题目
题型:不详难度:来源:
He _____ have fallen asleep last night because he didn’t hear the phone call.
A.mayB.shouldC.canD.must

答案
D
解析

试题分析:考查情态动词表示推测。对现在情况表示推测使用“情态动词+动词原形”;对过去情况进行推测,使用“情态动词+have done”;本题根据didn’t hear…说明是对过去情况的推测。Must have done一定做了;may have done也许做了某事;should have done本应该做某事(实际上却未做)(表示虚拟语气);句意:他昨天晚上一定睡着了,因为他没有听见电话铃声。故D正确。
点评:对现在情况表示推测使用“情态动词+动词原形”;对过去情况进行推测,使用“情态动词+have done”;本题的Must have done一定做了;
