基本结构：be +过去分词。要表示由某人做的，加by sb时态和人称要体现在be动词复上面。制比如：那块蛋糕被我吃了。the cake was eaten by me.(过去时） 会议将在两天后召开。the meeting will be held in two days. (将来时） 等等初学者百容易错的是不知道该用被动度形式。比如动词填空时，所给词填什么形式，要考虑是否与主语是被动关系。比如：this kind of computer _______(sell) in many countries. 这里电脑和卖的关系是被动，一般现在时，主语为单数，所以填is sold.被动语态难知点很多，一两道句说不清，说太多了也不可能马上记住。还是具体题目具体分析吧。 本回答由提问者推荐
被动语态：相当于汉语中copy的被字句。构成：S+be+P.P.+by+执行者什么时候用被百动语态，在不知道谁做度的这件事时，或者不重要时，就用被动语态。纯手写知 望采纳道 O(∩_∩)O~ 注释：P.P.为动词的过去分词。
初中英语被动语态一、被动语态概述语态是动词的一种形式，用以说明主语与谓语动词之间的关系。英语的语态共有两种：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。被动语态是动词的一种特殊形式，一般说来，只有需要动作对象的及物动词才有被动语态。汉语往往用"被"、"受"、"给"等词来表示被动意义。如：He opened the door.他打开了这扇门。（主动语态）The door was opened.这扇门被打开了。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。被动语态的时态变化只改变be的形式，过去分词部分不变。疑问式和否定式的变化也如此。1、被动语态的时态较常见的八种，现以动词clean为例列表说明： 2、被动语态的句式变化：以一般现在时和动词invite为例，列表说明被动语态的句式变化： 3、含有情态动词的被动语态 情态动词的被动语态结构为：情态动词+be+过去分词；其时态及句型的变化仅由情态动词完成，"be+过去分词"部分不变。如： Tables can be made of stone.桌子可由石头制造。 Tables could be made of stone at that time. 那时桌子可由石头制造。（一般过去时） Can tables be made of stone? 桌子能用石头制造吗？（疑问句） 三、主动语态变为被动语态 转换图示： 1、主动语态变为被动语态的步骤： （1）将主动句的宾语变为主语： 注意：如果主动句的宾语是代词，需将其由宾格变为主格。如： Tom killed him. → He was killed by Tom.I hit him.(主) → He was hit by me. (被) （2）将动词改为"be+过去分词"。 注意： They held a meeting yesterday. → A meeting was held by them yesterday. 他们昨天开会了。 （3）将主动句的主语改为by的宾语，放在谓语动词后。 注意：如果原主语是代词，则应由主格变为宾格。 He sang a song. → A song was sung byhim. 2、主动语态变为被动语态的注意事项： 含有双宾语，即直接宾语（常指事物）和间接宾语（常指人）的句子，每个宾语都可变为被动语态的主语，即其被动语态有两种形式。但多以间接宾语作主语。Jack told us the truth.杰克告诉了我们真相。We were told the truth by Jack. Jack told the truth to us.The truth was told to us by Jack. Tom gave me a pen.(主)I was given a pen by Tom.(被) Tom gave a pen to me. （主）A pen was given to me by Tom.(被) write, make, bring等的被动语态则只能以直接宾语（表物）作主语。You brought me a big cake. (主)A big cake was brought to me by you. (被) She wrote me a letter.(主)A letter was written to me by her.(被) 四．注意事项：1. 主动语态变为被动语态，句子的时态保持不变。I will give him a pen.(主)He will be given a pen by me.(被)我将给他一支笔。 2. 在感官动词或使役动词后作补语的动词，在被动语态中用不定式。1）I heard you talk with Peter. (主)我听到你和彼得谈话。You were heard to talk with Peter. (被)2）I saw her come out of the classroom.(主)我看见她出了教室。She was seen to come out of the classroom by me.(被)3）make/let sb do sth Sb be made/let to do sth 3. 主动语态中如用people, somebody等作主语，被动语态中可省略宾语。People eat watermelons in the summer.(主)Watermelons are eaten in the summer.(被)在夏天吃西瓜。 4. 否定句的被动语态中，not放在第一个助动词后。1) You should not blame me. (主)你不应该责怪我。I should not be blamed by you. (被)2) You should not write this letter.(主)你不应该写这封信。This letter should not be written by you.(被) 5. 疑问句的被动语态中，用BE代替DO。1) Does she drive this car?(主)Is this car driven by her?(被)2) What shall we do next?(主)What will be done by us next?(被) 6. 祈使句的被动语态形式为：let+宾语+be+过去分词。Open the door please.(主)Let the door be opened please.(被) 7. 主动语态中有复合人称代名词时，被动语态的形式为:主动语态的主语+BE+过去分词。Tom hurt himself. (主)Tom was hurt. (被) 8. 