accounts of the company ,which I’ve been paying great attention to, are in balance. 公司的账目是保持平衡的。我一直非常注意这些账目。 7．关系副词（=介词+关系代词）： 关系副词 when(=at / on / in / during which) 先行词 时间名词 在从句中的作用 时间状语 说明 非正式文体中，有时用that代替关系副词 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
where(=in / at which) why=(for which) 地点名词 只有reason 地点状语 原因状语 例：I shall never forget the day when (=on which) we first met. 我永远也不会忘记我们第一次见面的那一天。
The rain came at a time when (=at which) it was not needed. 雨下得不是时候。
This is the computer where (=by/on which) he has stolen top-secret documents. 这就是他用来盗窃绝密文件的计算机。
Here is the place where (=at which) the murder took place. 这就是谋杀发生的地方。
He didn’t give any reason why (=for which) I had been fired. 他没给任何解雇我的理由
This is the house in which (=where) my parents used to live. 这就是我父母以前住过的房子。 注意事项：
（1）在非正式场合， that有时可用来代替关系副词或相当于关系副词的“介词+which”，而且经常全部省略，
如：In all the years that (=when/during which) I was at collage 在我读大学的那些年里
the reason that(=why/for which)he is not happy 他不高兴的理由
The direction(that)(=in which )the heavenly bodies move can’t be changed. 天体运行的方向是不可改变的。
He is unpopular because people don’t like the offensive way (that)(=in which) he talks. 他不受欢迎的原因是他说话的方式让人讨厌。 （2）是用关系代词还是用关系副词：
关系词（包括关系代词和关系副词）是学习英语定语从句的关键。用关系代词还是用关系副词，一要看关系词在从句当中作什么成分；二要看关系词所代表的是人、物、时间、地点还是原因；三要看所引导的是限定性定语从句还是非限定性定语从句。所以同样的先行词会有不同的关系词，这是因为关系词在从句当中担当的作用不同而决定的。
如：This is the room where/in which we’ll celebrate the New Year. 这是我们将要在里面庆贺新年的房间。（充当地点状语）
This is the room(that /which)we’ll celebrate the New Year in. 这是我们将要在里面庆贺新年的房间。（充当介词宾语，可省略。）
This is the room which /that will be used for the celebration of the New Year. 这是那个将要被用来庆贺新年的房间。（充当主语）
This is the room (which/that) we’ll use for the New Year dinner party. 这是我们将要用来举行新年晚宴的房间。（充当宾语，可省略。）
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
The reason (that /which) he had given was not sound enough. 他给的理由不够充分。（充当宾语，可省略）
The reason why/for which he had done that was not sound enough. 他做那件事的理由不够充分。（充当原因状语） This is the house where she lives.这是她住的房子。
【比较：This is the house (that/which) she has bought. 这是她买的房子。This is the house that/which I’ve told you is extremely expensive.这就是我和你说过极其昂贵的那幢房子。】 I met him in the year when I was first in Xi’an. 我刚到西安的那年遇到了他。
That is the reason why he did not come that morning. 那就是那天上午他没来的原因。
（3）定语从句中的时态。如果主句是一般将来时或过去将来时，从句的动作与主句的同时发生，那么该从句要用一般现在时表示一般将来时、用一般过去时表示过去将来时。 例：Anyone who/that touches the wire will get an electric shock. 任何碰这根电线的人将受到电击。（不用will touch） I would give her anything that she asked for. 她要什么我就给她什么。（不用would ask）
The first person who/that opens the door will get a shock. 第一个开门的人将被吓一跳。（不用will open）
There will be a special price for anybody who orders a suit in the next two weeks. 任何人在下两周内定做套装都将享受优惠价格。（不用will order）
但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，
如：Those who will go abroad for training next year will start learning English tomorrow. 那些明年出国受训的人员，将从明天开始学习外语。
注：①先行词有最高级形容词修饰时，常用that，而不用which： 例：Edison was one of the greatest inventors that ever lived. 爱迪生是曾经有过的最伟大的发明家之一。 This is the best film that I’ve ever seen. 这是我曾经看过的最好的电影。
She was the greatest woman that/who has ever lived. 她是曾经有过的最伟大的女人。
②先行词有the same, the very, the first, the last, all, no, the only, much, little, none, any, every等时，常用that, 而不用which：
例：He was the first man that we saw in the village. 他是我们在那个村子里看到的第一个人。 There is little that is interesting. 没什么令人感兴趣。
I still remember the first time that we met.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
我仍然记得我们第一次见面的时候。 I’ll do anything (that) I can to help you. 我将尽一切可能帮助你。
Everything that can be done has been done. 能做的一切都做了。
God bless this ship and all who sail in her. 愿上帝保佑此船和所有乘此船航行的人。 All that I can say is thank you very much. 我能说的是（千言万语变成一句话）：非常感谢你。 ③当先行词既有人又有物时，用that，不用which，
如：We were deeply impressed by the workers and their working conditions that we had visited. 我们参观过的工人及他们的工作条件留下了深刻印象。
We listened to him talk about the men and books that interested him。 我们听他谈论他感兴趣的人物和书籍。 ④在same和such之后，定语从句用as引导，
如：Let’s discuss only such questions as concern us. 让我们只讨论与我们有关的问题。
I’ve never heard such stories as he tells. 我从来没听说过他讲的这种故事。
I shall be surprised if he does this in the same way as I do. 如果他做这件事的方法和我一样，那就奇怪了。 She works in the same office as I do. 她和我在同一个办公室工作。
She wears the same kind of clothes as her sister does. 她姐妹俩穿同样的衣服。
He’s wearing the same dress as he wore at Mary’s wedding. 他穿着与他在Mary的婚礼上穿的一样的衣服。 This is the same watch as I have lost. 这块表和我丢的那块一样。
I’ve never seen such kind of people as they are. 我从来没见过像他们这样的人。
I’ve never seen such kind people as they are. 我从来没见过象他们这样厚道的人。 I want the same shirt as my friend’s. 我要一件跟我朋友一样的衬衫。
Such machines as are used in our workshop are made in china. 我们车间使用的这种机器是中国制造的。
但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
注：④在same和such之后，定语从句用as引导， 偶尔，the same 后面也用that，
如：He’s wearing the same suit that he wore at Mary’s wedding. 他穿着与他在Mary的婚礼上穿的一样的衣服。 She works in the same office that I do. 她和我在同一个办公室工作。
This is the same watch that I have lost. 这块表和我丢的那块一样。
as 引导非限定性定语从句即可放在主句之前，也可放在主句之后，用来修饰整个句子。当as在从句中作主语时，后面常接下列句型。如：as is known, as is said, as is reported as is announced 等。 例如：As we all know, Mr. Wang is a good teacher. As is known to all, the earth revolves round the sun. He is tired, as you can see.
As I expected, he didn’t believe me.
As 引导非限定性定语从句时与which的区别：当主句和从句语义一致时，用as；反之，用which。 如：He made a long speech, as was expected. He made a long speech, which was unexpected.
Tom drinks a lot every day, which his wife doesn’t like at all.
（3）但是，如果从句和主句的动作在将来不同的时间发生，则两部分都要用来将来时，
注：⑤在“介词+关系代词”的结构中，也可用复杂介词，如：by means of （用，依靠），as a result of （作为结果）等：
例：I have three children, one daughter and two sons, all of whom graduated from the same university .
我有三个孩子：一个女儿、两个儿子，他们都毕业于同一所大学。
The police, in whom I have great confidence, are trying to find out who did it. 我对警察有极大的信心，他们正在努力寻找是谁做的这件事。 This is the part of the river in which I like to swim. （in which=where）
我喜欢在这条河里面游泳，这就是（我喜欢游的）那个地方。 The man from whom you bought the house is my uncle. 你从他那里买下房子的那个人是我叔叔。
This is the desk by means of which he jumped over the wall. 这就是他用来跳过墙去的那张桌子。
She was running a fever, as a result of which she failed in the exam. 她当时正发烧，所以考试失败了。
He is the man from whose house the picture was stolen. 他就是那个家里的画被偷了的人。
注：⑥一个先行词后面可以跟一个以上的定语从句，这种现象叫双重关系从句：
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
例：Here are some words which are often used but which are very confusing. 这里有些常用但非常混乱的词。
He is the only person that I can find who is able to solve the problem. 他是我能找到的唯一解决这个问题的人。
八、名词性从句
在主从复合句中，从句可以充当主句的主语、表语、宾语或同位语。由于在多数情况下，主语、表语、宾语或同位语这四种句子成分由名词性词类充当，所以，我们把这些作用相当于名词的从句统称为名词性从句，把充当主语、表语、宾语或同位语的从句分别称为主语从句、表语从句、宾语从句或同位语从句。也就是说充当什么成分就叫什么从句。名词性从句由连接词（或关联词）引导。 常用的连接词有： 连接词 whether是否 that（本身无词义） who，whom，whose which哪一个 what什么，所…的 when什么时候，where什么地方 how怎样，怎么，why为什么 疑问词（who, whom, whose, what, which, where, why, when, how）可以引导主语、宾语和表语从句。 它们的特点是：1、疑问词有本身的词义；2、疑问词在从句中担当句子成分，如主语、宾语或状语；3、这种疑问词引导的从句一律用陈述语序，不能用疑问语序。 For example:
Do you know whom they are looking for? 你知道他们在找谁吗？（宾语从句，陈述语序。不能是whom are they looking for?）
I don’t know who did it. 我不知道这是谁干的。（宾语从句。在从句中如果疑问词作主语，其陈述语序和疑问语序一致。）
She asked me where I had been. 她问我到哪儿去了。（宾语从句。陈述语序，不能是where had I been. 直接引语，间接引语。注意这句话的时态。）
Can you tell me when the train will arrive? 你能告诉我火车什么时候到吗？(宾语从句。陈述语序，不能是when will the train arrive. 直接引语，间接引语。)
I don’t know why he hasn’t come yet. 我不知道他为什么还没来。（宾语从句，陈述语序。不能是why hasn’t he come yet.）
He didn’t tell me what you were doing. 他没和我说你在干什么。（宾语从句，陈述语序。不能是what were you doing.）
What you have done might do harm t other people. 你所做过的事情有可能伤害别人。（主语从句。what 作从句的宾语。陈述语序，不能是what have you done. 如果用疑问语序，意思发生了变化，成了“你做了什么？”。）
作用 只起连接词作用，引导从句，在从句中不作任何成分 在从句中分别作主语、宾语和定语 在从句中分别作主语、宾语和定语 在从句中分别作主语、宾语和定语 除了起连接词作用外，还在从句中作状语 研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
I don’t know where he is now. 我不知道他现在在哪里。（宾语从句，陈述语序。不能是where is he now.）
Where he went for his weekend is not known. 不知道他去哪里过的周末。（主语从句，where 作从句的地点状语。陈述语序，不能是where did he go for his weekend.）
Whose fault this is is not important. 这是谁的过错并不重要。（主语从句，whose 作从句的定语。陈述语序，不能是whose fault is this.）
What I want to know is where he has gone for his weekend. 我想知道的是他到哪里度周末去了。（这句话包含两个名词性从句：what I want to know是主语从句，what 在从句中作宾语，从句用陈述语序，不能是What do I want to know. Where he has gone for his weekend 是表语从句，where 在从句中作状语，从句用陈述语序，不能是where has he gone for his weekend.） 下面分述主语从句、宾语从句、同位语从句和表语从句。 A主语从句
1．that 引导主语从句时，that 没有意义，但不能省略。（that 引导宾语从句时可以省略。） For example:
It worried her a bit that her hair was turning gray. 她的头发正在变白，这使她很不安。that引导主语从句，it 作形式主语，that 不能省略。
That she is a rich woman is known to us all. 众所周知，她是个富有的女人。这是that 引导主语从句，that 不能省略。这句话可以改为用it 作形式主语的句型。请同学们改写：It is known to us all that she is a rich woman.）
We didn’t know (that) you had sold your house. 我们不知道你已经把你的房子卖了。这是that引导宾语从句，that 可以省略。注意这句话的时态。
2．从句作主语时，多数情况下由 it 作形式主语，而把主语从句放在后面，尤其是谓语部分（包括宾语）较短的情况下。 For example:
It wasn’t very clear what she meant. 不清楚她是什么意思。 It is important that he should come on time. 他按时来是很重要的。
It is true that that man on the left is a well-known writer here. 左边那个人是本地的一位著名作家，这是真的。这里，第一个that 引导主语从句，是单纯的连词，无词义，不作句子成分。第二个that 是指示代词，作句子成分，是man 的定语。
3．whether 既可以引导主语从句也可以引导宾语从句，但if不能引导主语从句。whether 后面可以加or not, 而if 不能与or not 连用。作介词宾语时不用if. For example:
Whether I knew John doesn’t matter. = It doesn’t matter whether I knew John. 我是否认识约翰没有关系。
Whether or not she’ll come isn’t clear. = Whether she’ll come or not isn’t clear. = It isn’t clear whether …. 她是否来还不清楚。
It all depends on whether we can get their cooperation. 这是主语从句还是宾语从句？it 是形式主语吗？it 是代词，whether 引导的是宾语从句，作介词on 的宾语，不能用if引导。请翻译这句话。这完

