My sister met him at the street yesterday afternoon, so he __________ your lecture. A．shouldn’t have attended B．couldn’t have attended C．mustn’t have attended D．needn’t have attended

Answer 1

B

试题分析：考查情态动词用法。Shouldn’t have done本不应该做某事，实际上却做了（虚拟语气）；couldn’t have done不可能做某事（对过去情况的推测）；needn’t have done本不需要做某事，实际上却做了（虚拟语气）；句意：我的姐姐昨天下午在街上遇见了他，所以他不可能去听了你的演讲。故B正确。 点评：考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。
