关系副词和“介词+关系代词”引导的限制性定语从句关系代词as的用法1.引导限制性定语从句常和thesame,such,as等连用2.thesame...as...：指不同的人或物

thesame...that...：指相同的人或物3.常作主动语态的宾语，被动语态的主语Asweallknow/Asisknowntoall/Asweallcansee众所周知Asisoftenthecase情况常常是这样Asmightbeexpected正如所预料的那样Ashasbeenpointedout正如所指出的那样Ashasbeensaidbefore/above

正如前文所述As(it)oftenhappens

就像经常发生的一样4.可位于句首、句中、句尾，位置灵活5.可指代整个句子的内容限制性定语从句和非限制性定语从句的区别1.作用不同限制性定语从句：在意义上与先行词关系紧密，是不可缺少的定语，去掉之后意思不完整或失去意义非限制性定语从句：和主句的关系不十分密切，只是对先行词作附加说明，去掉之后意思仍然清楚2.形式不同限制性定语从句中主句与从句间无逗号非限制性定语从句中主句与从句用逗号隔开3.先行词限制性定语从句的先行词只能是名词或代词非限制性定语从句的先行词既可以是名词或代词，也可以是短语或句子4.关系词不同that,why不能引导非限制性定语从句5.关系词替代情况不同(1)限制性定语从句：whom作宾语时可用who替换非限制性定语从句：whom作宾语时不可用who替换介词+whom=who(2)限制性定语从句：指人—that/who/whom非限制性定语从句：指人—who/whom6.关系代词省略情况不同在限制性定语从句中，关系代词作宾语时可省略(介词后不可)在非限制性定语从句中，所有关系代词不可省略Istillremembertheday.Imethimontheday.IstillrememberthedayonwhichImethim.whenThisistheclassroom.Westudyknowledgeintheclassroom.Thisistheclassroominwhichwestudyknowledge.where当先行词是表示抽象意义的地点名词:occasion场合

case情况,事例condition条件,情况

situation情况,形势stage阶段,状态

point地步

position位置且在定语从句中作地点状语时，常用where/介词+which引导定语从句Thisisthereason.Hefallsinlovewithherforthereason.Thisisthereasonforwhichhefallsinlovewithher.why介词+关系代词引导的定语从句1.关系代词的使用先行词指人时:介词+whom先行词指物时:介词+whichThisisthestudentfor_____Iboughtabook.2.介词的选用(1)根据定语从句中的谓语动词与介词的习惯搭配来确定Thisisthehistorybook____whichIpaid55yuan.(2)根据定语从句中的主要形容词与介词的习惯搭配来确定Hebroughttheresult____whichthebosswassatisfied.(3)根据先行词与介词的习惯搭配的来确定Doyoustillremembertheday__whichwemetforthefirsttime?(4)根据定语从句所表达的意思来确定Fortunatelywehadamap,____whichwewouldhavegotlost.有些固定动词短语一般不能拆开(不及物动词+介词)，介词仍放在动词的后面如：lookat,lookafter,takecareofIsthisthebooksheislookingfor?关系代词和关系副词的选用方法依据根据从句的谓语动词如果是及物动词，后面若无宾语，用关系代词如果是不及物动词，用关系副词根据先行词在从句中所做的成分把先行词放入定语从句中，若做主语或宾语、定语用关系代词；做状语则用关系副词Thisisthefactory____heusedtowork.Thisisthefactory_____Ivisitedlastyear.Isthisthemuseum_____youvisitedafewdaysago?Isthisthemuseum____theexhibitionwasheld?when引导的状语从句和定语从句的区别：1.when的译法不同当...时候/那时2.when的位置不同时间状语从句中，when引导的从句可位于句首，也可以在主句之后；定语从句中when从句不能位于句首，且通常when前为表示时间的名词3.when在从句的作用不同时间状语从句中when是连词，只起连接主句和从句的作用，不做从句的任何成分。但修饰主句的谓语，做主句的时间状语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
