【答案与解析】
1．A．本题考查虚拟语气。因为从句表示与过去事实相反的假设，故从句谓语动词用过去完成时，而主句谓语动词用would have +过去分词形式。
2．B．本题考查虚拟条件句中主句谓语动词的使用。因为从句用了过去完成时，可知主句谓语动词用would / could have +过去分词形式。根据句意，可知选B。
3．B. 根据答语，可知本题考查与过去事实相反的虚拟语气。故从句谓语动词用过去完成时，而主句谓语动词用would have +过去分词形式。
4．D．根据句意“在会上我没有看到你的姐姐。如果她来的话，她就见到我哥哥了”可知，这是考查对过去事实的虚拟。主句用could have done，故从句谓语动词应该用过去完成时。
【重点归纳】
一、虚拟条件句的类别
虚拟条件句可分为三类：一类是叙述与现在事实相反的情况；一类是叙述与过去事实相反的情况；另一类是叙述与将来事实相反的情况。其主句和从句的谓语动词构成如下：
1. 与现在事实相反
条件从句用过去时（be动词的过去式一律用were），主句用would （should/ might / cou ld）+动词原形”。如：
If I were you, I would accept the invitation to the party.
如果我是你的话，我将接受去舞会的邀请。
If I knew her well, I would tell you about her.
如果我很了解她的话，我将告诉你关于她的事情。
2. 与过去事实相反
条件从句用过去完成时，主句用“would /should/ might / could + have +过去分词”, 如：
If you had been there last night, nothing would have happened.
如果你昨天晚上在那儿的话，就没有什么事情发生了。
If I had got up earlier, I would have caught the first bus.
如果我起得更早一些的话，就赶上头班车了。
3．与将来事实相反
条件从句用过去时或者“were to + 动词原形”或者“should+ 动词原形”，主句用“woul d （should/ might / could）+动词原形”, 如：
If it were Saturday tomorrow, we wouldn’t have an exam.
如果明天是周六的话，我们就不考试了。
If you were to visit the school tomorrow, you would see Professor Smith.
如果你明天去参观学校的话，你就会看到史密斯教授。
If it should rain tomorrow, the sports meet would be put off until next Friday. 如果明天下雨的话，运动会将被推迟到下周五举行。
【特别提示】
在虚拟条件句中，谓语动词按照“后退一步法”使用，即：与现在事实相反，从句中用一般过去时；与过去事实相反，从句中用过去完成时；与将来事实相反，从句中用过去将来时。
二、虚拟条件句中的省略与倒装
如果if虚拟条件句中有were, had, 或者should等词时，可以省略if，把这些词放在主语前，形成倒装句。如：
If I should meet her (Should I meet her), I would tell her.
如果我遇见她的话，我就告诉她。
If I were in your position (Were I in your position), I would do it better.
如果我在你的位置上，我会做得更好。
If they had made preparations (Had they made preparations), they would have suc ceeded.
如果他们做了准备的话，他们就已经成功了。

3. I told your friend how to get to the hotel, but perhaps I _____ have driven her there. （2007陕西）

D. should
【答案与解析】
1．C。shouldn’t have done表示“本来不应该做某事而实际做了”。
2．C。根据句意，“本来这个湖应该是很漂亮的，但是现在被严重污染了”可知选C。shoul d 在这里表示“本来应该……，暗含着实际上不……”之意。
3．D。should have done表示“本应该做某事而实际上未做”，本句意为：“我告诉你朋友该怎么到达旅馆了，但是也许我应该开车把她送到那儿去”。
【重点归纳】
1. 错综时间条件句：
有时在非真实条件句中，主句谓语动词所表示的动作和条件从句中谓语动词所表示的动作并不同时发生，这时主句和从句的谓语动词要根据各自所指的不同时间选用适当的虚拟语气形式。如：
Had I taken my umbrella with me when I came out this morning, I should not be w et now.
