试题分析:考查情态动词用法。“情态动词+have done”既可以表示对过去情况的推测,也可以表示对过去情况的虚拟。Shouldn’t have done本不应该做某事,实际上却做了;can’t have done不可能做了某事;wouldn’t have done不会做了某事;句意:—你知道David到哪里去了?我到处都找不到他。—我不可能走远,他的眼镜还在这里。根据句意是对过去发生的事情的有把握的否定推测,故使用can’t have done;故C正确。 点评:本题是高考必考考点,一定要牢记句型意思。must have done过去肯定做了某事。should have done 本应该做而实际未做。 can’t have done 过去不可能做了某事;shouldn’t have done 本不应该做而实际做了。 need have done 本有必要做某事;needn’t have done 本没有必要做某事;注意没有 mustn’t have done的形式。 |
