初中被动语态讲解及配套练习
一、主动语态与被动语态的概念：
英语动词的语态有两种：⑴主动语态：表示主语是动作的执行者
⑵被动语态：表示主语是动作的承受者(常常没在有必要指出动作的执行者情况下使用) 例：They speak English. （主动语态）
主谓宾
English is spoken by them. （被动语态）
主谓介词短语
注：☆及物动词有被动语态，不及物动词必须带有介词才可以有被动语态。
例：⑴We listen to the teacher carefully in class.
主谓宾
→The teacher is listened to by us carefully in class.
主谓介词短语
⑵Ｗe laughed at him .
→He was laughed at by us.
二、被动语态的结构与用法：
㈠结构：be +done (过去分词)
被动语态中的be为助动词，无意义。be可能是am , is , are也可能是was ,were或原形be。
注：☆被动语态的时态是由be的时态决定的，be是什么时态，全句就是什么时态，be 后面的过去分词不变。
㈡用法：
例：①Ｈistory is made by the people. (一般现在时)
②Ｔhe cars were made in Tianjing in 1995. (一般过去时)
③The tree will be cut down next year.(一般将来时)
④Ｔhe room must be kept clean.（含有情态动词的被动语态）
⑤The door is being opened.（现在进行时）
⑥The film has been seen by me.（现在完成时）
注：我们初中主要掌握前面四种的用法
时态动词的被动形式例句
一般现在时is done He is asked to do this.
一般过去时was done The story was told by her mother.
一般将来时will be done The problem will be discussed tomorrow. 现在进行时is being done The novel is being written.
过去进行时was being done At that time the desk was being made.
现在完成时has been done The house has been built.
过去完成时had been done They said that their work had been finished. 过去将来时would be done He said the trees would be planted soon.
三、被动语态的各种句型：
１、Ｔhe song is liked by young people. (肯定句)
２、Ｔhe song isn’t liked by young people（否定句）
３、Is the song liked by young people ?（一般疑问句）
４、Who is the song liked by ?=By whom is the song liked?（特殊疑问句）
四、主动语态改被动语态的方法：
方法分为三步：⑴把原句中的宾语改成主语
⑵动词改为变动形式be done(同时注意时态)

被动语态 一．概念： 英语动词有两种语态，即主动语态(The Active Voice)与被动语态（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。 例：1. They make trains in Xi’an. >> Trains are made in Xi’an by them. 2.Xm beats Xx evey day. >> Xx is beaten by Xm every day. 二．构成 be + done (p.p.--及物动词的过去分词） 一般现在时—— am／is ／are + v.p.p. 一般过去时—— was／were +v.p.p. 一般将来时—— will be／be going to be + v.p.p. 过去将来时——would be/was,were going to be + v.p.p 现在进行时——am/is/are being + v.p.p. 过去进行时——was/were being+ v.p.p. 现在完成时—— have/has +been+ v.p.p 情态动词—— aux.v. (must／can／could／may…) + be + v.p.p. 三．被动语态的使用 1. 当我们不知道或没有必要指出谁是动作的执行者时； 例：1. His car was stolen last night. 2. Basketball is played in most countries. 2. 动作的承受者是谈话的中心（常由by引起） 例：1. A lot of articles (that) we have learned were written by Lu Xun. 四．不用被动语态的情况 1. 某些及物动词+ adv表主动，特别是后加副词（如well， easily等）时。主动语态有被动含义，这类动词常见的有sell，write，wear，wash，photograph, clean, cook, cut 例：1. This book sells well. 2.Your pen writes really well/smoothly. 3.This dress (that) my mom bought for me wears well 4.She does not photograph well. 5.The cheese doesn’t cut easily. It’s too soft. 句子是主谓结构时，不用被动语态。常见的谓语动词有：happen, take place, (dis)appear, rise, break out, come about, come true, come out, run out, turn out 例：1. A traffic accident happened just now. 2. Great changes are taking place in my hometown. 3. He disappears. 4. When a gay person comes out, they let people know that he is a gay. 3. 连系动词无被动：感官系动词：look、feel、sound、smell、taste “表变化的系 动词”：become、grow、turn、fall、get “表保持的系动词”：keep, reamain, stay ④ prove + 形容词，名词或不定式 五．注意

初中被动语态详细讲 解
语法专练---被动语态 一、语态概述 我吃了一个苹果，那现在苹果怎样了？苹果被我吃了。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。 及物动词---本身意义不完整，后必须带宾语，有些还可以带双宾。 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。现以eat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＋eaten 一般过去时：was／were＋eaten 一般将来时：will/shall/be going to be＋eaten 过去将来时：would/should/be going to be＋eaten 现在进行时：am／is／are being＋eaten 过去进行时：was／were being＋eaten 现在完成时：have／has been＋eaten 过去完成时：had been＋eaten 歌诀是：被动语态be字变，过去分词跟后面。 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 book was published in 1981.这本书出版于1981年。（没有必要或说出出版者） (2)强调动作的承受者，而不强调动作的执行者。 例如：The window was broken by mike.窗户是迈克打破的。 This book was written by Lunxun.这本书是他写的。 Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保 证。 歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。 (3) 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. （一个主语 就够了） 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)。