下列动词（词组）没有被动式：1）系动词：以主动形式表示被动之意常见的系动词有：① be动词 ② ……起来（7个）：look, sound, smell, taste, feel , seem, appear e.g. She seems/appears happy. It smells terrible. ③ (逐渐)变得/变成：become, grow, get, turn, come, go e.g. His wish has come true. People often went hungry in the old days. The tree is growing tall. ④ 保持：keep, stay e.g. We must keep quiet in the reading room.2）happen, take place, break out（爆发）,belong to ,cost, take3）不及物动词sell, wash, read , write, open, close, shut, lock, wear等，常用主动形式表示被动意义。 1、An accident was happened yesterday.（×）昨天发生了一起事故。 An accident happened yesterday. 2、The flower smells sweet.这花闻起来很香。 3、The watch looks good.这表看起来很好。 4、This book sells well.这本书畅销。5、The kind of cloth washes well. 这种布很容易洗。6、The article reads well. 这篇文章读起来很好。 7、The supermarket opens at 8:00 in the morning. 超市在早上八点钟营业。8、The door won’t close/shut. 这门关不上。 9、The door locks easily. 这门容易锁。7a686964616f31333330356236 10、This material wears well (won’t wear). 这种材料耐久（不耐久） 六、各种时态的被动语态举例（以动词do为例） 1．一般现在时（am/ is/ are +done） English is spoken by lots of people in the world. 世界上的许多人都说英语。 Class meeting is held every Thursday.每周四都举行班会。 The classroom is cleaned by the students every day. 学生们每天都打扫教室。 2．一般过去时(was/ were +done) The cup was broken by the boy. 杯子被那个男孩打碎了。 He was saved at last. 他最终获救了。 My bike was stolen. 我的自行车被偷了。 3．一般将来时与过去将来时(will/ shall be +done; would/should be +done) A speech will be given this afternoon.今天下午有一个演讲。 A new road will be built next year. 明年要修一条新马路。 I thought thousands of people would be helped. 我认为将有数千人得到帮助。 4．现在进行时与过去进行时(am/ is/ are being +done; was/ were being +done) The machine was being repaired at this time yesterday. 昨天这时，机器正在被修理。 The problem is being discussed now. 问题正在被讨论。 A bus is being pushed by the passengers. 路人正在推一辆公共汽车。 5．现在完成时(have/ has been + done) Two hundred trees have been planted by now. 到现在为止，已经种了二百棵树了。 The book has been read many times by me. 这本书已经被我读了许多遍了。 6．过去完成时(had been+done) They said they had been invited to the party. 他们说已经被邀请参加晚会了。 She found the house had been destroyed by the storm. 她发现房子已经被暴风雨摧毁。 He had been tortured by the illness for many years before he died. 他在去世前已经被疾病折磨很多年了。
be动词百+V的过去分词 情态动词后度面＋be＋过去问分词答(pp)1.should be +pp2.must be +pp3.can be +pp另外have/ has/hadhave/has/had +been +pp还有进行时态is/are +being +pp还有过去式的was+being +pp(过去进版行时）had +been +pp(过去完成时）was +pp（一般过去时权）
1-1 当句子的主语为动作的承受者即受动者，动词用被动语态。Eg. John helped Peter. （John是动作的施行者，而Peter是动作的承受者即承受者。） Peter was helped by John. （Peter是句子的主语，而且是动作的承受者，所以用被动语态。）1-2 被动语态的构成：be + 动词的过去分词2. 特别提醒：被动语态的时态和人称的变动都是由动词be作改变的，不论发生什么改变，动词的过去分词(v+ed或不规则的分词) 都不改变。时态用的助动词和人称代词由被动语态句子中的主语，即动作的承受者，所决定。2-1 Eg. He cleans the room everyday. The room is cleaned (by him) everyday. (一般现在时的被动语态构成: is / am / are + 动词的过去分词)2-2 Eg. They have brought many toys since last week. Many toys have been brought (by them) since last week. (现在完成时的被动语态构成：has/have + been + 动词过去分词。)