复合句中对名词、代词、名词性短语或句子进行修饰和限定的从句叫定语从句。定语从句修饰的名词、代词等被称为先行词。定语从句由关系词引导。
一、关系代词引导的限制性定语从句1．引导定语从句的关系词有关系代词和关系副词。关系代词有that，which，wh，whm，whse，as等；关系副词有when，where，why等。关系词通常有下列作用：引导定语从句；代替先行词；在定语从句中充当一个成分。
2．定语从句分为限制性定语从句和非限制性定语从句。(1)限制性定语从句：所修饰的词表示一个特定的人或东西。如果去掉它，被修饰的词就失去意义，句子就不能成立或不完整。He is the man wh/that lives next dr.他就是住在隔壁的男子。(2)非限制性定语从句：由一个逗号将从句与先行词隔开，对所修饰的词作做进一步的说明。如果去掉它，句子的意思仍然完整。The children，wh were injured in a car accident，are being treated in the hspital nw.在车祸中受伤的孩子们正在医院接受治疗。
二、关系代词wh，whm，whse引导的定语从句1．wh指人，在定语从句中可以充当主语或宾语。先行词为指人的词(包括人名)、拟人化的动物和指人的人称代词或不定代词all，thse，few，ne等。The number f peple wh were killed in the disaster was ver 100.在那次灾难中丧生的人数超过了100。Danny was the man(wh)we rescued frm the ruins.丹尼是我们从废墟中救出来的那个人。
2．whm指人，在定语从句中作宾语，若在从句中作介词的宾语，介词可用于whm之前，也可以位于句末。Rse is the persn(wh/whm) yu shuld care abut.罗丝是你应该关心的人。There are many peple with whm yu can share yur feelings.你可以与许多人分享自己的感受。
3．whse既可指人，也可指物，表示“所属”关系，whse在定语从句中作定语，常与它所修饰的名词一起出现在从句的句首。I knw the persn whse huse was destryed in the earthquake.我认识那个在地震中被摧毁了房子的人。He lives in a huse whse garden is attractive.他住在一个有着美丽花园的房子里。
[即时训练]　用关系代词填空①Thse ____ want t jin in the activity sign up，please.②A dctr with ______ my father wrked last year has gne abrad.③Any student ______ family is t pr t let him g t schl can get help frm the gvernment in that cuntry.④I'd really like t find a friend ______ I can trust cmpletely.
三、which和that引导的定语从句1．which指物，在定语从句中作主语或宾语，或在从句中作介词的宾语。先行词为表示事物或动物的名词或表示职业的名词。The yung man was very happy t find the gld ring(which)he had lst.那个年轻人找到了丢失的金戒指，非常高兴。Everywhere I saw，there were buildings which had been destryed by the earthquake.我看到到处都是被地震毁掉的建筑。The gld medal(which)she wn has been given t her ld schl.她获得的那块金牌已经被送给她的母校了。
2．that既可指人，也可指物，在定语从句中作主语或宾语，作宾语时可以省略。先行词是表示人(不包括人名)、事物或动物的名词。习惯上指人多用wh/whm，指物多用which。He is the nly student that understands English well.(that指人，作主语)他是唯一一个会英语的学生。There is ne thing that keeps me wrried.(that指物，作主语)有一件事一直使我不安。
[温馨提示]　(1)关系代词指代先行词，在定语从句中充当主语、宾语或定语，因此定语从句中不能再出现关系代词所替代的名词或代词。The film(that/which)we saw it last night is very frightening.(×)The film(that/which)we saw last night is very frightening.(√)(2)关系代词在从句中作主语时不能省略，作宾语时可以省略。Is that the girl(whm/wh/that)yu referred t the ther day?那就是你前几天所提到的女孩吗？
[即时训练]　用关系代词填空①The ld twn has narrw streets and small huses _________ are built clse t each ther.②There are sme athletes _______________ I want yu t meet.③D yu still remember the chicken farm ___________ we visited three mnths ag?
wh/whm/that
四、关系词只用that而不用which的情况1．当先行词为all，everything，nthing，anything，much等不定代词时。Nthing that has been learnt is ever cmpletely frgtten.任何学过的东西都不会被全部忘记。All that can be dne has been dne.所有能做的都做了。2．当先行词是序数词或形容词最高级或被序数词或形容词最高级修饰时。This is the first tw-strey bus that runs in ur city.这是第一辆运行于我市的双层公交车。This is the mst shcking news that I have ever heard.这是我曾经听过的最令人震惊的消息。
3．当先行词被all，every，n，any，the nly，the very，the same，the right等修饰时。This is the very scarf that Mther has been lking fr.这就是妈妈一直在找的那条围巾。Music is the nly thing that interests me.音乐是唯一令我感兴趣的东西。4．当先行词既有人又有物时。We ften talk abut the persns and things that we remember.我们常常谈起我们记得的那些人和事。She described in her cmpsitin the peple and places that impressed her mst.她在作文中描述了令她印象最深的一些人和地方。
