由关系副词及as引导的定从由关系副词及as引导的定从由关系副词及as引导的定从xxx公司由关系副词及as引导的定从文件编号：文件日期：修订次数：第1.0次更改批准审核制定方案设计，管理制度（二）由关系副词引导的定语从句1，关系副词有：________，_________及__________。eg:（1）,TherewasatimewhentherewerestillslavesinAmerica.=atwhichtherewerestillslavesinAmerica.（2）,IstillrememberthedaywhenIfirstwenttoBeijing.=____________IwenttoBeijing.（3）,Thisistheplacewhereheworks.=______________heworks.（4）,Thehousewherehelivedlastyearhasbeensoldout.=______________helivedlastyear.（5）,Thereareseveralreasonswhywecan’tdothat.=______________wecan’tdothat.★小结：（1），由关系副词引导定语从句时，先行词在从句中做_________，而不是主语，宾语或表语；（2），如果先行词是时间时，用_________引导从句；是地点时用_________引导从句；是reason时，用_________引导从句；（3），关系副词分别可以换成_________+which,具体介词由从句或先行词定。★特殊情况:1,如果先行词是time/day/morning/afternoon/evening/night/week/month/year等表时间的词时，关系副词when还可以用that代替，并可以省掉。eg:Westillrememberthesummer(when/that)wehadthebigflood.Hewillnotforgetthehappytime(when/that)weworkedtogether.2,以thereason为先行词的限定性定语从句通常由why\forwhich引导，也可以用that引导，还可以将其省掉。eg:Hedid’ttellmethereason(that)heleftsosoon.Thatisthereason（that）hecame.3,以theway为先行词的限定性定语从句通常由inwhich或that引导。这时，inwhich和that的作用相当于关系副词，也可以将其省掉。eg:Thisisthewayinwhich\thathedidit.Idon’tlikethewayinwhich\thathegetsalongwiththepeople.★关系副词和关系代词的选择：试比较以下例句：1，Iknowtheplacewherewecanswim.Iknowtheplacethatheistalkingabout.2，Iwillrememberthedaysthat\whichwespenttogether.Iwillrememberthedayswhenwespentourholidaystogether.3，Thisisthereasonwhy\forwhichhewaslate.Thisisthereasonthat\whichheexplainedtous.小结：用关系代词还是关系副词引导定语从句主要看关系词在从句中所起的作用。如果从句中的谓语是及物动词或不及物动词与介词构成，而其后又没有宾语，这时要由_______________引导定语从句。如果定语从句中的谓语动词是不及物动词，或从句中已经有了_________，_________或________等，也就是说从句中缺状语，要用________________引导定语从句。Dothefollowingexercises:1,Themuseum______heworksisinthesouthofthecity.Themuseum______wewenttoisinthesouthofthecity.2,Healwaysthinksoftheday______helefthishometown.Healwaysthinksoftheday______hespentwithhisfriends.3,Hegavemethereason______hedidn’tcometotheparty.Hegavemethereason______hetoldhisparents.（三）由as引导的定语从句：1，as引导的定语从句经常用于一下结构：asweknow,asis/wasknown/announced/reported/said,as的意义为“正如，就像”。as指代整个句子，并在句中做_________和________。eg:Asyouknow,Johnisawriter.Chinaisadevelopingcountry,asisknowntoall.Liuxiangdidn’ttakepartinthe29thOlympicGames,asisreported.2，先行词是such时，由as引导定语从句，并在从句中做________或________。eg:Ihaveneverheardsuchafunnystoryashetells.Heisnotsuchafoolashelooks.(区别：1,IhaveneverheardsuchafunnystorythatIlaughedalot.2,Heissuchafoolthathisclassmatesalllaughathim.)3，先行词由thesame修饰时，既可以由as引导定句，也可以由that引导定语从句,并在从句中做________或________。eg:SheworethesamedressthatsheworeatMary’swedding.Shewearsthesamedressashersisteriswearing.
