由关系代词 that, which, wh, whse
定语从句是中学一个非常重要的语法内容，对于阅读、写作尤其有用，同学们可以根据课本后的附录和本册书里的讲解，用“列表法”攻克这一语法重点。
1．定语从句：在复合句中，修饰某一名词或代词的从句叫
作定语从句。其作用相当于形容词。
2．先行词：被定语从句所修饰的名词或代词叫作先行词。3．关系词(引导词)：引导定语从句，连接主句与从句的词叫作关系词，分关系代词(that, which, wh, whse 等)和关系副词(when, where, why 等)两类。
注意：关系词的选用由先行词在定语从句中所充当的句子
4．限制性定语从句：是修饰先行词不可缺少的成分，去掉从句后整个句子的意义就不能成立或意思不清楚。限制性定语从句通常翻译为“……的”，置于先行词前。如：
The man wh rbbed him has been arrested.抢劫他的人已经被逮捕了。
It's the best htel that I have knwn.这是我所知道的最好的旅馆。
5．非限制性定语从句：对所修饰的词没有限定词义的作用，而是作一些补充说明，通常都用一个逗号把它和句子的其他部分分开，去掉非限制性定语从句对剩下部分没有太大的影响。在译成中文时，这个从句多译成一个并列句。如：
Peter, wh had been driving all day, suggested stpping at the
彼得开了一整天的车，他建议在下个镇停一停。
Ftball, which is a very exciting game, is played all ver the
wrld.全世界都在踢足球，它是一项令人兴奋的运动。
二、关系代词 that, which, wh, whse 的用法
三、关系代词的特殊用法
1．指代物时用 which 不用 that 的情况(1)当动词短语的介词提前时。如：
The pen with which he is writing was bught yesterday. 他正
用来写字的笔是昨天买的。(2)先行词本身为 that 时。如：
That which yu tld him is exciting.你告诉他的事是令人兴奋的。
(3)引导非限制性定语从句时(可修饰一个先行词，也可修饰
This is his huse, which is 50 years ld.
(which 指代“房子”)这是他的房子，有 50 多年了。
Tm was late again, which made his teacher angry.
(which 指代主句)汤姆又迟到了，这使他的老师很生气。2．只用 that 引导定语从句的情况
(1)先行词是不定代词，如 sme, all, much, little, smething,
everything, anything, nthing, nne, ne 时。如：
Is there anything that I can d fr yu?
That is all that I knw.这是我所知道的全部。
(2)先行词被 few, little, just, right, any, all, ne, n 等修饰时。
Yu can take any seat that is free.你可以在任何一个空位坐下。
There is little time that we can use.我们能用的时间几乎没有了。
I read all the bks that yu gave me.你给我的书我全都看完了。
(3)先行词被 the nly, the very, the same, the last 等修饰时。
This is the nly bk that can be useful fr us.这是唯一一本会对我们有用的书。
This is the very thing that I'm after.这正是我所追求的。
(4)先行词前被序数词或形容词最高级修饰时。如：
It is the first cmpsitin that I have written in English. 这是
我写的第一篇英语作文。
This is the mst interesting film that we have ever seen.这是
我们看过的最有意思的电影。
(5)先行词为数词时。如：
Yesterday I caught tw fish and put them in a basin f
water.Nw yu can see the tw that are still alive.
昨天我捉了两条鱼把它们放入了一盆水里。现在你可以看
(6)先行词中既有人又有物时。如：
He tld us the peple and the places that he had visited.他告诉我们他曾拜访过的人和参观过的地方。
(7)主句中有 wh, whm 或 which，关系代词宜用 that，以
Wh is the man that is reading the newspaper ver there ？那
个正在那边看报纸的人是谁？
Which is the bk that yu like best?你最喜欢哪本书？
(8)先行词为主句的表语而关系代词在定语从句中也作表
My hme village is n lnger the place that it used t be.我的家乡再也不是以前的那个小村庄了。
