初中定语从句讲解Complexsentence复合句：由连词连接两个或多个主谓结构的句子，其中一个主谓结构是句子的主要部分（主句），另一个或一个以上的主谓结构只在句子中作某个成分（如主语、宾语、表语、定语、状语、同位语）。复合句=主句+定语从句一个主谓结构是句子的主要部分（主句）另一个或一个以上的主谓结构只在句子中作某个成分（定语）Thestudents(whodonotstudyhard)willnotpasstheexam.主句主语从句主语从句谓语结构主句谓语结构Themanwholivesnexttousisapoliceman.先行词______________________关系词___定语从句什么是定语从句呢？答案：修饰前面某一名词或代词的从句叫定语从句。结构：先行词+关系词+句子注意：关系词=先行词，关系词与先行词在数上必须保持一致被修饰的词叫先行词Attributiveclause:限制性定语从句restrictive非限制性定语从句non-restrictive是先行词在意义上不可缺少的定语，如果去掉，主句的意思就不完整或失去意义。这种从句和主句关系十分密切，写时不用逗号分开。和主句关系不很密切，只是对先行词作些附加说明，如果去掉，主句的意思仍然清楚。这种从句，写时往往逗号分开。Iwastheonlypersonwhowasinvited.inmyofficeJenny,withwhomIplayedtabletennisyesterday,livesinmynextroom.Themanwhocamehereyesterdayhascomeagain.ThatisMr.Wang,whosedaughterteachesEnglishatamiddleschool.注意：引导非限制性定语从句的关系代词不可用that，指人时用who(主语),whom(宾语)，指物时须用which.在句子中作定语，修饰名词或代词的从句。这种从句由关系代词或关系副词引导，并作句子成分。定语从句还叫做嵌入句，因形容词定语，所以又称之为形容词性从句。Attributiveclause:定语从句的位置：通常在先行词（在主句中）后。定语从句的引导词关系代词关系副词指人指物who(主语、宾语)，whom(宾语)，that(主语、宾语),whose(定语)that(主语、宾语),which(主语、宾语)whose(定语)where(地点状语)when(时间状语)why(原因状语)关系代词that,which引导的定语从句:如果先行词是表示物的名词或代词，关系代词应用that、which.(作主语或宾语)Thisisadream.Thedreamwillnevercometrue.Thisisadreamwhich/thatwillnevercometrue.Thedoghasbeenfound.Thedogwaslost.Thedogwhichwaslosthasbeenfound.Practise:Thisisthehousewhichisforsale.2.Thebookwhichislyingonthefloorismine.which/that作主语.(不能省)（作主语）which/that作宾语：（可省略）Thisisthecard.I’vejustreceivedthecard.Thisisthecard(which/that)I’vejustreceived.Practise:Thisisthemistake(which/that)Ialwaysmake.Istillkeeptheletters(which)shewrotetome.Ilostthepen(which)myfatherboughtme.（作宾语）关系代词who,that,whom引导的定语从句:如果先行词是表示人的名词或代词，关系代词应用who,that(作主语或宾语)whom(作宾语)who/that作主语.(不能省)Thisisthefilmstar.ThefilmstarisverypopularinChina.ThisisthefilmstarwhoisverypopularinChina.(作主语)TheboywhobrokethewindowiscalledRoy.Doyouknowthemanwhospokeatthemeetingyesterday?Thegirlwhoiswateringtheflowersismycousin./thatwho/whom/that作宾语：(可省略)Themanisafamouswriter.Hedescribedthemanjustnow.Theman(who/whom/that)hedescribedjustnowisafamouswriter.(作宾语）Theboywho(m)I‘mlookingforismyfriend.Thethiefhasbeensenttoprison.Thepolicecaughtthethieflastnight.Thethiefwhomthepolicecaughtlastnighthasbeensenttoprison.小结：that－既可指人，也可指物，作主语，不能省略；作宾语，可以省略。which－指物，作主语，不能省略；作宾语，可以省略.who－指人，作主语，不能省略；作宾语，可以省略,（常用whom）注:当关系代词在定语从句中作主语时,定语从句的谓语动词形式由先行词定。Amatchinggame！！！Matchthetwosentences1.I’mreadingabook.ThebookisaboutBillGates._______________________________________2.Heisateacher.TheteacherteachesusChinese._______________________________________3.Idon’tliketheman.Heissmoking.