定语从句专项练习.ppt

概念:1.在句子中修饰名词或代词,定语从句在句中充当定语.2.定语从句必须有先行词,并尽量靠近先行词.3.在定语从句中,关系词在从句中充当成分.关系代词与关系副词关系代词:指人:指物:指人或物:关系副词:who(主格),whom(宾格),whose(所有格)which(主格,宾格),whose(所有格)thatwhen,where,why注意:先行词有下列情况或附有下列修饰语时,通常用关系代词that。1)先行词是all,no,none,everyone,something,much,little等；2)先行词前有序数词(thefirst…),形容词最高级(thebest…),thelast,thesame,theonly等；3)如果先行词中既含有表示人的名词又有表示物的名词时；4)若主句中有疑问代词who或者which，为了避免重复,关系代词不要再用who,which，而用that。1.Thisisall____Iknowaboutthematter.A.thatB.whatC.whoD.whether2.Isthereanythingelse_____yourequire?A.whichB.thatC.whoD.what3.Thelastplace_____wevisitedwastheGreatWall.A.whichB.thatC.whereD.it4.Hetalkedhappilyaboutthemenandbooks_____interestedhimgreatlyintheschool.A.whichB.thatC.itD.whom5.Thereisnodictionary_____youcanfindeverything.A.thatB.whichC.whereD.inthat6.Thisisoneofthebestbooks_______.A.thathaveeverbeenwrittenB.thathaseverbeenwrittenC.thathaswrittenD.thathavewritten7.Isoxygentheonlygas_____helpsfireburn?A.thatB./C.whichD.it提醒:介词﹢关系代词引导的定语从句,关键是判断介词的选择,方法一是看从句谓语部分缺少什么介词(习惯搭配),再则可以通过整个句子整体含义来判断,结合生活实际来判断.例：TheSecondWorldWar_____millionsofpeoplewerekilledin1945.A.duringwhichB.inthatC.whereD.onwhich1.Doyouknowwholivesinthebuilding______thereisawell?A.infrontofitB.infrontofwhoseC.infrontofwhichD.infrontwhich2.I’llneverforgettheday____IjoinedtheLeague.A.onwhichB.inwhichC.whichD.atwhich3.Jeanwasheroldfriend,____sheborrowedanecklace.A.fromwhoB.fromwhomC.tothatD.towhom5.Hisglasses,_____hewaslikeablindman,felltothegroundandbrokeitsleg.A.whichB.withwhichC.withoutwhichD.that6.Doyouknowthereason____hewaslate?A.thatB.whichC.forwhatD.forwhich7.Ihaveboughttwoballpens,____writeswell.A.noneofwhichB.neitherofwhichC.noneofthemD.neitherofthem提示:as,which均可以引出非限制性定语从句,如都指前一句话,二者可以互换。as引导的从句可以放在句首,as本身有“正如…..正象…”之意，与之连用的词有know,see,expect,announce,pointout等。此外,在thesame…as…；such…as...中as引导的是限制性定语从句.例：Theearthisround,_____weallknow.A.thatB.whichC.whoD.asHewentabroad,as/whichwasexpected.Hewentabroad,whichwasunexpected.1.______wasnatural,hemarriedJenny.A.WhichB.ThatC.ThisD.As2.Suchsigns_____weuseintheexperiment______Greekletters.A.as,areB.as,isC.that,areD.that,is3.Ipassedhimalargeglassofwhisky,_____hedrankimmediately.A.thatB.asC.whichD.who4.Sheisverygoodatdance,____everybodyknows.A.thatB.whichC.whoD.as5.Itwasraining,_____wasapity.A.whatB.thatC.thewhichD.which6.______hasbeensaidabove,grammarisasetofdeadrules.A.WhichB.WhatC.ThatD.As7.Wedothesamework_____theydo.A.whichB.asC.thanD.likeTHANKYOU!Jennifer
