His failure suggested that he the teacher’s suggestions．

A．can’t have followed	B．needn’t follow
C．mustn’t have followed	D．shouldn’t follow

答案

解析

试题分析：句意：他的失败表明了他不可能听了老师的建议。can’t have done不可能做了某事；must表推测不能用于否定句；因为现在已经失败，所以这是对过去的推测，过去没有听从老师的建议。故选A。
点评：本题难度适中。情态动词的完成式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，它主要用于表示对过去情况进行推测或责备等。
即学即练：—Can I have something to eat, Mum? I feel hungry.
You ________ be hungry. You’ve just had some bread and hamburger.
A. mayn’t B. won’t C. mustn’t D. can’t
解析：D。否定意义的推测用can或者could来代替must,表示强烈语气。
