被动语态讲解

一、被动语态的构成形式

1. 被动语态的基本时态变化

被动语态通常为十种时态的被动形式, 被动语态由be+过去分词构成,be 随时态的变化而变化。以do为例,各种时态的被动语态形式为:

1) am/is/are +done (过去分词) 一般现在时

例Visitors are requested not to touch the exhibits.

2)has /have been done 现在完成时

例All the preparations for the task have been completed, and we're ready to start.

3)am/is /are being done 现在进行时

例A new cinema is being built here.

4)was/were done 一般过去时

例I was given ten minutes to decide whether I should reject the offer.

5)had been done 过去完成时

例By the end of last year, another new gymnasium had been completed in Beijing.

6)was/were being done 过去进行时

例A meeting was being held when I was there.

7)shall/will be done 一般将来时

例Hundreds of jobs will be lost if the factory closes.

8)should/would be done 过去将来时

例The news would be sent to the soldier's mother as soon as it arrived.

9)shall/will have been done 将来完成时(少用)

例The project will have been completed before July.

2. 被动语态的特殊结构形式

1)带情态动词的被动结构。其形式为:情态动词+be+过去分词。

例The baby should be taken good care of by the baby-sitter.

2) 有些动词可以有两个宾语,在用于被动结构时,可以把主动结构中的一

个宾语变为主语,另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。

例His mother gave him a present for his birthday. 可改为He was given a

present by his mother for his birthday.

3) 当“动词+宾语+宾语补足语”结构变为被动语态时,将宾语变为被动结构中的主语,其余不动。

例Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.

4)在使役动词have, make, get以及感官动词see, watch, notice, hear, feel, observe等后面不定式作宾语补语时,在主动结构中不定式to要省略,但变为被动结构时,要加to。

例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building.

5) 有些相当于及物动词的动词词组,如“动词+介词”,“动词+副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开。其中的介词或副词也不能省略。

例The meeting is to be put off till Friday.

3. 非谓语动词的被动语态

v.+ing 形式及不定式to do 也有被动语态(一般时态和完成时态) 。

例I don't like being laughed at in the public.

二、如何使用被动语态

学习被动语态时,不仅要知道被动语态的各种语法结构,还要知道在哪些情况中使用被动语态。

1. 讲话者不知道动作的执行者或不必说出动作的执行者(这时可省by 短语)。

例My bike was stolen last night.

2. 借助被动的动作突出动作的执行者。

例I was given ten minutes to decide whether I should accept the offer.

3. 为了更好地安排句子。

例The well-known person got on the bus and was immediately recognized by people. (一个主语就够了)

三、It is said that+从句及其他类似句型

一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It+be+过去分词+that从句”或“主语+be+过去分词+to do s th.”。有:

It is said that… 据说,It is reported that…据报道,It is believed that…大家相信,It is hoped that…大家希望,It is well known that…众所周知,It is thought that…大家认为,It is suggested that…据建议。

例It is said that the boy has passed the national exam. (=The boy is said to have passed the national exam. )

四、谓语动词的主动形式表示被动意义

1.英语中有很多动词如break,catch,clean,drive,lock,open,sell,read,write,wash等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表达被动意义,主语通常是物。

例This kind of cloth washes well.

注意:主动语态表被动强调的是主语的特征,而被动语态则强调外界作用造成的影响。

试比较:The door won't lock.(指门本身有毛病)

The door won't be locked.(指不会有人来锁门, 指“门没有锁”是人的原因)

2. 表示“发生、进行”的不及物动词和短语,如:happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。

例How do the newspapers come out? 这些报纸是如何引出来的呢?

3. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式表示被动意义。

例Your reason sounds reasonable

五、非谓语动词的主动形式表被动意义

在某些句型中可用动名词和不定式的主动形式表被动意义。

1.在need,want,require, bear等词的后面,动名词用主动形式表示被动意义,其含义相当于动词不定式的被动形式。

例The house needs repairing(to be repaired).这房子需要修理。

2.形容词worth后面跟动名词的主动形式表示被动含义,但不能跟动词不定式;而worthy后面跟动词不定式的被动形式。

例The picture-book is well worth reading.(=The picture-book is very worthy to be read.)

