定语从句的关于先行词

这就是定语从句。不过是有点特殊。

当先行词有time,day,place,reason,way等的时候，可以用that代替when或where或why或介词+which,

口语中that

还可以省略。

比如：

i

still

remember

the

day

(that)

you

went

away

i

still

remember

the

day

on

which

you

went

away

i

still

remember

the

day

when

you

went

away

i

still

remember

the

place

(that)

you

once

lived

i

still

remember

the

place

in

which

you

once

lived

i

still

remember

the

place

where

you

once

lived

the

reason

(that)

he

was

chosen

remains

unknown

口语中that可以不要

the

reason

for

which

he

was

chosen

remains

unknown

the

reason

why

he

was

chosen

remains

unknown

1，当先行词前有序数词时

2，当先行词前有形容词最高级时

3，当先行词是不定代词或

被不定代词所修饰时

4，先行词是which，为避免重复，也不用which

5, 前面有only时也不用

以上情况才能用it代替。

在这个定语从句中，先行词要用whom，是因为定语从句的先行词要在主句中去找，它在从句中可

以作宾语，主语等成份。whom指代的是主句“The man met the workers”中的“the

workers”，是宾语，所以先行词要用whom。

在这个定语从句中，先行词不能用them。因为定语从句中的先行词只有两类，them不能作先行

词。

1、关系代词： that， which， who， whom， whose。

2、关系副词： when， where， why， how。

扩展资料：

定语从句中的先行词关系代词有主语、宾语、定语之分。要注意区分。

一般who做主语，或其宾格形式的whom做宾语(whom作宾语时可以省略），whose作为定语

（whose不可省略）。关系代词在从句中作主语、宾语、定语等，关系副词在从句中作地点状语

（where），时间状语（when），原因状语（why）。

定语从句放在先行词后面。定语从句分为限定性定语从句和非限定性定语从句。引导定语从句的词有关系代词that、which、who、which、whose和关系副词where 、when,关系代词和关系副词是引导词,在定语从句中担当某一成份。

1、先行词指物时,关系代词用that 或which(在句中作主语或宾语)。

如:China is a country which / that has a large population

The computer game which/ that he is playing is his favorite

2、先行词指人时,关系代词用(who)作主语或宾语,whom (作宾语),whose (作定语),that (作主语或宾语)。如:

The man who is mending the machine has been retired

This is the policeman who/ whom they were talking about yesterday

I like the girl whose mother is an actor

注意:下列情况下关系代词只用that 而不用which 或who。

3、先行词是指物的不代词,如:all, little, few, much, none, anything, nothing, everything等时。如:I didn't understand the words all that he said

4、先行词由最高级、序数词以及any, very, only, all, no, just 等所修饰。如:This is the most beautiful place that I have been to

5、先行词既包括人,也包括物。如:They always like to talk about the man and the things that they see on the road

当主句是以which 或who 开头的特殊疑问句时。如:who is the man that opened up the lab

必须注意的问题

(1)关系词作主语时，从句中谓语的数。

(2)注意区别定语从句与强调句。

①定语从句中关系词作从句成分，复合句。

②强调it无意义，that/who不是引导词。

③强调it is/was和that/who后如果句子意思讲得通则是强调句，讲不通则不是。

It is the museum that/which we visited last year。(定语从句)

It was in the hotel that we stayed last night。(强调句)

(3)定语从句与同位语从句的区别。

①定语从句引导词被称为关系词，that充当主语、宾语、表语。有时可省略。

②同位语从句引导词被叫做连词，that不能充当任何成分，不可省。

Word came that their army was defeated。(同位语)

We expressed to them our wish that was the same as their。(定语)

(4)关系词在从句中省略的情况。

①关系词作宾语，前无介词时。

②关系词作表语。

(5)限制性定语从句与非限制性定语从句的翻译。

(6)关系词前有介词或复杂介词，关系词只能是which和whom。

it作形式主语 代替的是不定式动名词或从句。所以在定语从句中很少有it作形式主语的现象。但从理论上讲 定从中可以有it作形式主语。如

this is the book which it is important for me to have（which代替先行词引导定从并作从句中to have 的宾语。如果改成which is important for me to have则意思不一样。）

这是 我拥有此非常重要 的 那本书。

可以

先行词是定语从句的引导词前面的被定语从句所修饰的名词、代词在定语从句中充当一定的成分我们可以这样认为,之所以称它为先行词,是因为修饰它的定语从句总是放在它之后,先行词总是出现在定语从句之前,而不同于普通形容词修饰名词时,形容词位于名词之前