全取决于我们是否能得到他们的合作。
I worry about whether I hurt her feelings. 宾语从句，介词宾语，不能用if 引导。请翻译这句话。 She asked me whether/if you were married. 宾语从句，既可以用whether, 又可以用if 引导。注意时态的对应。请翻译这句话。
We haven’t decided whether/if we shall give them aid. I’m not sure whether/if the report is believable. Now let’s do some translation:
现在还很难预测谁会赢得下一届总统选举。
It is still hard to predict who will win the next presidential election. 对于多数公民来说，谁当选总统无关紧要。
Who will become the president doesn’t matter much to most citizens.
这位前总统是否会被判处死刑还有待观察。It remains to be seen whether the ex-president will be sentenced to death.
真可惜，王教授不能出席我们的英语晚会。
It is a pity that Prof. Wang can’t attend our English Evening. 我们需要的是更多的时间。 What we need is more time. B宾语从句
宾语从句
在谓语动词、介词、动词不定式、分词、动名词之后都可以带有宾语从句。某些形容词如sure, happy, glad, certain, pleased 等之后也可以带有宾语从句。
1．that 引导的宾语从句: that 没有意义，在口语或非正式文体中常省略：如： I really feel she’s making a mistake. 我的确感到她正犯错误。 James said (that) he was feeling better. 詹姆斯说他感到好些了。
Hearing that his son was badly wounded, he hurried to the hospital to see him. 听说儿子受了重伤，他急忙赶到医院去看望他。
I suggested that we should go home. 我建议我们回家去。虚拟语气，that 一般不能省略。 2．whether/if (是否)引导的宾语从句：如果要突出“究竟是…还是不…”，常在whether 后面加or not; if 一般不与or not连用。如：
He asked me if/whether I knew John. 他问我是否认识约翰。
Let me know whether you can come or not. 你能来还是不能来，告诉我一声。
3．在think, believe, suppose, expect 等动词的宾语从句中，否定不用在从句中，而是将think 等词变为否定形式。 For example:
I don’t think the film is interesting. 我觉得这部电影没什么意思。
I don’t suppose we are going outing tomorrow. 我认为我们明天不会出去郊游。
4．如果从句作宾语而后面还有补语，为了保持句子的平衡，用it 作形式宾语，而将宾语从句放在句尾。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
常跟这样的复合宾语的动词有：make, find, see, hear, feel, think, consider, regard, take….for granted等。如：
George made it clear that he opposed this project. 乔治已明确表示他反对这个项目。it 代表that 引导的句子，作宾语，clear 是宾语补足语。
They kept it quiet that he was dead. 对他已经死亡的消息，他们秘而不宣。 I took it for granted that you’d stay with us. 我想当然认为你会和我们呆在一起。 C 同位语从句
同位语从句是对名词的内容给予具体、详细的说明。常在后面接同位语从句的名词有fact, news, idea, truth, hope, suggestion, question, problem, doubt, fear, belief等。同位语从句常用的引导词为that,有是也用when, where 等疑问词。如：
The news that the United States was hit by terrorist attacks took the whole world by surprise. 美国受到恐怖主义分子袭击的消息令全世界吃惊。
The idea that you can do this work well without thinking is quite wrong. 你认为不动脑筋就能做好这件工作的想法是完全错误的。
People used to hold the belief that the earth was the center of the universe. 人们曾认为地球是宇宙的中心。
The difficulty lies in the fact that we are short of money. 困难在于我们缺乏资金这个事实。 They have no idea at all where he has gone. 他们一点儿也不知道他去哪儿了。
注意：同位语从句的that 只是引导词，没有其他语法作用，在句子中不作句子成分，不能省略；而定语从句中的that 除了引导定语从句外，还是定语从句的一个成分，在定语从句中作主语或宾语，作主语时不能省略，作宾语时可以省略。如：
The idea that some peoples are superior to others is sheer nonsense. 有些民族优越于其他民族这种想法简直荒谬。（请辨别是同位语从句还是定语从句。）（同位语从句）
The idea that he proposed at the meeting is sheer nonsense. 他在会议上提出的这个想法简直荒谬。（请辨别是同位语从句还是定语从句。）（定语从句）
No one is happy with the fact that he found out. 没有人对他发现的事实感到高兴。（请辨别是同位语从句还是定语从句。）（定语从句）
No one is happy with the fact that he will become their boss. 没有人对他将成为他们的老板这一事实感到高兴。（请辨别是同位语从句还是定语从句。）（同位语从句） D表语从句
表语从句位于主句的连系动词之后，在非正式文体中引导词that可以省略。如： That’s not what I want. 那不是我要的。 That’s why I have come. 那就是我为什么来了。
My opinion is that things will improve. 我的意见是事情会好起来的。
One advantage of solar energy is that it will never run out. 太阳能的一个优点是永远也不会枯竭。 The truth is that he didn’t really try. 实际情况是他没有真正努力。
The problem is who is to pay and when we can start. 问题是谁来付帐、我们又何时开始。 The fact is that he didn’t notice the car until too late. 事实是他注意到车时已经太晚了。

