例如:ManypeoplespeakChinese.

2.被动语态表示主语是动作的承受者，即行为动作的对象。

例如:Chineseisspokenbymanypeople.主语English是动词speak的承受者。;被动语态的句型总结如下：

肯定句:主语+be+过去分词(+by…).

否定句:主语+benot+过去分词(+by..)

一般疑问句:be+主语+过去分词（+by…）？

特殊疑问句:特殊疑问词+be+主语+过去分词（+by…)?;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speak为例说明被动语态在各种时态中的构成。;YouthCenter;Theywilldesignaposter.;Theywillseefilmsaboutenvironment.;Alotofactivitieswillbeorganized.
