题目

题型：不详难度：来源：

—Fined ￥100! You know you were driving 100 KM an hour, don"t you?
—No, officer. I _____．This car doesn"t do 80．

A．shouldn"t have been	B．mustn"t have been
C．can"t have been	D．mightn"t have been

答案

C

解析

试题分析：shouldn’t have done本不应该做某事，实际上却做了；can’t have done不可能做了某事；mightn’t have done也许没有做某事。不存在mustn’t have done的结构。句义：—罚款100元！你知道刚才你的车速是100公里每小时吗？—不。警官，我不可能那样的。这辆汽车开不到80码的。根据句义说明C正确。