What I want to know is where we shall go and whether she will join us. 我想知道的是我们要去什么地方以及她是否加入我们。
表语从句位于主句的连系动词之后，在非正式文体中引导词that可以省略。如：

What I want to know is where we shall go and whether she will join us. 我想知道的是我们要去什么地方以及她是否加入我们。
此外，表语从句还可由as if （好像）引导。如： It looked as if it was/were going to rain. （虚拟语气） Now let’s do some translation: 这就是她昨天请一天假的原因。
That is why she had a day off yesterday. 我的想法是，个人的权利应该得到充分尊重。

that 引导的名词性从句还可以用在一些形容词后面。这种句型一般都用人作主语，所用的形容词都是表示思想状况或感情色彩的形容词，如certain, sure, positive, afraid, convinced, anxious, disappointed, worried, glad, happy, sorry, amazed, surprised, aware, doubtful, confident等等。如： I am sure/certain that he’s at home now. 我肯定他现在在家。
He became angry that you made the same mistake. 你犯了同样的错误，他生气了。 He remains confident that he will win. 他仍然自信他会赢 She is aware that I can’t help her. 她知道我帮不了她的忙。 I am glad that you’ve come. 你来了我很高兴。
He appeared/seemed surprised that I said “no”. 我说不，他似乎很吃惊。 I am afraid that I can’t promise you anything. 恐怕我不能向你保证什么。
We were rather disappointed that you were not able to come yesterday. 昨天你没能来我们有点失望。
I am a bit worried that she will not be able to make it. 我有点担心她做不成这件事情。 what 从句的小结

