英语被动语态的问题好像被动语态中有一些单词是没有被动语态的,比如happen,请再列举出一些没有被动语态的单词

must为必须,肉必须不能再烤箱里放太久

How many kilograms of water is needed for our body every day?或者更简洁地表达How much water is needed for our body every day?
因为WATER是不可数名词啊

正确

一般现在时：be done 一般过去时：be(过去式)done 一般将来时：will be done 或是 be going to be done 现在完成时：has been done 过去完成时：had been done 现在进行时 isamare+being done 过去进行时 waswere+being done 情态动词：情态动词（must can could may maight shall should 等） +be done 不定式：to be done 如果被动语态涉及到过去,只把be[am is变was,are 变 were ]动词变成相应的过去式 情、助、有、是妥安排,一律随新主语变.否定助后加not,疑问一助置主前.主语恰是疑问词,直陈语序主在前.一般情助加be done,双宾多将间宾变.复合宾语宾变主,宾补、主补相应变.

A是一个固定的用法 卖的很好 并不是被卖光了的那种 所以我们用sold out 但不用sold well
TO是不可以去掉的 因为listen to是固定的搭配
某些动词如cut,drive,pay,write,read,sell,keep,prove,weigh,number,drink,wear,pay,wash,open,cost,lock,last等常用主动形式表被动含义,这时常和well,easily,perfectly,badly,slowly等方式副词连用,这种用法多用来说明主语的特征、性质或所处的状态等.例如：
The pen writes quite smoothly．
The book sells well.

首先这2句话都是被动语态
翻译为：1.不得不/必须提供成百上千的公交车
2.有很多的事情必须去做/去完成 （翻译的时候可意译,在不强调的情况下没必要翻译“被”字）
1句中 had to 是不得不,必须的意思（其原型为have to,had to 为它的一般过去式）
2句中因为must为情态动词 所以后面要用动词原型 即be 而不用am is are
被动语态的基本结构 是 be+动词过去分词 ,be的形式有am is are was were等来体现不同时态,只是此处用在情态动词must后只能用原型be）

过去时
The guests were introduced to Jane.客人们被介绍给了简
The situation was explained to me.情况想我说明了
The food was cooked last night.饭是昨天晚上做的
This wallet was found in the street.这个钱包是在街上捡到的.
This pen was given me by Tom.这支笔是汤姆给我的.
一般现在时
The food is cooked by Jason.饭是杰森做的.
Xiao Wang,you are wanted in the offices.小王,办公室有事找你.
I am not so easy deceived.我不会轻易上当受骗.
A sound of piano is heard in the room.听到房间里有钢琴声.
Hundreds of people get killed every year by traffic on the roads.每年都有数百人死于道路交通事故
希望以上能帮到你.
如果有可能,可以买本语法书,上面有很多例句.

因为原来主动语态的宾语现在变主语了,所以没宾语了.如i have finished the job .变成the job has been finished.

