例， Must I finish my homework right now?
No,you needn".
2.must做推测用时可翻译为“一定”，这种情况下没有疑问句，也没有否定句。其否定形式用can"t.翻译成“不可能”。
例，WangLin must be in the next room.I saw him there just now.王林一定在隔壁，我刚才在那见他啦。
WangLin can"t be in the next room.He is ill in hospital.王林不可能在隔壁，他生病住院呢。
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.
For example:
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）
must的否定形式就是needn`t.
needn`t是不必
mustn't是禁止,不允许
mustn't只是用作禁止的时候用。
