英语被动语态与主动语态的区别
被动语态:
(1)被动语态定义:被动语态是动词的一种特殊形式,用来说明主语与谓语动词之间的关系。如果主语是 动作的执行者(即某人做某事),便叫主动语态;如果主语是动作的承受者(即某事被做),便叫被动语态。主动与被动的区别不是词序的区别,而是主语与谓语意义上的区别。在英语中只有及物动词和一些相当于及物动词的词组才有被动语态的形式。
(2)英语中被动语态由“助动词be +动词的过去分词”构成。助动词be有时态、人称和数的变化。被动语态后的by短语有时可省去。具体结构见下表:
现在时态 一般现在时 现在进行时 一 般 将 来 时 现在完成时
谓语动词构 成 am
is +p.p.
are am
is +being+p.p.
are will + be+p.p.
am
is +going to+ be + p.p.
are have(has) +been+p.p.
过去时态 一般过去时 过 去 进 行 时 过 去 将 来 时 过去完成时
谓语动词构 成 was +p.p.
were was
+being+p.p.
were would +be+p.p.
was +going to+be+p.p.
were had +been+p.p.
[注] p.p.表示过去分词。
(1) 被动语态的用法:
① 不知道谁是动作的执行者(即不知道谁做)时用被动语态,省略by短语。如:A man was killed in the accident.(一个人死于事故)/ This window was broken yesterday.(这扇窗子是昨天被打破的)
②不说或者众所周知是谁做时,用被动语态,省略by短语。如:Rice is also grown in this place.(这个地方也种水稻)/ A railroad will be built here in three years.(三年之后这里将要修建一条铁路)
③强调动作的承受者,句尾加by短语。如:It was written by Lu Xun.(它(书)是鲁迅写的)/ A pet dog is never killed by its owner.(宠物狗是不会被主人宰杀的)
(2) 主动语态如何改写为被动语态:
主动句: 主语(人/物) + 谓语(及物动词) + 宾语(人/物) + 其他 + 状语
(动作的执行者) (各种时态形式) (动作的承受者)
被动句: 主语(人/物) + 谓语(及物动词) + by +人 / 物 + 其他 + 状语
(动作的承受者) (be +过去分词) (动作的执行者)
(3) 注意点:
①“动词+间接宾语+直接宾语”改为被动时,可以用间接宾语做被动句的主语。如:
His teacher gave him a dictionary.→He was given a dictionary by his teacher.(老师给他一本字典→他得到老师一本字典)
也可以用直接宾语做被动句的主语,但是需用to或者for引出原句的间接宾语。如:His teacher gave him a dictionary.→A dictionary was given to him by his teacher.(老师给他一本字典→一本字典由老师送给了他)/His father made him a kite.→A kite was made for him by his father.(他的父亲给他做了一个风筝→一个风筝由他的父亲做给了他)
②“动词+宾语+动词原形”改为被动时,动词原形前要加to.如:The boss made the poor man work 12 hours a day.→The poor man was made to work 12 hours a day.(老板让这个可怜的人一天工作12小时→这个可怜人被迫一天工作12小时)
③“动词+…+介词”改为被动时,介词一般在原位不动。如:The girl takes good care of her little brother.→The girl’s little brother is taken good care of by her.(女孩照顾小弟弟→女孩的小弟弟由她照顾着)
④“be+过去分词”未必表示被动语态,而可能是系表结构。如:
He is pleased / worried / tired /…….(系表)(他高兴/焦虑/疲劳……)
He was hit / knocked down / told / shot / …….(被动)(他被击中/撞倒/关照/射中……
英语被动语态的结构
英语被动语态的结构
被动语态的句子是以《be动词+过去分词》的形式来表达,如果要特别强调动作或行为的执行者时,句子后面需接by,译为“被(由)……”。
1 被动语态的句型
肯定句:主语+be +过去分词+(by~).
否定句:主语+be not +过去分词+(by~).
一般疑问句:Be +主语+过去分词+(by~)?
特殊疑问句:疑问词+be +主语+过去分词+(by~)?
被动语态的时态是由be的时态决定的,be是什么时态,全句就是什么时态,be动词后面的过去分词不变。
2 被动语态的十种时态
以动词give为例,其被动语态的.各种时态构成如下:
1.一般现在时
History is made by the people.
历史是人民创造的。
2.一般过去时
These new cars were made in Tianjing in 1994.
这些新车是1994年在天津生产的。
3.一般将来时
Li Ming will be asked to attend the lecture.
李明将被邀请参加讲座。
4.现在进行时
A new railway is being built.
一条新铁路正在修建。
5.过去进行时
The roads were being widened.
