定语从句在句中作定语,用来修饰某个名词或代词,这个名词或代词叫先行词,而定语从句位于先行词的后面。用来引导定语从句的词叫做关系词。关系词分关系代词(that,which,who,whom,whose)和关系副词(when,where,why)。关系代词引导的定语从句关系词引导定语从句,指代先行词,并在从句中作一定成分,如作主语、宾语或状语等。用来引导定语从句的关系代词有that,which,who,whom,whose。本单元我们重点讲解that,who,whom,which和whose引导的定语从句。◆1.that引导的定语从句that引导定语从句时,既可以指人,也可以指物,在从句中可以作主语或宾语。Heisapersonthatdoeswhathesays.(person是先行词,that在从句中作主语)他是一个说话算数的人。ThecatthatIboughtyesterdayisill.(cat是先行词,that在从句中作宾语)我昨天买的那只猫病了。◆2.who引导的定语从句who引导定语从句时只能指人,在从句中可以作主语或宾语。Afriendwhohelpsyouwhenyouhavetroubleisarealfriend.(friend是先行词,who在从句中作主语)在你有困难时帮助你的朋友才是真正的朋友。3.whom也可以引导定语从句,在从句中只能作宾语,有时可以和who互换,但介词后只能用whom,不能用who。Heisthemanwho/whomIhavebeenlookingfor.=HeisthemanforwhomIhavebeenlooking.他就是我一直在找的人。◆4.which引导的定语从句which引导定语从句时,只能指物,在从句中可以作主语或宾语。Iwanttotakeawaythebookwhichyoushowedmeyesterday.(book是先行词,which在从句中作宾语)我想带走你昨天给我看的那本书。◆5.whose引导的定语从句whose引导定语从句时,既能指人也能指物,在从句中可以作定语。Thebookwhosecolorisblueismysister's.Ihaveabrotherwhosehairislong.注意:◆在由that,who和which引导的定语从句中,当它们在从句中作主语时,都不可以省略；作宾语时,都可以省略。◆介词后面只能用which或whom,不能用that或who。Therearelotsofthings(that)Ineedtopreparebeforethetrip.Doyouknowthegirlwho/thatissingingintheclassroom?Thisisthebiggestfish(that)Ihaveeverseen.Itisthesingerstarwho…isagirl.isfromHongKong.makesfacewithafishmouth.GuessquicklyItisthebasketballplayerwho…isaboy.istallandhandsome.livesinAmerica.GuessquicklyDescribeonepersonintheclassroomandletothersguesswhohe/sheis.Ⅰ.用that,who,which或whom填空1.Alicelikessingers_________writetheirownmusic.2.Generally,oldpeoplelikemusic_______isquietandgentle.3.Thegirl_______________youmetjustnowinthestreetismyfriend.4.Thisistheschoolin_______Istudiedtwoyearsago.5.Themanwith_______myfatheristalkingoverthereisourheadteacher.that/whothat/whichthat/who/whomwhichwhomII.根据句意,用正确的关系代词填空。1.Heistheman__________isreadytohelpothers.2.Thegirl________________Ispoketojustnowismyfriend.3.Thedress___________youboughtinthecitymallismadeofsilk.4.Billlikesmusic___________hecansingalongwith.that/whothat/who/whomthat/whichthat/which5.Thisisthevillage__________Iusedtolivein.6.Womenalwayslikebuyingmanythings_____________theydon’tneedatall.7.I’mstudyingasubject___________Iamveryinterestedin.8.Thegirlwith________Iwentshoppingyesterdayismycousin.that/whichthat/whichthat/whichwhom注意:◆关系词只能用that的情况:a.先行词被序数词或形容词最高级所修饰,或本身是序数词、基数词、形容词最高级时,只能用that,而不用which。例如:Hewasthefirstpersonthatpassedtheexam.b.被修饰的先行词为all,any,much,many,everything,anything,none,theone等不定代词时,只能用that,而不用which。例如:Isthereanythingthatyouwanttobuyintheshop?c.先行词被theonly,thevery,thesame,thelast,little,few等词修饰时,只能用that,而不用which。例如:ThisisthesamebikethatIlost.d.先行词里同时含有人或物时,只能用that,而不用which。例如:IcanrememberwellthepersonsandsomepicturesthatIsawintheroom.e.以wh...
