LearningobjectivesAExploringtherules引导限制性定语从句的关系副词有when、where和why，它们在从句中分别作时间状语、地点状语和原因状语，修饰从句谓语动词。关系副词when、where和why可以用“介词+which”来代替。由关系副词引导的限制性定语从句讲解一、关系副词when的用法1.

在关系副词when引导的定语从句中，先行词往往是day、week、time、year、month、morning等表示时间的名词。如：AprilFool’sDayisaspecialdaywhenyoucanplayajokeonsomeone.IcanstillrememberthesunnymorningwhenIarrivedoncampus.2.

从句中缺少时间状语，且先行词为stay、visit、occasion等一些

抽象的具有模糊时间概念的名词时，定语从句需要用关系副

词when来引导。如：ThesepresentscanremindmeofmystayinOxfordwhenImademanyfriendssharingthesameinterest.Alectureisanoccasionwhenwecanlearnandbenefitalot.讲解3.

先行词是表示时间的名词时，并非一定要用when引导定语从

句。若定语从句中缺少主语、表语或宾语等，则用that/which

引导。试比较：Iwillneverforgetthedaywhenwefirstmetinthemountainvillage.Iwillneverforgetthedaythat/whichwespenttogetherinthatmountainvillage.注意讲解二、关系副词where的用法1.

在关系副词where引导的定语从句中，先行词通常是place、

room、factory等表示地点的名词。如：Theschoolgateistheplacewherewewillmeeteachothertomorrowmorning.Thisisthecavewherewecameacrossthebearthatday.2.

从句中缺少地点状语，且先行词为situation、point、case、

condition、stage等一些含有抽象地点意义的名词时，定语从句

要用关系副词where来引导。如：Wefoundourselvesinasituationwherewehadtomakeadecisionimmediately.IgottothestagewhereIlostallinterestintheidea.讲解3.

先行词是表示地点的名词时，并非一定要用where引导定从句。

若定语从句中缺少主语、表语或宾语等，则用that/which引导。

试比较：NanjingisthecitywhereIgrowup.Nanjingisthecity(that/which)Iwanttovisitmost.注意讲解三、关系副词why的用法1.

在关系副词why引导的定语从句中，先行词一般是reason等

表示原因的名词。如：Thereasonwhybatshaveauniqueimmunesystemisthattheirbodytemperatureishigherthananyothermammal.2.

先行词是reason时，并非一定要用why引导定语从句。若定

语从句中缺少主语、表语或宾语等，则用that/which引导。如：Thereasonwhythepresidentwenttothevillagewastouching.Thereasonthatthepresidentmentionedattheconferencewastouching.注意即学即练I’llneverforgetthemuseum___________wevisitedtogether.I’llneverforgetthemuseum___________thepaintingsaresoappealing.Wearelivinginanage____________isseeinggreatchanges.Wearelivinginanage____________manythingsaredoneoncomputer.Thereason____________hegaveusisnottrue.Thereason____________hedidn’tcometoschoolisnottrue.(which/that)wherewhich/thatwhenwhy(which/that)Belowisapartofamagazinearticleaboutsleepproblems.Findthesentenceswithrestrictiverelativeclausesinthearticleandfillintheboxbelow.Thefirstonehasbeendoneforyou.Doyourememberatimewhenyouhadnoworriesstoppingyoufromgettingagoodnight’srest?Oneofthereasonswhypeoplefailtogetagoodnight’ssleepispressurefromschoolorwork.Theyarestillgrowing,and
