注意以下几类词无被动语态：
1.不及物动词没有被动语态
2.常见的系动词如feel,smell,taste,look, sound,go(变得)，grow（变得）等，无被动语态
3.表示发生的动词（短语）无被动语态，如take place, happen, break out。
1. He breaks the window.
The window is broken by him.
2.We gave the student some
books.
The student was given some books by us.
Some books were given to the student by us.
Observe & Conclude:(把主动句变成被动句，并观察总结规律)
主动
被动
主动态变被动态的口诀：
“助动词be＋及物动词的过去分词（＋by＋动作执行者）”
宾语提前主语变，时态人称“be”关键，
过去分词勿变错，原主变宾“by”后见。