3. 动词不定式在名词后面作定语,不定式和名词之间有动宾关系时,又和句中另一名词或代词构成主谓关系, 不定式的主动形式表示被动含义。

例I have a lot of things to do this afternoon.(to do与things是动宾关系,与I是主谓关系。)

试比较:I’ll go to the post office. Do you have a letter to be posted? ( 此处用不定式的被动语态作定语表明you不是post动作的执行者。)

4. 在某些“形容词+不定式”做表语或宾语补足语的结构中,句子的主语或宾语又是动词不定式的逻辑宾语时,这时常用不定式的主动形式表达被动意义。这些形容词有nice,easy,fit,hard,difficult,important,impossible,pleasant,interesting等。

例This problem is difficult to work out .(可看作to work out省略了for me).

5.在too… to…结构中,不定式前面可加逻辑主语,所以应用主动形式表示被动意义。

例This book is too expensive (for me) to buy.

6. 在there be…句型中,当动词不定式修饰名词作定语时,不定式用主动式作定语,重点在人,用被动形式作定语,重点在物。

例There is no time to lose(to be lost).(用to lose可看成for us to lose;用to be lost,谁lost time不明确。)

7. 在be to do结构中的一些不定式通常应用主动表主动, 被动表被动。然而,由于古英语的影响,下列动词rent,blame,let等仍用不定式的主动形式表示被动意义。

例Who is to blame for starting the fire?

六、介词in, on, under等+名词构成介词短语表被动意义

表示方位的介词与含动作意义的名词合用,含被动之义,其意义相当于该名词相应动词的被动形式,名词前一般不用冠词。

1. “under +名词”结构,表示“某事在进行中”。常见的有:under control(受控制), under treatment(在治疗中), under repair(在修理中), under discussion (在讨论中), under construction(在施工中)。

例The building is under construction( is being constructed).

2.“beyond+名词”结构,“出乎……胜过……、范围、限度”。常见的有:beyond belief (令人难以置信),beyond one’s reach(鞭长莫及),beyond one’s control (无法控制),beyond our hope.我们的成功始料不及。

例The rumour is beyond belief(=can’t be believed).

3.“above+名词”结构, 表示“(品质、行为、能力等) 超过……、高于……”。

例His honest character is above all praise.=His honest character cannot be praised enough.

4.“for+名词”结构,表示“适于……、为着……”。如:for sale(出售), for rent (出租)等。

例That house is for sale. (= That house is to be sold).

5.“in+名词”结构,表示“在……过程中或范围内”常见的有:in print(在印刷中),in sight(在视野范围内),等。

例The book is not yet in print.(=is not yet printed)

6.“on+名词”结构, 表示“在从事…… 中”。常见的有:on sale(出售),on show (展出), on trial(受审)。

例Today some treasures are on show in the museum (= are being showed).

7.“out of+名词”结构;表示“超出…… 之外“,常见的有:out of control (控制不了),out of sight (超出视线之外),out of one’s reach(够不着), out of fashion(不流行)等。

例The plane was out of control (can’t be controlled).。

8.“within+名词”结构,“在……内、不超过……”。

例He took two days off within the teacher's permission.

英语被动语态讲解及练习

英语被动语态讲解及练习 一、什么是被动语态? 英语中时态很多,但语态不多,只有两种,即:主动语态和被动语态。所谓“被动语态”,相当于中文中常说的“被……”、“由……”的句式,如:“他的自行车被偷了。”,“这座楼房是由他们建造的。” 二、被动语态的结构 那么,英语中被动语态是怎么样构成的呢?请看下面的例句(注意划线部分): His bicycle was stolen. The building has been built in 2000. 通过上面的例句,可以看出,“被动语态”的构成是: be + 过去分词+ (by+动作执行者) 三、被动语态的运用 什么情况下要用被动语态呢?一般地说,有下面几种情况: (1)不知道谁是动作的执行者或没有必要。例如: Paper is made from wood. (纸是由木材生产出来的。) The house is quite old. It was built in 1950. (这座房子太旧了。它是1950年建成的。) He was wounded in the fight. (他在战斗在受伤了。) Electricity is used to run machines. (电是用来开动机器的。) (2)需要强调动作的对象时。例如: Calculator can't be used in the maths exam.

