---Molly：Oh, ______, but I have an appointment with the doctor. Thank you for inviting me.

---Polly：That's, OK. ______.

1. A.
   I'd really love to; I have a meeting

3. C.
   that sounds good; Perhaps some other day
4. D.

Answer 1

D
思路分析：本题是关于邀请和应答的交际用语．对邀请不能接受，最好回答“I'd love to, but…”．在but后说明你不能接受邀请的原因；第二空应填和商定come over for lunch时间相关的词语．