____________________________________4.Whereisthepicture?Youboughtitlastweek._______________________________________I’mreadingabookthat/whichisaboutBillGates.Heisateacherwho/thatteachesusChinese.Idon’tlikethemanwhoissmoking.Whereisthepicturethatyouboughtlastweek?简单句与复合句的互换1.Thatmanismyfather.Heistalkingtoourteacher.简单句复合句Themantalkingtoourteacherismyfather.Themanwhoistalkingtoourteacherismyfather.2.Ilikethebooks.ThebookswerewrittenbyLuXun.简单句复合句IlikethebookswrittenbyLuxun.IlikethebookswhichiswrittenbyLuxun.3.Chinaisacountry.Ithasalonghistory.4.Heisaboy.Theboyhasconfidence.有时只能用that,不用which,常见的情况有六种：当先行词是all,any,few,little,none,anything,everything,nothing,everybody,nobody,everyone,noone或被它们修饰时。That’sallthatIknow.IsthereanythingthatIcandoforyou?Heansweredfewquestionsthattheteacherasked.2.当先行词被形容词最高级或序数词修饰时ThatisthemostinterestingbookthatIhaveeverread.ThefirstthingthatIshoulddoistoreviewmylessons.3.当先行词有thevery,theonly,thesame等修饰时。That’stheonlythingthatIcandonow.Thesearetheverywordsthatheused.4.当主句以who或which开头时，定语从句的关系词用that,而不用which或who.Whoisthegirlthatspoketoyoujustnow?Whichisthepenthatyoulost?5.先行词同时包括人或物时，关系词用that.ThemanandhisdogthatIalwaysmeetarestandingbythegate.⑥先行词是疑问词who,which,what时，定语从句用that而不用who,(whom)和which引导。Whoisthepersonthatisstandingatthegate?Whichofusthatknowssomethingaboutphysicsdoesnotknowthis?Whatthatisonthetablebelongstome?⑦当关系代词在从句中作表语时：Maryisnolongerthegirl(that)sheusedtobe.Chinaisnolongerthecountrythatitusedtobe.whose作定语,表示所属关系。（指人指物钧行）Theboyismyclassmate.Theboy’sfatherisapoliceman.Theboywhosefatherisapolicemanismyclassmate.①②Ilikethehouse.Itswindowsfacethesouth.Ilikethehousewhosewindowsfacethesouth.Achild_____parentsaredeadiscalledanorphan(孤儿).A.whoB.whoseC.who’sD.which例句赏析~~~~It’saninventionwhich/thatisusedforkeepingofftherain.《飘》It’sabookthat/whichwaswrittenbyMargaretMitchell.GonewiththewindIt’stheWallthat/whichwasbuiltbyChinesepeople.It’sananimalthat/which….It’sananimalthat/whichhasbignose.Exercise1:用关系代词填空Theboy____________isplayingping-pongismyclassmate.Thee-mail___________Ireceivedyesterdaywasfrommysister.Ihatepeople______________talkmuchbutdolittle.Thecar_____________myfatherboughtlastmonthisverybeautiful.who/that(which/that)who/that(which/that)5.Theman______hairiswhiteishisgrandfather.6.Isthereastudent_________fatherisabusinessman?7.Thisisthehousein________wehavelivedfor10years.8.I’veneverheardofthepeopleandthings________youtalkedaboutjustnow.whosewhosewhich(that)当先行词同时指人和物时，关系代词只能用that.Exe
