初中被动语态语法讲解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。

被动语态知识点讲解(更全面,思路清晰)
被动语态知识点讲解(更全面,思路清晰)被动语态知识点讲解被动语态是英语语法中的重要概念之一，它在句子中常常用来强调动作的接受者或者对象。
在本文中，我们将详细介绍被动语态的用法和结构，并提供一些实例用以帮助读者更好地理解和运用被动语态。
一、什么是被动语态被动语态是指句子的主语是动作的接受者或对象，而动作的执行者成为句子的宾语或介词短语。
被动语态使用助动词“be”加上动词的过去分词形式构成。
二、被动语态的结构根据被动语态的不同时态，其结构会有些许变化。
下面我们将一一介绍几种常见时态的被动语态结构：1. 一般现在时态：被动语态的一般现在时结构为：[be(am/is/are)] + [过去分词] + [by + 主语执行者]示例：1) 主动句：She writes a book.被动句：A book is written by her.2) 主动句：They make delicious cakes.被动句：Delicious cakes are made by them.2. 现在进行时态：被动语态的现在进行时结构为：[be(am/is/are)] + [being] + [过去分词] + [by + 主语执行者]示例：1) 主动句：He is washing the car.被动句：The car is being washed by him.2) 主动句：They are building a house.被动句：A house is being built by them.3. 一般过去时态：被动语态的一般过去时结构为：[be(was/were)] + [过去分词] + [by + 主语执行者]示例：1) 主动句：She bought a new car.被动句：A new car was bought by her.2) 主动句：They painted the wall.被动句：The wall was painted by them.4. 过去进行时态：被动语态的过去进行时结构为：[be(was/were)] + [being] + [过去分词] + [by + 主语执行者]示例：1) 主动句：He was cleaning the house.被动句：The house was being cleaned by him.2) 主动句：They were repairing the car.被动句：The car was being repaired by them.三、被动语态的用法被动语态的使用可以有多种情况，下面是几个常见的用法：1. 强调行为的接受者：被动语态可以强调动作的接受者或者对象，使其在句子中得到突出。
被动语态知识点讲解
被动语态语法专项讲解与训练(一) 语态分类：英语动词分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。
every day. (主动)The room(承) is cleaned(谓动) by Tom(执) every day. (被动)被动语态结构：助动词be + 动词的过去分词done，即be done ，常译为“被”、“给”、“由”、“受”等词用来表示被动关系。
(二) 被动语态的用法(1) 动作的执行者很明显。
这时往往不用by 短语。
Word processing skills are taught in our computer lessons.(2)不知道或没有必要说明动作的执行者是谁。
Some new computers were stolen last night.(3) 突出或强调动作的承受者。
如果需要说出动作的执行者，用by 短语。
The window was broken by Mike. 窗户是迈克打破的。
(三) 被动语态的时态变化：通过助动词be的各种时态变化来体现，done不变。
注意主语的单、复数变化。
以do为例，掌握下列时态的被动结构，形式变化如下：1．一般现在时：am / is / are + done2．一般过去时：was / were + done3．一般将来时：shall / will + be done am/is/are going to be done4．现在完成时：have / has + been + done5．情态动词：can/may/must/should/have to be done以下时态的被动语态作一般了解：现在进行时：am / is / are + being + done 过去进行时：was / were + being + done过去完成时：had + been + done 过去将来时：should / would + be done(四) 主动语态变被动语态的方法My aunt invited me to her dinner party.执行者动词承受者→I was invited (by my aunt ) to her dinner party.承受者谓语by+执行者1.把主动语态的宾语变成被动语态的主语。
语法中的被动语态详解
语法中的被动语态详解被动语态是英语语法中的一个重要部分，它能够有效地改变句子的结构，让句子更加灵活和准确。
被动语态可以表达动作的承受者而不是执行者，强调事件或行为对主语的影响。
本文将对被动语态进行详细的解释和讨论。
1. 被动语态的构成被动语态由“be”动词的不同形式加上主动语态的过去分词构成。
根据时态的不同，被动语态的构成也会有所变化。
下面是常见的被动语态构成方式：- 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：has/have been + 过去分词- 过去完成时：had been + 过去分词2. 被动语态的用法（1）强调动作的承受者被动语态常用于强调动作的承受者而非执行者。
通过使用被动语态，可以使主语不再是动作的执行者，而是动作的承受者。
