Question

【題目】She looks very happy. She_________ the exam.

A.can have passedB.should have passedC.must have passedD.could have passed

Answer 1

【答案】C

【解析】

考查情態(tài)動詞。句意；她看起來很高興。她一定通過了考試。must /could+ have done表示對過去發(fā)生的事情的推測，意為“一定/可能（已經(jīng)）… ”，本句中根據(jù)語境She looks very happy可判斷，用 must have passed語氣較強，意為“一定是已經(jīng)通過了（考試）”，故排除D項，選C。
