初中英语被动语态讲解语态是动词的一种形式,表示句子中主语和谓语动词的关系,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。
只有及物动词才能用于被动语态。
一．被动语态的时态：1.一般现在时的被动语态：am /is/ are +动词的过去分词2.一般过去时的被动语态：was /were +动词的过去分词3.一般将来时的被动语态：will be +动词的过去分词4.现在进行时的被动语态：am /is /are +being +动词的过去分词5.现在完成时的被动语态：have /has +been +动词的过去分词6.情态动词的被动语态：情态动词+ be +动词的过去分词二．被动语态的基本用法:(1) 需要强调动作的承受者时The Great Wall is enjoyed by millions of people all over the worldEnglish is widely spoken in the world now.(2) 不知道或没必要指出动作的执行者时Mr. Wang is invited to the meeting today .The problem is dealt with now .(3) 当说话人需要强调客观时It is said that she was a beauty when she was young .三．主动主动语态变被动语态的变法：口诀：宾变主，主变宾，谓变be done ,时不变，数格必须随被变。
注：1.主动、被动的时态要一致。
2.主动、被动的句式要一致。

语态转换不被动语态的步骤1, 把原主动句中的宾语转换为被动语态的主语2, 把动词改为被动语态形式即"be+过去分词"。
3, 原来主动语态句子中的主语,如果需要就放在by的后面以它的宾格形式出现(因为by是介词,后面需跟宾格作介词的宾语。
初中英语被动语态讲解(精心整理)
被动语态专题◆定义语态是动词的一种形式，表示主语和谓语之间的关系。
主动语态和被动语态。
主动语态表示主语是谓语的执行者。
被动语态表示主语是谓语动作的承受者。
◆被动语态的构成：助动词be+及物动词的过去分词◆被动语态的时态：“主动语态变被动语态，时态不变动”，即助动词be 的时态要跟原主动语态中的时态保持一致。
请看下表：◆主动语态变被动语态的方法第一步：先确定主动句的主、谓、宾，找出其中的谓语动词。
第二步：把主动句中的宾语变为被动句的主语，若宾语是人称代词，变宾格为主格。
第三步：把主动句中的谓语动词变为“助动词be +及物动词的过去分词”，时态不变。
第四步：把主动句中的主语变为被动句中介词by的宾语(没必要说出动作的执行者时，“by+宾语”在句中常省略。
)，若主语是人称代词，应把主格变为宾格。
请对比下面的主动句和被动句：主动语态：They(主语)grow(谓语)tea(宾语)in the southeast of China.被动语态：Tea(主语)is grown(谓语)by them in the southeast of China.随堂演练（把下列句型改为被动句）1.Bruce writes a letter every week.→2.Li Lei mended the broken bike this morning.→3.We grow trees every spring.→4.My mother cleans our room every morning.→补充：①S + V +IO +DO双宾语的结构变为被动语态时，可把其中一个宾语变为被动语态的主语。
若将直接宾语变为主语，需根据习惯在原间宾语前加上介词to或for 。
用to的常见词有：give, show, send, lend, pass, pay, teach, throw, bring …….用for的常见词有：design, choose, sing, buy, get, cook ……随堂演练：（1）He gave me a book.→____________________________________(间接宾语作主语)→____________________________________ (直接宾语作主语)（2）My father bought me a new bike.→____________________________________(间接宾语作主语)→____________________________________ (直接宾语作主语)②S+ V+ O+ OC带复合宾语（宾语+宾语补足语）的结构变为被动语态时，只能将宾语变为被动语态的主语，宾语补足语不可变为主语。
初中中的被动语态用法详解
初中中的被动语态用法详解被动语态是英语中一个常用的语法结构，包含了及物动词的被动形式。
初中阶段，学生们需要逐渐掌握被动语态的用法。
本文将详细介绍初中中的被动语态用法。
一、被动语态的基本构成被动语态的基本构成由be动词的适当形式+过去分词构成。
be动词的形式根据句子的时态和主语的人称而定。
过去分词则根据动词的一般过去时的变化规则。
例如：- The car is repaired.（句子时态：一般现在时）- The car was repaired.（句子时态：一般过去时）- The car will be repaired.（句子时态：一般将来时）二、被动语态的用法1. 没有明确的执行者在被动语态中，我们强调动作的接受者而非执行者。
有时，在句子中并没有明确指出执行动作的人或事物。
例如：- The window was broken.（窗户被打破了。
）- The book will be published next month.（这本书将在下个月出版。
）2. 隐藏执行者在某些情况下，句子中刻意隐藏了动作的执行者。
例如：- The cake was eaten.（蛋糕被吃了。
）3. 顺序执行之动作被动语态常用于描述一系列按照一定顺序执行的动作。
例如：- The eggs are washed, peeled, and then boiled.（鸡蛋洗净、剥皮，然后煮熟。
）4. 惯用表达被动语态在某些固定的表达方式中也得到了广泛使用。
例如：- The decision was made.（决定已经做出。
）- The question was answered.（问题已经回答。
）三、主动语态与被动语态的转换在主动语态与被动语态之间进行转换时，需注意以下几点：1. 意义的改变：动作的焦点转移到了接受者身上，原主语成为了新的宾语；2. 动词形式的变化：be动词的形式和动词的过去分词形式相关；3. 语态的时态保持一致：主动语态的时态与被动语态的时态保持一致。
初中英语语法——被动语态
初中英语语法——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：[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 killedin 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 petdog 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：+ 状语+ 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。

