定语从句的关系代词
引导定语从句的关系词有关系代词和关系副词,而定语从句的关系代词又有什么呢?
引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who(宾格whom,所有格whose),as等;关系副词包括where, when, why等。关系代词和关系副词放在先行词及定语从句之间起连接作用。关系词起3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。
1. who指人,在从句中做主语
The boys who are playing football are from Class One.
Yesterday I helped an old man who lost his way.
2. whom指人,在定语从句中充当宾语,常可省略
Mr. Liu is the person (whom) you talked about on the bus.
Mr. Ling is just the boy whom I want to see.
注意:关系代词whom在口语和非正式语体中有的时候常用who代替,并且可以省略。如:
The man who/whom you met just now is my friend.
3. whose通常指人,也可指物,在定语从句中做定语
He has a friend whose father is a doctor.
I once lived in a house whose roof has fallen in.
whose指物时,常用以下结构来代替:
The classroom whose door is broken will soon be repaired.
→ The classroom the door of which is broken will soon be repaired.
Do you like the book whose cover is yellow?
→ Do you like the book the color of which is yellow?
4. which指物,在定语从句中做主语或者宾语,做宾语时可省略
Football is a game which is liked by most boys.
This is the pen (which) he bought yesterday.
5. that指人时,相当于who或者whom;指物时,相当于which。在定语从
句中做主语或者宾语,做宾语时可省略
The number of the people that/who visit the city each year rises one million.
Where is the man that/whom I saw this morning?
The number of people who/that lost homes reached 250,000.
It sounded like a train which/that was going under the house.
The boy(whom/that/who)we saw yesterday was John’s brother.
The car(which/that)my uncle just bought was destroyed in the earthquake.
关系代词代替先行词在定语从句中充当主语、宾语、定语,因此定语从句不能再出现关系代词所替代的名词或代词。如:
(误)The story(that/which)you told me it yesterday is interesting.
(正)The story(that/which)you told me yesterday is interesting.
昨天你给我讲的`那个故事很有趣。
That 和which在定语从句中指物时,常常可以互换。但下面几种特殊情况,不能互换,只能用that, 不用which.
1)先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which. 例如:
He was the first person that passed the exam.
他是第一个通过考试的人。
2)被修饰的先行词为all, any, much, many, everything, anything, none, the one等不定代词时,只能用that,而不用which. 例如:
Is there anything that you want to buy in the shop?
你在商店里有什么东西要买吗?
3)先行词被the only, the very, the same, the last, little, few 等词修饰时,只能用that,而不用which. 例如:
This is the same bike that I lost.
这就是我丢的那辆自行车。
4)先行词里同时含有人或物时,只能用that, 而不用which.例如:
I can remember well the persons and some pictures that I saw in the room.
我能清楚记得我在那个房间所见到的人和一些照片。
5)以who或which引导的特殊疑问句,为避免重复,只能用that. 例如:
Who is the girl that is crying?
正在哭泣的那个女孩是谁?
6)主句是there be 结构,修饰主语的定语从句用that,而不用which.例如:
There is a book on the desk that belongs to Tom.
桌子上那本书是汤姆的。