1.These applles (D) well because they ( ) nice.
A.are sold;look B.seel;look C.sell;are looked D.are sold;are looked
选B.你打字错了,应该是sell.
sell well销路好,要用主动表被动.look看起来,是联系动词,没有被动.
拓展：些系动词,如feel,look,seem,appear,taste,sound,smell,prove,remain等用主动形式表示被动意义；主语通常是事物,且表示该事物本身具有某一固有特征.如：
The material feels very soft.这种料子摸起来很柔软.
2.What about the pen you bought yesterday?
It (B) well.I like it very much.
A.was written B.is written C.wrote D.writes
选D.和第一题一样,write well,也要用主动表被动.
拓展：表示主语由内在品质或性能,使得主语得以实现或不能实现,用主动表示被动,常见的这类动词有：write,read,clean,sell,wash,cook,open,close,lock等.
1.同well,badly,easily等副词连用.如：
The cloth washes easily.这布很好洗.
The book sells well.那本书很畅销.
The pen writes smoothly.这支笔很好写.
3.I feel very happy that I (B) to be the host.
Congratulations!
A.choose B.am chosen C.was chosen D.haven chosen
选C.我被选为主持人感到很高兴.
4.Have all the students known that our class will visit the factory this afternoon?
Yes,every student (C) about it.
A.have told B.have been told C.has told D.has been told
选D.
every修饰单数名词,谓语动词用单数,所以排除了B.每个学生被告知了这件事,所以用被动.
tell的主动式要跟双宾语.即tell sb sth.
5.Mr Johnson's story ( D) by everyone who heard it.
A.laughed at B.was laughed C.laughed D.was laughted at
选D.后面有by,前面要用被动式.laugh at sb/sth在改为被动语态时别漏掉介词at.
6.Students ( C) slippers when they are at school.
A.don't allow to wear B.are not allowed to wear
C.are not allowed to put on D.are not allowed wearing
选B.allow sb to do sth.改为被动：be allowed to do sth.
用wear表示穿着的状态,而put on表示穿上的动作,所以C是错误的.

the book is writen by Luxun

相信所有的付出都会有回报 ,他总是努力的工作
首先是reward和award的区别啊
reward是报酬,回报,酬劳,而award是奖励,CD就排除了阿
然后被动 选B

1.当句子的主语是动作的执行者时,谓语的形式是主动语态.当句子的主语是动作的承受者时,谓语要用被动语态.被动语态由助动词be+过去分词构成,时态通过be表现出来.例如：
1）一般现在时：You are required to do this.
2）一般过去时：The story was told by her.
3）一般将来时：The problem will be discussed tomorrow.
4）现在进行时：The question is being discussed in the meeting room.
5）过去进行时：The new road was being made.
6）现在完成时：The novel has been read.
7）过去完成时：He said that the work had been finished.
8) 过去将来时：He said that the trees would be planted soon.
2.一些特殊的被动结构
1）带情态动词的被动结构：
The problem must be solved soon.
2）带不定式的被动结构：
The homework needs to be done with care.
3）短语动词的被动结构：
例1）The baby is looked after carefully.
用于这类被动结构的短语动词要把它们作为整体看待.这类结构有以下几种：
①（不及物）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.
②（及物）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.
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等.
例 2) Attention must be paid to your pronunciation.
用于这类被动结构的短语动词最多见的是“动词+名词+介词”这一结构.如：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.
例 2与例1的不同点在于,它们用于被动时态能有两种形式.第一种形式是把“动词+名词+介词”作为整体看待.第二种形式是把其中的“动词+名词”作为“动词+宾语”的结构处理.
4）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.)

1I was asked to call on him the next day by him
2This novel haven't been finished by me
3Is this the car driven by the young lady?
4Your bicycle had been found by them

大概是这样的:1she often heard sung the song(by us)2we are being taught english by miss ding3my parent was infiuenced to me4when these cars were made by them5a new dig school will be built by us in two...

被动语态的基本结构为“be+过去分词”,将此基本结构像其它短语一样套入主动语态各时态的结构中即可.

1. 英语被动语态中体现不出主语时,需要体会句子含义,进行相应的变化.
至于到底怎么变,要看具体句子而定,没有固定的说法.
如：The novel was written in 1998.
可以变成：Somebody wrote the novel in 1998.
2. 被动语态划分句子成分的时候,主语就是被动动作的承受者.
如The novel was written in 1998.的主语就是the novel.

1 相信自己,这道你是对的
2 对
3应该是：She was seen to go into the teachers' office a moment ago
以上两个动词都是相同的结构,它们后接省去TO 的动词不定式作宾语补足语.变被动语态时要用回TO ,即；see/ make sb do sth 主动结构-> sb be seen / made to do sth 被动结构
要牢记哦!

