含情态动词的被动语态形式:

注意:

1.在被动句中,经常用介词by引出动作的发出者。

2.当主动句句子结构为主+谓+间宾+直宾时,变成被动句,主语为直接宾语时,在间接宾语前面加上介词to/for。

My uncle bought me a new computer.

→A new computer was bought for me by my uncle.

They were offered headsets and gloves in the cinema.

Headsets and gloves were offered to them in the cinema.

3.有些动词经常以被动语态的形式出现,通常把其看成形容词。

这些词有:

be bored with be born in/on

be disappointed at/by be puzzled by

be pleased by/with be surprised at/by

be hidden in be devoted to

be buried/absorbed in be employed/occupied in

be impressed by be dressed in be lost

4.在主动句中,“一感二听三让四看”即使役动词let/have/make以及感官动词feel, hear/listen to, see/watch/observe/notice 等后面接动词不定式作宾语补足语时不带to,但变成被动句时需要加上to。

5.get 可以代替被动语态中的be

如get started, get paid, get married, get divorced, get separated, get worried about , get dressed, get changed, get hurt.

不能变为被动语态的情形:

1.主动句中的谓语动词是某些状态性动词时,这类动词强调“拥有,属于,存在”等含义时,不可变为被动语态。如have/own/possess/contain/exist/hold/lack/become/belong等。This museum owns 5,000 modern paintings, sculptures and drawings.

I have a computer.

2.某些不及物动词,不及物动词短语以及系动词用主动语态表被动意义,它们是没有被动语态的。

(1)表示主语内在“品质”或“性能”的不及物动词,如read/write/sell/wash/lock/shut/open/move/clean/catch/draw/cut等,其主语大多指物,且它们通常跟well/easily/badly等评价性副词连用。

This kind of book sells well.

The cloth washes well.

(2)物作主语的系动词,用主动形式表被动意义,同样没有被动语态,如feel/smell/taste/sound/prove/remain/stay/appear等。

The music sounds sweet.

The room belongs to me.

主动形式表被动意义:

1.不定式的主动语态表示被动意义:

(1)不定式在easy/difficult/fit等形容词之后,且不定式与句子的主语有逻辑上的动宾关系时,不定式常用主动形式表被动意义,且不定式的宾语必须省略。

The book is easy to understand.

(2)若作定语用的不定式与其所修饰的名词之间存在动宾关系,并与句子主语之间存在主谓关系,也可用主动形式表示被动意义。

I have a letter to write.

(3)某些作表语用的不定式,强调出租/责备/解雇等,也可用主动形式表示被动意义。此类常见的动词有:let(出租),rent(出租),hire(雇用),blame(责备)等。

Am I to blame?

2.用动名词的主动形式表示被动意义:

(1)在need/want/require(需要)/deserve(值得)等词后,用动名词的主动形式表示被动意义,也可以用不定式的被动形式。need doing = need to be done

(2)在形容词worth后,用动名词的主动形式表示被动意义,即be worth doing= be worthy to be done或be worthy of being done.

3.某些介词短语作表语时可表示被动意义:

under discussion under control under construction

under repair under consideration in the charge of

in use in print on show on sale out of control out of sight

4.被动形式表示主动意义

某些“动词+反身代词”结构,可变成被动结构表示主动意义。常见的这类结构有:devote oneself to, seat oneself, dress oneself, amuse oneself, lose oneself, prepare oneself for, concern oneself about等。

现在完成时被动语态教学设计

高中英语语法《现在完成时的被动语态》教学设计 一、教材分析 本节课的授课内容为被动语态中的一个重点也是难点的内容:现在完成时被动语态的学习及其应用。对于该内容学生半知半解,加上语法容易让人觉得枯燥,学生对此内容有排斥畏难心理。所以教学中将语法知识的传授和语言基本技能的学习结合到一起,注重学习语法与语言的运用。采用任务型教学法、情景教学法和小组合作探究学习法,让学生亲身去感知、领悟知识和运用知识,从而扩大课堂的语言输入量及学生的语言输出量,使其内容更加丰富,降低了语法学习的难度,同时也使语言学习和运用语言的过程成为一种栩栩如生的互动体验,提高了学习效率。 二、学情分析 授课对象为高一级的学生,他们来自全区各地初中,大部分学生的基础知识仍然较为薄弱,运用英语进行交际活动的能力较差,主动学习的动力不够,然而他们学习比较认真,渴求知欲旺盛,思维比较活跃。部分学生的基础较好,能主动配合老师。所以只有设臵使他们感兴趣的活动,利用发生在学生身边的事情——教室的环境布臵和学校艺术文化节作为语法学习的载体,因材施教,让学生明白所学语言知识的实用性,这样才能激发学生学习的积极性,并在师生互动、生生互动中实现教学任务和目标。 三、教学目标 知识与技能:1.让学生弄清楚现在完成时被动语态的结构和用 法; 2.重点是现在完成时被动语态的应用。 过程与方法:1.培养学生自主学习、协作学习和探究的能力; 2.培养学生分析问题、解决问题、归纳问题的能 力。 3.提高思维能力和运用英语的综合能力。

