语态：表示主语和谓语动词之间的关系。英语有两种语态，即主动语态和被动语态。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。如：Manystudents

study

English.(主动语态)English

isstudied

bymanystudents.(被动语态)语态肯定句：主语＋be+过去分词＋(by~)否定句：主语＋benot＋过去分词＋(by~)一般疑问句：Be＋主语＋过去分词＋(by~)?特殊疑问句：疑问词＋be＋主语＋过去分词＋(by~)被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be动词后面的过去分词不变。bymanystudents.Englishisstudiedbymanystudents.Englishisnotstudiedbymanystudents.主动语态变被动语态的方法1.ManystudentsstudyEnglish.Englishisstudied2.Theymakeshoesinthatfactory.Shoesaremadebytheminthatfactory.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.把主动语态的谓语变为被动语态的谓语。3.把主动语态的主语变为被动语态的by

这些书是为儿童写的。Ihaven’tbeentoldaboutit.没有人告诉我这件事被动语态的用法（1）不知道或没有必要说明动作的执行者是谁.It’s/wassaid/believed/reported/+that…It’sreportedthataboutthreehundredpeoplewerekilledinthisearthquake.

据报道，这次地震中大约有三百人死亡。（2）强调动作的承受者，这时应用by短语。ThecupwasbrokenbyDavid.（3）作客观说明时，常采用一种被动语态句型.如：1.Hegavemeabook.－Iwasgivenabookbyhim.（以I做主语）－AbookwasgiventomebyTom.（以物book作主语）

注意事项1.带双宾语句子的被动语态.（指物的宾语叫直接宾语，指人的宾语叫间接宾语）常见的接双宾语的动词有:七给一带:pass,give,show,hand，send,write,bring买画唱做:make,buy,draw,sing,get,以“人”当主语时，变法和一般的变法一样；以“物”当主语时，在保留的间接宾语前必须加to或for.七给一带to不少，买画唱做for来帮keep,make三类的动词常常有宾语补足语，在被动语态中，宾语补足语位置不变。

We

keep

food

freshinthefridge.主谓宾宾补－Foodiskeptfreshinthefridge.Isawhimgointotheofficebuilding.－Hewasseentogointotheofficebuilding.2.含有宾语补足语的句子的被动语态不及物动词没有宾语，因此没有被动语态。但有的不及物动词后面加上介词及其他一些词类构成短语动词之后，其作用相当于及物动词，可以接宾语，因而也可以变为被动语态。在变成被动语态时，不能去掉构成短语动词的介词或副词.Theytakegoodcareofmychild.Mychildistakengoodcareof.Iturnedofftheradio.Theradiowasturnedoff(byme)

3.含有短语的主动语态变被动语态即feel,hear,listen,have,make,let,look,watch,see,notice，这些词在主动句中，其后的动词不定式不加to，但变被动句时必须加to.1.IsawhimplaybasketballlastSunday.HewasseentoplaybasketballlastSunday.2.Weheardthemsingintheclassroom.Theywasheardtosingintheclassroom.4.感官动词和使役动词的被动语态（1）当主动结构中的宾语是反身代词和相互代词时，不能改为被动语态。Weoftenhelpeachother.

我们常常互相帮助。（2）当谓语是表状态的及物动词时（如have,like,takeplace,belongto…）如：

Iliketheseflowers.我喜欢这些花。

Iwillhaveameeting.

不说Ameetingwillbehad.应说Ameetingwillbeheld.5.不能用于被动语态的几种情况把下列句子变成被动语态:Acarknockedhimdownyesterday.2）Twodoctorsandtennursesmakeupthemedicalteam．3）WhenIgotthere,theywerecuttingupafallentree．Afallentreewasbeingcutup,whenIgotthere.Hewasknockeddownbyacaryesterday．Themedicalteamismadeupofbytwo…．PracticeTheplaywillbeputonnextSunday．Anewteachingbuildingisbeingbuiltbyworkersinourschool．1.Insomecountries,tea______withmilkandsugar.A.isservingB.isservedC.servesD.served2.Greatchanges_____inmyhometownsince1980.A.havebeentakenplaceB.tookplaceC.havetakenplaceD.weretakenplace3.Thenewtypeofcarisgoingto______inthreeyears.A.turnoutB.beturnedoutC.hasturnedoutD.havebeenturnedout4.Thewomanmurderedherfriendand______to______.A.wassentenced,deathB.sentencing,dieC.sentenced,deathD.sentenced,die被动语态专项练习：选择填空5.－Doyouliketheskirt?－It_______soft.A.isfeelingB.feltC.feelsD.isfelt6.Areyoustillhere?Youwerehereanhourago.Who________for?A.areyouwaitingB.didyouwaitC.wereyouwaitingD.doyouwait7._____toknowProfessorZhang.A.HesaidB.IsaidC.HeissaidD.Itsays8.－Iwanttositatthetablenearthewindow.
