被动语态
英语中有两种语态：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
一. 被动语态使用要点：
1. 不及物动词/不及物性短语动词不能用于被动语态
appear, die, happen, occur, belong to, break out, take place
2. 表示状态的动词不能用于被动语态
英语中有些动词/短语动词不是表示动作，而是表示某种状态或情况，有“拥有，容纳，适合，缺少，明白”等意。这类词不能用于被动语态。
lack, fit, mean, hold, have, cost, contain, suit, last, become, possess, benefit, fail, look like
二构成：
被动语态由助动词be+过去分词构成，时态通过be表现出来。
一般现在时：am／is／are＋p．p．
一般过去时：was／were＋p．p．
一般将来时：shall ／will be ＋p．p．
现在完成时：have ／has been ＋p．p．
现在进行时：am／is／are＋being＋p．p．
过去将来时：should ／would be ＋p．p．
含情态动词的被动结构：情态动词＋be＋p．p．
带不定式的被动结构：The homework needs to be done with care.
※将主动语态变被动语态应注意几个特殊情况：
一．含双宾语的主动结构变为被动结构时，有两种方法：
①将间接宾语变为主语，直接宾语保持不变；
②将直接宾语变为主语，间接宾语用介词to或for引导。例如：
He told us a story．（变被动语态）
→We were told a story（by him）．或：A story was told to us by him．
有时用间接宾语作主语讲不通，或不习惯，也须转用直接宾语作主语。如：
My girl friend writes me a letter every week．
I am written a letter by my girl friend every week．（错句）
A letter is written to me by my girl friend every week．
类似的动词有：return，send，pass，hand，sell，teach等。
二、短语动词的被动语态：在变为被动语态时，要将短语动词视为一个整体，其后的介词或副词不能省去。
1 动词＋介词：agree to, ask for, call for, laugh at, listen to, look after, operate on, send for, talk about, think of等。
a．The doctor has already been sent for．b．The news has never been heard of before．
类似的短语动词有：call on，look after，talk about，look at，ask for，wait for．．．
2．动词＋副词：bring about, carry out, find out, give up, hand in, make out, pass on, point out, put away, put off, take up, think over, turn down, turn out, wipe out, work out等。
a．A new play will be put on (上演) next week．b．The problem has been worked out．
3．动词＋副词＋介词：do away with, face up to, give in to, look down upon, make up for, put up with，类似的短语动词有：get out of，look out of，get on with，get along with (与。。。相处)，等。
a．The poor were looked down upon before liberation．解放前穷人被人瞧不起。
b．He was looked up to by everyone．他被人们所敬仰。
catch up with (赶上)，keep up with (跟上)．．．
4．动词＋名词＋介词类似的短语动词有：catch sight of, keep an eye on, make use of, make a fool of, pay attention to, put an end to, set fire /light to, take care of, take hold of, take notice of 等。
a．Lin Fen can take good care of your children．
1）Your children can be taken good care of by Lin Feng．
2）Good care can be taken of your children by Lin Feng．
b．They never paid attention to (注意、关注) the matter．
1）The matter was never paid attention to．2）Attention was never paid to the matter．
三。带复合宾语的动词在改为被动语态时，一般把主动结构中的宾语改成主语，宾语补足语保留在谓语后面。例如：
We always keep the classroom clean.
(比较：The classroom is always kept clean.)
四。有些动词形式上是主动结构，但表示被动的意思。
1。表示开始，结束类的动词。Start, open, begin, close, stop. End
The meeting ended at11 o’clock.
2。表示烹调，饮食方面的。The meat is cooking now.