情感价值观:通过本节课的学习,培养学生热爱学校积极参与 学校活动的情感。 四、教学重点和难点 现在完成时被动语态的基本构成与实际应用。 五、教学策略和方法 本节课的教学以学生为中心,以教室的环境布臵和学校艺术文化节为载体,使课堂教学过程成为学生自主地进行信息加工、知识意义构建、归纳能力发展的过程。教师在教学过程中则适时介入,引导、启发、组织、帮助、促进。随堂进行小组指导,一方面参与学生的讨论,更给学生以个别辅导,以帮助学生解决学习过程中的难题。通过演示法把制作的课件、学生的作文等显示给学生看,便于学生对知识的把握,并从中获得启迪,从而解决问题。通过小组协作法分析问题、解决问题,从而内化而形成学习成果,并将其在全班学生中展示,使学生获得成功的喜悦,从而激发学生的后续学习热情。通过任务驱动教学法将所要学习的新知识隐含在语言操练之中,学生通过对呈现的图片进行分析、讨论,并在老师的指导、帮助下用本节课的语法对图片进行描述,以达到对语法项目的操练,最后通过任务的完成而实现对所学知识的意义建构。 六、板书设计 现在完成时被动语态的基本结构:have/has been done 七、教学过程 Step1 Revision (复习)(6分钟) 本单元学习的话题是计算机,计算机的应用很广泛,让学生在阅读里面找出介绍计算机应用的句子,并齐读句子:?The computers have been used in communication, finance and trade. ?The computers have been put into robots. ?It has been used to make mobile phones as well as help with

高一英语被动语态

高一专题系列一被动语态 ●学而时习 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。 ●知识点精讲透析 ●考点一主动语态“变性”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,如果主动句的宾语是代词,需变为主格。 (2) 将动词改为“be+过去分词”,be与新主语的人称和数一致,时态不变。 (3) 将主动语态的主语前加by放在谓语动词后,如果原主语是代词,要变为宾格。如: They held a meeting yesterday. → A meeting was held(by them)yesterday. 他们昨天开会了。昨天举行了一个会议。 They won’t forgive me. → I won’t be forgiven by them. 他们不会原谅我的。我不会被他们原谅的。 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”等,变为被动句时,通常删去“by…”,除非强调原主语。如: They set up this hospital in 1975. → This hospital was set up in 1975. 这所医院建于1975年。 Only he can finish the job. 只有他能完成这项工作。→ The job can be finished only by him.这项工作只能由他来完成。 (2) 含有双宾语,即直接宾语和间接宾语的句子,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. The truth was told (to) us by Jack. (3) 含有宾语+宾语补足语的句子,变成被动句后原来的宾语补足语就成了主语补足语了;注意:不带to的不定式作宾语补足语时,变成被动时要加上to。 I heard Emily sing the song just now. → Emily was heard to sing the song just now. 我刚才听见艾米莉唱这首歌了。 (4) 含有宾语从句的主动句变为被动句,通常用it作为被动结构的先行主语,把宾语从句后置。 We have determined that the plan should be carried out soon. It has been determined that the plan should be carried out soon. 我们决定这项计划必须马上实施。 (5) 双重被动结构: 当某人或物成为两次动作的承受者时,要用双重被动结构。如: Parents often ask their children to do too much homework. The children are often asked to do too much homework. Too much homework is often asked to be done by the children.

(完整版)一般将来时被动语态教案

一般将来时的被动语态教案 一、教学目标 知识目标:让学生在初中被动语态学习的基础上认识学习一般将来时被动语态的结构和用法。 能力目标:通过演绎归纳法让学生能够结合真实语境正确应用一般将来时被动语态。 情感目标: 在学习过程中,让学生学会探究合作,小组讨论等,以培养学生的集体合作精神;并且能够产生对于英语语法的兴趣。 二、重点难点 如何让学生更好的掌握一般将来时被动语态的结构和用法以及如何培养学生自主学 习和提高学生对于语法学习的兴趣。 三、学情分析 学生在初中阶段已经学习了被动语态,但是并没有将将来时被动语态单独提出来讲解,所以可能会有所混淆。更有甚者,可能有些学生将被动和主动都没有分清楚。 四、教学方法 演绎归纳教学和任务型教学 五、教学过程 Step1 Grammar revision Ask students what the form of the passive voice is and show them on the blackboard. 基本结构:be + p.p. 一般现在时被动语态:am/is /are + p.p. 现在进行时被动语态:am/is/are + being + p.p.

