第十七讲被动语态
(完整版)初中英语被动语态
一、语态概述
语态是动词的一种形式,表示句子之中主语和谓语动词的关系.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发出者(或执行者)eg: 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.eg: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
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.(被动语态
的否定式和疑问式均由助动词或第一个助动词构成.)
各种时态的被动语态构成:
1. 一般现在时:am/is/are +及物动词的过去分词
I'm asked to take care of myself. Football is played all over the world
2. —般过去时:was/were +及物动词的过去分词
This house was built in 1958. His leg was broken in an accident.
3. 一般将来时:will/shall be +及物动词的过去分词
More factories will be built in our city. He will be taken to hospital tomorrow.
4. 现在进行时:am/is/are bei ng +及物动词的过去分词.

语义差异
被动语态强调动作承受者 ,而系表结构强调主语的 特征或状态。
时态与助动词
被动语态需要与时态和助 动词配合使用,而系表结 构则不需要。
误用案例分析
混淆两者结构
有时会将被动语态的结构误用为 系表结构,导致句子语法错误。
误用系动词
在应该使用被动语态的情况下,错 误地使用了系动词,导致句子意义 不清。
疑问形式
Have/Has + 主语 + been + 动词过 去分词 + 其他
特殊疑问句
特殊疑问词 + 一般疑问句
03
特殊情况下的被动语态应用
带情态动词的被动语态
情态动词+be+过去分词
表示对现在或将来的被动动作,如“The work must be finished by tomorrow.”(这项工作必须在明天之前完成)。
一般过去时表示过去某一时间发生的动作。 • 去掉is selling,改为一般现在时。因为sell可用作及物动词,也可用作不及物动词。用作及物动词时表示卖的
具体动作,其主语是人;用作不及物动词时表示主语的特征或状态,其主语通常是物。此处表达的是书的特点 ,应该用一般现在时的主动语态。 • 将is being built改为has been being built。因为时间状语now for two years表示到目前为止已经持续了两 年的动作,所以应该用现在完成进行时的被动语态。

找出文章或段落中的 被动语态句子,并尝 试转换为主动语态。
将被动语态句子转换 为主动语态句子。
疑难问题解答
何时使用被动语态? 当动作的执行者不重要或不明确时。
当需要强调动作的对象而不是执行者时。
疑难问题解答
当避免使用“I”或“we”等主观性 强的词语时。
被动语态中的过去分词表示动作已完 成,而作定语时则表示状态或特征。 可通过上下文及语境进行判断。

定义及作用
定义
被动语态是动词的一种形式,表 示主语是动作的承受者,即动作 的对象,而不是动作的执行者。
时态和人称变化
时态变化
被动语态的时态变化主要体现在be动词和助动词上,如一般现在时的被动语态为 “am/is/are+动词的过去分词”,一般过去时的被动语态为“was/were+动词 的过去分词”等。
人称变化
被动语态的人称变化也主要体现在be动词上。例如,一般现在时的第三人称单数 的主语,其被动语态的be动词用is;而第一人称和第二人称的主语,其被动语态 的be动词用are。

被动语态(讲解)(DOC)
By-Bevis 被动语态By-Bevis
英语中语态是动词的一种形式,用来说明主语和谓语动词之间的关系。分为主动语态、被动语态两种。即主语“做某事”(主动)或者主语“被做某事”(被动)。汉语中所说的“课桌被修好了”,“房子是由工人们建的”这样的在动词前面加个“被”字、“由”字的句就是一种被动语态的句型,在英文中则用动词的被动语态形式表示。
一、语态的种类:
语态定义
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着,即动作发生的对象
例句主动:Lily asked the question. 我问了这个问题
被动:The question was asked by Lily. 这个问题是由我问的
二、被动语态的基本构成形式:Be动词+ 动词的过去分词形式(由两部分构成)
三、被动语态的时态结构变化(主动语态以动词ask 为例)
时态结构、例句
一般现在时They ask a question(主动)
肯定式:否定式:疑问式:主语+am/is/are+动词过去分词+其它+by+介词宾语
A question is asked by them.
主语+am/is/are+not+动词过去分词+其他++by+介词宾语A question is not asked by them.
Am/is/are+主语+动词过去分词+其他+by+介词宾语
Is a question asked by them?