例如：- 主动语态：They built the house.- 被动语态：The house was built by them.（2）省略执行人当我们不知道动作的执行者是谁，或者无需提及执行者时，被动语态也是一种很好的选择。
例如：- Active: Someone cleaned the room before the guests arrived.- Passive: The room was cleaned before the guests arrived.（3）强调动作本身有时候，我们希望强调动作或事件本身而不太关注执行者，这时使用被动语态是非常合适的。
例如：- Active: The dog bit John.- Passive: John was bitten by the dog.3. 被动语态的注意事项（1）及物动词和不及物动词的被动语态不同及物动词可以直接变成被动语态，但不及物动词需要加上适当的介词才能构成被动语态。
被动语态语法知识点总结
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——语法
被动语态英语被动语态的句子是以《be动词+过去分词》的形式来表达，如果要特别强调动作或行为的执行者时，句子后面需接by～，译为“被（由）……”。
1 被动语态的句型肯定句：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～）？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动词后面的过去分词不变。
一、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Our classroom is cleaned everyday.I am asked to study hard.Knives are used for cutting things.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.Dinosaur eggs were laid long long ago.3. 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.4. 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Uncle Wang is mending my bike now.→My bike is being repaired by Tom now.They are planting trees over there. →Trees are being planted over there by them.5. 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.6.过去进行时的被动语态构成：was/were + being + 及物动词的过去分词The boy was being operated on when his parents hurried to the hospital.The new road was being made.*过去将来时：should/would+及物动词的过去分词*过去将来完成时: should/would+have been +及物动词的过去分词7.过去完成时的被动语态构成：had + been + 及物动词的过去分词The classroom hadn’t been cleaned before the teacher came.The tickets had been sold out berore I came to the cinema.8.将来完成时的被动语态构成：shall/will + have doneThey will have been married for 20 years by then.The project will have been completed before May.9.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.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。
英语语法被动语态讲解
英语语法被动语态讲解英语语法被动语态讲解1.被动语态的构成由于不及物动词不能带宾语，故无被动语态，只有及物动词或相当于及物动词的动词短语才有被动语态，其基本构成方式是“助动词be+过去分词”。
注意：“be+过去分词”结构不一定都是被动语态，有些动词(如 be，feel，look，seem等)后面的过去分词已转化为形容词，用作表语表示状态。
如：My bike is broken.(我的自行车坏了。
)The door is open.(门开了。
)2.主动语态改被动语态的方法1)将主动语态改为被动语态应注意以下三个方面：①将主动语态的宾语改为被动语态的主语;②将主动语态的谓语动词改为“be+过去分词”结构;③将主动语态的主语改为介词by之后的宾语，放在谓语动词之后(有时可省略)。
2)含直接宾语和间接宾语的主动语态改为被动语态时有两种情况：①把间接宾语改为被动语态的主语，直接宾语仍保留原位;②把直接宾语改为主动语态的主语，此时，间接宾语前要加介词to或 for。
如：He gave the boy an apple.→ The boy was given an a pple.(或An apple was given to the boy.)Her father bought her a present.→ She was bought a present by her father.(或A present was bought for her by her father.)3)不带to的动词不定式作宾语补足语的主动语态，改为被动语态时不定式前要加to。