现在进行时态教学设计 一．教学内容：七年级下册Unit6 1．词汇：carry, eat, make, paint, put, …. 2．句型：What are you doing? I’m\we’re …. What are they doing? They’re …. What is he\she doing? He’s\She’s …. 二．教学目标： *认知目标：1能听懂、会说、会读、会拼写五个表示动作的单词stand, sit, sleep, jump, run, walk. 2 初步掌握现在进行时态的概念、构成、用法等。 *能力目标：能正确运用现在进行时态询问别人正在做什么，培养学生用英语交际、用英语解决实际问题的能力。 *情感与策略、文化等方面目标： 1．关注学生在学习过程中积极愉悦的情感体验。培养学生自信开口、积极思维的习惯。 2．养成学生积极自主地体验、实践、参与、合作的学习方式。 3．引导学生用丰富多采的课余活动构建自己健康愉快的生活方式。 三、教学重难点： 1.重点：能听懂、会说、会读、会拼写五个表示动作的单词stand, sit, sleep, jump, run, walk；掌握句型What are you doing? I’m\we’re ….What are they doing? They’re ….What is he\she doing? He’s\She’s …. 2.难点：现在进行时态的理解、运用；现在分词的常见构成形式及读音。 四、教学准备：多媒体课件、单词卡片、习题卷 五、教学过程： Step 1 : Warming up 1.Greetings T: Class begins ! Good morning, boys and girls . S: Good morning, Miss Miao . T: How are you this morning? S: Fine , thanks .And you ? T: I’m very well .Because I have many new friends here, you make me very happy. Thank you .Sit down ,please ! (设计意图：课的开始以师生间亲切的问候导入，师生情感互融，迅速营造温馨愉悦的教学氛围,帮助师生以良好的精神状态进入课堂教学。) T: Boys and girls, wh 2．Free talk I’m happy, I like singing. Please listen. 师唱“You are my sun shine, my only sun shine …”I like singing. What do you like? S1: I like swimming. T: Oh, a brave boy！I can’t swim. T: Do you like swimming? S2: No, I don’t. I like dancing. T: You like dancing！Can you dance for us? S2:Yes.(该生简单跳几个动作)
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 …… to him by Mary. for her by her father. 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)

初中被动语态语法讲解 (一) 语态分类 英语动词有两种语态，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如： 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。不同时态的被动语态，列表如下：一般现在时：am / is / are + done 一般过去时：was / were + done 一般将来时：shall / will + be done 一般过去将来时：should / would + be done 现在进行时：am / is / are + being + done 过去进行时：was / were + being + done 现在完成时：have / has + been + done 过去完成时：had + been + done 将来完成时：shall / will + have been + done 过去将来完成时：should / would + have been + done ［注］被动语态没有将来进行时和过去将来进行时。 (三)常见的八种时态中的被动语态 1. 一般现在时： (1)People grow rice in the south of the country. Rice is grown in the south of the country. (2)The school doesn't allow us to enter the chemistry lab without a teacher. We are not allowed to enter the chemistry lab without a teacher. 2. 一般过去时： (1)They agreed on the building of a new car factory last month. The building of a new car factory was agreed on last month. (2)The students didn't forget his lessons easily. His lessons were not easily forgotten 3. 一般将来时： (1)They will send cars abroad by sea. Cars will be sent abroad by sea. (2)They will give plenty of jobs to school-leavers. Plenty of jobs will be given to school-leavers. 4. 过去将来时： (1)The manager said they would complete the project by the end of the year. The manager said the project would be completed by the end of the year. (2) The workers told me they would mend the car as soon as possible. The workers told me that the car would be mended as soon as possible. 5. 现在进行时：
被动语态 一、概念： 语态是动词的一种形式，它表示主语和谓语的关系。语态有两种：主动语态和被动语态。如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。 二、主动句变为被动句的步骤： 1.把原主动句中的宾语变为被动句的主语 2.把动词变为被动形式即be +过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。 3.原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。 4.其它的成分（定语、状语）不变。 三、被动语态的用法： 1. 一般现在时的被动语态构成：is / am / are + 及物动词的过去分词 We clean our classroom every day. My mother asks me to study hard. 2. 一般过去时的被动语态构成：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构成：has / have + been + 及物动词的过去分词 This book has been translated into many languages. Many man-made satellites have been sent up into space by many countries. 4. 一般将来时的被动语态构成：will+ be + 及物动词的过去分词 A new hospital will be built in our city. Many more trees will be planted next year. 5. 含有情态动词的被动语态构成：情态动词+ be + 及物动词的过去分词 Young trees must be watered often. Your mistakes should be corrected right now. The door may be locked inside. Your homework can be handed in tomorrow. 6. 现在进行时的被动语态构成：am / is / are + being + 及物动词的过去分词 7. 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. 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 see somebody do something→somebody +be +seen to do something A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by. The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 4. 如果是接双宾语的动词改为被动语态时，可以使用直接宾语也可以使用间接宾语作被动语态句子的主语。使用直接宾语(物)作主语时，要在动词后加上介词，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. He showed me a ticket. →A ticket was shown to me by him. My father bought me a new bike. →A new bike was bought for me by my father.
