---Must I finish the work now ?
---No,you needn't. You can do it tomorrow.
--- May I go swimming now?
--- No, you mustn't. You must finish your homework first.
needn't因为must的否定形式是needn't,所以答案不可能是A或B。
AB都不对,正确的答案应该是needn't
中文翻译如下:
我必须现在完成我的工作吗?
不,你不必现在完成,明天再做也可以.
不可能是A或B
答案肯定错了
Must I .....?
no,you needn't./you don't have to.
yes,you must.
这是100% 对的。