被动语态讲解
一、总述:
英语动词有两种语态,即主动语态(The Active Voice)和被动语态(The Passive Voice)。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。
They will build a new bridge over the river. (主动)
A new bridge will be built over the river. (被动)
汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:
助动词be + 及物动词的过去分词构成。
二、被动语态的形式
1) 常用时态的被动语态的构成:
被动语态的基本形式为助动词be + 及物动词的过去分词,即be done。
被动语态的时态、人称和数的变化主要体现在be的变化上,其形式与系动词be的变化形式完全一样.以give 为例,列表如下:
一般现在时:am / is / are + given
一般过去时:was / were +given
一般将来时:shall / will +be+ given
过去进行时:was / were + being + given
现在进行时:am / is / are + being + given
过去完成时:had + been + given
现在完成时:have / has + been + given
将来完成时:shall / will + have been + given
过去将来时: should / would +be+ given
现在完成进行时:have/has been being done
语法被动语态讲解
被动语态
一、定义:主动语态表示主语是谓语动词所表示的动
作的执行者;被动语态表示主语是谓语动词所表示的动作的承受者。
常见考点有:
被动语态的基本结构及转换方法
主动结构表示被动意义
省略to 的不定式作补语在被动语态中符号to 的保留
二、被动语态的基本结构及转换方法
被动语态的基本结构是“be+过去分词”,各种时态的被动结构需将被动式与时态的构成方式合二为一,即将构成被动语态的be看作时态中的谓语动词,并将其做相应的变化。
主动句中的主语放在介词by之后做宾语,如果是代词,将主格改成宾格,by短语可省略。
All the people laughed at him.→He was laughed at by all people. 所有人都嘲笑他。
They make the bike in the factory.→The bike are made (by them) in the factory.
1.只有及物动词有被动语态,不及物动词没有被动
语态。
Great changes have taken place in our hometown
these years. 这些年我们的家乡发生了巨大的变
话。
2.主动句中带有双宾语的动词在被动句中可用直接
宾语或间接宾语作主语,但用直接宾语作主语时
在间接宾语前应加上介词to 或for。在动词pass,
give, post, leave 等后应加介词to, 而在动词buy,
sing, cook, draw, make 等后应加介词for。
I’ll give her a present for her birthday.→A present

第十七章 被动语态 一、被动语态概述 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谓语动作的执行者,被动语态表示主语是谓语动作的承受者,其构成为be+过去分词,例如: A letter was typed by Mary. The girl is taken care of by her mother. 被动语态各种时态形式如下:一般现在时: am / is /are asked一般过去时: was /were asked一般将来时: shall / will be asked现在进行时: am / is / are being asked过去进行时: was / were being asked现在完成时: has / have been asked过去完成时: had been asked将来完成时: shall / will have been asked过去将来完成时:should / would have been askedNote:1.含有情态动词的谓语变为被动语态时,由“情态动词(can, may, must等)+be+过去分词”构成。例如: The work must be finished in two days.2.含有“be going to, be to”等结构的复合谓语变为被动语态时,其结构分别为 "be going to be+过去分词,be to be+过去分词"。例如 : Another railway is going to be built in this area. The trip is to be cancelled because of the bad weather.二、被动语态使用要点(一)不及物动词不能用于被动语态 有些不及物动词不能用于被动语态,如appear, rise, die, happen, occur, lie, depart, belong to, break out, take place等都属此类动词。例如: Great changes have taken place in my hometown. (正) Great changes have been taken place in my hometown.(误) (二)表示状态的动词不能用于被动语态 英语中有些动词(短语动词)不是表示动作,而是表示某种状态或情况,这类动词不能用于被动语态,常见的有:lack, fit, mean, hold, resemble, have, cost, equal, contain, suit, comprise, become, last possess, benefit, lack befall,fail, consist of, look like等。例如: The book costs ten yuan. (正) Ten yuan is costed by the book. (误) Jane resembles her mother.(正) Her mother is resembled by Jane.(误)Note:当have作“吃,接收,经历,度过”解时,虽用作行为动词,但一般不用于被动语态。例如: The children had a most enjoyable holiday.(正) A most enjoyable holiday was had by the children.(误)但当have作“得到,获得,欺骗”解,或同某些介词、副词结合构成及物性短语动词时,可用于被动语态。例如: She has been had in the dealing. Geogred has been had over the bargain. The ticket can be had for the asking. (三)某些动词的进行时也可表示被动意义 某些动词的进行时也可表示被动意义,常见的这类词有:bake, owe, cook, print, do

第十七讲:被动语态
被动语态( Voice)是个语法范畴,是表示主语和动词之间语法意义和语义关系的动词形式。英
语动词有主动和被动两种语态,当主语是动词的发出者时,动词用主动语态(
Active V oice);当主语
是动作的承受者时,动词要用被动语态( Passive Voice)。 只有及物动词才有被动语态。 如:
Scientists have been puzzled for decades by how turtles manage to navigate across the Atlantic; but
now they know . 几十年来,科学家一直对海龟如何能穿越大西洋迷惑不解;但现在他们知道了。 这句话中, scientists 是 puzzle 的承受者, 故 puzzle 用被动语态。 They 是 know 的发出者, 故 know
伪装了起来。 )
4.
All the apparatus had been prepared before the experiment began(. 所有的器械在实验开始前
就准备好了。 )
5.
The world ’s supplies of copper are being gradually exhausted.(世界的铜资源正在逐渐被耗
① They have talker about this matter recently.
This matter has been talked about recently. ② We have never heard of such a thing before.
Such a thing has never been heard of before. ③ They looked after the old man carefully.
2.表示状态的动词不能用于被动语态
英语中有些动词(短语动词)不是表示动作,而是表示某种状态或情况,有“拥有、容纳、适
合、缺少、明白”等意,这类动词不能用于被动语态,常见的有:
lack, fit ,mean, hold , resemble,
have, cost,contain ,fail , consist of , look like 等。例如: The book costs10 yuan.
Note: pay attention to, take care of 等短语动词可以有两种被动语态形式。例如: The situation has been paid attention to.
