初中八年级下册英语开始大量接触定语、宾语及状语从句。句子成分会越来越复杂，长句复合句会越多，所以要大家一定要弄清楚在去背诵，理解才能应用。接下来会对三大从句做一个概述。今天对定语从句做一个简单介绍。
一、概念
1.定语从句：从句在整个句子中做定语，修饰先行词
2.关词词：
关系代词which that who whom whose as
关系副词 When. where.why
3、关系词的功能:
1)连接主句与从句
2)指代先行词
3)在从句中充当成分
4.先行词：被定语从句修饰的词，通常为名词或代饲
二、关系代词的用法
指代内容 所做成分. 是否可省略
That 人/物主/宾作宾可省
Which 物主/宾 作宾可省
Who 人 主/宾作宾可省
Whom 人宾可省
Whose.人/物的 定语 不可省
三、只能用that的情况
1)当先行词是形序词最高级，序数词，不定代词被他们修时或被它们修饰时
2）当先行词是 the only, the very,the right修饰时
3）当先行词是人+物时
4）当先行词是前有wHich疑问句时
eg: Which is the house that he Lives
四、先行词是the way时后跟that/in which/不填
eg: Do you know the way that he studlies?
五，关系代词做介词的宾语且宾语提前时
人+词+whom
物+介词+which
无其他情况且不可省略
六、whose引导的定从句和介词whom/which引导的定语从句的转换
eg.
This is the way Whose father is a teachey
This is the way of whom the father is a teacher.
This is the way the father of Whom is a teacher
七、关系代词as的使用
一般用下面等式
as We all know
as it known all
as Is said above
as is mentioned above
as Is reported in the newspaper
as is often the case
当先行词被 the same 或 such饰时只能用as
eg: He has the same book as I have
八、关系副词的用法
1.when时间状能
2.whee地点状形
3.why原因状语
副＝介+ which
The house where /in which I lived k here
The house that /which was destroyed is here
where:表示成模糊的抽象地点
eg: situation. conolition environment case. point
