被动语态(Passive voice)讲解

By Rebecca

一、被动语态的基本时态变化

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/ be going to be done/ be about to be done一般将来时

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

8)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.

二、被动语态的特殊结构形式---主动表被动

1. 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.

2. 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).

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

6.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

三、语态转换时所注意的问题

1.含有双宾语的主动句变被动句时,可分别将其中的一个宾语变为主语,另一个不动,一般变间接宾语为主语时比较多。

My uncle gave me a present on my birthday.

I was given a present on my birthday.

如果把直接宾语(指物)改为主语,则在间接宾语(指人)前加适当的介词,如上句还可以说:

A present was given to me yesterday.

注意:①一般在下列动词后,常在间接宾语前用介词to,如:bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。

The book was showed to the class.

②一般在下列动词后,间接宾语前用介词for, 如:build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing 等。

A new skirt was made for me.

3. 由动词+ 介词或副词构成的短语动词,要把它们作为整体看,即把它们看成一个及物动词,介词或副词不可拆开或漏掉。这类动词有:

不及物动词+ 介词,如: agree to, ask for, laugh at, operate on, listen to, look after, think of, talk about 等。

The patient is being operated on.

The problem is solved. It needn't be talked about.

及物动词+ 副词:如:bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away, put off, think over, turn down, work out, turn out 等。

His request was turned down.

The sports meet will be put off because of the bad weather

4. 在see, watch, hear, notice, listen to, look at,make, feel等动词后作宾语补足语的动词不定式都不带to,但改成被动语态后都带to,这时不定式为主语补足语,也就是说不定式作主语补足语不存在省略to 的问题。

We often hear him play the guitar.

→He is often heard to play the guitar.

5. 在汉语中,有一类句子不出现主语,在英语中一般可用被动结构来表示,例如:

据说……It is said that …

据报导……It is reported that …

据推测……It is supposed that …

希望……It is hoped that …

众所周知……It is well known that …

普遍认为……It is generally considered that …

有人建议……It is suggested that …

1) It is reported that it is going to rain tomorrow.

2) It is well known that Thomas Edison invented the electric lamp.

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

初中英语动词的主动语态和被动语态讲解

动词的主动语态和被动语态【用法讲解】考试要求: 中考要求掌握:动词的主动语态和被动语态区别与使用,不同时态的被动语态形式及情态动词的被动语态形式。英语动词有两种语态:主动语态和被动语态,主动语态表示句子的主语是谓语动作的执行者;被动语态是表示句子的主语是谓语动作的承受者。 如:We often clean the blackboard.(我们是擦黑板的执行者即主动语态)The blackboard is often cleaned by us.(黑板是clean的承受者即被动语态)。 1.被动语态的结构 一般现在时:am / is / are +及物动词的过去分词 一般过去时:was / were +及物动词的过去分词 一般将来时:will / shall be +及物动词的过去分词 现在完成时:have / has been +及物动词的过去分词 现在进行时:am / is / are being +及物动词的过去分词 过去完成时:had been +及物动词的过去分词 如:Youare wantedon the phone.有你的电话。 Chinawas liberatedin 1949. 1949年中国解放。 The problemwill be discussedtomorrow. 明天将对这个问题进行讨论。 Not a book in the libraryhas been taken away. 图书馆里没有一本书被人拿走。 My bikeis being repaired.我的自行车正在修理。

The bookhad been borrowedwhen I got to the library.我到了图书馆时,那本书已经借出去了。 2.主动语态与被动语态的转换 (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。 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. He cut down a tree. →A tree was cut down by him. 3.含有情态动词的被动语态 含有情态动词的主动句变成被动句时,由“情态动词+be+过去分词”构成,原来带to的情态动词变成被动语态后“to”仍要保留。 We can repair this watch in two days. →This watch can be repaired in two days. They should do it at once. →It should be done at once. 4.含有双宾语的主动语态变为被动语态 主动语态:主语+谓语动词+间接、直接宾语+其他

A. keep;be lent B. borrow;lend C. lend;be borrowed D. have;borrow 【答案】 A 【解析】【分析】句意:—你的字典我能保存多长时间?—一周,但是你千万不要把它借给其他人。keep保存,保持,是延续性动词;borrow借,是瞬间性动词,不能和一段时间搭配使用;lend借给,瞬间性动词;have拥有。根据句意可知,第一句话中How long 表示一段时间,故B和C不对;第二句话表示借出,故D不对,选A。 【点评】此题考查短暂性动词和延续性动词的区别和情态动词的被动语态的用法。 2.Let's wait and see whether books by the Internet in the future. A. replace B. replaced C. will be replaced D. were replaced 【答案】 C 【解析】【分析】句意:让我们等着看是否将来书会被网络替代。whether引导的宾语从句根据时间确定时态,结合in the future可知表达的是将来的事情,主语books是动词replace的承受者,故用一般将来时的被动语态will+be+过去分词,故选C 【点评】考查一般将来时的被动语态。 3.It's not your turn yet.Please wait on the chair over there until you _______. A. are calling B. have called C. are called 【答案】 C 【解析】【分析】句意:现在还没有轮到你.请等在那边的椅子上,直到有人叫你。结合语境可知,主语you是动作call的承受者,因此这里用一般现在时态的被动语态,结构式is/are/am+动词的过去分词.主语是you,用be动词are.call的过去分词是called.答案是C 【点评】考查一般现在时的被动语态。 4.His car ____ five years ago, but it looks quite new. A. buys B. bought C. is bought D. was bought 【答案】 D 【解析】【分析】句意:他的车是五年前买的,但看起来很新。his car与动词buy由动宾关系,且his car做主语;由five years ago提示,谓语动词要用一般过去时的被动语态,故

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:

初中英语被动语态的讲解

初中英语被动语态的讲解 定义:英语中有两重语态:主动语态和被动语态。主动语态中的主语是动作的执行者,被动语态中的主语是动作的承受者,即主动语态中的宾语。所以只有及物动词才有被动语态。 规则:被动语态由“助动词be+及物动词的过去分词”构成。第一,助动词be 要随着人称和数的变化而变化,第二,助动词be 要随着时态的变化而变化。 一、被动语态的构成形式1. 被动语态的基本时态变化以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)was/were done 一般过去时例I was given ten minutes to decide whether I should reject the offer. 3)shall/will be done 一般将来时例Hundreds of jobs will be lost if the factory closes. 4)am/is /are being done 现在进行时例A new cinema is being built here. 5)was/were being done 过去进行时例A meeting was being held when I was there. 6)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. 7)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. 8)had been done 过去完成时例By the end of last year, another new gymnasium had been completed in Beijing. 9)shall/will have been done 将来完成时(少用)例The project will have been completed before July. 2.被动语态句型变化肯定句主语+be+过去分词,否定句主语+be not+过去分词,一般疑问句Be+主语+过去分词,特殊疑问句疑问词+be+主语+过去分词。 3.被动语态的特殊形式 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) 双宾语结构。主动结构中的一个宾语变为主语,另一宾语仍
