被动语态是英语语法中的一个重要部分，它可以用来表达某个动作的承受者，而不是执行者。
下面将介绍主动语态与被动语态的概念，以及被动语态的各种句型和主动语态改被动语态的方法。
一、主动语态与被动语态的概念主动语态是指主语执行动作，而被动语态是指主语承受动作。
需要注意的是，只有及物动词才有被动语态，而不及物动词必须带有介词才能有被动语态。
例如，“We listen to the teacher carefully in class”可以改写为“ The teacher is listened to by us carefully in class”，其中“the teacher”是被动语态的主语，而“us”是动作的执行者。
二、时态动词的被动形式例句被动语态可以用于各种时态，例如一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时和过去将来时等。
例如，“He is asked to do this”是一般现在时的被动语态，而“the story was told by her mother”是一般过去时的被动语态。
三、被动语态的各种句型被动语态有肯定句、否定句、一般疑问句和特殊疑问句等多种句型。
例如，“The song is liked by young people”是肯定句的被动语态，而“the song isn't liked by young people”是否定句的被动语态。
四、主动语态改被动语态的方法将主动语态改为被动语态的方法分为三步：将原句中的宾语改为主语，将动词改为变动形式be done（同时注意时态），将原来的主语（如果需要的话）放在介词by后面，以指明做事的人或物，如果没有必要则省去。
例如，“The man killed a tiger”可以改写为“a tiger was killed by the man”。
被动语态讲解及练习(附答案)
初中被动语态讲解及配套练习一、主动语态与被动语态的概念：英语动词的语态有两种：⑴主动语态：表示主语是动作的执行者⑵被动语态：表示主语是动作的承受者(常常没在有必要指出动作的执行者情况下使用) 例：They speak English. （主动语态）主谓宾English is spoken by them. （被动语态）主谓介词短语注：☆及物动词有被动语态，不及物动词必须带有介词才可以有被动语态。
例：⑴We listen to the teacher carefully in class.主谓宾→The teacher is listened to by us carefully in class.主谓介词短语⑵Ｗe laughed at him .→He was laughed at by us.二、被动语态的结构与用法：㈠结构：be +done (过去分词)被动语态中的be为助动词，无意义。
be可能是am , is , are也可能是was ,were或原形be。
注：☆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 后面的过去分词不变。
㈡用法：例：①Ｈistory is made by the people. (一般现在时)②Ｔhe cars were made in Tianjing in 1995. (一般过去时)③The tree will be cut down next year.(一般将来时)④Ｔhe room must be kept clean.（含有情态动词的被动语态）⑤The door is being opened.（现在进行时）⑥The film has been seen by me.（现在完成时）注：我们初中主要掌握前面四种的用法时态动词的被动形式例句一般现在时is done He is asked to do this.一般过去时was done The story was told by her mother.一般将来时will be done The problem will be discussed tomorrow. 现在进行时is being done The novel is being written.过去进行时was being done At that time the desk was being made.现在完成时has been done The house has been built.过去完成时had been done They said that their work had been finished. 过去将来时would be done He said the trees would be planted soon.三、被动语态的各种句型：１、Ｔhe song is liked by young people. (肯定句)２、Ｔhe song isn’t liked by young people（否定句）３、Is the song liked by young people ?（一般疑问句）４、Who is the song liked by ?=By whom is the song liked?（特殊疑问句）四、主动语态改被动语态的方法：方法分为三步：⑴把原句中的宾语改成主语⑵动词改为变动形式be done(同时注意时态)⑶原来的主语如果需要的话放在介词by后面，以指明做事的人或物，如果没有必要则省去例：The man killed a tiger.→A tiger was killed by the man .(改的过程中要注意时态和语态两个方面)五、特殊句型的被动语态：⑴含有使役动词（make /let /have）或感官动词（hear ,see, listen to ,look at ,find ,watch,feel 等）的句子，在主动语态中这些词后常跟不带to的动词不定式，但是在改成被动语态时，则一定要把省去的to再加上去，另外help这一个词在主动语态中后面的动词不定式可以带to,也可不带to, 但在被动语态中也必须把to加上去。
高中英语被动语态讲解与练习(含答案)
Grammar被动语态一、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2）has /have been done 现在完成时3）am/is /are being done 现在进行时4）was/were done 一般过去时5）had been done 过去完成时6）was/were being done 过去进行时7）shall/will be done 一般将来时8）should/would be done 过去将来时9）shall/will have been done 将来完成时（少用）10）should/would have been done 过去将来完成时（少用）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。
英语被动语态讲解及习题课件
英语被动语态讲解及习题课件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。
高中英语语法复习讲义+训练：被动语态(含答案)
高中英语语法复习讲义——被动语态一、语态概述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：主动语态和被动语态。
主动语态表示主语是动作的执行者。
巧记为：主动、主动、主去动。
被动语态表示主语是动作的承受者，即行为动作的对象。
巧记为：被动、被动、主被动。
例如：English is spoken by many people.主语English是动词speak的承受者。
主动态和被动态指的是动词形式，是词法概念;而主动句和被动句则指的是句子结构，从而是句法概念。
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+taught现在进行时：am/is/are being+taught过去进行时：have/has been+taught现在完成时：have/has been+taught记忆歌诀：被动语态be字变，过去分词跟后面。
注意：区分被动语态与“be+过去分词”结构be+过去分词”并不一定都是被动语态，有时是系表结构。
当“be+过去分词”表示动作时为被动语态，be是助动词，be后面的过去分词是主要动词，动作的对象是主语;当“be +过去分词”表示主语所处的状态时为系表结构，be是连系动词。
be后面的过去分词是表语，相当于形容词。
其区分办法如下：1 如果强调动作或句中有介词by引导出动作的执行者，该句一般为被动语态，否则为系表结构。
例如:The glass is broken.玻璃杯碎了。

(word版)初中英语被动语态深度讲解、练习及答案
初中英语被动语态深度讲解、练习及答案〔一〕语态的根本概念和种类语态是动词的一种形式，用来说明主语与谓语动词之间的关系。
所以英语的语态是通过动词形式的变化表现出来的。
语态有两种：主动语态和被动语态。
主语是动作的发出者为主动语态；主语是动作的接受者为被动语态。
如：Theybuiltthebridge.Thebridgewasbuiltbythem.(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／shallbe＋taught现在进行时：am／is／arebeing＋taught过去进行时：have／hasbeen＋taught现在完成时：have／hasbeen＋taught歌诀是：被动语态be字变，过去分词跟后面。
情态动词的被动语态是常考的一个知识点：情态动词+be+过去分词(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：Somenewcomputerswerestolenlastnight.一些新电脑在昨晚被盗了。
(不知道电脑是谁偷的)Thisbookwaspublishedin1981.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：thewindowwasbrokenbyMike.窗户是迈克打破的。
Thisbookwaswrittenbyhim.这本书是他写的。
Eighthoursperdayforsleepmustbeguaranteed.每天8小时睡眠必须得到保证。
歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到〔四〕主动语态变被动语态的方法与本卷须知歌诀是：宾变主，主变宾，by短语后面跟。

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 apresent 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.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.It is said that+ 从句及其他类似句型例 It is said that the boy has passed the national exam.(=The boy is said to have passed the national exam.)三、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 ， 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： h a p p e n , take place, comeout, come true, 等以主动形式表示被动意义。
例How do the newspapers come out?这些报纸是如何印出来的呢？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,look, 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四、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,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 repairin （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 lotof 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 yobave 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。