这个涉及到非谓语的知识
非谓语包括：doing,to do,done其中：
done表示已完成和被动,要看句子的主语
doing表示正在进行,伴随或主动,要看句子的主语.
to do表示将来时态
看主语主要是说看谓语动词和主语的关系.
这个句子中谓语是name,主语是rat,构成了被动,可以用done来表示被动.

are be bookedIs written&nb...

C (look在这里做系动词,类似於be动词,而其他选项不能这样用)
A (be worth doing ,TV要接watch)
C (need doing=need to be done)

1 I was surprised by the news (fact)that they would not give him a holiday after his hard work.
其实就自己加个宾语就好了
2 Could the plan be carried out on time?

A test is going to be had tomorrow.
Computers is allowed to use.

D
see sb do sth 被动：sb be seen to do sth
see sb doing sth 被动 ：sb be seen doing sth
感官动词+ sb＋do 是一个省to的不定式
因此,在改成被动时,要加上to

16种被动语态.
1 一般过去was/were done
2.一般现在is/are done
3.一般将来 will be done
4.（一般）过去将来would be done
5.过去进行was/were being done
6.现在进行is/are being done
7.将来进行will be being done
8.过去将来进行would be being done
9过去完成had been done
10现在完成have/has been done
11将来完成will have been done
12过去将来完成would have been done
13过去完成进行had been being done
14现在完成进行have/has been being done
15将来完成进行will have been being done
16过去将来完成进行would have been being done

1B.do make sb.do sth.
2B.fit
A选项是被字句,翻译为,这些石头被适合好 - - No..翻译不通..
B正确 因为There stones 是复数,
C选项是三单形式,- - 看看B就知道了是错的了..
D选项也是被字句,而且是单数的被字句,和A差不多,翻译不通,单复数也不对,so
3B.costed cost的主语一定是doing sth 或者是sth.不可以是人,

被动语态,即不知道动作执行者或强调动作承受者的一种语态.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.被动语态表示主语是动作的承受者,即行为动作的对象.
英语被动语态的构成通常是：“Be+Passive”.但“Get+Passive”也可以构成被动语态,用这种结构的句子侧重于动作的结果而不是动作本身.如： The man got hurt on his way home. 那个男人在回家的路上受伤了. How did the glass get broken? 杯子怎么破了?
各种时态和句型如下：
　　①一般时（一般现在,一般过去,一般将来）：am, is, are, was, were, is going to be , will be+done . 例如： Once environmental damage is done, it takes many years for the system to recover. 本句的意思是：“环境一旦遭到破坏,需要多年时间才能恢复过来.”do作为及物动词有“引起,产生”的含义,do damage的意思是“造成破坏”.主语damage是及物动词do的动作对象,谓语应当用被动语态.同样的,还有,I will mend the machine.相当于The machine will be mended （by me）.
　　②进行时（现在进行、过去进行）：be+being+P.P. 例如：The classroom is being cleaned.
　　③ 完成时（现在完成、过去完成、将来完成）：have/has been + P.P.：例如The machine will have been repaired by 3 o’clock this afternoon.再如：My homework has been finished.
　　④ 其他时态 以此类推,可得到结果.
　　⑤ 情态动词的被动语态：主语 + 情态动词 + be动词 + 动词过去分词,例如Your teeth must be brushed.
　　⑥ 不定式的被动语态：to be done例：The no-shows have to be considered when deciding the rate of overbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人.）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.
　　8.过去将来时的被动语态：would + be + 及物动词的过去分词
　　He said he would finish the work soon.
　　He said the work would be finished soon by him.
主动语态改被动语态　　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.
使用被动语态的注意问题　　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 . 感官动词有smell,sound,taste,fell等.使役动词有let,make,have,help,hear,see,watch,notise,look,listen.
　　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.
　　His mother gave him a present for his birthday.→ He was given a present by his mother for his birthday.
　　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 at him. →He can’t be laughed at 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.
　　6.宾语补足语的被动语态
　　They call him Bob./He is called Bob.　
　　7.谓语补助语态
　　He is a bad boy.

