动词的语态:
动词的语态有主动语态(主语是动作的发出者)和被动语态(主语是动作的承受者)。被动语态由be/get+过去分词构成,be/get体现时态变化。主动变被动时,时态保持不变;动作的执行者由by短语表示;get+过去分词侧重动作的效果,通常不与表示一段时间的状语连用,其一般现在时/一般过去时变否定式,疑问时要借助助动词。
They make bikes.
Bikes are made by them.

How did the window get broken?
注意:
(1)不及物动词一般没有被动语态。
The sun sets in the west.
易错的常见的不用被动语态的不及物动词有:rise, set, happen, break out, take place, fall, lie, die, etc.
