虚拟语气的用法及经典练习题附答案
虚拟语气
概念
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。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
应用条件
在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，而不是根据客观实际，就用虚拟语气。
在非真实条件状语从句中的用法
真实条件状语从句与非真实条件状语从句
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。
例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴士。( 真实) If he is free, he will ask me to tell stories. 如果他是空闲的，他会要求我讲故事。（真实）If I were you, I would go at once.如果我是你，我马上就会去。（非真实，虚拟语气）If there were no air, people would die. 如果没有空气，人就会死亡。（非真实，虚拟语气）
用法及动词形式
例句：
1、表示与现在事实相反的情况：例： 1. If I were you, I would take an umbrella. 如果我是你，我会带把伞。（事实：我不可能是你） I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。（事实：不知道） there were no air or water, there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) I had any money with me, I could lend you some. 如果我带钱了，我就会借给你些。（事实：没带钱） he studied harder, he might pass the exam. 如果他再努力些，就能通过考试了。（事实：没有努力）
2、表示与过去事实相反的情况例：1. If I had gotten there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） he had taken my advice, he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话）
3、表示对将来情况的主观推测，与将来事实相反例： he should come here tomorrow, I should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。（事实：来的可能性很小） 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。（事实：不知能否下雪） she were to be there 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。
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。如：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，即将were, should, had等词置于句首，这种多用于书面语。如：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。
6、非真实条件句中的条件从句有时不表达出来，只暗含在副词、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，在多数情况下，条件会暗含在短语中，如without…., but for….等
如：But for his help, we would be working now. 要不是他的帮助，我们还会在工作呢。Without your instruction, I would not have made such great progress. 要是没有你的指导，我不会取得如此大的进步。We didn’t know his telephone number; otherwise we would have telephoned him. 我们不知道他的电话号码，否则我们就会给他打电话。
7、有时，虚拟条件句中，主、从句可以省略其中的一个，来表示说话人的一种强烈的感情。
①省略从句He would have finished it. 他本该完成了。You could have passed this exam. 你应该能通过这次考试了。
②省略主句If I were at home now. 要是我现在在家里该多好啊。If only
I had got it. 要是我得到它了该多好啊。、
虚拟语气的其他用法
用在wish 后的宾语从句
a、表示与现在事实相反的愿望，谓语动词用过去式
eg. I wish I had your brains. 我希望我有你那样的头脑。(事实：我根本比不上你)
b、表示与过去事实相反的愿望，谓语动词：had+done
eg: I wish I had known the truth of the matter. 我希望我原来知道这件事的真相。（事实：原来不知道）
c、表示将来难以实现的愿望，谓语动词：should/would + 动词原形
eg. I wish I should have a chance again. 我希望我还能有一次这样的机会。（事实：很难再有这样的机会了）
(注：if only和as if/as though也有相同用法）
用在目的状语从句中
1.在for fear that, in case, lest引导的从句中，若用虚拟语气时，从句谓语为：should + 动词原形。并且 should不能省略
examined the door again for fear that a thief should come in. 她又把门
检查了一遍，以防盗贼的进入。He started out earlier lest he should be late. 他很早就出发了以防迟到。
2、在so that, in order that所引导的目的状语从句中，从句中的谓语为：can / may / could / might / will / would / should + 动词原形。
goes closer to the speaker so that he can hear him clearer. 他走近说话的人以便能听得更清楚。He read the letter carefully in order that he should not miss a word. 他把信读得很仔细以便不漏掉一个单词。
其他用法
1、一想要(desire)二宁愿(prefer)三命令(order, command)四建议(advice. Suggest, propose)五要求(demand , require, request , desire , insist)中，无论主句谓语动词为何种时态，从句的谓语动词都用：“should + 动词原形”或只用“动词原形”。如：He suggested that we (should) take the teacher’s advice. He insisted that we (should) take the teacher’s advice. He demand that we (should) take the teacher’s advice. He ordered that we (should) take the teacher’s advice.
