At one with nature PPT,第四部分內(nèi)容:語(yǔ)法精要點(diǎn)撥
“介詞+關(guān)系代詞”引導(dǎo)的定語(yǔ)從句
此類從句是定語(yǔ)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(yǔ)從句中作介詞賓語(yǔ)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(yǔ)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(shuō)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(yǔ)從句中,當(dāng)介詞置于定語(yǔ)從句的謂語(yǔ)動(dòng)詞之后時(shí),可用 that/which(指物); that/who/whom(指人)作介詞的賓語(yǔ),且此處關(guān)系代詞可以省略,特別是在口語(yǔ)中。如:
The man (who/whom/that)you spoke to is a teacher.
你同他說(shuō)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(yǔ)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(yǔ)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(lái)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(yǔ)從句中缺少時(shí)間狀語(yǔ)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(lái)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(lái)這里的那一天。
(2)當(dāng)先行詞表示地點(diǎn),定語(yǔ)從句中缺少地點(diǎn)狀語(yǔ)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(lái)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(yǔ)從句中缺少表示原因狀語(yǔ)時(shí),通常用關(guān)系副詞 why 引導(dǎo),此時(shí)也可以用 for which 來(lái)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(yǔ)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(lái)這所學(xué)校的那一天。
2.二看動(dòng)詞,即根據(jù)定語(yǔ)從句中謂語(yǔ)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(yǔ)從句的意義來(lái)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(méi)有它我看不清楚。
