2021年主动句变被动句
主动句变被动句 欧阳光明（2021.03.07） 被动语态由“be+done”构成。不同时态的被动语态的差异主要体现在助动词be的变化上，同时be还要在人称和数上与主语保持一致。 在将主动语态变为被动语态时，可按以下三个步骤： a.把主动语态的宾语变为被动语态的主语。 b.把谓语变成被动结构(be＋done) ，并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。 c.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。 在无须说明动作的执行者或只强调动作的承受者时，by短语可以 省略。例如： 1. We speak Chinese. →Chinese is spoken by us. 2. All the people laughed at him. →He was laughed at by all people. 3. They make the bikes in the factory. →The bikes are made by them in the factory. 含有双宾语的主动句改为被动句时，应将其中一个宾语改为被动结构的主语，另一个宾语仍保留在原处。一种情况是把间接宾语(指人)变为主语，直接宾语(指物)不变；另一种情况是把直接宾语(指物)变为主语，间接宾语(指人)不变，这时,间接宾语前通常加介词to，有时加for。例如： My father gave me a new book on my birthday. →I was given a new book (by my father) on my birthday. (间接宾语作了主
主动句变被动句
主动句变被动句 John helped Peter. ----- Peter was helped by John. 转换规则 1、主动句变被动句的实质是将主语和宾语的位置对调，动词由原来的形式变为be加上动 词的过去分词。如不需要突出动作的执行者，也可不要by-词组。 They punished the criminal. ----- The criminal was punished. 2．如果主动句带有情态助动词或半助动词，在变为被动句时，情态动词或半助动词保持不变，谓语动词由主动变为被动。 They should do the work at once. ----- The work should be done at once. They must have finished their work. ----- Their work must have been finished. He is likely to let you down. ------ You are likely to be let down. 3、如果主句是双宾语结构，变为被动句时刻有两种形式：一种是以间接宾语作主语；另 一种是以直接宾语作主语。 They offered him some assistance. ----- He was offered some assistance. ----- Some assistance was offered to him. Father gave me a watch. ----- I was given a watch. ----- A watch was given to me. 4、如果主句的结构带有宾语补足语，变被动的时候要将原来的宾语补语变为主语补语。We have painted the windows white. ----- The windows have been painted white. They elected Tom monitor of the class. ---- Tom was elected monitor of the class. 5、当主动句变为被动句时，有时用by-词组，有时不用。一般来说，当施动者为谁不太清 楚、不甚重要或不愿说出时，通常不用by词组。但有时为了强调施动者，则须用by 词组。 Hamlet was written by Shakespeare. Susan was cheated by David. 有时为了避免中途变更主语，不得不用被动句而把施动者置于by-词组中。 He arrived at London where he was met by his friend. Practice 1.They built this house in 1968. 2.People speak English almost all over the world. 3.No one has ever beaten him at once. 4.They use milk for making butter and cheese. 5.They are repairing my piano at the moment. 6. Somebody had cleaned my shoes. 7.He said they were starting a new system. 8.You can’t wash this dress; you must dry-clean it. 9.They will have to adopt a different attitude. 10.People mustn’t leave bicycles in the hall.
[精]主动语态变被动语态时所注意的问题
主动语态变被动语态时所注意的问题1. 把主动语态变为被动语态，其谓语动词的时态要与原句时态保持一致，其谓语动词的数要与新主语保持一致。 We have bought a new computer. A new computer has been bought. A new computer have been bought. （错误） 2. 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多 My uncle gave me a present on my birthday. I was given a present on my birthday. 如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说： A present was given to me yesterday. 注意：
1.一般在下列动词后，常在间接宾语前用介词to，如：bring, give, hand, lend, offer, pass, pay, promise, sell, show, take, teach, tell 等。 (1) The book was showed to the class. (2) My bike was lent to her. 2.一般在下列动词后，间接宾语前用介词for, 如：build, buy, cook, cut, choose, do, fetch, find, fix, get, keep, make, order, paint, play, sing 等。 (1) A new skirt was made for me. (2) The meat was cooked for us. (3) Some country music was played for us. 3. 由动词+ 介词或副词构成的短语动词，要把它们作为整体看，即把它们看成一个及物动词，介词或副词不可拆开或漏掉。这类动词有：不及物动词+ 介词，如: agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等。 The patient is being operated on. T he problem is solved. It needn't be talked about.

主动语态变被动语态的方法
主动语态变被动语态的方法 1. 基本方法 将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)： He stole our money.→Our money w as stolen by him. 【注】(1)若不强调动词执行者，被动语态中的by短语通常可以省略： The house was built in 1978. 这座房子是1978年建的。 (2)在转变语态时，要注意保持两种语态时态的一致性： The students will study the problem. →The problem will be studied by the students. A friend of ours is repairing the roof. →The roof is being repaired by a friend of ours. 2. 双宾动词的被动语态 双宾动词即指带双宾语的动词，它们在变为被动语态时，有以下两种情形值得注意： (1)有些双宾动词(如award, buy, give, leave, lend, offer, pay, show, teach, tell等)在变为被动语态时，既可把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)，也可把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to 或for引起的状语(到底用to还是for，与所搭配的动词有关)。比较： He gave her some money. 他给她一些钱。 → She was given some money. / Some money was given to him. He bought her a watch. 他给她买了一快表。 → A watch was bought for her. / She was bought a watch. (2)有些双宾动词(如bring, do, make, pass, sell, send, sing, write等)通常用直接宾语(指事物)作被动语态的主语，而将间接宾语用作保留宾语(其前根据情况用介词to或for)： Father made me a doll. → A doll was made for me. He wrote her a letter. → A letter was written to her. (3)有些双宾动词(如answer, deny, envy, refuse, save, spare等)通常用间接宾语(指人)作被动语态的主语，而将直接宾语用作保留宾语： He answered me that question. → I was answered that question by him.

