题目内容
19.---Must I finish the project now?---No,you ______.You _____do it this evening.( )
A. | mustn't; can | B. | needn't; may | C. | can't; must |
分析 --我现在必须完成这项任务吗?
--不,你不必.你可以今晚做.
解答 答案:B.根据No,you,可知这里以Must引导的一般疑问句的否定回答一般用needn't和don'thave to表示.根据No.可知不必现在完成这项任务,可以晚上做. must"必须",语气强;may"可以",语气较弱,这里只是一种建议.故选B.
点评 对待此类考查情态动词的题目,首先要认真审题,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.其次要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.
