英语被动语态语法详解及例句分析

一、语态概述 英语的语态是通过动词形式的变化表现出来的.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.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. 主动态和被动态指的是动词形式,是词法概念；而主动句和被动句则指的是句子结构,从而是句法概念.所谓主动句就是由主动态动词(词组)作谓语动词的句子,而被动句则是由被动态动词(词组)作谓语动词的句子. 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“助动词be＋及物动词的过去分词”构成.人称、数和时态的变化是通过be的变化表现出来的.现以teach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＋taught 一般过去时：was／were＋taught 一般将来时：will／shall be＋taught 现在进行时：am／is／are being＋taught 过去进行时：have／has been＋taught 现在完成时：have／has been＋taught 歌诀是：被动语态be字变,过去分词跟后面. 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. 例如： Some new puters were stolen last night. 一些新电脑在昨晚被盗了.(不知道电脑是谁偷的) This book was published in 1981.这本书出版于1981年. (2)强调动作的承受者,而不强调动作的执行者. 例如：the window was broken by Mike.窗户是迈克打破的. This book was written by him.这本书是他写的. Eight hours per day for sleep must be guaranteed.每天8小时睡眠必须得到保证. 歌诀：谁做的动作不知道,说出谁做的没有必要； 动作承受者需强调,被动语态运用到. 四、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.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. 歌诀是：宾变主,主变宾,by短语后面跟. 谓语动词变被动,be后“过分”来使用. 五、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. 歌诀是：情态动词变动,情态加be加“过分”,原来带to要保留.例如： We can repair this watch in two days. This watch can be repaired in two days. You ought to take it away. It ought to be taken away. They should do it at once. It should be done at once. 这位朋友,以上是我为你解答的关于被动语态的语法详解及例句分析,希望是你满意答案.,9,

被动语态用法

英语中及物动词有两种语态，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。被动语态由“助动词be+及物动词的过去分词”构成。助动词be有人称、时态和数的变化。　　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.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.　　4.一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.　　5.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.　　6.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.　　7.不定式的被动语态：to + be + 及物动词的过去分词　　There are two books to be read. →　　There are twenty more trees to be planted.　　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。　　例：1.　Bruce writes a letter every week. →A letter is written by Bruce every week.　　2.　Li Lei mended the broken bike this morning.→The broken bike was mended by Li Lei this morning.　　3.He has written two novels so far.→Two novels have been written by him so far.　　4.They will plant ten trees tomorrow.→Ten trees will be planted by them tomorrow.　　5.Lucy is writing a letter now.→A letter is being written by Lucy now.　　6.You must lock the door when you leave.→the door must be locked when you leave.　　三、使用被动语态应注意的几个问题：　　1.不及物动词无被动语态。　　What will happen in 100 years.　　The dinosaurs disappeared about 65 million years ago.　　2.有些动词用主动形式表示被动意义。　　This pen writes well.　　This new book sells well.　　3.感官动词或使役动词使用省略to的动词不定式，主动语态中不带to ，但变为被动语态时，须加上to 。　　例：make somebody do something→somebody+ be +made to do something　　see somebody do something→somebody +be +seen to do something　　A girl saw my wallet drop when she passed by.→My wallet was seen to drop by a girl when she passed by.　　The boss made the little boy do heavy work.→The little boy was made to do heavy work by the boss. 　　4.如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。　　He gave me a book.→A book was given to me by him.　　He showed me a ticket.→A ticket was shown to me by him.　　My father bought me a new bike. →A new bike was bought for me by my father.　　5.一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。　　We can’t laugh him. →He can’t be laugh by us.　　He listens to the radio every day. →The radio is listened to by him every day.　　The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse.　　只要你掌握了以上一些方法，被动语态并不难学。***隐藏网址***