主动句变为被动句所遵循的4个步骤
主动句变为被动句所遵循的4个步骤： 1、把原主动句中的宾语变为被动句的主语 2、把动词变为被动形式即be +过去分词，并注意其人称和数随主语的变化，而动词的时态则保持不变。 3、原主动句的主语如需要则放在by后面以它的宾格形式出现（注代词的宾格），如不需要则可省略。 4、其它的成分（定语、状语）不变。情态动词的被动语态一、理解含情态动词的被动语态的概念含情态动词的被动语态说明某个被动性动作所反映出的感情和态度。初中阶段可用于被动语态的情态动词有“can、may、must、need、should”等，分别表示“能够被……”，“可以被……”，“必须被……”，“需要被……“，应该被……”等。二、掌握含情态动词的被动语态的不同句式的变换方法含情态动词的被动语态的疑问句、否定句的变化均借助于情态动词完成。（一）一般疑问句直接将陈述句被动语态中的情态动词提前。如：Must this work be done at once？这项工作必须立即完成吗？Should your homework be finished before six？你的家庭作业应在六点前完成吗？（二）特殊疑问句由疑问词加上一般疑问句被动语态构成。如：When must this work be done？这工作必须在什么时候完成？Where can the lost book be found？这本失踪的书能在什么地方被找到？（三）反意疑问句借助情态动词构成附加疑问部分。如：This bridge can be built next year，can't it？这座桥明年能建成，是吗？This book shouldn't be taken out of the library，should it？这本书不应被带出图书馆，是吗？（四）否定句在情态动词后面加上“not”或“never”即可，但“must”表“必要”时否定式为“needn't”。如：This work needn't be done at once．这项工作没必要立即做。This dustbin shouldn't be put here．这个垃圾箱不应放在这儿。三、含情态动词的被动语态的一般疑问句的回答含情态动词的被动语态的一般疑问句的回答应保留原情态动词，但“must”表“必须”时，其否定回答应用“needn't”、“need”表“必要”时，其肯定回答应用“must”。如：—Should my exercises be finished today？我的作业应在今天完成吗？—Yes，they should．是的，应在今天完成。（No，they shouldn't．不，不应在今天完成。）—Must his exercise book be handed in at once？他的练习本必须立即上交吗？—Yes，it must．是的，必须立即上交。（No，it needn't．不，不必立即上交。）—Need he be operated on at once？他必须立即手术吗？—Yes，he must．是的，他必须。（No，he needn't．不，他不必。） 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 +V.过去分词，be有人称、时、数变。完成时态have（has）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。 1.一般现在时is\am\are+P.P （过去分词） 2.一般过去时was\were+P.P 3.一般将来时will be+P.P 4.现在进行时is\am\are+being（固定不变）+P.P 5.过去进行时was\were+being（固定不变）+P.P 6.现在完成时have\has been+P.P 7.过去完成时had been+P.P

(完整版)主动语态变被动语态的几种类型
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

主动语态变被动语态的方法 一、主动语态和被动语态概说 英语的语态分主动语态和被动语态，主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。被动语态由“助动词be+过去分词”构成：Everybodylikeshim.大家都喜欢他。(主动语态) Heislikedbyeverybody.他受到大家的喜欢。(被动语态)二、主动语态变被动语态的方法 1.主动语态变被动语态的基本方法 将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)：Hebrokethecup.→Thecupwasbrokenbyhim. 【注意】若不强调动词执行者，被动语态中的by短语通常可以省略：Hewasbornin1986.他生于1986年。 Whatisthisflowercalled这种花叫什么花 2.双宾动词的被动语态 双宾动词即指带双宾语的动词，它们在变为被动语态时，通常是把间接宾语(指人)变为被动语态的主语，而把直接宾语(指事物)保留下来(称为保留宾语)：Heansweredmethatquestion.→Iwasansweredt hatquestionbyhim. 有的动词则通常把直接宾语(指事物)变为被动语态的主语，而把间接宾语改为介词to或for引起的状语(到底用to还是for，与所搭配的动词有关)：Hewroteheraletter.→Aletterwaswrittentoher.(与动词write搭配用介词to)Shemadehimanewcoat.→Anewcoatwasmadeforhim.(与动词make搭配用介词for) 有时以上两种方式均可用： Hegavehersomemoney.他给她一些钱。→Shewasg ivensomemoney./. 他给她买了一块表。→Awatchwasboughtforher./.被动语态的时态 被动语态的时态由被动结构“be+过去分词”中的动词be来体现，其基本结构和用法如下：
被动语态复习
【被动语态】 （一）语态：英语的语态是通过动词形式的变化表现出来的。 主动语态表示主语是动作的执行者。 例如：Many people speak Chinese.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。 例如：Chinese is spoken by many people. 主语English是动词speak的承受者。 （二）被动语态的构成 人称、数和时态的变化是通过be的变化表现出来的。 一般现在时：am／is／are＋V-过分一般过去时：was／were＋V-过分 一般将来时：will／shall be＋V-过分过去将来时：would be + V-过分 现在进行时：am／is／are being＋V-过分过去进行时：was/were being＋V-过分 现在完成时：have／has been＋V-过分过去完成时：had been + V-过分 （三）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。可省略。例如：All the people laughed at him. →He was laughed at by all people.
