被动语态教案被动语态（一）语态：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。（二）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：amisarespoken一般过去时：waswerespoken一般将来时：willshallbespoken现在进行时：amisarebeingspoken过去进行时：was/werebeingspoken现在完成时：havehasbeenspoken过去完成时：hadbeen+spoken（三）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。（四）主动语态变被动语态的方法（1）把主动语态的宾语变为被动语态的主语。（2）把谓语变成被动结构（be过去分词）（根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定be的形式）。（3）把主动语态中的主语放在介词by之后作宾语，将主格改为宾格。例如：Allthepeoplelaughedathim.Hewaslaughedatbyallpeople.Theymakethebikesinthefactory.Thebikesaremadebytheminthefactory.Hecutdownatree.Atreewascutdownbyhim.（五）含有情态动词的被动语态含有情态动词的主动句变成被动句时，由“情态动词be过去分词”构成WecanrepairthiswatchintwodaysThiswatchcanberepairedintwodays.Theyshoulddoitatonce.Itshouldbedoneatonce.（六）特殊情况1.Hemadetheboyworkfortwohoursyesterday.Theboywasmadetoworkbyhimfortwohoursyesterday.2.MotherneverletsmewatchTV.IamneverlettowatchTVbymother.3.JackgavePeteraChristmaspresentjustnow.AChristmaspresentwasgiventoPeterbyJackjustnow.PeterwasgivenaChristmaspresentbyJackjustnow.常见的句型结构：Itis(was)agreed(believed/decided/hoped/thought.）that.大家同意（相信、决定、希望、认为）.Itis(was)wellknownthat.众所周知Itis(was)takenforgrantedthat.被视为当然Itmustberememberedthat.务必记住.Itmustntbeforgottenthat.千万别忘记.Itis(was)said(reported，heard，told，suggested)that.据说(报道、听说、告知、建议.) 被动语态练习一1TheOlympicGames_everyfouryears.AareheldBwereheldCareholdingDwillho1d2.Intheartshowalotofenjoyment_toforeignfriendsbytheChinesepaintingsAisgivingBisgivenCwillgiveDhasgiven3.TodayChineseisbecomingmoreandmorepopular.It_in.manyschoolsaroundtheworld.A.teachesB.isteachingC.hastaughtD.istaught4.BaJin,oneofthegreatestwritersinChina,_asPeoplesWriter.A.isregardedB.hasregardedC.isregardingD.regards5.Usuallycomputers_tosearchtheInternet.A.useB.areusingC.areusedD.used6.-Doyouoftencleanyourclassroom?-Yes.Ourclassroom_everyday.A.cleanB.cleansC.iscleaned7.一DidyouhearthatwaterinTaiLakesmeltterrible?一YesInfact，it_.ThatsallbecauseofthepeopleandthefactoriesaroundApollutedBwaspollutedChaspollutedDwaspo11ute8.-Ourenvironmentisgettingworsethanbefore.-Youreright.ButthankstoEarthDay_,peoplehavedonemoreandmoreusefulthingstoprotect(保护)theearthsinceEarthDay.A.isstartedB.wasstartedC.hasstarted9.-IfeelveryhappythatI_tobethehost.-Congratulations!A.chooseB.amchosenC.waschosenD.havenchosen10.Manytreesandflowers_inourschoollastyear，andtheymadeourschoolabeautifulgardenAplantBplantedChaveplantedDwereplanted11.Somefamouspaintings_inthehallnextweek.A.willshowB.wereshownC.isshownD.willbeshown12.Atalkondevelopmentsinscienceandtechnologyintheschoolhallnextweek.A.givenB.willbegivenC.hasbeengivenD.gives13.-Greatchangeshavetakenplaceinthiscity.-Right.Manymoderntallbuildingshavebeen_thesedays.A.turnedupB.putupC.shownupD.fixedup14.Twelve-year-oldsshouldnottodriveinChina.A.allowB.beallowC.allowedD.beallowed15.Doyouoftencleanyourclassroom?Yes,ourclassroom_everyday.A.cleanB.cleansC.iscleanedD.cleaned
