问题 选择题

––What a journey! We’ve finally arrived!

––_____ an out-of-date train schedule, we would not have missed the train.

A.Had we not used

B.Did we use

C.If we didn’t use

D.If we had used

答案

答案:A

题目分析:通过分析句子,可知其中包含一个虚拟条件句。根据主句“we would not have missed the train”可看出这是对过去情况的虚拟,所以条件句用过去完成时。又因为虚拟条件句中有had, should, were时,可以将if去掉,然后把had, should, were提到主语前面,故选A。

点评:注意区分真实条件句和虚拟条件句,真是条件句实现的可能性非常大,而虚拟条件句往往指不能实现的或纯属假想的情况。
