高中英语知识点归纳被动语态的构成和用法总结高中英语知识点归纳:被动语态的构成和用法总结被动语态是英语语法中的一种语态形式,用来表示动作的承受者与执行者的关系。
在被动语态中,句子的主语是动作的承受者,而动作的执行者通常被省略或放在介词“by”后。
在本篇文章中,我们将对高中英语中被动语态的构成和用法进行归纳总结。
一、被动语态的构成被动语态的构成通常有以下几个要素:主语 + be动词 + 过去分词。
1. 主语(Subject):被动语态的主语是动作的承受者,通常是句子中的宾语。
2. be动词(Auxiliary verb):be动词根据句子的时态、人称和数进行变化,代表不同的情况,包括am/is/are(was/were)。
3. 过去分词(Past participle):过去分词是动词的一种非谓语形式,通常表示动作的完成或被动。
下面是一些例子,展示了被动语态在不同时态和人称中的构成形式:时态 | 构成形式-----------------一般现在时 | am/is/are + 过去分词一般过去时 | was/were + 过去分词一般将来时 | will be + 过去分词现在进行时 | am/is/are + being + 过去分词过去进行时 | was/were + being + 过去分词现在完成时 | have/has been + 过去分词过去完成时 | had been + 过去分词二、被动语态的用法被动语态在英语中有着广泛的应用。
以下是几种常见的使用情况:1. 强调动作的承受者:被动语态可以突出句子中动作的承受者,使其成为句子的主要焦点。
例如:- The house was destroyed by the earthquake.(房子被地震摧毁了。
) - The book was written by a famous author.(这本书是由一位著名作家写的。
)2. 描述客观事实:当注重描述客观事实时,被动语态可以更加准确地传达信息。
被动语态的用法归纳总结一、概念和基本结构被动语态是英语中的一种句子结构,表示主语是动作的承受者,而不是执行者。
通常由以下形式构成:be动词(am/is/are/was/were)+过去分词。
二、被动语态的用途1. 突出某个动作或事件的接收者,强调对象。
2. 强调对主语造成影响或结果的行为,而非行为本身。
3. 当无须提及或不知道执行者时使用。
4. 在科学研究和实验报告中经常使用被动语态。
三、被动语态的时态变化1. 一般现在时:am/is/are + 过去分词例:The car is washed every week.每周都会给这辆车清洗。
2. 现在进行时:am/is/are being + 过去分词例:The house is being painted by the workers.工人正在油漆这座房子。
3. 一般过去时:was/were + 过去分词例:The book was written by Mark Twain.这本书是马克·吐温写的。
4. 过去进行时:was/were being + 过去分词例:The crops were being harvested when the storm hit.暴风雨袭击时农作物正在收割。
5. 一般将来时:will be + 过去分词例:The package will be delivered tomorrow.这个包裹明天将被送到。
6. 现在完成时:has/have been + 过去分词例:The problem has been solved by our team.这个问题已经被我们的团队解决了。
四、主动语态和被动语态的转换1. 主动语态变被动语态把主动句的宾语移到前面作为被动句的主语,谓语动词改为相应形式的be动词,原主语成为介词by后的短语(可省略)。
例:Active: They built a new bridge last year.被动:A new bridge was built by them last year.2. 被动语态变主动语态将被动句的主语转化为主格作为主句的主语,谓语使用与原句中be表达时态、人称和数一致的动词原形。
高中英语知识点归纳被动语态被动语态是英语语法中的一个重要知识点。
在使用被动语态时,主语是承受者,而动作的执行者则成为谓语的一部分。
这一语法结构在表达特定情况和强调动作承受者时非常有用。
本文将对高中英语中常见的被动语态知识点进行归纳总结。
一、被动语态的构成被动语态由助动词“be”(is, am, are, was, were, been)和动词的过去分词构成。
动词的过去分词可根据动词的不同形态进行变化,常见的变化规则包括加“-ed”、改变拼写或使用不规则变化。
二、被动语态的用法1. 描述普遍情况或客观事实:Inventions are made every day.2. 强调动作承受者:The cake was eaten by the children.3. 避免指责或强调行为:Mistakes were made, and lessons were learned.4. 表示不明或未指定的主语:Money was stolen from the bank.三、被动语态的时态被动语态根据需要使用不同的时态。
下面是常见的被动语态时态使用示例:1. 现在时态:The car is washed by my brother every week.2. 过去时态:The letter was sent yesterday.3. 将来时态:The contract will be signed next week.4. 现在进行时态:The house is being built by a group of workers.5. 现在完成时态:The book has been read by many people.四、被动语态与不定式、情态动词的使用1. 被动语态与不定式:The house needs to be repaired.2. 被动语态与情态动词:The project should be completed by tomorrow.五、被动语态的特殊情况1. 特殊疑问句:Where was the bag found?2. 感叹句:How beautifully the song was sung by the singer!3. 含有两个宾语的句子:We were given a gift by our friends.六、被动语态中的常见错误1. 错误的主语:The book is written by Shakespeare.(改为“The book was written by Shakespeare.”)2. 错误的时态:The photos were taken by me last weekend.(改为“The photos have been taken by me.”)通过对高中英语被动语态知识点的归纳总结,我们可以更好地理解和应用被动语态。
