定语从句里面的关系代词的用法

1.常用的关系代词：which, that, who, whom。Whom现在用的很少。前面有介词只能用which，不能用that。

2. 关系代词在考试中的特殊情况。

What:1)它是子母同体。相当于一个关系代词以及一个先行词。What前面不应该在出现先行词。 如果前面已经偶一个关系词，就不能用what来引导。例如：You can have everything what you like. what=all that,所以这儿不能用what.

All---is a continuous supplying of the basic necessities of life

A. what is the need

B. the things need

C. for our needs

D. that is need

2)what单独使用，后面不加名词。

例如：She is not what she used to be.

3)what 后面加名词

例如：What money I have has been given to you.

19xx年考题：______he knows about it is out of date and in accurate

A. What little

B. So much

C. How much

D. So little

as

1. like

2. 作为

3. when

4. 引导定语从句。即可引导限制性定语从句，也可以引导非限制性定语从句。引导限制性定语从句一般式固定用法。如as…as, such…as

as引导非限制性定语从句

例如：I was a boy which you know. which可以用as替换。

As is so often pointed out knowledge is a two edge weapon which can be used equally for good or evil.

as引导限制性定语从句

考试中往往考固定搭配。

例如：Such a student as works hard were be sure to succeed.

than 作为关系代词可以引导定语从句

More families consist of one parent households or two working parents; consequently, children are likely to have less supervision at home ____ was common in the traditional family structure .

A.than B.that C.which D.as

特点：

1) than作为关系代词引导词在从句中一般必须做主语或者作宾语。

2) than 前面的主句必须要有比较级

3) 比较级所修饰的名词就是than指代的对象

关系副词

When引导的定语从句。

1)先行词必须是表示时间的名词。

Or so the thinking has gone since the early 1980s, when juries began holding more companies liable for their customers’ misfortunes.

2)如何区分when引导的定语从句和状语从句。用句子表示状语就是状语从句。例如：When I go to school, I will work hard.

从两方面区分：

When 引导的定语从句前一定有表示时间的名词；When 引导的状语语从句前没有有表示时间的名词。

从翻译的角度看如果是引导的定语从句可以不翻译。如果是状语从句就必须翻译成当……时候。

When=on which

Where

where=in which

where引导的从句先行词必须是表示地点的名词。例如： I was born in Beijing where the Olympic games will be held.

先行词表示地点,不一定用where来引导。例如：

I have never been to Beijing ,but it’s the place __.

A.where I’dlike to visit

B.in which I’d like to visit

C.I most want to visit

D.thar I want to visit it most

 

第二篇：定语从句中介词加关系代词的用法

“介词+关系词”的用法

1、关系代词在从句中作介词的宾语时，介词常可以提前，但介词提前时，关系代词只能用which 或 whom。

如：The school (that/which) he once studied in is very famous.

→The school in which he once studied is very famous.

Tomorrow I will bring here a magazine (that/which) you asked for.

→Tomorrow I will bring here a magazine for which you asked.

We'll go to hear the famous singer (whom/that/who) we have often talked about. →We'll go to hear the famous singer about whom we have often talked.

2、关系副词when, where, why 和介词+which之间的关系。

关系副词when, where, why可以用适当的介词+which来替代。介词的位置非常灵活，有时放在关系代词之前，有时放在动词之后。如：when=in/on/at…+which, where=in/on/at…+which, why=for+which

如：I won’t forget the date when( on which) I was born.

This is the room where (in which) I lived. = This is the room which I lived in.

I don’t know the reason why (for which) he hasn’t come today.

Tom still remembers the days when (in which) they lived in Tianjin.

注意：

1). 含有介词的动词短语一般不拆开使用，如：look for, look after, take care of等

如：This is the watch which/that I am looking for. (√) This is the watch for which I am looking. (F)

2). 若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose

如：The man with whom you talked is my friend. (√) The man who/that you talked with is my friend. (F)

The plane in which we flew to Canada is very comfortable. (√)

The plane in that we flew in to Canada is very comfortable. (F)

3).“介词+关系代词”前可有some, any, none, both, all, neither, most, each, few等代词或者数词 如：He loved his parents deeply, both of whom are very kind to him.

In the basket there are quite many apples, some of which have gone bad.

There are forty students in our class in all, most of whom are from big cities.

4). 把握“介词＋关系代词”结构中介词的选用

介词的选择与主句中先行词的搭配密切相关。

如：That”s the reason for which he was late for school. This is the book on which I spent 8 Yuan.

介词选择的三大规则：

1. 取决于从句中的谓语动词同介词的搭配。（V+ pre.）

如：He is the man whom I talked with this morning.

2. 取决于先行词同介词的常规搭配。

四组常考的搭配：1）extent degree （程度）同 to 搭配

2）price(具体多少钱时与at; 若指价格方面与in 搭配) speed rate 同at搭配

3）field area aspect sphere （领域，方面）同 in 搭配 例句：The field in which I studied in university is psychology.

4) basis ground foundation （基础）同on 搭配
