『壹』 关于英语语法中的主动和被动
公式：be+动词的过去分词
应用范围：表示被动的情况，一般是及物动词有被动语态，切记不及物动词与一些固定词组是没有被动语态的。例如：happen, take place
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)
歌诀：谁做的动作不知道，说出谁做的没有必要；
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。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
『贰』 主动句.被动句分别用英语怎么说
一、被动语态的构成
被动语态由“be动词+过去分词”构成：如
Everybody likes the cute girl. 大家都喜欢这个可爱的女孩。(主动语态)
The cute girl is liked by everybody. 这个可爱的女孩受到大家的喜欢。(被动语态)
二、主动语态变被动语态的基本方法
将主动语态的宾语变为被动语态的主语，将主动谓语变为被动谓语(be+过去分词)，将主动语态的主语变为by短语(在被动句中用作状语)，如：
He finished the task. → The task was finished by him.
注：如果不强调动词发出者，被动语态中的by短语通常可以省略。
三、 特殊用法
主动句可以转换成两种被动句型，它们通常是一些表示客观说明的句子，如：
People believed that the old man is innocent. 大家相信那个老人是无辜的。
→ It’s believed that the old man is innocent.. 大家相信那个老人是无辜的。
→ The old man is believed to be innocent. 大家相信那个老人是无辜的。
比较上面两类被动句型可以发现，一类是“it+be+过去分词+that从句”，另一类则是“主语+be+过去分词+不定式”，通常可用于这两类被动句型的动词有suppose, think, understand, assume, believe, expect, presume, report, say, fear, feel, know,等，如：
It’s known that she is a kind girl. =She is known to be a kind girl. 大家知道她是个善良的女孩。
It’s expected that he will be better soon. = He is expected to be better soon. 他应该很快就会好起来。
以上就是主动句变被动句的方法，大家都学会了吗？其实，主被动在我们写作或翻译过程中还是非常重要的，英语多被动，汉语多主动，所以学会这两种语态的转变对我们今后的学习至关重要。所以，希望大家能多思考对比，反复练习运用，尽快掌握该知识点。

by引导的介词短语，比如：
