被动语态的结构及用法

Step 1 Warm-up: Review 复习

一、Review the past participle forms of the verbs

1、规则动词过去分词的构成:

(1)一般情况+ed 如worked;以不发音的e结尾,直接+d 如liked

(2)以“辅音字母+y”,y →i+ed 如study →studied

(3)以重读闭音节结尾,词尾仅一个辅音字母,双写词尾辅音字母+ed

如stopped,planned

2、特殊变化:课本附录

Step 2 Presentation:呈现

一、语态概述:略讲

1、英语的语态是通过动词形式的变化表现出来的,分为主动语态与被动语态两种。

2、主动语态,即主语是动作的执行者。Eg. We clean the classroom.

3、被动语态,即主语是动作的承受者。Eg. The classroom is cleaned by us.

二、被动语态的构成:略

被动语态的基本构成是“助动词be+及物动词的过去分词+(by)”。be本身无词义,但有时态、人称和数的变化。by通常紧跟在被动句谓语动词之后,有时也可省。

1、现在:

(1)一般现在时am/is/are + done

(2)现在进行时am/is/are + being done

(3)现在完成时have/has + been done

2、过去:

(1)一般过去时was/were + done

(2)过去进行时was/were + being done

3、将来:一般将来时shall/will + be done

三、被动语态句式:略

(1)肯定:主语+be+过去分词+(by) The cars are made by them.

(2)否定:主语+be+not+过去分词+(by)The cars are not made by them.

(3)一般疑问句:Be+主语+过去分词+(by) Are the cars made by them?

(4)含有情态动词的被动语态:主语+情态动词+(not)+be<原形>+过去分词+(by)

四、被动语态的用法:

1、强调动作的承受者eg. Her bike is stolen.

2、淡化动作的执行者(没有说明、没必要指出、不知道)

Eg. This coat is made of cotton.这件大衣是棉制的。

3、动作的承受者是谈话的中心eg. The picture was drawn by a boy under eight.

Step 3 Consolidation:巩固

五、主动与被动的转换:时态不变

A.主动中的宾语→被动语态的主语

B.谓语变成被动结构(be+过去分词)

C.主动中的主语→被动语态的宾语(介词by之后),主格→宾格

Eg. He cut down a tree.→A tree was cut down by him.

1、S+V+O

(1)主动句为带no的否定句,被动句常用no,neither,never等

Eg. No one has ever beaten her at tennis.→She has never been beaten at tennis.

(2)主动句为带any构成不定代词的否定句,被动句常用no

Eg. We didn't notice anything special in his work.

→Nothing special was noticed in his work.

2、S+V+O1+O2

(1)主动句的间接宾语/直接宾语→被动句的主语

Eg. They gave the children many good books.

→The children were given many good books.

Many good books were given to the children.

(2)只能主动句的直接宾语→被动句的主语

Eg. She wrote Jim a letter.→A letter was written to Jim.

(3)宾语从句一般不可作为被动句的主语

Eg. She told me when the film started. →I was told when the film started.

六、被动语态的注意事项:

1、by短语省略的几种情况:

(1)无法确定动作执行者eg. The Great Wall was built thousands years ago.(2)泛指动作执行者eg. Children should be given a good living.

(3)不愿说出动作执行者

(4)前后文对执行者已有暗示eg. Your homework should be handed in early tomorrow.

2、主、被动转化,被保留的间接宾语前还原介词to\for\of (give, send, take, bring, get等)

3、在被动语态中,感官动词和使役动词后面的不定式要带to (听hear, 观see/watch, 使make, 让let, 帮help)

4、没有被动语态的词:happen, rise, fit, turn, taste, sound, smell等

Step 4 Practice:练习

1.More and more foreigners speak Chinese in the world now.(改为被动语态)

2.Today Chinese _______(teach) in many schools around the world.

3.Rice is grown in the south by them.(改为主动句)

portrayed _____.