被动语态讲解

被动语态的结构是：助动词be+及物动词的过去分词。是动词的一种形式，用以说明主语与谓语动词之间的关系。eg. Saddam is being tried. 萨达姆正在接受审判。,被动语态时态变化只改变be的形式，过去分词不变。,     (一)举例,Saddam is being tried. 萨达姆正在接受审判。,The Iraqi government is trying Saddam. 伊拉克 *** 正在审判萨达姆。,More and more people use puters now.(主动语态),Computers are more and more widely used now.(被动语态),English is spoken all over the world. (被动语态),(二)英汉两种语言在表达被动方式上的差异,汉语表达被动语态非常简单明了，用“被”“遭”“受”等词来表示，如“被捕”、“被杀”、“受到 *** ”等。而英语表达被动的方式也不复杂，用“助动词be+动词的过去分词”表示。其中助动词be有人称、数量和时态的变化，而这正是英语被动语态的难点。,(三)被动语态的构成,被动语态由“be+及物动词的过去分词”构成。这里要强调一定是及物动词的过去分词，因为不及物动词不能带宾语，也就不可能有被动语态。英语主动语态有16个时态;被动语态常用的有8个，以give为例说明如下：,时态,动词形式,一般现在时,Am/is/are given,一般过去时,Was/were given,一般将来时,Shall/will be given,现在进行时,Am/is/are being given,过去进行时,Was/were being given,过去将来时,Should/would be given,现在完成时,Has/have been given,过去完成时,Had been given,被动语态的疑问句是将第一个助动词移到主语之前、句末用问号;否定式是在第一个助动词后加not或never等其他否定词、句末用句号。如：,“During the interview, were you asked questions in English?” “No, I wasn’t asked questions in English.” “面试的时候，用英语问你问题了吗?”“没有，没有用英语问我问题。”,The origin of the universe will probably never be explained. 宇宙的起源大概永远也不会被解释清楚。,Is the restaurant being decorated? 那家餐馆正在装修吗?,The restaurant is not being decorated. In the fact the restaurant has never been decorated。那家餐馆没有在装修。实际上，那家餐馆从来没有装修过。,(四)被动语态的用法,1、不知道或没有必要指出动作的执行者。换个说法，有一件事情不知道是谁干的或者不想说出是谁干的，这时就用被动语态。例如：,I felt a littlie nervous when I was being interviewed. 我接受面试的时候，有点紧张。,These fighters are imported from Russia. 这些战斗机是从俄国进口的。,That place has been turned into a swimming pool. 那个地方已被变成游泳池。,2、说话或发表意见时，为了显得客观公正，也常用被动语态,He’s said/believed/reported to be in the U. S. A. 据说/据信/据报道他在美国。,还有下列常用句型(that后面跟句子)：,It is said that……. 据说,It is reported that……. 据报道,It is hoped that……. 希望,It is believed that……. 人们相信,It is announced that……. 据宣布,it is (well) known that……. 众所周知,It has been decided that……. 已经决定,It is supposed that……. 人们认为,It is suggested that……. 有人建议,It must be remembered that……. 务必记住,It is taken for granted that……. 被视为当然,(五)主动句变被动句的注意事项,一是时态不能改变;二是变为被动语态后，谓语动词要和被动语态的主语在人称、数上保持一致。还要作如下变动：把主动语态的宾语变为被动语态的主语;主动语态的主语放在by的后面，组成介词短语，再把这个介词短语放在被动语态的谓语动词之后。在动作的执行者无须说明或不必要强调时，by短语可以省略。例如：,They will open a new supermarket there soon. 他们很快将在那里开办个新超市。,A new supermarket will be opened there soon. 一个新超市不久将在那里开办。,The doctor gave o lectures in English. 那位医生用英语讲了两次课。,Two lectures were given by the doctor in English. 由那位医生用英语讲了两次课。,Somebody has warned us to be careful of rats. 有人警告我们要当心老鼠。,We have been warned to be careful of rats. 我们受到警告，要当心老鼠。,如果主动语态有两个宾语(直接宾语和间接宾语)，变为被动语态时，可将其中任何一个宾语变为主语，另一个不变。但较常见的是将间接宾语变为被动语态的主语。,The reporters asked the president some questions. 记者们问了总统一些问题。,The president was asked some questions by the reporters. ( 变间接宾语为主语),Some questions were asked the president by the reporters. (变直接宾语为主语),We have given him a job. 我们已给了他一个工作。,He has been given a job. (变间接宾语为主语),A job has been given (to) him. (变直接宾语为主语),(六)含有情态动词的被动语态,句中含有情态动词时，其被动语态的结构是：情态动词+be+过去分词：,The timetable can be changed any time. 时间表随时可以改变。,This book may not be taken out of the reading room. 这本书不允许带出阅览室。,This dictionary must be taken good care of. 这本词典必须保管好。,(七)关于被动语态的几点说明,1、有些动词形式上是主动，意义上是被动。例如:,School begins in September. 学校九月份开学。,The library doesn’t open on Sunday. 图书馆星期天不开放。,The machine runs well. 这台机器容易操作。,My pen writes well. 我的钢笔好使。,The cloth washes well. 这料子耐洗。,The dictionary sells well. 这词典销路很好。,The book hardly sells. 这书买不出去。,The door will not shut/lock. 门关/锁不上。,2、make, see, watch, hear, notice, feel等使役动词和感官动词的宾语后面可以接不带to的不定式作宾补。但在被动语态中，不定式符号to必须补上。例如：,They made him go. 他们让他去。,He was made to go. 他被要求去了。,I heard him say good-bye to his friends. 我听见他向他的朋友说再见。,He was heard to say good-bye to his friends. 有人听到他向他的朋友说再见。,3、除助动词be外，动词get有时也可跟过去分词构成被动语态，是比较口语化的一种被动语态。这种结构中很少用by短语。例如:,I got lost in the huge market. 在那个巨大的市场中我迷失了方向。,You might get killed/hurt. 你会送命/受伤的。,In the end this story got translated into English. 这故事最后被译成了英文。,His car got damaged in a road accident.  他的车在交通事故中被毁了。,4、“have/get+宾语+过去分词”这个句型也表达了一种被动的意思。如：,I’ll have the bike repaired in no time. 我一会就把自行车修好。,I had my wallet stolen/lost last Sunday when I was shopping. 上星期天买东西的时候我的钱夹被盗。,He got his leg broken when playing football.  踢足球的时候他把腿弄断了。,I bought these books at a discount and had o hundred dollars saved. 我打折买了这些书，省了两百美元。,5、在need, want, require后面，主动的-ing形式表达被动的意思：,My watch needs cleaning. (=…needs to be cleaned) 我的表需要清洗。,Your garden needs watering. (=…to be watered) 你的花园需要浇水。,Does your suit require pressing, sir? 先生，您的衣服要烫吗?

