定語從句（二）修飾物體時關系代詞that和which的區分只能使用which的情況非限制性定語從句中。在介詞之后。當主句中的主語被that修飾時。2.使用that的情況：當先行詞是nothing,something,anything,all,each等不定代詞時。當先行詞被all,any,some,no,not,every,each等修飾時。當先行詞被形容詞最高級、序數詞所修飾時。主句是以which或who開頭的特殊疑問句時eg.Whoisthewomanthatwaspraisedatthemeeting?當先行詞在從句和主句中都作表語時,無論先行詞是人還是物.eg.Beijingisnolongerthecountrythatshewas.如有兩個定語從句,其中一個已用which引導,另一個宜用that.在therebe句型中,只用that.eg.Thereisabookshelfinthecornerthatisfullofbooks.當先行詞被thevery,thelast,thenext,theonly等詞修飾時。eg.ThisistheverywatchthatIlostyesterday.當先行詞又有人又有物時。eg.IstillrememberthethingsandthepersonsthatImetinthecollege.修飾人時關系代詞that和who,whom的區分當主句中的主語是who時，只能用that。eg.Whoistheoldmanthatisstandingoverthere?在非限制性定語從句中以及介詞后面時只能用who或者whom。eg.Thereare50studentsintheclass,mostofwhomaregirls.關系代詞whose既能修飾人，也能修飾物，在定語從句中充當定語，修飾先行詞。eg.SheisthegirlwhoseFrenchsoundsverybeautiful.Maryhasalovelydog,whosehairturnsoutwhite.關系代詞as與which引導非限制性定語從句的區別1.位置：as從句可在主句前或主句后，而which從句只可在主句后.2.意義：as從句常是一些固定結構,(如asisknowntoall,asweexpected,aseverybodyknows等,而且譯為”正如….,恰如…”.)thesame…as,such…as,和……一樣.which從句多為對主句的一種評價看法或因果關系，沒有結構要求。Hefailedintheexam,whichmadehisparentssad.Aswehadexpected,hefailedintheexam.注意:當先行詞被thesame修飾時,that也可引導定語從句,但意義有所不同。thesame...as指同樣或同類的事物；thesame...that指同一個事物。ThisisthesamewatchasIlost.這塊表與我丟的那塊一樣。(不是同一塊表)ThisisthesamewatchthatIlost.這就是我丟的那塊表。(是同一塊表)關系副詞when,where,why的用法以及與關系代詞的區分關系副詞在定語從句當中只能充當狀語，當從句能夠完整地表達一個意思時，用關系副詞引導定語從句。eg.Iwon’tforgetthedaywhenIgraduated.（從句完整）Istillrememberthedayswhenwestayedtogether?（從句完整）關系代詞在定語從句中充當句子成分，主語、賓語、表語、定語（whose）當從句結構不完整時，用關系代詞引導定語從句。關系副詞when,where和關系代詞that,which的區分Thisistheparkthatwevisitedlastyear.（定語從句中缺visit的賓語成分，用關系代詞）Thisistheparkwhereweheldabirthdayparty.（定語從句不缺成分，用關系副詞）關系副詞when,where,why和介詞+which之間的關系。關系副詞when,where,why可以用適當的介詞+which來替代。如：when=in/on/at…+which,where=in/on/at…+which,why=for+which。介詞的位置非常靈活，有時放在關系代詞之前，有時放在動詞之后。e.gIwon’tforgetthedatewhen(onwhich)Igotmarried.Thisisthecitywhere(inwhich)Ilived.=ThisistheroomwhichIlivedin.Idon’tknowthereasonwhy(forwhich)heisabsenttoday.當先行詞為point,situation,conditions,case,position,stage,scene,spot,activity,family,job等表示某人/物所處的情況、發展的階段或表達某事的某個方面時,用where引導定語從句,where相當于fromwhich,underwhich等,表示“在這種情況下”,“從……中”等。We’rejusttryingtoreachapointwherebothsideswillsitdowntogetherandtalk.我們只是盡力想能達到雙方共同坐下來商談的地步。思考：ThebookIhavechosenisFuLei’sFamilyLetters___________FuLeisharedhisviewsaboutartandlife.定語從句（二）課堂練習用適當的關系詞填空1.Thisistheonlybook_______Igotlastyear.2.Isthisthebookin_______youareinterested?3.Thisisthelargestanimal_______Tomsawinthezoo.4.Rosestillremembersthetreesandteachers______existinthemotherschool.5.Allthedesks_______areboughtlookreallywonderful.6.Doyouhaveanymoney_______isusedtobuildthefactory?7.Thisisthesecondwatch____myfatherboughtforme.8.Isthistheroom________youcleanedlasttime?9.Isthistheroom_________welivedbefore?10.Thisisthegarden_________theystayedforanight.11.Thisisthegarden_______theyvisitedlasttime.12.Tomhasforgottentheday_______helefthishome.13.Tomhasforgottentheday________Itoldhimlastday.14.Shestillrememberstheyear________shefoundherfirstjob.15.Shestillrememberstheyear________shespentinJining.家庭作業1.Whencompletelydevotedtothetask,________wasoftenthecase,hewouldtotallyforgetabouteatingorsleeping.Lucyisasmartgirl,_________eyesarebig.Youmaythinkofgivingupstudy,in_______casejustthinkitoverbeforemakingthedecision.Manyfactorsinfluenceastudentinhis/herstudy,mostof_________Ithinkareoutofateacher’scontrol.WewenttoMountainTailastweek,___________notsurprisingly,wascrowdedwithvisitors.Sallyisshowingusaroundthehouse,_________thewindowsarepaintedgreen._______isknowntous,thecompasswasfirstinventedinChina.Thenewly-builthouse,___________theroofisbrightred.Badlanguageisastage__________
