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。
高考英语复习知识点：情态动词和虚拟语气及英语作文结尾万能公式
高考英语复习知识点：情态动词和虚拟语气及英语作文结尾万能公式高考英语复习知识点：情态动词和虚拟语气虚拟语气在高考命题中不是重点，但是难点。
考点常集中在含蓄条件句以及主语、宾语从句等特定句型中虚拟语气的使用上，因此考生应熟练掌握含蓄条件句中主从句的时态要求以及一些典型句型中虚拟语气的具体形式。
虚拟语气考点透析考点一、虚拟语气的基本用法1.与现在事实相反的虚拟语气，基本结构为：主语+动词的一般过去时(be动词用were)+其他成分+if+should/would/could...+动词原形+其他成分。
例如：①If it were not for the fact that she ______ sing，I would invite her to the party.A.couldntB.shouldntC.cantD.might not解析句意为：如果不是因为她不会唱歌的事实，我会邀请她来参加那次聚会的。
that从句为同位语从句，描述的是事实，用陈述语气。
正确答案为C。
2.与过去事实相反的虚拟语气，基本结构为：主语+动词的过去完成时+其他成分+if+should/would/could...+have done+其他成分。
例如：If the weather had been better，we could have had a picnic.But it ______ all day.A.rainedB.rainsC.has rainedD.is raining解析句意为：如果天气好的话，我们是能够去野餐的，但是下了一天的雨。
句子前半部分陈述的是与过去事实相反的事情，所以用了虚拟语气。
下了一天的雨是事实，所以用陈述语气。
因为是发生在过去的事实，所以正确答案为A。
3.与将来事实相反的虚拟语气，基本结构为：主语+动词的一般过去时/should do/were to do+其他成分+if+should/would/could...+动词原形+其他成分。

一.概念语气有三种: 陈述语气、祈使语气和虚拟语气。
语气表示说话人对劝词所示的动作或所处的状态持有的态度或看法。
二.相关知识点精讲1、辨别if 引导真实条件句和if引导的虚拟条件句的区别If he has time, he will go with us.= Probably he has time and will go with us.If he had time, he would go with us.=But in fact he has no time.2、虚拟条件句: 1)主句和从句的谓与动词构成形式如下表移除2)混合时间的虚拟语气如果条件句中的动作和主句的动作不是同时发生，主句和从句的谓语动词的形式应分别根据各自所表示的时间加以调整。
1)If he had telephoned me last night, I would see him now.2)If he had followed the doctor’s advice, he would be all right now.3)If China had not been liberated, the working people would still be leading a miserable life.3）隐含条件虚拟语气without；but for；except for；“if it were not for +宾语”或“were it not for + 宾语”；But that + 从句；主句谓语用虚拟语气，时态变化同上表。
4)倒装省略句如果虚拟语气的条件从句谓语动词中含有were, had, should，could有时可将if省去，而将条件从句的主语置于were, had, should, could之后。
高中英语语法-虚拟语气全总结
高中英语语法-虚拟语气全总结虚拟语气通常用于表达与现实相反的假设情况。
在非真实条件句中，虚拟语气的形式有两种：与现在事实相反的假设和与过去或将来事实相反的假设。
与现在事实相反的假设通常使用if+主语+助动词的过去式（如were。
did。
had）+动词原形，主句则使用XXX动词原形。
例如：If I had time。
I would XXX。
如果我有时间，我会参加会议。
与过去或将来事实相反的假设则有三种形式：①if+主语+动词过去式；②if+主语+wereto+动词原形；③if+主语+should+动词原形（注意不能是would）。
主句同样使用XXX动词原形。
例如：If you had taken my advice。
you would not have failed in the exam。
如果你听了我的建议，你就不会在考试中失败了。
在错综时间条件句中，动词形式要根据表示时间的状语从句作出相应的调整。
另外，在条件句中可以省略if，把were、had、should提到句首，变成倒装句式。
例如：Were I at school again。
I would study harder。
如果我还有上学的机会，我会更加努力研究。
Had you arrived earlier。
you would have caught the bus.If it rains tomorrow。
XXX climbing.What would you do with a n dollars?We couldn't have finished the work ahead of time without your help.Otherwise。
I would have taken part in the sports meeting.XXX me of your birthday。
or else I would have known nothing about it.A man who s drinking water would be dead in about seven days.I might have been XXX assistance。
