试题分析:考查情态动词表示推测。如果是对现在情况的推测,要使用“情态动词+动词原形”;如果是对过去情况的推测,要使用“情态动词+have done”;句意:你不可能饿的,两个小时前你刚刚吃过。使用can’t表示有把握的否定推测。故A正确。
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”。
