关于被动语态（专家帮忙）

been done 才是被动语态 你理解错误拉 给你一个我认为的被动语态解释的最好的一份说明把 英语专家回答 版权所有抄袭可耻

英语中有主动和被动两种语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。只有及物动词才有被动语态。被动语态由“助动词+及物动词的过去分词”构成。被动语态的助动词同样有时态、人称和数的变化。
1.A new computer was bought to me by my father yesterday.
2.The children are looked after very well by Mrs Zhang.
3.He was seen to come into the meeting-room.(这里注意一下：由于see是感官动词，所以改为被动语态后要加to)
4.English is found very useful by us.
5.A lot of trees are planted by him.
后面的“by…”可加可不加，只要句子表示的是被动的意思就可以了。

很简单把 注意到了没有 被动语态前面都是有be动词的 就是 is are was been等

据个例子？？

been done 是表被动，现在完成时用.而done则表示做过了某事，不表示被动。

eg: The floor has been cleaned. 地板已经清扫过了。 （注意是已经)

eg: We are done! 我们分手了！
