(The Passive Voice)

英语动词有两种语态,即主动语态(The Active Voice)与被动语态(The Passive Voice)。 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。
e.g. 1.They make trains in Zhuzhou . Trains are made in Zhuzhou. 主动语态 被动语态 主动语态

2.The farmers grow cotton every year.

Cotton is grown by the farmers every year. 被动语态

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。 e.g Many people speak English.

所有时态的被动语态否定就是在 最前面的助动词后加 not