Some toys were found by us in a box.The pupils was kept by the teacher at school.A parcel has been left by James for you.The article must be finish by you before Friday.The house will not be painted by them again next year.Mary was promised by them a new doll.Where was the story translated by him?When was this new TV bought by you?Does the sick be taken good care of by them.The workers wages has been paid by the company.

一、注意被动语态的不同时态被动语态由“be+过去分词”,其中的助动词 be 根据情况可使用各种不同时态.如：She is respected by everyone. 她受到大家的尊重.(一般现在时)The book will be reprinted soon. 这本书很快会重印.(一般将来时)The road is being repaired. 路正在修整.(现在进行时)They have been given a warning.
他们受到警告.(现在完成时) 二、注意带情态动词的被动语态该结构的基本形式为“情态动词+be(或be的适当形式)+过去分词”.这类结构非常有可能作为语境题出现在考卷中.如：The rules must be obeyed. 这些规章制度必须遵守.They shouldn’t have been told about it. 这事是不应当告诉他们的. 三、注意非谓语动词的被动语态1. 不定式一般式的被动语态.由“to be+过去分词”构成.如：She asked to be given some work to do. 她要求给她一些工作做.He was the last person to be asked to speak. 他是最后被邀请发言的人.2. 不定式完成式的被动语态.由“to have been+过去分词”构成.如：I should like to have been told the result earlier. 我本想让人把结果早点告诉我的.3. 现在分词一般式的被动语态.由“being+过去分词”构成.如：I saw him being taken away. 我看见有人把他带走了.Being protected by a wall, he felt quite safe. 有墙作保护,他感到很安全.4. 现在分词完成式的被动语态.由“having been+过去分词”构成.如：Having been invited to speak, I’ll start making preparations tomorrow. 因为邀请我去讲话,我明天就得做准备.因为邀请我去讲话,我明天就得做准备.The subject having been opened,he had to go on with it. 话题已经开始了,他不得不谈下去.5. 动名词一般式的被动语态.由“being+过去分词”构成.如：She likes being looked at. 她喜欢被人瞧.He hates being made a fool of. 他讨厌被别人愚弄.This question is far from being settled. 这个问题远没解决.6. 动名词完成式的被动语态.由“having been+过去分词”构成.如：Jenny’s not having been trained as a dancer is her one regret. 杰妮没受过舞蹈的专业训练是她感到遗憾的事.After having been instructed to drive out of town, I began to acquire confidence. 在接到把车开出城的指令后,我开始信心十足了.注：过去分词没有被动式,因为它本身可以表示被动意义.如：The door remained locked. 门仍然锁着. 四、注意“get+过去分词”构成的被动语态英语被动语态通常由“助动词be+过去分词”构成,有时也可用“get+过去分词”过去分词构成.如：James got beaten last night. 詹姆斯昨晚被打了.How did that window get opened? 那个窗户是如何打开的?但总的说来,用get构成的被动语态不如用be构成的被动语态常见,尤其是在含有施动者的by短语时,用get构成被动语态更是少见.不过有时用be+过去分词构成被动语态构成误解时,人们可能会选get+过去分词来避免这种误The window was broken. 窗户破了(表状态)./ 窗户被打破了(表动作)The window got broken. 窗户被打破了(表动作) 五、注意哪些动词不用于被动语态五、注意哪些动词不用于被动语态B>1. 不及物动词没有被动语态.因为不及物动词没有宾语,所以若将其用于被动语态则没有主语,故不能用于被动语态.但是值得注意的是,有些英语中的不及物动词,译成汉语时却可能是“及物”的,很容易出错,这类动词如：take place(发生),happen(发生),)come about(发生),break out(爆发),appear(出现),disappear(消失),last(持续),arise(出现,发生)等：Influenza usually breaks out in winter. 流感通常发生在冬季.Use this money when the need arises. 有需要时就使用这笔钱.2. 英语中的静态动词(如have, lack, fit, hold, suit, resemble 等)通常不用于被动语态：My shoes don’t fit me. 我的鞋不合适.The young man lacks experience. 这个年轻人缺乏经验.< experience. lacks> 六、注意两类被动句型的相互转换英语中有一种主动句可以转换成两种被动句型,它们通常是一些表示客观说明的句子.如：People believed that she is honest. 大家相信她是诚实的.It’s believed that she is honest. 大家相信她是诚实的.She is believed to be honest. 大家相信她是诚实的.比较上面两类被动句型可以发现,一类是“it+be+过去分词+that“it+be+从句”,另一类则是“主语+be+过去分词+不定式”(其中的“主语”为前一类句型中that从句中的主语ace=宋体>为前一类句型中),通常可用于这两类被动句型的动词有assume, believe, expect, fear, feel, know, presume, report, say, suppose, think, understand等,比较(同时注意其中时态和动词形式的变化)：It’s known that he was a good singer. / He is known to have been a good singer. 大家知道他曾是位优秀的歌手.It’s reported that he was driving fast. / He is reported to have been driving fast. 据说他当时车开得很快. 七、注意主动表被动的若干情形
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.如：That dog looks dangerous. 那只狗看起来很危险.My advice proved to be wrong. 我的意见证实是错的.我的意见证实是错的.2. 当open, 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.如：The door won’t shut. 这门关不上.The window won’t lock. 这窗户锁不住.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,只是不用关上)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.如：The cloth washes well. 这种布料好洗.His book doesn’t sell well. 他的书不好销.This shirt will wear very long. 这衬衫可以穿很久.The parcel carries easily. 包裹容易搬运.注：该用法通常与well, easily, slowly, quicklywell, easily, slowly, quickly等副词连用,并且在用于以上意思时通常不宜直接使用被动语态形式,如下面这道高考题答案是A,而不是C：Books of this kind _____ well. (1999年上海卷)A. sell B. sells C. are sold D. is sold4.权责声明：本站所有音乐均网上搜集仅做宽带测试,任何涉及商业盈利目的均不得使用,否则后果自负!如遇英文歌曲不能播放,系歌曲链接失效,请谅解!本站全部英文歌曲的所有权归其唱片公司或歌手所有.请购买正版英文歌曲支持你的偶像!

