试题分析:考查情态动词+have done的用法:A.shouldn"t have done本该做…而没有B.couldn"t   have done过去不可能做了,C.needn"t  have done 本不必做…而做了,D.mustn"t和完成式连用只能用于肯定句,句意:--玛丽和我分手了!--你本不该忘记情人节。选A。
点评:情态动词表推测注意以下解题步骤:认真审题,结合所给出的语境,正确把握说话者的语气、情感、态度、观点等。认真思考所给选项中情态动词的基本特征和用法,并结合语境推敲答案。要注意把握时间概念。情态动词无论是表达“推测和可能性”,还是表达“虚拟”这一概念,只要是对过去已经发生的事情进行描述,一律用“情态动词+have done”这一结构;对现在或将来的事情进行描述,用“情态动词+动词或系动词原形”。