如：They watched the children sing that morning.→ Th e children were watched to sing that morning.4)带复合宾语的动词在改为被动语态时，一般把主动语态的宾语改为主语，宾语补足语在被动语态中作主语补足语。
被动语态的语法知识点分析
被动语态的语法知识点分析被动语态的语法学问点分析1(一)被动语态的`概念：不知道或没必要提到动作的执行者是谁时用被动语态。
强调或突出动作的承受者常用被动语态(by短语有时可以省略)。
(二)被动语态的构成方式：be + 过去分词，口语只也有用get / become + 过去分词表示。
(三)被动语态的基本用法：(1)使用被动语态时应留意的几个问题。
①主动改变被动时双宾语的改变。
看以下例句。
My friend gave me an interesting book on my birthday. An interesting book was given to me(by my friend)on my birthday.I was given an interesting book (by my friend)on my birthday.②主动变被动时，宾补成主补(位置不变);(作补语的)不定式前需加to。
The boss made him work all day long.He was made to work all day long(by the boss)③短语动词变被动语态时，勿要掉“尾巴”。
The children were taken good care of (by her).Your pronunciation and spelling should be paid attention to.④情态动词和be going to、be to、be sure to、used to、have to、had better等结构变被动语态，只需将它们后面的动词原形变为be +过去分词。
⑤当句子的谓语为say、believe、expect、think、know、write、consider、report等时，被动语态有两种形式：(A)谓语动词用被动语态，动词不定式作主补。
(B)用it作形式主语，真正的主语在后面，用主语从句来表示。
英语语法被动语态知识点梳理
英语语法被动语态知识点梳理在英语语法中，被动语态是一个重要且常用的语法点。
理解和掌握被动语态对于准确、流畅地表达意思以及提高英语语言能力都有着至关重要的作用。
下面咱们就来详细梳理一下被动语态的相关知识。
一、被动语态的构成被动语态的基本构成是“be ＋过去分词”。
其中，“be”动词要根据不同的时态和主语进行变化，过去分词则保持不变。
比如，一般现在时的被动语态是“am/is/are ＋过去分词”，一般过去时是“was/were ＋过去分词”，现在进行时是“am/is/are ＋ being ＋过去分词”，过去进行时是“was/were ＋ being ＋过去分词”，现在完成时是“have/has ＋ been ＋过去分词”，过去完成时是“had ＋ been ＋过去分词”等等。
举几个例子帮助大家理解：“ The book is written by him ”（一般现在时的被动语态）“ The tree was cut down yesterday ”（一般过去时的被动语态）“ The problem is being discussed now ”（现在进行时的被动语态）“ The work had been finished before he came ”（过去完成时的被动语态）二、被动语态的使用场景1、不知道或没必要指出动作的执行者当我们关注的是动作本身而不是执行者时，就会使用被动语态。
例如：“The window was broken ”（不知道是谁打破了窗户）2、强调动作的承受者为了突出动作的承受者，会使用被动语态。
比如：“This song is loved by many people ”（强调很多人喜欢这首歌，而不是强调谁让很多人喜欢这首歌）3、出于礼貌或委婉在某些情况下，使用被动语态可以使表达更委婉、更礼貌。
比如：“It is suggested that you should come earlier ”（用被动语态比直接说“ We suggest that you should come earlier ”更委婉）三、主动语态变被动语态的方法1、把主动语态中的宾语变成被动语态的主语。
英语语法被动语态讲解
被动语态一、被动语态在各种时态中的结构一般现在时：be done（be随人称变化）一般过去时：was/were done一般将来时：will be done现在进行时：be being done（前面的be随人称变化，后面的being固定）过去进行时：was/were being done（being固定）现在完成时：have/has been done过去完成时：had been done过去将来时：would be done将来完成时：will have been done将来进行时：will be being done（being固定）将来完成进行时：will have been being done现在完成进行时：have been being done过去将来完成时：would have been done过去完成进行时：had been being done过去将来进行时：would be being done过去将来完成进行时：would have been being done二、被动语态的基本用法：被动语态表示一种主语和谓语之间的关系，当主语是动作的承受者时，就需要用到被动语态，汉语中所说的，“汽车被撞坏了”“钢笔被修好了” 等句子就是一种被动语态的句子，在汉语中常用“被”“由”等词来表示这种被动语态。
在英语中则用动词的被动语态形式来表示。
被动语态中还可用by 短语加在句后表示被动语态中动作的发出者。
也就是谓语动词动作的逻辑上的主语，被动语态常用在下列情况。
1、不知道谁是谓语动词动作的执行者时，或者没有必要说出谁是执行者时。