主动结构:主语+谓语+宾语(直接宾语+间接宾语)
被动结构:(直接)宾语+be+谓语过去分词(+间接宾语)+by主语
如果有间接宾语就用括号里内容
尽管语态有变化,但时态不变
例:
1.简单的主动结构:
The boy ate a apple.
主语:The boy
谓语:ate
宾语:apple
->A apple was eaten by him.
2.带有间接宾语的结构:
He gave the boy a ball.主语:he
谓语:gave
直接宾语:the boy
间接宾语:a ball.
->The boy was given a ball by him.
简单就概括成这样,如还有疑问可以问我.

一般现、过用be done,be有人称、时、数变.
完成时态have done,被动将been加中间.
一般将来shall (will) do,被动变do为be done.
将来进行无被动,shall (will) be doing,
现在完成进行同,have (has) been doing.
现、过进行be doing,被动be加being done.

e done 一起作谓语

The setting did not checked by you before opening your new e-dictiaoary.
方法就是找到原文中的宾语,这句子中就是settings了,被动的意思就是将宾语前置,形式为宾语+ be动词+ 一般动词的过去完成时+ 主语
单数和不可数名词用am/is/was 其中现在时用am/is过去时用was
复数现在时用are,过去时用were
如
I take the book.------The book is taken by me.
The news surprised me.-----I was surprised by the news.
补充问题中,用was和is 都可以

