My English-Chinese dictionary has disappeared. Who _____ have taken it?

A.should

B.must

C.could

D.would

答案及解析: C

考查情态动词表示推测。根据问句可以看出语气不肯定,所以B排除。should have taken表示“本该拿(实际未拿)”,would have taken“本来会(但没有),均不合题意,可排除。情态动词could在交际用语中常表示语气的委婉,而不表示过去时,如:— Could you tell me the way to the supermarket? — Sure.(注意不能用Yes, I could.或No, I couldn’t.来回答)
