定语从句，一个简单句跟在一名词或代词后（先行词）进行修饰限定，就叫做定语从句。接下来我们一起来看看河北中考英语定语从句基础知识。

1在复合句中做定语的从句称为定语从句，它可以用来修饰名词或代词。被定语从句修饰的名词或代词叫先行词。定语从句必须放在先行词后面。

2引导定语从句的词通常被称为关系词。关系词一般位于先行词与定语从句之间，且作为定语从句的一个成分。关系词又分为关系代词和关系副词。

I 关系代词引导的定语从句

关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。

1)who, whom, that

这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。例如：

Is he the man who/that wants to see you? 他就是你想见的人吗?(who/that在从句中作主语)

He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。(whom/that在从句中作宾语)

2) whose 用来指人或物，(只用作定语, 若指物，它还可以同of which互换)。例如：

They rushed over to help the man whose car had broken down.　那人车坏了，大家都跑过去帮忙。

Please pass me the book whose (of which) cover is green.　请递给我那本绿皮的书。

3)which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。例如：

A prosperity which / that had never been seen before appears in the countryside.

农村出现了前所未有的繁荣。(which / that在句中作宾语)

The package (which / that)you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作宾语)

II. 关系副词引导的定语从句

关系副词可代替的先行词是时间、地点或理由的名词，在从句中作状语。

1) 关系副词when, where, why的含义相当于"介词+ which"结构，因此常常和"介词+ which"结构交替使用。例如：

I will never forget the day when I met her. 我将永远不会忘记我见到她的那一天

Beijing is the place where(in which) I was born.　北京是我的出生地。

Is this the reason why (for which) he refused our offer?　这就是他拒绝我们帮助他的理由吗?

2)that代替关系副词，可以用于表示时间、地点、方式、理由的名词后取代when, where, why和"介词+ which"引导的定语从句，在口语中that常被省略。例如：

His father died the year (that / when / in which) he was born.　他父亲在他出生那年逝世了。

He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住过的地方。

III.判断关系代词与关系副词

方法一： 用关系代词，还是关系副词完全取决于从句中的谓语动词。及物动词后面无宾语，就必须要求用关系代词;而不及物动词则要求用关系副词。例如：

This is the mountain village where I stayed last year. 这是我去年呆过的山村。

I'll never forget the days when I worked together with you.我永远不会忘记与你共事的日子。

判断改错：

(错) This is the mountain village where I visited last year.

(错) I will never forget the days when I spent in the countryside.

(对) This is the mountain village (which) I visited last year.

(对) I'll never forget the days (which) I spent in the countryside.

习惯上总把表地点或时间的名词与关系副词 where, when联系在一起。此两题错在关系词的误用上。