3. 表示主语的特征和状态的(后需加adv. well/easily)。read, write, sell, clean, wash, wear, burn, lock等
The cloth washes well.这布很经洗。 The new product sells well.这新产品很畅销。
The pen writes well.这枝笔很好用
The girl does not photograph well.(强调女孩的特点，不上照。)
The girl has not been photographed well.（与女孩本人无关，在于摄影师没有照好。）
4。表示“需要”need/want/require doing = need/want/require to be done
5 be to blame/be to rent 主动表被动
6. be + adj. + 不定式此类形容词有easy/ hard/comfortable/dangerous/difficult/heavy/fit
7.感官动词和系动词+adj. feel/ look/smell/sound/taste/prove….
The water feels cold.
8. be worth + doing
6）下列情况主动句不能改成被动句：
①谓语是及物动词leave, enter, reach, suit, benefit, lack等。
②谓语是不可拆开的短语动词take place, lose heart, belong to, consist of等。
③宾语是反身代词，相互代词，同源宾语，不定式，动名词，抽象名词等。
7）汉语有一类句子不出现主语，在英语中一般可用被动结构表示。例如：
据说…… It is said that …希望… … It is hoped that …
据推测说… … It is supposed that …必须承认… … It must be admitted that …
必须指出… … It must be pointed out that … 众所周知… … It is well known that …
注意：这种结构可改为“Sb/Sth + be + pp + 动词不定式” 。例如：
It is said that Tom has got the first place in the exam.=Tom is said to have got the first place in
the place.
It was reported that her mother died of SARS.=Her mother was reported to have died of SARS.※被动语态和过去分词作表语的区别：
含义不同：被动语态强调动作，重点说明动作由谁完成、怎样完成；而过去分词作表语通常用来描写情景，叙述人或事物的特征及所处的状态。试比较：The window is broken．窗子破了。（系表结构）
The window is broken by him．窗子被他打破了。（被动语态）
主动语态变被动语态的几个特例 一、含有双宾语的句子变为被动语态时，多数将主动句中的间接宾语变为被动句的主语，直接宾语作保留宾语；也可将直接宾语变为主语，间接宾语作保留宾语，但这时保留宾语前多加介词to或for。如：He gave me a new watch.→1) I was given a new watch. 2) A new watch was given to me. 二、含有复合宾语且宾语补足语是名词的句子变为被动语态时，只能将主动句中的宾语变为被动句中的主语，宾补不可变为主语。如：They call me Jim. →I am called Jim.(不可说：Jim is called me.) 三、主语为疑问词的疑问句变为被动语态时，用“By+疑问词（宾格）”置于句首。如： Who broke the glass? →By whom was the glass broken? 四、祈使句变为被动语态时，要改为“Let +原宾语+be+过去分词”。如：Close the window. →Let the window be closed. 五、带宾语从句的复合句变为被动语态时，多用it作形式主语置于句首，原宾语从句成为真正主语（从句），从句中也需用被动语态。如：People said that Lin Feng could take good care of the baby. → It was said that the baby could be taken good care of by Lin Feng. 六、含有谓语动词know的主动句变为被动语态时，不用by短语，需by改为to。如： We all know the scientist. →The scientist is known to us all. 七、no one、nobody等否定代词作主语的句子变为被动语态时，谓语

语态是表示主语和动词之间的主动关系或被动关系的动词形式。英语动词有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者（施动者），被动语态表示主语是动作的承受者（受动者）。本单元的语法是一般将来时态的被动语态，现就其用法归纳如下： 一、一般将来时态的被动语态的基本结构的构成： 1．一般将来时态的被动语态的肯定式为：主语+shall / will + be done。(shall 用于第一人称，will用于各种人称) 如：We shall / will be punished if we break the rule. 如果我们违反规定，我们将要受到惩罚。 The new film will be shown next Thursday. 这部新电影将在下周四上映。 2．一般将来时态的被动语态的否定式为：主语+shall / will + not + be done.（可缩写成shan’t或won’t）如： The meeting won’t be held tomo rrow. 明天不再举行会议。 The exhibition won’t be put off till next week.