2-3 Eg. They are meeting the foreigners at the gate. The foreigners are being met (by them) at the gate. (现在进行时的被动语态构成：is/ are/ am + being + 动词过去分词)2-4 Eg. They will build some new buildings next year. Some new buildings will be built (by them) next year. They are going to draw a new picture tomorrow. A new picture is going to be drawn tomorrow.(一般将来时被动语态构成：will + be +动词过去分词, 或is/am/are going to +be + 动词过去分词)2-5 Eg. Father has been painting the room all morning. The room has been being painted (by father) all morning.(仅作了解：现在完成进行时的被动语态：has/ have + been+ being + 动词过去分词)2-6 Eg. They wrote the book last year. The book was written (by them) last year. （一般过去时的被动语态构成：was/ were+动词过去分词）2-7 Eg. The children had broken the window when the teacher arrived. The windows had been broken (by the children) when the teacher arrived. (过去完成时被动语态构成had + been + 动词过去分词。)2-8 Eg. She was reading the book at 8:00 last night. The book was being read at 8:00 last night. (过去进行时被动语态构成：was/ were being + 动词过去分词)2-9 Eg. They said they would cook some food. They said some food would be cooked. They said he was going to buy a new house. They said a new house was going to be bought.(过去将来时被动语态构成：would +动词过去分词，或：was/were going to be + 动词分词)2-10 Eg. He must finish the work in two days. The work must be finished in two days. (情态动词被动语态：must/have to/had better/ should/can/could/may/might/need to + be +动词分词) 3． 间接引语中的被动语态：3-1 引述动词是一般现在时的时候，引语的人称根据引述动词前面的主语而作调整，但时态不变。Eg. He often says, “ I was chosen to take part in the exam when I was twelve.” He often says he was chosen to take part in the exam when he was twelve. （人称由引述动词says前面的主语he 决定，但引语的时态不变。）3-2 引述动词为过去时态，引语部分的时态和人陈都按照引述部分进行改变。Eg. He said, “ My father has been hit by a car.”He said his father had been hit by a car. (引语部分的时态和人称都发生了改变。)3-3 从上文可看出：引述动词是过去时态时，被动语态形式的引语改动规则与主动语态形式的引语的改动规则一样，但无论如何，只要是被动语态，它的动词的过去分词总是不改的。）4．几种7a6431333264643135特殊的情况需要特别注意：4-1. 带介词的双宾语可以有两种改法：eg. They gave him an apple. He was given an apple. An apple was given to him. (双宾语中当直接宾语apple 作被动语态句子的主语时，要记得写上介词to。)4-1-1这样的动词有：buy/make/cook sth for sb 或：show/bring/give/take/ send/write/… to sb.4-2. 多词动词的被动语态：eg. She looked after his children. His children were looked after (by her).4-2-1这样的动词有：look after, look into, talk about, set up, put off, bring about, do away with, look forward to, take good care of 等等词。4-3 It is/was/has been said/reported/known + that + 从句4-4 有些动词在主动语态里不带to，但改为被动语态时要还原tomake/see/have/hear/let sb do sth sb be made/seen/heard/let to do sth eg. The boss made the workers work for a long time. The workers were made to work for a long time (by the boss).4-5 有些动词在主动语态中带sb doing sth, 改为被动语态时仍用doing stheg. I heard him singing in his room. He was heard singing in his room.4-6 特别区分：当句子中出现suddenly, 具体的时间时，用see/hear sb doing sth的形式当句中出现often, always, sometimes, 或不具体的时间时，用see/hear sb do sth的形式。Eg. 1) I often hear him sing in his room. 2) Yesterday I saw him cross the road. 3) Suddenly they heard someone crying in the forest.4-7 不及物动词没有被动语态：happen, take place, begin, become, go, comeeg.

