初二英语被动语态
中考英语被动语态精讲练
被动语态：表示主语是动作的承受者例1：English is spoken by many people. (主语English是动词speak的承受者。
)例2：This English song is sung by Millie. (主语this English song是动词sing发出的，即sing这个动作的承受者。
)(二) 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。
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。
The window was broken by mike. 窗户是迈克打破的。
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。
The window was blown by wind.窗户被风吹开了。

It is believed that he is a spy. 大家相信他是个间谍。
(三) 被动语态的构成被动语态由“be＋及物动词的过去分词”构成。
注：不及物动词本身没有被动语态。
人称、数和时态的变化是通过be的变化表现出来的。
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。
(四) 主动句变成被动句主动变被动的基本“三部曲”1.变宾为主：即变主动语态的动词宾语为被动语态的主语，当宾语为人称代词的时候，注意宾格和主格的转换。

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。
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（p.p.）"构成。
人称、数和时态的变化是通过be的变化表现出来的。
被动语态在各种时态中的构成。
一般现在时:am/is/are+ p.p.一般过去时:was/were+ p.p一般将来时:will/shall be+ p.p现在进行时:am/is/are being+ p.p过去进行时:was/were being+ p.p现在完成时:have/has been+ p.p过去完成时:had been + p.p情态动词的被动语态,由情态动词+be+p.p"构成不定式的被动语态：to be + p.pThere are twenty more trees to be planted.特殊情况:1.主： The teacher asked li Ping to clean the floor.（ask sb.to do sth.）被：Li Ping was asked to clean the floor2.主：He made the boy work for two hours yesterday. （make sb.

(完整)初中英语被动语态讲解
初中英语被动语态解说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履行者，被动语态表示主语是动作的蒙受者。
一、被动语态的组成英语动词的被动语态由助动词be+及物动词的过去分词组成。
助动词be一定与主语的人称和数目保持一致，态的变化。
比如：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）动作的履行者不知道是谁或难以说明经常用被动语态。
比如：并有时Street lights are often turned on at six in winter.The new test book will be used next term.（ 2）当动作的蒙受者比起动作的履行者来说更能惹起人们的关怀而需要加以重申时，要用被动语态。
比如：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许直接宾语都可变为被动语态中的一个主语，另一个保存不变。
变为主语的假如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。
比如： 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。

初二英语被动语态专练一、被动语态概述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。

（主动语态）The door was opened.这扇门被打开了。
（被动语态）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。
被动语态的时态变化只改变be的形式，过去分词部分不变。
疑问式和否定式的变化也如此。
1、初二被动语态的时态较常见的六种，现以动词clean为例列表说明：2、被动语态的句式变化：以一般现在时和动词invite为例，列表说明被动语态的句式变化：3、含有情态动词的被动语态情态动词的被动语态结构为：情态动词+be+过去分词；其时态及句型的变化仅由情态动词完成，“be+过去分词”部分不变。
如：Tables can be made of stone.桌子可由石头制造。
Tables could be made of stone at that time.那时桌子可由石头制造。
（一般过去时）Can tables be made of stone? 桌子能用石头制造吗？（疑问句）三、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。

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。
如：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。

例如：English is spokenby 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。

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。
初中英语被动语态(人教版)
三、被动语态(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 te acher.(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。

初二英语被动语态
初二英语被动语态专练一、被动语态概述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。
汉语往往用“被”、“受”、“给”等词来表示被动意义。
如：He opened the door.他打开了这扇门。
（主动语态）The door was opened.这扇门被打开了。
（被动语态）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。
被动语态的时态变化只改变be的形式，过去分词部分不变。
疑问式和否定式的变化也如此。
1、初二被动语态的时态较常见的六种，现以动词clean为例列表说明：2、被动语态的句式变化：以一般现在时和动词invite为例，列表说明被动语态的句式变化：3、含有情态动词的被动语态情态动词的被动语态结构为：情态动词+be+过去分词；其时态及句型的变化仅由情态动词完成，“be+过去分词”部分不变。

Tables could be made of stone at that time.那时桌子可由石头制造。
（一般过去时）Can tables be made of stone? 桌子能用石头制造吗？（疑问句）三、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。
如：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。
如：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。
初二被动语态
被动语态讲解一、各种时态的被动语态一般现在时：am／is／are＋动词过去分词Cars are made by them。
一般过去时：was／were＋动词过去分词The MP3 was bought by my father。
一般将来时：will/shall/be going to be＋动词过去分词The bridge will be completed in ten days.现在完成时：have／has been＋动词过去分词The meeting has been put off。
二、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。
歌诀是：情态动词变动，情态加be加“过分”.例如:we can repair this watch in two days. →This watch can be repaired in two days.We must finish this work soon。
→This work must be done soon.We have to clean the classroom。
→ The classroom has to be cleaned by us。
三、主动语态变被动语态需要注意的几个问题.（1)时态保持一致.I have repaired my computer。
-—-My computer has been repaired.（2）如果要说出动作的执行者，并且这个执行者可以作主动语态中主语时，就用by短语，如果后面的词表示地点，不是动作的执行者,就用in短语.It is made by us. It is made in Wuhan。
(3）主动句的主语是代词的主格形式，变成被动句by的宾语时要用其宾格形式.He cleaned the car. → The car was cleaned by him.(4）疑问句的被动语态，用be动词的对应形式代替doDoes she drive this car? →Is this car driven by her?（5）谓语为动词短语的被动语态不能丢掉动词短语的介词或副词。
初二被动语态语法知识点
【被动语态】（一）语态：英语的语态是通过动词形式的变化表现出来的。
英语中有两种语态：主动语态表示主语是动作的执行者。
例如：Many people speak Chinese 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：Chinese is spoken by many people. 主语English是动词speak的承受者。
（二）被动语态的构成）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.He cut down a tree. → A tree was cut down by him.(七)语态转换时所注意的问题1. 主动语态变被动语态，谓语动词的时态要与原句时态一致，谓语动词的数与新主语保持一致。
We have bought a new computer.A new computer has been bought. A new computer have been bought. (错误)2. 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。

Tables could be made of stone at that time.那时桌子可由石头制造。
（一般过去时）Can tables be made of stone? 桌子能用石头制造吗？（疑问句）三、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。
如：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。
如：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。
如：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：It is reported that…据报道It is said that…据说It is believed that…大家相信It is suggested that…有人建议四、主动语态变为被动语态转换图示：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：Tom killed him. → He was killed by Tom.(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by…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。
如：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，变为被动句时，通常删去“by…”，但原主语被强调时除外。
如：They set up this hospital in 1975.→This hospital was set up in 1975. 这所医院建于1975年。
Only he can finish the job. → 只有他能完成这项工作。
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。
如：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.五、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，have如：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。
