语态(VOICE)语态也是动词的一种形式，表示主语与谓语之间的关系。

英语有两种语态：主动语态(Active V oice)和被动语态（Passive V oice）。

主动语态表示主语是谓语动作的执行者；被动语态表示主语是谓语动作的承受者。

如：The people supported him. He was supported by the people.一、被动语态的形式(Forms of Passive Voice)被动语态由助动词be+过去分词构成。

助动词be随着主语的人称、数、时态和语气的不同而变化。

[注] 被动语态与不同时态结合的变化形式一概表现在助动词be上。

一般现在时：English is widely spoken all over the world.一般过去时：The bridge was built in 1973.一般将来时：The baby will be taken to hospital soon.过去将来时：He said he would be criticized for what he did.现在完成时：The book has been translated into many languages.过去完成时：By 1960, 100 schools had been set up.现在进行时：The building is being built.过去进行时：When I went to the city, a high building was being built.将来完成时：This class will have been taught by Mr. Brown for two years by next summer.过去将来完成时：The headmaster said the article would have been translated by six o’clock.[注] 一般说来，及物动词可用于被动语态，因为及物动词有宾语，把宾语变成主语，句子即可改为被动结构。

一、谓语动词用主动表被动的五种情形(1) 某些连系动词(如look, sound, smell, feel, taste, prove等)要用主动表被动，因为连系动词为不及物动词，它们没有被动语态形式：That dog looks dangerous. 那只狗看起来很危险。

Your idea sounds a good one. 你的想法听起来很好。

My advice proved to be wrong. 我的意见证实是错的。

(2) 当open, close, shut, lock, move等用作不及物动词且表示主语的某种属性时，通常用主动形式表示被动意义：The door won't shut. 这门关不上。

The supermarket doors shut automatically. 超市的门是自动关的。

【注】该用法的不及物动词通常与can't, won't 等连用，注意它与用被动语态含义不同：The window won't shut. 这窗户关不上。

(说明主语的属性——窗户有问题了)The window won't be shut. 这窗户将不用关上。

(窗户本身没问题，只是不用关)有时可能用主动和被动形式均可，只是强调重点稍有不同：Suddenly the door opened. 突然门开了。

(不强调动作执行者)The door was suddenly opened. 门突然被打开了。

(强调动作执行者)(3) 当read, wash, clean, cook, cut, wear, carry等用作不及物动词且表示主语的某种属性时，通常要用主动形式表示被动意义：The cloth washes well. 这种布料好洗。

The book sells quickly. 这书销售得快。

This cheese doesn't cut easily. It's too soft. 这乳酪不容易切，太软了。

被动语态(完整版)一、单项选择被动语态1．The classroom ________ by students every day.A．cleans B．cleanedC．is cleaned D．is cleaning【答案】C【解析】【详解】考查时态和被动语态。

句意：教室每天都由学生打扫。

句子主语The classroom，单数第三人称形式，与谓语动词clean之间是被动关系，再结合every day，可知句子用一般现在时态的被动语态，故选C。

2．At the awarding ceremony held in Tokyo, the scientists were surprised by what ______ in science and technology.A．has discovered B．has been discoveredC．had discovered D．had been discovered【答案】D【解析】句意：在东京举行的颁奖仪式上，科学家们惊讶于科学技术的发现。

科学家们感到惊讶是过去式，故科学技术发现用过去完成时，what于动词discover是被动关系，故选D。

3．—Will Uncle Peterson come to my birthday party tomorrow?—Pity he ______ to Zimbabwe as a volunteer teacher.A．was sent B．has been sentC．had been sent D．would be sent【答案】B【解析】考查时态和语态。

句意：——Peterson叔叔明天会来参加我的生日聚会吗？——很可惜他已经被派到Zimbabwe去做志愿教师了。

由语境可知，Uncle Peterson被派到Zimbabwe这是发生在过去的事情，这个动作对现在产生了影响，故该空应用现在完成时态。

非谓语动词之动词不定式被动语态形一、复习各种时态的被动语态★被动语态的基本结构： be+ done（以 the book ， publish 为例）一般现在/过去时:The book is/ was published。

一般/过去将来时：The book will/would be published.The book is/was going to be published.现在/过去进行时：The book is/was being published.现在/过去完成时:The book has/had been published.情态动词：The book can/could/may/might…be published。

二、不定式的被动式的基础知识：2）完成式：（not/ never） to have been done （表示不定式动作发生在谓语动词之前）三、▲通常在believe， suppose, say， report等动词构成的句子中可以进行主动语态到被动语态以及被动语态和动词不定式的转换.如：They say that Mike is sick in bed.=It is said that Mike is sick in bed.=Mike is said to be sick in bed.据说麦克卧床不起。

People believe that he was killed.=It is believed that he was killed.=He is believed to have been killed。

大家相信他被杀了.四、当不定式的逻辑主语是不定式所表示的动作的承受者而非发出者时，不定式一般要采用被动形式（to be done）.语法功能：1．作主语:It is an honour for me to be asked to speak here.2．作宾语：She asked to be sent to work in Xinjiang。

