被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。
二、定语从句的关系词引导定语从句的关系词有关系代词和关系副词，常见的关系代词包括that，which，who（宾格whom，所有格whose）等，关系副词包括where，when，why等。
关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。
三、定语从句的分类根据定语从句与先行词的关系，定语从句可分为限制性定语从句及非限制性定语从句。
限制性定语从句紧跟先行词，主句与从句不用逗号分开，从句不可省去，非限制性定语从句主句与从句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
四、关系代词的用法1. that 既可以用于指人，也可以用于指物。
在从句中作主语或宾语，作主语时不可省略，作宾语可省略。
例如：Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。
（that作主语）The coat （that） I put on the desk is blue.我放在桌子上的那件外套是蓝色的。
（that作宾语）2.which用于指物，在句中作主语或宾语，作主语不可省略，作宾语可省略。
例如：The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。
（作主语）The film （which） we saw last night was wonderful. 我们昨天晚上看的那部电影很好看。
（作宾语）3.who，whom用于指人，who 用作主语，whom用作宾语。
在口语中，有时可用who代替whom，也可省略。
例如：The girl who often helps me with my English is from England.经常在英语方面帮助我的那个女孩是英国人。

定语从句专题复习定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose(一般指人), that（指人或物）, which(指物)等。
关系副词有： when（时间）, where(地点), why（原因）等。
（1）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，在从句中所起作用如下：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/who/that在从句中作saw的宾语,可以省略）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（封面）is green.请递给我那本绿皮的书。
③ which, that它们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：Rosa likes music that/which is quite and gentle.（which / that在句中作宾语）This is the book (that/which) I'm looking for.（which / that在句中作look for 的宾语）（2）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 when, where, why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：Do you remember the day when I saw you(你还记得我见到你的那一天吗)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that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。
（3）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.I’ll never forget the days when I worked together with you.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。
方法二：准确判断先行词在定语从句中的成分（主、谓、宾、定、状），也能正确选择出关系代词/关系副词。
例1：Is this museum _____ you visited a few days ageA. whereB. thatC. on whichD. the one例2：Is this the museum _____ the exhibition was held.A. whereB. thatC. on whichD. the one答案：例1 D；例2 A例1变为肯定句：This museum is _____ you visited a few days ago.例2变为肯定句：This is the museum _____ the exhibition was held.在句1中，所缺部分为宾语，而where, that, on which都不能起到宾语的作用，只有the one既做了主句的表语，又可做从句的宾语，可以省略关系代词，所以应选D。
而句2中，主、谓、宾俱全，从句部分为句子的状语表地点，既可用副词where，又因 in the museum 词组，可用介词in + which 引导地点状语。
而此题中，介词on 用的不对，所以选A。
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词（who, whom, that, which, whose）；先行词在从句中做状语时，应选择关系副词（where 地点状语，when 时间状语，why 原因状语）。
（4）介词+关系词①介词后面的关系词不能省略。
② that前不能有介词。
③某些在从句中充当时间，地点或原因状语的“介词+关系词”结构可以同关系副词when 和where 互换。
This is the house in which I lived two years ago.This is the house where I lived two years ago.Do you remember the day on which you joined our clubDo you remember the day when you joined our club（7）关系代词that 的用法①不用that的情况a. 在引导非限定性定语从句时。
The tree, which（不能用that）is four hundred years old, is very famous here.b. 介词后不能用。
We depend on the land from which（不能用that） we get our food.②只能用that作为定语从句的关系代词的情况a. 在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
b. 先行词有the only, the very , the last, the same 等修饰时修饰时，只用that。
c. 先行词为序数词、数词、形容词最高级时，只用that。
d. 先行词既有人，又有物时。
举例：All that is needed is a supply of oil. 所需的只是供油问题。
(a)Finally, the thief handed everything that he had stolen to the police. (a)那贼最终把偷的全部东西交给了警察。
