高中英语语法虚拟语气详解及练习
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。

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。

虚拟语气英语有两种语气——陈述语气和虚拟语气。
陈述语气表示事实上发生的事情或客观存在的情况。
虚拟语气表示假定、想象、愿望等非事实观念。
Ⅰ.虚拟语气在条件句中主要有以下几种情况。
(1).表达与现在的事实相反的假设或想象：条件从句主句If + 主语+ 过去式，主语+ should/would + 动词原形If + 主语+ were，主语+ would/should + 动词原形(其中，should用于第一人称，would可用于各个人称。
)If I had enough money, I should/would buy a camera.If I were rich, I would help the poor.(2).表达与过去事实相反的假设或想象：条件从句主句If + 主语+ had + 过去分词，主语+ should/would have + 过去分词If I had had enough money, I would have bought a car.（= I didn’t have enough money, so I didn’t buy it.）If it had not rained yesterday, we should have gone fishing.(3)表达与将来事实相反的假设或想象，有三种形式：①条件从句主句If +主语+ should + 动词原形，主语+ should/would + 动词原形(表示可能性极小“万一”)If it should rain tomorrow, I would not go.注意：if从句的动词形式不分人称与数，一律用“should+动词原形”②条件从句主句If +主语+ were to + 动词原形，主语+ should/would +动词原形If I were to go abroad, I would go to America. 倘若我要出国，我就到美国。
③条件从句主句If +主语+动词过去式，主语+ should/would +动词原形If he went to the party, he would be disappointed.(4)在条件状语从句中，常会出现主句所表示的行为所发生的时间与从句表示的行为的时间不一致，叫做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，而主句却指现在或将来，此时应根据具体的语境，结合上面提到的三种基本类型对时态作出相应的调整。
If you had gone to bed early last night, you would not be so sleepy now.If I were you, I wouldn’t have gone to the party last night.(5) 假设情况不用if从句来表示，而是用without, but for, otherwise, or, but等表示一种含蓄条件。
表示与现在或将来相反，用“would (should, could, might)+动词原形”；表示与过去相反用“w ould (should, could, might)+have+过去分词”I knew my uncle did have no time. Otherwise he would have kept me company to go hiking.例1：We ______ John's name on the race list yesterday but for his recent injury. (2011·江西卷28)A. will putB. will have putC. would putD. would have put例2: I ______ through that bitter period without your generous help. (2011·陕西卷22)A. couldn't have goneB. didn't goC. wouldn't goD. hadn't gone(5)条件从句if的省略：当从句中有were，过去分词had, 或should时，if经常省略。
此时，主语后面的主动词（were，had，should 等）被移至句首。
Were I a bird, I would fly to you.= If I were a bird, I would fly to you,Should it rain tomorrow, I would not go there.= If it should rain tomorrow, I would not go there.例:______ in your position, I would go.A. If IB. Were IC. If was ID. If I amⅡ用在从句中的虚拟语气⒈宾语从句中的应用（1）wish后的宾语从句：表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；表示与过去相反的愿望，从句谓语用过去完成时；表示将来没有把握或不太可能实现的主观愿望，常用“would (could)+动词原形”。
I wish I knew the answer to the question..I wished I hadn’t spent so much money.I wish it would stop raining.I wish you would come soon.例：—Where are the children?—I wish they ______ always late. (2011·北京卷28)A. weren'tB. hadn't beenC. wouldn't beD. wouldn't have been(2) 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气。
谓语动词用(should) +动词原形。
值得注意的是，如果宾语从句的动词是否定的，否定词not的位置应在动词之前，而不是动词之后。
I demand that he (should) answer me immediately.The head nurse insisted that the patient not be move.【注意】(1)suggest 意为“表明，暗示”时，宾语从句不用虚拟语气.His pale face suggested that he was in poor health.(2)insist 意为“坚持认为，坚持说”时，宾语从句不用虚拟语气。
He insisted that he did not kill the boy.2. 主语从句中的应用It is+形容词/ 名词/ 过去分词+ that引导的主语从句，主语从句中谓语动词常用“should + 动词原形”。

常用过去分词有：demanded, suggested, required, requested, ordered, decided等It is suggested that pupils (should) wear school uniforms.It is important that everyone (should) inform themselves of these rules.It is a pity that he (should) refuse to accept the offer3.表语从句中的应用上述动词相应的名词形式作主语+连系动词构成表语从句，要用虚拟语气，即“should + 动词原形”.常用名词形式有：advice, decision, demand, proposal, request, order, suggestion等。
His suggestion was that the meeting (should) be put off.Ⅲ其他形式的虚拟语气1. 在It's (high/about) time “该干某事了” 之后的定语从句中需用虚拟语气。
谓语动词用过去式.It is high time that you went to school.2. 虚拟语气在as if / as though 引导的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）表示与现在事实相反，从句谓语用一般过去时或过去进行时；表示与过去事实相反，用过去完成时；表示将来的可能性不大，用“would (could)+动词原形”He felt as if he were responsible for what had happened.He treats me as if I were a stranger.Even if she had been ill, she would have gone to her office.3.if only 引起的感叹句中需用虚拟语气表示与现在或未来事情相反的愿望，谓语动词用过去式或would/should+动词原形表示与过去事实相反的愿望，谓语动词用过去完成式。
Look at the terrible situation I am in! If only I had followed your advice.If only I had not been busy last week.4. would （had）rather , would sooner也用来表达主观愿望，它们之后的宾语从句中需用虚拟语气。
