中考被动语态复习一.动词被动语态基本概念和形式详解一、动词被动语态使用1、表示主语是动作的承受者The classroom was cleaned by the students this morning.The book was written by a middle school teacher.The lost bicycle was found by a farmer by the river.2、侧重说明主语接受动作,无须或无法知道动作的执行者Letters are collected from this mail-box at 7:30 a.m.Air pollution has been reduced in our city.The ground was covered with snow.二、动词被动语态形式1、动词被动语态由be+ 及物动词的过去分词构成。
动词被动语态的时态由助动词be 的各个时态变化形式表示;2、含情态动词的动词被动语态结构为“情态动词+be+过去分词”。
注意1:1、把原来的宾语提到前面作被动语态的主语;2、把动词变成“be + 过去分词”;3、可以主动语态中的主语变为介词by的宾语。
注意2:“主语+谓语动词+直接宾语+间接宾语”结构的被动语态:这类结构转换时,可以将间接宾语转换为主语;也可以将直接宾语转换成主语。
He showed us some of his photos.→We were shown some of his photos.Amy gave him a toy gun.→He was given a toy gun by Amy.I paid the taxi driver some money.→Some money was paid to the taxi driver.She bought me a new skirt.→A new skirt was bought for me.但有时根据句意往往将直接宾语转换成主语:The sentence was explained to us again.三、被动语态的否定句、疑问句The sentence was explained to us again.→Was the sentence explained to us again?→What was explained to us again?小练习将下列句子改为被动语态将被动语态句子改为否定句并有对下划线部分的句子进行提问,改成特殊疑问句1. A car knocked him down yesterday.2. Two doctors and ten nurses make up the medical team.3. When I got there, they were cutting up a fallen tree.4. We’ll put on the play next Sunday.5. Workers are building a new teaching building in our school.6. They had completed the railway by the end of last year.7. We should protect the earth.8. You need to paint the wall.9. Lucy gave Jack a pencil as a present.10. Our teacher showed a picture of Shanghai to us in the class.将下列句子改成被动语态1 His mother told him not to waste time on fishing.2 Father gave me a toy at Christmas.3 This factory produces machine tools.4 They should do it at once.5 They named the child Tom二.动词被动语态的特殊用法和相关句型一、不能用于动词被动语态的几种情况1、不及物动词不能用于被动语态The car doesn’t belong to me.The accident happened yesterday morning.2、连系动词不能用于被动语态The fruit tasted nice.His face turned red.3、某些短语动词作不及物动词也不能用于被动语态Great changes took place that year.二、动词被动语态转换时须注意的几个问题1、双宾语句子结构的转换(见3.1)2、“主语+谓语动词+宾语+(疑问词)+to do”句子结构的转换The man taught me how to repair a fridge.→I was taught how to repair a fridge.We asked her to sing a song.→She was asked to sing a song.3、带有“动词词组+宾语”句子结构的转换This old man is well looked after by the young man.These desks and chairs must be taken good care of.The notice was put up this morning.4、see, watch, hear, notice, feel, make, listen to, look at等动词/短语后作宾语补语的不定式都不带to;但改成被动语态后必须带to。
【被动语态】(一)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。
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. 主语English是动词speak的承受者。
(二)被动语态的构成人称、数和时态的变化是通过be的变化表现出来的。
一般现在时:am/is/are+V-过分一般过去时:was/were+V-过分一般将来时:will/shall be+V-过分过去将来时:would be + V-过分现在进行时:am/is/are being+V-过分过去进行时:was/were being+V-过分现在完成时:have/has been+V-过分过去完成时:had been + V-过分(三)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。
可省略。
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.一般现在时:I plant a tree every year. →I planted a tree last year. →I will plant a tree next year. →I would plant a tree the next year. →I’m planting a tree now. →I was planting a tree yesterday afternoon.I have planted many trees in the past few years. →I had planted many trees when I was 15. →练习:1. People play football all over the world2. They bought ten computers last term.3. They will finish the work in ten days.4. We are going to learn the words.5. We have made more than twenty toys.6. Some workers are painting the room.(四)含有情态动词的被动语态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.You must finish your homework today. →(五)特殊情况当使役动词have, make, get, let以及感官动词see, watch, notice, hear, feel, observe等后面的不定式作宾语补足语时,在主动结构中不定式to要省略,但变为被动结构时,要加to。
