B.mostofwhich

C.mostofwhat

D.mostofthatLead-in答案1.C。先行词aperiod表示“一个时期”，在定语从句中充当时间状语，用when或inwhich。2.D。先行词是thetopofMountQomolangma，“彩虹”应出现在它的上空，应用abovewhich引起非限制性定语从句。3.C。which指代整个主句内容，引导非限制性定语从句。4.C。先行词为manycities，在定语从句中表示“其中的”要用ofwhich。5.B。先行词为anumberoffactors，在定语从句中表示“其中的大多数”要用mostofwhich。Presentation1.介词+关系代词在定语从句中，关系代词前面一旦有介词，就不能用that和who了。此时就只能用whom（宾语），which（宾语）或whose（定语）了。Theteacher（who/that/whom）youspoketojustnowteachesusmaths.Theteachertowhomyouspokejustnowteachesusmaths.你刚才跟他（她）说话的老师教我们数学。PresentationThehouse（which/that）weoncelivedinhasbeenpulleddownforahospital.Thehouseinwhichweoncelivedhasbeenpulleddownforahospital.我原来住的房子由于建医院已经拆了。Thisismyfriend,whosefamilyI’mnowlivingwith.Thisismyfriend,withwhosefamilyI’mnowliving.这就是那位朋友，我和他（她）的家人住在一起。Presentation2.介词的位置当关系代词充当介词的宾语时，并不是所有的介词都能放到关系代词前面。一般有下面的规则：①与先行词搭配的介词一般放于关系代词前。Hebuiltatelescopethroughwhichhecouldstudythesky.他建造了一台望远镜，可以通过它研究太空。ThehousebesidewhichthereisabigtreeisLiHong’s.旁边有棵大树的那所房子是李红家。Presentation②与定语从句中的动词构成动词短语的介词可放于从句中，也可放于关系代词前。这样的短语有talkabout，speakto，livein，borrowfrom，lendto，waitfor等。在口语中，这样的介词一般放在定语从句中，位于动词后面，关系代词也可以省略；在书面语中，介词一般置于关系代词前面。That’sthelibrary（which/that）Ialwaysborrowbooksfrom.That’sthelibraryfromwhichIalwaysborrowbooks.那是我经常借书的图书馆。Presentation③像lookafter，lookfor，takecareof，comeacross，comeat，hearfrom，callon，longfor，runinto，meetwith，sendfor等这样的短语动词，介词和动词结合构成一个新的意义，不可拆分。所以，在定语从句中，短语动词中的介词不能前置。Thedoctor（who/whom/that）yousentforhasn’tcomeyet.你派人去请的医生还没有到。Thechance（which/that）wehavebeenlongingforhascomeatlast.我们盼望已久的机会终于来了。Theproblem（which/that）Imetwithyesterdayhasn’tbeensolvedyet.我昨天遇到的那个问题还没有解决。Spotlight1.TheheadteacherinwhoseclassLiHongstudiesisverystrictwiththem.李红所在班的班主任对他们要求严格。这个句型中，theheadteacher在定语从句中充当定语，用关系代词whose；介词in的前置，就出现了“介词+whose+名词”的结构。Thebossinwhoserestaurantmymotherworksisakindperson.我妈妈工作的那家饭店的老板是个好人。Themanagerwithwhosecompanyweoftendobusinesswaskilledinacaraccident.我们经常做生意的那家公司的经理在一次车祸中丧生了。SpotlightIsthatthetrainonwhichyouwenttoShanghailastyear?那就是你去年去上海乘坐的那趟列车吗？Theshipinwhichtheygobackhomehasn’tarrived.他们乘坐回家的船还没有到。2.

Myfatherhasboughtacarinwhichhegoestowork.我父亲买了辆车，他开着去上班。先行词为表示交通工具的名词时，不能用bywhich引导定语从句，而只能用in/onwhich。这是因为这些名词的前面都带有a，an，the，this，that，one’s等限定词。Practice1.Someexpertsthinkreadingisthefundamentalskillupon______schooleducationdepends.（2015安徽高考卷）it B.that C.whose D.which答案：D。先行词skill充当前置介词的宾语，只能用which。2.Hemaywinthecompetition,_____heislikelytogetintothenationalteam.（2013辽宁）A.inwhichcaseB.inthatcaseC.inwhatcaseD.inwhosecase答案：A。此处which指代前面主句，inwhichcase引导定语从句链接高考Practice3.Thechildren,______hadplayedthewholedaylong,werewornout.（2013浙江）A.allofwhatB.allofwhichC.allofthemD.allofwhom答案：D。定语从句中先行词为children，故答案为D。
