when-where-why引导的定语从句

when，where，why引导的定语从句when，where，why作为定语从句的引导词，总称为关系副词。下面用句子合并的方法分析它们的使用。一、where引导的定语从句请分析下面两个简单句：句①Iknowagarden.句②Youcanfindwildstrawberriesthere.把句②变为句①的定语从句，句①中的agarden做定语从句的先行词。在句②中there指句①中提到的agarden也就是定语从句的先行词，there在句中做地点状语，因此要用where引导定语从句，代替句②中的there，也就是说there就不能出现在定语从句中了。由此得到句③Iknowagardenwhereyoucanfindwildstrawberries.句②还可以写作句④Youcanfindwildstrawberriesinit(it指句①中的garden，“在花园中”要使用介词短语inthegarden)。把句④变为句①的定语从句，因为it做介词in的宾语，先行词是agarden，指物。在这种定语从句中介词常常提到定语从句的开始，这时关系代词只能使用which替代it，it就不能在定语从句中出现了。由此得到句⑤即：Iknowagardeninwhichyoucanfindwildstrawberries.请把下面每组的两句话合并为一句，把第二句话变为第一句的定语从句。第一组：Thisisthevillage.Iwasbornthere.→ThisisthevillagewhereIwasborn.第二组：Thelabisnotfarfromhere.Thechemistoftendoesexperimentsthere.→Thelabwherethechemistoftendoesexperimentsisnotfarfromhere.二、when引导的定语从句请分析下面两个简单句：句①Weshallrememberthedays.句②Westudiedtogetherthen.把句②变为句①的定语从句，句①中的thedays做定语从句的先行词。在句②中then指句①中提到的thedays，也就是定语从句的先行词，then在句中做时间状语，因此要用when引导定语从句，代替句②中的then，也就是说then就不能出现在定语从句中了。由此得到句③Weshallrememberthedayswhenwestudiedtogether.句②还可以写作句④Westudiedtogetherduringthedays.(介词短语duringthedays含义为“在这些日子里”)。把句④变为句①的定语从句，因为thedays做介词during的宾语，先行词是thedays，指物，在定语从句中介词during提前，用关系代词which替代thedays，thedays就不能在定语从句中出现了。由此得到句⑤Weshallrememberthedaysduringwhichwestudiestogether.请把下面每组的两句话合并为一句，把第二句话变为第一句的定语从句。第一组：I'vealwayslongedforthedays.Ishouldbeabletobeindependentthen.→I'vealwayslongedforthedayswhenIshouldbeabletobeindependent.第二组：Therearemoments.Iforgetallaboutitthen.→TherearemomentswhenIforgetallaboutit.三、why引导的定语从句请分析下面两个简单句：句①Hewantedtoknowthereason.句②Iwaslateforthereason.把句②变为句①的定语从句，句①中的thereasons做定语从句的先行词。因为thereason做介词for的宾语，先行词是thereason指物，在定语从句中介词for提前，用关系代词which替代thereason，thereason就不能在定语从句中出现了。由此得到句③HewantedtoknowthereasonforwhichIwaslate.注意：在定语从句中当先行词为thereason(s)，定语从句由forwhich引导时，可以用why代替forwhich。由此我们得到句⑤HewantedtoknowthereasonwhyIwaslate.请把下面两句话合并为一句，把第二句话变为第一句的定语从句。Thereasonisnotveryconvincing.Hecameforthereason.→Thereasonwhyhecameisnotveryconvincing.Thereasonforwhichhecameisnotveryconvincing.■巩固性练习一、合并句子请把下面每组的两句话合并为一句，把第二句话变为第一句的定语从句。1.Therecameaday.Therainfellatlastthen.2.Thisisthehour.Theplaceisalwaysfullofwomenandchildrenthen.3.Wewillstartatthepoint.Weleftoffthere.4.Givemeonegoodreason.Ishouldhelpyouforthereason.5.Thisisthefactory.Hisfatherworksthere.6.Idon'tknowthereason.Youquarreledwithhim.7.I'llneverforgetthedays.Westudiedtogetherthen.二、链接高考1.All___isneededisasupplyofoil.A.thethingB.thatC.whatD.which2.Finally，thethiefhandedeverything___hehadstolentothepolice.A.whichB.whatC.whateverD.that3.InfacttheSwededidnotunderstandthethreequestions____wereaskedinFrench.A.whereB.whoC.inwhichD.which4.Canyoutellmethenameofthefactory___youvisitedlastweek？A.whatB.whereC./D.when5.Hisparentswouldn'tlethimmarryanyone___familywaspoor.A.ofwhomB.whomC.ofwhoseD.whose6.AfterlivinginParisfor50yearshereturnedtothesmalltown____hegrewupasachild.A.whichB.thatC.whereD.when7.Thefilmbroughtthehoursbacktome____Iwastakengoodcareofinthatfar-awayvillage.A.untilB.thatC.whenD.where参考答案一、合并句子1.Therecameadaywhentherainfellatlast.2.Thisisthehourwhentheplaceisalwaysfullofwomenandchildren.3.Wewillstartatthepointwhereweleftoff.4.GivemeonegoodreasonwhyIshouldhelpyou.5.Thisisthefactorywherehisfatherworks.6.Idon'tknowthereasonwhyyouquarreledwithhim7.I'llneverforgetthedayswhenwestudiedtogether.二、高考答案：1-5BDDCD6-7CC
