2017年中考英语《被动语态》复习课件.ppt

语法-被动语态,教 学 目 标,基 础 知 识,一、被动语态概述语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：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。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。汉语往往用“被”、“受”、“给”等词来表示被动意义,2.被动语态的构成：被字句：主语+be+动词过去分词(v-ed)+by sb.我打他 I beat him.(打过了)他被我打He was beaten by me.他喜欢她 He likes her.她被他喜欢She is liked by him.(am/is/are).,被动语态的时态是由be动词的时态决定的，be动词是什么时态，全句就是什么时态，be动词后面的过去分词不变。,主动语态变被动语态的方法：,We speak English.（主动语态）主语 谓语 宾语 English is spoken by us.（被动语态）主语 谓语 宾语宾变主，主变宾，前加by动变被，看清be，结构分别be+pp,1,2,3,主动语态be的谓语形式总结(1),主+am/is/are主+am/is/are+being主+will+be主+has been,He is a leader.He is being here.He will be a leader.He has been a leader.,主动语态be的谓语形式总结(2),主+was/were主+was/were+being主+would+be主+had been,He was a leader.He was being here just now.He would be a leader.He had been a leader several years ago.,各种时态被动语态的结构:,一般现在时:is/am/are done一般将来时：will be done现在进行时：is/am/are being done现在完成时：have/has been done一般过去时：was/were done过去将来时：would/should be done过去进行时：was/were being done过去完成时：had been done含情态动词的：情态动词+be+done,被动语态:主+be+过去分词+(by sb),1.He eats the apple.2.He ate the apple.3.He is eating the apple.4.He was eating the apple.5.He will eat the apple.6.He would eat the apple.7.He has eaten the apple.8.He had eaten the apple.,1.The apple is eaten by him.2.The apple was eaten by him.3.The apple is being eaten by him.4.The apple was being eaten by him.5.The apple will be eaten by him.6.The apple would be eaten by him.7.The apple has been eaten by him.8.The apple had been eaten by him.,三、情态动词的被动语态,他儿子一定照顾这个人。His son must take care of the person.这个人一定要由他儿子照顾=即这个人一定照顾由他儿子。The person must be taken care of by his son.含有情态动词的句子变为被动语态时，在情态动词后面直接加上be动词即可。构成：主语+情态动词(can,may,must)+be(永远是原形)+过去分词+by sb.,1.You must do this as soon as possible.2.I can use it.3.You should buy a dictionary.4.They need look after the little child.5.We can change water into ice.,1.This must be done as soon as possible(by you).2.It can be used.3.A dictionary should be bought(by you).4.The little child need be looked after(by them).5.Water can be changed into ice.,没有被动语态的几种情况(1).所有的不及物动词或不及物动词词组不能用于被动语态之中。这类动词或短语如：take place(发生)，happen(发生)，die,end(vi.结束),fail,lie,come truee.g:The story happened in 1990.e.g:His dream has come true.e.g:Great changes have taken place in our hometown during the past ten years.,(2)系动词无被动语态：be,become,fall,feel,get,grow,keep,look,seem,smell,sound,taste,The piece of music sounds good.听起来很好。The cake tastes delicious.,被动语态中几个要注意的问题：1、使役动词和感官动词的被动语态在主动语态中，使役动词和感官动词后都是接动词原形，而在被动语态中需接动词不定式。e.g:The great news made her feel happy.she was made to feel happy by the great news.I heard her sing in her room a few minutes ago.She was heard to sing in her room a few minutes ago.,2、含有双宾语的动词在变为被动语态,有些双宾动词(如buy,give,leave,lend,offer,pay,show,teach,tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词有关)。比较：He gave her some money.他给她一些钱。She was given some money.Some money was given to him.He bought her a watch.他给她买了一快表。A watch was bought for her.She was bought a watch.,3、一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。,He listens to the radio every day.The radio is listened to by him every day.The nurse is taking care of the sick man.The sick man is being taken care of by the nurse.,基础练习题,()1.The Peoples Republic of China _ on October 1,1949.A.found B.was founded C.is founded D.was found()2.English _ in Canada.A.speaks B.are spoken C.is speaking D.is
