Question

His brother met him at the Great Theatre yesterday afternoon, so he ____ have attended your lecture.

A．couldn’t

B．needn’t

C．mustn’t

D．shouldn’t

Answer 1

A

試題分析：考查情態(tài)動詞+have done的用法：can't/ couldn't have done 根本不可能... needn't have done 本沒必要,,,, must have done. 肯定已經(jīng).....(不要用mustn't have done.....) shouldn't have done 本不該......句意：昨天下午我妹妹在大劇院碰見了他，因此他肯定沒有參加你的講座。選A。
點評：Could have done sth本可以做某事；should have done本應該做某事，實際上卻沒有做；must have done一定做了某事。Might have done也許做某事。都是情態(tài)動詞+have done的用法，平時要加強識記憶。
