Question

【题目】

—Jenny took the 8:00 bus to Shanghai this morning.

—Really? She ______ the 9:00 train. It's much more comfortable and safer to travel by train.

A. could have taken B. should take

C. must have taken D. can take

Answer 1

【答案】A

【解析】 句意:——Jenny今天早晨乘坐8点的大巴去上海了。——真的吗？她本来能够坐9点的火车。坐火车会更舒适，也更安全。此句是对过去情况的相反假设,故用could have taken 表示“本来能够坐……”，而实际上没有坐。B和D项都是叙述现在或将来的情况; must have taken 用来对已发生的情况进行推测，不指与事实相反的情况。
