定语从句（二）介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时从句常由介词+关系代词引导(1)Theschool(that/which)heoncestudiedinisveryfamous.(2)Theschoolinwhichheoncestudiedisveryfamous.(3)TomorrowIwillbringhereamagazine(that/which)youaskedfor.(4)TomorrowIwillbringhereamagazineforwhichyouasked.(5)We’llgotohearthefamoussinger(whom/that/who)wehaveoftentalkedabout.(6)We’llgotohearthefamoussingeraboutwhomwehaveoftentalked.注意：1.含有介词的动词短语一般不拆开使用，如：lookfor,lookafter,takecareof等(1)Thisisthewatchwhich/thatIamlookingfor.(T＝正确)(2)ThisisthewatchforwhichIamlooking.(F＝错误)2.若介词放在关系代词前，关系代词指人时用whom，不可用who或者that；指物时用which，不能用that；关系代词是所有格时用whose(1)Themanwithwhomyoutalkedismyfriend.(T)(2)Themanwiththatyoutalkedismyfriend.(F)(3)TheplaneinwhichweflewtoCanadaisverycomfortable.(T)(4)TheplaneinthatweflewintoCanadaisverycomfortable.(F)3.“介词+关系代词”前可有some,any,none,both,all,neither,most,each,few等代词或者数词(1)Helovedhisparentsdeeply,bothofwhomareverykindtohim.(2)Inthebaskettherearequitemanyapples,someofwhichhavegonebad.(3)Therearefortystudentsinourclassinall,mostofwhomarefrombigcities.关系代词关系代词（一般情况下）that可用who,whom和which在从句做主语，谓语动词的宾语，但是不能做介词的宾语which指物，在从句中作主语，谓语或宾语；who在从句中作主语；whom在从句中宾语；where在从句中修饰表地点的名词，做地点状语；when在从句中通常修饰表时间的名词，做时间状语；why在从句中做原因状语，先行词通常是"reason"有时why也可用for+which代替。例：Adoctorisapersonwholooksafterpeople'shealth._______________________________先行词主语谓语宾语|________________________|定语从句修饰先行词关系副词引导的定语从句1.when指时间，在定语从句中做时间状语(1)IstillrememberthedaywhenIfirstcametotheschool.(2)Thetimewhenwegottogetherfinallycame.2.where指地点，在定语从句中做地点状语(1)ShanghaiisthecitywhereIwasborn.(2)ThehousewhereIlivedtenyearsagohasbeenpulleddown.3.why指原因，在定语从句中做原因状语(1)Pleasetellmethereasonwhyyoumissedtheplane.(2)Idon’tknowthereasonwhyhelooksunhappytoday.注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换(1)Thereasonwhy/forwhichherefusedtheinvitationisnotclear,(2)Fromtheyearwhen/inwhichhewasgoingtoschoolhebegantoknowwhathewantedwhenhegrewup.(3)Greatchangeshavetakenplaceinthecityinwhich./whereIwasborn.判断关系代词与关系副词方法一：用关系代词，还是关系副词完全取决于从句中的谓语动词。不及物动词后面无宾语，就必须要求用关系副词或者是介词加关系代词；而及物动词后接宾语，则要求用关系代词。例如：ThisisthemountainvillagewhereIstayedlastyear.I'llneverforgetthedayswhenIworkedtogetherwithyou.判断改错（注：先显示题，再显示答案，横线；用不同的颜色表示出。）（错）ThisisthemountainvillagewhereIvisitedlastyear.（错）IwillneverforgetthedayswhenIspentinthecountryside.（对）Thisisthemountainvillage(which)Ivisitedlastyear.（对）I'llneverforgetthedays(which)Ispentinthecountryside.习惯上总把表地点或时间的名词与关系副词where,when联系在一起。此两题错在关系词的误用上。方法二：准确判断先行词在定语从句中的成分(主、谓、宾、定、状)，也能正确选择出关系代词/关系副词。例1.Isthismuseum___youvisitedafewdaysago?A.whereB.thatC.onwhichD.theone例2.Isthisthemuseum____theexhibitionwasheld?A.whereB.thatC.onwhichD.theone答案：例1D，例2A例1变为肯定句：Thismuseumis___youvisitedafewdaysago.例2变为肯定句：Thisisthemuseum___theexhibitionwasheld.在句1...