(计算器不能用于数学考试。) Books and newspapers in the reading room mustn’t be taken away. (阅览室的书籍和报纸不准带走。) He was awarded first prize in that contest. (他在比赛中获得了第一。) (3)为了使语气婉转,避免提到是谁做的这件事。例如: The construction of the new lab must be completed by the end of next month. (新实验室必须在下个月底前完工。) 四、各种时态的被动语态举例 一般地讲,被动语态可用于英语的各种时态。为了能准确地运用被动语态,重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下: 1、一般现在时的被动语态. am / is / are + 动词的过去分词 Our classroom is cleaned every day. This car is made in China. 2、一般过去式的被动语态: was / were + 动词的过去分词 His desk was cleaned just now. The station was built in 1928. 3、现在进行时的被动语态: am / is / are + being + 动词的过去分词 A new factory is being built in our city now. Some trees are being cut down in the park. 4、过去进行时的被动语态: was / were + being + 动词的过去分词

初中被动语态详细讲解.

语法专练---被动语态 一、语态概述 我吃了一个苹果,那现在苹果怎样了?苹果被我吃了。正如汉语中的被字句,英语中的“被字句”我们称之为被动语态。英语中有两种语态:主动语态和被动语态。英语的语态是通过动词形式的变化表现出来的。 主动语态表示主语是动作的执行者。巧记为:主动、主动、主去动。例如:Many people speak English. 谓语:speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者,即行为动作的对象。巧记为:被动、被动、主被动。例如:English is spoken by many people.主语English是动词speak的承受者。 例如:He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句) 二、被动语态的构成 被动语态由“be+及物动词的过去分词”构成。不及物动词本身没有被动语态。 及物动词---本身意义不完整,后必须带宾语,有些还可以带双宾。 不及物动词---本身意义完整,不需要带宾语,如带宾语必须通过介词。 人称、数和时态的变化是通过be的变化表现出来的。现以eat为例说明被动语态在各种时态中的构成。 一般现在时:am/is/are+eaten 一般过去时:was/were+eaten 一般将来时:will/shall/be going to be+eaten 过去将来时:would/should/be going to be+eaten 现在进行时:am/is/are being+eaten 过去进行时:was/were being+eaten 现在完成时:have/has been+eaten 过去完成时:had been+eaten 歌诀是:被动语态be字变,过去分词跟后面。 三、被动语态的用法 (1)不知道或没有必要说明动作的执行者是谁。 例如:some new computers were stolen last night. 一些新电脑在昨晚被盗了。(不知道电脑是谁偷的) This book was published in 1981.这本书出版于1981年。(没有必要或说出出版者) (2)强调动作的承受者,而不强调动作的执行者。 例如:The window was broken by mike.窗户是迈克打破的。 This book was written by Lunxun.这本书是他写的。 Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证。 歌诀:谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。 (3) 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. (一个主语就够了) 四、主动语态变被动语态的方法 (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)。 (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。例如: All the people laughed at him. ---- He was laughed at by all people. They make the bikes in the factory. ----The bikes are made by them in the factory. 歌诀是:宾变主,主变宾,by短语后面跟。谓语动词变被动,be后“过分”来使用。 五、含有情态动词的被动语态

