被动语态“五注意”动词的被动语态在语法中起着举足轻重的作用,也是历年高考考查的重点。在学习时我们应注意以下几点:一、掌握被动语态的时态动词的被动语态是由动词be加上过去分词构成,时态通过be表现出来。如:Breakfastisprovidedinourhotelfrom7to9o’clockonweekdays.(一般现在时的被动语态)Wehaven’tmovedintothenewhousebecausetheroomsarebeingpainted.(现在进行时的被动语态)Thesportsmeetwillbeputoffbecauseofthebadweather.(一般将来时的被动语态)Twobigtowerswerebeingbuiltthereatthattime.(过去进行时的被动语态)Myhometownwasliberatedin1949andnowithasbeenturnedintoabeautifulcity.(一般过去时的被动语态)Thedoctorhasalreadybeensentfor.(现在完成时的被动语态)Whenfirefightersarrived,thebigfirehadbeenputout.(过去完成时的被动语态)二、注意短语动词的被动语态有不少短语动词相当于及物动词,所以这些短语动词亦有被动语态。如:Manyinterestingexperimentsarecarriedoutinourlaboratory.Heisoftenmadefunofforthisbyhisclassmates.有些由“动词+名词+介词”构成的短语动词,变成被动语态时可以将其中的名词变为被动语态的主语。如:Gooduseismadeofthelibrary.(主动句是:Theymakegooduseofthelibrary.)三、不及物动词没有被动语态常见的不及物动词有:appear,arrive,belong,come,die,escape,fall,happen,last,remain,succeed,takeplace,occur等。如:Thetrainarrivedatthestation20minuteslate.Somethingunexpectedoccurred.ThefilmfestivaltakesplaceinOctober.四、有些动词的主动形式可以表示被动意义这类动词是一些表示主语特征、性质的不及物动词,如:sell,wash,wear,shut,open,read,write,cut,end,begin等;连系动词look,feel,taste,smell,sound等,也可用主动形式表示被动意义,但后要接形容词作表语,不能接副词。如:Thedoorwon’tshut.Theclothwasheswell.Theflowerssmellsweet.Thefoodtastesnice.五、某些系表结构中的形容词是由过去分词转化而来,虽然形式上是被动的,但描述的却是一种状态。常见的这类形容词有:interested,lost,dressed,surprised,engaged等。如:Hewasdressedinapoliceuniformatthattime.Thegirlwaslostintheforest.Myunclehasbeenengagedinthestudyofmedicinefor20years.