现在完成时 现在进行时 一般过去时 一般将来时 过去将来时 过去进行时 过去完成时 一般现在时I)被动语态的概念 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：主动语态和被动语态People .被动语态表示主语是谓语动作的承受者，. (II)被动语态的构成 被动语态的形式是由“助动词be动词的过去分词”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。各种时态的被动语态形式如下： 1. 注：Get＋过去分词也可以构成被动语态，用这种结构的句子侧重于动7a64e4b893e5b19e31333332623334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。 )被动语态的几种句型 1.将主动语态中的宾语转换成被动语态的主语。 2.将主动语态中的动词改为“be+V(p.p)” 3.原来主动语态中的主语，如果需要，放在by后面以它的宾格形式出现，如没必要，可以省略。4.主动语态中的其他句子成分不变。 由于主动语态结构的不同，因而转换成被动语态的方式也各有不同，现分类说明如下： a.由及物动词形成的被动语态： (1)S+V+O 主语+动词+宾语语法学习纲要由江苏省靖江高级中学外语组为英语猫网站编写 People grow rice in the south. Rice is grown in the south. 注：带有宾语从句的句子转换成被动语态时，需要将宾语从句变为主语从句，通常用形式主语来代替，而将主语从句后置。 They said that he would come back soon. It was said that he would come back soon.类似的还有： It is reported / believed /hoped /supposed that …… (2)S+V+O+C 主语+动词+宾语+宾补 We elected Li Ming monitor of our class. Li Ming was elected monitor of our class. 注：在主动结构中跟不带to的动词不定式作宾补变为被动结构时应加上to作主语补足语。 奴隶们被奴隶主强迫整日整夜工作。Slave-owners made slaves work all day and all night. Slaves were made to work all day and all night by slave-owners. (3)S+V+Oi+Od 主语+动词+间宾+直宾 语法学习纲要由江苏省靖江高级中学外语组为英语猫网站编写 昨天他给了我一件漂亮的生日卡。He gave me a beautiful birthday card yesterday. I was given a beautiful birthday card yesterday. A beautiful birthday card was given to me yesterday. 注：用直接宾语作被动语态的主语时，通常要在间接宾语前加上适当的介词。如：to, for, of等，以加强间接宾语的语气。 b.由动词短语形成的被动语态： 一般情况下，只有及物动词才能跟宾语，而不及物动词不能跟宾语，所以只有及物动词才有被动语态，不及物动词则没有被动语态。但有些不及物动词后面跟上介词或副词后，变成一个动词短语，相当于一个及物动词，就可以形成被动语态。 约翰打开了收音机。John turned on the radio. The radio was turned on. . 注：千万不要遗漏介词或副词。 c.祈使句的被动语态通常借助let句式 请把窗户关上。Please close the window. Let the window be closed. (IV)被动语态的使用时机 语法学习纲要由江苏省中学外语组为英语猫网站编写 被动语态的使用往往不是任意的，而是按照表达思想，描述事物的需要，通常在下列情况下使用被动语态。 1.不知道或不必说出动作的执行者。 这本书已被翻译成许多种语言。This book has been translated into many languages. 2.动作的对象是谈话的中心。 我们家乡将建一条新铁路。A new railway will be built in our hometown. 3.修辞的需要，为了使句子更加简练匀称： 他出现在舞台上受到了观众的热烈欢迎。He appeared on the stage and was warmly applauded by the audience. 被动语态便于论述客观事实，故常用于科技文章，新闻报道，书刊介绍及景物描写。 【特别提醒】 有些动词后跟不带to的不定式作宾语补足语，但改为被动结构后要加上“to”。例如 We heard him sing in his room just now. ---He was heard to sing in his room just now. 刚才听到他在房间中唱歌。 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 by my mother. 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.

这不是双宾语这是复合宾语 即宾语加宾补动词不定式作宾补时 在有的动词后面 不加to即不定式来作宾补下列词后省略to“三眼”“两耳”“一感觉”外加三个“小使役”“三眼”指see、 watch、 look at“两耳”指hear、 listen to“一感觉”指feel “小使役”指let 、make、 have在这些动词后的不定式作宾补to 要省去。例如： I saw him come . 我看见他来了。 I heard him sing . 我听见他唱歌了。 We felt the house shake 我们感到房子摇动。 Let him do it . 让他做7a686964616fe78988e69d8331333335343338吧。 I would have you know that I am ill . 我向要妮知道我病了。 They made the boy go to bed early . 他们让那男孩早早睡觉去。 注释 在动词find 、help 后不定式做宾补可带to 也可不带to 。 上述感觉动词与使役动词转换为被动结构时，其后的动词不定 式一般须带to 。 如：he was seen to come . 看见他来了。 The boy was let to go to bed early . 让这个男孩早点睡觉。也就是被动语态中 原来作宾补的不定式 变成了主补 不定式作主补必须带to所以你的例句1 I often see him play the piano after school. 改为被动语态答案是he is often seen to play the piano after school.2 They are often heard to sing songs by him in the next room. 改为主动语态答案是he often hears them sing songs in the next room.
see doing 表示看见正在做某事enter是个点动词，要么就进去了，要么就没进，走进办公室还用正在吗？时间极短的。
