Question

【题目】—I'm sorry. Linda is not at the office.

—She _______ have been away, because her car has not been at the outside of our company.

A.needB.couldC.willD.must

Answer 1

【答案】D

【解析】

句意：——很抱歉。琳达不在办公室。——她一定已经离开了，因为她的车已经不在我们公司外面了。

考查情态动词must表推测的用法。need需要；could可以，can的过去式，也可表示推测，意为“可能”；will将要；must必须，也可表示推测，意为“一定，肯定”。根据答语中后半句“because her car has not been at the outside of our company.”可知，此处是指她肯定已经离开了，表示非常有把握的推测。故选D。
