At one with nature PPT,第四部分內(nèi)容:語法精要點(diǎn)撥

“介詞+關(guān)系代詞”引導(dǎo)的定語從句

此類從句是定語從句中一種介詞前置句型,介詞與關(guān)系代詞之間存在一種介賓關(guān)系。 當(dāng)關(guān)系代詞在定語從句中作介詞賓語時(shí),把介詞置于關(guān)系代詞前, 即演變出“介詞+關(guān)系代詞”句型。

一、基本構(gòu)成 

1.“介詞+關(guān)系代詞”結(jié)構(gòu)引導(dǎo)的定語從句中,關(guān)系代詞只能用 which(指物)或 whom(指人),即: 介詞+which/whom。 

The man to whom you spoke is a teacher.

你同他說話的那個(gè)人是一位老師。

The city in which she lives is far away.

她居住的城市很遙遠(yuǎn)。

The little girl is reading a book,in which there are many cartoons.

小女孩正在讀一本書,里面有很多卡通圖片。

[名師點(diǎn)津] 

當(dāng)介詞放在關(guān)系代詞的前面時(shí),用在介詞后的關(guān)系代詞不能省略。 

2.在限制性定語從句中,當(dāng)介詞置于定語從句的謂語動(dòng)詞之后時(shí),可用 that/which(指物); that/who/whom(指人)作介詞的賓語,且此處關(guān)系代詞可以省略,特別是在口語中。如: 

The man (who/whom/that)you spoke to is a teacher.

你同他說話的那個(gè)人是一位老師。

The city(which/that)she lives in is far away.

她居住的城市很遙遠(yuǎn)。

[名師點(diǎn)津] 

通常介詞放在定語從句中動(dòng)詞后,也可以放在關(guān)系代詞前面,但有些特殊動(dòng)詞短語搭配不能拆分,介詞只能放在動(dòng)詞后,如:look for, look after, pay attention to,take care of, look forward to,listen to 等。 

This is the pen that/which you are looking for.

這就是你要找的那支筆。

The patient whom she is looking after is her father.

她正照顧著的病人是她父親。

二、關(guān)系副詞 when,where,why 可用“介詞+which”來代替。關(guān)系副詞實(shí)際上是介詞+先行詞。其中 when=表時(shí)間的介詞(如:in,at,during 等)+which;where=表地點(diǎn)的介詞(如:in,at,on,under 等)+which;why=表原因的介詞(如:for)+which 

(1)當(dāng)先行詞表示時(shí)間,定語從句中缺少時(shí)間狀語時(shí),通常用關(guān)系副詞 when 引導(dǎo),此時(shí)也可選用表 示時(shí)間的介詞+which 來代替關(guān)系副詞 when。 

I still remember the day when I came here.( on the day =when) 

我依然記得我來這里的那一天。

(2)當(dāng)先行詞表示地點(diǎn),定語從句中缺少地點(diǎn)狀語時(shí),通常用關(guān)系副詞 where 引導(dǎo),此時(shí)也可選用表 示地點(diǎn)的介詞+which 來代替關(guān)系副詞 where。 

This is the house where I lived last year.( in the house= where) 

這就是我去年住的那所房子。

(3)當(dāng)先行詞為 reason,定語從句中缺少表示原因狀語時(shí),通常用關(guān)系副詞 why 引導(dǎo),此時(shí)也可以用 for which 來代替關(guān)系副詞 why。 

There are many reasons why people like travelling.(for the reasons =why) 

人們喜歡旅游有很多原因。

三、關(guān)系代詞前介詞選擇三原則:一看先行詞,二看動(dòng)詞,三看意義(重中之重) 

1.一看先行詞,即根據(jù)定語從句中介詞與先行詞的搭配關(guān)系選擇。 

I never forget the day on which I came to this school.

我永遠(yuǎn)忘不了我來這所學(xué)校的那一天。

2.二看動(dòng)詞,即根據(jù)定語從句中謂語動(dòng)詞與介詞的搭配關(guān)系選擇。 

This is the iPad on which I spent 3,000 yuan.

這就是我花了三千元買的iPad.

3.三看意義,即根據(jù)定語從句的意義來確定介詞。 

This is my pair of glasses,without which I cannot see clearly.

這就是我的那副眼鏡,沒有它我看不清楚。
