学士学位英语考试词汇练习及答案二十九

1. ____ you were busy, I wouldn’t have bothered you with my questions.

A.If I realized B. Had I realized

C.Did I have realized that D. As I realized

【答案】B 本题考察的是与过去事实相反的虚拟语气.条件状语从句谓语动词用had +过去分词,主句谓语动词用,should/would/could/might +have + 过去分词.当省略if 时,条件从句中的had 提前. 句意是“如果我意识到你这么忙,我就不拿我的这些问题来打扰你了.”

2. ___, I should ask them some questions.

A. Should they come to us B. If they come to us

C. Were they come to us D. Had they come to us

【答案】A 本题考查的是省略if的虚拟语气的用法。从句中的助动词had, were, should等要移至主语之前。如果他们来到我们身边，我会问他们一些问题。

3. Had the weather been good, the children ___ out for a walk.

A. had gone B. could have gone C. would go D. went

【答案】B。当虚拟语气中含有were, had, should, would等词时， 可以省略if, 把这些词放在主语之前。Should I meet her, I would tell her.万一我见到他， 我会告诉他的。Were I in your position, I would do it better.如果我处在你的位置上， 我会做的更好。Had they made preparations, they would have succeeded.如果他们准备了的话， 他们应该能成功的。本句为和过去的事实相反的虚拟语气，因此选B。

4. ___ today, he would get there for holiday.

A. Was he leaving B. Were he to leave C. Would he leave D. If he leaves

【答案】B。如果他今天走的话，他就在那里度假了。对将来的虚拟。

5. We ___ our lives had it not been for the policeman.

A. would have lost B. should lose C. might lose D. could have lost

【答案】A。要不是警察，我们都已经没命了。从句对过去，主句对现在。

6. He was very busy yesterday; otherwise he______ to the meeting.

A. would have come B. would come C. could come D. had come

【答案】A 本句考察虚拟语气。“如果他不是很忙的话，昨天就去开会了”，事实是他没有去开会，所以是与过去事实相反的假设，主句应该用过去将来完成时，因此选A项would have come.

7. Without your help, we ____ so much.

A. didn’t achieve B. would not have achieved C. will not achieve D. don’t achieve

【答案】B 本题考察的是虚拟语气. without your help = if you had not helped us,表示与过去事实相反,主句谓语动词用should/would/could/might + 动词原形.故选B. 句意是“如果不是你帮助我们,我们就不会取得这么大的成就.”

8. Something must have happened on their way here. Or they ___ by now.

A. should have arrived B. should arrive C. would have arrived D. would arrive

【答案】C。第一句是must+have +过去分词的结构，表示对过去事实的推测。The road is wet. It must have rained last night.路是湿的，昨晚上肯定下雨了。因此我们可以推断：这是一个和过去的事实相反的虚拟语气。should +have +过去分词的结构，表示对过去动作的责备、批评。如：You should have gone over your lessons.你应当把功课复习好的。但是此句只是一个表示和过去的事实相反的虚拟句子，并没有责备的意思。本句的意思是：“路上肯定出事了。否则，他们现在已经到了。”因此正确答案应该是C.

9. But for the rain, we ____ a nice holiday.

A. should have B. would have had C. would have D. will have had

【答案】B 这是含蓄条件句，表示“如果不……则我们已经……了”，故选B。but for：如果不是因为……，要不是……。句意为：如果不是因为下雨，我们本可以好好度假。Would have done 表示对过去事实的虚拟。

10. But for my classmates’ help, I ___the work in time.

A. did not finish B. could not finish

C. will not finish D. would not have finished

【答案】D 此句是含有含蓄条件句“but for my classmate's help"的句子.因此要选择一个虚拟语气的句子。因为是和过去的事实相反,因此D为正确答案。本句的意思是：“要不是同学们的帮助.我是不会按时完成任务的

11. If you_____ that late movie last night, you wouldn’t be so sleepy.

A. hadn’t watched B. haven’t watched

C. wouldn’t have watched D. didn’t watch

【答案】A 此题考察虚拟语气，假设“如果你昨晚没看那场电影”，事实是看了，因此句意与过去事实相反，用过去完成时。

12. If he ___ to the teacher attentively, he ___ the answer to the problem now.

A. had listened, would have known B. listened, would know

C. listened, would have known D. had listened, would know

【答案】D。如果他认真听了课，他就会知道这个问题的答案了。错综虚拟语气，前半句对过去，后半句对现在。