希望大家能讲解一下被动语态具体怎么一回事讲详细点每一点都说

分类: 外语/出国 解析: 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 apple．（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．→The 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。如： We call him Xiao Wang．→He is called Xiao Wang． He cut his hair short．→His hair was cut short． They told him to help me．→He was told to help me． 5）短语动词是不可分割的整体，改为被动语态时要保持其完整性，介词或副词不可遗漏。如： We must take good care of the young trees．→The young trees must be taken good care of． 6）含有宾语从句的主动结构变为被动结构时，通常用it作为被动结构的先行主语，从句放在句子后面；也可采用另一种形式。可以这样转换为被动结构的动词有know，say，believe，find，think，report等。如： People believe that he is ill．→It is believed that he is ill．（或：He is believed to be ill．） 3． 被动语态改为主动语态的方法： 被动语态中介词by后的宾语改为主动语态中的主语（或按题意要求确定主语），按照这个主语的人称和数以及原来的时态把谓语动词形式由被动语态改为主动语态。注意在主动语态中有的动词要求不带to的动词不定式作宾语补足语，此时要把被动语态中的to去掉。被动语态的主语用来作主动语态的宾语。如： History is made by the people．?The people make history． 4． 不能用于被动语态的情况 1）某些表示“静态”的及物动词（表示状态而不是动作，而且常常是不可用于进行时态的动词）如have，fit，suit，hold（容纳），cost， suffer，last（持续）等不能用于被动语态。如： They have a nice car．他们有一辆漂亮的汽车。 My shoes don’t fit me．我的鞋不合适。 My brain can’t hold so much information at one time．我的脑子一下子记不住这么多资料。 How much ／What does it cost？这值多少钱？ Our holiday lasts 10days．我们的假期有十天。 This food will last（them）（for）3days．这食物足够（他们）（吃）三天。 2）不是所有带介词的动词都能用于被动结构。若是构成成语动词通常有被动态，若不构成成语动词则无被动态。试比较： They arrived at a decision．?A decision was arrived at．他们作出了决定。 They arrived at the station．他们到达车站。（不说：The station was arrived at．） He looked into the question．?The question was looked into．他调查了这个问题。 3）动词leave（离开），enter（进入），join（参加）不可用于被动语态。如： The car left the road and hit a tree．车子离开了道路，撞上了树。 4）某些及物动词可作不及物动词用，特别是后加副词（如well， easily等）时。主动语态有被动含义，这类动词常见的有sell，write， wear，wash，cook，open，close，lock，read，record等。如： His new novel is selling well．他的新小说很畅销。The cloth washes well．这布很耐洗。 This material won’t wear．这种材料不耐穿。His play won’t act．他的戏剧不会上演。 The window won’t shut．这窗关不上。The door won’t open．这门打不开。 The door won’t lock．这门锁不上。This poem reads well．这首诗读来很好。 5）feel，look，appear，sound，taste， *** ell等由实意动词演变而来的系动词，后接形容词作表语，不可用于被动语态。如： Tell me if you feel cold．你要是感到冷就告诉我。 You’re looking very unhappy?what’s the matter？你看来很不高兴???怎么回事儿？ The soup tastes wonderful．这汤味道好极了。 Those roses *** ell beautiful．那些玫瑰好闻极了。 She appears to be friendly．她看上去很友好。 6）宾语是不定式或动词的或-ing形式时，不可用于被动语态。如： Peter hoped to meet her．彼得希望遇见她。 Mr Smith enjoyed seeing his daughter．史密斯先生喜欢看他的女儿。 7）宾语是反身代词或相互代词时，不可用于被动语态。如： She can dress herself．她可以自己穿衣服。 We could hardly see each other in the fog．在雾中我们彼此几乎看不见。 8）宾语是同源宾语时，不可用于被动语态。如： They live a happy life．他们过着幸福的生活。 The girl dreamed a sweet dream ．那女孩做了个甜美的梦。 9）宾语带有与主语有照应关系的物主代词时，不可用于被动语态。如： The old man broke his（＝the old man’s）legs．