英语动词有两种语态，主动语态和被动语态。
主动语态表示主语是动作的执行者
例如：Many people speak English.
He opened the door.
We will repair this watch in two days.
被动语态表示主语是动作的承受者。
例如：English is spoken by many people.
The door was opened.
This watch will be repaired by us in two days.
被动语态构成：be+p.p.
语 态 分 类
被动语态的定义：
语态是动词的一种形式，用以表示主语和谓语之间的关系。当主语是谓语动作的执行者，则为主动语态；当主语是谓语动作的承受者，则为被动语态。
被动语态由助动词be + 过去分词构成，时态通过be表现出来。
一般现在时—— am／is ／are + v.p.p.
一般现在时的被动语态：
A recorder is used in our English class every day.
Football is played all over the world.
Cameras are used for taking photos.
被动语态的构成：be +vt.p.p.
