Question

【題目】— 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：—我必須現(xiàn)在洗衣服嗎？—不，你不必。你可以先打掃房間。對(duì)于Must開頭的一般疑問句進(jìn)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，必須；must必須。所以選A。
