初三英语被动语态知识点整理
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) 一般现在时例Visitors are requested not to touch the exhibits.
2）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.
3）am/is /are being done现在进行时例A new cinema is being built here．4）was/were done一般过去时例I was given ten minutes to decide whether I should reject the offer.
5）had been done 过去完成时例By the end of last year, another new gymnasium had been completed in Beijing.
6）was/were being done 过去进行时例A meeting was being held when I was there.
7）shall/will be done 一般将来时例Hundreds of jobs will be lost if the factory closes. 8）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.
9）shall/will have been done 将来完成时（少用）例The project will have been completed before July.
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，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.
5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。例The meeting is to be put off till Friday.
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
一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“It＋be＋过去分词＋that从句”或“主语＋be＋过去分词＋to do sth.”。有：It is said that…据说,It is reported that…据报道，It is believed that…大家相信，It is hoped that…大家希望，It is well known that…众所周知，It is thought that…大家认为，It is suggested that…据建议。例It is said that the boy has passed the national exam. （＝The boy is said to have passed the national exam. ）
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，catch，clean，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：happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等以主动形式表示被动意义。
例How do the newspapers come out? 这些报纸是如何引出来的呢？
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, book, 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 五、非谓语动词的主动形式表被动意义

初三英语被动语态
动词的语态 动词的语态用以说明句中主语和谓语的关系。如果主语是动作 的执行者，动词形式为主动语态；如果主语是动作的承受者，动词形式为被动语态。被动语态与主动语态一样，也是中考的重要考点之一，分值约占中考总分值的8%。考查的内容主要有被动语态的用法、被动语态的结构、被动语态与主动语态的相互转化、不能使用被动语态的句型等。考查的形式包括用所给的动词的适当形式填空、单项选择、句型转换、完型填空、阅读理解等。 1．被动语态的构成 被动语态和主动语态一样，也有各种时态形式，其基本结构是，be+过去分词。被动语态的谓语和主语在逻辑上是动宾关系。 初中阶段常见的几种时态的被动语态： (1)一般现在时：am/is /are+过去分词 History is made by people.历史是由人民创造的。 (2)一般过去时：was/were+过去分词 The book was written by him.这本书是他写的。 The radio wasn’t mended last week.上周这台收音机没被修理。 （3）一般将来时：a. am/is/are going to be+过去分词； b.will/shall be +过去分词。 Some trees will be planted this spring.今年春天将要植一些
树。 Shall we be asked to study English?会不会要我们去学英语？（4）含有情态动词的被动语态：情态动词+be+过去分词 The man must be sent to hospital.这个人必须被送往医院。 （5）现在进行时：am/is/are+being+过去分词 Some trees are being planted by the students. Is a few factory eing built in your village? (6)现在完成时：have/has been +过去分词 She is unhappy because she hasn’t been asked to the party.她不高兴，因为她没有被邀请去参加聚会。 被动语态的基本用法： （1）不知道动作的执行者是谁，或没有必要指出动作的执行者时用被动语态。 Letters are collected at eight every morning.信件每天 早上八点收取。 The glass was broken last night.玻璃被打坏了。 （2）为了强调或突出动作的承受者时。例如： The plan has already been made.计划已经制定好了。 The bag was taken away by his sister.那个包被他姐姐拿 走了。 （3）在上下文中，为了使句子衔接更紧密（结构的需要）时要用被动语态。

