關(guān)系副詞和“介詞+關(guān)系代詞”引導(dǎo)的限制性定語從句關(guān)系代詞as的用法1.引導(dǎo)限制性定語從句常和thesame,such,as等連用2.thesame...as...：指不同的人或物

thesame...that...：指相同的人或物3.常作主動語態(tài)的賓語，被動語態(tài)的主語Asweallknow/Asisknowntoall/Asweallcansee眾所周知Asisoftenthecase情況常常是這樣Asmightbeexpected正如所預(yù)料的那樣Ashasbeenpointedout正如所指出的那樣Ashasbeensaidbefore/above

正如前文所述As(it)oftenhappens

就像經(jīng)常發(fā)生的一樣4.可位于句首、句中、句尾，位置靈活5.可指代整個句子的內(nèi)容限制性定語從句和非限制性定語從句的區(qū)別1.作用不同限制性定語從句：在意義上與先行詞關(guān)系緊密，是不可缺少的定語，去掉之后意思不完整或失去意義非限制性定語從句：和主句的關(guān)系不十分密切，只是對先行詞作附加說明，去掉之后意思仍然清楚2.形式不同限制性定語從句中主句與從句間無逗號非限制性定語從句中主句與從句用逗號隔開3.先行詞限制性定語從句的先行詞只能是名詞或代詞非限制性定語從句的先行詞既可以是名詞或代詞，也可以是短語或句子4.關(guān)系詞不同that,why不能引導(dǎo)非限制性定語從句5.關(guān)系詞替代情況不同(1)限制性定語從句：whom作賓語時可用who替換非限制性定語從句：whom作賓語時不可用who替換介詞+whom=who(2)限制性定語從句：指人—that/who/whom非限制性定語從句：指人—who/whom6.關(guān)系代詞省略情況不同在限制性定語從句中，關(guān)系代詞作賓語時可省略(介詞后不可)在非限制性定語從句中，所有關(guān)系代詞不可省略Istillremembertheday.Imethimontheday.IstillrememberthedayonwhichImethim.whenThisistheclassroom.Westudyknowledgeintheclassroom.Thisistheclassroominwhichwestudyknowledge.where當(dāng)先行詞是表示抽象意義的地點(diǎn)名詞:occasion場合

case情況,事例condition條件,情況

situation情況,形勢stage階段,狀態(tài)

