被动语态的用法(有例句)
一、被动语态的用法：
1、不知道或没有必要指出谁是动作的执行者时。
The bridge was built last year.这座桥是去年建造的。
He was elected chairman.他被选为主席。
2、当更加强调动作的承受者时。此时动作的执行者由by引导置于谓语动词之后，不需要时可以省略。
The room hasn't been cleaned yet.房间还没有打扫。
The tiger was killed by him.老虎被他杀死了。
3、当动作的执行者不是人时，多用被动语态。如：
The window was blown by wind.窗户被风吹开了。
The whole village has been washed away by the flood.整个村庄都被洪水冲走了。
4、表示客观的说明常用"It is + 过去分词."句型。
It is said that Lucy has gone abroad.据说露茜已经出国了。
It is believed that he is a spy. (=He is believed to be a spy.)大家相信他是个间谍。
其它常见的"It is + 过去分词+ that"句型还有
据报道
It is reported that…
据说
It is said that…
大家相信
It is believed that…
有人建议
It is suggested that…
二、主动语态变为被动语态
1、主动语态变为被动语态的步骤：
（1）将主动句的宾语变为主语：
注意：如果主动句的宾语是代词，需将其由宾格变为主格。如：
by Tom.
Tom killed him. → He was killed
（2）将动词改为"be+过去分词"。
注意：
They held a meeting yesterday. → A meeting was held by them yesterday. 他们昨天开会了。
（3）将主动语态的主语改为be…放在谓语动词后。
注意：如果原主语是代词，则应由主格变为宾格。
He sang a song. → A song was sung by him.
2、主动语态变为被动语态的注意事项：
（1）主动句中的主语如果是people, we, you, they, somebody等含糊地表示"人们"、"大家"的单词，变为主动句时，通常删去"by…＂，但原主语被强调者除外。如：
They set up this hospital in 1975. → This hospital was set up in 1975. 这所医院建于1975年。
只有他能完成这项工作。
Only he can finish the job. →
The job can be finished only by him.这项工作只能由他来完成。
（2）含有双宾语，即直接宾语和间接宾语的句子，每个宾语都可变为被动语态
的主语，即其被动语态有两种形式。但多以间接宾语作主语。
Jack told us the truth.杰克告诉了我们真相。
We were told the truth by Jack.
The truth was told (to) us by Jack.
三、动词的主动形式表示被动之意
以主动形式表示被动之意的动词多为连系动词，如：look, feel, smell等。下列动词没有被动式：happen，cost，take，have
An accident was happened yesterday.（×）昨天发生了一起事故。
An accident happened yesterday.（）
The flower smells sweet.这花闻起来很香。
The watch looks good.这表看起来很好。
This book sells well.这本书畅销。

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

初中英语被动语态讲解
英语被动语态讲解 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。 一、被动语态的构成 英语动词的被动语态由助动词be+及物动词的过去分词构成。助动词be必须与主语的人称和数量保持一致，并有时态的变化。例如：The man was fooled by the two boys. The book has been translated into several languages. 二、被动语态的用法 （1）动作的执行者不知道是谁或难以说明时常用被动语态。例如： Street lights are often turned on at six in winter. The new test book will be used next term. （2）当动作的承受者比起动作的执行者来说更能引起人们的关心而需要加以强调时，要用被动语态。例如： This kind of bicycle is not sold in our shop. The thief was caught by a policeman yesterday. （3）含有双宾语的句子，主动句中的间接宾语或者直接宾语都可变为被动语态中的一个主语，另一个保留不变。变为主语的若是主动句中的直接宾语在变为间接宾语前则需加介词to 或for。 例如：The pianist gave the pupils(间接宾语)some advice(直接宾语) →The pupils were given some advice by the pianist.→Some advice was given to the pupils by the pianist. (4)在主动语态句中动词make、have、let、see、watch、hear、feel等后接动词不定式作宾语补足语，动词不定式不加to。但变成被动语态时后面的不定式都须加上to。 例如：The boss made them work ten hours a day. →They were made to work ten hours a day. A boy saw him enter the house. →He was seen to enter the house. 三、被动语态的时态 教材中出现了四种时态的被动语态及带有情态动词的被动语态。 一般现在时构成：助动词be + 动词的过去分词例如：This kind of car is made in shanghai. 一般过去时构成：助动词was/were + 动词的过去分词例如：The bridge was built in 1992. 现在进行时构成：be + being + 动词的过去分词例如：A new bridge is being built in my hometown. 一般将来时构成：will/be going to do + be + 动词的过去分词例如：These books are going to be posted tomorrow. 带有情态动词的被动语态构成：情态动词+ be + 动词的过去分词例如：Can this walkman be repaired here? ※主动语态改为被动语态的步骤： ①主动语态中的宾语变为被动语态句中的主语； ②主动语态句中的动词改为相应的被动语态； ③主动语态句中的主语变为被动语态句中by的宾语。 主动语态句中的谓语动词带有双宾语，即直接宾语和间接宾语时，转换方法有两种： ①把间接宾语转化为主语，保留直接宾语 ②把直接宾语转化为主语，保留间接宾语。此时，一般需在间接宾语前加适当的介词（通常是介词for或to)。 在短语see sb. do sth. 中，动词see后跟不带to的不定式作宾补。改为被动语态时要加上to。用于这一结构的谓语动词一般是表示知觉的动词如see, hear,watch,find等，以及使役动词make, let等。
