Question

—Jenny took the 8： 00 bus to Guangzhou 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

A

【解析】A 考察情态动词。句义：Jenny今天早晨乘坐8点钟的汽车去了广州。真的吗？她本可以乘坐9点的火车的。那更舒服安全。根据语境和句中的时态，可知是对过去情况的说明。应该使用情态动词的完成式。Could have done本可以做某事。故A正确。
