whenIwasincollege.2.wewillneverforgettheday

whenweflewatanaltitudeof6000metersinthesky.1.when引导的定语从句当先行词为表示具体地点的名词(如：place,house,airport等)或抽象地点的名词(如：point,case,situation,stage,position,condition等)，且关系词在从句中作地点状语，定语从句用where引导。1.Thisisthehotel

相当于“in/at/on等+which”Thehousewhere(=inwhich)Marklivedisnowalibrary.3.why

相当于“for+which”Isthatthereasonwhy(=forwhich)shesuddenlychangedhermind?4.“介词+关系代词”引导的定语从句1.关系副词when，where，why引导定语从句时，也可用“介词+which”代替关系副词。1.ThisisthestudentforwhomIboughtabook.2.ThisistheshipbywhichIwenttoShanghai.2.在“介词+关系代词”引导的定语从句中，关系代词只能用which或whom,不可用that/who。先行词指物时用which，先行词指人时用whom。3.“名词，不定代词或数词+of+which(指物)/whom(指人)”在定语从句中作主语，说明整体中的一部分。1.Chinahaslotsofislands,oneofwhichisHainanIsland.2.Thebuildinghadbeenrepaired,theroofofwhichwasdestroyedagaininabigfire.3.MissLiuhasalotofstudents,someofwhomaregirls.(二)选用介词的依据1.根据先行词的搭配或从句中的动词、形容词等的搭配(即固定短语)。(1)YesterdaywevisitedtheWestLakefor

whichHangzhouisfamous.(2)Heisthestudentfromwhomweshouldlearn.(3)IrememberthedaysduringwhichIlivedhere.(4)Ican’tremembertheageatwhichhewontheprize.2.根据句子的意思来选择。(1)Thisisthepilotwithwhommybrotherhasworkedfortenyears.(2)Thisisthepilotbywhommysonwassaved.课堂小结（2'）关系副词用法注意：一些表示抽象地点的名词，如point，case，position，condition，situation等用where引导whenwherewhy指时间，在定语从句中充当时间状语指地点，在定语从句中作地点状语指原因，在定语从句中作原因状语当堂检测（15'）用恰当的关系代词，关系副词或“介词+关系代词”完成句子。1.Thedaysaregone_______physicalstrengthwasallyouneededtomakealiving.2.TheUSAisacountry______manydifferentdialectsarespoken.3.Thereason_______heexplainedatthemeetingsoundsreasonable.4.It’shelpfultoputchildreninasituation_____theycanseethemselvesdifferently.5.Isawahouse,thewindowsof______werebroken.6.Shehastwosons,bothof_____graduatedfromHarvardUniversity.7.—Doyouhaveanythingtosayforyourself?
