当陈述部分有情态动词must,问句有4种情况:
(1)mustn't表示“禁止,不可,必须”时,附加问句通常要用must.
You mustn't stop your car here,must you?
你不能把车停在这地方,知道吗?
(2)must表示“有必要”时,附加问句通常要用needn't.
They must finish the work today,needn't they?
他们今天要完成这项工作,是吗?
(3)当must用来表示对现在的情况进行推测时,问句通常要根据must后面的动词采用相应的形式。
He must be good at English,isn't he?
他英语一定学得很好,是吗?
不是, 是mustn't I. 因为是否定回答才用needn't 的
