1、人教版高中英语必修2 现在完成时的被动语态用法讲解(教师版)1/6【高一同步教程】高中英语必修2 现在完成时的被动语态用法讲解【学习目标】1现在完成时被动语态的结构2现在完成时被动语态的主要用法3使用现在完成时的被动语态需要注意的问题【课前预习】1什么是语态?语态是表示主语和动词之间的主动关系或被动关系的动词形式。英语动词有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者(施动者),被动语态表示主语是动作的承受者(受动者)。2对现在完成时被动语态的理解现在完成时被动语态的结构就是现在完成时态和被动语态结构的叠合,即“have+been+动词过去分词”。试比较以下几组句子的谓语结构:
2、1)主动句:He has repaired the machine for two hours.他修理这台机器已有两小时了。被动句:The machine has been repaired for two hours.这台机器已修了两小时了。2)主动句:The teacher has borrowed the books.老师把那些书借走了。被动句:The books have been borrowed by the teacher.那些书被老师借走了。【教学过程】一、现在完成时被动语态的构成1现在完成时被动语态的肯定式由“have has been 及物动词的过去分词”构成。例如:Two
3、 windows have been broken 两个窗子被打破了。2现在完成时被动语态的否定式由“have has notbeen 及物动词的过去分词”构成。例如:The car has not been repaired这辆汽车还没有修好。3现在完成时被动语态的一般疑问式由“HaveHas 主语 been及物动词的过去分词”构成。例如:Has her work been finished?她的工作完成了吗?Yes,it has是的,完成了。Have the cars been repaired?这些汽车修好了吗?No,they havent 不,还没有。4现在完成时被动语态的特殊疑问式由
4、“疑问词havehas主语 been及物动词的过去分词”构成。例如:How long has her work been finished?她的工作完成有多久了?Who has been helped by the new computer?谁已经得到了这台新计算机的帮助?How many new words have been learned by the students?这些学生已经学会了多少单词?二、现在完成时被动语态的主要用法1表示被动的动作发生在说话之前(即现在的过去),强调对现在造成的影响和结果。例如:The door has been locked门被锁上了。(结果是现在没有人
5、能进去)2表示一个被动的动作或状态开始于过去,持续到现在,并可能将持续下去,常与for 或 since 引导的时间状语连用,或用于How long?句型中。例如:名师资料总结-精品资料欢迎下载-名师精心整理-第 1 页,共 6 页 -人教版高中英语必修2 现在完成时的被动语态用法讲解(教师版)2/6 The old man has been looked after for twenty years.1 这位老人已受照顾20 年了。(可能还会被照顾下去)They have been told about it for many times 有人告诉他们这事很多次了。(可能还会有人告诉他们)Ho
6、w long has the machine been used?这机器使用有多久了?三、使用现在完成时的被动语态需要注意的问题1现在完成时的被动语态有两个助动词,即have has 和 been,两者缺一不可。2只带有一个宾语的动词变为被动语态时,将主动语态的宾语变为被动语态的主语。We have built many houses in the past ten years.Many houses have been built in the past ten years(by us).3带有双宾语的动词,如:give,send,bring,take,teach,show,sing,wri
7、te,read,sell,buy,tell,pay,lend,pass,promise 等,变为被动语态时,可将其中一个宾语变为主语,另一个保留不动。We have given him the book.He has been given the book.The book has been given to him.4带有复合宾语的动词变为被动语态时,只能将宾语变为主语,原来的宾补改为主语补足语。原来省略to 的不定式作宾补时,被动语态中要用带to 的不定式。I have told them to help you.They have been told to help you.I have
8、 made her work hard.She has been made to work hard(by me).5短语动词是一个不可分割的整体,在被动结构中要保持完整性,不可省略短语动词中的介词或副词。例如:The orphan has been well looked after 这位孤儿一直受到很好的照顾。They have referred to the books.The books have been referred to(by them).He has thought of a way of doing it.A way of doing it has been though
9、t of(by him).6由 finish,buy,start,begin,post,return,borrow,join,marry,open 等词构成的现在完成时的被动语态不能与表示一段时间的状语如for four days,how long 等连用,而要改换动词或时态。例如:译:这本书买了多久了?误:How long has this book been bought?正:How long ago was this book bought?但这类动词的否定式可表示动作的持续过程,具有延续性,因而可与since 或 for 引导的时间段连用。例如:No books have been b
10、ought since last week 自上周以来,没有人来买过书。7注意与一般过去时被动语态的区别。一般过去时的被动语态表示一个被动的动作发生在过去某个时刻,其结果对现在没有影响;而现在完成时被动语态的动作或状态尽管发生在过去,但侧重说明该动作或状态对现在造成的影响和结果。例如:The house was built last year 这房子是去年建造的。The house has been built这房子已经建好了。四、经典习题1.I cant see any coffee in this cupboard.(北京 2005 春)2 A.Has it all been finish
11、ed B.Was it all finished C.Has it all finished D.Did it all finish 名师资料总结-精品资料欢迎下载-名师精心整理-第 2 页,共 6 页 -人教版高中英语必修2 现在完成时的被动语态用法讲解(教师版)3/6 2.Millions of pounds worth of damage by a storm which swept across the north of England lastnight.(重庆2005)A.has been caused B.had been caused C.will be caused D.wi

13、影响和结果),所以紧接着要问“咖啡已经被喝完了吗?”,故选 A。第 2 题的意思是“昨晚横扫英格兰北部的暴风雨已经造成了上百万英镑的损失”,这里强调发生在过去的动作对现在造成的影响,故选A。第 3 题中的 patients 与 treat 之间是被动关系,排除A、B。根据时间状语this year 可知用现在完成时的被动语态,故选 D。第 4 题上句提到“窗户很脏”,所以下句应该是“窗户已经有数周没有被擦了”,故选 D。【课后练习】一、把下列句子变成被动语态1.Mary has locked the door.2.She has told me about the story.3.I have
