1. 定语从句的概念和特点
定语从句在复合句中起定语作用,修饰主句中的名词或代词。被定语从句所修饰的词叫先行词。定语从句一般在先行词之后。引导定语从句的词叫关系词。关系词在先行词与定语从句之间起纽带作用。关系词代表着先行词并在定语从句中充当一个句子成分。如:
A man who
sells books in a shop is
called a
bookseller. 开店售书的人叫做书商。(who
sells books为定语从句,修饰先行词a man)
The
discussion was on the
election which had
taken place the day
before. 讨论的内容全是有关前一天选举的事。(
which had
taken place the day
before为定语从句,修饰先行词the
election)
2. 关系代词和关系副词的用法
根据关系词在定语从句中的不同用法,可分为关系代词和关系副词。关系代词主要有who, whom,
which, that,
whose等,在定语从句中作主语、宾语、定语等;关系副词主要有when,
where, why等,在定语从句中作状语。具体用法如下:
(1)关系代词的用法:当先行词指人时,若它在从句中作主语,则用who;若它在从句作宾语,则用whom或who;若它在从句中作定语,则用
whose。如:
The man who told me this
refused to tell me his name. 告诉我这事的人不肯告诉我他的名字。
The
woman whose umbrella you took is very
angry about it. 你拿了那个女人的伞,她非常生气。
当先行词指物时,若在定语从句中作主语或宾语,则用
which;若它在定语从句中作定语用,则用of
which或whose。如:
I saw
something in the
paper which might interest you. 我在报上看到一样可能使你感兴趣的东西。
He’s
written a book the name of
which (
whose name) I’ve
forgotten. 他写了一本书,书名我给忘了。
(2) 关系副词的用法:关系副词主要有when,
where, why等,在定语从句中作状语,分别表示时间、在点和原因。when主要放在time, day,
years,
season, age,
occasion等时间的名词后;where主要放在
place, city, town,
village,
house等地点名词后;why则通常只放在
reason后。如:
Wednesday is the day when the
shops are not open in the
afternoon. 星期三下午商店不开门。
Give me one
reason why we
should help you. 给我举出一个我们应当帮助你的理由。
要特别注意,
activity, case,
point, even,
situation, job,
organization,
position等抽象名词后接
where引导定语从句的用法(这是近几年高考的一个新热点)。如:
I don’t want a job
where I’m
chained to a desk all day. 我不想找一份整天坐办公桌前的工作。
Today, we’ll
discuss a
number of
cases where beginners of
English fail to use the
language properly. 今天,我们将讨论一些英语初学者对英语使用不当的问题。
The
treatment will
continue until the
patient reaches the
point where he can walk
correctly and
safely. 治疗将会持续到病人可以正常且安全地行走。
If you risk
something important, you
cause it to be in a
dangerous situation where you
might lose it. 你如果拿重要的东西去冒险,那你就是将它置于一种可能会失去它的危险境地。
