初中英语被动语态教案

被动语态教案

被动语态

1. 英语中有两种语态：主动语态和被动语态。

含义：主动语态表示主语是动作的执行者。I beat Fujian.

被动语态表示主语是动作的承受者。Fujian is beaten by me.

2. 被动语态的构成:

被动语态由be＋过去分词构成，be随人称、数和时态的变化而变化。

The apple is eaten by me.

I am respected by my students.

Many trees were planted by us last year.

3. 主动语态变被动语态的方法:

主动语态 宾语

被动语态

主语 谓语 宾语

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） （根据被动语态的主语的人称和数和主动语态句子中时态来决定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, 有时by短语可以省略。 主动语态 被动语态
