Passivevoice被动语态（ThePassiveVoice）：1）主动语态和被动语态：英语动词有两种语态，即主动语态（TheActiveVoice）和被动语态（ThePassiveVoice）。主动语态表示主语是动作的执行者，被动语态表示主语动作的承受者。如：ManystudentsstudyEnglish.(主动语态)Englishisstudiedbymanystudents.(被动语态)2)被动语态的结构：被动语态由“助动词be+及物动词的过去分词”构成，助动词be有人称、数的变化,其变化规则与be作为连系动词时一样。ThePassivevoice动词被动语态:be+过去分词（及物动词）被动语态是英语动词的一种特殊形式.汉语中往往用“被”“受”“给”等词来表示被动意义.主动语态变为被动语态的方法:1.主动句中的宾语变成被动句的主语.2.主动句中的谓语动词变成被动句的be+过去分词.3.主动句中的主语变成被动句by的宾语,放在谓语动词后面.如果不强调动作执行者时,by短语可省略.Heplantstreesinspring.主谓宾(受动者)Treesareplantedbyhim改为被动语态inspring.Tomwillcleantheroomtomorrow.主谓宾(受动者)TheroomwillbecleanedbyTomtomorrow.Hisbrotherwashesbowlseveryday.主谓宾(受动者)Bowlsarewashedbyhisbrothereveryday.1.Theymakeshoesinthatfactory.主语+及物动词+宾语Shoesaremade(bythem)inthatfactory.一般现在时：S(主语）+am/is/are+过去分词2.Theyboughttencomputerslastterm．Tencomputerswerebought(bythem)lastterm.一般过去时：S+was/were+过去分词3．AmycantakegoodcareofGina．GinacanbetakengoodcareofbyAmy.情态动词：S+can/may/must/should+be+过去分词Hissister4.Hewilltakehissistertothepark?willbetakentotheparkby一般将来时：S(主语)+willbe+过去分词him?5．Wehavemadetwentymorekeys．Twentymorekeyshavebeenmadebyus.现在完成时：S+have/has+been+过去分词6.Someworkersarepaintingtheroomsnow．Theroomsarebeingpaintedbysomeworkersnow.现在进行时：S+am/is/are+being+过去分词7．Iwasdoingmyhomeworkat8:00lastnight．Myhomeworkwasbeingdone(byme)at8:00lastnight.过去进行时：S+was/were+being+过去分词时态被动语态结构一般现在时一般过去时一般将来时am/is/are+donewas/were+doneShall\willbe+done情态动词+be+done过去将来时现在完成时过去完成时wouldbe+donehave/hasbeen+donehadbeen+done现在进行时过去进行时was/werebeing+doneam/is/arebeing+done主动语态变成被动语态时要注意以下几点:1.含有双宾语的主动句变成被动句时,可以将其中一个宾语变为主语,另一个不动.一般把间接宾语变为主语.如:Marygavemeapen.IwasgivenapenbyMary.如果把直接宾语变为主语,则在间接宾语前加“to\for”如:ApenwasgiventomebyMary.2.含有复合宾语的主动句变为被动句时,将其中的宾语变为主语,宾补不变.如:Weaskedhimtospeakatthemeeting.Hewasaskedtospeakatthemeeting.3.如果主动句中的谓语是短语动词,变为被动句时,短语动词的介词或副词不可以丢掉.如:Theytookgoodcareoftheboys.Theboysweretakengoodcareof.4.在“let,make,see,hear,notice,watch,feel”等动词后面做宾语补足语的动词不定式不带“to”,但改成被动句时应加上“to”.如:Thedoctormademestayinbedforthreedays.Iwasmadetostayinbedforthreedaysbythedoctor.1.Hetellsusastoryeveryevening.Wearetoldastorybyhimeveryevening.Astoryistoldtousbyhimeveryevening.2.Heboughtmeanewbikeyesterday.Iwasboughtanewbikeyesterday.Anewbikewasboughtformeyesterday.3.Willhetakehissistertothepark?Willhissisterbetakentotheparkbyhim?4.Heislookingforthelostkey.Thelostkeyisbeinglookedforbyhim.5.Thebossmadehimdotheheavywork.Hewasmadetodothehomework(bytheboss).6.Weoftenhearhimplaytheguitar.Heisoftenheardtoplaytheguitar•Atrafficaccident________(happen)justnow.happened2.连系动词（Link.v.)如：be,look,seem,feel,sound,smell,taste,get,turn,become…•PekingOpera________(sound)beautiful.sounds3.当此动词表示事物的自然属性的时候:•Thepen_________(write)veryfast.writes•Thiskindofsweater_______(sell)well.sells1.不及物动词（vi.)如:happen,takeplace,appear,dissapear,…不用被动语态的动词：1)Teenagersshould_____(allow)togooutatnight.2)Thetelephone_____(invent)byBell.3)English____(speak)inChina.4)Thecar____(make)inChina.5)Theroommust_____(clean)everyday.beallowedwasinventedisspokenismadebecleaned
