B6 U1学案 3 (虚拟语气)
高二英语虚拟语气学案2013.2.20 概述：虚拟句用来表示说话人的主观愿望、假设、提议或推测。确切地说，虚拟句专门用来表达说话人根据主观愿望或看法，幻想要实现根本不可能或很难实现的事情。
用虚拟句的目的：
1.表示与客观事实相反的假设
我要是你，我就去向他道歉。
If I ________ you, I would apologize to him.
2.表示一种强烈而又不能实现的主观愿望。
我多么希望有一架属于自己的飞机呀！
How I wish that I had a plane of my own!
要是从一开始我们就没有卷入其中就好啦！
____ _____ we hadn’t involved in it at the very beginning!
3.表示主观推测
要是波利激动起来，他可能会马上走开。
If Polly got excited, he would leave immediately.
4.表示提议、建议或语气不肯定
My suggestion is that the thief should be sent to the police.
5.表示语法规定的需要
It is important that the work should be done today.
6.表示良好的祝愿
Long live our friendship! God bless you!
虚拟句的主要用法：
1.虚拟句多用if引出条件从句
（1）与现在事实相反，表条件的从句一般用动词过去式，表示结果的主句一般用should/would do/be。（也可以用情态动词could, might表达出情态意义）
If he ______(be) here, I ________ (ask) him for advice.
If I ________ (no have) such a headache, why ______ I ______ (take) the medicine?
（2）与过去事实相反，虚拟条件句表达与过去客观事实相反或主观意愿，从句一般用had done，主句用should/ would have done。（也可以用情态动词could, might表达出情态意义）
If you ____________(go) to meet me at the station yesterday, I _________________ (not lose) my way.
If it ____________(not be) for your constant help, he __________________ (fail) in the experiment.
（3）与将来事实可能相反的推测条件句。对于未来的事情，很难肯定说是与事实相反，只能表明说话人主观上认为或判断某件事发生的可能性不大。表示条件的从句一般用should do，表示结果的主句采用should/ would do。（也可以用情态动词could, might 表达出情态意义）（条件句中谓语还可以用were to + do，但用法比较次要。）
If there ___________(be) a flood, what ________ the villagers _______(do)?
If he ____________(come), I ___________(ask) him to wait here.
If I were to tell you all I know, you would be angry.
表示与将来事实可能相反的推测条件句，主句的结果可以是说话人对未来发生事情所做的一种有准备的打算、劝告和鼓励，并非是根据从句推测出来的，所以其主句还可以用陈述语气和祈使语气。
If there should be any difficulty, try to conquer it yourself.
If you should meet with any difficulty, I shall help you.
（4）引导词if的省略
在if引导的虚拟条件句中，如果从句谓语中含有were, should,和had这样的系动词和助动词，可以省略if，但是必须用倒装句。如果从句用否定词，否定词必须放在主语的后面。
If he were in your place, he would also do the same thing.
→_______ he in your place, he would also do the same thing.
If you should change your mind, give me a phone call.
→__________________________________________.
If it had not been for him, we __________________ (lose) the chance.
→_______________________________________________________.
2.含蓄条件句和含蓄结果句
虚拟条件句经常是不完整的。有时只有结果的主句而省略了条件从句或将条件从句暗含在上下文或各类词、短语中，这类条件句叫含蓄条件句。有时只有条件的从句而省略了主句，这叫做含蓄结果句。
I would never have done such a thing. (省略if I were you)
Without guidance they would not be able to go through the forest.
(在without guidance短语中含有if they were not guided)
You might have taken all the things away. (条件句暗含在上下文中)
If Lei Feng were alive!
If only the snow had stopped! （雪要是停了多好啊！）
If I had only known! （我早知道就好了！）
3.其他主从复合句所包含的虚拟句
（1）通过主语从句表达的虚拟句
在用it作形式主语的主语从句中，即it is +形容词+ that…句型里，从句的谓语形式经常使用虚拟语气，动词形式常用should do。
It is necessary that all should be present at the meeting in time.
It is requested that we should be ready to start out at any time.
（2）在it is (high) time…中
在该句型中，由于句子意义主要表示说话人提议的主观看法，通常要用虚拟句来完成。
动词形式一般用过去式did或should。
It is high time all of us did some real things.
It is time you should take place of me.
（3）通过宾语从句表达的虚拟句
在这样的虚拟句中，主句谓语动词通常表示说话人的主观要求、愿望、建议、命令和
遗憾等。主句谓语动词常有command(命令), order, suggest, recommend(推荐), demand, propose(建议), request, require, insist, wish, desire(要求)等。从句使用should +do, should 可以省略。（口语中这些动词也可以使用陈述语气。）
They demanded that the machine _____________(repair) right now.
* would rather后的宾语从句用一般过去式表示现在或将来要做的事；用过去完成时表示过去做的事。
I’d rather we ________ (have) a rest now.
I’d rather you _____________(tell) him the news that day.
（4）通过表语从句表达的虚拟句
主句的主语如果是表示抽象概念的名词（如wish, suggestion, aim, order, requirement, desire, decision, arrangement等），从句中的谓语动词就要用虚拟语气，用(should) +动词原形。
His strongest wish is that his son should continue what he has been doing all his life.
The decision is that you should be given disciplinary punishment.(纪律处分)
如果主语是抽象概念的名词，但意义并非反映说话人的主观看法，而是一个客观事实，从句应该用陈述语气。
The question is that we haven’t enough hands up till now.
The trouble is that we can not get in touch with them.
* 主句中的谓语动词如果是be，look, seem等，后面引出表语从句的连接词可以使用as if或as though, 动词形式可以用did或had done.
I feel as if I __________(be) here for a hundred years.
It seems to me as if you had been lying all the time.
（5）通过同位语从句表达的虚拟句
在抽象名词如order, wish ,suggestion, decision, advice等词的后面跟同位语从句时，从句的谓语动词要用虚拟语气，与上面的表语从句用法相似。
The doctor has given his advice that the patient __________ (have) a bath every day.
（6）as if 或as though引出的状语从句通常使用虚拟句。但如果说话人将as if或as though 引出的从句内容看作是事实，则谓语动词也可以用陈述语气。
* 看下面的句子，总结谓语动词的用法：
The old couple loved Roland as if he were their own son.
He talks as though he had joined in the battle.
He behaved well as if he had had plenty of determination.
Jerry speaks as though he were a VIP.
(如果从句的谓语动作与主句所表示的时间相同，从句就用动词___________形式)
(如果从句的谓语动作发生在主句之前，从句就用动词___________形式)
4.虚拟条件句可以被某些句子成分代替
用介词短语代替:But for your warm-heartedness, he wouldn’t be alive today.
Without her mother to raise her, she could not have sat up.
用分词短语代替: Given an opportunity, he might have become a hopeful poet.
Time permitting, I would go to see some classmates.