那老人把自己的腿弄断了。 The girl shook her（＝the girl’s）head．那女孩摇了摇头。 5． 某些动词的主动形式表被动含义 英语中有很多动词如act，break，catch，cut，clean，drive，draw， let，lock，open，sell，read，write，wash，wear等，当它们被用作不及物动词来描述主语特征时，其主动形式常用来表达被动含义。另外，像 owe，beat，cook，bake，print，build，make等，有时可以用主动形式表达被动含义。如： This kind of radio doesn’t sell well．这种收音机不太畅销。 The shop opens at eight o’clock．这个商店八点开门。 The pipe does not draw well．这烟斗不太通畅。 These plays act wonderfully．这些剧演得好。 Kate’s book reads like an interesting novel．凯特的这本书读起来像本有趣的小说。 注意：主动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。如： The door won’t lock．门锁不上。（指门本身有毛病） The door won’t be locked．门不会被锁上。（指不会有人来锁门） His novels sell easily．他的小说销路好。（指小说本身内容好） His novels are sold easily．他的小说容易销售。（主要强调外界对小说的需求量大） 6．某些动名词的主动形式表被动含义 1）在need，want，require，deserve和bear等词的后面，动名词用主动形式表示被动含义，其含义相当于动词不定式的被动形式。如： The house needs repairing（to be repaired）．这房子需要修理。 My clothes need washing（to be washed）．我的衣服需要洗了。 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。如： The picture-book is well worth reading．（＝The picture-book is very worthy to be read．）这本画册很值得一读。 Such a man as Mr．Smith is not worth helping．（＝Such a man as Mr．Smith is not worthy to be helped．）像史密斯先生那样的人不值得帮助。 This plan is not worth considering．（＝This plan is not worthy to be considered．）这个计划不值得考虑。 3）某些动词不定式的主动形式表被动含义 a．当nice，easy，fit，hard，difficult，important，impossible，pleasant， interesting等形容词后跟不定式作状语，而句子的主语又是动词不定式的逻辑宾语时，这时常用不定式的主动形式表达被动含义。如： Japanese is not difficult to learn．日语并不难学。（指日语被学） The water is unfit to drink．这水不适合喝。（指水被喝） The piece of music is pleasant to hear．这首音乐听起来很悦耳。（指音乐被听） This book is easy to read．这本书读起来很容易。（指书被读） b．当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，不定式的主动形式表示被动含义。如： I have a lot of work to do today．我今天有很多工作要做。（work to do指被做的工作） He has three children to look after．他有三个孩子要照看。（children to look after指孩子被照看） 注意：如果以上句型用动词不定式的被动形式，其含义有所区别。如： I have some clothes to be washed．我有些要洗的衣服。（衣服不是自己洗） c．在there be．．．句型中，当动词不定式修饰名词作定语时，不定式用主动或被动式，其含义没有什么区别。如： There is a lot of homework to do（to be done）．有很多家庭作业要做。 There are some clothes to wash（to be washed）．有些衣服要洗。 4）由介词for，on，above，under等构成的短语有时可以表达被动含义。如： His paintings will be on show tomorrow afternoon．＝His paintings will be shown tomorrow afternoon．他的油画作品明天下午展出。 5）表示感官意义的连系动词如 *** ell，feel，taste，look，sound等在句子中常表达被动含义。如： How nice the music sounds！这音乐听起来多悦耳！ Good medicine tastes bitter．良药苦口。 Our school looks more beautiful than before．我们学校看上去比以前更漂亮了。在主动语态中,使让动词(make,have,let)和感官动词(see, look,watch,notice,listen,hear,feel,find)后必省略to,但在被动语态中必须加上to 例:在教室里我们听见他唱了这首歌 we heard him sing this song in the classroom. he was heard to sing this song by us in the classroom. 大概也就这样了

