as(主語/賓語/表語)that,which(主語、賓語),whose,aswhere(地點狀語)when(時間狀語)why(原因狀語)Ps:關(guān)系詞在從句中做狀語時,連接詞有時可以用介詞+which/whom來替換關(guān)系副詞

定語從句可分為限制性定語從句和非限制性定語從句。定語從句的分類：1.

限制性定語從句它是對先行詞作修飾、限制,

從句與主句的關(guān)系十分密切,

如果去掉,

主句的意思就不完整或失去意義。2.

非限制性定語從句它是對先行詞作附加補充說明,從句與主句的關(guān)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.1.形式不同二、限制性和非限制性定語從句的區(qū)別限制性定語從句:與主句之間無逗號隔開；非限制性定語從句:與主句之間有逗號隔開。Hisdaughter,whoisinShenzhennow,iscominghomenextweek.People

whotakephysicalexerciseregularlylivelonger.Heisthemanwholivesnexttome.他就是住在我隔壁的那個人。Heisawarm-heartedman,wholivesnexttome.他是個熱心腸的人,住在我的隔壁。2.翻譯不同限制性定語從句:一般先譯從句,后譯先行詞,即把從句翻譯在它所修飾的先行詞前,譯為“…的＋先行詞”。非限制性定語從句:一般先譯主句,后譯從句,翻譯成兩個分句。3.先行詞不同限制性定語從句:可以修飾名詞或代詞；

非限制性定語從句:可以修飾名詞或代詞,也可以修飾整個句子,DoyourememberthemanwhotaughtusEnglish?Sheandherfamilybicycletowork,whichhelpsthemkeepfit.Mr.White,whomyoumetyesterday,isoneofmyoldfriends.(非限制性定語從句,whom在從句中作賓語,不能省略）4.關(guān)系詞不同在限制性定語從句中,關(guān)系代詞作賓語時可以省略；在非限制性定語從句中,所有關(guān)系詞都不可省略。三、使用非限制性定語從句時的注意事項1.that不能引導非限制性定語從句。

在非限制性定語從句中,用who,whom指代人,用which指代物。ShewasveryfondofspeakingFrench,whichindeedshespokewell.Ihadtoldthemthereason,forwhichIdidn’tattendthemeeting.2.非限制性定語從句表原因時,不能用why引導,而用forwhich代替why。三、使用非限制性定語從句時的注意事項TheywenttoLondon,wheretheylivedforsixmonths.3.當先行詞是世界上獨一無二的事物或?qū)Ｓ忻~時,其后的定語從句通常是非限制性定語從句。4.當先行詞是唯一親屬,使用非限制性定語從句。ProfessorWanghasason,whoworksin

Beijing.三、使用非限制性定語從句時的注意事項5.