高考虚拟语气用法详解()
高考虚拟语气用法详解 一·语气概述 和时态语态一样，语气也是谓语动词的一种形式，它表明说话者的目的和意图。英语中有三种语气：陈述语气，祈使语气和虚拟语气。（有的语法书说语气有四种，即还包括疑问语气）。 eg：①He doesn’t see very well in his right eye .他右眼视力不太好。（陈述语气） ②Have they ever been to Australia ?他们去过澳大利亚没有？（疑问语气） ③Please read through the instruction in advance .请先通读说明书。（祈使语 气） 二·虚拟语气概述 在英语中，由于说话人的意图不同，动词需用不同的形式，称为语气。虚拟语气是指说话人表示一种假设的情况，一种愿望，怀疑，推测，请求等，即认为动词所表示的动作或状态并非事实。虚拟语气可用于状语从句，名词性从句，定语从句及其他结构中。 三·非真实条件句中的虚拟语气 真实条件句（遵循主将从现原则） A.由If引导的两种条件句： 非真实条件句（虚拟语气） 以下为If在非真实条件句中虚拟语气的形式和用法： 假设类型If从句主句 与现在事实相反did (be用were)should/would/ could/might do 与过去事实相反had done should/would/ could/might have done 与将来事实相反1)did 2)were to do 3)should do should/would/ could/might do eg：①If I were you ,I would reconsider their advice .如果我是你的话，我会重新考虑他们的意见。（与现在事实相反） ②You would not have caught a cold if you had put on more clothes .如果你多穿了些衣服，你就不会得感冒了。（与过去事实相反）

高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。 （2）语气的种类 A. 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。 We are not ready. Did it rain all day yesterday? What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使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。 2. 虚拟语气 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟语气。 1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。 如： If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。 （事实是：天在下雨，我们不能出去野餐。表示愿望。） If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。 （事实是：他没来这，他不可能帮助你。表示对他的良好印象。） 2. 与过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited.
虚拟语气导学案及答案
M6 U3 Grammar Unreal conditionals 虚拟语气 【知识准备】英语中的语气分为陈述语气、祈使语气、虚拟语气三类。虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。 条件状语从句分类 条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设或实际可能性不大的情况，故采用虚拟语气。 eg： 1. If he doesn't hurry up,he will miss the bus. 2.If he is free,he will ask me to tell stories. 3.If I were you,I would go at once. 4.If there were no air,people would die. 以上四句中和是真实语气；和是虚拟语气 【自主探究】一、状语从句中的虚拟语气 (一) if 引导的条件状语从句 1 If I had time, I would attend the meeting. 2.

