非謂語動詞副詞介詞短語狀語從句非謂語動詞句子主干修飾角色演員Tips：從句起始標(biāo)識:主從復(fù)合句主句從句＋起止標(biāo)識：從引導(dǎo)詞開始到句尾結(jié)束：IamateacherwhoteachesEnglish.到逗號結(jié)束：Asweallknow,theearthisround.到第二個謂語動詞結(jié)束：Yaoming,whowasatopbasketballplayer,willcometoourschool.

到下一個引導(dǎo)詞之前結(jié)束：ThisgiftwastheAmberRoom,whichwasgivenhisnamebecauseseveraltonsofamberwereusedtomakeit.三大從句引導(dǎo)詞考查的判定口訣？〔從主從句的結(jié)構(gòu)角度分析〕〔4種排列組合〕1.主句完整，從句不完整：2.主句完整，從句完整：定從關(guān)代that/which/who/whom/as/whose___________6個:定從關(guān)副___________when/where/why3個:

3.關(guān)系副詞和介詞+關(guān)系代詞怎么互換？這里的關(guān)系代詞只有which嗎？whom?that呢?When=onwhich?Where=inwhich?Why=forwhich?ThinkingandDiscussion思考：

介詞的選用有規(guī)律嗎？是什么？三大原那么：一先：根據(jù)_____詞與介詞的搭配選擇。二謂：根據(jù)_______句中謂語動詞的搭配關(guān)系選擇。三意義：根據(jù)先行詞和定語從句中謂語動詞共同的搭配關(guān)系或者說句子的意思來選擇?！舱Z義決定語法〕

先行定語從從先行詞下手.介詞往往和先行詞構(gòu)成固定搭配.殺題背景：領(lǐng)先行詞往往是那些表示時間、地點、原因、方法、工具等的詞時,它們與介詞之間有一定的固定聯(lián)系,多用這種方法.〔比方時間常和on;in、by搭配,地點常用on;in;at,原因用for,方式用in;by;with等等〕【牛刀小試】1.Manypeoplewhohadseenthefilmwereafraidtogototheforestwhentheyrememberedthescenes______peoplewereeatenbythetiger.〔2005廣東卷〕A.inwhichB.bywhichC.ofwhich

D.withthat2.TheEnglishplay______mystudentsactedattheNewYear’spartywasagreatsuccess.〔2004全國I〕A.forwhichB.atwhichC.inwhichD.onwhich一先：根據(jù)_____詞與介詞的搭配選擇。二、殺題第二部曲————二動.即看從句中的謂語動詞結(jié)構(gòu).根據(jù)從句中謂語動詞的搭配選擇適宜的介詞.殺題背景：先行詞沒有明顯可以固定搭配的介詞,介詞的選用與從句中謂語結(jié)構(gòu)的搭配有關(guān).eg:Americanwomenusuallyidentifytheirbestfriendassomeone____theycantalkfrequently.〔2004上海卷〕A.whoB.asC.aboutwhomD.withwhom三、第三部曲------通過判斷主句表達(dá)的全部意義來確定適宜的介詞.

eg:1.Hewaseducatedatthelocalhighschool,_______hewentontoBeijingUniversity.(2007江蘇卷33題)A.afterwhichB.afterthatC.inwhichD.inthat2.TheEnglishplay______mystudentsactedattheNewYear’spartywasagreatsuccess.〔2004全國I〕A.forwhichB.atwhichC.inwhichD.onwhich四、特殊情況：介詞of常用于結(jié)構(gòu)：表示局部的詞語＋of＋關(guān)系代詞表示局部的詞語常見的有：不定代詞all,both,none,neither,either,some,any,數(shù)詞(含基數(shù)詞,序數(shù)詞,分?jǐn)?shù)和百分?jǐn)?shù))；數(shù)詞+名詞；the+最高級/比較級,以及表示數(shù)目或數(shù)量的詞語many,most,few,several,enough,halfa,aquarter.高考考例：1.(2004湖北卷)Therearetwobuildings,________standsnearlyahundredfeethigh.A.thelargerB.thelargerofthemC.thelargeronethatD.thelargerofwhich2.(2004遼寧卷)Thefactoryproduceshalfamillionpairsofshoeseveryyear,80%_______aresoldabroad.A.ofwhichB.whichofC.ofthemD.ofthat五.不能用于“介詞+關(guān)系代詞的情況：

含有介詞的固定的動詞短語一般不拆開使用,如：lookfor,lookafter,takecareof等不能把介詞提前.eg:Thisisthewatchwhich/thatIamlookingfor.1、關(guān)系副詞引導(dǎo)的定語從句都可以改為介詞+which的結(jié)構(gòu):

Doyourememberthedaywhenyoujoinedourclub?Thisisthehouse

whereIlivedtwoyearsago.Idon’tknowthereason

whyhesaidso.onwhichforwhichinwhichIdon’tliketheway

inwhich/thathetalks.特殊句式Helivesinaroom,whosewindowfaceswest.=Helivesinaroom,thewindowofwhich/ofwhichthewindow

faceswest.2、關(guān)系代詞whose+名詞引導(dǎo)的定語從句可轉(zhuǎn)化為the+名詞+ofwhich/whom

或ofwhich/whom+the+名詞結(jié)構(gòu)。Thechildwassavedbyaman,whosenamewasnotknown.=Thechildwassavedbyaman,thenameofwhom/ofwhomthenamewasnotknown.句中的of表示所屬關(guān)系哦

句中的of表示局部與整體的關(guān)系

高考?？季涫?、數(shù)詞+介詞+關(guān)系代詞(含基數(shù)詞，序數(shù)詞，分?jǐn)?shù)和百分?jǐn)?shù)〕Wehavethreeforeignteachers,twoofwhom/ofwhomtwoarefromCanada.2、代詞+介詞+關(guān)系代詞〔如：all,both,none,neither,either,some,any等〕Theoldwomanhastwosons,bothofwhom/ofwhombothareteachers.3、形容詞+介詞+關(guān)系代詞〔最高級/比較級〕Chinahasthousandsofislands,thelargestofwhich/ofwhichthelargestisTaiwanIsland.5、介詞+關(guān)系代詞+名詞Hespentfouryearsincollege,duringwhichtimehestudiedmedicine.〔在那段時間內(nèi)〕4、介詞短語+關(guān)系代詞Theyfinallyclimbedu
