初中英语 被动语态
同学们，初中阶段的八种时态我们已经学 完了。
时态表示的是动作在什么样的时间之下发 生的，强调的是时间概念，所以关于这八种 时态的各自时间状语大家一定要记准。
今天我们来学习语态。
什么是语态呢？ 语态有几种呢？
英语语态
语态是动词的一种形式，表示主语和动词之间的关 系。
英语动词有两种语态：主动语态和被动语态。
→ 3000 English words have been learned by us so far.

Tom broke the windows. The windows were broken by Tom. He broke the windows. The windows were broken by him.
过去进行时
was/were being + done
一般将来时
shall/will be + done
过去将来时
would be + done
现在完成时

过去完成时

有及物动词才有被动语态，不及物动词没有被动语态。
