虚拟语气

一、回顾上单元的if虚拟语气,请填表格:
If 从句的谓语形式

主句的谓语形式

与现在事实相反

与过去事实相反

与将来事实相反

虚拟语气假设条件句型注意点：

1. If you _________ (listen) to the teacher carefully yesterday, you __________ (know) how to answer this question now.

2．If you_________(come) and attended the meeting yesterday, you __________ (know ) what we are doing now.

3．If you ___________ (follow) my advice, you ___________ (be) in trouble now.

★ 以上虚拟语气叫做错综条件虚拟语气，因为假设条件从句谓语动词发生的时间与主句所假设的谓语动词发生的时间不一致。主句和从句的谓语动词要依照它所表示的时间而定。

1. If I were you, I would give it up = __________________________________

2.If it were not for your advice, we couldn’t have got over the difficulties.

= ___________________________________________________________

3.If I had had time, I would have run round that lake again.

= ______________________________________________

4.If there should be a flood, what should we do = ____________________________

★以上虚拟语气是if省略的倒装句型。should，were，had三个助动词提至句首。

★虚拟语气特殊句型：

________________________________.　我希望和你一样高。

________________________________. 他希望他没讲那样的话。

________________________________. 我希望明下雨就好了。

①wish / if only/as if 现在：__________ 过去：____________ 未来：__________

②would rather that 现在/未来：___________ 过去：___________

④表示要求、命令、建议的词，即1.insist （坚决要求）、demand、require、 request 2. order, command 3. advise, suggest, propose ,recommend这些动词后面的宾语从句要使用虚拟语气用法。即从句中的动词使用should +v，或者将should省略。●以上动词相应的名词构成的从句也要使用虚拟语气。1.demand, request, reqirement 2.order, command 3.advice, suggestion, proposal, recommendation,

It is important that we _____________ (master) a foreign language.

二、本单元的学习重点：含蓄条件句
