Grammar
The Attributive Clause(prep+which/whom)
由“介詞+which/whom”引導的定語從句
從句
一、基本用法
當關系代詞在定語從句中充當介詞的賓語時，我們可以用“介詞＋關系代詞”引導定語從句。如果先行詞為人時，用“介詞＋whom”；如果先行詞為物時，用“介詞＋which”。who和that不能用于此結構。
My father works in Volkswagen，in which the workers are well paid.
我爸爸在大眾汽車公司工作，那里的員工待遇優厚。
(in which引導非限制性定語從句，which指物)
二、介詞的選擇
1．根據先行詞與介詞的搭配習慣來確定。先行詞往往是表示時間、地點、原因、方式等的詞，它與介詞之間有一定的聯系。
Do you still remember the days during which we worked together?
你還記得我們在一起工作的那些日子嗎？
2．根據定語從句中的謂語動詞或形容詞確定介詞。該動詞或形容詞常與某些介詞構成固定搭配。
The social problem about which the two sides are debating with each other is a very serious one.
(debate with sb.about...就……與某人展開辯論)
雙方正在展開辯論的社會問題是很嚴重的一個。
3．根據句子的意思確定介詞。有些句子，先行詞完全一樣，定語從句中謂語動詞也不是固定的動詞短語。這時，需要根據句子所要表達的意思選用不同的介詞。
This is the book about which you have talked to me.
這是你曾經給我談起的那本書。
This is the book on the cover of which there is a map of China.
這是封面上有張中國地圖的那本書。
三、“介詞＋關系代詞”與關系副詞的替換
在定語從句中若先行詞為時間名詞，地點名詞或reason，“介詞＋關系代詞(which)”可用相關的關系副詞when，where，why等替換
The reason for which (＝ why) he refused the invitation is not clear.
他拒絕邀請的理由還不清楚。
Great changes have taken place in the city in which (＝where) I was born.
我出生的那座城市發生了巨大變化。