九年级英语英语被动语态讲解及练习
英语被动语态讲解及练习 一、什么是被动语态？ 英语中时态很多，但语态不多，只有两种，即：主动语态和被动语态。所谓“被动语态”，相当于中文中常说的“被……”、“由……”的句式，如：“他的自行车被偷了。”，“这座楼房是由他们建造的。” 二、被动语态的结构 那么，英语中被动语态是怎么样构成的呢？请看下面的例句（注意划线部分）： His bicycle was stolen. The building has been built in 2000. 通过上面的例句，可以看出，“被动语态”的构成是： be + 过去分词+ (by+动作执行者) 三、被动语态的运用 什么情况下要用被动语态呢？一般地说，有下面几种情况： （1）不知道谁是动作的执行者或没有必要。例如： Paper is made from wood. （纸是由木材生产出来的。） The house is quite old. It was built in 1950. （这座房子太旧了。它是1950年建成的。） He was wounded in the fight. （他在战斗在受伤了。） Electricity is used to run machines. （电是用来开动机器的。） （2）需要强调动作的对象时。例如： Calculator can't be used in the maths exam.
（计算器不能用于数学考试。） Books and newspapers in the reading room mustn’t be taken away. （阅览室的书籍和报纸不准带走。） He was awarded first prize in that contest. （他在比赛中获得了第一。） （3）为了使语气婉转，避免提到是谁做的这件事。例如： The construction of the new lab must be completed by the end of next month. （新实验室必须在下个月底前完工。） 四、各种时态的被动语态举例 一般地讲，被动语态可用于英语的各种时态。为了能准确地运用被动语态，重点是要掌握be动词的各种时态变化。各种时态的被动语态举例如下： 1、一般现在时的被动语态. am / is / are + 动词的过去分词 Our classroom is cleaned every day. This car is made in China. 2、一般过去式的被动语态: was / were + 动词的过去分词 His desk was cleaned just now. The station was built in 1928. 3、现在进行时的被动语态: am / is / are + being + 动词的过去分词 A new factory is being built in our city now. Some trees are being cut down in the park. 4、过去进行时的被动语态: was / were + being + 动词的过去分词
初三英语语法知识点归纳
初中英语语法速记口诀大全 很多同学认为语法枯燥难学，其实只要用心并采用适当的学习方法，我们就可以愉快地学会英语，掌握语法规则。笔者根据有关书目和多年教学经验，搜集、组编了以下语法口诀，希望对即将参加中考的同学们有所帮助。 一、冠词基本用法 【速记口诀】 名词是秃子，常要戴帽子， 可数名词单，须用a或an， 辅音前用a，an在元音前， 若为特指时，则须用定冠， 复数不可数，泛指the不见， 碰到代词时，冠词均不现。 【妙语诠释】冠词是中考必考的语法知识之一，也是中考考查的主要对象。以上口诀包括的意思有：①名词在一般情况下不单用，常常要和冠词连用；②表示不确指的可数名词单数前要用不定冠词a或an，确指时要用定冠词the；③如复数名词表示泛指，名词前有this，these，my，some等时就不用冠词。 二、名词单数变复数规则 【速记口诀】 单数变复数，规则要记住， 一般加s，特殊有几处： 末尾字母o，大多加s， 两人有两菜，es不离口， 词尾f、fe，s前有v和e； 没有规则词，必须单独记。 【妙语诠释】①大部分单数可数名词变为复数要加s，但如果单词以/t?蘩/、/?蘩/、/s/发音结尾(也就是单词如果以ch，sh，s，x等结尾)，则一般加es；②以o结尾的单词除了两人(negro，hero)两菜(tomato，potato) 加es外，其余一般加s；③以f或fe结尾的单词一般是把f，fe变为ve再加s；④英语中还有些单词没有规则，需要特殊记忆，如child—children，mouse—mice，deer—deer，sheep—sheep，Chinese—Chinese，ox—oxen，man—men，woman—women，foot—feet，tooth —teeth。 三、名词所有格用法 【速记口诀】 名词所有格，表物是“谁的”， 若为生命词，加“’s”即可行， 词尾有s，仅把逗号择； 并列名词后，各自和共有， 前者分别加，后者最后加； 若为无生命词，of所有格， 前后须倒置，此是硬规则。 【妙语诠释】①有生命的名词所有格一般加s，但如果名词以s结尾，则只加“’”；②并列名词所有格表示各自所有时，分别加“’s”，如果是共有，则只在最后名词加“’s”；③
初三英语知识点总结有哪些
初三英语知识点总结有哪些 ----WORD文档，下载后可编辑修改---- 下面是小编收集整理的范本，欢迎您借鉴参考阅读和下载，侵删。您的努力学习是为了更美好的未来！ 初三英语知识点总结英语名词分可数的和不可数两种。可数名词指一般动物和事物，如“Man/ friend/ driver/ student/ dog/ cat/ boat/ egg/ gun/ hand/ head/ lamp/ road/ table/ car ”等等。 可数名词有两个数，即单数和复数。单数名词可以和不定冠词“ a/ an”或其他名词限定词(determiners)连用;复数名词可以和数目词，如“many/ a few/ some/ a lot of”等连用。 不可数名词指物质名词(material nouns)和抽象名词( abstract nouns)，如：“air/ butter/ grass/ money/ sand/ water/ carefulness/ joy/ peace”等等。不可数名词可以和数量词，如“much/ a little/ little/ a great amount of”等连用。不可数名词只有单数，没有复数“-s”的形式。 有些人对名词数的概念不很清楚，对数目词(expressions of number)和数量词(expressions of quantity)也有些混乱，结果把数目词用在不可数名词之前或随意在不可数名词后面加上复数词尾“-s”，这些都是语法上的错误。例如： ① Our workshop has ordered some n ew equipments from Germany. 虽然有些人把 equipment(配备)当成可数名词，但是它是不可数的，不可有“-s”。 ② My teacher gave me some sound advices. 应该是“advice”。 ③ Do you have any special informations for me? “Information”才对。 ④ Most furnitures in my house are made of wood. 应该是“furniture......is......” ⑤ Today, I have many new works to do. 必须是“a lot of new work”才是。 ⑥ Don't walk on the grasses. 应该用“grass”。

初中英语被动语态讲解原版 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 例Visitors are requested not to touch the exhibits. 2） 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. 3） am/is /are being done 现在进行时 例A new cinema is being built here． 4） was/were done 一般过去时 例I was given ten minutes to decide whether I should reject the offer. 5） had been done 过去完成时 例 By the end of last year, another new gymnasium had been completed in Beijing.[少儿英语口语的提高，如果方法对还是很快的，最好的方法就是让他沉浸在一 个英语的环境中，现在最多人用的类似UIABC 这样的外教一对一教学平台，在一对一的教学中 建立一个纯正的说英语环境，15元/节的价格，也是还算比较经济的。] 6） was/were being done 过去进行时 例A meeting was being held when I was there. 7） shall/will be done 一般将来时 例Hundreds of jobs will be lost if the factory closes. 8） 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. 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。 例Someone saw a stranger walk into the building. 可改为A stranger was seen to walk into the building. 5) 有些相当于及物动词的动词词组，如“动词＋介词”，“动词＋副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能 省略。
