引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why关系词常有三个作用：1、引导定语从句2、代替先行词3、在定语从句中担当一个成分关系副词引导的定语从句1.关系副词也可以引导定语从句关系副词在从句中分别表示时间.地点或原因。

关系副词when在从句中充当时间状语，where 充当地点状语，why充当原因状语。

2. that可引导定语从句表示时间.地点或原因That有时可以代替关系副词 when, where 或者why引导定语从句表示时间.地点或原因，在 that引导的这种定语从句中，that也可以省去。

（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。

英语语法初中定语从句用法知识点归纳总结定语从句是英语语法中一个重要的内容，它可以起到修饰名词或代词的作用。

在初中英语学习中，学习定语从句的用法是必不可少的一部分。

下面是对初中阶段定语从句用法的知识点进行归纳总结。

一、定语从句的基本结构与用法定语从句由关系词引导，关系词有：who, whom, whose, which, that 等。

关系词在定语从句中担当某一成分的角色，分为主语关系词和宾语关系词。

1. 主语关系词引导的定语从句：- 关系代词：who, which, that- 关系副词：when, where, why例句：(1) The girl who is playing the piano is my sister.(2) The book which I bought yesterday is very interesting.(3) This is the reason why I am late.2. 宾语关系词引导的定语从句：- 关系代词：whom, which, that- 关系副词：when, where, why例句：(1) The girl whom I met at the party is my classmate.(2) The book which I am reading is very interesting.(3) This is the reason why I am late.二、定语从句的省略定语从句中的关系词在从句中作主语时，可以省略。

但如果关系词在从句中作宾语，不能省略。

例句：(1) The girl (who/that) I met at the party is my classmate.(2) The book (which/that) I am reading is very interesting.三、定语从句的连接词与先行词的关系定语从句中的连接词与先行词之间要保持一致，即在人称、数和性别上要保持一致。

定语从句详解及练习附答案第一部分:基础知识（一）．定语从句概述定语可以由形容词，代词，数词，名词，不定式，介词短语来充当。

如果是一个句子担任定语，那么这个句子就叫做定语从句，又可称为形容词性从句。

定语从句通常修饰某一名词或代词，被定语从句修饰的这一名词或代词叫先行词，它位于定语从句之前，定语从句在先行词后面，应尽量紧跟先行词。

定语从句的作用即在于对先行词进行限定说明或补充说明。

（二）．定语从句的引导词。

定语从句的引导词分为两类，关系代词（that, which, who, whom, whose ）和关系副词（when, where, why ），引导词在先行词和定语从句之间，既起连接作用，即连接先行词和定语从句，更重要的是，它又在定语从句中作一个成分。

（三）．关系代词1. that 指人，物，在从句中作主语，宾语，表语。

This is the photo that I took in the country.He is the singer that I met yesterday.2. which 指物，在从句中作主语，宾语，在非限定定语从句中充当定语，或者代替前句The film which we saw last night was moving.3. who 指人，在从句中作主语，宾语。

The person who visited our classroom yesterday was our new headmaster.The man who you just talked to is Tom.4. whom 指人，在从句中作宾语。

That is the professor whom you want to know.5. whose 指人，物，在从句中作定语，相当于先行词+ ’s, 后接一名词。

I know the boy whose parents are dead.I don’t like those cities whose roads are dirty.注：关系代词在从句中作宾语时可以省略。

初中英语定语从句知识点总结归纳1. 定语从句是在句子中作定语的从句，用来修饰和限定名词或代词。

2. 关系代词：- 关系代词在定语从句中作主语或宾语，代替先行词。

3. 关系副词：- 关系副词在定语从句中作状语，修饰先行词。

4. 定语从句的引导词的选择：- 条件：如果先行词是人，用关系代词who或关系副词where 可以引导定语从句；如果先行词是物，用关系代词that或关系副词where可以引导定语从句。

- 结构：如果关系代词在定语从句中作宾语，用关系代词that 或关系副词where；如果关系代词在定语从句中作主语，用关系代词who或which或关系副词where。