被动语态的详细讲解

被动语态： 1：英语中语态有两种：主动语态和被动语态。 语态的作用：语态是动词的一种形式，用来说明主语和谓语之间的关系。 语态的选用：如果主语是动作的执行者，谓语用主动语态。 例如：We clean the room every day. 如果主语是动作的承受者，或者说是动作的对象，谓语则是要用被动语态。 例如：The room is cleaned every day. 被动语态由“助动词be + 急务动词的过去分词”构成。助动词be 有人称、数和事态的变化，其变化规则与be 作为连系动词时完全一样。 2：被动语态的各种形式 1) am/is/are +done eg1：I’m asked to take care of myself. Football is played all over the world. eg2：Football is not played all over the world. eg3: Is football played all over the world? 这些玩具是中国制造的。 这个小偷是在那家超级市场被抓住的。 2）has /have been done eg1：This book has been translated (翻译) into many foreign languages. eg2：This book has not been translated into many foreign languages. eg3: Has this book been translated into many foreign languages? 那两把伞已经送给了我父母。 今天这首歌已经被唱了几次了？ 3）am/is /are being done eg1：A road is being built around the mountain. eg2：A road is not being built around the mountain. eg3: Is a road being built around the mountain? 我们不能搬进新房间因为它正在油漆。 4） was/were done eg1：This house was built in 1958. eg2：This house was not built in 1958. eg3: Was this house built in 1958? 昨天上午这条裙子被卖走了。 我的书在哪里？刚才它被放在桌子上得。 5) was/were being done eg1：Meeting was being held when I was there. eg2：Meeting was not being held when I was there. eg3: Was meeting being held when you were there? 6) shall/will be done eg1：He will be taken to hospital tomorrow. eg2：He will not be taken to hospital tomorrow. eg3: Will he be taken to hospital tomorrow? 动物园的动物马上要喂养了。 3：练习 1).

