单选题 A: Why don't you have dinner with me tonight?
B: ______

A. Because I have an appointment.
B. Sorry about that, but I have to go to a party.
C. The reason is that I have to work overtime tonight.
D. I'd love to. but I have to finish my paper.

【正确答案】 D

【答案解析】[解析] “Why don't you have dinner with me tonight?”是邀请而非责问。因为用的是现在时，且时间状语为“tonight”，事情尚未发生。A和C选项都是给出了一个理由，一个解释，但我们知道A的问话并非责问。B和D都是谢绝邀请。根据英文习惯，谢绝邀请的说法应该是“I'd love to, but...”。
