不知道动作的执行者是谁。2. 没有必要指出动作的执行者是谁。3.需要强调或突出动作的承受者时。4.句子的主语是动作的承受者。5. 有些动词习惯上常用被动语态。被动语态结构中应注意的几个问题1. 主动句中在感官动词see、hear、watch、feel、notice等以及使役动词let、make、have等后跟省略to的不定式,变为被动句时,应加上不定式符号to。2. “不及物动词+介词/副词”构成的短语动词，变成被动句时，要把它们作为整体看待，介词或副词不可与动词拆开或漏掉。3. 含有双宾语的主动句变被动句时，可将主动句中的直接宾语或间接宾语变为被动句中的主语。第50页共50页如果把主动句中的直接宾语(指物)变为被动句中的主语，则需在间接宾语(指人)前加适当的介词to或for。常接to的动词有give,tell,lend,show,pass,hand等；常接for的动词有buy,get等。主动形式表示被动意义的情况1.动词open,read,sell,write,lock,clean,watch,cut,burn,drive等作不及物动词，且它们的主语为物时。2.某些系动词(如smell,look,taste,feel,sound等)描述某物特性时。3.beworthdoing中，doing表示被动意义。4.need/require＋doing相当于need/require＋tobedone，tobedone是不定式的被动结构。【中考链接】1.We________toreachforourdreamsinthegraduationceremonylastweek.(2021辽宁丹东)A.encourageB.areencouragedC.encouragedD.wereencouraged2.—________you________toJim’sbirthdaypartylastnight?—Yes,Iwas.ButIwastoobusytobethere.(2021辽宁朝阳)A.Did;invitedB.Were;inviteC.Was;invitedD.Were;invited3.—Eric,you_______togototheteachers’officejustnow.What'sup?—Wearen'tallowedtobringphonestoschool.Em,butIbroketherule.(2021湖北黄冈)A.toldB.tellC.aretoldD.weretold第50页共50页4.—Whatabeautifuldress!Perfectforyou!—Thankyou.It______bymymotherlastmonth.(2021湖南郴州)A.ismadeB.wasmadeC.made5.TheplayTeahouse________bythefamousChinesewriterLaoShe.(2021海南)A.wroteB.waswritingC.waswritten6.—WhyhaveIneverseenthiskindofmobilephone?—Becauseit________byHuaweilastmonth.(2021贵州铜仁)A.wasproducedB.wouldproducedC.hasproducedD.areproducedⅣ.Practice1.Workon4a:Readthesentencesin4aandrewritethesentencesusingthepassivevoice.2.Workon4b:Completethesentenceswithcorrectformsoftheverbsinthebox.eat,like,invite,tell,lock,ring,break,bring1)You____________tothepartylastnight,weren’tyou?Whydidn’tyougo?2)Theearthquakehappenedallofasudden,butluckilythevillagers_____________toasafeplace.3)Thedoor___________whenwearrived,sowe______thebell.4)Thestudents___________nottoeatordrinkinclass,butRuby______therulewhenshestartedeatingabiscuitinscienceclass.5)Thecookies__________bythehungrykidsinlessthan20minutes,andtheyreally_____them.3.Workon4c:Decidewhetheractiveorpassiveformsshouldbeusedinthesesentences.Writethe第50页共50页correctformsintheblanks.Thetelephone______________(invent)byAlexanderGrahamBell.He__________(born)in1847.Mr.Bell________(work)ontheinventionofthetelephonewithThomasWatson.In1875,Mr.Bell_________(learn)howtosendmusicalnotesthroughaninstrumentsimilartoatelephone.Finally,thetelephone_____________(invent)in1876.Thefirstsentencethat_________(say)onthetelephonebyMr.Bellwas“Mr.Watson,comehere;Iwanttoseeyou.”Todaythetelephone________(use)aroundtheworld.Ⅴ.LanguagepointOurparentsadvisedusnottogooutalone．我们的父母建议我们不要单独外出。advisev.劝告；建议advisesb.about/onsth.就某事向某人提出建议advisesb.todosth.
