夯实基础

(如何判断定语从句并选用适当的关系词)例1：Thisisthehouse____________wasbuiltbymygrandfather.一找先行词：一般是从句前面的名词或代词，此处为thehouse；二定其成分：(thehousewasbuiltbymygrandater)：

把先行词代入从句中,此处thehouse作主语；三选关系词:先行词指物时用that或which，且不能省略例2：Thisisthehouse_________mygrandfatherlived.一找先行词thehouse,二定为地点状语(mygrandfatherlivedinthehouse(补介词)，三选用where(先行词在从句中作地点状语时，关系词常用where)。that/whichwhereThereason

重点突破1-1(如何选用适当的介词)一、关系副词引导的定语从句，可以用“介词+which/whom”替换。1.Istillrememberthedays

when

welaughedandhadfunwithoutanyworries.分析：welaughtedand....worriesin/duringthedays.考点：“在某些日子里，要用介词in/during。2.Istillremembertheday

whenwegraduatedfromthesameprimaryschool.分析：wegraduatedfrom....schoolon

theday.考点：在具体的某一天，要用介词on3.Doyoustillrememberthepark

wherewehadawonderfultime?分析：wehadawonderfultimein

thepark.请记住结论1：介词与先行词形成固定搭配Task3:

重点突破1-2(如何选用适当的介词)二、“介词+which/whom”引导的定语从句的其他情况Thetextbook____whichIoftenreferisveryhelpfulforwritingessays.考点：refertosth.参考某物Theonlinetool___whichIdependhelpsmecheckgrammarinwriting.考点：dependon

依赖，依靠Theteacher____whomIoftenturnforwritingadviceispatient.考点：turntosb.向某人求助Thefriend____whomIsharemywritingideaslivesnexttome.考点：sharesth.withsb.和某人分享某物toontowith请记住结论2：介词与从句中的谓语动词形成固定搭配Task4:

难点突破2(如何选用适当的介词)三、“介词+which/whom”引导的定语从句时的注意事项。1.介词后不能用that/who思考：下面的表达对吗？如何改正？ThebookfromthatIlearnedalotisuseful.2.不可拆分的短语动词(如lookafter,listento,takecareof等)，介词不能前置思考：下面的表达对吗？如何改正？Theoldmanafterwhomwearelookingiskind.3.书面语/正式语境中介词常前置Thelettertowhichherepliedwasfromhisteacher.whichTheoldmanwhomwearelookngafteriskind.Task5:

难点突破3(如何辨认省略关系词的定语从句)思考：定语从句中关系词何时可以省略？1.TheteacherIaskedforhelpiskind.考点：作介词的宾语，且无前介词时可省略关系词。2.ThebookIborrowedyesterdayisaboutwriting.考点：作及物动词的宾语时，可省略关系词。3.Heisnolongertheboyhewasthreeyearsago.考点：作表语时，可省略关系词4.ThewayhelearnsEnglishiseffective.考点：theway作先行词时，可省略关系词。练习：挑战一下吧：识别长句中的定语从句1.Wehaddecidedonkeyitemsfortheapartmentweweremovingtointown,donatedwhatwecould,andrentedaplacetostoreoursupposedlyimportantobjects.2.Thisenergytransitionisglobal,andtheamountofrenewableenergytheworldwillneedis“alittlebitmind-blowing,”saysmechanicalengineerKeithWipkeattheNationalRenewableEnergyLaboratory.结论：找名词或代词后无连接词的句子并判断其与名词或代词的关系提升训练：语法与写作1.吃早饭的人更有可能保持健康的体重。____________________aremorelikelytokeepupahealthyweight.2.书是知识和力量的源泉,我从中受益匪浅。Booksarethesourceofknowledgeandpower_______________________3.体育运动可能是几乎所有人都可享受的最受欢迎的娱乐形式。Sportsareperhap
