一、定语从句的定义
在复合句中，修饰某一名词、代词或某一句子起定语作用的从句叫定语从句。
例：He said he couldn't understand people who talked fat.
他说他听不懂那些说话快的人。
I like the books that I can understand.
我喜欢我能看懂的书。
上面两句中的people和books是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。
二、定语从句的关系词
引导定语从句的词有关系代词 that，which，who（宾格whom，所有格whose）和关系副词 where，when，why。关系代词或关系副词放在先行同和定语从句之间，起连接作用。同时又作定语从句的一个成分。
1. 关系代词
（1）定语从句中关系代词用that不用which的情况
① 当先行词中既有物又有人的时候。
例：I can't forget the people and the place that I know well.
我不能忘记我所熟悉的人和地方。
② 当先行词被the last，the very 或the only修饰时。
例：This is the very pen that I am looking for.
这正是我正在找的钢笔。
The only book that I want to read is missing.
我唯一想看的书不见了。
③ 当先行词有序数词或最高级修饰时。
例：You are the first person that I want to see.
你是我想要见的第一个人。
This is the best book that I can find.
这是我能找到的最好的一本书。
④ 当先行词被all，every，no等修饰时。
例：I want to read all the looks that were written by Lu Xun.
我想读所有鲁迅写的书。
⑤ 当先行词为anything，everything，noting等时。
例：Everything that we have seen in China is moving.
我们在中国看见的事情件件感人。
I have nothing that is worth reading.
我没有什么值得一读的东西。
（2）只能使用关系代词which的几种情况
① 只引导非限制性定语从句时。
例：There has just been a heavy rain, which makes the farmers delighted.
刚下过一场大雨，这让农民们很高兴。
② 关系代词跟在介词后时。
例：The house in which they are living was built 50 years ago.
他们现在居住的房子是50年前建的。
③ 先行词本身是that时。
例：What's that which flashed in the sky just now?
刚刚天空中一闪而过的是什么东西？
（3）关系代词的省略
一般情况下，关系代词作宾语时可以省略，但关系代词which、whom在从句中作介词的宾语并且介词位于关系代词前面时，不能省略。
例：I'll never forget the day on which I joined the club.
我永远不会忘记我加入俱乐部的那一天。
注意：
that、which、who在从句中作主语时，不能省略。
例：Who is the boy that is talking with our teacher?
正在和我们老师谈话的那个男孩是谁？
2. 关系副词的用法
（1）where指地点，在定语从句中作地点状语用来表示地点的定语从句。
例：Shanghai is the city where I was born.
（2）when引导定语从句表示时间。在定语从句中作时间状语也可作连接词用。
例：I still remember the day when I first came to the school.
注意：
表示时间“time”一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。
例：By the time you arrived in London, we had stayed there for two weeks.
到你到达伦敦的时候，我们在那里已经待了两个星期。
I still remember the first time I met her.
我仍然记得我第一次见到她。
（3）why指原因，在定语从句中作原因状语。
Please tell me the reason why you missed the plane.
注意：
关系副词引导的从句可以由"介词+关系代词"引导的从句替换。
① The reason why/ for which he refused the invitation is not clear.
② From the year when/in which he was going to school he began to know what he wanted when he grew up.
三、注意：
1. 介词后面的关系代词不能省略。
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, where和why 互换。
例：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 club?
Do you remember the day when you joined our club?
This is the reason why he came late.
This is the reason for which he came late.
