whomwearefamiliar.当先行词是表人的名词或代词时，介词后的关系代词用whom，不能用who。1.Thecity

inwhichshelivesisfaraway.2.TheEnglishplayin

whichmystudentsactedattheNewYear’spartywasagreatsuccess.当先行词是表事物的名词或代词时，介词后的关系代词要用which，不能用that。在“介词+关系代词”结构中，如何准确地选择介词呢？This

the

story.由于句意含有“从……”的意思，所以用介词

from。from确定介词原则一：根据主从句之间的意思确定所需介词。Thisroadwilltakemetotheplace____whichIbelong.根据大意，从句意为“我属于的地方”。根据短语“belongto”可知空格处应填to。to确定介词原则二：根据从句动词、形容词等构成的短语确定所需介词。Jackistheveryperson_______Iwillturnwhenintrouble.据题干大意，从句意为“我遇到困难可以求助的人”。“求助”即“turnto”，又因先行词指人，故答案为

“towhom”。towhomThesongoftentakesmebacktothedaywhentheaccidenthappened.Thesongoftentakesmebacktotheday_____whichtheaccidenthappened.据第一句可知，第二句中which用来指先行词“theday”，在从句中意为“在这天”，故填介词“on”。确定介词原则三：根据先行词确定所需介词。on此时“介词+关系代词”结构往往可以和关系副词互换。如：

when=表时间的介词(in,at,during等)+whichwhere=表地点的介词(in,at,on,under等)

+which;why=表原因的介词for+which1.Imetthechild(whom)Ilookedaftertenyearsago.我遇到了十年前我照料过的那个孩子。2.Thisisthepen(that/which)youarelookingfor.这是你正在找的钢笔。含有介词的动词固定短语在定语从句中一般不拆开，在这种情况下，介词仍然放在后面，如hearfrom，lookafter，lookfor等。而在介词处于句尾时，句中的关系代词可以省略。注意：Exercise1.Istillremembertheday___Icamehere.A.onwhichB.thatC.whenD.atwhich2.Thisisthehouse____Ilivedlastyear.A.thatB.whereB.inwhichD.atwhich多选。Themorninginwhichmydoggotlostwasinmymindforever.改错。解析：在具体某天的早上、下午等时刻前的介词应用on，即onthemorning.onConnectthesentenceswithapreposition+whom/which.21.TheZhuangisanethnicgroup.ItspopulationisthelargestofallethnicgroupsinChina.2.Guangxiisaprovince.TheLongjiRiceTerracesarelocatedinit.TheZhuangisanethnicgroupofwhichthepopulationisthelargestofallethnicgroupsinChina.GuangxiisaprovinceinwhichtheLongjiRiceTerracesarelocated.ExerciseP653.Iwanttovisitthisculturallandscape.ThetitleofUNESCOWorldHeritageSitewasgiventoitin2016.4.Heisanexpertonriceplanting.ThelocalZhuangpeoplehavelearntalotfromhim.IwanttovisitthisculturallandscapetowhichthetitleofUNESCOWorldHeritageSitewasgivenin2016.HeisanexpertonriceplantingfromwhomthelocalZhuangpeoplehavelearntalot.P65Completethepassagewithapreposition+whom/which.3fromwhichinwhichforwhichforwhomP65“介词+关系代词”引导的定语从句介词的确定：1.由主从句的句意决定；2.由从句动词、形容词等构成的固定短语确定；3.根据先行词确定所需介词。结构：介词+which(指物)/介词+whom(指人)实战高考Helikesthathecansitandcheckhisphoneinpeaceorchatupthebarkeeper___________he’sonafirst-namebasisifhewantstohavealittleinteraction.[2019课标全国卷Ⅰ阅读理解C篇]withwhom他喜欢能坐着安静地看手机，或者如果他想和别人有点交流的话，就和他能直呼其名的服务生聊上几句。1.根据句意填空。实战高考2.Someexpertsthinkreadingisthefundamentalskillupon______schooleducationdepends.[2015安徽]3.Creatinganatmosphere_______employeesfeelpartofateamisabigchallenge.[2015·浙江]A. as     B. whose         C. inwhich     D. atwhich which1.Doyoulikethebook___________shelearnedalot?2.Thetower___________peoplecanhaveagood