被动语态复习讲义一、主动变为被动的几个特殊情况:1.使役动词make/let sb do sth和感官动词see(hear, watch, feel) sb do sth结构变成被动句,要把省略的to加上。
如:They watched the children sing that morning.The children were watched to sing that morning.2. 带双宾语的动词结构如give( show, explain, bring, leave, buy) sb sth, 若将直接宾语sth变成被动语态的主语,间接宾语sb前要加to或for等。
如:Someone gave the boy an apple.An apple was given to the boy.、His father left him this house.This house was left to him by his father.Someone has bought him a present.A present has been bought for him.3.带有宾补的句子变被动时,只把宾语变成被动语态的主语就行了。
(下列划线部分是宾补,变成被动语态后,它们就成了主补)We call him Xiao Wang.He is called Xiao Wang.He cut his hair short.,His hair was cut short.He was told to help me.4.*当know, say, believe, find, think, report等词带有宾从时,要变被动通常用it作为形式主语,宾从不变。
也可采用另一形式。
People believe that he is ill.It is believed that he is ill.Or : He is believed to be ill.二、不能进行转化的情况:1.…2.只有主动无被动的情况:1)虽为及物动词,但其宾语并非动作的承受者。
GRAMMAR被动语态(一)被动语态常与时态、主谓一致等一起考查。
我们先通过下面的表格来复习一下不同时态的被动语态的构成形式。
下面我们以高考题为例,对被动语态的用法作个总结和延伸。
考点一:在时态中的应用【考例回顾】1. In the last few years thousands of films ______ all over the world. (天津2011)A. have producedB. have been producedC. are producingD. are being produced2. Experiments of this kind ______ in both the U.S. and Europe well before the Second World War. (北京2011)A. have conductedB. have been conductedC. had conductedD. had been conducted【点拨】1. 答案为B。
时间状语In the last few years常与现在完成时连用;films与produce 之间是被动关系,故用现在完成时的被动语态。
2. 答案为D。
根据句意,此动作是在二战之前发生,故用过去完成时;experiments 与conduct之间是被动关系,故用过去完成时的被动语态。
考点二:在动词不定式中的应用【考例回顾】1. If they win the final tonight, the team are going to tour around the city ______ by their enthusiastic supporters. (浙江2011)A. being cheeredB. be cheeredC. to be cheeredD. were cheered2.

被动语态复习资料被动语态复习资料在英语学习中,被动语态是一个重要的语法知识点。
它在句子中的使用非常广泛,能够帮助我们更准确地表达和理解信息。
本文将为大家提供一些被动语态的复习资料,帮助大家更好地掌握和运用这个语法结构。
一、被动语态的构成方式被动语态是由助动词“be”加上动词的过去分词构成的。
被动语态的形式如下:一般现在时:am/is/are + 过去分词例如:The book is written by John.(这本书是约翰写的。
)一般过去时:was/were + 过去分词例如:The car was repaired by the mechanic.(这辆车是修理工修好的。
)一般将来时:will be + 过去分词例如:The project will be completed by next month.(这个项目将在下个月完成。
)现在进行时:am/is/are being + 过去分词例如:The house is being painted by the workers.(这栋房子正在被工人们粉刷。
)过去进行时:was/were being + 过去分词例如:The cake was being baked when I arrived.(我到达时蛋糕正在被烘焙。
)二、被动语态的用法1. 强调动作的承受者被动语态可以强调动作的承受者,而不是动作的执行者。
这在一些情况下非常有用,例如在科学实验报告中,我们通常关注实验结果而不是实验者。
例如:The experiment was conducted by a group of scientists.(这个实验是由一组科学家进行的。
)2. 不知道或不关心动作的执行者有时候我们并不知道或并不关心动作的执行者,这时候使用被动语态可以更加准确地表达。
例如:The purse was stolen.(钱包被偷了。
)3. 避免重复使用主语当我们在连续的句子中多次提到同一个主语时,为了避免重复使用主语,可以使用被动语态。
被动语态复习“三步曲”被动语态是动词语态的一种形式,表示主语是动作的承受者。
在历年的中考题中,都有一定数量的考查被动语态的题目。
因此,有必要对被动语态进行系统复习。
第一曲:掌握被动语态的结构被动语态由"助动词+及物动词的过去分词"构成。
不同时态的被动语态的差异主要体现在助动词be的变化上,同时助动词be还要在人称和数上与主语保持一致。
现将初中阶段常见的几种时态的被动语态总结如下:1.一般现在时的被动语态:am/is/are+done(指及物动词的过去分词,下同)如:English is used all over the world.2.一般过去时的被动语态:was/were+done如: The picture was painted two years ago.3.现在进行时的被动语态:am/is/are+being+done如: The flowers are being watered by them now.4.现在完成时的被动语态:have(has)+been+done如:The room has been cleaned.5.一般将来时的被动语态:will/be going to+be+done如:The work will be finished tomorrow.6.含有情态动词的被动语态:情态动词+be+done如:Your homework must be handed in today.其它几种特殊句型:It is said that …….. It is well known that ……. It is reported that……..have sth done第二曲:掌握主动语态变被动语态的方法把主动语态变为被动语态时,应走好以下三步:1)主动语态的宾语变为被动语态的主语; 2)主动语态的谓语动词由主动语态形式变为被动语态形式; 3)主动结构的主语变为介词by的宾语,组成介词短语,放在被动结构的谓语动词之后。
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。