中文和英文都有主动语态、被动语态的语法.
比如你的题目中三个句子,1、3是被动态,2是主动态.中文中的被动语态不一定需要必须说出“被”字,主要看句子结构,放在句子前面的主语结构是动作的实施对象,就是被动语态.
你的问题补充中,“你吃了吗”是省略了“饭”这个实施对象,改成被动语态的时候,不能省略这个对象,所以要改成“饭吃了吗”.还有一个,“病被治好了吗”实际上也是省略了实施主体的,就是治病的“医生”,所以改成主动语态的时候不能省略这个主体,要改成“医生治好你的病了吗”.
所以,主动、被动语态,最主要的就是要看我们强调的是哪个方面,如果强调的是动作的实施主体,就用主动语态,于是实施的对象就无关紧要了；如果强调的是动作实施的对象,就用被动语态,这时实施的主体就可有可无了.
主动语态指主语是谓语动作的使动方.也就是说谓语的动作源自主语,而施加于宾语.相反,被动语态中,主语是谓语动作的受动方,如果有宾语的,宾语往往是谓语动作的使动方.
在语法机构上,主动语态和被动语态的区别主要在于,主动语态直接使用动词原形作为谓语,然后再在该动词原形的基础上施加时态和其他语法；而被动语态则使用系词+动词的过去分词作为谓语,各种时态和其他语法也施加在系词上.
举例：
主动：The snowslide killed him.
被动：He was killed by the snowslide.
意义均为：他死于雪崩.
英语中的被动语态使用得比汉语要多,要普遍,许多课本乃至实际应用中都常常涉及到这个问题.一般说来,当强调动作承受者,不必说出执行者或含糊不清的执行者时,多用被动式.须注意的是,许多地方与汉语不同.注意那些汉语中没有"被……"的意思,英语却用被动态.还要注意,英语的被动态往往由"by"引出,而有用介词"by"的短语往往又不是被动态,而是系表结构.还有些待殊现象,如…known to man(人类.所知),on foot步行(美国人有时用by foot),in carraige(乘四轮马车)等等.还有假主动,真被动的十几个常用词的用法,以及so heavy to carry而不用so heavy to be carried等习惯用法.有关这类情况,做到心中有数对全面掌握被动态,准确无误地解答习题非常关键,被动态必须涉及的是动词的各种时态变化的问题.英语的时态本来很复杂,怎样记住各自的被动形式呢? 首先要明确"将来进行无被动,现在完成进行
同".这两种时态无被动形式.
另外,不及物动词带有同源宾语的动词,反身代词的动词和系动词都无被动形式.即便如此,还有不定式,动名词,分词,以及它们的复合结构)的被动态,再加上情态动词,助动词以及它们的疑问式和否定式从中掺杂,真是令人头痛,眼花缭乱.下面口诀就以动词do为例,即do did过去式done过去分词,以口诀形式总结各种时态的被动态,一定对你有所启示.
被动语态（一般现在时）
主动语态变被动语态时,主动语态句中的宾语变成被动语态句中的主语,主动语态句中的主语成为被动语态句中的动作的发出者.
《被动语态的口诀》
一般现、过用be done,be有人称、时、数变.
完成时态have done,被动将been加中间.
一般将来shall (will) do,被动变do为be done.
将来进行无被动,shall (will) be doing,
现在完成进行同,have (has) been doing.
现、过进行be doing, 被动be加being done.
情、助、有、是妥安排,一律随新主语变.
否定助后加not,疑问一助置主前.
主语恰是疑问词,直陈语序主在前.
一般情助加be done,双宾多将间宾变.
复合宾语宾变主,宾补、主补相应变.
特别注意：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：
appear, die disappear, end (vi. 结束), fail, happen, last, lie, remain, sit, spread, stand
break out, come true, fall asleep, keep silence, lose heart, take place.
After the fire, very little remained 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.特别是一词多义的动词往往有两种用法.解决这一问题唯有在学习过程中多留意积累.
2) 不能用于被动语态的及物动词或动词短语：
fit, have, hold, marry, own, wish, cost, notice, watch agree with, arrive at / in, shake hands with, succeed in, suffer from, happen to, take part in, walk into, belong to
This key just fits the lock.
Your story agrees with what had already been heard.
3) 系动词无被动语态：
appear, be become, fall, feel, get, grow, keep, look, remain, seem, smell, sound, stay, taste, turn
It sounds good.
4) 带同源宾语的及物动词,反身代词,相互代词,不能用于被动语态：
die, death, dream, live, life
She dreamed a bad dream last night.
5) 当宾语是不定式时,很少用于被动语态.
(对) She likes to swim.
(错) To swim is liked by her.PS:
编辑本段有些动词可以带双宾语
在用于被动结构时,主动结构中的间接宾语变为主语时,直接宾语仍然保留在谓语后面；直接宾语变为主语时,直接宾语前通常加上介词for/to
He was asked a number of questions at the press conference.在记者招待会上人们问了他很多问题
They are taught a lot of things in the kindergartens.他们在幼儿园被教给很多东西.
A new MP4 was given to him as birthday present/gift.作为生日礼物他收到了一个新MP4.
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.

