被动语态知识点讲解(更全面,思路清晰)
被动语态知识点讲解(更全面,思路清晰)被动语态知识点讲解被动语态是英语语法中的重要概念之一,它在句子中常常用来强调动作的接受者或者对象。
在本文中,我们将详细介绍被动语态的用法和结构,并提供一些实例用以帮助读者更好地理解和运用被动语态。
一、什么是被动语态被动语态是指句子的主语是动作的接受者或对象,而动作的执行者成为句子的宾语或介词短语。
被动语态使用助动词“be”加上动词的过去分词形式构成。
二、被动语态的结构根据被动语态的不同时态,其结构会有些许变化。
下面我们将一一介绍几种常见时态的被动语态结构:1. 一般现在时态:被动语态的一般现在时结构为:[be(am/is/are)] + [过去分词] + [by + 主语执行者]示例:1) 主动句:She writes a book.被动句:A book is written by her.2) 主动句:They make delicious cakes.被动句:Delicious cakes are made by them.2. 现在进行时态:被动语态的现在进行时结构为:[be(am/is/are)] + [being] + [过去分词] + [by + 主语执行者]示例:1) 主动句:He is washing the car.被动句:The car is being washed by him.2) 主动句:They are building a house.被动句:A house is being built by them.3. 一般过去时态:被动语态的一般过去时结构为:[be(was/were)] + [过去分词] + [by + 主语执行者]示例:1) 主动句:She bought a new car.被动句:A new car was bought by her.2) 主动句:They painted the wall.被动句:The wall was painted by them.4. 过去进行时态:被动语态的过去进行时结构为:[be(was/were)] + [being] + [过去分词] + [by + 主语执行者]示例:1) 主动句:He was cleaning the house.被动句:The house was being cleaned by him.2) 主动句:They were repairing the car.被动句:The car was being repaired by them.三、被动语态的用法被动语态的使用可以有多种情况,下面是几个常见的用法:1. 强调行为的接受者:被动语态可以强调动作的接受者或者对象,使其在句子中得到突出。
被动语态讲解
初中被动语态英语动词有主动语态和被动语态之分。
主动语态句子中的主语是动作的执行者,被动语态句子中的主语是动作的承受者。
被动语态由“be + v-ed”构成。
关于动词的语态变化请看下表:动词的语态变化一.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。
3.变成的被动语态的主语与谓语在单复数上保持一致。
二、被动语态用于以下几种情况1. 不知道或没有必要指出动作的执行者。
如:Many new buildings are built in our city.2. 强调动作的承受者。
如:The wounded man has been sent to a hospital.3. 动作执行者有比较长的修饰语。
如:The person was supported by those who wished to have a ch ance to make friends with him.4. 出于礼貌,不愿说出动作的执行者。
如:You are requested to attend the party三,被动语态的基本用法:1使用被动语态时应注意的几个问题。
1). 带双宾语的主动结构的句子,变为被动语态结构时,只能将其中的一个宾语变为主语,另一个宾语仍要保留。
如果保留的是间接宾语,要在间接宾语之前加上介词to或for.如:We are taught English by her.或English is taught to us by he r.2). 主动语态中的不带to的动词不定式作宾补变为被动语态时,要加上不定式符号to.如:The boss made him work over twelve hours a day.He was made to work over twelve hours a day.3). 短语动词用于被动语态应作为一个整体,不能丢掉其中的介词或副词。

(完整)被动语态讲解
被动语态讲解一、总述:英语动词有两种语态,即主动语态(The Active Voice)和被动语态(The Passive Voice)。
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。
They will build a new bridge over the river. (主动)A new bridge will be built over the river. (被动)汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be + 及物动词的过去分词构成。
二、被动语态的形式1) 常用时态的被动语态的构成:被动语态的基本形式为助动词be + 及物动词的过去分词,即be done。
被动语态的时态、人称和数的变化主要体现在be的变化上,其形式与系动词be的变化形式完全一样.以give 为例,列表如下:一般现在时:am / is / are + given一般过去时:was / were +given一般将来时:shall / will +be+ given过去进行时:was / were + being + given现在进行时:am / is / are + being + given过去完成时:had + been + given现在完成时:have / has + been + given将来完成时:shall / will + have been + given过去将来时: should / would +be+ given现在完成进行时:have/has been being done含情态动词的被动语态:情态动词+be done[注]被动语态没有将来进行时和过去将来进行时.2)被动语态的否定式:在第一个助动词后加not构成.Russian is not taught in our school. 我们学校不教俄语。
3)被动语态的疑问式:把第一个助动词提到主语之前,句尾加问号构成。
被动语态讲解
被动语态一、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.特殊疑问句(疑问词+一般疑问句)How often is your classroom cleaned?What are knives used for?2.When was the new shop built last year?B. Our bikes were stolen outside the movie theater.Where were your bikes stolen?3.A. A new hospital will be built in our city.Will a new hospital be built in our city?What will be built in our city?B.

