Question

【題目】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】

考查情態(tài)動(dòng)詞。句意：王醫(yī)生本應(yīng)該7點(diǎn)鐘來參加會(huì)議的，但是她沒有露面。根據(jù)后句but she didn’t turn up可知，句子是陳述過去的事情，對(duì)過去的推斷應(yīng)該用“情態(tài)動(dòng)詞+have done”。故選A。