sb is often taken by sb to do sth on sundays.
My dad often takes me to watch a film on Sundays.
I am often taken by my dad to watch a film on Sundays.

例如,This gift is given to me by my mother、这件礼物是被我妈妈送给我的,意译便是这件礼物是妈妈给我的.我觉得还是在实际句子中体味比较容易理解.多做被动语态的题目,语感自然就出来了.

locate sth in swhere
所以一般表示某物位于哪里(这里的某事就是上面的sth )
就要用被动

被动语态八注意 1．我们知道,主动语态变为被动语态时,通常将主动语态中的宾语变为被动语态的主语；主动语态的主语变为由介词by引导的宾语；谓语动词变为被动语态“be 过去分词”形式,例如： Everyonelikestheinterestingfilm.(主动语态)→Theinterestingfilmislikedbyeveryone.(被动语态) Theyusedknivestocutthings.(主动语态)→Knivesareusedtocutthings.(被动语态) 但是,并非所有由“be 过去分词”构成的形式就是被动语态.有时过去分词已经变为形容词,表示一种状态.试比较： MybrotherisveryinterestedinEnglish.我哥哥对英语非常感兴趣.（状态） MybrotherwasinterestedbywhatItoldhim.我告诉他的话让我哥哥非常感兴趣.（动态） 2．在被动语态中谓语动词一定是及物动词,也就是说必须跟宾语的动词.如： Wecanmakemetalsintodifferentshapes.(主动语态)→Metalscanbemadeintodifferentshapes.(被动语态) 在主动语态中make是及物动词,其动作的承受者即宾语是metals. 但是,并非所有的及物动词都有被动语态.比如,表示静态的动词（have、belongto）、宾语是反身代词或相互代词等.例如： Hehasanicehouse.他有一所漂亮的房子. Wemusthelpeachother.我们应该互相帮助. 3．主动语态中的主语在变为被动语态时通常变为由介词by的引出的宾语.如： Theyhavealreadycutdownthetrees.→Thetreeshavealreadybeencutdownbythem.那些树木已经被他们砍光. 如果谓语动词是know,在变为被动语态时,原来的主语变为由to引出的宾语.如： Maypeopleknowhimverywell.→Heiswellknowntomanypeople.很多人都非常了解他. 注意：我们之所以用被动语态是因为我们不清楚动作的执行者、或没有必要指出动词的执行者等.因此很多被动语态没有由by引出的宾语.如： Peoplemaylosetheirlivesandhomesortheymaybeinjuredbadlyinafire.在大火中人们可能失去性命和家园,要不就是严重烧伤. Itisusedforprotectingthefiremanfromsmoke.它用来保护消防人员以避免吸进烟雾. 4．在主动语态变为被动语态时,时态一般应保持一致.如： Wewillbuildmorefactoriesinmyhometown.→Morefactorieswillbebuiltinmyhometown.我们家乡将要建起更多的工厂. 为此,我们必须记住以下某些时态的被动结构： do（es）→is/am/aredonedid→was/weredone have/hasdone→have/hasbeendonewilldo→willbedone bedoing→bebeingdone 5．某些动词可以跟双宾语如give、pass、bring、write；buy、make等,在变为被动语态时如果直接宾语变为被动语态中的主语,则间接宾语通常由介词to、for引出.