题目内容

9．-It rained cats and dogs this morning．I'm glad we took an umbrella．
-Yeah，we would have got wet all over if we ．（　　）

A．

hadn't

B．

haven't

C．

didn't

D．

don't

分析 --今早上下了倾盆大雨，我很高兴我们带了伞．
--是啊，如果我们没带的话，就全淋湿了．

解答答案：A．根据答语中主句的谓语动词"would have done"为"情态动词+have done（完成式）"可知，本句是与过去事实相反的虚拟．由此可推知，if从句中的谓语动词形式应用had done（过去完成式）来表示对过去情况的推测．故选A．

点评 if条件从句的虚拟情况有三种形式：如对现在情况假设：①if条件从句的谓语动词形式为过去式（be/were），主句的谓语动词形式为would/could/might/should do②如对过去情况假设：if条件从句的谓语动词形式为had done，主句的谓语动词形式为would/could/might/should do ③如对将来情况假设：if条件从句的谓语动词形式为were/did；should do；were to do，主句的谓语动词形式为would/could/might/should do．解此类题的关键是要判断对什么时间的假设，再而确定谓语动词形式．
