定语从句教案教学设计一.什么是定语从句阅读下列句子，找出哪一句是定语从句1.Mydoctortoldmetolivewheretheairisfresh.2.Tomwassleepingwhenthedoorbellrang.3.DoyouremembertheteacherwhotaughtusEnglishatmiddleschool?4.CanyoutellmewhentheFlight5571willdepart?在复合句中充当定语的从句叫定语从句。定语从句的作用相当于形容词，用来修饰主句中的某一个名词或代词或整个句子。被定语从句修饰的词叫先行词，定语从句一般紧跟在它所修饰的先行词之后。因此，通常定语从句被视为一个句子与一个名词的关系。在先行词和定语从句之间起连接作用的叫关系词。关系词有关系代词和关系副词两种。例如：Heistheboywhooftengoestoschoollate.注意关系词在定语从句中的三大作用：1.连接作用———连接先行词和定语从句。例如：IgaveherallthemoneythatIhad.我把我所有的钱都给了他。（that连接先行词money和定语从句Ihad）.2.替代作用———在定语从句中替代从句所修饰的先行词。例如：Themanwholivesnextdoorisafamousteacher.2.成分作用———在定语从句中作主语、宾语、定语或状语。例如：IlikepictureswhicharepaintedinthetraditionalChinesestyle.我喜欢传统的中国画（which在定语从句中作主语）。二.关系代词和关系副词的用法阅读下面的句子，根据从句的语法特点将其归类，幷把句子序号表格填入空缺处。1.Sheistheoldwomanthatwitnessedtheaccidentthismorning.2.MaryisthegirlwhoworksinJapan.3.Isthisthekeywhichyouarelookingfor.?4.October1,1949isthedaywhenNewChinawasfounded.5.Thehousewhichstandsonthetopofthehillwasbuiltlastmonth.6.ThestudentwhomtheteachersaretalkingabouthaswonthefirstprizeintheEnglishcontest.7.Heliedtothepoliceofficer,whichmadethingsevenworse.8.Thismagazinebelongstotheteacherwhoteachesushistory.9.TomisreadingintheroomwheretheothersarewatchingTV.10.Hefailedintheexam,whichsurprisedusall.11.Idon’tknowthereasonwhyshelooksunhappytoday.12.I’llneverforgetthedaywhenIjoinedtheLeague.13.He’sgothimselfintoadangeroussituationwhereheislikelytolosecontrolovertheplane.关系代词和关系副词的用法定语从句类型特点句子序号由关系代词which/that/who/whom引导关系代词在从句中作主语关系代词在从句中作宾语关系代词which指代前句所属之事由关系副词when/where/why引导定语从句中不缺主语或宾语；when/where/why充当从句的时间、地点、原因状语。Where所指代的是一个抽象的地点，例如某一种情况、某一个领域。巩固练习完成句子1.AlexanderBellwastheman_______________________(发明电话的人)。2.Thepresent____________________________________(她生日那天我送她的)isstillunopened.3.CarolsaidtheworkwouldbedonebyOctober.__________________________，(我对此十分怀疑)。4.Thefilmbroughtthehourstome__________________________________(当时我得到很好的照顾)inthefarawayvillage.5.Wearelivinginanage______________________________(我们生活在一个很多事情需要用电脑来做的时代)。单项选择1.Doyoustillrememberthechickenfarm_________________wevisitedthreemonthsago.AwhereBwhenCthatDwhat2.Women_______drinkmorethantwocupsofcoffeeadayhaveagreaterchanceofhavingheartdiseasethanthose_______don’tAwho/B/whoCwhowhoD//3.Helenwasmuchkindertoheryoungestsonthantotheothers,_______,ofcourse,madetheothersenvyhim.AwhoBthatCwhatDwhich4.Ifashophaschairs_______womencanparktheirmen,womenwillspendmoretimeinshop.AthatBwhichCwhenDwhere5.Iworkinabusiness_________almosteveryoneiswaitingforagreatchance.AhowBwhichCwhereDthat三关系词使用的注意事项引导定语从句的关系词的选用比较复杂。除了牵涉到所指的先行词是人还是物，所引导的定语从句是限制性的还是非限制性的，以及关系词在从句中充当什么句子成分外，还要根据习惯用法而定。（一）只能使用that,who,whose的定语从句。请阅读以下句子，根据用法分类，将句子序号填入表格中适当的位置。1．ThisisthelongestbridgethatIhaveeverseen.2．Ihappenedtobethethousandthguestthatvisitedthegreathotel.3．Hetalkedabouttheteachersandschoolsthathehadvisited.4．Whoisthemanthatcamethismorning?5．Whichisthebagthatyoulost?6．Heistheverypersonthatthepolicearelookingfor.7．ThisistheonlythingthatIcanremember.8．Telluseverythingthatyouknow,please.9．Isthereanythingthatyoudon’tunderstand?10．Allthatglittersisnotgold.11．Anyonewhobreaksthelawshallbepunished.12．Hismother,wholoveshimverymuch,isstrictwithhim.13．Hereistheboywhowantstoseeyou.14．Thosewhoareagainsttheplanputupyourhandsplease.15．MaryisthegirlwhoseparentsworkinJapan.16．LastweekIboughtacar,whosepriceisreasonable.
