被动语态公开课课件(1)

被动语态,ThePassiveVoice,一、主动语态与被动语态主动语态表示主语是动作的执行者。被动语态表示主语是动作的承受者。Model:ManypeoplespeakEnglish.（主动语态）Englishisspokenbymanypeople.（被动语态）二、被动语态的构成：be+done（过去分词）、一般现在时：amisdoneare、一般过去时：wasdonewere,.,3.现在完成时:havebeendonehas4.现在进行时:amisbeingdoneare5.一般将来时：willbedoneshall6.含有情态动词:canmaymustbedoneshouldhaveto,三、被动语态的用法、不知道谁是动作的执行者要用被动语态，如：Thisjacketismadeofcotton.、没有必要指出谁是动作的执行者时要用被动语态，如：EnglishisspokeninBritainandAmerica.、只需强调动作的承受者时要用被动语态，如：Thebridgewasbuiltin1990.四、把主动句变为被动句的方法：在主谓宾结构中、把主动句的宾语变为被动句的主语，主动句的主语变为by短语（没必要时可省），如：Bellinventedthetelephonein1876.ThetelephonewasinventedbyBellin1876.,练习一Mymothermadethesoup.2.UncleWangwillrepairmycomputer.Youmustcleanyourroomonceaweek.Theboybrokethewindow.Theworkersarebuildinganewbridge.,Thesoupwasmadebymymother.,MycomputerwillberepairedbyUncleWang.,Yourroommustbecleanedonceaweek(byyou).,Thewindowwasbrokenbytheboy.,Anewbridgeisbeingbuilt(bytheworkers).,Icannotfindmydictionary.DostudentslearnEnglishinthemiddleschool?,Mydictionarycannotbefoundbyme.,IsEnglishlearnedinthemiddleschoolbystudents?,、在主谓宾结构变为被动语态时，只将其中一个宾语变为被动句中的主语，另一个宾语不变，如：Hetoldheralongstory.宾宾Shewastoldalongstory.Alongstorywastoldtoher.Motherboughtmeanewcoat.宾宾Iwasboughtanewcoat.Anewcoatwasboughtforme.,、“主谓宾宾补”句型变为被动结构时，只将句中的宾语变为被动句中的主语，宾补不变。如：Ifoundhimlyingonthefloor.宾宾补Hewasfoundlyingonthefloor.WecallherRose.宾宾补SheiscalledRose.、当主动句中有see/hear/feel/watch/notice/make/havesbdosth变为被动句时，do前要加上to.如：Ioftenhearhimsing.Heisoftenheardtosing.Theymadetheboygotobedearly.Theboywasmadetogotobedearly.,四、使用被动语态时应注意：有些动词形式上主动，意义上是被动，用时特别要小心。、可和well等连用的及物动词。Mypenwriteswell.我的笔好使。Theclothwasheswell.这个料子耐洗。Thepoemreadssmoothly.这首诗读起来很流畅。、be+形todosth.Thestoryisinterestingtoread.Thewineisnicetodrink.,练习二1.Myparentsboughtmeabike.2.Havetheypaidyouthemoney?3.Heistellingusafunnystory.JackgaveJimapresent.,Iwasboughtabikebymyparents.Abikewasboughtformebymyparents.,Haveyoubeenpaidthemoney?B.Hasthemoneybeenpaidtoyou?,Wearebeingtoldafunnystory.Afunnystoryisbeingtoldtous.,JimwasgivenapresentbyJack.ApresentwasgiventoJimbyJack.,、某些连系动词Theflowerssmellsweet.这花儿很香。Thefoodtastesnice.这食物味道好。、下列词不用被动形式：last(持续),have(有)，wish,let,takepartin,breakout(爆发),happen.Ihavetwobrothers.Ididntlethimgohome.,练习三Hetoldustowaitforhimattheschoolgate.Wemustkeeptheenvironmentclean.Motheroftenmakesmefinishmyhomeworkfirst.Wesawhergooutoftheschool.IoftenhearhimreadEnglishinthemorning.,Weweretoldtowaitforhimattheschoolgate.,Theenvironmentmustbekeptclean.,Iamoftenmadetofinishmyhomeworkfirst.,Shewasseentogooutoftheschool.,HeisoftenheardtoreadEnglishinthemorning.,Exercises一、将下列句子改为被动语态1.ManypeoplespeakEnglishintheU.S.A.EnglishisspokenbymanypeopleintheU.S.A.2.Iwillfinishtheworksoon.Theworkwillbefinishedsoon.3.Heboughtabike.Abikewasboughtbyhim.4.Youshoulddotheworkcarefully.Theworkshouldbedonecarefully.5.Theyarewateringtheflowers.Theflowersarebeingwateredbythem.6.Weheardthemsinginthenextroom.Theywereheardtosing(byus)inthenextroom.,二、变下列句子为主动句（括号内有词的，用其作主语）1.Nobodywasfoundintheroom.(they)Theyfoundnobodyintheroom.2.Anewbridgewillbebuiltnextyear.(they)Theywillbuildanewbridgenextyear.3.Thebikemustbemended.(Jack)Jackmustmendthebike.4.Keysareusedbypeopleforlockin
