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––_____ an out-of-date train schedule, we would not have missed the train.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

A

解析

试题分析：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。