语法专练---被动语态 一、语态概述 我吃了一个苹果，那现在苹果怎样了？苹果被我吃了。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。 及物动词---本身意义不完整，后必须带宾语，有些还可以带双宾。 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。现以eat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＋eaten 一般过去时：was／were＋eaten 一般将来时：will/shall/be going to be＋eaten 过去将来时：would/should/be going to be＋eaten 现在进行时：am／is／are being＋eaten 过去进行时：was／were being＋eaten 现在完成时：have／has been＋eaten 过去完成时：had been＋eaten 歌诀是：被动语态be字变，过去分词跟后面。 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 book was published in 1981.这本书出版于1981年。（没有必要或说出出版者） (2)强调动作的承受者，而不强调动作的执行者。 例如：The window was broken by mike.窗户是迈克打破的。 This book was written by Lunxun.这本书是他写的。 Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证。 歌诀：谁做的动作不知道，说出谁做的没有必要；动作承受者需强调，被动语态运用到。 (3) 为了更好地安排句子。 例The well-known person got on the bus and was immediately recognized by people. （一个主语就够了） 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. 歌诀是：宾变主，主变宾，by短语后面跟。谓语动词变被动，be后“过分”来使用。 五、含有情态动词的被动语态
专项复习:被动语态 （Revision of the Passive Voice） 【复习目标】1.熟悉常用时态的被动语态； 2.在题目中正确理解和运用被动语态 【复习重点】常用时态的被动语态 【复习难点】各个考点 【复习步骤】 一．基本概念复习 1.总结概念：谓语动词的执行者作主语，用语态；若谓语动词的承受者作主语，用语态。 2.总结结构：be+ done (be动词可以随时态、人称数的变化而变化) 二．考点复习 考点一：含有可以带双宾语的动词的被动语态结构 1.在下列动词后，通常在间接宾语前用介词to: bring , give , lend , offer , pass , show , take , tell , send , teach等 2.在下列动词后，一般在间接宾语前用介词for buy , make , get , choose , cook , sing等
考点二：在感官动词see , watch , hear , notice , feel 及使役动词have , let , make等词后作宾语补足语的动词不定式都不带to , 但变被动语态后要还原上to 。 考点三：含有动词短语的被动语态，切记不要将短语中的介词或副词忘掉或省略。 考点四：有些谓语动词的主动形式表示被动意义 1.某些用来描述主语特征的不及物动词，常用其主动形式表达被动意义，这时主语通常是物。eg: sell , wash , read , write , 等 ?The books well． A. were sold B. sell C. have sold D. are being sold ?This coat _____ easily． A. has washed B. was washed C. washes D. is washed 2.表示状态特征的连系动词+ adj. / n.用主动形式表被动意义。eg: look , sound , feel , smell , taste 等 ①The steel(钢铁) _____ cold． A. is felt B. was feeling C. feels D. is being felt ②His plan _____ good． A. has sounded B. is sounding C. is sounded D. sounds 3.表示“发生，进行”的不及物动词用主动形式表被动意义。eg: happen , take place , come out , come true等 考点五：含有被动意义的“have / get + 宾语+ done” 考点六：表示客观的说明常用“It’s + done+…..” 据说….. 据报道……. 众所周知……. 据推测说….. 大家都相信…… 考点七：某些动词可以用-ing 形式表被动意义 三．练习题 (一)选择题(A)
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.

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。