Special passive voice forms:1.When a sense verb (XXX) or a causative verb(make/let/have) is followed by an infinitive without "to" in an active sentence。

the "to" should be added in a passive sentence。

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。

以give 为例，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 lab without a teacher. We are not allowed to enter lab without a teacher.2. 一般过去时：(1)They agreed on building a new car factory last month. a new car building factory was agreed on last month.(2)The students didn't forget his lessons easily. His lessons w ere not easily forgotten3. 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.5. 现在进行时：(1)The radio is broadcasting English lessons. English lessons a re being broadcasted on the radio.(2) We are painting the rooms. The rooms are being painted.6. 过去进行时：(1)The workers were mending the road. The road was being mended.(2)This time last year we were planting trees here. Trees were being planted here this time last year.7. 现在完成时：(1)Someone has told me the meeting might be put off.I have been told the meeting might be put off.(2)He has brought his book here. His book has been brought here.(四）含有情态动词的被动语态：含有情态动词的被动语态是由“情态动词+ be+及物动词的过去分词”构成。

被动语态用法详解TENSE 主动语态被动语态am\is\are+V(p. 一般现在时be+V.\V.sp)一般将来时will'be going to\be (about)to+V. will be +V(p.p)am\is\are+bein 现在进行时am\is\are+V.ingg+V(p.p)was\were+V(p. 一般过去时①was\were ② V.edp)have\has+bee 现在完成时have\has+V.p.pn+V(p.p)had+been+V(p 过去完成时had+V.p.p.p)was\were+bein 过去进行时was\were+V.ingg+V(p.p)情态动词情态动词情态动词+V.+be+V(p.p)被动语态牢记一点，be加动词过去分词。

分析句中主和谓，承受者作主语即被动。

短语动词不可忘介、副词。

另有不及物动词，只有主动无被动。

还要注意其时态，与主动语态全相同。

不用被动语态的情况1）不及物动词或动词短语无被动语态（即多数的瞬间动词）：appear, die （死亡）,disappea（（消失），end （vi. 结束），fail, happen, last, lie, remain, sit, spread, stand break out, come true, fall asleep, keep silenee, lose heart, take place. After the fire, very littleremained of my house. 比较：rise, fall, happen 是不及物动词；raise, seat是及物动词。

（错）The price has been risen.（对）The price has risen.（错）The accident was happened last week.（对）The accident happened last week.（错）The price has raised.（对）The price has been raised.（错）Please seat.（对）Please be seated.要想正确地使用被动语态，就须注意哪些动词是及物的，哪些是不及物的。

初中英语被动语态总结A．熟记结构被动语态的结构为“助动词be＋及物动词的过去分词（p．p）”。

被动语态的不同时态是通过be 的时态变化来表示的，其人称和数方面应与主语保持一致。

其具体变化为：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．例如：① Chinese ______ by the largest number of people．A．speak B．is speaking C．speaks D．is spoken② The boy ______ to get supper ready after school．A．were told B．is telling C．was told D．tells③ A lot of new roads ______ built in the west of China．A．must B．must be C．has D．haveB．明确用法被动语态常用于以下两种情况：1．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；2．强调动作的承受者。

例如：这棵树是那个男孩弄断的。

The tree ______ ______ by that boy．C．熟练转换1．将主动语态变被动语态的基本方法为：①将主动语态的宾语作被动语态的主语；②谓语动词变为“be＋及物动词的过去分词”，并通过be的变化来表达出不同的时态；③主动语态的主语变为介词by的宾语，组成介词短语放在被动结构中的谓语动词之后。

（有时by短语可以省略）。

2．被动语态的一般疑问句是将一个助动词置于主语之前；否定句是在第一个助动词后加not；特殊疑问句的语序为：疑问词＋一般疑问句。

【精品】被动语态详解+例句一、单项选择被动语态1． in a red dress, she was easy to in the big crowd at the airport.A．Being dressed; pick out B．Dressed; pick outC．Dressed; be picked out D．Having dressed; pick out【答案】B【解析】【详解】考查过去分词和动词短语。

句意：因为她穿着红色的裙子，所以在机场的人群中很容易被认出来。

be dressed in穿着……，作状语表状态，故用dressed。

sb be easy to do sth主动形式表达被动意思，所以用pick out。

故B选项正确。

【点睛】主动形式表被动意义的不定式1.主语＋be +adj. +to do。

能用于此句型的形容词有: difficult, easy, comfortable, fit, hard, pleasant, tiresome(使人疲劳的), interesting, nice, heavy, dangerous, light, important, etc.注意：当上述形容词在句中作宾语补足语，后接不定式时，不定式也用主动形式表达被动含义。

2.主语+be +adj. + enough +to do。

3.主语+be +too +adj. +to do。

4.不定式短语作后置定语时，如果主语是不定式动词短语的逻辑主语。

则采用不定式的主动形式表被动概念。

I have a meeting to attend today.5.There be 句型中，用来修饰主语的不定式多用主动。

6.在“疑问代词 + 不定式”结构中。

7.let, to blame, to seek等用不定主动形式表示被动含义。

8. with+O.+to do 结构中，不定式作宾补时，常用主动表被动，且表将要发生的动作。

3．It is the third time so far that such a festival ________ in my hometown.A．is held B．has been heldC．will be held D．had been held【答案】B【解析】试题分析：考查句式用法。

This is the first (second, third…) time +that从句，这是第一（二，三…）次…。

一般来说，This is the first (second, third…) time +that从句，这个句式中that从句使用现在完成时，但是这个句子中，so far距今为止，表示现在为止这个节日庆祝活动，还没有举办，要用将来时。

故选C。

考点: 考查句式用法4．Her own story ________ and this book is expected to come out next week.A．had been written B．has been writtenC．had written D．has written【答案】B【解析】句意：她自己的故事已经被写出来了，这部书有望下周出版。
