一、概述
在复合句中，修饰某一名词或代词，用作定语的从句叫做定语从句(attributive clause)。被定语从句所修饰的词叫做先行词(antecedent)。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词who、whom、whose、which、that和关系副词when、where、why等。

二、关系代词和关系副词的功用能

巧记that和which的区别：
that，which可互换，下列请况勿照办；that情况比较多，不妨对你说一说；不定代词这路货，全用that准没错；先行词前被限制，千万不要用which；要用which别着急，介词提前逗隔离。

8、but 的用法
but既可指人，又可指物，常在定语从句中充当主语。but 本身含“否定”的意思，其作用相当于“that/which/who…not”。它前面的主句必须有“否定”的词(如no, not, little, few, hardly等)。but引导的肯定定语从句和否定的主句连用，通过双重否定达到强烈肯定的效果。
There is no mother but loves her own children.(=There is no mother that/who doesn’t love her children.)没有不爱自己子女的母亲。
There were few people but were hurt.(= There were few people who/that were not hurt.)几乎没有人不受伤。

2、where的用法
where指地点，修饰表地点的先行词，在定语从句中作地点状语。

注意：先行词为表示时间、地点的名词时，关系词不一定都用when或where。如果关系词在定语从句中作主语或宾语，就要用关系代词whch或that。

这是我们去年参观的那家工厂。

Do you know the reason why he left early?
你知道香椿苗他为什么早走吗？
巧记定语从句的用法
主句型，从句型，两种句子要完整。从句紧靠先行词，系词引导要弄清。定人用who或whom，定物which当先用。关系代词有that，定人定物有本领。定时间要用when，定地点where行。关系代(副)词作成分，唯作宾语可以省。
五、“介词＋关系代词”用法
1、介词+which在定语从句中分别作时间、地点和原因状语
介词+which在关系分句中分别作时间，地点和原因状语，代替相应的关系副词when，where和why。

注意：关系代词that在定语从句中作介词的宾语时，介词不能放在它的前面，只能放在从句中有关动词的后面。
The village that she lives in is 100 metres away. 她住在100米远的土工布村庄里。
2、介词+which(指物)/whom(指人)在定语从句中作地点状语
介词+which(指物)/whom(指人)在关系分句中作地点状语，表示存在关系，关系分句主谓常须倒置。
