题型:不详难度:来源:
It ___________last night, for the ground is wet outside.
A.would be rainingB.would have rainedC.must rain D.must have rained

答案
D
解析

试题分析:考查情态动词表示推测。句意:昨天晚上肯定下雨了,因为外面的地上是湿的。根据句意说明是对过去情态的推测,使用“情态动词+have done”的形式;如果是对现在的情况进行推测,要使用“情态动词+动词原形”的形式。Must have done一定做了某事;would have done本要做某事,实际上却未做(表示虚拟语气)。故D正确。
点评:情态动词的用法比较复杂。突出的是表示推测:如果是对现在的情况进行推测,使用“情态动词+动词原形”;对过去的情况进行推测,使用“情态动词+have done”;情态动词也经常用于虚拟语气,要分具体情况来分析,在条件句中和宾语从句,表语从句中都有体现。
