高中英语语法专题复习：定语从句

知识要点

1. 关系代词和关系副词的选用

2. 限制性定语从句和非限制性定语从句的区别

3. 几组的关系词特殊用法

一、定义：在复合句中，修饰名词或代词的从句叫做定语从句。

The happy man who lives next to me sells vegetables.

You must do everything that I do.

被定语从句修饰的词，叫先行词。比如上面两句中的 man 和 everything.

引导定语从句的词，叫关系代词和关系副词。比如 who, whom, that, which, wh

ere, when, why 等

关系词三重作用：①连接主从句；②指代先行词；③在定语从句中担任句子成

分。

The man who lives next to me sells vegetables.

该句中，who lives next to me 是定语从句，修饰先行词 the man， “who”是引导定语从句的关系词，代替先行词 the man，在定语从句中作主语。

二、关系词

引导定语从句的关系代词有who, whom, which, that, whose, as 等和关系副词w

here, when, why 等。关系代词和关系副词在定语从句中担任句子成分。 1. 用关系代词 that, which, who, whom 引导的定语从句

who 指人，用作主语

whom 指人，用作宾语

which 指物 ，用作主语、宾语皆可

that 指人和物， 用作主语、宾语皆可

The teacher who visits our school today is from Guangzhou.

Mrs Read is the person whom you should write to.

They planted some trees which didn’t need much

water.

The fish (which) we bought this morning were not fresh.

A plane is a machine that can

fly.

The noodles (that) I cooked were delicious.

2. 用关系代词 whose 引导的定语从句：

先行词既可指人，也可指物，一般译为“谁的”“什么东西的”，请看例子

The room whose window faces south is mine.

3. 用关系副词 when、where、why 引导的定语从句

(1) when 在从句中作时间状语

October lst, 1949 is the day when (=on which) the People’s Republic of Chin

a was founded.

(2) where 在从句中作地点状语

I recently went to the town where (=in which) I was born.

(3) why 在从句中作原因状语

The reason why (=for which) he was late was that he missed the train. 高考试题中对于 where 的考查趋于复杂，从先行词为明显的“地点”转为“地点的模糊化”。事实上，对于 where 这个词，不能只理解为表地点。当先行词为 situa

tion, case, stage, point 等，且关系词在定语从句中作状语时，要用到关系副词

where 引导。 way (方式，方法)后常用 in which 或 that 引导定语从句，也可省略：

They have reached the point where they have to separate with each other.

他们已经到了必须分手的地步了。

Do you know the way (in which/that) he worked out the problem?

三、限制性定语从句和非限制性定语从句的区别相同点：都属于定语从句

不同点：① 形式上：有无逗号。限制性定从无逗号。非限制性定从，有逗号。

② 意义上：限制性定从对先行词起修饰限制作用；非限制性定从起补充说明作用。

He has found the book (that) he was looking for.

Yesterday I met Li Ping, who seemed to be very busy.

He told me a story yesterday，which I think is very interesting. (which 指 a s

tory)

Tom has made great progress, which makes me very happy. (which 指逗号前面整句话意思)

四、几组关系词的特殊用法

1. 限制性定语从句中，用关系代词 that 不能用 which 的情况：

①当先行词是指物的不定代词 all, little, few, much, everything, anything, not hing, none, some

Do you have anything that you want to say for yourself?你有什么要为自己要说的吗？

②当先行词前面有 the only, the very(恰恰，正好),any, every, some, no, all, f

ew, little, much, the right, the last, just 等修饰时。

This is the very bus that I’m waiting for.

③当先行词是形容词最高级或先行词的前面有形容词最高级修饰时。

This is the most interesting film that I’ve ever seen. 这是我曾经看过的最有趣的电影。

④当先行词是序数词或它前面有序数词修饰时。

This train is the last that will go to Suzhou. 这是去苏州的最后一趟火车。

⑤当先行词既有人又有物时。

Do you know the things and persons that they are talking about?你知道他们正在谈论的人和事吗？

⑥当主句的主语是疑问句 who 或 which 时，

Which is the bike that you lost? 哪辆是你丢的自行车？

Who is the boy that won the gold medal? 赢得金牌的那个男孩是谁？

⑦有两个定语从句时，其中一个关系代词宜用 which,另外一个宜用 that.

They secretly built up a small factory, which produced things that could cause

pollution.

⑧当先行词在主句中作表语，而关系代词在从句中也作表语时。

Shanghai is no longer the city that it used to be. 上海不再是过去的那座城市 了。

⑨主句是 there be 句型且关系词在从句中作主语用，用 that 不用 which 引导。

There is a seat in the corner that is still available.

2. 当先行词指事或人时，定语从句中关系代词用 which 不用 that 的情况：

①在非限制性定语从句中，只用 which,不用 that

He broke my cup, which made me angry. 他打破了我的杯子，这使我很生气。

②当动词短语中的介词提前时，只用 which, 不用 that.

This is a house in which Lu Xun once lived. 这是鲁迅曾住过的房子。

注意：在一些固定搭配的动词短语中，由于动词和介词不可分割，因此不能把介词置于关系代词之前。

This is the pen(which/that) I’m looking for. 这是我正在寻找的那只钢笔。

3. 只用 who 而不用 that 引导定语从句的情况

①先行词是指人的不定代词，如 one, ones, anyone, no one, those, all, nobody,

anybody, none 等时，用 who 不用 that.

People all like those who have good manners. 人们都喜欢那些有礼貌的人。

②在 there be 结构中，先行词指人时，多用 who

There are some people who want to have holidays in Hainan. 有一些想去海南度假的人。

③在非限制定语从句中，指人且作主语时，用

who 不用 that

Professor Wang, who is over sixty, still works hard day and night.

4. 由 as 引导的定语从句

① such+名词+as…像…一样的，像…之类的
