what's happening 和 what's wrong的区别

what's happening 和 what's wrong的区别
平时都说他们意思差不多可以互换,但现在在选择题里必须二选一了.
--Come to school in you new school clothes tomorrow?
--Why?__________?空格处这两个选哪个呢?

选what's happening
这是发生什么事怎么了的意思
而what's wrong虽然也有怎么了的意思,但更强调一种错误不和常规事件的发生.比如你同学莫名其妙打了你一拳,你会说what's wrong 而不是另外一个.(这个例子有所冒犯,不好意思)