初中英语被动语态讲解及练习一、什么是被动语态？被动语态是英语中的一种动词形式，用于表示句子的主语是动作的承受者而不是执行者。
在被动语态中，主语通常是动作的接受者，而动作的执行者则成为谓语动词的宾语。
二、被动语态的结构被动语态由助动词be（am, is, are, was, were）+及物动词的过去分词构成。
例如：原句：The boy kicked the ball.被动句：The ball was kicked by the boy.原句：They are eating the cake.被动句：The cake is being eaten by them.三、被动语态的用法1. 当我们不知道或不关心动作的执行者是谁时，常常使用被动语态。

）2. 当动作的执行者已经知道或不需要强调时，可以使用被动语态。
例如：English is spoken all over the world.（英语在世界各地都被使用。

）3. 当我们想要强调动作的接受者时，可以使用被动语态。
例如：The cake was eaten by Tom.（这块蛋糕是汤姆吃掉的。
）The book was read by all the students.（这本书被所有学生读过。
）四、被动语态的时态和语态转换1. 一般现在时的被动语态被动语态的一般现在时由am/is/are + 过去分词构成。
例如：原句：They build a house.（他们造了一座房子。
）被动句：A house is built by them.（一座房子被他们造了。
）2. 一般过去时的被动语态被动语态的一般过去时由was/were + 过去分词构成。

正如汉语中的被字句，英语中的“被字句”我们称之为被动语态。
英语中有两种语态：主动语态和被动语态。
英语的语态是通过动词形式的变化表现出来的。
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。
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。
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。
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。

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。
三．被动语态的句型肯定句：主语+be+动词过去分词否定句：主语+be+not+动词过去分词一般疑问句：Be+主语+动词过去分词特殊疑问句：特殊疑问词+be+主语+动词过去分词四．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.现在进行时：am／is／are being＋动词过去分词Is the bike being mended now?过去进行时：was／were being＋动词过去分词The dinned was being cooked.现在完成时：have／has been＋动词过去分词The meeting has been put off.过去完成时：had been＋动词过去分词Many old houses had been pulled down by the end of last year.过去将来时：would/should/be going to be＋动词过去分词Trees would be cut down.注：被动语态没有完成进行时，也没有将来进行时，如果有这类时态的主动结构，要变为被动结构，可用完成时态和一般时态。

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。

初中语法被动语态讲解
初中语法被动语态讲解被动语态定义: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 tostart.8) had been done 过去完成时例 By the end of last year, another new gymnasium had been completed inBeijing.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+(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 …),3. 被动语态的特殊形式1) 带情态动词的被动结构。