If he had come earlier, he wouldn’t have missed the first bus. 5 If the headmaster came tomorrow, we would have the meeting. 6 If it were to rain tomorrow, the sports meeting would be put off. 7 If he should make a mistake, you should not blame him. 与现在事实相反与过去事实相反 与将来事实相反 感悟：与现在事实相反 1.

If I had earned a lot of money last year, I would have bought a car. 2. If the earthquake hadn’t happened in Wen chuan in 2008, many people wouldn’t have lost
英语虚拟语气语法归纳总结
虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it. If you had taken your teacher’s advice, you wouldn’t have made such a mistake. If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping. 附注： 虚拟语气，条件状从倒装 状语从句中，去掉if,提前were/ had/ should 如：If I were you, I would give up. →Were I you, I would give up If you had taken the advice, you would have…. →Had you taken the advice, you would have… If the world shou ld come to an end,…… →Should the world come to an end…… 另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）
虚拟语气用法总结及详细解析
虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告，建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。此外，如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird，I would be able to fly in the air. 如果我是一只小鸟，我就能在空中飞行。 I wish I could pass the examination. 我希望我能通过考试。
If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事的始末。 4、有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 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。 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，我现在也会成为一个工程师了 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。 ②从句的动作与现在事实相反，而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即把were, should, had等词置于句首，这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话，我们就派他去。 Were she here, she would agree with us.如果她在这儿的话，她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话，我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had 等缩略成Weren't，Shouldn't，Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏，我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time，I would come. 假若我有时间，我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来，暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中，如without…, but for…,otherwise（要不是因为）等 But for his help, we would be working now. (要不是他的帮助，我们还会在工作呢。

高中英语 第二册 语法总结 虚拟语气
新概念英语第二册语法总结：虚拟语气 虚拟语气分三种情况来掌握： 1、虚拟条件句。 2、名词性虚拟语气。 3、虚拟语气的其他用语。 一、虚拟条件句： 条件状语从句是非真实情况，在这种情况下要用虚拟语气。 1、条件从句与现在事实不一致，其句型为： If 主语＋过去时，主语＋should(could, would, 或might)＋动词原形，如： If I were you, I would study hard. If it rained, I would not be here now. 2、条件从句与过去事实不一致，句型为： If 主语＋had＋过去分词，主语＋should(could, would, 或might)＋have＋过去分词，如：If the doctor had come last night, the boy would have saved. If I had not studied hard, I would have failed in the exam last term. 3、条件从句与将来事实不一致，句型为： If 主语+should(were to, 过去时)＋do，主语＋should(could...)＋原形do，如： If it should rain tomorrow, we would stay at home. If I were to go to the moon one day, I could see it with my own eyes. If you missed the film to night, you would feel sorry. 注意问题： 1、If条件句中绝对不可出现"would"。 2、根据句中的时间状语，有时可能出现“混合虚拟”的情况，即主句可能是现在的情况，条件句也许是发生在过去的情况，但都是遵守上述句型。 3、在条件句中如果出现were, had, should可省去if，将主语与这些词倒装，例如： Had the doctor come last night, the boy would have saved. Were I to go to the moon one day, I would see it with my own eyes. Should it rain tomorrow, we would stay at home.

