高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。
虚构语气一、考点聚焦1、虚构语气用于条件状语从句中（ 1）表示与此刻事实相反的假定，条件状语从句中的谓语动词用“过去式（b e 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达成时，主句中的谓语动词则用“would / should / might / could + have +过去分词”。
如：（3）表示与未来事实相反，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，动词的形式要依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，主句指的是此刻 )以下表格是虚构语气用于条件状语从句中时，主句和从句谓语动词的形式：有时侯在使用时可省略 if,句子则可换成以下形式，即“were / had / should + 主语”。
如：Were I a boy, I would join the army.1/14Were it not for the expense, I would go to .2、虚气用于名性从句（ 1）虚气在从句中的运用。
①“ wish + 从句”表示不可以的梦想，“假如⋯⋯就好了”等。

高中英语虚拟语气详解及练习（含答案）虚拟语气第一节语气英语的动词一般可带有三种不同的语气：陈述语气（Indicative Mood），祈使语气(Imperative Mood)和虚拟语气（Subjunctive Mood）。
不同的语气用动词的不同形式（有的还借助句法形式）来表示。
第二节虚拟语气的概念虚拟语气是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等(在宾语从句、表语从句、同位语从句)。
第三节虚拟语气在条件句中１．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所表示的时间作出相应的调整．If you had followed my advice , you would be better now.如果你听我的建议，你现在就会痊愈了．２．在条件句中，可省略if，把were ,had, should 提到句首，变为倒装句式．If you had come earlier, you would have met him.第四节虚拟语气在名词从句中的运用一、虚拟语气在主语从句中A.在句型“It is important (necessary, strange, natural) that .... ”中，表示某事重要、奇怪、自然、必要等；that 后面的从句中的谓语动词用：should + 动词原形（should可以省略）例如：It’s important that we should take good care of the patient. 重要的是我们要照顾好病人。
这类的形容词还有advisable（可取的），appropriate（适当的），compulsary（必须的），crucial（关键的），desirable（理想的），essential（必要的），imperative（迫切的），important(重要的)，possible （可能的），preferable（更好的），probable（可能的），strange（奇怪的），urgent（急迫的），vital （极为重要的）等。

虚拟语气一、知识框架二、知识梳理（一）语气的定义和种类l、语气：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：(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 not ready. 我们没准备好。
What a fine day it is!多好的天气啊!(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。
请打开门。
(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. 如果我是你，我就学英语了。
May you succeed! 祝您成功！（二）虚拟语气在条件从句中的用法条件句有两类，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，就是真实条件何。
在这种真实条件句中的谓语用陈述语气。
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。
If it doesn't rain tomorrow, we will go to the park.If he had seen you yesterday, he would have asked you about it. (事实上他昨天没见到你，因此也未能问你这件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语气。

高考英语虚拟语气讲解及练习英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
虚拟语气表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。
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的或实际可能性不大的情况，故采用虚拟语气。
如果假设的情况可能发生，是真实条件句，这种情况下谓语用陈述语气。
如：If time permits, we'll go fishing together.如果时间允许，我们就一起去钓鱼。
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。
如：If you had come yesterday, you would have met that famous professor.如果你昨天来，你就会见到那位著名的教授了。
虚拟语气的基本形式和用法在含有虚拟条件句的复合句中，主从句的谓语都要用虚拟语气。
I. 含有条件状语从句的复合句If I were you, I would give up drinking immediately.If I were to see her tomorrow, I would tell her the truth.If you went there next time, you would see what I mean.country.注意事项：1．倒装句。
如果条件句中含有功能词had，should，were时，可以省去If，把功能词提前，构成倒装句。
2．错综条件句。
若条件句和主句动作不存在同一个时间，则谓语形式应根据具体情况而定。
If he had followed the doctor’s advice, he would be quite all right now.If I were you, I would have gone home.3．If there weren't/had not been +…=without…4．If it were not for…/ If it hadn't been for…= but for…5．otherwise+虚拟语气的句子II. 虚拟语气用在宾语从句中sb. did …(希望现在用过去式)1. wish+that sb. had done…（希望过去用过去完成式）sb. would/should do（希望将来用过去将来）2. would rather后的从句要用虚拟语气。

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。
作表示建议、要求、命令等的名词advise、idea、order、demand、plan、proposal、suggestion、request等的表语从句和同位语从句，从句中的谓语动词用“（should）+ 动词原形”。
如：His suggestion that we (should)go to Shanghai is wonderful.My idea is that they (should)pay 100 dollars.（3）虚拟语气在主语从句中的运用。
在主语从句中，谓语动词的虚拟语气用“should + 动词原形”的结构，表示惊奇、不相信、理应如此等。
如：It is necessary(important, natural, strange, etc.)that we should clean the room every day.It was a pity (a shame, no wonder, etc.)that you should be so careless.It will be desired(suggested, decided, ordered, requested, proposed, etc.)that she should finish her homework this afternoon.注意：这种从句表示的是事实。
如果说人对这种事实表现出惊奇的情感，就可用虚拟语气。
反之，如果不表示惊奇等情感，that从句也可用陈述句语气。
如：It is pity that you can’t swim.3、虚拟语气在其他场合的运用（1）虚拟语气在as if/as though、even if/even though等引导的表语从句或状语从句中，如果从句表示的动作发生在过去，用过去完成时；指现在状况，则用一般过去时；指将来状况则用过去将来时。
如：He did it as if he were an expert.Even if she were here, she could not solve the problem.（2）虚拟语气用于定语从句中。
这种从句常用于句型“It is (high)time (that) … ”中，定语从句的谓语动词用一般过去时(be用were)或should + 动词原形，意思是“(现在)该……”。
如：It’s time that I picked up my daughter.It’s high time we were going.（3）虚拟语气用在if only引导的感叹句中。
如：If only I were a bird.If only I had taken his advice.（4）虚拟语气在一些简单句中的运用。
①情态动词的过去式用于现在时态时，表示说话人谦虚、客气、有礼貌或语气委婉，常出现在日常会话中。
如：It would be better for you not to stay up too late.Would you be kind enough to close the door?②用于一些习惯表达法中。
如：Would you like a cup of tea?I would rather not tell you.二、精典名题导解选择填空1. When a pencil is partly in a glass of water, it looks as if it _______. (NMET 95)A.breaksB.has brokenC.were brokenD.had been broken解析：答案为C。
本题考查的是as if 引导的让步状语从句中的语气问题，as if引导的状语从句如果与事实一致，不用虚拟语气，如果与事实相反，应用虚拟语气。
题中“当铅笔的一部分浸在水中，铅笔看上去好像断了”。
而实际上铅笔并未断，与事实相反，前半部分陈述是一般现在时，因而本句是对一般现在时的虚拟，用were broken。
2. I didn’t see your sister at the meeting. If she ___________, she would have met my brother.(NMET 94)A.has comeB.did comeC.cameD.had come解析：答案为D。
本题考查的是if条件句中的虚拟语气。
题意是：我在会议上没看到你姐姐，故你姐姐没来。
因此如果“她来了”与事实相反，前面一句交代了虚拟语气的时态是一般过去时的虚拟，所以if从句中用had+过去分词。
3. —If he ___________, he ________that food.—Luckily he was sent to the hospital immediately.(NMET 93)A.was warned; would not takeB.had been warned; would not have takenC.would be warned; had not takenD.would have been warned; had not taken解析：答案为B。
本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。
根据下一句语境可知，他事先并没有得到警告，表示过去时间的虚拟语气，故选B。
