问题补充：

—How much should I pay for the dinner?

—.

A. You are welcome

B. Thats my pleasure

C. Its my treat

D. Its my charge

答案：

A. You are welcome

B. Thats my pleasure

(答案→)C. Its my treat

D. Its my charge

解析：选C考查交际用语。句意：“这顿饭我该付多少钱？”“我请客。”You are welcome“不客气”；Thats my pleasure“非常高兴为你服务”； Its my treat “我请客”；Its my charge没有这个用法。故选C。
