英语被动语态怎么表示
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。汉语往往用"被""受""给"等被动词来表示被动意义 。
具体构成:
1、一般现在时的被动语态构成:is / am / are + 及物动词的过去分词
Our classroom is cleaned everyday. 我们教室每天都被打扫。
2、一般过去时的被动语态构成:was / were + 及物动词的过去分词
A new shop was built last year. 去年修了一座新商店。
实义动词
实义动词的一般过去时态
肯定句要使用动词的过去式,否定句和疑问句要使用助动词do和does 的过去式did.
否定句:主语+didn't +动词原形+宾语
疑问句:Did +主语+动词原形+宾语
以上内容参考:百度百科-一般过去时
英语中的句型是什么
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.例如:English is spoken by many people.主语English是动词speak的承受者. 所谓主动句就是由主动态动词(词组)作谓语动词的句子,而被动句则是由被动态动词(词组)作谓语动词的句子. 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“助动词be+及物动词的过去分词”构成.人称、数和时态的变化是通过be的变化表现出来的.现以teach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+taught
一般过去时:was/were+taught
一般将来时:will/shall(be going to) be+taught
现在进行时:am/is/are being+taught
过去进行时:was/were being+taught
现在完成时:have/has been+taught
过去完成时:had been +taught
过去将来时:would(was/were going to) be+taught
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 more interesting novels were stolen last year. 一些新小说去年被写了.(没说小说是谁写的) This book was published in 1981.这本书出版于1981年.
(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 him.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.
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.
五、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.
例如: We can repair this watch in two days. This watch can be repaired in two days. You ought to take it away. It ought to be taken away. They should do it at once. It should be done at once.

被动语态的结构为“助动词be+及物动词的过去分词(p.p)”。被动语态的不同时态是通过be的时态变化来表示的,其人称和数方面应与主语保持一致。

其具体变化为:
一般现在时:am/is/are+p.p.
一般过去时:was/were+p.p.
一般将来时:shall /will be +p.p.
现在完成时:have /has been +p.p.
现在进行时:am/is/are+being+p.p.
过去将来时:should /would be +p.p.
含情态动词的被动结构:情态动词+be+p.p.例如:
① Chinese ______ by the largest number of people.(选D。考查一般现在时的被动语态)
A.speak B.is speaking C.speaks D.is spoken
② The boy ______ to get supper ready after school.(选C。考查一般过去时的被动语态)
A.were told B.is telling C.was told D.tells
③ A lot of new roads ______ built in the west of China.(选B。考查含情态动词的被动语态)
A.must B.must be C.has D.have
B.明确用法
被动语态常用于以下两种情况:
1.不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者;
2.强调动作的承受者。例如:
这棵树是那个男孩弄断的。
The tree ______ ______ by that boy. (填was broken)
C.熟练转换
1.将主动语态变被动语态的基本方法为:
①将主动语态的宾语作被动语态的主语;
②谓语动词变为“be+及物动词的过去分词”,并通过be的变化来表达出不同的时态;
③主动语态的主语变为介词by的宾语,组成介词短语放在被动结构中的谓语动词之后。(有时by短语可以省略)。
2.被动语态的一般疑问句是将一个助动词置于主语之前;否定句是在第一个助动词后加not;特殊疑问句的.语序为:疑问词+一般疑问句。例如:
① You must throw the broken pottery away at once.
The broken pottery ______ ______ ______ ______ at once.(同义句) (填must be thrown away)
② Where did they grow vegetables?(改为被动语态)
Where ______ vegetables ______ ?(填were;grown)
D.注意特例
将主动语态变被动语态应注意几个特殊情况:
1.含双宾语的主动结构变为被动结构时,有两种方法:
①将间接宾语变为主语,直接宾语保持不变;
②将直接宾语变为主语,间接宾语用介词to或for引导。例如:
① He told us a story.(变被动语态)
→We were told a story(by him).或:A story was told to us by him.
② Her mother gave her a new pen.(变被动语态)(填was given to)
A new pen ______ ______ ______ her by her mother.
2.短语动词的被动语态:在变为被动语态时,要将短语动词视为一个整体,其后的介词或副词不能省去。例如:
① This dictionary mustn't ______ from the library.[D]
A.take away B.taken awayC.are taken away D.be taken away
② She will take good care of the children.(变被动语态)(填be taken good care of)
The children will ______ ______ ______ ______ ______ (by her).
