what don't you like和 what you don't like哪个表达是对的

应该说两个表达都是对的，只是看你怎么用。

反问句时，用“What don't you like?”
从句时，用“..what you don't like..”。
例如：
主语从句 What you don't like is not a secret.
宾语从句 I know what you don't like.

--------------------------------------------
“你不喜欢什么？”
What do you dislike?

what you don't like

what don't you like
因为这是一个疑问句．所以要用疑问句的语序
what+助动词＋主语＋动词原型．．．？

what don't you like
疑问句助词提前.

应该是what don't you like？
what+助动词＋主语＋动词原型 的形式

按英美的习惯应该说成是
what's your dislike.
