题目内容

----No，you _________．You can do it after school．

A．

can't

B．

mustn't

C．

needn't

D．

shouldn't

分析句意：--我现在必须打扫完教室吗，格林老师？
--不，你不必．你可以放学以后打扫．

解答答案：C．根据No，you 可知在这里是作出否定回答．must的含义是必须一定，其否定形式mustn't表示禁止的含义．以must的否定回答一般借助于needn'和don't have to来构成．故选C．

点评本题考查了情态动词的用法．解答本题时注意must的否定形式是常考内容之一，结构比较固定，熟记即可
