谓语动词被动形式
动作执行者
一般过去时的被动语态
1.主动语态表示主语是动作的执行者。
例如:
Many
people
speak
Chinese.
谓语：speak的动作是由主语many
people来执行的。
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:Chinese
is
spoken
by
many
people.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+be
not+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。