初中英语被动语态的教案

被动语态 授课人:授课时间: 一、语态概述 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。 He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句) 判断:你来判断哪个是主动哪个是被动? We call the doctor. People don’t play football here. The truck was cleaned yesterday. Mr Chen teaches us English. The classroom was cleaned. 二、被动语态的构成:be+动词的过去分词+by sb(be+done) 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 含有情态动词的被动语态:can/may/must/should... +be done

He opened the door.他开了门。(主动句) The door was opened.门被开了。(被动句) 说明:好了,现在我们对被动语态的句子形式有了一个形象的认识,但英语句子是千变万化的,这时就需要你有“火眼金睛”了。下面老师就来具体讲一讲被动语态的构成。 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。 说明:别看英语中一会儿主动被动一会儿现在时一会儿过去时啥的,好像看得咱们眼花缭乱啦。其实呢,这么一堆东西归纳起来,就两点:时态和语态。 一般现在时:am/is/are+taug ht 一般过去时:was/were+taug ht 一般将来时:will/shall be+tau ght 现在进行时:am/is/are being+taug ht 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。 说明:那么,什么时候用被动语态呢?简单的说,凡是汉语中带“被”的句子,都能转换成英语的被动语态。 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 computers 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 in1981.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 brok en 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。 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。 补充内容: 四、主动语态变被动语态的方法

中考被动语态详解 考情分析,中考对语态的考查侧重于以下几个方面: ①主动语态和被动语态的选择,含动词各种时态的被动语态形式, ②被动语态后的动词形式, ③主动意义表示被动意义的常见结构等等。 一、被动语态概念: 英语有两种语态:主动语态和被动语态。主动语态表示主语是动作的执行者,而被动语态则表示主语是动作的承受者。当主语为动作的执行者时, 谓语的形式为主动语态; 当主语为动作的承受者时, 谓语要用被动语态。 e.g. Many people speak English. (主动语态, 句子的主语many people是动作speak的执行者) English is spoken by many people. (被动语态, 句子的主语English是动作speak的承受者) 被动语态的用法 (1)当不知道或没有必要指出谁是动作的执行者时 Such books are written for children. 这些书是为儿童写的。 (2)强调动作的承受者,这时应用by短语 The cup was broken by David. (3)作客观说明时,常采用一种被动语态句型 It’s said / reported / + that …据说/据报道 It’s reported that it will rain tomorrow.据报道,明天会下雨。

二、主动语态被变动语态的方法 We Visited that factory last summer 主动语态 主语 谓语 宾语 状语 That factory was visited by us last summer 被动语态 主语 谓语 宾语 状语 (1) 把主动语态的宾语变为被动语态的主语。注意:如果主动句的宾语是代词,需将其由 宾格变为主格。 Tom killed him. → He was killed by Tom. (2) 把谓语变成被动结构(be +过去分词) They held a meeting yesterday. → A meeting was held by them yesterday. 他们昨天开会了。 (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。 三、各个时态的被动语态(3个一般,1个完成) 1、一般现在时的被动语态结构: →→

【教学内容】 一、被动语态的用法 1. 不知道动作的执行者是谁。如: This watch is made in China. 2. 没有必要指出动作的执行者是谁 More trees must be planted every year. 3. 需要强调或者突出动作的承受者时 Chinese is spoken by more and more people in the world. 4. 句子的主语不是人 Many buses were washed away by the flood. 二、 主动语态变为被动语态 We Visited that factory last summer →主动语态 last summer →被动语态 主语 谓语 宾语 状语 三、带双宾的谓语动词变为被动语态 有些动词带有两个宾语,即直接宾语和间接宾语,变被动语态时,可把其中一个宾语变成主语,另一个留在被动结构谓语后面。需要注意的是:若把直接宾语变成被动语态的主语,需要在间接宾语之间加上介词“to ”。 eg. He often tells us interesting stories . (主动语态) ? ??.h i m by us to told often are stories g Interestin .him by stories g interestin told often are We (被动语态)
