三、 虚拟语气假设条件句型注意点： 1. 错综条件虚拟语气，主句和从句的谓语动词要依照假设的时间而定。 If the weather had been finer, the crops would be growing still better. If you had followed the teacher’s advice, you wouldn’t be in the hospital. 陈述语气与虚拟语气 典型例题 1) The volleyball match will be put off if it _____.
A. will rain B. rains C. rained D. is rained
2) --- Would you have called her up _____ possible?
--- Yes, but I _____ busy doing my homework.
A. had it been … was
B. if it was … were
C. if it had been … had been
D. if it were … would be
B 该句为陈述语气，因为主句用的是 will be put off。真实条件句主句为将来时，从句用一般现在时代将来时。 问句中用的是虚拟语气，主句用 would have called, 从句中与过去相反的动词形式为 had done；答句中表示的是真实的情况，所以该用陈述语气。 A 高考题点击 3) You didn’t let me drive. If we ____ in turn, you ____ so tired.
A. drove…didn’t get B. had driven…wouldn’t have got
C. drove…wouldn’t get
D. were driving…wouldn’t get
4) It is hard for me to imagine what I would be doing today if
I _____ in love, at the age of seven, with the Melinda Cox
Library in my hometown. (02 上海)
A. wouldn’t have fallen
B. had not fallen
C. should fall
D. were to fall 前句用的是陈述语气，表示过去发生的事；后句是虚拟语气，表示与过去相反。 B B 该句主句中用的是与现在相反的虚拟语气，而从句中使用的是与过去相反的虚拟语气。全句意思为“如果我不在七岁时迷上了我们家乡的 Melinda Cox Library，我真不能想象我今天会做什么。”
