Hayley教口語，“來來回回”用英語怎么說？

back and forth

來來回回;反復

He walked back and forth in the room, thinking about the problem.

他在屋里來回走動，思考著問題。

Don't say this back and forth, I know how to do.

不要反復說這個，我知道該怎么做。

A:Please don't go back and forth, I'm doing my homework.

請不要來回走動，我在寫作業(yè)。

B:Oh, I'm sorry, I didn't notice that you were doing your homework.

哦，對不起，我沒注意到你在寫作業(yè)。