3．引导让步状语从句，等于“不管什么…”。注意状语从句的语序。如：
Do what she would, she could not invent a reason for not going. 不管她会做什么，她都编不出不去的理由。状语从句把实义动词放在句首，句子倒装。＝No matter what she would do, …
Come what may, you’ll always keep it secret. 无论怎样，你都要保守秘密。＝No matter what may come, ….
Jack has made up his mind that, come what might, he would stay there. Jack已经拿定主意，无论如何他也要呆在那里。＝…no matter what might come, …
Say what he will, in his heart he knows that he is wrong. 不管他怎么说，内心里他知道自己错了。= No matter what he will say.
九、强调句
英语的强调主要有两种：一是强调非谓语（包括主语、宾语、状语等）；二是强调谓语动词。 （一）强调非谓语
其基本句型是：“It + is/was + 被强调的成分 ＋ that/who + 其她成分”。It 没有实意，只起语法作用，引导被强调的部分。当被强调的是人时，可用who(m)/that, 其他情况用that。 例如：
It was I who/that met Jack yesterday. 是我昨天碰到了Jack. （强调主语）
It was Jack that/whom I met yesterday. 我昨天碰到的是Jack。 （强调宾语）
It was yesterday that I met Jack. 是昨天我碰到了Jack. （强调时间状语）
这几句话复原为非强调句就是：I met Jack yesterday.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
It is people, not things, that are decisive. 决定的因素是人，不是物。 （强调主语）
It is because the book is very important for my present job that I bought it. 是因为这本书对我目前的工作很有用，我才买了它。 （强调原因状语）
It was in the supermarket that I gave the book to him. 是在那家超市里我给了他那本书。（强调地点状语）
1．强调主语：
It was John who broke the window. 是John打破了窗子。 原句：John broke the window.
It is this overpass that will be pulled down. 将被拆掉的是这个天桥。 原句：This overpass will be pulled down.
It is the people who/that are really powerful. 真正有力量的是人民。 原句：The people are really powerful. 2．强调状语： （1）强调时间状语。 例如：
It was at that moment that he changed his mind. 是在那一刻他改变了主意。
It is every day that Professor Smith goes swimming. 史密斯教授是天天去游泳。
It was not until Saturday that he began to prepare for the examination. 他直到星期六才开始为考试作准备。
注意：这句话的原句是He did not begin to prepare for the examination until Saturday. 变成强调时间状语，注意 “not” 位置的变化。 （2）强调地点状语。 例如：
It was in the library that I met Jack yesterday. 是在图书馆我昨天碰到了Jack.
原句：I met Jack in the library yesterday.
It might have been on the bus that I lost my purse. 可能是在公共汽车上我丢失了钱包。
原句是：I might have lost my purse on the bus. 强调地点状语，也可改为：It was on the bus that I might have lost my purse.
It was under the tree that I was sitting then. 当时我正坐在那棵树下。 3．强调宾语。 例如：
It was Tom’s bike that she borrowed, not mine.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
她借的是Tom的自行车，不是我的。
It is his dog that he’s sold, not his car. 他已卖掉的是他的狗，不是车。 It was a cat that your dog was running after. 你的狗追的是只猫。 4．强调宾语补足语： 例如：
It was wonderful that we considered his plan. 我们认为他的计划是绝妙的。
It is Lincoln that they named the aircraft carrier. 他们把那艘航母命名为林肯号。
It was captain that the team chose him. 那个队选他当的是队长。 It was white that Tom was painting the fence. 汤姆当时正在把篱笆涂成白色的。
这句话的原句是： Tom was painting the fence white.
类似的结构有：color the sun red, color the tree green, paint the wall pink 等，这里，颜色作宾语补足语。
It is a fine player that we believe Jane. 我们相信Jane是一个出色的选手。
It is the Buckingham Palace that the British Queen’s office building is called. 英国女王的办公大楼被称作白金汉宫。
It is Cadillac that this car is named. 这辆车被命名为卡迪拉克。 （二）强调谓语动词
用“助动词do ＋ 动词原形”来强调谓语动词。
注意：谓语动词只有两种时态能强调，即一般现在时和一般过去时。在一般现在时中，do有人称的变化，第三人称单数用does，一般过去时do 变成did。其他时态的强调通过重读谓语动词来体现。 例如：
You’re quite wrong？she does like you. 你错了，她真的喜欢你。 Do come in. 快进来。
用“助动词do ＋ 动词原形”来强调谓语动词。 1．强调一般现在时动词谓语： 例如：
I work hard. → I do work hard. She loves you. → She does love you.
My father smokes a lot. → My father does smoke a lot. 2．强调一般过去时动词谓语： 例如：
I called you in the morning. → I did call you in the morning. I attended the meeting yesterday.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
→ I did attend the meeting yesterday. I handed in the paper yesterday. → I did hand in the paper yesterday. He wrote a letter to me yesterday. → He did write a letter to me. He came to see you yesterday.
→ He did come to see you yesterday. （三）其他表示强调的方式 1．把要强调的部分放在句首： 例如:
That film？what do you think of it? Asleep, then, were you?
2．用某些特殊的词来表示强调，如really, certainly, definitely, very等。在口语中，such 和so 都常用于强调句。 如：
Thank you so much. It was such a lovely party. I really enjoyed it.
This is the very book that I am looking for. 我要找的就是这本书。
十、倒装句
英语句子的语序一般是固定的：主语在前，谓语在后，这叫陈述语序。谓语的全部或一部分（助动词或情态动词）放在主语之前的现象称为倒装。倒装有两种情况：语法倒装和修辞倒装。因为语法结构而必须倒装的，叫语法倒装；为达到某种修辞目的而倒装的，叫修辞倒装。我们学习倒装的主要目的是增加对英语句式多样性的认识，以便在写作和口语中使用，这也是我们学习英语语法的主要目的。 （一）语法倒装
1．一般疑问句和特殊疑问句要倒装 例如：
Shall I open the door? 要我开门吗？ Are you cold? 你冷吗？
Can you read this poem in German? 你能用德语朗诵这首诗吗？ Which of the pictures do you like best? 你最喜欢哪张画？ How are you getting along? 你目前怎么样？ When will there be lasting peace in the world? 什么时候世界上才能有持久的和平？
2．There be 句型当中。There be 句型表达的意思是：“某处有….”。这个句型的主语在谓语动词后面，因此这是倒装语序。 例如：
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
There are not many people who want to read this book. 想看这本书的人不多。
There once lived a pack of wolves in this cave. 在这个洞里曾经住过一群狼。
There happened to be a taxi parked at the gate. 碰巧门口停着一辆出租车。
There is going to be a change in our arrangement. 我们的安排将有一个变化。
3．当连词as 表示“虽然、尽管”引导让步状语从句时，句子要倒装，as 相当于though,可以替换。 如：
Small as/though the atom is, we can smash it. 尽管原子很小，我们可以击碎它。
Tired as/though he was, he went on working. (=Although he was very tired, he went on working.) 虽然他很累，他还是接着工作。
Cold as/though it was, we went out. 虽然天气冷，我们还是出去了。 Child as/though she is, she knows a great deal. 她虽然是个孩子，但她懂得很多。
Teacher as he is, he knows little about teaching. 尽管他是个老师，但不懂什么教学。
Pilots as he claims he is, no one has ever seen him fly a plane. 尽管他声称是个飞行员，但谁也没见过他非飞机。
注意后四句是可数名词单数作表语并提前，习惯上不用冠词。
4．虚拟语气条件从句中的if 被省略时，要把从句中的were, had 或should 移到主语之前。（if 的省略、倒装只限于从句中有were, had 或should这三个词时。） 例如：
If I had been in your place, I wouldn’t have given it up so early. =Had I been in your place, I wouldn’t have given it up so early. 如果我在你的位置，我不会这样早放弃。
If he were to succeed, the sun would rise from the west. ＝Were he to succeed, the sun…. 如果他能成功，太阳就会从西边出来。
If you should be asked about this, say that you know nothing. =Should you be asked about this, say…… 如果有人问起你这件事，你就说你什么也不知道。
Were there no air or water, there would be no life on the earth. 如果没有空气和水，地球上就不会有生命。
Had you been more careful, you might have avoided the mistake.