如果我今天早上出来的时候带着伞的话，现在就不会淋湿了。（从句说的是过去的事情，而主句说的是现在的事情）
If you had followed the doctor’s advice, you would be all right now.
如果你（那时）听从我的建议的话，现在就不会有事了。（从句说的是过去的事情，而主句说的是现在的事情）
If I hadn’t finished my composition by now, I would be working on it tomorrow. 如果到现在为止我还没有完成作文的话，我明天还要接着写。（从句说的是现在的事情，而主句说的是将来的事情）
2．含蓄虚拟条件句：
有时一个假设的情况并不用条件从句表示，而用其它方式来表示，这样的句子叫含蓄条件句。
主要有以下几种情况。
1) 用with, without，but for等介词短语来替代条件从句, 它们都可以转换成由if引导的虚拟条件句。如：
We might have died without your help. =We might have di ed if you hadn’t helped us.
如果（那时）没有你们的帮助，我们可能已经死了。
Without the sun, nothing would grow. = If there was no the sun, nothing would g row.
没有太阳，万物都不能生长。
2) 用or, otherwise, but that, suppose/ supposing (that), provided / providing (that) 等引导的虚拟语气。如：
You didn’t come yesterday, or you would have seen him.
你昨天没有来，否则的话，你就已经看到他了。
I was very busy last week, otherwise I would have come to see you.
我上周很忙，否则的话，我就来看你了。
Supposing I was still a little child, I would study hard from now on.
假如我还是一个小孩子的话，我将从现在开始努力学习。
3) 通过上下文来表示虚拟：这种情况下，需要加以分析。
I would have given you more money, but I was so poor then.
我（那时如果有钱的话）就可以给你更多的钱了，但是我当时太穷了。
I would have called you, but I forgot your telephone number.
我本来可以给你打电话，但是我（那时）忘了你的电话号码。
Having known the fact in time, we couldn’t have said th at. = If we had known t he fact in time, we couldn’t have said that.
如果我们（那时）及时知道事实的话，就不会说那件事了。
Any man in his position would have done that.
处于他那个位置的任何人都会那样做的。
4）由should +动词原形或者should/could/might have +过去分词构成的虚拟语气。
种情况下，虚拟条件句经常省略，而只剩下主句结构，如：
I should have told you that, but I was afraid that you couldn’t accept the fac t.
我本应该告诉你那件事，但我担心你不能接受这个事实。
Tom, you are so lazy! This work should have been finished hours ago.
汤姆，你太懒了！这个工作本应该几个小时之前完成。
3. 在if it were/had been not for …句型中的虚拟语气
If it were not for…,表示对现在事实的假设；If it had not been for…,表示对过去事实的假设。
If it were not for the Internet, everything would be very difficult.
要不是互联网，一切都会变得很难。
Had it not been for your overcoat, I would have died.
