Question

【题目】Cathy has to do the same thing every day. She ________ be very bored with her job.

A.canB.mustC.oughtD.need

Answer 1

【答案】B

【解析】

句意：凯西每天都要做同样的事。她一定对她的工作很厌烦。

考查情态动词。can能；must必须，一定；ought应该，缺少to；need需要；根据句意理解及前句Cathy has to do the same thing every day.可知，这里表达的是一种推测，表示“一定很厌烦”，表示肯定推测的是must，故选B。
