初中中的被动语态用法详解
初中中的被动语态用法详解被动语态是英语中一个常用的语法结构，包含了及物动词的被动形式。
初中阶段，学生们需要逐渐掌握被动语态的用法。
本文将详细介绍初中中的被动语态用法。
一、被动语态的基本构成被动语态的基本构成由be动词的适当形式+过去分词构成。
be动词的形式根据句子的时态和主语的人称而定。
过去分词则根据动词的一般过去时的变化规则。
例如：- The car is repaired.（句子时态：一般现在时）- The car was repaired.（句子时态：一般过去时）- The car will be repaired.（句子时态：一般将来时）二、被动语态的用法1. 没有明确的执行者在被动语态中，我们强调动作的接受者而非执行者。
有时，在句子中并没有明确指出执行动作的人或事物。
例如：- The window was broken.（窗户被打破了。
）- The book will be published next month.（这本书将在下个月出版。
）2. 隐藏执行者在某些情况下，句子中刻意隐藏了动作的执行者。
例如：- The cake was eaten.（蛋糕被吃了。
）3. 顺序执行之动作被动语态常用于描述一系列按照一定顺序执行的动作。
例如：- The eggs are washed, peeled, and then boiled.（鸡蛋洗净、剥皮，然后煮熟。
）4. 惯用表达被动语态在某些固定的表达方式中也得到了广泛使用。
例如：- The decision was made.（决定已经做出。
）- The question was answered.（问题已经回答。
）三、主动语态与被动语态的转换在主动语态与被动语态之间进行转换时，需注意以下几点：1. 意义的改变：动作的焦点转移到了接受者身上，原主语成为了新的宾语；2. 动词形式的变化：be动词的形式和动词的过去分词形式相关；3. 语态的时态保持一致：主动语态的时态与被动语态的时态保持一致。
中考初中英语被动语态讲解(精心整理)
中考初中英语被动语态讲解（精心整理）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。
英语有两种语态：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：时态被动结构一般现在时am/is/are+过去分词一般过去时was/were+过去分词一般将来时will/shall be+过去分词现在进行时am/is/are being+过去分词现在完成时have/has been+过去分词含情态动词can/may/must... be+过去分词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。

初中语法被动语态讲解
初中语法被动语态讲解被动语态定义: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 tostart.8) had been done 过去完成时例 By the end of last year, another new gymnasium had been completed inBeijing.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+(by …)否定句主语+be not+过去分词+(by …)一般疑问句 Be+主语+过去分词+(by …)?特殊疑问句疑问词+be+主语+过去分词+ (by …),3. 被动语态的特殊形式1) 带情态动词的被动结构。

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。

初中被动语态详细讲解
初中英语被动语态用法总结一、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。
现以动词clean为例列表说明：被动语态的句式变化：以一般现在时和动词invite为例，列表说明被动语态的句式变化：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。
初中英语被动语态知识点讲解
初中英语被动语态知识点讲解(名师总结中考必考知识点，建议下载背诵)一、定义语态用来表示主语和谓语之间的关系。
英语中有两种语态，一种是主动语态，表示主语是动作的执行者；另一种是被动语态，表示主语是动作的承受者。
例如：1. Kelly cleans the house every day. (该句为主动语态，主语Kelly是动作clean的执行者，宾语the house是动作clean的承受者。
)2.The house is cleaned by Kelly every day. (该句为被动语态，主语the house是动作clean的承受者，动作的执行者Kelly由介词by引出。
)二、用法当我们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，或者只需强调动作的承受者时，要用被动语态。
被动语态通常由“助动词be+及物动词的过去分词”构成, 如：English is spoken in many countries. Such books were written for middle school students. The computer should be turned off at once.三、句型: 被动语态的基本动词形式是be+V-pp。
通过改变be的时态，可以构成不同时态的被动语态。
(一)一般现在时的被动语态:be (am / is / are) +及物动词的过去分词（Unit 5）1.肯定陈述句：主语+am/is/are+V-pp+其他.e.g: The students are told to study hard.2.否定陈述句：主语+am/is/are+not +V-pp+其他.e.g:The students aren't told to study hard.3.一般疑问句：---Am/Is/Are+主语+V-pp+其他？—Are the students told to study hard?---Yes,主+am/is/are. No,主+ am/is/are +not. —Yes, they are. / No,they aren't.4.特殊疑问句：特殊疑问词+am/is/are+(主语)+V-pp+其他？e.g:Who are told to study hard?(二)一般过去时的被动语态：:be (was/were +及物动词的过去分词（Unit 6）1. 肯定句: 主语+ was/were + V-pp + (by…) .e.g: The news was published by the government.2. 否定句:主语+ was/were + not +V-pp + (by…) The news wasn’t published by the government.3. 一般疑问句: Was/Were +主语+ V-ed + (by…)?e.g: Was the news published by the government?4. 特殊疑问句: 疑问词+ was/were +主语+ V-ed + (by…)?e.g: When was the news published by the government?(三)含有情态动词的被动语态的结构为：情态动词+be +及物动词的过去分词。

