—Mr. Wang, must I come again to clean the window on Sunday morning?
—No, you _____ . I have asked others to do it.
A.don’t have toB.mustn’tC.can’tD.shouldn’t

答案
A
解析

试题分析:must的含义是必须一定,其否定形式mustn’t表示禁止的含义。故must的否定回答一般借助于needn’和don’t have to来构成,句意:王先生,在星期日早晨,我必须再来打扫窗户吗?——不,你不必。我已经让别人做了。结合语境可知选A。
点评:must的否定形式是常考内容之一,结构比较固定,熟记即可。