A had produced

B have been produced

C would have produced

D had been produced

板书设计被动语态的构成:

被动语态的基本构成是“助动词be+及物动词的过去分词+(by)”。be本身无词义,但有时态、人称和数的变化。by通常紧跟在被动句谓语动词之后,有时也可省。

1、现在:

(1)一般现在时am/is/are + done

(2)现在进行时am/is/are + being done

(3)现在完成时have/has + been done

2、过去:

(1)一般过去时was/were + done

(2)过去进行时was/were + being done

3、将来:一般将来时shall/will + be done

被动语态句式:

(1)肯定:主语+be+过去分词+(by) The cars are made by them.

(2)否定:主语+be+not+过去分词+(by)The cars are not made by them.

(3)一般疑问句:Be+主语+过去分词+(by) Are the cars made by them?

教学反思

被动语态基本构成

被动语态基本构成: 主语+be+动词过去分词 1. Calves are easily bound and slaughtered,Never knowing the reason why ( 一般现在时) 牛儿任人捆缚宰割,从来不知原因为何? Y ou must finish your work immediately. Y our work must be finished immediately. 2. I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. (一般将来时) 我梦想有一天,我的四个孩子将生活在一个不是以肤色的深浅,而是以品格的优劣作为评判标准的国家里。 3. If a good cook could cook good cookies, good cookies could be cooked by a good cook.. Y esterday my father beat me.

Should old acquaintance be forgot and never brought to mind Should old acquaintance be forgot and days of auld lang syne 怎能忘记,旧日朋友,心中能不怀想。 旧日朋友,岂能相忘,友谊地久天长 被动语态 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,

被动语态的几种特殊用法

被动语态的几种特殊用法(1)主动形式表示被动意义 1)常见的这类动词有:“act,add up,clean,compare,count,cook,draw,fill,iron,keep,let,look,make up,milk,kill,open,photograph,prove,read,sell,smoke,spoil”等。 The window won't open.(这扇窗户打不开。) The cow milks well.(这头牛出奶率很高。) Damp wood will not fire.(湿木不易燃烧。) She doesn't photograph well.(她不上相。) His judgment proved wrong.(他的判断是错的。) The banana peels easily.(香蕉皮剥起来很容易。) Flies kill easily in autumn.(秋天苍蝇容易死亡。) It turned out fine that day.(结果那天天气很好。) How did his coat catch on a nail?

翻译的基本技巧 被动语态的翻译

翻译的基本技巧——语态转换译法 语态转换译法 1 顺译法 顺译成被动句 顺译成主动句 2 倒译法 把by后的宾语倒译成汉语的主语 把其他介词后的宾语倒译成汉语的主语 倒译成汉语的无主句 3 分译法 一、顺译法 既保留原文的主语,又要使译文主要成分的顺序和原文大体一致的翻译方法就叫顺译法。 1 顺译法 (Translation in Original Order) 1. 1 顺译成被动句 A.译成“被”字 所谓“被”字句,就是在汉语的动词前面加上一个“被”字来表示被动的句子。主要表示这个动作不利于受事者或这个情况有点特殊,或者出乎意料。加上“被”字以引起读者的注意并表示“被”这一动作动作接受者(受事者)是不乐意或不情愿接受的。 例1:Vitamin C is destroyed when it is overheated. 【译文】维生素C受热过度就会被破坏。 例2:Once the flower has been pollinated and fertilized, the plant provides the newly formed seeds with a reserve of food materials, which will be needed when they themselves germinate. 【译文】花一旦被授了粉并受了精,植株就会对新生种子提供养料贮藏,以备种子未来发芽之需。例3:She thought all was fair and legal, and never dreamt she was going to be entrapped into a feigned union with a defrauded wretched, already bound to a bad, mad, and imbruted partner! (Charlotte Bront?: Jane Eyre) 【译文】她以为一切都是公正合法的,做梦也没想到过自己竟会被诱入欺诈婚姻的圈套,跟一个骗子、疯子、十足的坏蛋缔结姻缘。 B. 译成“挨”字句 “挨”仅用于翻译该动作是对动作接受者(受事者)不利或不好的句子。 例1:The boy was criticized yesterday. 【译文】这孩子昨天挨了一顿批评。 例2:I was caught in the downpour. 【译文】我在大雨中挨浇了。 C. 译成“给”字句