The glass was broken last night. 玻璃昨天被打破了。
His bike has been stolen. 他的自行车被偷了。
He was asked to go there once more. 他被要求再去那儿一次。
2、为了强调或突出动作的承受者时。
英语语法：被动语态讲解
重点难点一、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二、非谓语动词的主动形式表被动意义在某些句型中可用动名词和不定式的主动形式表被动意义。
1．在need，want，require, bear等词的后面，动名词用主动形式表示被动意义，其含义相当于动词不定式的被动形式。
例The house needs repairing（to be repaired）．这房子需要修理。
2．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。
例The picture-book is well worth reading．（＝The picture-book is very worthy to be read．）3. 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。
高考语法被动语态
高考语法被动语态高考英语语法被动语态被动语态在英语中是一个重要的语法结构，也是高考中常考的一部分。
掌握被动语态的用法和构成规则对于提高写作和阅读理解的能力非常重要。
本文将为大家详细介绍高考英语语法被动语态的相关知识点，帮助大家更好地应对高考。
一、被动语态的构成规则被动语态由不及物动词和及物动词的宾语加上be动词的各种时态构成。
be动词的时态根据主语的时态来决定。
被动语态的构成公式为：be(各种时态)+过去分词。
1. 现在时态：am/is/are(被动语态) + 过去分词例如：The letter is written by Mary.（这封信是玛丽写的）2. 过去时态：was/were(被动语态) + 过去分词例如：The car was repaired by the mechanic.（这辆车是机修工修的）3. 现在完成时态：have/has(被动语态) + been + 过去分词例如：The book has been read by many people.（这本书已经被很多人读过了）4. 过去完成时态：had(被动语态) + been + 过去分词例如：The work had been finished when he arrived.（他到达时工作已经完成了）5. 将来时态：will be(被动语态) + 过去分词例如：The report will be presented tomorrow.（这份报告将于明天呈现）二、被动语态的用法被动语态主要用于以下几个方面：1. 强调行为的承受者例如：The concert was attended by thousands of people.（成千上万人参加了这场音乐会）2. 不知道或不提及行为的执行者例如：The bike was stolen last night.（这辆自行车昨晚被偷了）3. 对行为的执行者表示无关或不重要例如：The window was broken by accident.（窗户不小心被打破了）4. 当使用主动语态时没有行为的执行者例如：English is spoken all over the world.（英语在全世界使用）（注意：这个句法中没有明确的执行者，因为人们世界各地都在使用英语）三、被动语态的注意事项在使用被动语态时，我们需要注意以下几个问题：1. be动词的时态根据主语的情况来确定例如：The book is being read by students.（这本书正在被学生们读）2. 不及物动词无被动语态，无法构成被动语态的动词需要转换为及物动词或使用其他表达方式。
被动语态详解
被动语态详解一、被动语态的用法：1、不知道或没有必要指出谁是动作的执行者时。
The bridge was built last year.这座桥是去年建造的。
He was elected chairman.他被选为主席。
2、当更增强调动作的承受者时。
此时动作的执行者由by引导置于谓语动词之后，不需要时能够省略。
The room hasn't been cleaned yet.房间还没有清扫。
The tiger was killed by him.老虎被他杀死了。
3、当动作的执行者不是人时，多用被动语态。
如：The window was blown by wind.窗户被风吹开了。
The whole village has been washed away by the flood.整个村庄都被洪水冲走了。
4、表示客观的说明常用"It is + 过去分词."句型。
It is said that Lucy has gone abroad.据说露茜已经出国了。
It is believed that he is a spy. (=He is believed to be a spy.)大家相信他是个间谍。
其它常见的"It is + 过去分词+ that"句型还有It is reported that…据报道It is said that…据说It is believed that…大家相信It is suggested that…有人建议二、被动语态形式：被动语态的核心就是be + done,但be 根据时态有各种变化！1.一般现在时is/am/are +done2.一般过去时was/were +done3.一般将来时will be +done4. 过去将来时would be +done5.现在实行时is/am/are being +done6.过去实行时was/were being +done7.现在完成时has/have been +done8.过去完成时had been +done三、、各种时态的被动语态举例（以动词do为例）1．一般现在时（am/ is/ are +done）English by lots of people in the world. 世界上的很多人都说英语。
