非谓语动词副词介词短语状语从句非谓语动词句子主干修饰角色演员Tips：从句起始标识:主从复合句主句从句＋起止标识：从引导词开始到句尾结束：IamateacherwhoteachesEnglish.到逗号结束：Asweallknow,theearthisround.到第二个谓语动词结束：Yaoming,whowasatopbasketballplayer,willcometoourschool.

到下一个引导词之前结束：ThisgiftwastheAmberRoom,whichwasgivenhisnamebecauseseveraltonsofamberwereusedtomakeit.三大从句引导词考查的判定口诀？〔从主从句的结构角度分析〕〔4种排列组合〕1.主句完整，从句不完整：2.主句完整，从句完整：定从关代that/which/who/whom/as/whose___________6个:定从关副___________when/where/why3个:

3.关系副词和介词+关系代词怎么互换？这里的关系代词只有which吗？whom?that呢?When=onwhich?Where=inwhich?Why=forwhich?ThinkingandDiscussion思考：

介词的选用有规律吗？是什么？三大原那么：一先：根据_____词与介词的搭配选择。二谓：根据_______句中谓语动词的搭配关系选择。三意义：根据先行词和定语从句中谓语动词共同的搭配关系或者说句子的意思来选择。〔语义决定语法〕

先行定语从从先行词下手.介词往往和先行词构成固定搭配.杀题背景：领先行词往往是那些表示时间、地点、原因、方法、工具等的词时,它们与介词之间有一定的固定联系,多用这种方法.〔比方时间常和on;in、by搭配,地点常用on;in;at,原因用for,方式用in;by;with等等〕【牛刀小试】1.Manypeoplewhohadseenthefilmwereafraidtogototheforestwhentheyrememberedthescenes______peoplewereeatenbythetiger.〔2005广东卷〕A.inwhichB.bywhichC.ofwhich

D.withthat2.TheEnglishplay______mystudentsactedattheNewYear’spartywasagreatsuccess.〔2004全国I〕A.forwhichB.atwhichC.inwhichD.onwhich一先：根据_____词与介词的搭配选择。二、杀题第二部曲————二动.即看从句中的谓语动词结构.根据从句中谓语动词的搭配选择适宜的介词.杀题背景：先行词没有明显可以固定搭配的介词,介词的选用与从句中谓语结构的搭配有关.eg:Americanwomenusuallyidentifytheirbestfriendassomeone____theycantalkfrequently.〔2004上海卷〕A.whoB.asC.aboutwhomD.withwhom三、第三部曲------通过判断主句表达的全部意义来确定适宜的介词.

eg:1.Hewaseducatedatthelocalhighschool,_______hewentontoBeijingUniversity.(2007江苏卷33题)A.afterwhichB.afterthatC.inwhichD.inthat2.TheEnglishplay______mystudentsactedattheNewYear’spartywasagreatsuccess.〔2004全国I〕A.forwhichB.atwhichC.inwhichD.onwhich四、特殊情况：介词of常用于结构：表示局部的词语＋of＋关系代词表示局部的词语常见的有：不定代词all,both,none,neither,either,some,any,数词(含基数词,序数词,分数和百分数)；数词+名词；the+最高级/比较级,以及表示数目或数量的词语many,most,few,several,enough,halfa,aquarter.高考考例：1.(2004湖北卷)Therearetwobuildings,________standsnearlyahundredfeethigh.A.thelargerB.thelargerofthemC.thelargeronethatD.thelargerofwhich2.(2004辽宁卷)Thefactoryproduceshalfamillionpairsofshoeseveryyear,80%_______aresoldabroad.A.ofwhichB.whichofC.ofthemD.ofthat五.不能用于“介词+关系代词的情况：

含有介词的固定的动词短语一般不拆开使用,如：lookfor,lookafter,takecareof等不能把介词提前.eg:Thisisthewatchwhich/thatIamlookingfor.1、关系副词引导的定语从句都可以改为介词+which的结构:

Doyourememberthedaywhenyoujoinedourclub?Thisisthehouse

whereIlivedtwoyearsago.Idon’tknowthereason

whyhesaidso.onwhichforwhichinwhichIdon’tliketheway

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

faceswest.2、关系代词whose+名词引导的定语从句可转化为the+名词+ofwhich/whom

或ofwhich/whom+the+名词结构。Thechildwassavedbyaman,whosenamewasnotknown.=Thechildwassavedbyaman,thenameofwhom/ofwhomthenamewasnotknown.句中的of表示所属关系哦

句中的of表示局部与整体的关系

高考常考句式1、数词+介词+关系代词(含基数词，序数词，分数和百分数〕Wehavethreeforeignteachers,twoofwhom/ofwhomtwoarefromCanada.2、代词+介词+关系代词〔如：all,both,none,neither,either,some,any等〕Theoldwomanhastwosons,bothofwhom/ofwhombothareteachers.3、形容词+介词+关系代词〔最高级/比较级〕Chinahasthousandsofislands,thelargestofwhich/ofwhichthelargestisTaiwanIsland.5、介词+关系代词+名词Hespentfouryearsincollege,duringwhichtimehestudiedmedicine.〔在那段时间内〕4、介词短语+关系代词Theyfinallyclimbedu
