帶介詞的定語(yǔ)從句

　　引導(dǎo)定語(yǔ)從句的關(guān)系代詞可以作介詞的賓語(yǔ)，形成帶介詞的定語(yǔ)從句。這種結(jié)構(gòu)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(dòng)詞，形容詞與介詞之間的固定搭配

　　非限定性定語(yǔ)從句

　　1.當(dāng)指物時(shí)，不能用that只能用which

　　2.which有時(shí)用來(lái)指整個(gè)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(guān)系詞的使用一看先行詞，二看關(guān)系詞在從句中的作用，在此基礎(chǔ)上熟記幾個(gè)常用的固定句式，如：the same … as , such … as…

　　The film is the same as we have expected.

　　關(guān)系詞在句中做定語(yǔ) – whose

　　應(yīng)該熟悉關(guān)系詞做定語(yǔ)時(shí)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(jié)構(gòu)做關(guān)系詞

　　A. 介詞是句中短語(yǔ)搭配的一部分 ,如pay attention to, take care of 等固定短語(yǔ)動(dòng)詞，在定語(yǔ)從句中一般不宜將介詞與動(dòng)詞分開(kāi)。

　　This is the boy whom she has taken care of.

　　B. “部分 + of + 整體名詞”的結(jié)構(gòu)，該結(jié)構(gòu)做關(guān)系詞也就是 “部分名詞 + of which/whom”的結(jié)構(gòu)。

　　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(shí)介詞與先行詞構(gòu)成短語(yǔ)

　　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
