题目内容
The careless man received a ticket for speeding . He ____ have driven so fast .

A
解析试题分析：句意:那个粗心的人收到一张超速驾驶罚单。他本不应该开那么快。表示对过去的推测时用情态动词+have done sth. wouldn’t have done sth.用于虚拟语气； 故排除B。 mustn’t have done sth 没有这种形式，故排除D。can’t have done sth.过去不可能做某事，不符合句意，故排除C。shouldn’t have done sth表示过去本不应该做，但实际已经做了。故选A。
