come again? 说什么？

在没有听清对方所说的话，或者听到意想不到的话时可以用来反问“说什么？”（What did you say?), “再说一遍呗？”（Can you say that again?)，当然，也可以用(I'm)sorry? Excuse me?

例句：

Good night. Come again.

晚安，再来玩。

Come again? I didn't hear you well.

说什么？我没听清。

I'm sorry? What did you say?

不好意思？能再说一遍吗？

对话：

A: I plan to quit going to university next week.

我下周打算退学。

B: Come again? How will you ever get a good job?

说什么？那你怎么找工作啊？
