“介词+which/whom”引导的定语从句
关系代词在定语从句中作介词后面的宾语时,有时可把介词提到关系代词的前面，但这时如果先行词是人，要用“介词+whom”引导定语从句;如果先行词是物，要用“介词+which”引导定语从句。且关系代词都不能省略。
Eg:
1. The girl whom I borrowed the bike from is my friend.
2. The girl from whom I borrowed the bike is my friend.
3. How is the film about which I often talked to you?
4. Is this the room in which Mr. Smith lives?
注意：一些固定的含有介词的短语动词在定语从句中不能拆开，即不能把介词放关系词前。
1. This is the bag which he is looking for .
2. The old lady whom she is looking after is her teacher.