- 所有格：如果先行词是人，用关系代词whose可以引导定语从句；如果先行词是物，用关系代词of which可以引导定语从句。

5. 定语从句的位置：- 当定语从句修饰的是句子中的主语时，定语从句放在主句后面；- 当定语从句修饰的是句子中的宾语时，定语从句放在主句后面；- 当定语从句修饰的是句子中的宾语补足语时，定语从句放在主句后面；- 当定语从句修饰的是句子中的表语时，定语从句放在主句后面；- 当定语从句修饰的是句子中的状语时，定语从句放在主句前面或主句后面。

6. 注意点：- 不可省略的情况：关系代词在定语从句中作主语时，不能省略；关系副词在定语从句中作状语时，不能省略。

- 可以省略的情况：当定语从句的主语和主句的主语一致时，可以省略定语从句中的关系代词that或关系副词where。

7. 示例：- The boy who is reading a book is my brother. (关系代词who在定语从句中作主语)- The pen that I bought yesterday is missing. (关系代词that在定语从句中作宾语)- This is the place where I was born. (关系副词where在定语从句中作状语)参考以上内容，可以帮助你更好地理解和运用初中英语中的定语从句知识点。

定语从句知识点详解（初中英语专项复习）1. 根据定义定特点在复合句中, 修饰某一名词或代词的从句叫作定语从句。

两个句子之间通过关系代词(that, which, who, whom, whose) 或关系副词(when, where, why)连接起来。

定语从句前的那个被修饰的名词或代词叫作先行词。

如：Running Man is a very relaxing TV program which is popular among the young people. 主句：Running Man is a very relaxing TV program 从句：which is popular among the young people先行词：TV program 关系代词：which因此, 如果确定是考查定语从句, 我们就可以排除不是关系代词或关系副词的选项, 如：what。

2. 根据成分选连词在此过程中要掌握“三看”原则。

(1) 一看指人还是物先行词指人：that, who (曲靖：2016.39), whose, whom先行词指物：that (曲靖：2016.45), which, whose (2) 二看句中作何用① 当先行词是all, little, much, none, everything, anything, nothing等不定代词时(曲靖：2017.40)。

--- Tom told his mother all that had happened. 汤姆把发生的所有事情告诉了他的妈妈。

① 当先行词前面有the only, the very, the last等修饰时。

--- This is the only book that I can find. 这就是我能找到的唯一的一本书。

① 当序数词或形容词最高级修饰先行词时。

---The tallest player that plays football for our team is from Shanghai. 为我们足球队踢足球的那个最高的运动员来自上海。

E. g. I have many friends to whom I will send postcards.我有许多需要寄明信⽚的朋友先⾏词指物时先⾏词指物时，⼀般情况下，关系词that和which可以互换。

只⽤that不⽤which的情况：1. 先⾏词是指物的不定代词时，如all, little, few, something, anything, some等。

初中三大从句一、中考要求：宾语从句、定语从句、状语从句的用法是中考热点之一，主要考查三种从句的引导词的选择；宾语从句的语序和时态；状语从句主要考查时间状语从句、条件状语从句、因果状语从句，特别是条件状语从句的时态、so… that引导的结果状语从句和目的状语从句等。

二、知识要点：1. 宾语从句：在句子中起宾语作用的从句叫宾语从句，中考主要考查的知识点有三个：引导词、语序和时态。

宾语从句的引导词有三种：1）that；2）whether/ if；3）特殊疑问词What/ when/ where/ who等。

例如：He said that he could help me. 他说他能够帮助我。

Your mother asked if you could finish your work this week. 你妈妈问这个星期你能否完成工作。

Can you tell me when the sports meeting will begin？你能告诉我运动会将在什么时候开始吗？1) 以that引导的宾语从句：that引导的宾语从句一般都是由陈述句充当，引导词that没有实际意义，不在从句中作任何成分，that可以省略，而且从句成分齐全，句意完整。

Do you think (that) it will rain? 你认为天会下雨吗？He said (that) he could come on time. 他说他会准时来的。

2) 以whether或if引导的宾语从句：从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的，变成从句后，语序由原来的倒装语序变成陈述语序。

whether和if意思是“是否”。

Let us know whether / if you can finish the work before Friday.请让我们知道你是否能在星期五以前把工作做完。

I don’t care whether you like the story or not. 我不在乎你是否喜欢这个故事。
