“介词+关系词”的用法1、关系代词在从句中作介词的宾语时,介词常可以提前,但介词提前时,关系代词只能用which或whom。如:Theschool(that/which)heoncestudiedinisveryfamous.→Theschoolinwhichheoncestudiedisveryfamous.TomorrowIwillbringhereamagazine(that/which)youaskedfor.→TomorrowIwillbringhereamagazineforwhichyouasked.We'llgotohearthefamoussinger(whom/that/who)wehaveoftentalkedabout.→We'llgotohearthefamoussingeraboutwhomwehaveoftentalked.2、关系副词when,where,why和介词+which之间的关系。关系副词when,where,why可以用适当的介词+which来替代。介词的位置非常灵活,有时放在关系代词之前,有时放在动词之后。如:when=in/on/at…+which,where=in/on/at…+which,why=for+which如:Iwon’tforgetthedatewhen(onwhich)Iwasborn.Thisistheroomwhere(inwhich)Ilived.=ThisistheroomwhichIlivedin.Idon’tknowthereasonwhy(forwhich)hehasn’tcometoday.Tomstillremembersthedayswhen(inwhich)theylivedinTianjin.注意:1).含有介词的动词短语一般不拆开使用,如:lookfor,lookafter,takecareof等如:Thisisthewatchwhich/thatIamlookingfor.(√)ThisisthewatchforwhichIamlooking.(F)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如:Themanwithwhomyoutalkedismyfriend.(√)Themanwho/thatyoutalkedwithismyfriend.(F)TheplaneinwhichweflewtoCanadaisverycomfortable.(√)TheplaneinthatweflewintoCanadaisverycomfortable.(F)3).“介词+关系代词”前可有some,any,none,both,all,neither,most,each,few等代词或者数词如:Helovedhisparentsdeeply,bothofwhomareverykindtohim.Inthebaskettherearequitemanyapples,someofwhichhavegonebad.Therearefortystudentsinourclassinall,mostofwhomarefrombigcities.4).把握“介词+关系代词”结构中介词的选用介词的选择与主句中先行词的搭配密切相关。如:That”sthereasonforwhichhewaslateforschool.ThisisthebookonwhichIspent8Yuan.介词选择的三大规则:1.取决于从句中的谓语动词同介词的搭配。(V+pre.)如:HeisthemanwhomItalkedwiththismorning.2.取决于先行词同介词的常规搭配。四组常考的搭配:1)extentdegree(程度)同to搭配2)price(具体多少钱时与at;若指价格方面与in搭配)speedrate同at搭配3)fieldareaaspectsphere(领域,方面)同in搭配例句:ThefieldinwhichIstudiedinuniversityispsychology.4)basisgroundfoundation(基础)同on搭配