如果你再细心点，本来事可以避免这个错误的。
5．以so开头的，表示“也一样”，“也这样”的句子要倒装。So 用于肯定句，代替上文中的形容词、名词或动词，通常指前面所说的肯定情况也适用于其他人或物。结构是“so + be (do, have 其他助动词或情态动词)＋主语”。 如：
Production is going up, so is the people’s standard of living. 生产不断发展，人们的生活水平也一样。
Society has changed and so have the people in it. 社会变了， 社会上的人也变了。
Coal is under the ground, and so is oil. 煤在地底下，石油也是。 He saw it, and so did I. 他看见了，我也看见了。
They can swim now, and so can we. 他们现在能游泳，我们也能。 We must start for the work-site now. So must you. 我们该动身去工地了，你们也该去了。
注意：如果只是对前句的内容表示同意，则不要倒装。 如：
It was hot yesterday. ？So it was! 昨天很热。是的。 He works very hard. ？So he does. 他工作很努力。是的。 Tomorrow will be Monday. ？So it will. 明天星期一。对。 翻译下列句子：
1）我会说英语。我弟弟也会。
→I can speak English. So can my brother. 2）他们上星期日到颐和园去了。我们也去了。
→They went to the Summer Palace last Sunday. So did we. 3）他去过长城。我也去过。
→He has been to the Great Wall. So have I. 4）她喜欢教英语。我姐姐也喜欢。
→She enjoys teaching English. So does my sister. 5）你说他很努力，对，他确实很努力，你也一样。 →You say he works hard. So he does, and so do you.
注意：在so…..that…..结构中，如果so 在句首，通常也用倒装结构。 例如：
So easy is it that a boy can learn it. 那很容易，小孩子都能学。
（原句是：It is so easy that a boy can learn it.）
So rapidly did he speak that we could hardly understand him clearly. 他说得很快，我们简直听不清楚。
（原句是：He spoke so rapidly that we could hardly understand him clearly.）