被动语态的语法解析
被动语态的语法解析一、被动语态的含义英语中时态很多，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：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：①Paper is made from wood.纸是由木材生产出来的。
②The house is quite old. It was built in 1950.这座房子太旧了。
它是1950年建成的。
③He was wounded in the fight.他在战斗在受伤了。
④Electricity 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：①Calculator can t be used in the maths exam.计算器不能用于数学考试。
②Books and newspapers in the reading room mustnt be taken away.阅览室的书籍和报纸不准带走。
③He 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。
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。
中考英语语法丨被动语态详解
中考英语语法丨被动语态详解被动语态是动词的一种特殊形式，表示句子中的主语是动作的承受者，也就是动作的对象。
一般说来，只有需要动作对象的及物动词才有被动语态。
被动语态的构成是：助动词be＋动词过去分词。
一、被动语态的用法1．不知道动作的执行者是谁或者说话的人对宾语的兴趣大于对主语的兴趣。
Printing was introduced into Europe from China.印刷是从中国传入欧洲的。
2．出于修辞的原因或者为了更好地安排句子。
The professor came to our school and was warmly welcomed by the teachers and students.那位教授来到我校并受到师生们的热烈欢迎。
3．不愿意说出动作的执行者，目的是为了使语言得体，在这种情况下，有时使用一些特别句式。
It is said that...据说……It is hoped that...大家希望……It is declared that...据宣布……It is well known that...众所周知……二、被动语态的几种类型1．含有单个宾语的被动结构It is often used (by my teacher) in teaching English.这经常(被老师)用于英语教学中。
2．含有双宾语的被动结构teach，tell，give等动词后面往往有两个宾语，叫作双宾。
带双宾语的主动句用被动句表示时，可以把其中一个宾语用作主语，另一个宾语作保留宾语。
但以指人的间接宾语作主语为好，句子显得更自然。
We gave them some books.我们给了他们一些书。
→They were given some books.→Some books were given to them.但也有的只能以直接宾语作为被动句的主语。
I will buy you a present.我将给你买份礼物。
被动语态知识点
被动语态知识点被动语态是英语语法中的一个重要知识点，它在表达句子时可以改变句子的重点和语态。
在被动语态中，主语是动作的接受者，而不是执行者。
本文将介绍被动语态的基本结构和用法，并通过一些例句来说明。
一、被动语态的基本结构被动语态由be动词（am、is、are、was、were等）与过去分词组成。
下面是被动语态的基本结构：【被动语态结构】主语 + be动词 + 过去分词 +（其他成分）被动语态可以用于各种时态，包括现在时、过去时、将来时等，只需将be动词与过去分词进行相应形式的变化。
二、被动语态的用法1. 表达对动作的强调被动语态可以突出动作的接受者，对动作的强调起到关键作用。
例如：Active: The dog bit the man.被动态: The man was bitten by the dog.这个例子中，主动语态中的重点是狗咬了人，而被动语态中的重点在于人被咬了。
2. 表达无法知道动作的执行者有时，我们并不关心动作的执行者，只关注动作的接受者或结果。
被动语态可以很好地满足这种需要。
例如：Active: They have built a new bridge.被动态: A new bridge has been built.这个例子中，被动语态中没有指明是谁建造了新的桥梁，只强调了新桥修建完成的事实。
3. 表示客观事实被动语态在表达客观事实或普遍真理时很常用。
例如：Water boils at 100 degrees Celsius.水在100摄氏度时会沸腾。
这个例子中，被动语态用于表达普遍真理，而不指明由谁主动进行沸腾。
4. 特殊动词的被动形式部分动词在被动形式中使用较高频率，如：give, lend, show, tell等。
例如：Active: He showed us the way.被动态: The way was shown to us.这个例子中，被动语态更好地突出了动作接受者。
被动语态语法知识
被动语态语法知识1．被动语态：1）被动语态的基本构成形式：主语+助动词be+动词的过去分词。
2)被动语态的时态：被动语态的时态是通过助动词be的变化体现。
这个助动词必须与主语的人称和数相一致。
