单选题 Speaker A: Do you want to come over on Saturday? I'm having a little party.
Speaker B: ______
A. Why are you going to have a party?
B. Oh, I like parties very much. I can meet a lot of interesting people.
C. How about a picnic? I think it is more interesting than a party.
D. Thanks. I'd love to. What time?

【正确答案】 D
【答案解析】[解析] A方向B方发出邀请,需要B方做出接受或谢绝的答复。B项没有作出答复,A和C项与A方的话不相符。D项表示B方欣然接受,是这种场景下的正确用语。
