单项选择题
Speaker A: Thank you for everything you've done for me during my stay here. Speaker B:______
A．Oh, this is what I should do.
B．You are welcome.
C．Don't say that. Actually I have done little for you.
D．I'm sorry for not having looked after you well.
答案
参考答案：B
解析：A方感谢B方为他们所做的一切，B方只需回答“不客气”就可以。四个选项中，只有B项“You are welcome'’表示这一意思，是正确答案。A、C和D项都是汉语式的表达习惯，不符合英语的交际习惯。
