—Fined ￥100! You know you were driving 1

问题选择题

—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

答案：C

题目分析：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。
