虚拟语气用法归纳
英语的动词一般可带有三种不同的语气：陈述语气，祈使语气和虚拟语气。不同的语气用动词的不同形式（或句法形式）来表示。
一、虚拟条件句
条件句有两类：一类是真实条件句，一类是虚拟条件句
如果假设的情况是有可能发生的，就是真实条件句，谓语用陈述语气。
If you don’t work hard, you will fail.如果你不努力，就会失败。
If it is fine tomorrow, we will go for a picnic.如果明天天气好，我们就去野餐。
如果假设的情况过去、现在、将来都不存在，或者可能性极小，则为虚拟语气
虚拟条件句和对应主句的动词形式列表：
1.与现在事实相反的虚拟
What would you do if you won the lottery?假如你中了彩票，你会做什么？
If I were you, I would seize the chance to go abroad. 如果我是你，我会抓住这次出国的机会。
If I had a lot of money now, I would travel around the world.假如我现在有很多钱，我会环游世界，
2.与过去事实相反的虚拟
If you had been here yesterday, you would have seen her.如果昨天你在这里，就会见到她了。If he had driven more carefully, he would not have had the car accident yesterday.如果他小心驾驶的话，昨天就不会出事故了。
3. 与将来事实相反的虚拟
If it were to rain/should rain/rained tomorrow, our plan would be put off.假如明天下雨，我们的计划才可能推迟。（下雨的可能性很小）
If we were to picnic, we would not be able to help.如果到时候我们去野餐，就没办法帮忙了。（不会去野餐）
二、错综、混合虚拟语气
通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。
1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设)
2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设，主句是对现在的假设)
3. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设，
主句是对现在的假设)
4. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设，主句是对将来的假设)
5. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设，主句是对现在的假设)
6. If I were your mother, I would let you go out this weekend. (从句是对现在的假设，主句是对将来的假设)
三、含蓄虚拟语气
虚拟语气中的“含蓄之美”指的是含蓄虚拟语气。因为有时假设的情况并不是以if引导的条件从句形式出现，而是通过一些短语等形式暗示虚拟语气的存在，常用的词语有with, without, but for, otherwise, or，even, in case of, what if(如果…将如何)等等，这种句子往往有主句而无从句(考试时多数情况是对过去的假设)。
But for your encouragement, I would not have been admitted to this university. 没有你的鼓励，我不可能考上这所大学。（过去）
Without water, all lives would die. 没有了水，所有生物都会死。（现在）
He felt too tired yesterday, or he would have attended my party. 他昨天太累，否则就能来参加我的派对了。（过去）
I was having a meeting, otherwise I would have come to see you off. 我当时在开会，否则一定会去送你。（过去）
四、虚名词性从句的虚拟语气
含有should +V的用法，这一部分主要是有关建议和命令的相关从句，包括主语从句，宾语从句，表语从句，同位语从句以及与之相关的形式主语宾语之类的从句。记忆口诀：一个坚持(insist)，两个命令(order, command)，三个建议(suggest, advise, recommend)，四个要求(ask, require, demand, request)。
1. 宾语从句的虚拟语气
He insisted that the meeting be put off.
The general ordered (that) all the soldiers (should ) leave.
He gives orders that the soldiers (should) leave.
2. 表语从句的虚拟语气
My suggestion is that we (should) stay here for a rest.
3. 同位语从句的虚拟语气
There is no suggestion that she (should) resign.
4. 主语从句的虚拟语气主要体现在It做形式主语的三种情况：It’s +p.p +that ；It’s + adj. +that；It’s + n. +that
常用的动词recommand, demand, desire, order, request, require, suggest,command
常用的形容词important, necessary, right, advisable, natural, strange, surprising, regretful,urgent, vital, insistent, essential
常用的名词duty, pity, no surpise, no wonder, shame, regret
其实这些词在句子中其实也有建议命令类似的的意思
It’s important that you should take the medicine.
It’s a pity that you should refuse the invitation.
It’s essential that we should learn some knowledge about fist aid.
It’s demanded that all the students should go to the playground.
It was suggested that he should join the club activities.
5. It为形式宾语的情况实际上是上面形式主语的一种变形，是以it为形式宾语的复合宾语从句，it后面的宾语补足语多为形容词或名词，常见词就是上面形式主语后面的那些词。
I consider it vital that he (should) think deeply before acting.
