为什么where do you come不对where不是等于介词+sp吗,应该就相当于取代了from啊.实在搞不懂.而where do you live就是对的.why?

where do you come from?where do you come foom? Where do you come ___? Where do you come form? Do you know No,Idon'know A.where he's from B.where is he come C.where does he come fron D where come he from为什么 where do you come from?回答是什么 where do you come from句子成分分析, Where do you come为什么还得再末尾加个from?where不能做come的状语? where do you come fromfrom是不是come 的宾语 where are you come from?where are you from?和where do you come from? 都是对的.但是 where are you come from ? 就不对,谁知道是为什么? 你从哪里来除了问Where do you come from?还可以怎么问Where are you from 为什么不能像Where do you come from?一样用COME Where are you from 为什么用are,where do you come from又为什么用DO了能在举一些类似的句型吗? where did you come from和where do you come from有什么区别? where are you come from 还是where do you come form? Where you coming from和where did you come from,还有where do you come from 我有点搞不清楚 where are you come from跟where do you comefrom有什么区别where are you come from?where are you from?where do you come from?where do you from? where do you come from 中为什么加了from 而where do you live?中把in 省略了呢?他们都是不及物动词啊 where do you live为什么用do 为什么是Where does your pen pal come from,而不是Where do your pen pal come from?you 不是第二人称吗?为什么用does?