初中英语语法——被动语态用法总结归纳被动语态是英语语法中的重要部分,学好被动语态的用法可以帮助学生更准确地理解和使用英语。
下面是被动语态用法的详细总结归纳。
1.被动语态的构成:被动语态由“助动词be+过去分词”构成,根据时态的不同,助动词be的形式也会发生变化。
如:- 一般现在时:am/is/are + 过去分词- 一般过去时:was/were + 过去分词- 一般将来时:will be + 过去分词- 现在进行时:am/is/are being + 过去分词- 过去进行时:was/were being + 过去分词- 现在完成时:have/has been + 过去分词- 过去完成时:had been + 过去分词2.被动语态的用法:被动语态用来强调动作的承受者(主语)而不是执行者,并且常用于以下情景:2.1当我们不知道或不关心动作的执行者时。
例如:The cake was eaten.(蛋糕被吃了。
)2.2当动作的执行者已知,但我们要强调动作的承受者时。
例如:The house was built by my grandfather.(这座房子是我爷爷建的。
)2.3当我们要避免使用第一人称或第二人称时。
例如:Mistakes were made.(犯了错误。
)3.被动语态的注意事项:在使用被动语态时,需要注意以下几点:3.1表示动作的动词要用过去分词形式。
过去分词的形式有规律变化和不规律变化两种。
如:- 规律变化:原形 + ed,例如:played, watched, called- 不规律变化:需要记忆,例如:born, written, eaten3.2被动句的主语是动作的承受者,通常出现在句子的前面。
如:- 主动语态:I cooked dinner.(我做了晚饭。
)- 被动语态:Dinner was cooked by me.(晚饭是我做的。
)3.3 不及物动词不能构成被动语态。
不及物动词没有宾语,因此不能强调动作的承受者。
七种被动语态形式被动语态是英语中的一种语法结构,用来表达句子的主语是动作的承受者,而不是执行者。
在英语中,被动语态由助动词"be"和动词的过去分词构成。
下面是七种常用的被动语态形式及其示例:1. 一般被动语态(Simple Passive)一般被动语态用于表达一般的情况、事实或真理。
它的结构是:主语+ to be + 过去分词。
示例:- The book is written by a famous author. (这本书是由一位著名作家写的。
)- English is spoken in many countries. (英语在许多国家都是使用的。
)2. 进行被动语态(Continuous Passive)进行被动语态用于表达正在进行的动作。
它的结构是:主语 + to be + being + 过去分词。
示例:- The house is being built by a team of construction workers. (这幢房子正在被一队建筑工人建造。
)- The car is being repaired at the garage. (这辆车正在修理厂修理。
)3. 完成被动语态(Perfect Passive)完成被动语态用于表达已经完成的动作。
它的结构是:主语 + to have been + 过去分词。
示例:- The cake has been eaten by all the guests. (这个蛋糕已经被所有的客人吃掉了。
)4. 一般完成被动语态(Simple Perfect Passive)一般完成被动语态用于表达已经完成的一般情况、事实或真理。
它的结构是:主语 + to have been + 过去分词。
示例:- The job offer has been rejected by many applicants. (这个工作邀请已经被许多申请人拒绝了。
被动语态语法知识点总结一、被动语态的基本结构被动语态是英语中的一种语法结构,通过将动作的承受者置于句子的主语位置,强调动作的接受者而非执行者。
被动语态的基本结构为:be动词(am, is, are, was, were)+过去分词。
例如:Active voice(主动语态):The dog chased the cat.(狗追赶着猫。
)Passive voice(被动语态):The cat was chased by the dog.(猫被狗追赶。
)二、被动语态的用法1. 强调动作的承受者:被动语态可以将动作的承受者放在句子的主语位置,使其成为句子的焦点。
例如:Active voice: He wrote a book.(他写了一本书。
)Passive voice: A book was written by him.(一本书被他写了。
)2. 隐藏执行者:有时候,句子的执行者并不重要或显而易见,这时可以使用被动语态来隐藏执行者。
例如:Active voice: They built this house.(他们建造了这座房子。
)Passive voice: This house was built by them.(这座房子被他们建造了。
)3. 表示客观事实:被动语态常用于描述客观事实或一般真理。
例如:Active voice: People speak English all over the world.(全世界人们讲英语。