We think it necessary that the meeting (should) be put off.
6. 某些词语如suggest, insist 等有双重含义，所以在使用的时候要注意什么时候用虚拟语气，什么时候不用虚拟语气。
Her smile suggested that she was in favor of the plan.(suggest表示“表明、暗示”时不用虚拟语气)
We insisted that what the boy did was wrong.（insist表示对过去发生的事实的坚持时不用虚拟语气）
五．虚拟语气在特殊句式中的运用，主要有两种情况：
I. would rather, It’s time…, for fear that…
would rather在使用时要注意它的不同用法。因为本身would rather可以直接接动词原形，构成would rather do sth. (than do sth.else); 或者would do sth. rather than do sth.else.而虚拟语气的would rather 是这样使用的would rather sb. did(对现在或将来的假设)/ had done(对过去的假设)
I would rather he didn’t go now.
They would rather they hadn’t attended the party.
It’s (about) (high) time (that)…从句中常用过去式(有时也用should do), 含建议的意思。汉语的意思为“是该做…的时候了”，也等于It’s time for sb. to do sth.
It’s high time (that) we went home.
It’s high time that we (should) go home.
It’s high time for us to go home.
for fear that 后面可以接虚拟语气should do，也可以接其他语气，但依然会有一个情态动词。
I will not make a noise for fear that I should / might disturd you.
II. wish+clause; as if/ though+ clause; If only这三种情况的虚拟语气有点相似。
wish后的宾语从句，谓语动词要用虚拟语气，其形式主要有三种wish sb. did(对现在的虚拟); wish sb. had done(对过去的虚拟); wish sb. would do (对将来的虚拟).偶尔在对过去的虚拟时，也会出现wish sb. would have done的情况。
I wish I knew what was going to happen.
She wished she had stayed at home.
I wish I would have seen her last night.
★此时要注意表示语气很强时用How sb. Wish+ clause, 其用法同上。如果要用was依然换成were.
How I wish I were a bird.
as if/ though出现的虚拟语气主要有两种情况：主句+as if/ though引导的状语从句；seem/ look/ smell +as if/ though引导的表语从句。
主句+as if/ though引导的状语从句：主句+as if/ though+主语+did/ were(对现在的假设)；主句+as if/ though+主语+could/ would do(对将来的假设)；主句+as if/ though+主语+had done(对过去的假设)
seem/ look/ smell等的从句情况基本上和上面一致。
She talks as if she knew everything.她说话的样子就好像她什么都知道一样（现在）
He behaved as if nothing had happened.他表现得像什么事也没发生一样（过去）注意不需要用虚拟语气的情况
If only引起的感叹句要求用虚拟语气，表示愿望。形式为：用过去式或者would/ could do, 表示与现在或未来事实相反的愿望；用过去完成式表示与过去事实相反的愿望。
If only he were here!他在这里就好了
If only you would listen to our advise! 你要是听了我的建议就好了
If only I had not been busy last week! 上周我要是没有一直忙就好了
★If only 也可以用于虚拟条件从句中，如：
If only I had more money, I could buy a car!我要是有更多钱就好了，就可以买辆车了

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 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。
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：
二、虚拟语气的判断： 1. if 条件状语从句中虚拟语气的判断。if 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种： (1) 与过去事实相反的假设。结构为：从句的谓语动词用“had + 过去分词”，主句用“should (would, could, might) + have + 过去分词”。例如： If it had not rained so hard yesterday, we could have played tennis. 如果昨天没有下大雨，我们就能玩网球了。 (2) 与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should (would, could, might) + 动词原形”。例如： If I were in your position, I would marry her. 如果我是你，我就娶她为妻。 (3) 与将来事实相反的假设。结构为：从句的谓语动词用“should (were to) + 动词原形”，主句用“should (would, could, might) + 动词原形”。例如： If you should miss the chance, you would feel sorry for it. 如果你错过了这次机会，你会难过的。 2. 宾语从句中的虚拟语气。 (1) wish后接宾语从句中的虚拟语气：根据从句的意义来判断。 A: 表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如： I wish they were not so late. 要是他们来得不是这么晚就好了。 B: 表示与过去事实相反的愿望，从句谓语动词用过去完成时态。例如： I wished he hadn't done that. 我真希望那件事不是他做的。 (2) 表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气。用于此结构的动词有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest 等。从句的谓语动词用“should + 动词原形”，其中should 可以省去。例如： I insisted that he (should) go with us. 我坚持让他和我们一起去。 注意：当insist 表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。例如：