现在以teach为例，将被动语态常用时态列表如主动语态：主语（动作发出者）→谓语（及物动词）→宾语（动作承受者）被动语态：主语（动作承受者）←谓语（be+动词过去分词）←宾语（动作发出者）He wrote the letter.→The letter was written by him.4）主动句变被动句的基本句式：a) 主：主语+助动词（情态动词）+谓语+宾语被：主语（原宾语）+助动词（情态动词）+be+动词过去分词+by+原主语如，We will help him.→He will be helped by us.a)主：主语+动词短语+宾语被：主语（原宾语）+be+动词短语的过去分词+by+原主语如，They looked after the babies.→The babies were looked after by them.b)主：主语+谓语+间接宾语+直接宾语被：主语（间接宾语）+be+动词过去分词+原直接宾语主语（直接宾语））+be+动词过去分词+to(for)+原间接宾语+（by+原主语）如，We gave him some magazines.→He was given some magazines.Some magazines were given to him by us.【注意】一般将主动句中表示人的间接宾语变为被动句中的主语。
c)主：主语+谓语+宾语+宾语补足语被：主语（原宾语）+be+过去分词+原宾语补足语如，They elected him their monitor.→He was elected their monitor.We told her to have a rest.→She was told to have a rest.We heard the baby crying.→Thy baby was heard crying.【注意】如果主动句中宾语补足语是不带to的不定式，变成被动语态后一般要加to.I saw him go to the church.→He was seen to go to the church.The boss made Tom work day and night.→Tom was made to work day and night. 【扩展】一般在以下几种情形时，需要使用被动语态。

初中英语被动语态详解●一、被动语态什么是被动语态？要弄懂什么是被动语态，让我们先了一下解语态。
什么叫语态？是动词的一种形式，用于表明主语与谓语之间的关系。
英语中时态很多，但语态只有两种，即：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。
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、被动语态的谓语结构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.English is spoken by people in the world.通过上面的例句，可以看出，被动语态的谓语结构是：“be + 及物动词的过去分词”●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。
例如：Paper is made from wood. (纸是由木材生产出来的。
)2.没有必要指出动作的执行者。
例如：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. (他在战斗中受伤了。
)Electricity is used to run machines. (电是用来开动机器的。
)3.只需要强调动作的对象时。
例如：The classroom is cleaned every day.Calculator can't be used in the math exam.(计算器不能用于数学考试。
)4.为了使语气婉转，避免提到是谁做的这件事。
例如：The new library must be completed by the end of next month. (新图书馆必须在下个月底前完工。
)一般地讲，被动语态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Our classroom is cleaned every day.This car is made in China.一般现在时被动语态的几种句型:1) 肯定句: 主语+am/is/are + V-ed + (by…)Our classroom is cleaned every day.2) 否定句: 主语+ am/is/are + not + V-ed + (by…)Our classroom is not cleaned every day.3) 一般疑问句: Am/Is/Are + 主语+ V-ed + (by…)?Is our classroom cleaned every day?4) 特殊疑问句: 疑问词+ am/is/are + 主语+ V-ed + (by…)?What time is our classroom cleaned every day?●2、一般过去式的被动语态E.g.His desk was cleaned just now.The building was built in 1928.一般过去时被动语态的几种句型:1) 肯定句: 主语+ was/were + V-ed + (by…)The news was published by the government.2) 否定句: 主语+ was/were + not + V-ed + (by…)The news wasn’t published by the government.3) 一般疑问句: Was/Were + 主语+ V-ed + (by…)?Was the news published by the government?4) 特殊疑问句: 疑问词+ was/were + 主语+ V-ed + (by…)?When was the news published by the government?