 主动变被动的方法

 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。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 by them in the factory.

 口诀：宾变主，主变宾，谓变 be done ,时不变，数格必须随被变。
