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。

高中英语语法-虚拟语气全总结
虚拟语气在非真实条件句中①错综时间条件句: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表示的时间作出相应的调整。
如：If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。
如：If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会，我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点，你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话，我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如：What would you do with a million dollars? (=if you had a million dollars)如果你有100万元，你会做什么？We couldn’t have finished the work ahead of time without your help. (=if we hadn’t got your help) 没有你的帮助，我们不可能提前完成这项工作。
