一、定义
定语从句的定义，在复合句中，装饰某一专有名词或代词的从句叫定语从句。 比如： 1) The man who lives next to us is a fool.
2) You must buy me the house which is near Xiangshan. 上边几句中的the man和the house是定语从句所装饰的词，叫先行词，定语从句放到先行词的后边。
二、关系词(连词) 1.关系代词正确引导的定语从句 正确引导定语从句的关系词有关系代词：that, which, who (宾格whom, 所有格whose) 和关系副词where, when, why。关系词放到先行词和定语从句中间，起联接功效，另外还做定语从句的一个成份。
2.有关that, which的使用方法留意点 1)只有用that，无需which做为定语从句关系代词的状况 a)不定代词，如anything, nothing, the one, all, much, few, any, little等作先行词 There is nothing that I can do. I mean the one that was bought yesterday. b)先行词有the only, the very, the same, the last装饰 This is the very book that I want to find. The last place that I visited was the hospital. c)先行词为序数词、数词、修饰词高級时 This is the first composition that he has written in English. d)先行词不仅有人，又有物时 He talked about the teachers and schools that he had visited.
2)无需that, 仅用which的状况 a)正确引导非限定性定语从句时which The tree, which is four hundred years old, is very famous here. b)代词后用which We depend on the land from which we get our food. 3.关系副词正确引导的定语从句 关系副词可替代的先行词是時间、地址或原因的专有名词，在从句中作状语。 1)先行词是表明地址专有名词时(country, school, room…)，而关系词替代先行词在定语从句中当做地点状语，一般用where正确引导定语从句。还可以用代词 which的构造。特别注意的是which前的代词挑选是依据先行词与代词的配搭关联而定。 Beijing is the place in which (=where) I was born.

He wants to find the place in which (=where) he lived forty years ago. 2)先行词是表示时间专有名词时(year, month, day, night…)，而关系词替代先行词在定语 从句中当做时间状语，一般用when正确引导定语从句。还可以用代词 which的构造。特别注意的是when前的代词挑选是依据先行词与代词的配搭关联而定。 His father died that year in which (=when) he was born. I cannot forget the first day on which (=when) my family moved into the city.
3)先行词是the reason，而关系词替代先行词在定语从句中当做原因状语，一般用why正确引导定语从句。还可以用for which的构造。 Is this the reason for which (why) he refused our offer? 可是这儿要强调的是，假如代词和Which配搭在一起并不表明之上三种含意，则大家只有保存代词 Which的方式。如 I know English in which I wrote the love letter.
4.分辨关系代词与关系副词 方式一： 用关系代词，還是关系副词彻底在于从句中的谓语动词。及物动词后边无宾语，就务必要 求用关系代词;而连系动词则规定用关系副词。
