高中英语2025届高考语法复习虚拟语气知识讲解
高考英语语法复习虚拟语气知识讲解一、基础知识（一）什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设（情感），也是一种语气（mood)的表现形式，表明说话的目的和意图。
（语气包含陈述语气、祈使语气、虚拟语气、疑问语气）虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况，即与真实相反。
上学的时候老师经常举的一个例子，"If I were you"因为我不可能是你，这是一种不可能存在的事实，所以这是个虚拟语句。
总而言之英语中的虚拟语气可以分为两大体系：一是表示与事实相反的，或者是假象的情形，通常由if引导，叫做虚拟条件句；另一个体系是在名词从句中使用虚拟语气，表示建议，命令或者要求等语气，类似于上述美剧常用的台词。
（二）虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解与现在事实相反：If I had a map, I would lend it to you.如果我有地图我就借给你。
（但我没有）与将来事实相反：If I were to do the job, I would do it in a different way. 要是我来做这工作，我会是另一种做法。
（言外之意不是我做这个工作，用虚拟表达是我做这份工作的可能性很低）与过去事实相反：If anything had happened, he would have let us know.如果发生了什么情况，他早就通知我们了。
（所以没事发生）它们的共性都是表示与事实相反或者实现可能性不大3.特殊情况①在极少情况下，从句的谓语动词用原形，主句的谓语动词可用陈述语气（比较官方，正式，大气的说法，口语很少使用）If that be the official view, it cannot be accepted.如果这是官方的看法，这是不能接受的。
②if可以省略，但是语序要改为倒装Were I Tom I would refuse.如果我是汤姆我会拒绝。

虚拟语气的基本容【开头引入】If 如果(如果有两种可能,有可能发生的，不可能发生的。
)①有可能发生If it rains tomorrow, I will not go to the park.②不可能发生虚拟语气，例如，如果我是明，。
虚拟语气表示说话人的愿望，假设，猜测或建议，而不表示客观存在的事实。
所以，凡表示与事实不符的假设，想象，愿望时，需用虚拟语气表达。
一、If 引导的虚拟（一）If 引导的虚拟语气,可用下表表示。
①与现在事实相反：If I had wings, I would fly over the sea.②If she were rich, she would buy a bigger house.If there were no gravity, we would not be able to walk on the earth.②与过去事实相反：If You had gone to the party, You would have seen YaoMing.If you had taken my advice, you would not have failed in the exam.③与将来事实相反：If he were to tomorrow, We would have the meeting.If he should come tomorrow, We could go to the park together.If there were a heavy snow next Monday, we would not go skating.（二）if虚拟语气条件句的省略倒装。
如果虚拟条件从句中有were, had, should,可把if 省略，把were, had, should 提到主语前面，成为倒装结构。
①If I were you, I would accept the challenges.----Were I you, I would accept the challenges②If you had informed me earlier, I wouldn’t have signed the contract.----Had you informed me earlier, I wouldn’t have signed the contract.③If she should be my daughter, I wouldn’t allow her to study abroad.----Should she be my daughter, I wouldn’t allow her to study abroad.要不是…”①Were it not for your help, I would never be a good boss.要不是你的帮助，我永远成不了一个好的老板。
②Had it not been for you, I would have lost my way.当时要不是你，我就迷路了。
**如果谓语动词是否定形式，不能用动词的缩略形式。

例如：①If you had followed my advice just now, you would be better now.如果你刚才听了我的建议，你现在就好多了。
②If you had studied hard before, you would be a college student now.如果你以前好好学习的话，你现在就是大学生了。
③If he were free today, we would have sent him to Beijing.如果他今天方便的话，我们就可以把他送到去了。

If the United States had built more homes for the poor in 1995, the housing problems now in some parts of this country __________ so serious.A. wouldn’t beB. won’t beC. will not have beenD. would not have been三、含蓄条件句。
有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件从句，而是通过介词短语，副词，连词替代来代替条件从句。
例如：1. 如果没有你的帮助，我们不可能提前完成任务。
If it had not been for your help, we couldn’t have finished the work ahead of time.➢Had it not been for your help, …➢Without/ But for your help……2.我那天生病了，否则，我就参加运动会了。
If I had not been ill that day, I would have taken part in the sports meeting.➢I would have taken part in the sports meeting, but I was ill that day.➢I was ill that day. Otherwise, I would have taken part in the sports meeting.四、特殊句式1. 馒头-面条原理用于表示建议，决定，命令等词语后的that-从句①用在suggest(建议)，insist(坚决要求)，order(命令，下令)，advise(劝告，忠告)，propose(提议，建议)，recommend(劝告，建议)和require(法规要求，规定)等动词之后的that-宾语从句中，从句谓语动词用（should）+动词原形。
1.He suggested that we (should) start off early the next day.2.They insisted that the boy (should) go with them.3.He advised that she (should) wait for a few weeks.4.We proposed that someone neutral (should) take the chair.5.Teachers recommend parents (should) not allow their children under 12 to ride bicyclesto school for safety.注意：当suggest 表示“暗示”，“表明”之意，insist表示“坚持认为”，后面的宾语从句不用虚拟语气。