英语被动语态讲解及习题

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,被动语态表示主语是动作的承受者。如: Many people speak English.(主动语态) English is spoken by many people.(被动语态) 1.被动语态的构成 由于不及物动词不能带宾语,故无被动语态,只有及物动词或相当于及物动词的动词短语才有被动语态,其基本构成方式是“助动词be+过去分词”。 注意:“be+过去分词”结构不一定都是被动语态,有些动词(如be,feel,look,seem等)后面的过去分词已转化为形容词,用作表语表示状态。如: My bike is broken.(我的自行车坏了。) The door is open.(门开了。) 2.主动语态改被动语态的方法 1)将主动语态改为被动语态应注意以下三个方面:①将主动语态的宾语改为被动语态的主语;②将主动语态的谓语动词改为“be+过去分词”结构;③将主动语态的主语改为介词by之后的宾语,放在谓语动词之后(有时可省略)。 2)含直接宾语和间接宾语的主动语态改为被动语态时有两种情况:①把间接宾语改为被动语态的主语,直接宾语仍保留原位;②把直接宾语改为主动语态的主语,此时,间接宾语前要加介词to或for。如:He gave the boy an apple.→The boy was given an apple.(或An apple was given to the boy.) Her father bought her a present.→She was bought a present by her father.(或A present was bought for her by her father.) 3)不带to的动词不定式作宾语补足语的主动语态,改为被动语态时不定式前要加to。如: They watched the children sing that morning.→The children were watched to sing that morning. 4)带复合宾语的动词在改为被动语态时,一般把主动语态的宾语改为主语,宾语补足语在被动语态中作主语补足语。如: We call him Xiao Wang.→He is called Xiao Wang. He cut his hair short.→His hair was cut short. They told him to help me.→He was told to help me. 5)短语动词是不可分割的整体,改为被动语态时要保持其完整性,介词或副词不可遗漏。如: We must take good care of the young trees.→The young trees must be taken good care of. 6)含有宾语从句的主动结构变为被动结构时,通常用it作为被动结构的先行主语,从句放在句子后面;也可采用另一种形式。可以这样转换为被动结构的动词有know,say,believe,find,think,report等。如: People believe that he is ill.→It is believed that he is ill.(或:He is believed to be ill.) 3.被动语态改为主动语态的方法: 被动语态中介词by后的宾语改为主动语态中的主语(或按题意要求确定主语),按照这个主语的人称和数以及原来的时态把谓语动词形式由被动语态改为主动语态。注意在主动语态中有的动词要求不带to 的动词不定式作宾语补足语,此时要把被动语态中的to去掉。被动语态的主语用来作主动语态的宾语。如: History is made by the people.The people make history. 4.不能用于被动语态的情况 1)某些表示“静态”的及物动词(表示状态而不是动作,而且常常是不可用于进行时态的动词)如have,fit,suit,hold(容纳),cost,suffer,last(持续)等不能用于被动语态。如: They have a nice car.他们有一辆漂亮的汽车。 My shoes don't fit me.我的鞋不合适。 My brain can't hold so much information at one time.我的脑子一下子记不住这么多资料。 How much/What does it cost这值多少钱 Our holiday lasts 10days.我们的假期有十天。 This food will last(them)(for)3days.这食物足够(他们)(吃)三天。 2)不是所有带介词的动词都能用于被动结构。若是构成成语动词通常有被动态,若不构成成语动词则无被动态。试比较:

初中被动语态详细讲解上课讲义

初中被动语态详细讲 解

语法专练---被动语态 一、语态概述 我吃了一个苹果,那现在苹果怎样了?苹果被我吃了。正如汉语中的被字句,英语中的“被 字句”我们称之为被动语态。英语中有两种语态:主动语态和被动语态。英语的语态是通过动词形 式的变化表现出来的。 主动语态表示主语是动作的执行者。巧记为:主动、主动、主去动。例如:Many people speak English. 谓语:speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者,即行为动作的对象。巧记为:被动、被动、主被动。例 如:English is spoken by many people.主语English是动词speak的承受者。 例如:He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句) 二、被动语态的构成 被动语态由“be+及物动词的过去分词”构成。不及物动词本身没有被动语态。 及物动词---本身意义不完整,后必须带宾语,有些还可以带双宾。 不及物动词---本身意义完整,不需要带宾语,如带宾语必须通过介词。 人称、数和时态的变化是通过be的变化表现出来的。现以eat为例说明被动语态在各种时态中的 构成。 一般现在时:am/is/are+eaten 一般过去时:was/were+eaten 一般将来时:will/shall/be going to be+eaten 过去将来时:would/should/be going to be+eaten 现在进行时:am/is/are being+eaten 过去进行时:was/were being+eaten 现在完成时:have/has been+eaten 过去完成时:had been+eaten 歌诀是:被动语态be字变,过去分词跟后面。 三、被动语态的用法 (1)不知道或没有必要说明动作的执行者是谁。 例如:some new computers were stolen last night. 一些新电脑在昨晚被盗了。(不知道电 脑是谁偷的) This book was published in 1981.这本书出版于1981年。(没有必要或说出出版者) (2)强调动作的承受者,而不强调动作的执行者。 例如:The window was broken by mike.窗户是迈克打破的。 This book was written by Lunxun.这本书是他写的。 Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保 证。 歌诀:谁做的动作不知道,说出谁做的没有必要;动作承受者需强调,被动语态运用到。 (3) 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. (一个主语 就够了) 四、主动语态变被动语态的方法 (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)。
