Question

对方向你表示谢意时，你应该说：

1. A.
   All right.
2. B.
   That's right.
3. C.
   That's all right.
4. D.
   No, thanks.

Answer 1

C
解析：表示谢意的用语通常为Thank you(very much)．／Thanks a lot．／Thanks(you)for…／It's very kind of you．应答通常为Not at all．／That's OK．／That's all right．／You're welcome．／It's a pleasure.
方法提炼：对容易混淆的用语要记清其基本意义。All right.(可以，行)为答应对方要求的应答语；That's right.(对)为赞成对方观点的应答语。
