虛擬語氣
一、回顧上單元的if虛擬語氣,請?zhí)畋砀?
If 從句的謂語形式
主句的謂語形式
與現(xiàn)在事實(shí)相反
與過去事實(shí)相反
與將來事實(shí)相反
虛擬語氣假設(shè)條件句型注意點(diǎn)：
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.
★ 以上虛擬語氣叫做錯(cuò)綜條件虛擬語氣，因?yàn)榧僭O(shè)條件從句謂語動(dòng)詞發(fā)生的時(shí)間與主句所假設(shè)的謂語動(dòng)詞發(fā)生的時(shí)間不一致。主句和從句的謂語動(dòng)詞要依照它所表示的時(shí)間而定。
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 = ____________________________
★以上虛擬語氣是if省略的倒裝句型。should，were，had三個(gè)助動(dòng)詞提至句首。
★虛擬語氣特殊句型：
________________________________. 我希望和你一樣高。
________________________________. 他希望他沒講那樣的話。
________________________________. 我希望明下雨就好了。

④表示要求、命令、建議的詞，即1.insist （堅(jiān)決要求）、demand、require、 request 2. order, command 3. advise, suggest, propose ,recommend這些動(dòng)詞后面的賓語從句要使用虛擬語氣用法。即從句中的動(dòng)詞使用should +v，或者將should省略。●以上動(dòng)詞相應(yīng)的名詞構(gòu)成的從句也要使用虛擬語氣。1.demand, request, reqirement 2.order, command 3.advice, suggestion, proposal, recommendation,