6．以neither与nor开头的句子，表示“…也不”时，句子倒装。Neither 与nor 意思相同，可以互换。Neither, nor 用于否定句，通常指前面所说的否定情况也适用于其他人或物。结构是：Neither (nor) + be (do, have, 其他助动词或情态动词) ＋主语。 例如：
I won’t do such a thing. Nor/Neither will anyone else. 我不会做这样的事，别人也不会。
The first one wasn’t good and neither was the second. 第一个不好，第二个也不好。 I won’t go there. Neither will she. 我将不去那里。她也不去。 翻译练习：
1）我不知道他住哪儿。她也不知道。
I don’t know where he lives. Neither does she. 2）我不知道这两个句子的区别。？他们也不知道。
I don’t know the difference between these two sentences. Nor do they. 3）我昨天晚上没有写作文。魏芳也没写。
I didn’t write my composition yesterday evening. Neither did Wei Fang. 4）学生们不在教室里。老师也不在。
The students were not in the classroom. Nor was the teacher.
7．以here, there, now, then 等副词开头的句子中。习惯上用一般现在时（除以then开头的句子用过去时）。 例如：
There comes the bus! 汽车来了。 There goes the bell. 铃响了。 Now comes your turn. 该轮到你了。
Then came a new difficulty. 接着来了个新难题。
Then followed three days of heavy rain. 后来连着下了三天大雨。 Up went the plane. 飞起来了飞机。
Our rushed a cat from under the bed. 从床底下窜出一只猫。 Here is a letter for you. 这儿有你一封信。 注意：在这种句型中，如果主语是代词时就不倒装。 例如：
Here you are. 给你。 There he comes. 他来了。 Here it is. 这就是。 8．在表示祝愿的句子中。 如：
May you have a pleasant trip. 祝你旅途愉快。
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
（二）修辞倒装
1．在以never, hardly, scarcely, rarely, barely, seldom, not only, not until, nor, little, nowhere, hardly….when, no sooner….than, by no means, under no circumstances 等开头的句子中，主谓要倒装。这些都是表示否定或半否定意义的词或词组。 例如：
Never have I come across such a difficult problem. 我还从没有遇到过这样困难的问题。
Seldom do I read such magazines. 我很少读这种杂志。 No sooner had they left than the bus arrived. 他们刚走，公共汽车就来了。
Never before have I met him. 我以前从未见过他。 Hardly did I think it possible. 我想这几乎不可能。
Not only should we not be afraid of difficulties, but we should try our best to overcome them. 我们不但应该不怕困难，而且要尽最大努力克服困难。 Not until midnight did it stop raining. 直到半夜雨才停。
（正常语序是：It did not stop raining until midnight. 注意not位置的变化）
Very seldom do you find that two clocks or watches exactly agree. 你很难发现两个钟或表的时间完全一样。
By no means will this method produce satisfactory results. 这种方法决不会产生令人满意的结果。 翻译练习（使用倒装结构）：
1)我从来没有读过这么一本有意思的书。 Never have I read such an interesting book. 2)她一点也不知道会发生什么事。 Little does she know what may happen. 3)我简直不相信这是真的。
Hardly could I believe it (to be) true. 4)我刚到家，就下起大雨来了。
No sooner had I reached home than it began to rain heavily. 5)最近我很少见到她。
Seldom have I met her recently.
6)爱因斯坦不仅是世界闻名的科学家，而且还是一个相当不错的小提琴家。
Not only was Einstein a world famous scientist, but also a fairly good violinist. 7)直到战争结束，他才回家。
Not until after the war did he return home.
（正常语序是： He did not return home until after the war.） 8)在任何情况下，我们都不应该做违反人民意愿的事。
Under no circumstances should we do anything against the will of the people.
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
2．在以“only+状语”开头的句子中，主谓要倒装。这里only后面必须跟有它修饰的状语或状语从句，这是关键。否则就不倒装。 例如：
Only after the war was over was man able to realize the wickedness of the atomic bomb. 只是在战争结束后人类才意识到原子弹的可恶。 （注意：only 引导的状语从句不倒装，主句倒装。） Only then did I realize the importance of English. 只在那时我才意识到英语的重要性。
Only in this way can we improve ourselves. 只有用这种方法我们才能不断提高自己。 Only after you finish it can you leave. 只有结束它以后，你才能离开。（主句倒装）
注意：Only 如不在句首，或only 修饰的不是状语，则不倒装。 如：
The contract was signed only after bitter negotiations. 只有在艰苦的谈判以后，合同才得以签署。 （改成倒装：Only after bitter negotiations was the contract signed.） Only the senior staff are allowed to use this room. 只许资深的职员使用这个房间。
Only five passengers survived the accident. 事故中只有五位旅客生存了下来。
3．用于以表示处所、声音等意义的副词开头的句子。用表示运动的不及物动词（如go, come, rush, fly 等）作谓语时，为了表示生动，可将某些副词放在句首，谓语动词放在主语之前，形成倒装结构。 例如：
Away flew the birds. 鸟儿飞走了。 Out went the children. 孩子们出去了。 Down came the rain. 下起大雨来了。
Bang went the firecracker. 爆竹砰的一声响了。 The door burst open and in rushed a stranger. 门突然开了，一个陌生人冲了进来。
4．用倒装来避免头重脚轻，使句子显得平衡。这主要是因为主语过长或强调表语或状语。 例如：
At the center of the big room over there is a table that is made of wood which is imported from Brazil of South America.
在那边那个大房子的中央有一张用从南美洲的巴西进口的木头做成的桌子。
（正常语序：A table that is made of wood which is imported from Brazil of South America is at the center of the big room over there. 这句话主语和谓语间隔太长，不平衡。）
Still wider will be the use of radar, which plays a very important role in our national defense. 雷达在我们的国防事业中起着非常重要的作用，它的用处将会更广泛。

（正常语序：The use of radar, which plays a very important role in our national defense, will be still wider. 主语和谓语间隔太长，不平衡。）
Written in English on the blackboard were these words: “Merry Christmas!” 在黑板上用英语写着这么几个字：“圣诞快乐！”

Inside the pyramids are the burial rooms for the kings and queens and long passages to these rooms. 金字塔里面是国王和王后们的墓穴和通往墓穴的长通道。 5．其他用法
倒装还可用在强调表语和宾语的句子中。把表语和宾语提到主语前。 如：
Such was Albert Einstein, a simple man of great achievements. 爱因斯坦就是这样一个取得了伟大成就的单纯的人。 Such was the story he told me. 这就是他给我讲的故事。
Happy is he who devotes himself to the cause of communism. 十一、It用法详解
it 在英语中的意思较多，用法较广，现总结如下。 （一）it作句子的真正主语

动词不定式、动名词短语起、从句在句子中起主语作用，而这一部分用词较多时，可以用it作为形式主语，放在句首代表其后所说的事实上的、真正的主语，而把真正的主语放在后面。 1．It +谓语＋动词不定式。It 作形式主语，动词不定式作真正的主语。 例如：
It is difficult to climb a mountain. 爬山是很艰难的。
It’s a good habit to do morning exercises. 作早操是个好习惯。
It’s important to do proper memory work in the study of a foreign language. 在学习外语时适当地做一些有助于记忆的练习是很重要的。 It is right to do so. 这样做是对的。

It is dangerous playing with fire. 玩火是危险的。 It is no use learning without thinking. 学而不思则罔。
It’s useless arguing with a silly boy. 和笨孩子争论是没有用的。
3．It ＋谓语＋名词性从句。It 作形式主语，以that 引导的名词性从句是真正的主语。 例如：
It is a pity that you didn’t see such a good film. 你没看这么好的电影，真可惜。
It is certain that we shall succeed. 我们一定会成功。 It is strange that nobody knows where he lives. 真奇怪，谁也不知道他住在哪里。 （It is strange that…后面可用虚拟语气。
如：It is strange that he should have made such a mistake. 他居然犯了这样一个错误，真奇怪。
It is strange that nobody should know where he lives. 居然没有人知道他住在哪里，真奇怪。）
It is said that the plane will take off at ten tomorrow morning. 据说飞机明天上午十点起飞。 （三）it作形式宾语
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
it 作形式宾语，代表其后所说的真正的宾语。真正的宾语是以that 引导的名词性从句或不定式短语。例如： I consider it wrong that you Chinese students learn English without comparing it with your own language.
我认为你们中国学生学习英语，不和你们自己的语言比较是不对的。 I find it not so difficult to learn a foreign language. 我发现学习一门外语不那么困难。
I remember I made it clear to you that I was not coming. 我记得向你明确表示过我不来。
They want to make it clear to the public that they are doing an important and necessary job. 他们要向公众表明，他们在做一件重要而又必要的工作。 （四）it 用于强调结构
在表示强调的结构中，it 可用作先行代词，这种结构的句型如下：It +is/was +被强调的部分＋that +其他部分。如果强调的部分是人，可用who, whom 代替that. 例如：
Professor Wang teaches us English every Monday afternoon. 王教授每星期一下午教我们英语。
强调主语：It is Professor Wang who teaches us English every Monday afternoon. 强调间接宾语：It is us whom Prof. Wang teaches English every Monday afternoon. 强调直接宾语：It is English that Prof. Wang teaches us every Monday afternoon. 强调状语：It is every Monday afternoon that Prof. Wang teaches us English. It was here that I first met him. 这就是我初次与他见面的地方。 （强调状语）

