14、语态则表示主语是谓语动作的承受者。,一、被动语态的构成,1.被动语态是由助动词be加动词的过去分词构成的,如果要强调动作的执行者,动作执行者可以用介词by引出的短语表示。助动词be随主语的人称、数、时态和语气的不同而变化。,In the near future,more advances in the robot technology will be made by scientists. 在不久的将来,科学家在机器人技术方面将取得更多的进步。 This coastal area was named a national wildlife reserve by the government l

15、ast year. 这个沿海地区去年被政府确定为国家野生动物保护区。,2.被动语态的形式。,Traditional folk arts of Tianjin like paper cutting are being exhibited at the culture show. 像剪纸这样的天津传统民间艺术正在文化展示区展出。 All visitors to this village are treated with kindness. 所有到这个村的游客都受到了善意的对待。 After getting lost in a storm,a member of the navy team was

16、rescued four days later. 迷失在暴风雨中四天后,一名海军成员被救起。 Experiments of this kind had been conducted in both the U.S.and Europe well before the Second World War. 早在第二次世界大战之前这种实验在欧洲和美国就进行过。 How many expressways will have been completed by the end of next year? 到明年年底将建成多少条高速公路?,二、被动语态的用法,1.不知道谁是动作的执行者或没有必要说出谁是执

17、行者。,Scientists say that work is done whenever a force moves. 科学家们说,力移动时就做了功。,2.需要强调或突出动作的承受者。,A new Hope School will be opened in our village. 我们村将开办一所新的希望学校。(强调a new Hope School) Books and newspapers in the reading room mustnt be taken away. 阅览室里的书和报纸禁止被拿走。 (强调books and newspapers),3.为了使语气委婉,避免提及自己

18、或对方而使用被动语态,或由于修饰的需要,使用被动语态,使句子得到更好的安排。,The construction of the new lab must be completed by the end of next month. 新实验室的建设必须在下个月月底前完成。 Youve been told many times not to make the same mistake. 你已经被多次告知不要犯同样的错误。,三、主动语态与被动语态互换,1.主语谓语宾语。,“主语谓语宾语”结构中只有一个宾语,变为被动语态时,将宾语变为主语。 They will discuss the plan at t

19、he meeting. The plan will be discussed at the meeting by them. 他们将在会议上讨论这个计划。,2.主语谓语间接宾语直接宾语。,在这个句型中,谓语动词后跟两个宾语。变成被动语态时,一般将通常指人的间接宾语转化成主语,但有时也可将指物的直接宾语转化成主语。 His father bought him a computer last week. He was bought a computer by his father last week. 上周他父亲给他买了一台电脑。,3.主动语态变为被动语态的几种特殊情况。,(1)在使役动词have

20、,make,get以及感官动词see,watch,notice,hear,feel,observe等后面不定式作宾语补足语时,在主动结构中不定式to要省略,但变为被动语态时,要加to。 My grandfather was made to work for 10 hours a day. 我的爷爷一天要工作十个小时。 (2)含有宾语从句的主动语态变为被动语态时,通常用it作为被动结构的形式主语,从句放在句子后面,这类动词有:know,say,believe,find,think,report等。 It is said that part of the aircraft wing found o

21、n Reunion Island is from the missing MH370 plane. 据说在留尼汪岛被找到的部分机翼是来自失联的MH370的。,Its well-known that Sichuan Province provides a perfect natural habitat for pandas. 众所周知,四川省是熊猫最佳的天然栖息地。 (3)有些动词虽为及物动词,但宾语并非动作承受者,不能转换,这些动词有have,hold(容纳),suit,fit,lack,contain,cost,last,mean等。 The hall can hold 500 people

22、. 这个大厅能容纳500人。 The book contains six chapters. 这本书包含六章。,四、主动形式表被动意义的情况,1.一些表示感官意义的连系动词,如taste(品尝起来),sound(听起来),feel(摸起来),smell(闻起来),prove,turn,grow,fall,keep等,后接形容词或名词构成系表结构。,The flower smells sweet.这朵花闻起来香。 Good medicine tastes bitter.良药苦口。,2.一些不及物动词,如open,close,shut,lock,move,read,write,wash,sell,

23、clean,cook,burn,draw,cut,wear,begin,start,finish,end,keep等,表示主语的某种属性、特征或所处状态(常与easily,quickly,well等副词连用),而非强调动作本身时,通常用主动形式表示被动意义。,The table cant move.这桌子移不动。 The door locks easily.这门容易锁上。,3.在“be形容词to do”结构中,不定式在作表语的形容词后充当状语,同时,主语是不定式结构的逻辑宾语,此时习惯上以主动形式表示被动意义。这些形容词通常有difficult,hard,cheap,expensive,eno

24、ugh,sure,fit,nice,dangerous,comfortable,exciting,good,important等。,The text is easy to understand.这篇课文容易理解。,4.在need(want,require,deserve,etc.)doing句型中,动名词doing相当于动词不定式的被动式to be done,在意思上没有多大差别。,Our classroom wants/needs/requires cleaning. Our classroom wants/needs/requires to be cleaned. 我们的教室需要打扫。,五

25、、被动结构和系表结构的区别,1.被动语态中的过去分词是动词,多强调动作;系表结构中的过去分词相当于形容词,多强调状态。前者通常可用by人或by抽象名词表动作的执行者,而后者则一般不用。,The tree was blown down by the strong winds. 那棵树被强风吹倒了。(被动结构) The tree was blown down when we saw it. 我们看到那棵树时,它已经被吹倒了。(系表结构),2.系表结构一般只用于一般现在时、一般过去时等几种时态,而被动语态可用于多种时态。,The composition is well written. 这篇作文写得

26、很好。(系表结构) The composition is being written. 这篇作文正在被写。(被动语态),学法点拨 巧记被动语态,被动语态强调“宾”,用be加上“过去分”。 “be”要随着主语变,人称时态要弄准。 “行为对象”作主语,逻辑主语“by”来引。 原句若有双宾语,一变“主”来一保“宾”。 “间宾”要把主语变,原来“直宾”还是“宾”。 “直宾”要把主语变,“间宾”前加“to”最称心。 原句“宾补”变“主补”,位置不必挪寸分。 情态动词变“被动”,情态加be加过分。 “短语动词”变“被动”,相当“及物”莫疑心。 不过其后“介”或“副”,变后还是要承认。,.用所给词的适当形式

27、填空 1.Its said that the long bridge _(build)in two months. 2.Where to have the meeting _(discuss)now. 3.Which language _ the most widely _(speak)in the world? 4.The lost boy hasnt _(find)so far. 5.Last year a large number of trees _(cut)down. 6.The students _ often _(tell)to take care of their desks

34、fforts之间为被动关系,所以用一般将来时的被动语态。故选D。 答案 D,3.To my delight,I _ from hundreds of applicants to attend the opening ceremony.,A.was chosen B.was being chosen C.would choose D.had chosen 解析 句意:令我高兴的是,在几百个申请者中我被选中参加开幕式了。首先,句子主语I和choose是被动关系,所以要用被动语态;其次,本句是对过去所发生事情的客观描述,所以用一般过去时。 答案 A,4.My washing machine _ th
