-Must I finish the report today?

-_____________________. You can finish it tomorrow.

选择一项：
A. Yes, you must
B. No, you mustn.t.
C. No, you don.t have to

答案：C 解析：本题考核“征求意见”的交际用语。对于“Must I...”问句的回答要视上下文而定。在此句中，回答者后半句说了 “You can finish it tomorrow.”, 这就意味着这份报告不必于今日完成，所以答案为C。 正确答案是：No, you don't have to