●3、现在完成时的被动语态Some new building have been built in the city since last year.Your watch has been mended already.4、过去完成时的被动语态:had + been + 及物动词的过去分词如：He said that some new factories had been built in the city.I didn't know that my watch had been mended .●5、一般将来时的被动语态:①will/shall + be + 及物动词的过去分词② am/is/are + going to be +动词的过去分词.如：Some new building will be built in our city this year.Your watch is going to be mended in an hour.6、过去将来时的被动语态:(1).would / should + be + 及物动词的过去分词如：(2).was / were +going to be + 动词的过去分词.She said that some new factories would be built soon in our city.He thought that your watch was going to be mended after an hour.7.现在进行时的被动语态: am / is / are + being + 及物动词的过去分词如：A new factory is being built in our city now.Some trees are being cut down in the park.8、过去进行时的被动语态: was / were + being + 及物动词的过去分词如：A new factory was being built in our city at that time. Some babies were being looked after by Miss Chen last year.●9、含情态动词的被动式：情态动词 + be +及物动词的过去分词如：The key could not be found last night.The homework must be finished before dinner.五、如何将主动语态变成被动语态I.主动语态变被动语态：可简单记为主变（介词by的）宾，宾变主，谓语结构主动变被动图示：主动语态：主语+ 谓语(主动）+宾语+其他被动语态：主语+谓语(被动）+（by+宾语）+其他II.主动语态与被动语态互换巧记法：主动语态：人们说英语。
People speak English in many countries.English is spoken（by people) in many countries..被动语态：英语被说。
如何将主动语态变成被动语态,具体方法举例:1、从句子意义上说，就是重新找出“什么事物”是“被完成”的。
例1.主动语态：人们说英语。
People speak English in many countries. 被动语态：英语被说。
English is spoken in many countries.. 例2.主动语态：我们造这座桥。
We built this bridge last year.被动语态：这座桥被建造。
This bridge was built last year.2、从语法的角度说，把原句的宾语改成主语。
例1.主动语态：小王邀请你(宾语) Xiao Liu has invited you to a lunch party. 被动语态：你(宾语)被邀请。
You has been invited to a lunch party by Xiao Wang.例2.主动语态：你不准带走杂志(宾语) You must not take these magazines out of the reading-room.被动语态：杂志(宾语)不准被带走.These magazines must not be taken out of the reading room.例3.主动语态：他们授给他(宾语)一枚奖章(宾语).They gave him a medal for his wonderful work.被动语态：他(宾语)被授予一枚奖章. He was given a medal for his wonderful work.被动语态：一枚奖章(宾语)被授给了他.A medal was given to him for his wonderful work.※关于被动语态以下几点需要特别注意：1.被动语态中介词by及它的宾语可以省略，除非必须指出动作的执行者。
eg .In the end ,we all know the window was broken by Tom.※2.感官动词如see, hear , feel ,find, watch, notice等和使役动词如make, let，have等，在主动语态中要接省略to不定式作宾语补足语，在被动语态中些词后面的动词不定式都需要带to即：都要接to do不定式.eg. My mother often lets me take out the rubbish.(主动）I am often let to take out the rubbish by my mother.(被动）顺口溜：感官动词一感二听三让四看主动句中to 离开，被动句中to回来3.及物动词和动词+介词或动词+副词后可接宾语的动词短语才有被动语态。
eg. The meeting will be put off tomorrow.注意: “不及物动词+介词 / 副词”构成的短语动词，变成被动句时，要把它们作为整体看待，介词或副词不可与其动词拆开或漏掉。
如：Our homework was handed in yesterday afternoon.The house was fixed up by my father.4.带双宾语的动词，变被动语态时，可以把其中任意一个宾语变成主语，另一个留在被动结构谓语后面。
