一、语态概述
英语的语态是通过动词形式的变化表现出来的。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。
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。
例如:He opened the door.他开了门。(主动句)
The door was opened.门被开了。(被动句)
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。
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
歌诀是:被动语态be字变,过去分词跟后面。
三、被动语态的用法
1 被动语态
一. 一般现在时的被动语态
1. Football __________ (play) all over the world.
2. Many trees__________(plant) in North China.
3. A camera __________ (use) for taking photos.
4. I ________ often ________(ask)to do this work.
二. 现在进行时和过去进行时的被动语态
1. The rooms __________ (paint)now.
2. Trees __________(plant) here this time last year.
三. 一般过去时的被动语态结构
1. The house __________(build) in 1978.
2. All the students _____________ (ask) to bring a kite with them last Sunday
3. The car _________(clean) by Dad yesterday.
4. When the present (give)to him by his mother?
四. 一般将来时和过去将来时的被动语态
1. Our English teachers __________(send) abroad for further education.
2. A class meeting __________(hold) next Monday.
3. She said the work _________(finish) by the end of the year.
单元知识点
被动语态
1.英文动词有主动语态Active Voice和被动语态Passive Voice之分。如果主语是动作或状态的“发出者”,动词就用主动语态;如果主语是动作或状态的“承受者”,动词就用被动语态。例如:
John encouraged Mary. 约翰鼓励玛莉。
Mary was encouraged by John. 玛莉受到约翰的鼓励。
第一句的动词“encouraged”是主动语态;第二句的动词“was encouraged”是被动语态。
2.动词的被动语态的形式是:be+动词的过去分词
3.动词由主动语态变为被动语态的步骤:将宾语变为主语;根据新主语的人称和数,并考虑时态,然后决定“be”的形态;将旧主语放在“by”之后构成介词短语。下面是一些例子:
(1)Simple Present Tense
主动语态:I teach him.
被动语态:He is taught by me.
(2)Present Continuous Tense
主动语态:I am teaching him.
被动语态:He is being taught by me.
(3)Present Perfect Tense
主动语态:I have taught him.
被动语态:He has been taught by me.
(4)Present Perfect Continuous Tense
主动语态:I have been teaching him for a week.
被动语态:He has been being taught by me for a week.
(5)Simple Past Tense
主动语态:I taught him yesterday.
被动语态:He was taught by me yesterday.
(6)Past Continuous Tense 主动语态:I was teaching him when you came.
一、语态概述

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
