初中英语被动语态用法小结

初中英语被动语态用法小结[1]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。

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. 英语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”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speak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＋spoken

一般过去时：was／were＋spoken

一般将来时：will／shall be＋spoken

现在进行时：am／is／are being＋spoken

过去进行时：was/were being＋spoken

现在完成时：have／has been＋spoken

过去完成时：had been + spoken

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。（不知道电脑是谁偷的）

This bridge was founded in 1981.这座桥竣工于1981年。

（2）强调动作的承受者，而不强调动作的执行者。

例如：The glass was broken by Mike.玻璃杯是迈克打破的。

This book was written by him.这本书是他写的。

Your homework must be finished on time.你们的家庭作业必须及时完成。

四、主动语态变被动语态的方法

（1）把主动语态的宾语变为被动语态的主语。

（2）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.

五、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。

We can repair this watch in two days.

This watch can be repaired in two days.

They should do it at once.

It should be done at once.

六、特殊情况

1.He made the boy work for two hours yesterday.

The boy was made to work by him for two hours yesterday.

2.Mother never lets me watch TV .

初中英语介词用法总结

初中英语介词用法总结 介词(preposition)：也叫前置词。在英语里，它的搭配能力最强。但不能单独做句子成分需要和名词或代词（或相当于名词的其他词类、短语及从句）构成介词短语，才能在句中充当成分。 介词是一种虚词，不能独立充当句子成分，需与动词、形容词和名词搭配，才能在句子中充当成分。介词是用于名词或代词之前，表示词与词之间关系的词类，介词常与动词、形容词和名词搭配表示不同意义。介词短语中介词后接名词、代词或可以替代名词的词（如：动名词v-ing）.介词后的代词永远为宾格形式。介词的种类： （1）简单介词：about, across, after, against, among, around, at, before, behind, below, beside, but, by, down, during, for, from, in, of, on, over, near, round, since, to, under, up, with等等。 （2）合成介词：inside, into, outside, throughout, upon, without, within （3）短语介词：according to, along with, apart from, because of, in front of, in spite of, instead of, owing to, up to, with reguard to （4）分词介词：considering, reguarding, including, concerning 介词短语：构成 介词+名词We go to school from Monday to Saturday. 介词+代词Could you look for it instead of me? 介词+动名词He insisted on staying home. 介词+连接代/副词I was thinking of how we could get there. 介词+不定式/从句He gives us some advice on how to finish it. 介词的用法： 一、介词to的常见用法 1.动词+to a)动词+ to adjust to适应, attend to处理；照料, agree to赞同,

初中英语被动语态专项练习

被动语态 一、被动语态的定义 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。如：We speak English. 句子中主语we是speak（讲）这个动作的执行者。 被动语态表示主语是动作的承受者。如：English is spoken by them. 句子中主语English是speak（讲）这个动作的承受者，即英语被讲。被动语态相当于汉语的“被”字句。 二、被动语态的构成 英语的语态是通过动词形式的变化来体现。 被动语态的构成是：主语+be+动词的过去分词 人称、数和时态的变化是通过be的形式变化来表示。 1、记住下面几种时态的被动语态的构成： 一般现在时：主语+am/is/are+过去分词（+by+动作的执行者）（强调动作的执行者） 一般过去时：主语+was/were+过去分词（+by+动作的执行者）（强调动作的执行者） 一般将来时：主语+will/shall+be+过去分词（+by+动作的执行者）（强调动作的执行者） 现在进行时：主语+am/is/are+being+过去分词（+by+动作的执行者）（强调动作的执行者）

过去进行时：主语+was/were+being+过去分词（+by+动作的执行者）（强调动作的执行者） 现在完成时：主语+have/has+been+过去分词（+by+动作的执行者）（强调动作的执行者） 2、含有情态动词的被动语态 主语+情态动词+be+动词的过去分词（+by+动作的执行者）（强调动作的执行者） 三、被动语态的用法 1、怎样确定该用被动语态？ （1）不知道或者没有必要说明动作的执行者。 强调动作的承受者，而不强调动作的执行者。 我们在做题时要注意：如果主语能执行这个动作，就用主动语态；主语不能执行动作，反而要被动作去执行，这时就用被动语态。 2、用被动语态要注意两个问题 （1）不管是把主动语态变被动语态还是把被动语态变主动语态都要保持时态一致 （2）在主动语态中make,see,let等省to的在被动语态中要加上to. 3、不能使用被动语态的情况： （1）不及物动词不能用于被动语态，如：happen,take place,last,cost,change，begin等 （2）当直接宾语是反身代词时，不能用被动语态 连系词无被动，而是用主动形式表示被动意义如：