被动语态的用法讲解
被动语态的用法讲解一、什么是被动语态被动语态是英语中一种常用的句式结构,它强调主语受到动作的影响或承受了某种行为。
在被动语态中,主动词的对象变成了句子的主语,而原来的主语则变成了介词by短语中使用。
被动语态特别适用于当我们不知道或者不关心谁执行了动作时。
二、构造被动语态被动语态由“be”(根据时态和人称变化)+过去分词构成。
下面是各种时态下的例子:1. 一般现在时:am/is/are + 过去分词主动:She eats an apple.被动:An apple is eaten by her.2. 一般过去时:was/were + 过去分词主动:They opened the door.被动:The door was opened by them.3. 一般将来时:will be + 过去分词主动:He will write a book.被动:A book will be written by him.4. 现在完成时:has/have been + 过去分词主动:We have finished the project.被动:The project has been finished by us.5. 现在进行时:am/is/are being + 过去分词主动:She is reading a book.被动:A book is being read by her.6. 过去进行时:was/were being + 过去分词主动:They were painting the house.被动:The house was being painted by them.三、被动语态的用法1. 强调行为受害者被动语态用于突出行为或事件的受害者,使其成为句子的重点。
例如:主动:The dog bit John.被动:John was bitten by the dog.在这个例子中,主语从"dog"变成了"John",强调了John受到了咬伤。
被动语态讲解及注意事项
被动语态讲解及注意事项被动语态是英语中一种常用的句型结构,它用于强调动作的承受者或接受者,而不是动作的执行者。
当主语是动作的执行者时,使用主动语态;当主语是动作的承受者或接受者时,使用被动语态。
被动语态的构成:被动语态的构成是由“助动词be + 及物动词的过去分词形式(be + past participle)”组成。
be动词根据句子的时态和人称来变换。
被动语态的示例:主动语态:He eats an apple.被动语态:An apple is eaten by him.主动语态:They will build the house.被动语态:The house will be built by them.主动语态:She has written a book.被动语态:A book has been written by her.被动语态的注意事项:1.当主动语态的句子中有宾语时,宾语变成被动语态的主语,而主语则成为被动语态中的介词短语。
例如:主动语态:She is eating an apple.被动语态:An apple is being eaten by her.注意:主动语态中的宾语“an apple”变成了被动语态中的主语,“she”则成为了被动语态中的介词短语“by her”。
2. 当主动语态的句子中没有宾语时,用“by + 主语”来表示动作的执行者。
例如:主动语态:He sings well.被动语态:Well is sung by him.注意:原句中没有宾语,所以被动语态中使用“by + 主语”来表示动作的执行者。
3.若主动语态中的动词是不及物动词,则不能使用被动语态。
例如:主动语态:He sleeps.被动语态:错误,不能用被动语态。
4. 根据句子的时态,使用相应的be动词形式。
下面是be动词在不同时态和人称下的变化:一般现在时:am/is/are一般过去时:was/were一般将来时:will be现在进行时:am/is/are being过去进行时:was/were being现在完成时:has/have been过去完成时:had been5.注意主动语态中的时态、人称和数量与被动语态中的时态、人称和数量的一致性。
英语语法被动语态讲解
被动语态一、被动语态在各种时态中的结构一般现在时:be done(be随人称变化)一般过去时:was/were done一般将来时:will be done现在进行时:be being done(前面的be随人称变化,后面的being固定)过去进行时:was/were being done(being固定)现在完成时:have/has been done过去完成时:had been done过去将来时:would be done将来完成时:will have been done将来进行时:will be being done(being固定)将来完成进行时:will have been being done现在完成进行时:have been being done过去将来完成时:would have been done过去完成进行时:had been being done过去将来进行时:would be being done过去将来完成进行时:would have been being done二、被动语态的基本用法:被动语态表示一种主语和谓语之间的关系,当主语是动作的承受者时,就需要用到被动语态,汉语中所说的,“汽车被撞坏了”“钢笔被修好了” 等句子就是一种被动语态的句子,在汉语中常用“被”“由”等词来表示这种被动语态。
在英语中则用动词的被动语态形式来表示。
被动语态中还可用by 短语加在句后表示被动语态中动作的发出者。
也就是谓语动词动作的逻辑上的主语,被动语态常用在下列情况。
1、不知道谁是谓语动词动作的执行者时,或者没有必要说出谁是执行者时。
The glass was broken last night. 玻璃昨天被打破了。
His bike has been stolen. 他的自行车被偷了。
He was asked to go there once more. 他被要求再去那儿一次。
2、为了强调或突出动作的承受者时。
被动语态讲解
被动语态讲解语态:是动词的一种形式,用来表明主语与谓语动词之间的关系。
主动语态:表示主语是(谓语)动作的执行者。
谓语动词为主动语态的句子叫主动句。
被动语态:表示主语是(谓语)动作的承受者。
谓语动词为被动语态的句子叫被动句。
被动语态是动词的一种特殊形式,一般说来,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).He cleans the room every day .The room is cleaned by him every day ..Tom mended the car just now .The car was mended by Tom just now .一、被动语态的谓语构成形式:“be + 过去分词”1. 被动语态的基本时态变化:. be随时态的变化而变化,被动语态谓语部分的第一个助动词为主要助动词可用来帮助构成否定句和疑问句。
1) 一般现在时:am/is/are +done (过去分词) (am/is/are为助动词)例The room is cleaned every day . (肯定,否定,一般疑问,特殊疑问,反意疑问)--- The room is not cleaned every day .---Is the room cleaned every day ? No, it isn’t . Yes , it is .---How often is the room cleaned ?---The room is cleaned every day , isn’t it ?---The room is not cleaned every day , is it ?(I am given a gift on my birthday each year .The rooms are painted every two years .This song is often sung by children .孩子们常唱这首歌。

