DefinitionReview:Whatisarestrictiveclause?structure?1.在复合句中,修饰某一_____或_____的从句叫定语从句。被修饰的名词或代词叫_______,定语从句一般放在先行词的_____,引导定语从句的词叫做_______。先行词后面关系词名词代词先行词关系词定语从句++关系代词关系副词?（which,who,whom…）（where,when,why）找出定语从句、关系词及关系词在从句中的充当的句子成分。1.Itwasatimewhenpeopleweredividedgeographically.2.EmperorQinshihuangunitedthesevenmajorstatesintooneunifiedcountrywheretheChinesewritingsystembegantodevelopinonedirection.3.Therearemanyreasonswhypeoplelearnaforeignlanguage.4.ThesewereanimalbonesandshellsonwhichsymbolswerecarvedbyancientChinesepeople.Step2.Presentation关系副词time时间状语placereason地点状语原因状语作状语，即从句成分齐全，不缺主，宾，表，定语。引导定语从句的关系副词包括when,where,why，一般代替先行词在从句中作状语，表示时间、地点、原因。Thetime

when

Iarrived.Themineswhere

Iworked.ThereasonwhyIgotajob.关系副词指代在从句中充当的成分例句whenwherewhyEg：Istillrememberthedayswhenweswamtogetherintheriver.总结关系副词的作用：指代表示时间、地点、原因的先行词连接主句和从句在从句中充当句子成分—状语先行词（表示时间）关系副词（作状语）定语从句关系副词如何区分关系代词和关系副词引导的定语从句：表示时间、地点及原因的名词作先行词时,关系词在定语从句中作状语时,用关系副词;若关系词在定语从句中作主语、宾语时,则用关系代词。方法：分析从句句子成分关系副词Eg:Theaccidenthasreachedtothepointboththeirparentsaretobecalledin.关系副词—

where特殊用法关系副词where还可用在表示抽象意义的地点名词后,如situation(情形),stage(阶段),point(地步),case(情况),position(位置),condition,activity,scene,occasion等,意思是“到了某种地步,在某种境况或情况中”。where重要提示并非所有的表示时间、地点、原因的先行词，后面的定语从句都用when和where引导。如果定语从句中缺少主语或宾语，就要用that或which引导。Thisisthehouse_____________myfatherbuiltlastyear.Doyoustillrememberthedays___________wespentinthecountryside?that/whichthat/which关系副词结论：先行词表时间、地点、原因关系词在从句中作状语判断先行词在从句中的成分，用正确的关系词填空。Thereason_______________hegaveuswasquitereasonable.Thisisthereason_______________hewent.Thisistheplace____________wevisitedlastyear.Thisistheplace____________heworks.Thatwasthetime____________hearrived.Doyoustillrememberthetime____________wespenttogether?which/thatwherewhenthat/whichwhy/forwhichthat/which?关系副词

定语从句三步解体法：一、划出定语从句；二、判断关系词在从句中做的成分———主宾表：关系代词；状：关系副词三、根据先行词确定关系词定语从句的引导词关系代词关系副词指人指物that(主语/宾语/表语),which(主语/宾语),who(主语/宾语),whom(宾语),whose(定语)，as(主语/宾语/表语)that(主语、宾语),which(主语、宾语),whose(定语)where(地点状语)when(时间状语)why(原因状语)Ps:关系词在从句中做状语时，连接词有时可以用介词+which/whom来替换关系副词Describeaday/time/place/reasonFillinthetabletocompleteeachphrasewitharestrictiverelativeclause.Thenusethephrasetomakecompletesentences.thedaywhentheplacewherethereasonwhythereasonin/atwhichWorkinpairs.AskandanswerthequestionsA:Whatkindofdaymakesyouhappy?A:What’syourfavouriteplaceatschool?A:Whatkindofteachersdoyoulikemost?A:Whodoyouadmiremost?Why?B:it’sadaywhen...B:It’s...,becauseitisaplacewhereB:Iliketeacherswho...B:Iadmire...That’sthereasonwhy二、“介词+关系代词”引导的定语从句关系副词when,where,why引导定语从句时,关系副词也可用“介词+关系代词”代替。1.

关系代词的确定在“介词+关系代词”引导的定语从句中,关系代词只能用which或whom，（先行词指物时,用which;先行词指人时,用whom）

介词+关系代词Heisthemaninwhomyoucanbelieve.(1)看介词与定语从句中动词或形容词的搭配。Hegavemesomebookswith

whichIamnotveryfamiliar.(2)看介词与先行词搭配。Thisisour

classroom

inwhichthereisateacher’sdesk.The

farm

onwhichmyfatherworksisfarfromthetown.(3)根据句子的意思而定。Thesoldier,withoutwhomIwouldn'thavesurvivedtheearthquake,retiredlastweek.2.

takecareof,lookforwardto,gothrough等。Thepatientafterwhomsheislookingisherfather.×特别提示：介词+关系代词1.Thefilmstar___________wetalkedalotyesterdaywillgiveusaspeechtomorrow.2.TheWestLake_________Hangzhouisfamousintheworldwillbemorebeautiful.3.Thesubject________XiaoWangisgoodisphysics.aboutwhomforwhichatwhich4.Thereason_________hecouldnotgotherewasthathisgradeswastoolow.5.Theprofessor__________Mr.Smithshookhandsyesterdayhasmadenewdiscoveriesinscience.6.Couldyoutellmetheday________youarrived?7.Iwilltreasurethedays________Ilivedhere.withwhomonwhichinwhichforwhich练一练Completethepassagewiththecorrectrelativeadverbsorpronouns.Addaprepositionwherenecessary.（P64）WhenIstartedstudyingGerman,itwasastruggle.Thewordsfeltstrangeonmytongue,andthegrammarwouldnotstayinmyhead.ItoldmymumthatIwantedtogiveup,andthatIwouldneverliveinacountry_______________Germanwasspoken.Mymumtoldmethatstudyingalanguagewasnotjustformyfuture.Itwasexerciseforthebrain;themoreIlearntofalanguage,themoremybrainwouldg
