as(主语/宾语/表语)that,which(主语、宾语),whose,aswhere(地点状语)when(时间状语)why(原因状语)Ps:关系词在从句中做状语时,连接词有时可以用介词+which/whom来替换关系副词

定语从句可分为限制性定语从句和非限制性定语从句。定语从句的分类：1.

限制性定语从句它是对先行词作修饰、限制,

从句与主句的关系十分密切,

如果去掉,

主句的意思就不完整或失去意义。2.

非限制性定语从句它是对先行词作附加补充说明,从句与主句的关系不是很密切,如果去掉,主句的意思仍然清楚、完整。Hisdaughter,whoisinShenzhennow,iscominghomenextweek.People

whotakephysicalexerciseregularlylivelonger.Heisthemanwholivesnexttome.他就是住在我隔壁的那个人。Heisawarm-heartedman,wholivesnexttome.他是个热心肠的人,住在我的隔壁。2.翻译不同限制性定语从句:一般先译从句,后译先行词,即把从句翻译在它所修饰的先行词前,译为“…的＋先行词”。非限制性定语从句:一般先译主句,后译从句,翻译成两个分句。3.先行词不同限制性定语从句:可以修饰名词或代词；

非限制性定语从句:可以修饰名词或代词,也可以修饰整个句子,DoyourememberthemanwhotaughtusEnglish?Sheandherfamilybicycletowork,whichhelpsthemkeepfit.Mr.White,whomyoumetyesterday,isoneofmyoldfriends.(非限制性定语从句,whom在从句中作宾语,不能省略）4.关系词不同在限制性定语从句中,关系代词作宾语时可以省略；在非限制性定语从句中,所有关系词都不可省略。三、使用非限制性定语从句时的注意事项1.that不能引导非限制性定语从句。

在非限制性定语从句中,用who,whom指代人,用which指代物。ShewasveryfondofspeakingFrench,whichindeedshespokewell.Ihadtoldthemthereason,forwhichIdidn’tattendthemeeting.2.非限制性定语从句表原因时,不能用why引导,而用forwhich代替why。三、使用非限制性定语从句时的注意事项TheywenttoLondon,wheretheylivedforsixmonths.3.当先行词是世界上独一无二的事物或专有名词时,其后的定语从句通常是非限制性定语从句。4.当先行词是唯一亲属,使用非限制性定语从句。ProfessorWanghasason,whoworksin

Beijing.三、使用非限制性定语从句时的注意事项5.