例如:主动语态:The cat chased the mouse.(猫追逐老鼠。
)被动语态:The mouse was chased by the cat.(老鼠被猫追逐。
)被动语态的结构被动语态的结构是由不同的“助动词”(auxiliary verbs)构成的,并且根据所使用的时态和语气而变化。
以下是不同时态和语气下的被动语态结构:•现在时被动语态:am/is/are + 过去分词–例如:The ball is being thrown.(球正在被扔。
)•过去时被动语态:was/were + 过去分词–例如:The ball was thrown by him.(那个人扔了球。
)•现在完成时被动语态:have/has been + 过去分词–例如:The cake has been eaten.(蛋糕已经被吃了。

01 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。
02 不同时态的被动语态通过在be动词后面添加不同 的时态助动词(如do/does/did)和情态动词 (如can/could/may/might)来构成。
02 被动语态的否定形式是在be动词后面加not,例 如“The book is not written by him.”
VS
当动作的承受者是特定的人或组织时, 为了表示尊重或突出其重要性,也可 以使用被动语态。例如,“The president was greeted by the crowd.”(总统受到了人群的欢迎。) 这句话中,我们强调的是总统受到了 欢迎,而不是强调是谁在欢迎总统。
保持句子平衡,避免句式单调

被动语态
语态(voice)是个语法范畴,它是一种动词形式, 表示动词的主语与该动词所表示的动作之间的 主动和被动关系。当主语是动作的执行者时, 动词用主动语态(Active Voice);如果主语 是动作的承受者,动词便用被动语态(Passive Voice)。
We cleaned the classroom yesterday. 昨天我们打扫了教室。
口诀1:宾提前变主,主变介by宾,被动be加done,
时态看主动。
口诀2:如 遇双宾语,最好变间宾,如若变直宾,
间宾前加to / for (pass, lend, buy, write, bring, show, tell…)
பைடு நூலகம். He made me do the work. I was made to do the work by him.

动词的被动语态由“助动词be+及物动 词的过去分词”构成。当主动句变为被 动句时,原来的宾语变成了主语,原来 的主语变成了介词by 的宾语。主动句与 被动句的结构虽然不同,但动作的执行 者和承受者的关系并没有改变。
口诀3:这些动词真奇怪,主动句中to 离开,被动 句中to回来.(feel, listen to, hear, let have, make, look at, see, watch…)
4.They take good care of the baby.
The baby is taken good care of by them.
Mr. Smith was given a book yesterday (by me).
3. 含有介词动词的主动句的转换 They have never listened to him. 人家从不听他的话。 He has never been listened to.
表示被动意义的主动句: Cotton feels soft. 棉花摸上去很柔软。 Ripe apples pick easily. 熟了的苹果容易摘下来。
注意:含动词词组的被动语态,须将其看作一个 整体,不可把它们分隔开来。
有些情况下动词的主动形式也可以表示被动意义。
一、表示“开始”;“结束”类的动词。常见 的这类动词有begin, start, open, close, end, finish, stop等。例如:
School begins in September. The stores in this area open later at weekends than at weekdays.
当主动句的宾语是that引导的宾语从句, 可转换为两种形式的被动句。
1) 用先行的it作形式主语,把宾语从句变成后置的 主语从句; 2) 把宾语从句里的主语变成被动句的主语,同时把宾 语从句中的谓语变成不定式短语。
People believe that he is an honest boy. 大家认为他是个诚实的孩子。
作将于三小时后完成。 The baby must be looked after well. 这孩子必须被好好照顾。
在被动句中有时用by- 词组,有时不用。一般 来说,当动作的执行者为谁不甚清楚,不甚重要 或难以说出时,通常不用by。但有时为了强调 动作执行者或者由于上下和结构上的需要则必须 使用 by 词组。例如:
