我必须乘公交车到火车站吗?不用.你可以乘地铁.
用must来问的句子,如果是否定回答,要用needn't表示“没必要”.
B.can't表示“不能够”,C.mustn't表示“禁止”,D.shouldn't表示“不应该”,意思都不合适.

选A。问句“我必须……?”肯定回答“是的,你必须”否定“不,没必要”
mustn't表示“禁止”的意思,如:The kids mustn't play on the street。所以C选项放在这里不合适。

A

答:不,你可以不乘公共汽车,你可以乘地铁。
Needn't的意思是不必须,而Mustn't的意思是禁止,不能用。回答Must起头的句子,Yes you must.或者No you needn't.