要不是你那件大衣，我就被冻死了。

一．虚拟语气用于条件状语从句中 1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。 If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生：条件状语从句：①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况 (1). 混合/错综型虚拟语气 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，称为‘错综条件句’，动词的形式要根据它所表示的时间作出相应的调整。 If you had followed my advice, you would be better now.(从句说的是过去，主句是现在) If I were you, I would have taken his advice.(从句是现在，主句是过去) （2）省略if的虚拟语气
虚拟语气在非真实条件句中 ①错综时间条件句: 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，被称为错综时间条件句，动词的形式要根据它表示的时间作出相应的调整。如： If you had followed my advice just now, you would be better now. If you had studied hard before, you would be a college student now. ②if省略句 在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。否定句时not留在原来位置不变。如： If I were at school again, I would study harder. →Were I at school again, I would study harder. 如果我还有上学的机会，我会更加努力学习。 If you had come earlier, you would catch the bus. →Had you come earlier, you would catch the bus. 如果你来得早点，你就能赶上公共汽车。 If it should rain tomorrow, we would not go climbing. →Should it rain tomorrow, we would not go climbing. 如果明天下雨的话，我们就不能登山去了。 ③用介词代替条件状语从句 常用的介词有with, without, but for。如： What would you do with a million dollars? (=if you had a million dollars)
高考英语虚拟语气的用 法总结 -CAL-FENGHAI-(2020YEAR-YICAI)_JINGBIAN
高考英语虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 语气的种类： （1）陈述语气表示动作或状态是现实的，确定的或符合事实的，用于陈述句，疑问句和某些感叹句。如 We are ready. What a fine day it is! （2）祈使语气表示说话人的建议，请求，邀请，命令等。如 Open the door, Please. 应注意以下几点： 1.主语通常是第二人称you，但多不出现，动词用原形，否定用do not 或者don’t 加动词原形（或be） 如 Be careful next time. Don’t smoke here. 2.有时为了强调，主语也可以出现，而且可以是第三人称，谓语动词不加-s或者-es 如You be quiet. He stand up. 3.祈使语气可以用do加强语气如 Do come to see this Sunday. 4.在Let’s 的祈使句后，疑问部分通常用shall we；在Let us后，疑问部分用will you 如 Let’s go out for a walk after supper，shall we /Let us clean our classroom, will you 5. 6.祈使句与连词and连用时相当于一个条件句，而and之后则是表示结果。如Think hard and you will have a good idea. （3）虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如 If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如 If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中， If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如：
2013年同等学力英语语法专项复习：虚拟语气 一、总述 虚拟语气（subjunctive mood ）用来表示说话人的愿望、请求、意图、建议、怀疑、设想等未能或不可能成为事实的情况，以及在说话人看来实现可能性很小的情况。由于虚拟语气是动词的一种特殊表现形式，因而动词的变化形式体现出虚拟语气所包含的不同含义。虚拟语气用于非真实条件句时的构成如下表所述： 二、重要考点 1. 在非真实条件句中，有时从句的动词所表示的动作和主句的动词所表示的动作并不同时发生，这样的条件句中使用的虚拟式称为混合虚拟式。其构成视具体情况而定。例如： If I had taken my raincoat when I came out this morning, I would not be wet now. If I were you, I wouldn’t have missed the film last night. 2. 引导非真实条件从句的连词if 在正式文体中有时可以省去, were、had、should 等非行为动词这时应提到从句句首。 例如： If I were you, I wouldn’t feel sorry. →Were I you, I wouldn’t feel sorry. 3. 有些句子从表层结构上看是无if 引导的非真实条件句，但从深层意思上看if 是存在的。这种情况下主句动词仍需用虚拟式。这类句子中常出现without （如果没有），but for （要不是），otherwise （否则），but that （若不，后接一从句）等词或词组。例如： But for your help, they couldn’t have succeeded. She wasn’t feeling well. Otherwise，she wouldn’t have left the meeting so early. 4. 在It is + 形容词 + that 从句的句型中，that 引导的主语从句中的谓语动词采用should + 动词原形形式，其中should 常省略。可用于此句型的形容词还有：absurd, advisable, better, best, desirable, (un)fair, fortunate, good, imperative, important, incredible, just, natural, (un) necessary, odd, pleasant, possible, preferable, right, ridiculous, sad, silly, unusual, urgent, vital, wrong 等，表示必要、应该、建议、要求、惊讶、不相信等含义。例如： It’s necessary that we (should) set out at once. It’s proposed that a committee (should) be set up to look into the matter. 5. 具有“提议、建议、请求、命令”等含义的动词所带的从句（包括宾语从句和主语从句）中，谓语动词用should + 动 词原形形式。美国英语多用动词原形，英国英语多用should + 动词原形。有相同用法的动词还有：ask, advise, agree, arrange, beg, command, decide, demand, desire, determine, direct, instruct, insist, intend, maintain, move, order, persuade, pray, propose, recommend, request, require, stipulate, suggest, tell, urge。如： I suggest that we (should) go camping tomorrow. He insisted that our laboratory reports (should) be handed in

Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形 与过去事实相反had + 过去分词 should/ would/could /might + have+过去分词 与将来事实相反1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。
高考英语虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 语气的种类： （1）陈述语气表示动作或状态是现实的，确定的或符合事实的，用于陈述句，疑问句和某些感叹句。如We are ready. What a fine day it is! （2）祈使语气表示说话人的建议，请求，邀请，命令等。如Open the door, Please. 应注意以下几点： 1.主语通常是第二人称you，但多不出现，动词用原形，否定用do not 或者don’t 加动词原形（或be） 如Be careful next time. Don’t smoke here. 2.有时为了强调，主语也可以出现，而且可以是第三人称，谓语动词不加-s或者-es 如You be quiet. He stand up. 3.祈使语气可以用do加强语气如Do come to see this Sunday. 4.在Let’s 的祈使句后，疑问部分通常用shall we；在Let us后，疑问部分用will you 如Let’s go out for a walk after supper，shall we? /Let us clean our classroom, will you? 5.祈使句与连词and连用时相当于一个条件句，而and之后则是表示结果。如Think hard and you will have a good idea. （3）虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟 例如：If he were here, everything would be all right. If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如：

虚拟语气用法详解 一、条件句中的虚拟语气 1. 条件句中虚拟语气的形式 从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中 的虚拟语气根据不同的时间有三种不同的形式。 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如： If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分 利用他的时间了。 If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us. 要是他有空的话，它会帮助我们的。 If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 (3) 过去时的条件句中的虚拟语气。如： If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。 If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题 (1) 当从句的主语为第三人称单数时，谓语动词若是系动词be 时，可用was 代替were。但在倒装虚拟结构及if I were you, as it were 中，只能用were。如： Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。 (2) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。①从句的动作与过去事实相反，而主句的动 作与现在或现在正在发生的事实不符。如： If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会使工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。
虚拟语气(the subjunctive mood,又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。 一、动词的语气 语气用来区别讲话人对某一行为或事情的看法和态度。英语中的语气(mood有三种,分别是陈述语气、祈使语气和虚拟语气。 1.陈述语气 陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。 Where there is a will, there's a way. 有志者事竟成。 Can you help me carry the box upstairs 你能帮我把箱子搬到楼上吗? How I missed the life in the countryside! 我多么想念乡村的生活啊! 2.祈使语气 祈使语气表示说话人向对方提出请求或下达命令。 Come this way,please! 请这边走。 Don't make any noise, will you 别吵,行吗? Do be careful when crossing the street. 过马路时一定要小心。 3.虚拟语气 虚拟语气表示动作或状态不是客观存在的事实,而是说话人的主观愿望、假设或推测等。 If I were a bird, I could fly in the air. 如果我是一只小鸟,我就能在空中飞行。 I wish it were spring all the year round. 但愿四季如春。 May good luck be yours! 祝你好运! 二、条件句中的虚拟语气 英语中条件从句有两类,一类是真实条件句,另一类是非真实条件句。如果假设的情况可能发生,是真实条件句;如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。 A.真实条件句 真实条件句表示的假设是可能发生或实现的,主句和从句的谓语动词都要用陈述语气。 If he doesn't come at 8, we won't wait for him. 如果他八点不来,我们就不等他了。 If a flood happened in the past, there was usually a great loss of life and property.过去发生洪水的话,常有很大的生命和财产损失。 We shall go there unless it rains tomorrow. 如果明天不下雨,我们将去那里。 I'll let you use my bike on condition that you keep it clean. 如果你能保持车子干净,我就让你用我的自行车。 B.非真实条件句 在含有非真实条件句的复合句中,主句和从句的谓语动词都要用虚拟语气,其构成有三种形式: 与现在事实相反if条件句的谓语:were did