初中英语动词的主动语态和被动语态讲解

动词的主动语态和被动语态【用法讲解】考试要求： 中考要求掌握：动词的主动语态和被动语态区别与使用，不同时态的被动语态形式及情态动词的被动语态形式。英语动词有两种语态：主动语态和被动语态，主动语态表示句子的主语是谓语动作的执行者；被动语态是表示句子的主语是谓语动作的承受者。 如：We often clean the blackboard.（我们是擦黑板的执行者即主动语态）The blackboard is often cleaned by us.（黑板是clean的承受者即被动语态）。 1.被动语态的结构 一般现在时：am / is / are +及物动词的过去分词 一般过去时：was / were +及物动词的过去分词 一般将来时：will / shall be +及物动词的过去分词 现在完成时：have / has been +及物动词的过去分词 现在进行时：am / is / are being +及物动词的过去分词 过去完成时：had been +及物动词的过去分词 如：Youare wantedon the phone.有你的电话。 Chinawas liberatedin 1949. 1949年中国解放。 The problemwill be discussedtomorrow. 明天将对这个问题进行讨论。 Not a book in the libraryhas been taken away. 图书馆里没有一本书被人拿走。 My bikeis being repaired.我的自行车正在修理。

The bookhad been borrowedwhen I got to the library.我到了图书馆时,那本书已经借出去了。 2.主动语态与被动语态的转换 （1）把主动语态的宾语变为被动语态的主语。（2）把谓语变成被动结构（be＋过去分词），根据被动语态句子里主语的人称和数，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。 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. 3.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。 We can repair this watch in two days. →This watch can be repaired in two days. They should do it at once. →It should be done at once. 4.含有双宾语的主动语态变为被动语态 主动语态:主语+谓语动词+间接、直接宾语+其他

初中英语被动语态的讲解

初中英语被动语态的讲解 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 to start. 8）had been done 过去完成时例By the end of last year, another new gymnasium had been completed in Beijing. 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，否定句主语+be not+过去分词，一般疑问句Be+主语+过去分词，特殊疑问句疑问词+be+主语+过去分词。 3.被动语态的特殊形式 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) 双宾语结构。主动结构中的一个宾语变为主语，另一宾语仍

英语被动语态用法详解 一、单项选择被动语态 1．The classroom ________ by students every day.

义务教育基础课程初中教学资料 被动语态小结及练习 一、被动语态的用法： 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 1. 一般现在时的被动语态：is / am / are + 及物动词的过去分词 Our classroom is cleaned everyday. 2. 一般过去时的被动语态：was / were + 及物动词的过去分词 A new shop was built last year. 3. 现在完成时的被动语态：has / have + been + 及物动词的过去分词 This book has been translated into many languages. 4. 过去完成时的被动语态: had been +及物动词的过去分词 The dish had been eaten up when I got there. 5. 一般将来时的被动语态：will+ be + 及物动词的过去分词 A new hospital will be built in our city. 6. 含有情态动词的被动语态：情态动词+ be + 及物动词的过去分词 Young trees must be watered often. 7. 现在进行时的被动语态：am / is / are + being + 及物动词的过去分词 Uncle Wang is mending my bike now. → My bike is being repaired by Tom now. 8. 不定式的被动语态：to + be + 及物动词的过去分词 There are two books to be read. →There are twenty more trees to be planted. 二、怎样把主动语态改成被动语态? 把主动语态改为被动语态非常简单，可以遵循以下几个步骤： 1. 先找出谓语动词； 2. 再找出谓语动词后的宾语； 3. 把宾语用作被动语态中的主语； 4. 注意人称、时态和数的变化。 例：1. Bruce writes a letter every week. →A letter is written by Bruce every week. 三、使用被动语态应注意的几个问题： 1. 不及物动词无被动语态。What will happen in 100 years. 2. 有些动词用主动形式表示被动意义。 This pen writes well. His novel sells well. 他的小说畅销。 3. 感官动词或使役动词使用省略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 。 例：make somebody do something → somebody+ be +made to do something 4. 如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定 He gave me a book.→ A book was given to me by him. 5. 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。 We can’t laugh at him. →He can’t be laugh at by us. 注意:

英语被动语态用法

语态篇——常见与不常见的被动 [提问]在下面这个句子中，那些部分为被动语态“I had not originally been scheduled to work this day but I was extremely pleased when I was asked to help out at the last minute, for it would be one of the most memorable days of the games. (Experiencing English Integrated Book Page120)” 答：要分析上面这个句子，并划出相应的被动语态部分，首先要清楚地了解什么是被动语态和被动语态的结构。 在学中，语态是针对动词而言的一种形式，描述句子中和参与此动作的之间关系。语态分为主动Active Voice和被动Passive Voice两种。当主语是动作的发起者（或之一）时，称为主动语态；如果主语为动作的承受者时，称为被动语态。例如：“猫吃老鼠。”这句话是主动语态；而“老鼠被猫吃。”则是被动语态。 一点意见，我觉得这些语法太简单了 被动语态强调动作的对象或动作本身，句中主语是动作的受动者。分析句子时找到主语和谓语动词，如果主语并非主动行为，而是接受动作，是动作指向的对象，那么该句就是被动句。被动语态的基本构成为： be动词+及物动词过去分词。其中be动词随着句子的不同时态发生相应变化，并要注意随主语人称、单复数变化而使用正确形式。 1）一般现在时：am／is／are＋V-ed 2）一般过去时：was／were＋V-ed
