where引导的从句PPT课件

.,1,Where引导的从句,一.Where引导定语从句a.Where引导的定语从句修饰表示地点的名词，如place,room,house,street,area等，并在定语从句中作地点状语。Where在定语从句中用作关系副词，作状语，先行词一般指地点。某些在从句中充当地点状语的“介词+关系词”结构可以与where互换地点：Where=at/in/on+which1)ThisisthehouseinwhichIlivedtwoyearsago=ThisisthehousewhereIlivedtwoyearsago.2)StephenHawkingbelievesthattheearthisunlikelytobetheonlyplanetwherelifehasdevelopedgradually.(Where=onwhich),.,2,比较学习1)Thisisthefactorywhere/inwhichyouworkedlastyear.2)Thisisthefactorythat/whichyouvisitedlastyear.在第一句中，关系词在定语从句中作状语，所以用关系副词where或者inwhich,因为定语从句中worked是个不及物动词；而在第二句中，关系词在定语从句中做宾语，因此用that或which，还可以省略，visited是个及物动词。,.,3,b.Where引导的定语从句修饰抽象的，模糊的地点，如situation,stage,point,case,activity等。1)修饰抽象名词situationa)Hesgothimselfintoadangeroussituationwhereheislikelytolosecontrolovertheplane.b)Hegotintoasituationwhereitishardtodecidewhatisrightandwrong.2)修饰抽象名词activityThosesuccessfuldeafdancersthinkdancingisanactivitywheresightmattersmorethanhearing.3)修饰抽象名词pointAftergraduationshereachedapointinhercareerwheresheneededtodecidewhattodo.,.,4,4)修饰抽象名词caseTherearecaseswheretheword“mighty”isusedasanadverb.5)修饰抽象名词positionItsputmeinapositionwhereIcantaffordtotakethejob.6)修饰抽象名词job等Shewantsajobwherehermanagementskillscanbeputtogooduse.7)Lifeisalongracewherewecompetewithotherstogobeyondourselves.8)Inexperimentswhereyoungteensareallowedtosleepaslongastheywant,theytendtosleepanaverageof9hours.,.,5,c.当然，我们碰到这些词作为先行词时并不一定都用where,我们也要具体情况具体分析，他们只有在定语从句中作状语时候才用where.1)Wearetryingtoreachapointwherebothsideswillsitdowntogetherandtalk.2)Doyouhaveanythingtosayforyourself?Yes,theresonepoint(that/which/-)wemustinsiston.第一个句子中关系词在定语从句中作状语，所以选择关系副词where。第二个句子中关系词在定语从句中做宾语，所以选择关系代词that,which或者不填。3)ItwasinthehotelwhereIlivedthatIlastsawMr.Smith.（定语从句+强调句的结合）4)Theplacewherethebridgeissupposedtobebuiltshouldbewherethecross-rivertrafficistheheaviest.(where引导的定语从句和表语从句结合),.,6,二.Where还可以引导名词性从句(宾语从句，表语从句，主语从句，同位语从句)a.Where引导的名词性从句，where意思接近theplacewhere,b.可译为“的地方”，where是疑问副词。c.Where引导名词性从句（主语从句，宾语从句，表语从句，同位语从句）where在从句中充当地点状语1)Whereweshouldgocampinghasntbeendecided.主语从句2)Thatswherewediffer.表语从句3)Wehaventyetsettledthequestionwherewearegoingtospendoursummervacation.(同位语从句),.,7,4)Ihavenoideawheretheyarespendingtheirholidays.同位语从句(同位语从句和所修饰的名词在内容上为同一关系，对其内容作进一步说明)5)Nomatterwhereyougo,Illwaitforyouhere.(让步状语从句)6)Shewasfreetogotowhereshelikedanddowhatsheliked.宾语从句7)ThedriveraskedmewhereIwantedtogo8)Thefirstthingistofindoutwheresheis.,.,8,三.Where引导状语从句a.Where前没有表示地点的先行词。b.Where是从属连词c.Where引导的从句修饰主句的谓语动词。d.Where引导地点状语从句意思接近in/attheplacewhere可译为“在的地方”1)Thefamousscientistgrewupwherehewasbornandin1930hecametoShanghai.2)Shefoundherpassportwhereshelostit.3)Putthemedicinewherechild
