總結：關系代詞在從句中作賓語時，介詞可提至關系代詞前，構成“介詞＋which/whom從句”結構。注意：
（1）介詞提前時，關系代詞不可省略；
（2）介詞提前時，只能用“介詞+which”（指事物）以及“介詞+whom”（指人）結構，此時不能用that或who。
（3）當關系代詞作look after, look for, take care of等不能拆開使用的短語動詞的賓語時，介詞不能提前。
eg. 這是我們進行了很多討論的問題。
This is the question about which we’ve had so much discussion.
我跟他說話的那個人是個老師。
The man to whom I spoke is a teacher.
關系代詞前介詞的確定
1. 動詞與介詞的搭配
e.g. The city ________ which I live is a beautiful one.
2. 形容詞與介詞的固定搭配
e.g. You’d better not bring your child to see the animals ______ which he is afraid.
3. 先行詞與介詞的搭配習慣
e.g. 1949 was the year_________ which the P.R.C. was founded.
KEY: in, of, in
［典型例題］
1. The sun gives us heat and light, ________ we can’t live.
答案：without which We can’t live without the heat and the light. 意為我們離開了光和熱就不能生存。指物用which
2. The student ________ we were talking just now is the best student in our class.
答案：about whom talk about sb談論某人，指人用whom
3. I’ll never forget the day _____ she said goodbye to me.
答案：on which She said goodbye to me on the day. 指物用which
4. Who can give me the reason ______ he hasn’t turned up yet?
答案：for which reason固定與介詞for搭配。指物用which
5. Is that the newspaper __________you often write articles?
答案：for which write articles for the newspaper意為為報刊寫文章。指物用which
6. Can you explain to me how to use these idioms______________ I’m not sure.
答案：about which I’m not sure about the idioms. 意為不確定的習語。指物用which
（三）關系副詞when, where, why的用法
1. Great changes are taking place in the city in which they live.
Great changes are taking place in the city where they live.
2. 1949 was the year in which the P.R.C. was founded.
1949 was the year when the P.R.C. was founded.
3. Who can give me the reason for which he hasn’t turned up yet?
Who can give me the reason why he hasn’t turned up yet?
關系副詞都等于一個適當的介詞＋which，在從句中作狀語
1. when在定語從句中作時間狀語，相當于“介詞+ 關系代詞（which）”。
I’ll never forget the day when I joined the league.= I’ll never forget the day on which I joined the league.2. where在定語從句中作地點狀語，相當于“介詞+ 關系代詞（which）”。
This is the house where I lived two years ago.
= This is the house in which I lived two years ago.3. why在定語從句中作原因狀語，相當于“介詞for+ 關系代詞（which）”。
Do you know the reason why she was late?= Do you know the reason for which she was late.
when=in/at/on/…+which;
where=in/at/on/…+which;
why=for /…+which
注：區分關系副詞與關系代詞的區別。只要在定語從句中擔任狀語的，就是關系副詞。
你還記得我們一起去參觀博物館的那一天嗎？
Do you still remember the day when (on which) we went to visit the museum together?
這是我父親曾經工作過的工廠。
This is the factory where (in which) my father once worked.
這就是他憤怒的理由。
This is the reason why (for which) he was angry.
關系副詞引導的定語從句
作用：
1、在定語從句中替代先行詞。
2、在從句中擔任狀語成分，起副詞和介詞短語的作用。
3、起連接作用，把兩個句子連接成為一個帶有定語從句的主從復合句。
關系詞
關系代詞 Who 人 主/賓
Whom 人 賓
Which 物 主/賓
That 人或物 主/賓/表
關系副詞 Whose 人或物 定語
Where 地點
狀語
When 時間
Why 原因
【典型例題】
1、The continent _____ I visited last year was not the one ____ I once worked.
A. which; where B. which; which
C. where; which D. where; where
答案：A這里有兩個定語從句，第一個是_______ I visited last year，先行詞為continent,這里缺少關系詞，關系詞在從句中做賓語，所以用which；第二個定語從句是_______ I once worked，這里的關系詞在從句中做狀語而不是賓語，因為我們不能說I worked the one(the continent)，所以用where。所以選A。
