被动语态教学目标知识与能力：掌握主动语态、被动语态互变，被动语态的时态及用法。过程与方法：通过比较、讲解、训练使学生学会运用被动语态。情感价值观：通过学习，学会变被动学习为主动学习。教学重点：被动语态的基本运用教学难点：主动语态、被动语态互变，被动语态的时态及用法。教学方法：讲练结合法，比较法教学准备：多媒体课件Step1:Greetandrevision1.Greetthestudentswitheachother.2.Reviewallthetensesthathavelearnt.Step2:语态概述英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者。例如：ManypeoplespeakChinese.谓语：speak的动作是由主语manypeople来执行的。被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chineseisspokenbymanypeople.主语English是动词speak的承受者。Step3:被动语态的构成被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以speak为例说明被动语态在各种时态中的构成。一般现在时：am／is／are＋spoken一般过去时：was／were＋spoken被动语态的构成一般将来时：will／shallbe＋spoken现在进行时：am／is／arebeing＋spoken过去进行时：was/werebeing＋spoken现在完成时：have／hasbeen＋spoken过去完成时：hadbeen+spokenStep4:被动语态的用法（1）不知道或没有必要说明动作的执行者是谁。例如：Somenewcomputerswerestolenlastnight.一些新电脑在昨晚被盗了。（不知道电脑是谁偷的）Thisbridgewasfoundedin1981.这座桥竣工于1981年。（2）强调动作的承受者，而不强调动作的执行者。例如：TheglasswasbrokenbyMike.玻璃杯是迈克打破的。Thisbookwaswrittenbyhim.这本书是他写的。Yourhomeworkmustbefinishedontime.你们的家庭作业必须及时完成。Allthepeoplelaughedathim.Hewaslaughedatbyallpeople.Theymakethebikesinthefactory.Thebikesaremadebytheminthefactory.Hecutdownatree.Atreewascutdownbyhim.Homework:复习记忆被动语态及相关用法板书设计：被动语态的构成：被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以speak为例说明被动语态在各种时态中的构成。一般现在时：am／is／are＋spoken一般过去时：was／were＋spoken被动语态的构成一般将来时：will／shallbe＋spoken现在进行时：am／is／arebeing＋spoken过去进行时：was/werebeing＋spoken现在完成时：have／hasbeen＋spoken过去完成时：hadbeen+spoken随堂检测：单项选择1()1ThePeople'sRepublicofChina___onOctober1,1949.A.foundB.wasfoundedC.isfoundedD.wasfound()2English____inCanada.A.speaksB.arespokenC.isspeakingD.isspoken()3ThisEnglishsong___bythegirlsafterclass.A.oftensingsB.oftensangC.isoftensangD.isoftensung()4Thiskindofcar___inJapan.A,makesB.madeC.ismakingD.ismade()5Newcomputers___allovertheworld.A.isusedB.areusingC.areusedD.haveused2()1Ourroommust___clean.A.keepB.bekeptC.tobekeptD.tokeep()2-I'dliketobuythatcoat.-I'msorry.___.A.itsoldB.it'ssellingC.It'sbeensoldD.ithadbeensold()3Anewhouse___atthecorneroftheroad.A.isbuildingB.isbeingbuiltC.beenbuiltD.bebuilding()4Thekey___onthetablewhenIleave.A.wasleftB.willbeleftC.isleftD.hasbeenleft()5Doctors___ineverypartoftheworld.A.needB.areneedingC.areneededD.willneed4()1-Myshoesarewornout.-___.A.Can'ttheybemended?B.Letmehavealookatit.C.Howmuchdotheycost?D.Can'ttheymended?()2___thewatchbeenrepairedyet?Ibadlyneedit.A.DoesB.HasC.IsD.Are()3___thesedesksbeneeded?A.WillB.AreC.HasD.Do5()1Why___totalkaboutityesterday?A.didn'tameetingholdB.wasn'tameetingheldC.wasn'theldameetingD.ameetingwasn'theld()2Whowasthebook___?A.writeB.wroteCwrittenD.writtenby作业：1()1Why___totalkaboutityesterday?A.didn'tameetingholdB.wasn'tameetingheldC.wasn't...