)Passive voice: English is spoken all over the world.(英语在全世界都被讲。
)4. 句子的主语是动作的承受者:当动作的承受者比执行者更重要时,可以使用被动语态将其放在句子的主语位置。
例如:Active voice: The car hit the tree.(汽车撞到了树。
)Passive voice: The tree was hit by the car.(树被汽车撞到了。
被动语态知识点总结一、什么是被动语态被动语态是英语中一种重要的语法结构,用于表达主语是动作的承受者而非执行者的情况。
在一个主动语态的句子中,主语是执行动作的主体;而在被动语态中,主语则是接受动作的对象。
例如,主动句“John eats an apple”(约翰吃了一个苹果。
)中,John 是吃这个动作的执行者;而被动句“An apple is eaten by John”(一个苹果被约翰吃了。
)中,an apple 变成了动作的承受者。
二、被动语态的构成被动语态的构成通常是“be +过去分词”。
其中,be 动词根据时态和主语的人称和数进行变化,过去分词则保持不变。
1、一般现在时的被动语态:am/is/are +过去分词例如:The room is cleaned every day(这个房间每天都被打扫。
)2、一般过去时的被动语态:was/were +过去分词例如:The bridge was built last year(这座桥是去年建的。
)3、一般将来时的被动语态:will be +过去分词或 be going to be +过去分词例如:The sports meeting will be held next week(运动会将在下周举行。
)The party is going to be organized by them(聚会将由他们组织。
)4、现在进行时的被动语态:am/is/are + being +过去分词例如:The problem is being discussed now(这个问题正在被讨论。
)5、过去进行时的被动语态:was/were + being +过去分词例如:The machine was being repaired at that time(那时候机器正在被修理。
)6、现在完成时的被动语态:have/has been +过去分词例如:The work has been finished(工作已经完成了。
被动语态知识点总结被动语态是英语语法中的一种重要的句式结构,它能够将动作的承受者置于句子的主语位置,突出动作的接受者和动作本身,常被用于强调行为的影响或者轻描淡写地表达行为的发生。
本文将对被动语态的定义、构成及使用情境等进行深入分析和总结。
一、被动语态的定义被动语态是由动词的过去分词形式与be动词的各种时态连用而构成的。
被动语态的构成包括“be + 过去分词”,其中的be动词需要根据句子的时态和语态进行适当的变换。
例如:- The cake was eaten by the children. (过去时态)- The cake is being eaten by the children. (现在进行时态)- The cake has been eaten by the children. (现在完成时态)- The cake will be eaten by the children. (将来时态)二、被动语态的构成及用法1. 构成被动语态的时态和语态变换如下:- 一般现在时:am/is/are + 过去分词- 一般过去时:was/were + 过去分词- 一般将来时:will be + 过去分词- 现在进行时:am/is/are being + 过去分词- 过去进行时:was/were being + 过去分词- 现在完成时:have/has been + 过去分词- 过去完成时:had been + 过去分词- 情态动词应用:情态动词 + be + 过去分词2. 使用被动语态时需要注意以下几点:- 强调行为接受者:被动语态能够将行为接受者提前置于句子的主语位置,使其成为句子的焦点,而不强调行为的执行者。
例如:- The letter was written by Tom.(行为接受者为主语)- Tom wrote the letter.(行为执行者为主语)- 段落连贯性的考虑:在段落中使用被动语态能够更好地保持句子之间的连贯性,避免过多使用主动语态而显得单调。
被动语态复习A.熟记结构被动语态的结构为“助动词be+及物动词的过去分词p.p”;被动语态的不同时态是通过be的时态变化来表示的,其人称和数方面应与主语保持一致;其具体变化为:一般现在时:am/is/are+p.p.一般过去时:was/were+p.p.一般将来时:shall /will be +p.p.现在完成时:have /has been +p.p.现在进行时:am/is/are+being+p.p.过去将来时:should /would be +p.p.含情态动词的被动结构:情态动词+be+p.p.例如:① Chinese ______ by the largest number of people.A.speak B.is speaking C.speaks D.is spoken② The boy ______ to get supper ready after school.A.were told B.is telling C.was told D.tells③ A lot of new roads ______ built in the west of China.A.must B.must be C.has D.haveB.明确用法被动语态常用于以下两种情况:1.不知道谁是动作的执行者,或者没有必要指出谁是动作的执行者;2.强调动作的承受者;例如:这棵树是那个男孩弄断的;The tree ______ ______ by that boy.C.熟练转换1.将主动语态变被动语态的基本方法为:①将主动语态的宾语作被动语态的主语;②谓语动词变为“be+及物动词的过去分词”,并通过be的变化来表达出不同的时态;③主动语态的主语变为介词by的宾语,组成介词短语放在被动结构中的谓语动词之后;有时by短语可以省略;2.