point地步

position位置且在定語從句中作地點(diǎn)狀語時，常用where/介詞+which引導(dǎo)定語從句Thisisthereason.Hefallsinlovewithherforthereason.Thisisthereasonforwhichhefallsinlovewithher.why介詞+關(guān)系代詞引導(dǎo)的定語從句1.關(guān)系代詞的使用先行詞指人時:介詞+whom先行詞指物時:介詞+whichThisisthestudentfor_____Iboughtabook.2.介詞的選用(1)根據(jù)定語從句中的謂語動詞與介詞的習(xí)慣搭配來確定Thisisthehistorybook____whichIpaid55yuan.(2)根據(jù)定語從句中的主要形容詞與介詞的習(xí)慣搭配來確定Hebroughttheresult____whichthebosswassatisfied.(3)根據(jù)先行詞與介詞的習(xí)慣搭配的來確定Doyoustillremembertheday__whichwemetforthefirsttime?(4)根據(jù)定語從句所表達(dá)的意思來確定Fortunatelywehadamap,____whichwewouldhavegotlost.有些固定動詞短語一般不能拆開(不及物動詞+介詞)，介詞仍放在動詞的后面如：lookat,lookafter,takecareofIsthisthebooksheislookingfor?關(guān)系代詞和關(guān)系副詞的選用方法依據(jù)根據(jù)從句的謂語動詞如果是及物動詞，后面若無賓語，用關(guān)系代詞如果是不及物動詞，用關(guān)系副詞根據(jù)先行詞在從句中所做的成分把先行詞放入定語從句中，若做主語或賓語、定語用關(guān)系代詞；做狀語則用關(guān)系副詞Thisisthefactory____heusedtowork.Thisisthefactory_____Ivisitedlastyear.Isthisthemuseum_____youvisitedafewdaysago?Isthisthemuseum____theexhibitionwasheld?when引導(dǎo)的狀語從句和定語從句的區(qū)別：1.when的譯法不同當(dāng)...時候/那時2.when的位置不同時間狀語從句中，when引導(dǎo)的從句可位于句首，也可以在主句之后；定語從句中when從句不能位于句首，且通常when前為表示時間的名詞3.when在從句的作用不同時間狀語從句中when是連詞，只起連接主句和從句的作用，不做從句的任何成分。但修飾主句的謂語，做主句的時間狀語1.Theplace____interestedmemostwastheChildren'sPalace.A.whichB.whereC.whatD.inwhich2.Doyouknowtheman_______?A.whomIspokeB.towhospokeC.IspoketoD.thatIspoke3.Thisisthehotel___lastmonth.A.whichtheystayedB.atthattheystayedC.wheretheystayedatD.wheretheystayed4.Doyouknowtheyear___theCommunistPartyofChinawasfounded?A.whichB.thatC.whenD.onwhich5.Thatistheday______I'llneverforget.A.whichB.onwhichC.inwhichD.when6.Thefactory______we'llvisitnextweekisnotfarfromhere.A.whereB.towhichC.whichD.inwhich7.Greatchangeshavetakenplacesincetheninthefactory_______weareworking.A.whereB.thatC.whichD.there8.Thisisoneofthebestfilms_______.A.thathavebeenshownthisyearB.thathaveshownC.thathasbeenshownthisyearD.thatyoutalked9.Canyoulendmethebook______theotherday?A.aboutwhichyoutalkedB.whichyoutalkedC.aboutthatyoutalkedD.thatyoutalked10.Thepen______heiswritingismine.A.withwhichB.inwhichC.onwhichD.bywhich11.Theyarrivedatafarmhouse,infrontof______satasmallboy.A.whomB.whoC.whichD.that12.Theengineer______myfatherworksisabout50yearsold.A.towhomB.onwhomC.withwhichD.withwhom13.Itthereanyoneinyourclass______familyisinthecountry?A.whoB.who'sC.whichD.whose14.I'minterestedin______youhavesaid.A.allthatB.allwhatC.thatD.which15.Iwanttousethesamedictionary______wasusedyesterday.A.whichB.whoC.whatD.as16.Heisn'tsuchaman______heusedtobe.A.whoB.whomC.thatD.as17.HeisgoodatEnglish,______weallknow.A.thatB.asC.whomD.what18.LiMing,______totheconcertenjoyeditverymuch.A.IwentwithB.withwhomIwentC.withwhoIwentD.Iwentwithhim19.Idon'tlike______asyouread.A.thenovelsB.thesuchnovelsC.suchnovelsD.samenovels20.Hetalkedalotaboutthingsandpersons________theyrememberedintheschool.A.whichB.thatC.whomD.what21.Theletterisfrommysister,______isworkinginBeijing.A.whichB.thatC.whomD.who22.Inourfactorythereare2,000workers,twothirdsof____arewomen.A.themB.whichC.whomD.who23.You'retheonlyperson______I'veevermet______coulddoit.A.who;/B./;whomC.whom;/D./;who24.Ilostabook,______Ican'tremembernow.A.whosetitleB.itstitleC.thetitleofitD.thetitleofthat25.LastsummerwevisitedtheWestLake,______Hangzhouisfamousintheworld.A.forwhichB.forthatC.inwhichD.what26.Ihaveboughtsuchawatch_______wasadvertisedonTV.A.thatB.whichC.asD.it27.Icanneverforgettheday_______weworkedtogetherandtheday______wespenttogether.A.when;whichB.which;whenC.what;thatD.onwhich;when28.Theway______helooksatproblemsiswrong.A.whichB.whoseC.whatD./29.Thisisthereason______hedidn'tcometothemeeting.A.inwhichB.withwhichC.thatD.forwhich30.Thismachine,______formanyyears,isstillworkingperfectly.A.afterwhichIhavelookedB.whichIhavelookedafterC.thatIhavelookedafterD.Ihavelookedafter31.Thereason______hedidn'tcomewas______hewasill.A.why;thatB.that;whyC.forthat;thatD.forwhich;what32.Heisworkinghard,______willmakehimpassthefinalexam.A.thatB.whichC.forwhichD.who33.Thatisnottheway______Idoit.A./B.whichC.forwhichD.withwhich34.Ihavetwogrammars,______areofgreatuse.A.allofwhichB.eitherofwhichC.bothofthatD.bothofwhich35.Iwanttousethesametools_______usedinyourfactoryafewdaysago.A.aswasB.whichwasC.aswereD.which36.Myneighboursusedtogivemeahandintimeoftrouble,_______wasverykindofthem.A.whoB.whichC.thatD.it37.Thisisthemagazine_______Icopiedtheparagraph.A.thatB.whichC.fromthatD.fromwhich38.Heisnotsuchaman_______wouldleavehisworkhalfdone.A.thatB.whichC.whoD.as39.Youcandependonwhateverpromise_______hemakes.A./B.whyC.whenD.whose40.Smoking,_______isabadhabit,is,however,popular.A.thatB.whichC.itD.though41.---Didyouasktheguard_______happened?---Yes,hetoldmeall_______heknew.A.what;thatB.what;whatC.which;whichD.that;that42.Ishallneverforgetthoseyears_______Ilivedonthefarmwiththefarmers,_______hasagreateffectonmylife.A.when;whoB.that;whichC.which;thatD.when;which43.Thenumberofthepeoplewho_______cars_______increasing.A.owns;areB.owns;isC.own;isD.own;are44.Duringthedays_____,heworkedasaservan