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：
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。
虚拟语气用法 虚拟语气用法
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）

高中英语虚拟语气的用法 一、考查虚拟语气在条件从句中的用法 时间从句谓语形式（be用were不可改变）主句谓语形式 将来一般过去时(be用were) would/should/might/could+动词原形 现在一般过去时(be用were) would/should/might/could+动词原形 过去现在完成时would/should/might/could+had done （1）If he my advice, he wouldn' t have lost his job. A. followed B. should follow C. had followed D. would follow （2）If we the other road, we might have arrived here in time for the meeting. A. taken B. had taken C. took D. have taken （3） -John went to the hospital alone. -If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 二、考查特殊句型中的虚拟语气 英语中需要使用虚拟语气的特殊句型不多，主理有以下类: 1.“倒装”类虚拟语气 当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。如: If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。. If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。 If we had found him earlier we could have saved his life.→Had we found him earlier we could have saved his life. 要是我们当时早点找到他的话,我们就可以救活他。 注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。如:我如不是警告了你,你就可能丧命了。 正: If I hadn' t warned you, you could have been killed. 正: Had I not warned you, you could have been killed. 误: Hadn' t I warned you, you could have been killed. 另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。 如: Had I time, I would go with you.假如我有时间,我就同你们一起去。句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you. (1) Had I known about this computer program, a huge amount of time and energy____. (2010浙江卷) A.would have been saved B. had been saved C. will be saved D. was saved （2） fired, your health care and other benefits will not be immediately cut off. (2006湖北） A. Would you be B. Should you be C. Could you be D. Might you be 2.“宁愿”类虚拟语气 这里说的“宁愿”主要是指would rather。当它后接句子的时候,句子的谓语通常要用虚
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。

英语虚拟语气用法详解 1. 英语语气的概念 英语有三种语气，即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等，祈使语气用于表示请求、命令或警告等，虚拟语气则表示假想或主观愿望。如： I like this book the best. 我最喜欢这本书。(陈述语气) Don’t be so careless. 不要如此粗心大意。(祈使语气) I suggest that we should go tomorrow. 我建议我们明天走。(虚拟语气) If you dropped the glass, it would break. 假如你把玻璃杯掉在地上，它会打碎的。(虚拟语气) 3. 虚拟条件句的基本类型 (1) 与现在事实相反：若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If we left now, we should arrive in good time. 假如我们现在就走的话，我们就会及时到达。 (2) 与过去事实相反：若与过去事实相反，条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, coul d, might)+have+过去分词”。如： If he had been in that train then, he might have been k illed in that accident. 如果当时他也在那列火车上，他可能就死于那场车祸了。
