Question

【题目】— Must I wash the clothes now?
— No, you _______. You _______ clean the room first.
A.don't have to； may
B.needn't； need
C.mustn't； may
D.mustn't； must

Answer 1

【答案】A
【解析】句意：—我必须现在洗衣服吗？—不，你不必。你可以先打扫房间。对于Must开头的一般疑问句进行否定回答，常用don't have to或needn't，而不用mustn't。may可以；need，需要，必须；must必须。所以选A。
