关于你用英语怎么说，我的回答是：“What about you?”。

这个短语的来源是英语中的“What about...”一般用来引出一个问题或建议，而“you”则是表示“你”的主格代词。因此，“What about you?”的意思就是“你呢？”或“你怎么样？”

下面是一些例句：

I'm going to the movies tonight. What about you?

I've decided to quit my job. What about you?

I think we should go for a walk. What about you?

I'm feeling really down today. What about you?