insist如果翻译成坚持某种动作才用虚拟语气；翻译成坚持某种观点就不用虚拟语气。
如：He insist he is a student. 他坚持说他是个学生。这个语句表示的是事实，因此在这个语句中不能使用虚拟语气。
suggest意为“建议”才用虚拟语气，意为“暗示”则不用虚拟语气。如：His face suggests that he looks worried . 他的表情暗含着他很担心。这个句子本身是事实，因此它就没有用到虚拟语气。
2、表情绪.观点的形容词或名词也要用虚拟语气.如:necessary、important、impossible、natural、strange、surprising、funny、right、wrong、better、a pity 等。
句型：It is.......that +主语从句，从句的谓语动词都要用should+原型或只用动词原型。
3、在even if, even though 所引导的让步状语从句中，可用虚拟语气，主句、从句的结构与if所引导的条件从句结构相同。如：Even if he were here himself, he should not know what to do. 即使他亲自来也不知该怎么办。（事实：他没来）Nobody could save him even though Hua Tuo should come here. 即使华佗在世也救不了他。（事实：华佗不在世）
4、在whatever，whichever，whenever，whoever, wherever，however, no matter wh-word 等引导的让步状语从句中，从句虚拟语气结构为：指现在或将来：may +动词原形。如：We will finish it on time no matter what may happen. 不管发生什么事，我们都要按时完成。We will find him wherever he may be. 无论他在哪里，我们都要找到他。I will wait for him no matter how late he may come. 不管他来的多么晚，我都会等他。指过去：may +完成式。如：You mustn’t be proud whatever great progress you may have made. 不管你取得了多么大的进步，你也不能骄傲。We must respect him no matter what mistakes he may have made. 不管他犯过什么错误，我们必须尊敬他。
5、一般would rather, had rather, would sooner等之后的宾语从句常表示与客观
事实不相符的一种愿望，故使用虚拟语气。其虚拟语气的结构为：
过去: had + 过去分词 ; 现在: 过去时(be用were ) ; 将来: 过去时(be用were )如：I’d rather you had seen the film yesterday. 我倒想你昨天看过了这场电影。I’d rather you were here now. 我倒想你现在在这儿。We’
d rather you went her
e tomorrow. 我们倒想你明天去那儿
6、虚拟语气还可用在定语从句中，表示：“早该做某事了”时，定语从句中的谓语动词须用虚拟语气，其虚拟语气的结构为：It is (high / about) time that + 主语+ 动词的过去式/ should + 动词原形，即从句用虚拟过去式。如It is time that I went to pick up my daughter at school. 我该去学校接我的女儿了。
It is high time you should go to work. 你早该上班了。
7、简单句中的虚拟语气
（1）说话时，为了表示客气、谦虚、委婉而有礼貌，言语常使用虚拟语气。其虚拟
语气的结构形式常为：would / could / might / should + 动词原形。如：Would you mind my shutting the door? 我把门关起来你介意吗？You should always learn this lesson by heart. 你要把这个教训牢记于心。I should agree with you. 我应该同意你的观点。
（2）表示“祝愿”时，常用may + 主语+ 动词原形。如：May you have a good journey! 祝你一路顺风。May your youth last for ever! 祝你青
春永驻。
（3）表示强烈的“愿望”、“祝愿”时，常用动词原形。如：Long live the Communist Party of China. 中国共产党万岁。God bless us. 上帝保佑。（4）习惯表达中常用的虚拟语气。
①提出请求或邀请。如：Would you like to have a talk with us this evening? 今天晚上来跟我们聊天好吗？Could I use your bike now? 我
可以用一下你的单车吗？②陈述自己的观点或看法。如：I should glad to meet you. 见到你我会很高兴。I would try my best to help you. 我
会尽力帮助你。③提出劝告或建议。如：You’d better ask your father first. 你最好先问一问你的父亲。You should make a full investigation of it first. 你应该先全面调查一番。④提出问题。如：Do you think he could get here on time? 你认为他能按时来吗？Do you expect he would tell us the truth? 你期望他会告诉我们真相吗？⑤表示对过去情况的责备时，常用虚拟语气。其虚拟语气的结构为：情态动词 + have + 过去分词。如：You should have got here earlier. 你应该早就到这里了。You should have returned it to him. 你应该把它还给他了。
省略的虚拟条件句型
省略连词if
有时可将条件从句的连词if省略，但此时应用倒装句型，即将从句中的were, should, had 等提到句首：Were I Tom, I would refuse. 如果我是汤姆，我会
拒绝。I will go, should it be necessary. 假若有必要，我会去的。Had it not been for the bad weather we would have arrived in time. 若不是天气坏，我们就准时到达了。
【注】①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。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…)
省略条件句的主语和其后的动词be
若主从句主语一致，且谓语部分包含有动词be，通常可将主语和动词be省略：If repaired earlier, the tractor would not have broken down. 要是早点儿修一下，拖拉机就不会抛锚了。(=If it had been repaired earlier…)
省略“it+be”
If necessary, I would send more farm-hands to help you. 如果需要的话我会派更多的民工去帮你。(=If it was necessary, I would…)
省略整个条件从句
这样的省略通常需要借助一定的上下文，即省略条件从句后，所剩下的主句的意思在一定的上下文中意思是清楚的：I might see her personally. It would be better. 我可以亲自去看她，这样好一些。(=…If I saw her personally, it would be better.)
