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。
eg. Many people speak English. 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。
eg. English is spoken by many people.主语English是speak的承受者。
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。
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 (p.p)
English is taught in many other countries.
一般过去时
was／were＋taught (p.p)
An English song was taught by our teacher yesterday.
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
eg. Some new computers were stolen last night.
(2)强调动作的承受者，而不强调动作的执行者。
eg. The window was broken by Mike
四、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。
eg. All the people laughed at him.
He was laughed at by all the people.