被动语态的一般疑问句是将一个助动词置于主语之前;否定句是在第一个助动词后加not;特殊疑问句的语序为:疑问词+一般疑问句;例如:① You must throw the broken pottery away at once.The broken pottery ______ ______ ______ ______ at once.同义句② Where did they grow vegetables改为被动语态Where ______ vegetables ______D.注意特例将主动语态变被动语态应注意几个特殊情况:1.含双宾语的主动结构变为被动结构时,有两种方法:①将间接宾语变为主语,直接宾语保持不变;②将直接宾语变为主语,间接宾语用介词to或for引导;例如:① He told us a story.变被动语态→We were told a storyby him.或:A story was told to us by him.② Her mother gave her a new pen.变被动语态A new pen ______ ______ ______ her by her mother.2.短语动词的被动语态:在变为被动语态时,要将短语动词视为一个整体,其后的介词或副词不能省去;例如:① This dictionary mustn't ______ from the library.A.take away B.taken away C.are taken away D.be taken away② She will take good care of the children.变被动语态The children will ______ ______ ______ ______ ______ by her.3.含有复合宾语的主动结构变被动结构时,通常将宾语变为被动句的主语,而宾语补足语就成为主语补足语;注意:省略to的不定式作宾补时,不定式符号to必须补上;例如:Someone saw him swim in Qianling Lake yesterday.变被动He ______ ______ ______ swim in Qianling Lake yesterday.4.不定式的被动结构:动词不定式的被动语态为“to be +过去分词”;例如:The radio says a wild animal zoo is to ______ in our city.A.be building B.build C.be built D.built5.以疑问代词开头的疑问句转换成被动句时要注意词序:应将主动句中的疑问代词改为介词by的宾语,但仍然放在句子开头;例如:Who has broken the cup改为被动语态→By whom has the cup been brokenE.注意区别被动语态和过去分词作表语的区别:1含义不同:被动语态强调动作,重点说明动作由谁完成、怎样完成;而过去分词作表语通常用来描写情景,叙述人或事物的特征及所处的状态;试比较:The window is broken.窗子破了;系表结构The window is broken by him.窗子被他打破了;被动语态2用法不同:过去分词作表语时可以被 so,very,too等程度副词修饰,而被动语态则不能用so,very,too 修饰,而需用much,very much,so much,too much修饰;试比较:He was very interested in science.他对科学有极大兴趣;系表结构I was so much surprised at the scene that I didn't know what to do.我被那种场面搞得大吃一惊,不知所措;被动语态F.牢记相关句型教材中与被动语态相关的句型有:1.be covered with被……覆盖2.be made of由……制作发生物理变化 be made from由……制作发生化学变化be made in由某地制造 be made by被某人制造3.be used for被用来…… be used as被当作作为……来使用 be used to do sth.被用来做某事4.It is said that...据说…… It is hoped that...希望…… It is well known that...众所周知……例如:①—Your coat looks nice.Is it ______ cotton —Yes.It's _________Shanghai.A.made of;made by B.made of;made in C.made for;made by D.made for;made in② This machine is used ______ the room w et.A.for keeping B.as keeping C.keep D.to keeping③ 据说在南京长江上又在建一座桥;______ ______ ______ that ______ ______ is being ______ over the Changjiang River in Nanjing.几种特殊的被动语态1. 带不定式的被动语态;The child is sure to be punished for that. 那个孩子肯定会因为那件事受罚的;2. 带介词的动词短语的被动语态;Such a thing has never been heard of. 这件事前所未闻;3. 带副词的动词短语的被动语态;The radio has just been turned off. 收音机刚刚被关上;4. 当sell, wash, clean, run, ride, wear, write等动词若有状语well, easily, badly来修饰时,用主动形式表达被动意义;The pen writes well. 这枝钢笔写字流畅; The book sells well. 这本书很畅销;被动语态专项练习一、选择题1._____ a new library _____ in our school last yearA.

