Mars.,现在完成时的被动语态表示动作发生在过去,到现在已经完成或对现在仍有影响。,现在完成时的被动语态,Understanding the structure of the present perfect passive voice,The structure of the present perfect passive voice is:,have/has+been+ed,主动语态即主语为动作的执行者；被,动语态即主语为动作的承受者。现在完,成时的被动语态同它的主动语态一样，,强调过去的动作对现在造成的影响或结,果，但主语为动作的承受者，表示“,已经被,”,。,The new school,has been set up,.,新学校已经建成了。,2.,现在完成时被动语态的肯定式为：,have/has+been+done,The experiment,has been done,successfully.,这个实验做得很成功。,现在完成时被动语态的否定式为：,have/has+not+been+done,Toms novel,has not been published,.,汤姆的小说还没有被出版。,现在完成时被动语态的一般疑问句需将,have/has,提到主语的前面。,Has,his bike,been repaired,?,他的自行车修好了吗？,现在完成时被动语态的特殊疑问句为：,疑问词,+have/has+been+done,Who,has been invited,?,谁受到了邀请？,现在完成时的被动语态表达以下两个,概念：,1.,说话时已经完成的动作或出现的结果。,2.,主语是行为动作的承受者。,现在完成时的被动语态由,have/has been,+v-ed,构成，其中,v-ed,为过去分词，,表示被动。,I,have been told,about it many times.,The bridge,has,just,been built,.,在使用现在完成时的被动语态时要,注意以下两点：,1.,过去分词前有两个助动词：,have/has,和,been,。,2.,必须表示被动。,注意,:,副词的位置,often,usually,always,never,hardly,seldom,等副词置于,have/has,和,been,中,间。如,:,误,Such a man has been hardly,believed.,正,Such a man has,hardly,been,believed.,2.,并不是所有动词都有被动语态,happen,take place,break out,belong,to,cost,last,等不及物动词或词组无被,动语态。如：,误,Great changes have been taken,place in China since 1978.,正,Great changes have,taken place,in China since 1978.,(2)open,break,drop,等不强调动作发出,者时常用主动语态。,3.,短语动词不可分割或省略其中的介词,或副词。如：,The patients,have been taken good care,of,.,(1),把主动语态的宾语变为被动语态的主语。,(2),把谓语变成被动结构,(be+,过去分词,),(,根据被动语态句子里的主语的人称和数，以及原来主动语态句子中动词的时态来决定,be,的形式,),。,主动语态变被动语态的方法,(3),把主动语态中的主语放在介词,by,之,后作宾语，将主格改为宾格。,All the people laughed at him.,He was laughed at by all the people.,They make the bikes in the factory.,The bikes are made by them in the,factory.,(4),双宾语动词变被动语态可将其中的一,个宾语变为主语，另一个保留不动。,主动：,I have given him the key.,被动：,He has been given the key.,被动：,The key has been given(to)him.,(5),带复合宾语的动词变被动语态时，只,能将宾语变为主语，原来的宾补保留,不动，改称主语补足语。,主动：,I have asked her to help you.,被动：,She has been asked to help you.,(1),误,Many new buildings been built,since 1980.,正,Many new buildings have been,built since 1980.,分析,:,谓语部分结构不全,时态部分不完整。,试分析：,(2),误,Something bad has been,happened to him.,正,Something bad has happened to,him.,分析,:,被动语态误用。,happen,为不及物动,词，不及物动词没有被动语态。,(3),误,I have introduced to Mr.Smith.,正,I have been introduced to Mr.,Smith(by Mr.Wang).,分析,:introduce,为及物动词，,I,是,introduce,的承受者。,(4),误,The door has been opened of,itself.,正,The door has opened of itself.,分析,:,有些动词如,open,，,break,，,drop,等既可以作及物动词，又可以作不及物动词，若不强调谁是动作的发出者，我们通常用主动语态。,of itself,意思是“自动地”，因此，此句不可用被动语态。,Review,现在完成时的被动语态,肯定结构：,have/has+been+done,否定结构：,have/has+not+been+done,Individual activity,注,:,另附,word,文档。,点击此处链接,1.When and where to go for the on-,salary holiday _
