定语从句精讲精练(一)关系代词的选用1.首先找准先行词,并弄清先行词是人还是物。

2.必须弄清先行词在从句中所作的成分,这是选择关系代词的关键。

⑴先行词指人,并在从句中作主语、宾语,关系代词用who/that; as;⑵先行词指物,并在从句中作主语、宾语,关系代词用that/which/as;⑶先行词指人、指物、并在从句中作表语,关系代词用that/as/who/which;⑷先行词指句子,并在从句中作主语、宾语、表语,关系代词用which,as;⑸先行词是“时间名词”,如在从句中作主语、宾语,关系代词用which/that/as; 作状语,用when;⑹先行词是“地点名词”,如在从句中作主语、宾语,关系代词用which/that/as; 作状语,用where;⑺先行词是reason ,如在从句中作主语、宾语,关系代词用which/that/as; 作状语,用why;⑻先行词指人、物,并在从句中作定语,用whose,指物时,可与 the+名词+of which互换;⑼先行词是way,manner等词,关系代词用that,in which,亦可省略;⑽关系代词前有介词时,关系代词用which(指物),who(指人)。

3.选择关系代词时应注意的几点:⑴that 不能放在介词之后作宾语, which,who则可以,如介词在句子后面时,也可用that,也可省略。

This is the room in which we lived last year.=This is the room we lived in last year.这是我们去年住过的房间。

⑵that不能引导非限定性定语从句,其它关系词可以,引导非限定性定语从句的关系代词不可省略。

We walked down the village street,where they were having market day.我们沿着村子的大街走去,村民们正在那里赶集。

⑶as 引导定语从句,主句中的先行词常被such,the same或 so 修饰。

the same...as 指“相类似的人(物)”,而 the same... that 指“同一人(物)。

We will give you such information as will help you in your work.我们将向你们提供有助于你们工作的资料。

This is the same bag as I lost yesterday.这个包和我昨天丢失的那个一样。

(相似性)This is the same bag that I lost yesterday.这是我昨天丢失的那个包。

4.that,which,who 关系代词的用法区别⑴当先行词包含有指人和指物的名词及其短语时,只能用that,不能用who。

如:The heroes and their deeds that he describes in his novels are familiar to us.他在小说里描写的主人公和他们的事绩是我们所熟悉的。

⑵当先行词被any,every,only,very,all,no等修饰时,通常用 that,一般不用 who或 which。

如:He is the only one here that knows English.他是这儿唯一懂英语的人。

There is no difficulty that we can t overcome.没有我们克服不了的困难。

⑶当先行词是序数词或最高级形容词或被这些词修饰时,用 that,一般不用which,指人可以用who。

The first text that we are to learn is very difficult.我们要学的第一篇课文很难。

This is the best movie that I have seen this year.这是今年我看过的最好的一部电影。

⑷先行词是指物的不定代词all,little,few,much,none时,通常用that,一般不用which。

All that glitters is not gold.闪光的不都是金子。

⑸当先行词是指人的不定代词 one 或those和 all 时,通常用who不用that。

⑹当先行词是复合不定代词anything,everything,nothing时,通常用that,something后可以用which。

Have you got everything that you need? 你需要的所有东西都有了吗?⑺当先行词是复合不定代词 everybody,somebody,anyone,no one 通常用who,whom,一般不用that。

Let's go to somebody who was present at the meeting.我们去找出席会议的人。

⑻当先行词是疑问代词who,which时,通常不能再用who/which,而用that。

Who that have worked with him do not like him. 和他一起工作的人谁也不喜欢他。

5.as和which引导的非限制性定语从句⑴as和which引导的非限制性定语从句中作主语代表前面整个句子。

He married her,as/which was natural.他和她结婚是自然而然的事。

⑵as和which 引导非限制性定语从句时,间或的也可以代表前面主句中的补语部分。

He seemed a foreigner,as/which in fact he was.他好像是一个外国人,事实上他就是。

⑶as 引导的非限制性定语从句可以前置,而which引导的非限制性定语从句不可前置。

⑷当从句的谓语是否定形式,或从句谓语带有复合宾语时,用which而不用as。

The ships were frozen in,which not frequently happens in those regions.在那一带水域轮船被冰冻住的事并不经常发生。

He admires everyone in the class,which I find quite strange.他羡慕班上的每个人,这我认为太奇怪了。

6.限制性定语从句和非限制性定语从句⑴限制性定语从句修饰先行词,若省去,则意义不完整,影响表达,常含有先行词所表达意义中的一部分。

非限制性定语从句修饰先行词,可省去,意义不受影响。

常含有对先行词解释的意味。

He has a sister,who teaches English in a middle school.他有一个妹妹在中学教英语。

(只此一个妹妹)He has a sister who teaches English in a middle school.他有一个在中学教英语的妹妹。

(还有其它姊妹)⑵限制性定语从句修饰先行词,而非限制性定语从句修饰整个句子。

He wears a red shirt,which makes him like a girl.他穿了件红衬衣,使他像女孩。

(说明全句)He wears a red shirt which makes him like a girl.他穿了件使他与女孩相像的红衬衣。

(修饰名词)⑶如先行词是专有名词,只能是非限制性定语从句。

7.介词加关系代词中介词的选用⑴根据先行词的习惯搭配。

如:I was surprised at the way in which he treated the old man.他对待老人的方式使我吃惊。

There is a tall tree outside,under which stands our teacher.外面有棵大树,我们老师就站在下面。

8.使用定语从句应注意的问题⑴关系代词在从句中作主语时,从句的谓语动词应根据先行词来决定。

The students who are in Grade Three are going to climb the hill tomorrow.三年级学生明天去爬山。

⑵定语从句有时不直接放在先行词之后,而是在中间插入一个定语、状语或谓语。
