虚拟语气的定义是啥?
虚拟语气讲解及练习
一．非真实条件句的虚拟情况:
句型 条件从句 主句
对现在的虚拟 were/did should/would/could/might+v.
对过去的虚拟 had done should/would/could/might+ have+done
对将来的虚拟 1.were/did
2.were to
3.should+v.
Should/would/could/might+v.
1. If I were you, I would go at once.
2. If you had come a few minutes earlier, you would have met him.
If she had told him about the danger, he would not have hurt.
3. If it were sunny tomorrow, I would come to see you.
If he should fail in the experiment this time, he would try again.
4.混合时间条件句：主从句不一定用指同一时间的动词。主句和从句的谓语动词要依照假设的时间而定。
If Paul had received six more votes in the last election, he would be our chairman now.
If you had followed the teacher’s advice, you wouldn’t be in the hospital.
If you ____that late movie last night, you wouldn’t be so sleepy.
A. haven’t watched B.didn’t watch C. hadn’t watched D.wouldn’t watched
5．含蓄条件句：有时假设的条件不通过条件从句表示而含蓄在介词短语或上下文中。
(1) without 和but for (要不是) 构成虚拟。
Without ( but for ) the party, we wouldn’t be so happy.
We might have died without your help. = We might have died if you hadn’t helped us.
(2) otherwise , or ( 否则， 要不然) =if…not…
He studies very hard, or/otherwise he couldn’t study so well.
I was busy last week, otherwise I would have come to see you.
=If I had not been so busy last week, I would have come to see you.
( 3 ) if only后加句子… “要是……就好了”
If only I could learn English in one day. If only Jim had passed the exam.
★．假设虚拟条件倒装。 条件从句中有 should, were, had 三词，把 if 省略，将这三个词提到句首
If I were you, I would give it up. Were I you, I would give it up.
If she had told him about the danger, he would not have hurt.
Had she told him about the danger, he would not have hurt.
二．虚拟语气用于宾语从句中。
1. wish引起的表示愿望的虚拟语气

※ 当suggest表暗示，insist 表坚持说的时候，从句不用虚拟语气。
