被动语态：表示主语和谓语之间是_________关系

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。We

cleantheclassroomeveryday.Theclassroomiscleanedbyuseveryday.

主动被动被动语态的谓语动词结构为：be+动词的过去分词be有时态和人称的变化母亲节每年都被我们庆祝。母亲节去年都被我们庆祝。我们已经学过：一般现在时的被动语态一般过去时的被动语态Mother'sDayiscelebratedbyuseveryyear.Mother'sDaywascelebratedbyuslastyear.Review一般现在时的被动语态is/are+动词过去分词一般过去时的被动语态was/were+动词过去分词被动语态我们已经学习了一般现在时的被动语态和一般过去时的被动语态，它们的结构为：时态被动语态结构一般现在时am/is/are+及物动词的过去分词一般过去时was/were+及物动词的过去分词Whatwillwelearntoday？Idon’tthinksixteen-year-oldsshouldbeallowedtodrive.Iagree.Theyaren’tseriousenough.Doyouthinkteenagersshouldbeencouragedtomaketheirowndecisions?No,Idon’tagreewiththis.Teenagersaretooyoungtomaketheirowndecisions.Teenagersshouldnotbeallowedtohavepart-timejobs.Idisagree.Theycanlearnalotfromworking.Doyouthinkwemaybeallowedtotakephotosifwedon’tuseaflash?Ifyoudon’tuseaflash,thenitmaybeOK.GrammarFocusReadthefollowingsentencesandfindoutthecommonfeatures.含有情态动词的被动语态的结构为：情态动词+be+及物动词的过去分词;变为否定句时只需要在情态动词后加notcan/couldmay/mightwill/wouldshall/shouldmustoughtto1.情态动词无时态和人称的变化；2.情态动词后动词变回原形。情态动词1.定义

含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。初中阶段的常见情态动词有：can,may,need,must,should等。含情态动词的被动语态2.构成：情态动词+be+过去分词eg:Moretreesshouldbeplantedinthe

town.镇上需要种更多的树。

Tablescanbemadeofstoneorwood.桌子可以由石头或木头制成。句式结构示例肯定句主语+情态动词+be+及物动词的过去分词(+by…)Teenagersshouldbeallowedtogoshopping.否定句主语+情态动词+not+be+及物动词的过去分词(+by…)Thewordcan’tbeusedinthissentence.一般疑问句情态动词+主语+be+及物动词的过去分词(+by…)?Musttheworkbefinishedtoday?特殊疑问句特殊疑问词+情态动词+主语+be+及物动词的过去分词(+by…)？Whoshouldbeaskedforhelp?3.句式含情态动词的被动语态e.g.Manytrees

shouldbeplanted

inthemountains.Thisbook

canbetaken

home.Thisproblem

can’tbeworkedout

veryeasily.Must

thework

befinished

atonce?【拓展】“动词+名词+介词”构成的短语动词(如takecareof,payattentionto等)变为被动句时，通常把整个短语当作一个及物动词来处理。e.g.Youshouldpayattentiontoyourhealth.→Yourhealthshouldbepaidattentionto.含有情态动词的主动句变为被动句时，有如下步骤：（1）把主动句的宾语变为被动句的主语；（2）主动句中的谓语变为“情态动词+be+及物动词的过去分词”；（3）主动句的主语在被动句中变为by的宾语；（4）其他成分不变。主动句：Weshouldplanttreesinspring.被动句：Treesshouldbeplantedinspring.4.含有情态动词的主动句与被动句之间的转换将下面三个句子改写成被动语态。1.Hecleanshisbedroomeveryday.2.Hecleanedhisbedroomyesterday.3.Heshouldcleanhisbedroominthemorning.______________________________________Hisbedroomiscleanedbyhimeveryday.Hisbedroomwascleanedbyhimyesterday.____________________________________________________________________________Hisbedroomshouldbecleanedbyhiminthemorning.一般疑问句:直接将被动语态的陈述句中的情态动词提前。eg:Mustthistaskbefinishedatonce?这项任务必须立即完成吗？

注意:

含情态动词的被动语态的一般疑问句的回答，应保留原情态动词，但must表“必须”时，其否定回答应用needn’t；need表“必要”时，其肯定回答应用must。如：—Mustmyexercisebookbehandedinnow?我的练习本必须现在上交吗？—Yes,itmust.

是的，必须现在上交。（No,itneedn’t.

不，不必现在上交。）5.句式变换5.句式变换否定句：在情态动词后面加上not或never即可，但must表“必要”时否定式为needn’t。eg:Thistaskneedn’tbefinishedatonce.这项任务没必要立即完成。特殊疑问句：由特殊疑问词加上被动语态的一般疑问句构成。eg:Whenmustthistaskbefinished?这项任务必须在什么时候完成？反意疑问句：借助情态动词构成附加疑问部分。如：eg:Thisbridgecanbebuiltnextyear,can’tit?这座桥明年能建成，是吗？GrammarFocusCloseyourbookandtrytofillintheblanks.1.我认为十六岁的孩子不应该被允许开车。Idon’tthinksixteen-year-olds_____________________todrive.我同意。他们还不够认真。

attentionto.一些动词短语用被动语态时，动词短语应视为一个整体，而不能丢掉其中的介词或副词。注意事项二：Weshouldmakeourcountrybecomemoreandmorebeautiful.→Ourcountryshouldbemadetobecomemoreandmorebeautiful.make，see，watch，hear，notice，feel等使役动词和感官动词在主动语态中与省略to的动词不定式连用，但变为被动语态后，必须加上to。注意事项三：Thepearsmusttastedelicious.look,sound,taste,smell等系动词用主动结构表被动意义。

注意事项四：Hisnewbookwillsellwell.

不及物动词与状语连用，用以表示主语的品质和状态。常见的此类动词有：cut，sell，read，write，fill，cook，lock，wash，drive，keep等。

注意事项五：含有宾语从句的主从复合句中的否定转移的用法。当动词think,believe,suppose,imagine,expect,feel的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时，它们的否定式实际上是对宾语从句的否定。表示说话者提出一种委婉的看法或主张。Ithinkthathewillhelpus.—Idon'tthinkthathewillhelpus.

我认为它不会帮助我们。Ibelievethatheisright.—Idon'tbelievethatheisright.

我认为他不对。Isupposethathelikesit.—Idon'tsupposethathelikesit.

我想他不喜欢它。Idon’tthinksixteen-year-oldsshouldbeallowedtodrive.应该翻译为：我认为十六岁的孩子们不应该被允许开车。

含情态动词的被动语态的“发生”takeplace不及物动词短语发生；出现；举行（某事）按计划进行或按计划发生happen不及物动词发生常指具体事件的发生，特别指那些偶然的或未能预见的“发生”takeplace和happen没有被动语态