第一部分：语气的定义和种类 1 语气(mood) 语气是动词的一种形式，表示说话人对某一行为或事情的看法和态度。2 语气的种类 ⑴、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： ①There are two sides to every question.每个问题都有两个方面。 ②Were you busy all day yesterday?昨天一整天你都很忙吗？ ③How good a teacher she is!她是多好的一位老师啊！ ⑵、祈使语气：表示说话人对对方的请求或命令。如： ①Never be late again!再也不要迟到了。 ②Don’t forget to turn off the light.别忘了关灯。 ⑶、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： ①If 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。 ②I wish I could pass the examination.我希望我能通过考试。 ③May you succeed!祝您成功！ 虚拟语气在语法里算得上是个难点。让我们就从最简单的开始吧。 第二部分：简单句中的虚拟语气 一、情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌、或委婉的语气，常用于日常会话中。 如： ⑴.Would you be kind enough to show me the way to the post office?请你告诉我去邮局的路好吗？ ⑵.It would be better for you not to stay up too late.你最好别熬夜到很晚。 二、表祝愿。 1、常用“may+动词原形”表示祝愿，但愿，此时may须置于句首（多用于正式文体中）。 ⑴、May good luck be yours!祝你好运！ ⑵、May you be happy!祝你快乐！ ⑶、May you do even better!祝你取得更大成就！ ⑷、May you have a good time. 祝愿你玩的痛快。
虚拟语气的特殊用法学案
虚拟语气的特殊用法 一、混合式虚拟语气 条件从句中的动词所表示的动作和主句动词所表示的动作发生的时间不一致时，动词的形式决定于要表示的具体时间。 使用混合式虚拟语气时,注意要抓住主从句中时间的象征性词汇（如now, yesterday 等）来确定是与哪种事实相反，然后再根据主从句中谓语动词的构成来确定。 If you had spoken to him yesterday, you would know what to do now. 如果你昨天对他讲的话，你现在就知道怎么做了。 If the boy hadn't been saved this afternoon, his family would not be in peace now. 如果那个男孩今天下午没有被救，他的家现在就不会如此安宁。 You would be much better now if you had taken my advice. 假如你接受了我的意见，你现在就会好得多。 二、含蓄条件句 含蓄虚拟条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。常用来表示含蓄虚拟条件的手段有： 1.介词或介词短语，如but for(要不是……), without, in case of, under more favourable conditions（在更有利的条件下）等取代了if引导的条件状语从句。 Without air, there would be no life on the earth. 要是没有空气，地球上就不会有生命了。 He would have failed but for.his teacher's timely advice =if it had not been for his teacher's timely advice 如果没有老师及时的建议的话，他可能失败了。 We could have done the work better in that case. 要是那样的话，我们本可以把工作干得更好一些的。 We could have done better under more favourable conditions. 在更有利的条件下，我们还可以做得更好些。 2. 用but that+从句（要不是，若非），otherwise, or, but 等分句来代替if引导的条件状语从句。 But that he saw i t with his own eyes, he couldn’t have believed it. 要不是亲眼所见，她不可能相信这事的。（从句用陈述语气，主句用虚拟语气） He would have come to see you yesterday morning but he had an important meeting to attend.他昨天上午就会来看你了，可他有个重要的会议要参加。（主句用虚拟语气，分句用陈述语气） I was ill that day. Otherwise/ or I would have taken part in your birthday party. （本句省略的条件句为If I hadn’t been ill that day.）（如果那天我没生病的话）我那天生病了，否则我就参加你的生日聚会了。 1. If you _____________(follow) my advice yesterday, you _____________(be) better now.
可用虚拟语气的用法总结
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。 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 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： Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三．含蓄条件句

高考虚拟语气专项讲解
虚拟语气 一、考点聚焦 1、虚拟语气用于条件状语从句中 （1）表示与现在事实相反的假设，条件状语从句中的谓语动词用“过去式（be动词的过去式用were）”，而主句中的谓语动词用“would / should/ could / might + 动词原形”。如：If I were a boy, I would join the army. If the had time, she should go with you. （2）表示与过去的事实相反，条件状语从句中的谓语动词用过去完成时，主句中的谓语动词则用“would / should / might / could + have +过去分词”。如： If he had taken my advice, he would have succeeded in the competition. （3）表示与将来事实相反，条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形，而主句中的谓语动词则用would / should/ could might + 动词原形。如； If it were to rain tomorrow, the football match would be put off. （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作相应调整。如： If they had worked hard, they would be very tired.(从句说的是过去，主句指的是现在) Were I a boy, I would join the army. Had he taken my advice, he would have succeeded. Were it not for the expense, I would go to Britain. 2、虚拟语气用于名词性从句 （1）虚拟语气在宾语从句中的运用。 ①“wish + 宾语从句”表示不能实现的愿望，译为“要是……就好了”等。表示现在不能实现的愿望，从句中的谓语动词用一般过去时；表示将来不能实现的愿望，从句中的谓语动词用“would/could + 动词原形”；表示过去不能实现的愿望，从句中的谓语动词用“had + 过去分词”或“could(should) + have + 过去分词”。如： I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. ②在表示建议、要求、命令等的动词suggest、advise、propose、demand、require、insist request、command、order等后的宾语从句中，谓语动词用should + 动词原形或是动词原形。如： She suggested we (should)leave here at once. The doctor ordered she should be operated. （2）虚拟语气在同位语从句和表语从句中的运用。
