Question

【题目】While waiting for the flight, your father his colleagues, but I am not sure.

A. might have met B. should have met

C. must have met D. could have met

Answer 1

【答案】A

【解析】考查情态动词。句意:在候机时,你的父亲可能见到了他的同事,但我不确定。由句中的"I am not sure可知,此处表示对过去发生的事情没有绝对把握的推测,故用might have done结构,表示"过去有可能发生……"。故选A。
