虚拟语气语法总结笔记

1）虚拟语气的标志词：

一坚持insist

两命令order/command

三建议advise/suggest/recommend

四要求ask/require/request/demand

❗️后面加should do

2）特殊用法：

suggest表示建议的时候，后面要用虚拟语气；suggest表示暗示，表明的时候，后面不用虚拟语气

insist表示坚持要求做（动作尚未发生）的时候，后面要用虚拟语气；insist表示坚持认为某种观点，看法，事实（动作已经发生）的时候，后面不用虚拟语气

1）与现在事实相反

从句是：if sb.+did

主句是：sb.+would+do

🌰:If I were you, I would reconsider their advice.

2）与过去事实相反：

从句是：if sb.+had done

主句是：sb.+would+do

🌰:You should not have caught a cold if you had put on more clothes.

3）与未来事实相反：

从句是：if sb.+were to do（be to do 近似于should do是将来时的表达方法） / should do

主句是：sb.+would+do

🌰:If I were to do it, I would do it in different way.

❗️在非正式文体中，如果if- clause中有were/should/had可以把它放到主语之前，省略if，形成部分倒装

🌰：Were I you=If I were you

从句是过去完成时用had done，主句用过去将来时would do；

从句用should/were to，主过将完用would have done

It‘s high/about/the very/quiet time that +定语从句+did/should do（should do带有主观色彩）
