询问你从哪里来正确的说法where do you from?那可以说成是where are you from吗 如果不可以的话是为什么？

where are you from?才是正确的说法.
be from

正确的是where are you from?或是where do you come from?

where are you from?

或是where do you come from?

因为from是介词。

where are you from? 没有动词，所以必须有be动词are

where do you come from？come是动词，用助动词do提问

where are you from? where do you come from?

这两个都是正确的。你说的第一句是并句
