Question

where do you come from? where does you come from? where do you from?

Answer 1

where
does
you
from?where
are
you
come
from?错误
be
from
、come
from
都是“从。。。来，来自。。。”的意思
构成疑问句的时候，be
(is
,are,am)
from
把被be
动词提前，
I
am
from
Hunan.变成疑问句。
Where
are
you
from?
构成疑问句的时候
come
from句中要增加助动词do,does,
did.
例如：They
come
from
Hunan.
Where
do
they
come
from?

Answer 2

do和does是
助动词
，要用来修饰动词的，where
do
they
come
from?这个就对（因为后面是动词come，
does用于
第三人称单数
作主语的句子，而do用于其它主语
表现在时）
are是
系动词
，后面可接名词、形容词、介词等作
表语
，这里where
are
you
from?是对的
错误的句子是where
does
you
from?和where
are
you
come
from?
