五、情态动词的解题例析
(1)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。
(2)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。(3)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”。例如:
(NMET2008山东,24)Thank you for all your hard work last week.I don’t think we ______ it without you.A.can manage
B.could have managed C.could manage D.can have managed 根据题干中所给出的时间last week可知我们已经做完了工作,已经完成,故排除A、C两项,再结合could have done表示虚拟语气以及与前面的I don’t think…,故说话者想表达的意思是:离开了你,我们本不可能完成这项工作。故答案为B项。
