帶介詞的定語從句

　　引導定語從句的關系代詞可以作介詞的賓語，形成帶介詞的定語從句。這種結構有兩種：

　　從句由“介詞+which”(表示事和物)

　　從句由“介詞+which”(表示人)

　　e.g----The man to/with whom he is talking is a teacher.

　　----The school in/at which I am studying is a key school.

　　解題要訣：

　　掌握常用介詞的基本用法

　　掌握常用動詞，形容詞與介詞之間的固定搭配

　　非限定性定語從句

　　1.當指物時，不能用that只能用which

　　2.which有時用來指整個句子或句子的一部分。

　　e.g. He died suddenly, which made her very sad.

　　he said last night he went to sleep with his clothes on, which was very uncomfortable.

　　關系詞的使用一看先行詞，二看關系詞在從句中的作用，在此基礎上熟記幾個常用的固定句式，如：the same … as , such … as…

　　The film is the same as we have expected.

　　關系詞在句中做定語 – whose

　　應該熟悉關系詞做定語時的各種變體。

　　the office whose windows are broken

　　the office the windows of which are broken

　　“介詞 + which/whom”的結構做關系詞

　　A. 介詞是句中短語搭配的一部分 ,如pay attention to, take care of 等固定短語動詞，在定語從句中一般不宜將介詞與動詞分開。

　　This is the boy whom she has taken care of.

　　B. “部分 + of + 整體名詞”的結構，該結構做關系詞也就是 “部分名詞 + of which/whom”的結構。

　　Her two brothers, both of whom work in Scotland, ring her up every week.

　　We will have a party in the room, the window of which has been broken.

　　C. 另一種介詞是表示范圍的介詞

　　He has composed many pieces of music popular with young people, ____ which this is an example.

　　of

　　D. 有時介詞與先行詞構成短語

　　It is useful to be able to predict the extent ____ which a price change will affect supply and demand.

　　A. from B. with C. to D. for

　　C. to
