考点13定语从句考向一：定语从句的基本概念及其功能意义我们先看以下几个句子：（1）Thisishisbook.（2）Pleaseturnonthatgreenlight.（3）Doyoulikethebeautifulflowers?在这些句子中的book,light,flowers前面的修饰语只是简单词,它们对后面的几个名词起一种修饰作用。那如果要表达以下几个句子又该怎么办呢？（1）我昨天买的这本书不贵。（2）住在我隔壁的这个人是卖菜的。（3）那是他们去年住的房子。（4）小明还记得他第一次来广州那天。这时,我们会发现,只用简单词来做修饰语还不行，有的时候需要用句子来表达意思：(1):Thisbook(that/which)Iboughtyesterdayisnotexpensive.(2):Themanthat/wholivesnexttomesellsvegetables.(3):Thatisthehousewheretheylivedlastyear.(4):XiaomingstillremembersthedaywhenhefirstcametoGuangzhou.这些斜体部分的句子就是定语从句。我们把在复合句中修饰某一名词或代词的句子称之为定语从句。上面四句中的book,man,house,day是定语从句被修饰的词,叫作先行词，用来引导从句的that,which,who叫作关系代词（一般情况下，定语从句放在先行词后面），where,when叫作关系副词。考向二：定语从句的构成及类别关系代词That人，物主语宾语(1)Thehousethatwasbuiltin1987stayedupintheearthquake.(2)TheteacherthatteachesusisateacherofEnglish.Which物宾语主语(1)Theyplantedsometreeswhichdidn’tneedmuchwater.(which在从句中作主语)(2)Thefish(which)weboughtwerenotfresh.(which在从句中作宾语)Who人主语宾语ThemenwhovisitedourclassyesterdayisfromCanada.(who在从句中作主语)*Whom人宾语Theman(whom)youjusttalkedtoisMr.Li.(whom在从句中作宾语)Whose人，物定语(1)Iknowaboywhosemotherisateacherinourschool.(2)Helikethebookwhosecover(封面)isapicture.注：在whose后面，一定要有名词，因为它起到定语的作用，用来修饰名词。as人，物主语宾语ThisisasamepenasIlostyesterday.Heissuchapersonasisrespectedbyallofus.关系副词Where地点状语ThefactorywherehisfatherworksisIthewestofthecity.Why原因状语Thereasonwhyyouwerelatewasunbelievable.When时间状语IstillrememberthedaywhenIfirstcametoBeijing.【即学即练】1.Thefactory_____myfriendworksisfarfrommyhome.A.whenB.whereC.whichD.what2.Thefactory_____myfriendvisitedlastyearisfarfrommyhome.A.whenB.whereC.whichD.what3.Iwon’tforgettheday____Iwasborn.A.thatB.whenC.whichD.inwhich4.Iwon’tforgettheday____IspentinNanHuaTemplethreedaysagoA.thatB.whenC.whatD.onthat考向三：定语从句中几个须注意的问题（一）关于“介词+which/whom”结构我们还是先看几个句子：1.ThepersonwhomyoushouldwritetoisMr.Brown.2.Thathousethattheyarelivinginbelongstome.3.ThedaywhichmysisterwasbornonisMarch,1999.4.Sheshowedmethedictionarywhichshepaidalotmoneyfor.5.Themanwhomyouspoketolastnightismyfather.考虑一下，把上述五句的介词去掉可否？当然不行，因为句中的whom，that,which等在从句中无法做动词的宾语，那么就要在动词后加个合适的介词，句子才通。因此，这些句子也可说成：6.ThepersontowhomyoushouldwriteisMr.Brown.7.Thathouseinwhichtheyarelivingbelongstome.8.ThedayonwhichmysisterwasbornisMarch,1999.9.Sheshowedmethedictionaryforwhichshepaidalotmoney.10.Themantowhomyouspokelastnightismyfather.注意：1在第2句中的介词in如果要前置放到关系词前面，则不能写成：Thathouseinthattheyarelivingbelongstome.应该写成：Thathouseinwhichtheyarelivingbelongstome.2含有介词的短语动词一般不拆开，介词仍放在短语动词的后面。如：lookfor,lookafter,takecareof等。Thisisthewatch(which/that)Iamlookingfor.(正)ThisisthewatchforwhichIamlooking.(误)（二）关于“介词+whose+名词”结构首先我们来看两个句子。Thebosswenttothehospital.MrKingworkedintheboss’scompany.如果我们要把这两句话整合成一句话，该怎样做呢？可能同学们会想到以下的答...
