Question

【题目】Doctor Wang ________ at seven o’clock for the conference, but she didn’t turn up.

A.should have arrivedB.should arrive

C.should be arrivedD.should be arriving

Answer 1

【答案】A

【解析】

考查情态动词。句意：王医生本应该7点钟来参加会议的，但是她没有露面。根据后句but she didn’t turn up可知，句子是陈述过去的事情，对过去的推断应该用“情态动词+have done”。故选A。