(3) 与将来事实相反：若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。(不过我不打算这样做) 3. 错综时间虚拟条件句 所谓错综时间虚拟条件句即条件从句与主句所指时间不一致，如从句指过去，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整。如：If you’d listened to me, you wouldn’t be in such tro uble now. 如果你听了我的话，你现在也不会有这样的麻烦了。 If you were in better health, we’d have let you go wit h us. 你要是身体好一点，我们就让你和我们一道去了。 4. 含蓄虚拟条件句 所谓含蓄虚拟条件句即指将条件从句隐藏在上下文一定的短语中的一类条件句。如： Anybody else would have believed you. 任何别人都会相信你的话了。 Without your help, I couldn’t have achieved all this. 要不是有你帮助，我不会取得这些成就。 I would have written before, but I have been ill. 我本想给你写信的，但我生病了。 5. if it weren’t (wasn’t) for与if it hadn’t been for
1．虚拟语气在条件句中的用法 （1）若表示与现在事实相反的假设，则条件从句中用过去式，主句中用过去将来式（would，should，could，might + 动词原形）；若表示某事将来实现的可能性不大，则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词。如： 2）若表示与过去事实相反的假设，从句中用过去完成式，主句中用过去将来完成式（should，would，could，might + have + 过去分词）。如： busy． （3）含有虚拟语气的条件状语从句中，如有had，should，were 这三个词的话，在正式或书面语言中可将if省略，再将句子的主语和谓语动词实行全部倒装或部分倒装。如： （4）若主句从句所指的时间不一致，即条件从句表示与过去事实相反，主句表示与现在事实相反；或者条件从句表示与现在事实相反，主句表真实情况，则从句中应采用与具体时间相对应的虚拟形式。如： 2．虚拟语气在宾语从句中的用法 在动词suggest，order，demand，propose，request，command，insist等后的宾语从句中，用虚拟语气（即Should+动词原形或只用动词原形）来表示愿望、建议、命令、请求等。在动词wish /would rather后的宾语从句中，用过去式表示与现在事实不符，用过去完成式表示与过去事实不符。如： 3．虚拟语气在主语从句中的用法 在It is necessary/important/strange/natural；It is requested/suggested/desired/proposed；it is a pity等结构后的主语从句中要用虚拟语气，即Should+动词原形或只用动词原形。如： 4．虚拟语气在表语从句、同位语从句中的用法。 在 suggestion， proposal，idea，plan，order，advice等名词后的表语从句、同位语从句中要用虚拟语气，即should+动词原形或只用动词原形 5．虚拟语气在其他状语从句中的用法 在as if引导的状语从句中，用过去式表示与现在事实不符，用过去完成式表示与过去事实不符；在so that，in order that引导的状语从句中，常用should/would/could/might+动词原形来表示虚拟语气。 6．虚拟语气在定语从句中的用法： 在it is time后面的定语从句中常用过去式表示虚拟语气。 虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。 Ⅰ用以表示虚拟条件的虚拟语气 ⒈ 用if条件从句表示的虚拟条件，是虚拟条件最普通的方式。 ① 虚拟现在时表示与现在事实相反的假设，其if 从句的谓语形式用动词的过
连云港育青外国语学校李老师谈英语中虚拟语气的用法 虚拟，在汉语中表示一种假设的，不存在的情况，同样，英语中虚拟语气是用来表示说话人 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。在初中阶段，虚拟语气一般用于下列情况： 一、条件状语从句 1、与现在事实相反 若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If I were you, I would take an umbrella. 如果我是你，我会带把伞。（事实上我不可能是你） If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。 (事实上我不知道) 2、与过去事实相反 若与过去事实相反，从句：主语+had done ，主句：主语+should/would/could/might+have done，例如： If I'd left sooner，I'd have been on time. 要是我早点动身，我就准时到了。(但我动身太迟了) If I had got 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） 3、与将来事实相反 从句：①if+主语+were to do 主句：①主语+should/would/could/might+do ②if+主语+did/were ②主语+should/would/could/might+do ③if+主语+should+do ③主语+should/would/could/might+do 例如：If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If he should come here tomorrow, I would talk to him. 如果他明天来这儿的话，我就跟他 谈谈。（事实：来的可能性很小） 注意与说明：对于与将来事实相反的情形，请注意以下几点： 一是这里说的与将来事实相反，实为对将来情况的推测； 二是此用法中的条件从句谓语除用过去式外，有时也用“should+动词原形”（ 表示可能性极小， 表示与将来事实相反的假设)； 常译为“万一”） 或“were to+动词原形”（ 三是当条件从句使用“should+动词原形”这样的谓语时，主句谓语除可用“should (would, could, might)+动词原形”这样的虚拟语气外，也可用陈述语气或祈使语气。如： I should see him, I'll tell him. 万一我见到他，我就告诉他。 万一明天下雨，就别等我了。 If it should rain tomorrow, don’t expect me. 二、wish 后宾语从句 1、表示与现在事实相反的愿望，谓语动词用过去式。例如： 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) 2、表示与过去事实相反的愿望，谓语动词：had+done 例如： I wish I had knownthe truth of the matter. 我希望我那时就知道这件事情的真相。（事实：那时还不知道） 3、表示将来难以实现的愿望，谓语动词：should/would（情态动词）+ 动词原形 I wish I should havea 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） 常见考法
