1.不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者。2.强调动作的承受者。二、将主动语态变为被动语态应注意的几种情况1.含双宾语的主动结构变为被动结构时,有两种方法:(1)间接宾语变为主语,直接宾语不变;(2)直接宾语变为主语,间接宾语用介词to或for引导。2.动词短语视为一个整体,其后的介词或副词不能省去。3.复合句通常将宾语变为被动句的主语,而宾语补足语就成为主

语补足语。注意:省略to的不定式作宾语补足语时,不定式符号

to必须补上。三、常见主动表被动的情况1.有些动词(cut,sell,read,write,fill,cook,lock,wash,drive,keep等)常用主动形式表被动。2.在某些形容词(hard,difficult,easy,heavy,fit,good,comfortable,convenient,impossible,cheap,expensive等)后的不

定式用主动形式表被动。3.“半系动词+形容词”结构,look,smell,taste,sound,feel,prove,turnout等。4.need,want,require,deserve,beworth后面接动词的-ing形式,主

动表被动。Task2Readandcompletethefollowingsentenceswithappropriateformsofthewordsinbrackets.Thenthinkaboutwhythepassivevoiceisusedinthesesentences.1.Mobilephonesmust______________duringtheconcert.(switchoff)2.WhenIcamehereatthistimelastyear,theconferencehall______________.(build)3.Topicslikelifeinthefuture,AIdevelopment,andaliens_____________insci-fi.(oftenfound).4.Doyouknowwhichcountry___________byItaly,Austria,Germany,andFrance?(border)beswitchedoffwasbeingbuiltareoftenfoundisbordered5.Continuousresearch_________________onsmartschools,smarthomes,andsmartcities.(conduct)6.Itshould________thattheresultofyourexaminationswillnot____________.(note;publicise)7.It___________thatmorespecieswillbecomeextinctifwecontinuetodestroytheecosystem.(assume)8.Allmembersoftheaudienceshould__________smartly,andthewearingofslippers_____________intheconcerthall.(dress;notallow)hasbeenconductedbepublicisedisassumedbedressedbenotedisnotallowedActivity3:Reflecting.◎Whatinterestingthingsaboutsciencefictiondidyoulearninthisunit?◎Whatnewvocabularyandstructuresdidyoulearninthisunit?Howwellcanyouusethem?◎Doyouthinkcomparingandcontrasting,andlisteningfordiscoursemarkerswereusefulstrategiesforyoutounderstandthetexts?◎Whatproblemsdidyouhavewiththisunit?Howdidyousolvethem?◎Overall,Ithoughtthisunitwas○inspiring○useful○so-so
