一般现在时态的被动语态讲解练习

一般现在时态的被动语态概念理解1.时态：在英语语言中，时态主要讨论行为动词发生的时间。英语中常用的时态有：一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时等。语态：在英语语言中，语态主要讨论句子主语与行为动词的关系。语态有两种：主动语态和被动语态。①主语是动作的发出者(执行者)为主动语态。如：ThemostpeopleintheworldspeakChinese.（主语people是谓语动词speak的发出者）。②主语是动作的接受者（承受者）为被动语态。如：Chineseisspokenbythemostpeopleintheworld.（主语Chinese是谓语动词speak的接受者）。③主动语态和被动语态的相互转换。Mygrandmotherwatersflowerseveryday.主语谓语宾语其他Flowersarewatered(bymygrandmother)everyday例：TodayChinese_______bymoreandmorepeoplearoundtheworld.A.isspokenB.speakC.speaks3.语态与时态的关系：在一个英语句子中都同时存在时态和语态，一般现在时和被动语态，即一般现在时的被动语态。如：Treesareplantedbyuseveryyear.我们每年都植树。被动语态的句型结构基本构成：am/is/are+及物动词的过去分词肯定句：主+am/is/are+及物动词的过去分词+其他.e.g.ThisbikeismadeinShanghai.否定句：主+am/is/are+not+及物动词的过去分词+其他.e.g.Thisbikeisn’tmadeinShanghai.一般疑问句：am/is/are+主+及物动词的过去分词+其他？e.g.IsthisbikemadeinShanghai?特殊疑问句：特殊疑问句+am/is/are+主+及物动词的过去分词+其他？e.g.Whatisthisbikemadeof?三．注意事项：【1】.不用被动语态的词：半系动词，happen,takeplace,sell+adv,cometrue等。如：1)

ThiskindofTVsetsellswell.这种电视卖得好。2)ThestoryhappenedinParisintheearlytwentiethcentury.

这个故事发生在二十世纪早期的巴黎。3)Greatchangeshavetakenplaceinourcountrytheseyears.这些年中国发生了巨大的变化。4)Thefoodsmellsterrible.这些食物闻起来难闻。2.注意短语中的介词或副词不能丢掉。如：1)Theoldshouldbetakengoodcareof.老人应该被好好照顾。

2)Allthelightshadbeenturnedoff

beforewelefttheclassroom.在我们离开教室之前，所有的灯都被熄灭了。【2】.make/have/see/watch/hearsb.do等使役动词主动形式中没有to,但是它们的被动形式要加to。如：bemadetodo,beseentodo,beheardtodoHewasseentogointothebuilding.