反意疑问句相当于“对不对？”“好不好？”“行不行？”，用yes或 no 回答。由两部分组成，前一部分是陈述句，后一部分是附加疑问短语，中间用逗号隔开，所以反意疑问句又叫附加疑问句。通常的形式是：肯定的陈述句＋否定的附加疑问，或否定的陈述句＋肯定的附加疑问。 如：
He studies English, doesn’t he? He doesn’t study English, does he? They are from America, aren’t they? They are not from America, are they? 反意疑问句的主要形式：
1．如果主句是be或其他助动词（如can, shall, will 等），其反意疑问句用同一助动词。 如：
We are late, aren’t we?
You haven’t met my wife, have you? He can drive a car, can’t he?
They used to have difficulty in just making ends meet, didn’t (usedn’t) they? You’d better eat with knives and forks, hadn’t you?
2．如果主语带有seldom, hardly, never, rarely, few, little等否定词或半否定词时，因为主句本身具有否定意义，附加疑问部分的动词用肯定式， 如：
We seldom go to the cinema, do we? Sue almost never worked, did she?
3．如果主句部分是 “I am…”结构，由于”am not” 没有相应的缩略形式，附加疑问部分一般用aren’t I 代替。 如：
I am your friend, aren’t I? I’m late, aren’t I? I am a student, aren’t I?
在祈使句中的附加疑问部分一般用will you, won’t you. 4. 在祈使句中的附加疑问部分一般用will you, won’t you. 如：
Sit down, will you?
Have some tea, won’t you? Open the window, won’t you?
这种句子可以理解为: Will you do something? 如:Will you open the window?

注意：否定的祈使句之后，只能用will. 如：
Don’t forget, will you?
Don’t make so much noise, will you?
5．以Let’s… 开头的祈使句，肯定的用shall we? 否定的用all right? 或OK?, 如： Let’s go back to our seats, shall we?
Let’s not have hot food this time, OK? (all right?) 这种句子可以理解为：Shall we (do something?),
如:Shall we go back to our seats.这样有助于理解和记忆。
注意：Let’s 与Let us 的区别：Let’s包括听话人在内，应用shall we, 而Let us 不包括听话人在内，表示“请你让我们…”，要用will you. 如：
Let’s watch the news on TV, shall we? （表示建议） Let us watch the news on TV, will you? （表示请求）
6．主句是I suppose, I think, I believe等时，附加疑问部分则往往与that 从句中的主语和谓语动词保持对应关系，但要注意否定的转移。 如：
I suppose that you know the meaning of the word, don’t you? （这句话明显是要问“你是不是知道？”而不是问“我是不是这样认为？”） I don’t think that you have read the book, have you?
7．当主句的动词have 表示“拥有”时，附加疑问既可用have, 也可用do, 如：
You have a color TV set, haven’t you/don’t you?
当主句的have不表示“拥有”而表示其他意思时，附加疑问要用do, 如：
You had a cold yesterday, didn’t you?
They don’t have coffee with breakfast, do they? 8.There be句型的反意疑问句，用there 作主语。 如：
There is something wrong, isn’t there?
There won’t be any trouble, will there? 不会有任何麻烦，是吗？
9.陈述部分的主语是everyone, someone, anyone, no one, nobody等不定代词时，其疑问部分的主语可用he, 也可用they. 如：
Everyone knows it, doesn’t he/don’t they?
英语反意疑问句的回答有点和汉语的相反。但一定要记住：只要回答是肯定的，都用yes，只要回答是否定的，都用no。这在主句是否定句的时候要特别注意。例如： Mr. Jones can’t speak French, can he? ？No, he can’t.

琼斯先生不会讲法语，对吗？？对，他不会讲法语。 Mr. Jones can’t speak French, can he? ？Yes, he can. 琼斯先生不会讲法语，对吗？？不，他会讲法语。 This is not a door, is it? －Yes, it is. It is an iron door. 这不是门，对吗？？不，这是门。是扇铁门。 十二、连接词
连接词是英语中的一个重要组成部分，它们连接英语的句子和段落，使文章流畅自然，使英语句子与句子之间，段落与段落之间的关系一目了然。中国的语法书上一般不专门涉及连接词。鉴于中国学生在应用英语（尤其是写作）的时候常常犯连接词错误，如不用连接词、在使用连接词时错用标点符号等，我们有必要专门讲述连接词。
英语中连接词分为两大类：连词性连接词（即连词）和副词性连接词。 连词
连词用来连接词与词、短语与短语或句子与句子。连词不能单独作句子成分，也没有词形变化。连词分为并列连词和从属连词两种。 （一）并列连词
并列连词用来连接句子中担任相同成分的词、短语或分句。常见的有七个单词和四个短语：and, but, or, for(因为), nor, so, yet; both…and…, not only….but also…., either…or…., neither…nor… 1．and用来连接词、短语或分句，表示并列或对称关系：
The man put on his coat and hat, and went out of the office. 那个人穿上外衣、戴上帽子，走出了办公室。
A car and a dictionary are both useful. 汽车和字典都有用处。 I went home and John stayed there. 我回家了，而约翰呆在那里。 2．but连接两个含义不同甚至相反的词、短语或分句，表示转折：
Not everybody is honest and hardworking, but Tom is. 并非每个人都诚实肯干，但汤姆是的。 We tried to persuade her to do it but failed. 我们尽力说服她去做，但没有成功。 3．or表示两者居其一，表示选择：
Which VCD player is better, this one or that one? 哪个VCD更好，这个还是那个？ Are you hungry or not? 你饿了没有？
4．For(因为)只能放在表示结过的分句后面，引导表示原因的分句： I must be going, for it’s getting dark. 我必须走了，因为天黑了。 He didn’t go there, for he was ill. 他没到那儿去，因为他病了。 5．Both…and…只能用来连接两个并列的词或短语，不能连接句子： His plan is both easy and practical. 他的计划既容易又实用。
Zhang Yimou is a famous director both at home and abroad. 张艺谋是一位在国内外都著名的导演。
Both this plane and its engines are made in China. 飞机和它的发动机都是中国制造的。 6．Not only…but also…不但能连接词和短语，而且还能连接分句。Also 有时省略。注意not only 位于句首时，主语和谓语需要倒装：

