Passivevoice复习目标1、掌握语态基本概念；2、熟悉常见语态转换；3、在习题中理解和运用被动语态。复习重点:1.一般现在时和一般过去时的被动语态；2.情态动词的被动语态。3.一般将来时和现在完成时的被动语态。复习难点:1.被动语态中be形的确定；2.主动语态中省略to的宾补在被动语态中须补上to.基础知识回顾1、观察结构执行者+动词+承受者Workersmakecarsinthisfactory.主谓宾承受者+be+动词过去分词+(by+执行者)Carsaremade(byworkers)inthisfactory.主谓2、总结概念：谓语动词的执行者作主语，用主动语态。谓语动词的承受者作主语，用被动语态。3.用法：a.当不知道谁是动作的执行者时；b.没有必要或不想指出谁是动作的执行者时；c.只需强调动作的承受者时。•TheflowersWhatdoesshedoeveryday?everyday.arewateredbyherShewaterstheflowerseveryday.主谓宾后面能接宾语的动词才有被动语态（及物动词）。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.歌诀是：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。[注意]①把主动语态改为被动语态时，句子的时态不能变。且be动词和新主语保持一致。如上例，所给的主动句子是一般现在时，改为被动语态时，也要用一般现在时。②如果主动句中的主语是人称代词，改为被动句时作介词by的宾语，要用宾格。如上例中的主语they改为them。be+P.P.be+P.P.被动语态的基本结构:有各种时态的变化考点一:考点一:[1].NowEnglish____bymoreandmorepeopleallovertheword.A.speaksB.isspokenC.wasspoken一般现在时的被动语态：am/is/are+PP一般现在时的被动语态：am/is/are+PPtask（一）1.WelikeMissLinVerymuch.MissLin___________byusverymuch.2.ManyyoungpeopleloveJolion’songs.Jolin’ssongs__________bymanyyoungpeople.islikedareloved时态:结构：am/is/are+过去分词一般现在时把下列句子改为被动语态：[2].Thelostboy____atthestreetcornerlastnight.A.wasfoundB.isfoundC.waslookedfor一般过去时的被动语态：was/were+PP一般过去时的被动语态：was/were+PPtask（二）1.Themanrepairedthecaryesterday.Thecar_____________bythemanyesterday.2.MrSongencouragedustostudyhardlastweek.We________________tostudyhardbyMissPenglastweek.wasrepairedwereencouraged时态:结构：was/were+过去分词一般过去时把下列句子改为被动语态：[3].Manyhouses____inthefuture.A.willbuildB.willbebuiltC.arebuilt一般将来时的被动语态：will+be+PPbegoingto+be+PP一般将来时的被动语态：will+be+PPbegoingto+be+PPtask(三)1.Thecitywillbuildthenewairportnextyear.Thenewairport________________nextyear.2.HongxingMiddleSchoolisgoingtosendtwostudentstoHongkongtostudy.Twostudents____________________toHongkongtostudy.willbearebe时态:结构：will/begoingto+be+过去分词一般将来时builtgoingtosent[4].Threebridges____sincelastyear.A.havebuiltB.werebuiltC.havebeenbuilt现在完成时的被动语态：have/has+been+PP现在完成时的被动语态：have/has+been+PPtask(四)1.LiMinghasalreadywateredsomeflowers.Someflowers________________byLiMingalready.2.Theyhavesoldoutthelightgreendress.Thelightgreendress____________________________out.havebeenhas时态:结构：Have/has+been+过去分词现在完成时wateredbeensold[5].Flowers____everyday.A.hasbeenwateredB.shouldbewateredC.shouldwater含有情态动词的被动语态：情态动词+be+PP含有情态动词的被动语态：情态动词+be+PP含有情态动词的被动语态：情态动词+be+过去过去分词分词1.Youmustn’tcleantheroomtoday.Theroom____________...
