初三英語定語從句講解及練習(xí)題

1、1初三英語定語從句講解及練習(xí)題在復(fù)合句中修飾名詞和代詞的從句叫做定語從句。被定語從句修飾的名詞或代詞叫做先行詞。引導(dǎo)定語從句的關(guān)系代詞有whowhosewhomwhichthat。引導(dǎo)定語從句的關(guān)系副詞有whenwherewhy。關(guān)系代詞在定語從句中做主語，賓語，定語。關(guān)系副詞在定語從句中做狀語。一、who引導(dǎo)的定語從句who在從句中做主語(口語中也可做賓語)，修飾表示人的先行詞。Thisisthemanwhohelpedme.Theb

2、oywhowhomwesawyesterdayisJohn’sbrother.二、whom引導(dǎo)的定語從句whom在從句中作賓語修飾表示人的先行詞，口語中可以省略。Thedoct(whom)youarelookingfisintheroom.Theperson(whom)youjusttalkedtoisMr.Li.=ThepersontowhomyoujusttalkedisMr.Li.(介詞后whom不能省略)Thebabieswho

3、mthenursesarelookingafterareveryhealthy.(固定短語中的介詞一般不能拆開，仍放在動(dòng)詞之后。lookflookaftertakecareofputontakeoff…)三、whose引導(dǎo)的定語從句whose在從句中作定語，修飾表示人或物的先行詞。DoyouknowthewomanwhosenameisMary.Passmethedictionarywhosecoverisblack.Hehasafri

4、endwhosefatherisadoct.四、that引導(dǎo)的定語從句，that在從句中做主語或賓語、修飾表示人或物的先行詞。作賓語時(shí)可省略不能放在介詞后面作賓語.(that指人時(shí)，相當(dāng)于who或者whom；指物時(shí)，相當(dāng)于which)Theletter(thatwhich)Ireceivedwasfrommyfather.Ican’tfindtheletterthatwhichcamethismning.Doyoustillrememb

5、erthedays(thatwhich)wespenttogetherThisisthemanthatwhohelpedme.Thehouse(thatwhich)weliveinisnotlarge.=Thehouseinwhichweliveisnotlarge.Thedoct(thatwhomwho)youarelookingfisintheroom.五、which引導(dǎo)的定語從句，which在從句中做主語，也可做賓語，或介詞的賓語

6、，修飾3ShanghaiisthecitywhereIwasbn.九、Why引導(dǎo)的定語從句，why做原因狀語。Iknowthereasonwhyhecamelate.(f＋which可以代替why)Thereasonwhyfwhichhewaslatewasthathewasill.十、關(guān)系代詞在從句中作主語，謂語動(dòng)詞的數(shù)與先行詞保持一致。ThestudentwhoisgoodatEnglishstudieshard.Thestuden

7、tswhoaregoodatEnglishstudyhard.十一、定語從句可分為兩大類，即限制性定語從句和非限制性定語從句。①限制性定語從句是先行詞在意義上不可缺少的定語，如果去掉的話，主句的意思就不完整，意義就表述不明。這種句型一般定語從句緊接先行詞（不用逗號(hào)隔開）如：Iwastheonlypersoninmyofficewhowasinvited.②非限制性定語從句。它與主句的關(guān)系不十分密切，只是對(duì)先行詞起補(bǔ)充、說明的作用，

8、也就是說即便去掉定語從句，句意也不受影響。主從句之間常用逗號(hào)分開，且非限制性定語從句不能用that來引導(dǎo)。ThiswastheAmericanCivilWarwhichlasted4yearsbefetheNthwonintheend.一、用關(guān)系代詞（that、which、who、whom、whose）或關(guān)系副詞（when、where、why）填空。1Thisistheman_______________wantstoseeyou.2T