3.含有复合宾语的主动结构变被动结构时,通常将宾语变为被动句的主语,而宾语补足语就成为主语补足语。注意:省略to的不定式作宾补时,不定式符号to必须补上。例如:
Someone saw him swim in Qianling Lake yesterday.(变被动语态)
He ______ ______ ______ swim in Qianling Lake yesterday.
(填was seen to)
4.不定式的被动结构:动词不定式的被动语态为“to be +过去分词”。例如:
The radio says a wild animal zoo is to ______ in our city.
A.be building B.build C.be built D.built [C]
5.以疑问代词开头的疑问句转换成被动句时要注意词序:应将主动句中的疑问代词改为介词by的宾语,但仍然放在句子开头。例如:
Who has broken the cup?(改为被动语态)
→By whom has the cup been broken?
E.注意区别
被动语态和过去分词作表语的区别:
1)含义不同:被动语态强调动作,重点说明动作由谁完成、怎样完成;而过去分词作表语通常用来描写情景,叙述人或事物的特征及所处的状态。试比较:
The window is broken.窗子破了。(系表结构)
The window is broken by him.窗子被他打破了。(被动语态)
2)用法不同:过去分词作表语时可以被 so,very,too等程度副词修饰,而被动语态则不能用so,very,too修饰,而需用much,very much,so much,too much修饰。试比较:
He was very interested in science.他对科学有极大兴趣。(系表结构)
I was so much surprised at the scene that I didn't know what to do.我被那种场面搞得大吃一惊,不知所措。(被动语态)
F.牢记(相关)句型
初中教材中与被动语态相关的句型有:
1.be covered with被……覆盖
2.be made of由……制作(发生物理变化) be made from由……制作(发生化学变化)
be made in由(某地)制造 be made by被(某人)制造
3.be used for被用来……
be used as被当作(作为)……来使用 be used to do sth.被用来做某事
4.It is said that...据说…… It is hoped that...希望……
It is well known that...众所周知……例如:
①—Your coat looks nice.Is it ______ cotton?[B]
—Yes.It's Shanghai.
A.made of;made by B.made of;made in
C.made for;made by D.made for;made in
② This machine is used ______ the room wet.[A]
A.for keeping B.as keeping C.keep D.to keeping
③ 据说在南京长江上又在建一座桥。
______ ______ ______ that ______ ______ is being ______ over the Changjiang River in Nanjing.
(填It is said;another bridge;built)
英文被动语态的例子
你好
英语的语态分为主动语态和被动语态两种,而在英语中习惯使用被动语态,汉语中以主动语态为主。中主动语态表示主语是动作的发出者或执行者,而被动语态则表示主语是动作的承受者。那么主动语态如何转化成被动语态呢?
一、被动语态的构成
被动语态由“be动词+过去分词”构成:如
Everybody likes the cute girl. 大家都喜欢这个可爱的女孩。(主动语态)
The cute girl is liked by everybody. 这个可爱的女孩受到大家的喜欢。(被动语态)
二、主动语态变被动语态的基本方法
将主动语态的宾语变为被动语态的主语,将主动谓语变为被动谓语(be+过去分词),将主动语态的主语变为by短语(在被动句中用作状语),如:
He finished the task. → The task was finished by him.
注:如果不强调动词发出者,被动语态中的by短语通常可以省略。
三、 特殊用法
主动句可以转换成两种被动句型,它们通常是一些表示客观说明的句子,如:
People believed that the old man is innocent. 大家相信那个老人是无辜的。
→ It’s believed that the old man is innocent.. 大家相信那个老人是无辜的。
→ The old man is believed to be innocent. 大家相信那个老人是无辜的。
比较上面两类被动句型可以发现,一类是“it+be+过去分词+that从句”,另一类则是“主语+be+过去分词+不定式”,通常可用于这两类被动句型的动词有suppose, think, understand, assume, believe, expect, presume, report, say, fear, feel, know,等,如:
It’s known that she is a kind girl. =She is known to be a kind girl. 大家知道她是个善良的女孩。
It’s expected that he will be better soon. = He is expected to be better soon. 他应该很快就会好起来。
以上就是主动句变被动句的方法。其实,主被动在我们写作或翻译过程中还是非常重要的,英语多被动,汉语多主动,所以学会这两种语态的转变对我们今后的学习至关重要。所以,希望大家能多思考对比,反复练习运用,尽快掌握该知识点。