例如： Mysistergavemeanicewatchformybirthday.→Anicewatchwasgiventomebymysisterformybirthday.我过生日时收到了姐姐的一块手表. Theyhaveboughtusmanybooks.→Manybookshavebeenboughtforusbythem.很多书都是由他们给我们买的. 6．某些动词make、hear、see、watch等在主动语态中,其宾语补足语要求用不带to的不定式.但在变为被动语态时通常省略的不定式符号to必须恢复.如： Hemadeuscleantheclassroomafterschool.→Weweremadetocleantheclassroomafterschool.我们被迫在放学后打扫教室. Isawhimcomeintotheroom.→Hewasseentocomeintotheroom.人们看见他进了屋子. 7．在主动语态中如果谓语动词是含有介词或副词的短语动词,变为被动语态时不能丢掉该介词或副词.如： Theymusttakegoodcareofthechildren.→Thechildrenmustbetakengoodcareof.孩子们必须小心照看. 8．英语中某些动词如sell、lock、draw、start等在否定句、进行时或用在某些形容词、副词前可以表示被动意义.如： Thiskindofbookssellswell.这种书畅销. Thedoorwon’tlock.门锁锁不上.
1.定义：被动语态,即不知道动作执行者或强调动作承受者的一种语态.例如中文常说：我被他打,这就是一种被动.但有时由于句子结构上的需要也要用被动,例如Itisnotunusualforworkersinthatregiontobepaidmorethanamonthit在句中作形式主语.而不定式tobepaidmorethanamonth是句子的逻辑主语.结合选项全句的意思是：“那个地方的工人一个多月后才得到工资是常有的事”. 2.构成：be pastparticiple(过去分词)(简称P.P.)（ by 动作执行者）（过去分词的概念见上课） 3.当主动语态要被改成被动的时候,我们把原句的宾语提前,作为改句的主语,主语后置,作为宾语.因此有一点要注意,不及物动词由于不加宾语,没有被动形式,但不及物动词如果与某些介词构成介词短语,可以用被动.例如Thefirehadbeenputoutbeforethefiremanarrived.Put是不即物动词,但putout是及物动词 4.应用到各种时态和句型如下： ①一般式（一般现在,一般过去,一般将来）：am,is,are,was,were,isgoingtobe,willbe done.ie.Onceenvironmentaldamageisdone,ittakesmanyyearsforthesystemtorecover.本句的意思是：“环境一旦遭到破坏,需要多年时间才能恢复过来.”do作为及物动词有“引起,产生”的含义,dodamage的意思是“造成破坏”.主语damage是及物动词do的动作对象,谓语应当用被动语态.同样的,还有,Iwillmendthemachine.相当于Themachinewillbemended（byme）. ②进行时（现在进行、过去进行、将来进行）：be being P.P.ie.Theclassroomisbeingcleaned. ③完成时（现在完成、过去完成、将来完成）：have/hasbeen P.P.：例如Themachinewillhavebeenrepairedby3o’clockthisafternoon.再如：Myhomeworkhasbeenfinished. ④其他时态依词类推,可得到结果. ⑤情态动词的被动语态：主语 情态动词 be动词 动词过去分词,例如Yourteethmustbebrushed. ⑥不定式的被动语态：tobedone例：Theno-showshavetobeconsideredwhendecidingtherateofoverbooking.（确定超过接待能力的预定时必须考虑预定了房间却来不了的客人.）
