改定语从句

You are looking for the girl who is waiting at the school gate.
who引导的定语从句用来修饰the girl

The girl who you are looking for is waiting at the school gate.
由两句话改为一句话的定语从句，首先要决定谁做谁的定语。两句话中都有gril，1.女孩正等在校门口。2.你正找那个女孩。显而易见，“你要找的女孩正等在校门口。”

你正在找的girl在校门口等人呢。

The girl which you are looking for is waiting at the school gate.

The girl is waiting at the school gate who you are looking for the girl

The girl who you are looking for is waiting at the school gate.