被动语态讲解与练习题

被动语态Passive Voice 一、被动语态的构成 动词语态是动词的一种特殊形式,表示句中主语和谓语动词之间的关系。英语的语态有两种: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或行为的对象。谓语动词为主动语态的叫主动句,为被动语态的叫被动句。 1.被动语态的基本构成形式 过去将来时:should/would be done was\were going to be done was\were about to be done was\were to be to done 过去将来完成时:should/would have been done 2. 含情态动词的被动语态 情态动词+be+过去分词 练习: 1) Visitors ___________ (request) not to touch the exhibits. 2) All the preparations for the task_______________(complete), and we're ready to start. 3) Look, a new cinema _____________(build) here now. 4) I _____________ (give) ten minutes to decide whether I should reject the offer. 5)By the end of last year, another new gymnasium ______________(complete) in Beijing. 6) A meeting ___________________(hold) when I was there. 7) Hundreds of job_____________ (lose) if the factory closes.

强烈推荐,有经典例句的被动语态的用法

一、被动语态的用法: 1、不知道或没有必要指出谁是动作的执行者时。 The bridge was built last year.这座桥是去年建造的。 He was elected chairman.他被选为主席。 2、当更加强调动作的承受者时。此时动作的执行者由by引导置于谓语动词之后,不需要时可以省略。 The room hasn't been cleaned yet.房间还没有打扫。 The tiger was killed by him.老虎被他杀死了。 3、当动作的执行者不是人时,多用被动语态。如: The window was blown by wind.窗户被风吹开了。 The whole village has been washed away by the flood.整个村庄都被洪水冲走了。 4、表示客观的说明常用"It is + 过去分词."句型。 It is said that Lucy has gone abroad.据说露茜已经出国了。 It is believed that he is a spy. (=He is believed to be a spy.)大家相信他是个间谍。 其它常见的"It is + 过去分词+ that"句型还有 It is reported that…据报道 It is said that…据说 It is believed that…大家相信 It is suggested that…有人建议 二、主动语态变为被动语态 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. (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)将主动语态的主语改为be…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 by him. 2、主动语态变为被动语态的注意事项: (1)主动句中的主语如果是people, we, you, they, somebody等含糊地表示"人们"、"大家"的单词,变为主动句时,通常删去"by…",但原主语被强调者除外。如:

语态篇——常见与不常见的被动 [提问]在下面这个句子中,那些部分为被动语态“I had not originally been scheduled to work this day but I was extremely pleased when I was asked to help out at the last minute, for it would be one of the most memorable days of the games. (Experiencing English Integrated Book Page120)” 答:要分析上面这个句子,并划出相应的被动语态部分,首先要清楚地了解什么是被动语态和被动语态的结构。 在学中,语态是针对动词而言的一种形式,描述句子中和参与此动作的之间关系。语态分为主动Active Voice和被动Passive Voice两种。当主语是动作的发起者(或之一)时,称为主动语态;如果主语为动作的承受者时,称为被动语态。例如:“猫吃老鼠。”这句话是主动语态;而“老鼠被猫吃。”则是被动语态。 一点意见,我觉得这些语法太简单了 被动语态强调动作的对象或动作本身,句中主语是动作的受动者。分析句子时找到主语和谓语动词,如果主语并非主动行为,而是接受动作,是动作指向的对象,那么该句就是被动句。被动语态的基本构成为: be动词+及物动词过去分词。其中be动词随着句子的不同时态发生相应变化,并要注意随主语人称、单复数变化而使用正确形式。 1)一般现在时:am/is/are+V-ed 2)一般过去时:was/were+V-ed 3)一般将来时:will/shall be+V-ed 4)现在进行时:am/is/are being+V-ed 5)过去进行时:was / were being + V-ed 6)现在完成时:have/has been+V-ed

被动语态的用法大全

语态是动词的一种形式,它表示主语和谓语的关系。语态有两种:主动语态和被动语态。如果主语是动作的执行者,或者是说动作是由主语完成的,要用主动语态;如果主语是动作的承受者,或者是说动作不是由主语而是由其他人完成的,则用被动语态。 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,英语却应该用被动态。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。还有些特殊现象,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 +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 语法结构 1.if结构(非真实条件句——表示的是假设的或实际可能性不大的情况) 与..事实相反If从句主句 过去Had done Would* have done