被动语态讲解一下哦！~~

被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以teach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＋taught 一般过去时：was／were＋taught 一般将来时：will／shall be＋taught 现在进行时：am／is／are being＋taught 过去进行时：had been＋taught 现在完成时：have／has been＋taught另外不能用于被动语态的情况 1）某些表示“静态”的及物动词（表示状态而不是动作，而且常常是不可用于进行时态的动词）如have，fit，suit，hold（容纳），cost， suffer，last（持续）等不能用于被动语态。如： They have a nice car．他们有一辆漂亮的汽车。 My shoes don’t fit me．我的鞋不合适。 My brain can’t hold so much information at one time．我的脑子一下子记不住这么多资料。 How much ／What does it cost？这值多少钱？ Our holiday lasts 10days．我们的假期有十天。 This food will last（them）（for）3days．这食物足够（他们）（吃）三天。 2）不是所有带介词的动词都能用于被动结构。若是构成成语动词通常有被动态，若不构成成语动词则无被动态。试比较： They arrived at a decision．?A decision was arrived at．他们作出了决定。 They arrived at the station．他们到达车站。（不说：The station was arrived at．） He looked into the question．?The question was looked into．他调查了这个问题。 3）动词leave（离开），enter（进入），join（参加）不可用于被动语态。如： The car left the road and hit a tree．车子离开了道路，撞上了树。 4）某些及物动词可作不及物动词用，特别是后加副词（如well， easily等）时。主动语态有被动含义，这类动词常见的有sell，write， wear，wash，cook，open，close，lock，read，record等。如： His new novel is selling well．他的新小说很畅销。The cloth washes well．这布很耐洗。 This material won’t wear．这种材料不耐穿。His play won’t act．他的戏剧不会上演。 The window won’t shut．这窗关不上。The door won’t open．这门打不开。 The door won’t lock．这门锁不上。This poem reads well．这首诗读来很好。 5）feel，look，appear，sound，taste，smell等由实意动词演变而来的系动词，后接形容词作表语，不可用于被动语态。如： Tell me if you feel cold．你要是感到冷就告诉我。 You’re looking very unhappy?what’s the matter？你看来很不高兴???怎么回事儿？ The soup tastes wonderful．这汤味道好极了。 Those roses smell beautiful．那些玫瑰好闻极了。 She appears to be friendly．她看上去很友好。 6）宾语是不定式或动词的或-ing形式时，不可用于被动语态。如： Peter hoped to meet her．彼得希望遇见她。 Mr Smith enjoyed seeing his daughter．史密斯先生喜欢看他的女儿。 7）宾语是反身代词或相互代词时，不可用于被动语态。如： She can dress herself．她可以自己穿衣服。 We could hardly see each other in the fog．在雾中我们彼此几乎看不见。 8）宾语是同源宾语时，不可用于被动语态。如： They live a happy life．他们过着幸福的生活。 The girl dreamed a sweet dream ．那女孩做了个甜美的梦。 9）宾语带有与主语有照应关系的物主代词时，不可用于被动语态。如： The old man broke his（＝the old man’s）legs．那老人把自己的腿弄断了。 The girl shook her（＝the girl’s）head．那女孩摇了摇头。
