Question

what are you ?和what do you are ?的区别是什么？

Answer 1

单纯what are you?和what do you do?是没区别的，都是询问对方是做什么工作的。

what are you do 这个句子的错误在于，没有区分助动词和行为动词的使用问题
具体如下：
be动词里面，在现在时的情况下，分为am ,is ,are ；过去时则为was ,were
那么其后面，通常是
1）表语成分（形容词，nice ,big 或者介词 in the room ,等）
2)可以是非谓语形式，如分次，不定式，动名词等（His job is washing cars --动名词）
3）名词性从句(如表语从句 His dream is that he would like to have his own lab .
本题这个句子，可以修改为“what are you doing ? 或者what do you do ?

追问

“what are you do”？谢谢，我问的是“what do you are ”（其实也是个错句）

Answer 2

What are you? = Waht do you do? = What's your job? 意思是“你做什么工作的？”
What do you are? 语法是错误的，正确的可能是 What do you do?，意思和上句一样，提问工作。

Answer 3

What are you?　你是做什么的？是问别人职业。
What do you are?　是错误的，应该是What do you do? 你做什么的？也是问职业的。
