– Must I get to school at 7:30 every morning?
– . Just arrive before 8 o’clock.
A. No, you needn’t
B. No, you mustn’t
C. No, you can’t
D. No, you don’t

(答案→)A. No, you needn’t B. No, you mustn’tC. No, you can’tD. No, you don’t解析：句意：我必须每天早晨在7:30到校吗？不，不需要。八点前到就可以。由must引导的疑问句其肯定回答用must，否定回答用need；mustn’t意为“绝不，坚决不能”；故选A。

我明天再问问老师，叫他解释下这个问题