He is not only an actor but also a writer. 他不仅是演员，而且是作家。
He not only read it but also remembered what he had read. 他不但读过，而且记住了所读过的东西。
When we talk about the universe, we mean not only the earth, the sun, and the moon, but (also) all the other things too far away for us to see. 当我们谈到宇宙时，我们不但指地球、太阳和月亮，而且还指一切远得看不见的其他东西。
Not only did he say it but (also) he did it. 他不但说了，而且做了。（倒装）
Not only do the nurses want a pay rise, but also they want reduced hours. 护士们不但要求加工资，而且还要求缩短工时。（倒装）
7．Either…or…表示选择，“或者…或者…”、“不是….就是…”的意思。注意either…or…（整个结构作主语时）句子中的动词通常要和邻近的主语相一致。
Either you are wrong, or I am. 不是你错了，就是我错了。
Either you or he is going to get the job. 不是你就是他将获得这份工作。 Can I borrow either your car or your bike? 我可以借用你的汽车或者你的自行车吗？
If you’re late, you should make an apology to the host either immediately or later. 如果你迟到了，你应该立即或事后向主人道歉。
8．Neither…nor…表示“既不….又不…”的意思。注意neither…nor…整个结构作主语时，句子中的谓语动词通常要和邻近的主语一致：
Neither the students nor I am ready yet. 学生们和我都还没有准备好。 He worked neither for fame nor for money. 他干工作既不图名又不图利。
The girl could neither speak nor write the language. 这个女孩既不会说也不会写那种语言。 9．So(因此)，引导表示结过的分句，原因分句在前。（与for相反） It’s getting dark, so I must be going. 天黑了，因此我得走了。
I had a headache, so I went to bed early last night. 我头痛，于是昨晚很早就睡了。
10．Yet (然而)，有时和and 一起用，表示吃惊、表示转折，相当于but at the same time, however, nevertheless:
She is vain and foolish, and yet people like her. 她既虚荣又愚蠢，然而人们却喜欢她。
She’s a funny girl, yet you can’t help liking her. 她是个疯疯癫癫的女孩，然而你却禁不住喜欢她。 He worked hard, yet he failed. 他很努力，然而却失败了。 It’s strange, yet it’s true. 这事有点怪，却是真的。
He’s a wealthy, yet honest, businessman. 他是个富有而又诚实的商人。
It is only a little shop and yet it always has such lovely decorations. 那只是个小店，却总是有漂亮的装饰。
You can draw a good horse in five minutes, yet you kept me waiting for a year. 你能在五分钟内画出一匹好看的马，然而你让我等了一年。 （二）从属连词从属连词是用来引导从句的。
1．连词that, if, whether，连接代词what, which, who, whom, whose以及连接副词how, when, why, where可用来引导名词从句，充当主语、表语、宾语等。非正式文体中的宾语从句常省略that：
研友交流QQ群：385415060 考研英语直播课程报名关注@考神团队 新浪置顶微博
I think (that) he’ll be back in an hour. 我认为他一小时后就会回来。 Who they are doesn’t matter much. 他们是谁没什么大关系。 Can you tell me where he is? 你能告诉我他在哪儿吗？ He asked me if/whether I knew John. 他问我是否认识约翰。
此外，that, which, who, whom, whose, when, why, where等还可以引导定语从句。 2．连词when, while, before, after, till/until, since, as soon as等引导时间状语从句： She said hello to me when she saw me. 她看到我的时候，和我打了招呼。 I’ll wait here until you come back. 我将在这里等你回来。
3．连词if, unless引导条件状语从句；because, as, since引导原因状语从句： I’ll help her if she asks me to. 如果她要求我，我就帮助她。
I won’t help her unless she asks me to. 除非她要求我，否则我不会帮她。 He didn’t come because he was ill. 因为他病了，所以没来。
As he hasn’t appeared yet, we shall start without him. 既然他还没有出现，我们就先开始吧。 Since everybody is here, let’s begin. 既然大家都到了，咱们就开始吧。 4．连词in order than, so that引导目的状语从句；so…that…引导结果状语从句：
I locked the door in order that we might continue our discussions undisturbed. (=I locked the door in order to continue our discussions undisturbed.) 我把门锁上了，以便我们可以继续讨论而不受打扰。
The car ran so fast that I couldn’t see who was in it. 汽车跑得那么快，我没看清谁坐在里面。 5．连词than, as…as…, not as/so…as…用来引导比较状语从句： He is better educated than his brother. 他比他兄弟受的教育好。 He is as well educated as his brother. 他和他兄弟受的教育一样好。 He is not as/so well educated as his brother. 他没有他兄弟受的教育好。
6．连词although, though 引导让步状语从句；where, wherever 引导地点状语从句： I’ll go wherever you go. 不管你去哪儿，我就去那儿。 Stay where you are! 原地别动！
Though/Although she is rich, she’s not happy. 尽管她富有，但她并不幸福。
一般来说，连词性质的连接词连接两个分句或引导一个从句，两个分句或主从复合句之间用逗号连接。 （三）副词性连接词
副词性质的连接词不能象连词一样分句或主从复合句之间用逗号连接。也就是说它们不能连接两个分句或引导从句。它们引导的句子与前面的句子之间要用分号或句号，而它们与引导的句子之间往往用逗号。副词性质的连接词在写作中常常使用，主要分为以下几类：
1．表示顺序的，如first, in the first place, then, finally, in the end等等。尤其要注意then. 如： 误：He graduated from college in 2003, then he found a job. 正：He graduated from college in 2003, and then he found a job. He graduated from college in 2003. Then he found a job.
2．表示递进关系的，如in addition, what is more, furthermore, moreover等。注意in addition 与in addition to 的区别：in addition 是副词性质；而in addition to 是介词性质，后面必须接宾语。

3．表示转折关系的，如 however, nevertheless, nonetheless, on the contrary, in contrast, 等等。要注意不要把however 当成连词：
误：In 2003, the United States launched the war on Iraq on account of Iraq possessing weapons of mass destruction (WMD), however, no WMD has been found in Iraq so far.
正：In 2003, the United States launched the war on Iraq on account of Iraq possessing weapons of mass destruction (WMD). However, no WMD has been found in Iraq so far.
