who is you？

1.如果在一张有许多人的照片里问哪个是你，一般说Which one is you?不大会 说Who is you?;
2.y如果大写，那么You是个人名，是在问“You是谁？”
3.这个"你"指的是谁?
比如有一个人老是在说you怎样you怎样,听的人又不止一个,你想弄清究竟在对谁说,你就可以问他"(你说的这个)你指的是谁?":
who is YOU (that you are talking to) ?

错的吧
应该是who are you
you后面的be动词只能是are

翻译过来就是 谁 是 你

你是谁

who are you

---The first one from the left in the picture is you.
---What do you mean? Who is you?
