must 的句子的肯定回答与否定回答.

肯定: Yes, you must!
否定: No, you needn't
不能用mustn't 因为它的意思是“禁止” 而它的否定是“不需要”的意思

Yes,you must.
No,you mustn't

考虑语气及语意

肯定: must
否定: needn't.

must
needn\'t

Must I finish this tonight?
肯定: Yes, you must!
否定: No, you needn't.

肯定回答都是Yes,you must.但是否定回答可能是No,you needn't.也可能是No,you mustn't.要根据语境……举个例子吧……
Must I go now?(我现在一定要走吗?)
Yes,you must.(是的,你一定要走)
No,you needn't.(不,你不需要走.意思是你可以不走)
No,you mustn't.(不,你不许走.意思是你一定要留下)
