题型:不详难度:来源:
--- I did not see your elder brother at the lecture yesterday.
---You ______him, since he went to see Chinese Zodiac---Jackie Chan’s 100th movie.
A.mustn’t have seenB.couldn’t have seen
C.shouldn’t have seenD.needn’t have seen

答案
B
解析

试题分析:句意:--昨天在报告会上我没有看见你的哥哥。--你不可能见他,因为他去看成龙的第100部电影中国的十二生肖。shouldn’t have done过去不应做的而做了;needn’t have done过去没必要做的而做了;couldn’t have done过去不可能做某事。must表推测时不能用在否定句,故选B。
点评:本题的难度适中。情态动词是高中阶段的重难点之一,需要考生熟记它们的用法,在各类考试中经常出现,情态动词的完成式主要用于表示对过去情况进行推测或责备也是高考常考的内容。这里考生容易误选C。
即学即练:—I heard the phone ringing in the office next door.
—You ________ it. They haven’t got a phone yet.
A.couldn’t hear        B.couldn’t have heard
C.didn’t hear           D.wouldn’t have heard
解析:B。句意:由句意可知此处是对过去的事情表示推测,那么否定句用“can/could not+完成时”,故选B。
