Nina wants to know _.
A where does Mike live
B where does Mike live in
C where Mike lives
D where Mike live
选C.Where does.是问句.题目这里是从句.所以在CD找.Mike是第三人称,所以live要加s.什么是从句？= =啊。。。从句时用来修饰，解释，限定句子中某些成分的。比如说Mike is a boy who likes cars.那么who likes cars就是修饰boy。Mike是一个boy，一个有什么特点的boy? 是一个like cars喜欢车的boy。就是这样。。