二、被动语态的注意事项
1. 不知道或没有必要说明动作的执行者(不带由by引起的短语)。
如:I haven’t been told about the traffic accident.
2. 动作的承受者是谈话的中心(可带由by引起的短语)。
如:The news has been given out by BBC.
3. 不愿说出动作的执行者是谁。
如:It’s generally considered that teaching is as much an art as it is a
science.
三、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。
如:This kind of robot can be used to do some housework.
2. 感官动词或某些使役动词使用省略to的动词不定式,主动语态中不带
to,但变为被动语态时须加上to。
如:The little boy was made to do a difficult job.
He was seen to enter the classroom.
3. 一些动词短语用于被动语态时,动词短语应当看作一个整体,而不能丢掉
其中的介词或副词。
如:The child was taken care of by his grandmother.
4. 完成进行时和将来进行时都不存在被动语态,如确需使用被动形式则用完
成时态或一般时态代替。
We have been talking about the matter for an hour.
→The matter has been talked about for an hour.
We will be talking about the matter this evening.
→The matter will be talked about this evening.
三、非谓语动词的被动语态
1. 当不定式动词与其逻辑主语之间是动宾关系时,不定式要用被动语态形式。
其构成形式为to be done或to have been done。
如:It was going to be tested out by Larry’s wife, Claire.
注意:当不定式作表语,主语又是不定式的动作的承受者时,通常用主动形式表示被动。
如:The math problem is rather difficult to work out.
2. 当动词-ing 形式的逻辑主语是动作的承受者时,就要用动词-ing形式的被动
语态being done。
动词-ing形式的完成式的被动语态是having been done,强调这一被动动作发生在谓语动词动作之前。
如:No one is fond of being made fun of in public.
My cousin was very unhappy for not having been invited to the party.
3. 动词need, want, require后接动名词的主动形式表示被动意义。
如:
The flowers need / want / require watering three times a week.
4. 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。
如:
The picture-book is well worth reading.
= The picture-book is worthy to be read.
5. 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。
如:
I have a lot of things to do this afternoon.
比较:I’ll go to the post office. Do you have a letter to be posted?
6. 在某些“形容词+ 不定式”作表语或宾语补足语的结构中,句子的主语或宾语又是动词不定式的逻辑宾语时,这时常用不定式的主动形式表达被动意义。
这些形容词有nice,easy,fit,hard,difficult,important,impossible,pleasant,interesting等。
如:This problem is difficult to work out.
7. 在too … to … 结构中,不定式前面可加逻辑主语,所以应用主动形式表示被动意义。
如:This book is too expensive (for me) to buy.
8. 在there be …句型中,当动词不定式修饰名词作定语时,不定式用主动式作定语,重点在人,用被动形式作定语,重点在物。
如:There is no time to lose (to be lost).
9. 在be to do结构中的一些不定式通常应用主动表主动,被动表被动。
然而,下列动词rent, blame, let等仍用不定式的主动形式表示被动意义。
如:Who is to blame for starting the fire?
四、被动形式表示主动意义
1. 有些动词形式上是被动的,但含义上却是主动的,主要有以下两种情况:
如果谓语部分是“及物动词+ 反身代词”时,其被动语态多表示主动的意义。
常见的这类动词有dress, seat, lose等。
如: He was dressed in a dark blue suit when I saw him for the first time.
→He dressed himself in a dark blue suit when I saw him for the first time.
2.英语里还有许多固定搭配,其形式上是被动的,却表示主动含义。
常见的
这类短语有:be gone“不见了”,be engaged to sb“和……订婚”,
be married to sb“和……结婚”,be concerned about“关心”等。
如:The boss should have been concerned more about the health of the workers.。
