Question

疑问引导词
哪个正确
what color do you prefer?
which color do you prefer?
where do you live in?
where do you live?
where引导的问句需要介词么
where do you come from?

Answer 1

what color do you prefer?
which color do you prefer?
上两句都对.第一句问的是：你更喜欢什么颜色?（指在所有颜色中做一个选择）,第二句问的是：你更喜欢哪一种颜色?（此时通常是在所提供的选项中做出选择）
where do you live?是正确的,因为where是个副词,所以表示地点的to,in,on,at等必须省略.
where do you come from?这句话是正确的,from不属于上面所提到的介词之列.
