什么时候用what is wrong with you 什么时候用what was wrong with you

比如你和一个朋友在街上碰见的时候，朋友见你一脸病容，就问：
What's wrong with you? 你怎么了？
指的是现在、目前这段时间的状态。

如果头一天你和朋友匆匆见了一面但他没机会问，今天又碰见了，他看你脸色比昨天好多了，就问：
what was wrong with you? 你（昨天）怎么了？
指的是过去的状态。

前者是现在的时候，后者就是过去了

你怎么了??

is是现在出了状况,问对方发生什么事情..
was是过去..现在已经没有事了..

发生在现在用is 发生在过去用was

what was wrong with you中was一般用于过去进行时中。
what is wrong with you中is是be动词。一般疑问句。陈述句都会用到

Is or Was?

What is wrong with you?
It is what we all see.
I just hope you get better,
You aren't what you used to be.

What was wrong with you?
It has been for so long.
How come you are not what you are?
Something must have been wrong!

Good luck.