展览会将不会推迟到下周。 3．一般将来时态的被动语态的一般疑问句句式：shall / will+主语+be done。（回答用yes或no）如： Won’t water be turned into ice, i f it is below freezing temperature? 如果气温在冰点之下，水难道不会变成冰吗？ ---Will the work be finished at once? ---Yes, it will. ---这项工作会立刻被完成吗？---是的，立刻就完成。 4．一般将来时态的被动语态的特殊疑问句为：疑问词+ shall / will + 主语+ be done。如： When will these books be published? 这些书将在什么时候被出版？ 二、一般将来时态的被动语态的其他结构构成： 1．主语+be going to +be done Some old buildings are going to be put down. 一些旧的楼房将被推倒。 The problem isn’t going to be discussed at the meeting tomorrow.
动词的主动语态和被动语态【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：Youare wantedon the phone.有你的电话。 Chinawas liberatedin 1949. 1949年中国解放。 The problemwill be discussedtomorrow. 明天将对这个问题进行讨论。 Not a book in the libraryhas been taken away. 图书馆里没有一本书被人拿走。 My bikeis being repaired.我的自行车正在修理。
The bookhad been borrowedwhen 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 动词语态（Voice）是表示动词主语与动词所表示的动作之间关系的?种动词形式。动词语态有两种：主动语态（T he Act ive Voice）和被动语态（T he Passive Voice）。主动语态表示主语是动作的执?者。被动语态表示主语是动作的承受者。动词被动语态由“be＋过去分词”构成。 ? 能?于被动语态的动词特征 1．只有及物动词才能?于被动语态。例如： T he poem was writ t en by him. 这?诗是他写的。 A new element has been discovered by t he scient ist. ?个新元素已被这位科学家发现。2．注意某些及物动词语态的正确使? （1）表示情感的动词 excit e 使…激动，int erest 使…产?兴趣，sat isfy 使…满意，delight 使…?兴，please 使…?兴，ast onish使…惊奇，puzzle 使…困惑，confuse 使…糊涂，embarrass 使…尴尬，annoy 使…不悦，amaze 使…惊异，等。 例如： T he news excit ed us. 消息使我们激动。 We were excit ed at t he news. 听到消息我们很激动。 T he int erview sat is?ed t he manager. 访谈使经理满意。 T he manager was sat is?ed wit h t he int erview. 经理对访谈很满意。 （2）表示受伤的动词hurt, injure, wound。例如： T he driver hurt himself in t he accident. T he driver was hurt in t he accident. 驾驶员在事故中受伤。 T he bullet wounded his back. He was wounded in t he back. 他背部被?弹打伤。 （3）其他动词如base 以…为基础，line 沿…排列，?ll 使…充满，separat e 使…分离，crowd 塞满，cover 覆盖，等。例如： He based his ?lm on a t rue st ory. His ?lm was based on a t rue st ory. 他的影?以?个真实故事为基础。 Green t rees line t he highway. T he highway is lined wit h green t rees. 绿树沿公路排列。 She covered t he ?oor wit h a red carpet. T he ?oor was covered wit h a red carpet. 地板上铺着红地毯。 T he st rait separat es t he island from t he mainland. T he island is separat ed from t he mainland by t he st rait. 海峡把岛和?陆隔开。 ? 不能?于被动语态的动词特征 1．不及物动词不能?作被动语态
