例如：It's time you went to bed.（你该去睡觉了。

虚拟语气表示动作或状态与事实相反，或不可能发生的情况。

一．虚拟语气用于条件状语从句中1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。

Eg:If we had time now, we would read it again.If I were you, I would work hard.2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。

Eg:If he had taken my advice, he would have succeeded in the test.If I had known your telephone number then, I would have called you.3. 表示与将来的事实可能相反或不可能发生：条件状语从句：①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。

Eg:If it should rain, the crops would be saved.If it were to snow tomorrow, they would not go out.注：虚拟条件句的特殊情况(1)混合/错综型虚拟语气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，称为‘错综条件句’，动词的形式要根据它所表示的时间作出相应的调整。

Eg:If you had followed my advice, you would be better now.(从句说的是过去，主句是现在)Eg:If I were you, I would have taken his advice.(从句是现在，主句是过去)(2)省略if的虚拟语气如果从句中含有were/ should/ had时，则可以把这三个词置于句首，省略if.采用倒装语序。

英语虚拟语气知识点总结英语虚拟语气知识11、基础用法2. 注意四个情态动词的用法(1)若表示在某一假设的条件下，必然而然就会发生某事，第一人称可用should或would, 而二、三人称只用would.(2)若表示在某一假设条件下就能够干某事，各人称都用could.(3)如果表示在某种假设条件下有可能会发生某事，各人称都用might.3.虚拟语气的倒装当虚拟条件句中含有 were，had，should，could等动词时，可以将if省略，然后将 were，had，should，could等词移至句首。

注意：以上移至句首的 had不一定是助动词，如果是实义动词也可倒装：If he had money，he would buy a car. Hadhe money，hewould buy a car.(1)从句与过去事实相反相成，而主句与现在事实相反。

例如：If you had not been strict withme when I was young, I could not be such a successful person now.(这种虚拟语气的特点是主句中常含有时间准状语now或nowadays)(2)Should anyone come and ask for me, tell them I willcome back tomorrow.(主句为祈使句，条件句与将来事实相反，表示说话人认为某件事情发生的可能性很小。

)5.含蓄虚拟条件句含蓄虚拟条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。

这类用法主要见于以下七种方式：(1)将条件隐含在不定式短语中。

I should be happyto go with you. (=I should be happy if I could go with you.)(2)将条件隐含在分词短语中。

Born in bettertimes, he would have been a scholar. (=If he had been born in better times, he…)(3)将条件隐含在介词短语中。

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。
