　　【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.”

　　18. 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。

　　21. 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.

　　22. 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.”

　　23. 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.

　　24. 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。

　　25. 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