路那时正在加宽。
6.现在完成时
He has been sent to work in Shanghai.
他已经被派往去上海工作了。
7.过去完成时
A new hotel had been built when I got there.
我到那儿时,一座新旅馆已经建好了。
8.过去将来时
He said a new hotel would be built in two months.
他说两个月后新旅馆就会建好了的。
3 被动语态的否定句和疑问句
English is not used in European countries.
欧洲国家不使用英语。
Is English used in European countries?
欧洲国家使用英语吗?
1.否定句
凡是有be动词的句子,其否定句都是在be动词的后面加not,被动语态也不例外。
This song is not liked by young people.
这支歌不被年轻人所喜爱。
Rome was not built in a day.
罗马城不是一天建成的。
2.被动语态的疑问句
把Be动词放在句首,就构成了被动语态的一般疑问句;而疑问词+一般疑问句就构成了被动语态的特殊疑问句了。
Is Chinese used only in China?
汉语只是在中国使用吗?
Were these computers made in the U.S.A.?
这些计算机是美国制造的吗?
Yes,they were.是的。
No,they weren't.不是。

初中英语被动语态的知识点详解
1.不及物动词没有被动语态
因为不及物动词没有宾语,所以若将其用于被动语态则没有主语,故不能用于被动语态。
但是值得注意的是,有些英语中的不及物动词,译成汉语时却可能是及物的,很容易出错,这类动词如:take place(发生),happen(发生),come about(发生),break out(爆发),appear(出现),disappear(消失),last(持续),arise(出现,发生)等:
A fire broke out during the night.夜间发生了火灾。
Influenza usually breaks out in winter.流感通常发生在冬季。
Use this money when the need arises.有需要时就使用这笔钱。
2.某些静态动词不用于被动语态
英语有些静态动词(如have, lack, fit, hold, suit, resemble等)通常不用于被动语态,如以下各句均不能变为被动语态:
My shoes dont fit me.我的鞋不合适。
The young man lacks experience.这个年轻人缺乏经验。
The hall holds 1000 people.大厅可容纳1000人。
3.宾语为相互代词和反身代词时不用于被动语态
由于相互代词和反身代词通常不能用作主语,所以当它们用作动词宾语时,句子不能转换成被动语态:
We should help each other.我们应该互相帮助。
英语被动语态知识
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 sth.”。
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?
英语中有多少种被动语态形式
英语中有十种被动语态:
1、一般现在时:主语 + am/is/are + 过去分词
2、一般过去时:主语 + was/were + 过去分词
3、一般将来时:主语 + shall/will + be + 过去分词
4、过去将来时:主语 + should/would + be + 过去分词
5、现在进行时:主语 + am/is/are + being + 过去分词
6、过去进行时:主语 + was/were + being + 过去分词
7、现在完成时:主语 + have/has + been 过去分词
8、过去完成时:主语 + had been + 过去分词
9、将来完成时:主语 + shall/will + have been + 过去分词
10、过去将来完成时:主语 + should/would + have been + 过去分词
被动语态简介:
被动语态是动词的一种形式,用以说明主语与谓语动词之间的关系。英语的语态共有两种: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。被动语态是动词的一种特殊形式,一般来说,只有需要动作对象的及物动词才有被动语态。
以上内容参考 百度百科-被动语态
初中英语被动语态结构和例句
1:英语语态有主动语态和被动语态两种。主动是动作的执行者,叫做主动语态;主语是动作的承受者,叫做被动语态。
Many people use computers. 许多人使用电脑。
Computers are used by many people. 电脑被许多人使用。
2:被动语态的基本结构是“be+及物动词的过去分词”(be + done)。Be有人称,数和时态的变化。一般现在时的被动语态结构:主语+am/is/are+及物动词的过去分词。
3:一般现在时的被动语态的句式变化:
(1)肯定句:主语+am/is/are+及物动词的过去分词。
如:Cars are made by them. 汽车是由他们制造的。
(2)否定句:主语+am/is/are+not+及物动词的过去分词。
如:Cars are not made by them. 汽车不是由他们制造的。
(3)一般疑问句:Am/Is/Are+not+主语+及物动词的过去分词?
如:Are cars made by them? 汽车是由他们制造的吗?
4:主动语态变成被动语态的三步曲:
(1)将主动结构的宾语变成被动结构的主语(宾语若为人称代词,宾格变成主格)。
(2)将主动结构的谓语动词变成“be+及物动词的过去分词”形式(注意人称,时态和数的变化)。
(3)在动词的过去分词之后加介词by,再将主动结构中的主语放在by之后(若为人称代词,主格变成宾格)。