在含蓄条件句中的用法
(1) 条件暗含在短语中。如：We didn’t know his telephone number; otherwise we would have telephoned him. 我们不知道他的电话号码，否则我们就会给他（暗含条件是otherwise）Without your help, we wouldn’t have achieved 打电话。
so much. 没有你的帮助，我们不可能取得这么大的成绩。（暗含条件是介词短语without your help）But for your help, I would not have succeeded in the experiment. 如果没有你的帮助，我的实验就不会成功。（暗含条件是but for your help）It would cause great trouble not to lubricate the bearing immediately. 不立即润滑轴承就会引起很大的故障。（暗含条件是not to lubricate the bearing immediately）(2) 条件暗含在上下文中。如：I would not have done it that way. 我是不会那么做的。（可能暗含if I were you）I was busy that day. Otherwise I would have come to help you. 我那天很忙。否则我会来帮你的。（可能暗含if I hadn’t been so busy.）You might come to join us in the discussion. 你可以参加我们的讨论。（可能暗含if you wanted to）I would have bought the DVD player. 我是会买下那台影碟机的。（可能暗含if I had the money）But for the storm, we should have arrived earlier. 要不是碰到暴雨，我们还会早些到。（可能暗含if it had not been for the storm）。

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）
虚拟语气用法详解
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 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 Univer sity, he would make full use of his time. If he were to come here, he would tell us about it. (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us.
If he studied at this school, he wo uld know you well. (3) 过去时的条件句中的虚拟语气。如：If I had seen the film, I would have tol d you about it. If I had got there earlier, I would have met Mr. Li. 3.运用条件句中的虚拟语气时，须注意的几个问题 (1) 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。 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. If they had informed us, we would not come here now. (2) 当虚拟条件句的谓语动词含有wer e, should, had时，if可省略，而将were, s hould, had等词置于句首。如： Should he agree to go there, we wo uld send him there. Were she here, she would agree wit h us. Had he learnt about computers, we would have hired him to work here. (3) 有时，句子没有直接给出假设情况的条件，而须通过上下文或其他方式来判断。如：
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.

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。
高考英语虚拟语气语法专项讲解
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) 以下表格是虚拟语气用于条件状语从句中时，主句和从句谓语动词的形式： 条件状语从句主句与过去事实相反had + 过去分词should /would/could/might + have + 过去分词与现在事实相反一般过去时(be用were) would/should/could/might + 动词原形 与将来事实相反一般过去时或should(were to) + 动词原形 Would/should/cold/might + 动词原形 有时候在使用时可省略if,句子则可换成下列形式，即“were / had / should +主语”。如：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。
虚拟语气用法总结讲课稿
虚拟语气用法总结
虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达： a. 非真实的情景，不可能发生的事，即某种与事实相反或难以实现的情况，或说话人主观愿望。 b. 与客观事实相反地情景，即强制性虚拟语气，表示建议、命令、劝告这一类的意思上，表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的，其特点是主从句时态的不一致，而且一般有明显得标志。 二.虚拟语气的考点为： 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反：从句用一般过去时，主句的谓语用would (could, might) ＋动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反：从句用过去完成时，主句的谓语用would (could, might) ＋现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反：从句用should (were to，did) + 动词原形，主句的谓语用would (could, might) ＋动词原形 If it should/were to snow tomorrow, I would go skiing.
注意：虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略，再把were, should或had 移到从句句首，实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词，通常将if省略，主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中，省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间，这时主，从句谓语动词的虚拟语气形式因时间不同而不同，这叫做混合条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…，要是…多好”的语气表示与事实相反的情况，或表示将来不太可能实现的愿望。其宾语从句的动词形式为： He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形，其中should 经常被省略。这类动词包括： suggest, propose, recommend, demand, order, command, desire, require, insist,