Tony to take part in the talk show on CCTV-3 the day before yesterday.A. invitesB. invitedC. is invitedD. was invited【答案与解析】1. C。
由于句中主语是“Our classroom”，教室只能是被打扫，因此需要用被动语态来表达，再由句中“every day”确定，此处应该用一般现在时，其结构为is cleaned。
故选A。
2. B。
trees与plant存在着被动关系，应用动词的被动语态。
根据句意“为了我们的家乡更美丽，每年围着城市多种些树”。
故选B。
3. B。
由“in an hour”可知用将来时态，主语又是物，所以用将来时的被动语态。
4. B。
句意为“计算机被应用到每一地方”。
由句意可知用一般现在时的被动语态。
5. B。
由于主语是Hot water，可知用被动语态，由时间状语“from 5 pm to 7 pm now”可知用一般现在时的被动语态。
.6. A。
由句意“如果你的作业在五点钟前没有被完成，你就必须留下来”。
if引导的条件状语从句经常用一般现在时表示将来的意义。
且本句的主语是your homework，要用被动语态。
7. C。
由句意“我几乎没有（被给）时间准备考试，所以那时不自信。
”可知用一般过去时的被动语态。
8. D。
句意为“托尼前天被CCTY-3邀请参加了脱口秀”。
用一般过去时的被动语态。
【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：You are wanted on the phone. 有你的电话。
China was liberated in 1949. 1949年中国解放。
The problem will be discussed tomorrow.明天将对这个问题进行讨论。
Not a book in the library has been taken away.图书馆里没有一本书被人拿走。
My bike is being repaired.我的自行车正在修理。
The book had been borrowed when 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+ 其他被动语态: 间接宾语+ be + 过去分词+ 直接宾语+ 其他(比较常用)或:直接宾语+ be + 过去分词+ 介词(for / to) + 间接宾语+ 其他如：My father gave me a new book on my birthday.→ I was given a new book on my birthday (by my father).→ A new book was given to me on my birthd ay (by my father).我的父亲在我的生日那天给我买了一本新书。
My father bought me a new computer yesterday.→ I was bought a new computer yesterday (by my father).→ A new computer was bought for me yesterday (by my father).我的父亲昨天给我买了一台新电脑。
5.含有短语动词的主动语态变为被动语态有些相当于及物动词的短语动词,如“动词+介词”,“动词+副词”等,也可用于被动语态,但要把它们看作一个整体,不能分开。
如: She looks after her grandmother.→ Her grandmother is looked after (by her).她照顾她的祖母。
6.带有复合宾语的主动语态变为被动语态带有复合宾语(宾语+宾语补足语)的主动语态变为被动语态时,只把宾语变为被动语态的主语,原来的宾语补足语不动。
如：His teacher found him a very good pupil.→ He was found a very good pupil by his teacher.他的老师发现他是一个很好的学生。
7.变被动语态的其他注意点（1）在主动句中, let, make, see, hear等动词后作宾补的动词不定式不带to,但在被动句中,则要保留to。
如：Linda’s parents make her practice the piano every Sunday.→Lin da is made to practice the piano every Sunday.琳达的父母亲使她每天练习钢琴。
（2）有些及物动词如have(有),reach, cost等,以及有些连系动词如smell, taste, sound, feel等,不用于被动语态。
如：【误】Five dollars is cost by this book.【正】This book costs five dollars. 书花费了5元。
【误】The food is tasted nice.【正】The food tastes nice. 食物尝起来挺好。
（3）如move, lock, shut, open等作不及物动词与can’t, won’t等连用时,以及如read, write, wash, clean等作不及物动词与well, easily等副词连用时,已含有被动意义,因此形式上不再采用被动结构。
如：The door won’t open. 门不能开了。
The clothes wash well. 衣服洗好了。