主动语态变被动语态的几种类型 一、含双宾语的主动结构变为被动结构 有些动词，如give，tell，buy等，在句中作谓语时可有两个宾语，又称双宾语，即“间接宾语+直接宾语”结构形式。含双宾语的主动结构变为被动结构时，可以将其中一个宾语变为主语，另一个保留不动。一般是主动结构的间接宾语变为被动结构的主语。如果直接宾语变为被动结构的主语，间接宾语之前应加介词to（可省去）或for（一般不可省）。如： 1 . My mother gave me a pen.~I was given a pen by my mother.或：A pen was given (to) me by my mother.（介词to 可省略） 2 .He told her a long story.~She was told a long story.或：A long story was told (to) her.（介词to可省略） 3.Father bought me a new coat.~I was bought a new coat.或：A new coat was bought for me.（介词for不可省略）注意：被动句中强调间接宾语时，其前的介词to 不可省去。如： This apple is given to me, not to you.这个苹果是给我的，而不是给你的。 二、含复合宾语的主动结构变为被动结构 复合宾语指的是“宾语+宾语补足语（简称宾补）”这一结构形式。含复合宾语的主动结构变为被动结构时，只将主动结构中的宾
语变为被动结构的主语，宾语补足语保留不动。可充当宾语补足语的有名词、动词不定式、现在分词、过去分词、形容词、介词短语等等。如： 1.They call her Xiao Li.(主动结构，宾补为名词Xiao Li )~She is called Xiao LI.(被动结构) 2.They chose Tom monitor.（主动结构，宾补为名词monitor）~Tom was chosen monitor.（被动结构） 3.He told me to wait for you.（主动结构，宾补为不定式短语to wait for you）~I was told to wait for you.（被动语态） 4.I found him lying on the floor.（主动结构，宾补为现在分词短语lying on the floor)~He was found lying on the floor.（被动结构） 注意：在主动语态的句子中，谓语动词make的宾语补足语如果由动词不定式充当，则该动词不定式不带to。感官动词see，hear，watch等，也有这种用法。但当谓语动词是let时，其被动结构后的不定式仍不带to。例如： They made him go.（主动结构，宾补为不带to的不定式go)~He was made to go.（被动语态） They let John go.（主动结构）~John was let go.（被动结构） 三、含情态动词的主动结构变为被动结构
教学过程 被动语态的结构及用法 Step 1 Warm-up: Review 复习 一、Review the past participle forms of the verbs 1、规则动词过去分词的构成： (1)一般情况+ed 如worked；以不发音的e结尾，直接+d 如liked (2)以“辅音字母+y”，y →i+ed 如study →studied (3)以重读闭音节结尾，词尾仅一个辅音字母，双写词尾辅音字母+ed 如stopped，planned 2、特殊变化：课本附录 Step 2 Presentation:呈现 一、语态概述：略讲 1、英语的语态是通过动词形式的变化表现出来的，分为主动语态与被动语态两种。 2、主动语态，即主语是动作的执行者。Eg. We clean the classroom. 3、被动语态，即主语是动作的承受者。Eg. The classroom is cleaned by us. 二、被动语态的构成：略 被动语态的基本构成是“助动词be+及物动词的过去分词+(by)”。be本身无词义，但有时态、人称和数的变化。by通常紧跟在被动句谓语动词之后，有时也可省。 1、现在： （1）一般现在时am/is/are + done （2）现在进行时am/is/are + being done （3）现在完成时have/has + been done 2、过去： （1）一般过去时was/were + done （2）过去进行时was/were + being done 3、将来：一般将来时shall/will + be done 三、被动语态句式：略 （1）肯定：主语+be+过去分词+(by) The cars are made by them. （2）否定：主语+be+not+过去分词+(by)The cars are not made by them. （3）一般疑问句：Be+主语+过去分词+(by) Are the cars made by them? （4）含有情态动词的被动语态：主语+情态动词+(not)+be<原形>+过去分词+(by) 四、被动语态的用法： 1、强调动作的承受者eg. Her bike is stolen. 2、淡化动作的执行者（没有说明、没必要指出、不知道） Eg. This coat is made of cotton.这件大衣是棉制的。 3、动作的承受者是谈话的中心eg. The picture was drawn by a boy under eight. Step 3 Consolidation:巩固 五、主动与被动的转换：时态不变 A.主动中的宾语→被动语态的主语 B.谓语变成被动结构（be＋过去分词） C.主动中的主语→被动语态的宾语（介词by之后），主格→宾格 Eg. He cut down a tree.→A tree was cut down by him. 1、S+V+O
