Ⅰ.定义

定语从句，起形容词的作用，在句中常用来修饰名词或代词。被修饰的词称为先行词,引导定语从句的词称为关系词,关系词的作

用一是放在先行词与定语从句中间起引导作用;二是在意义上代替先行词,并在从句中充当一个成分。其中关系代词：

who,whom,whose,which,that,as；关系副词：when,where,why。

eg.Sheisthegirlwhosingsbestofall.

Thepenwhichmyunclegavemeismissing.

Helivesinahousewhosewindowsfacesouth.

Thefactorywheremyfatherworksisintheeastofthecity.

Perhapsthedaywillewhenpeoplewillbeabletobreathecleanairinci ties.

Ⅱ.关系代词

1.先行词是人，作主语，关系代词用who,that

eg.Heisaman（）neverleavestoday’sworktilltomorrow.

Theboy()isstandingthereismycousin.

2.先行词是人，作宾语，关系代词用whom,who,that,

eg.Hereistheman()you’vebeenexpectingtomeet.

Theman()youmetyesterdayisMr.Smith.

3.先行词是物，作主语，关系代词用which,that

eg.Thetrain（）hasjustleftisforGuangzhou.

Childrenliketoreadbooks()havewonderfulpictures.

4.先行词是物，作宾语，关系代词用which,that,或省略

eg.Thebook()youborrowedyesterdayisreallyinteresting. Thepen()myunclegavemeismissing.

5.先行词是人、物，作定语，关系代词用whose

eg.Heistheprofessor()namewasJackson.

China,（）

populationisthelargestintheworld,isdevelopingveryfast.

Ⅲ.关系副词

1.先行词是表示时间的名词，在定从中作时间状语，关系代词用when

eg.Ican’trememberthedate()hewentabroad.

I’llneverforgettheday()Ijoinedthearmy.

2.先行词是表示地点的名词，在定从中作地点状语，关系代词用where;其中注意表示抽象概念的地点名词，如，situation、stage、degree、point等表示方面或程度时，也需用where

eg.Thisisthevillage（）UncleWangoncelived. Theyhavereachedthepoint()theyhavetoseparatewitheachother.

He’

sgothimselfintoadangeroussituation()heislikelytolosecontrol overtheplane.

3.先行词是reason，在定从中作原因状语，关系代词用why eg.Idon’tknowthereason()hewaslate.

Noneofusknowthereason()Tomwasabsentfromthemeeting.

4.引导定语从句的关系副词也可以用“适当介词+which”来代替。

eg.October1,1949wasthedaywhen（=）thePeople’sRepublicofChinawasfounded.

Thisisthefactorywhere（=）weworkedayearago.

Idon’tbelievethereasonwhy(=)hewaslateforschool.

Ⅳ.关系代词that&which的区别:

⒈只用that的情况

①先行词为all,everything,anything,nothing,little,much 等不定代词时。

eg.Thereisnothing()canpreventhimfromdoingit.

②先行词被any,only,few,no,very,little等修饰时。

eg.Thisistheverybook()I’mlookingfor.

③先行词被形容词最高级或序数词修饰时。

eg.Thefirstplace()theyvisitedinGuilinwasElephantTrunkHill.

Thisisthebestfilm()Ihaveeverseen.

④先行词既有人又有物时。

eg.Hetalkedaboutthingsandpersons()theyrememberedintheschool .

⑤先行词被theonly,thevery修饰时。

eg.Mr.Smithistheonlyforeigner()heknows.

⑥句中已有who或which,为了避免重复时。

eg.Whoistheman()isstandingbesideTom?

⒉不能用that的情况：

①引导非限制性定语从句；

eg.Hehadfailedinthemathsexam,()madehisfatherveryangry.

②介词+关系代词。

eg.Thisistheroomin（）myfatherlivedlastyear.

Ⅴ.as引导定语从句时的用法(as相当于that&which)

①as引导限制性定语从句通常用于thesame…as,such…as结

构中。

eg.Thisisthesamebook()Ilentyou.

Suchmachines()areusedinourworkshoparemadeinChina.

②as引导非限制性定语从句既可放在主句之前，也可放在主句之后，位置灵活，用来修饰整个句子。通常用下列句型：
