英语动词有两种语态,即主动语态（TheActiveVoice）与被动语态（ThePassiveVoice）。

主动语态表示主语是动作的执行者;被动语态表示主语是动作的承受者。

主动语态,被动语态,主动语态,被动语态,e.gManypeoplespeakEnglish.,主动语态变被动语态的步骤：

1、主动语态的宾语变为被动语态的主语；2、主动句的谓语动词变为被动结构；3、主动句的主语变为被动句的宾语，由by引出，当不强调动作的执行者时，常省略。

4.其它成分不变。

变被动语态时需要注意的事项,一变二套三注意,宾变主，主变宾，宾语前面by跟，谓语动词变过分，不忘前面be动词跟,套时态，主被动时态一致,注意因人称的变化而引起的主谓一致问题。
