为什么有have/has done 还有have/ has been done！！been 起了什

为什么有have/has done 还有have/ has been done！！been 起了什么动用！同样的is being epainted 有了be动词 怎么还要being

Answer 1

have/has done 是现在完成时，例：I have finished my homework.我已经完成了工作。
have/has been done表示现在完成时被动语态，例：My work has been finished.我的工作被完成了。been是完成时里被动语态的标志，去掉been就只是现在完成时而不是被动语态了。
is being painted里being 是进行时里被动语态的标志，去掉being就是一般现在时的被动语态。

Answer 2

been表被动比如，Tom has closed the door. The door has been closed by Tom.epaint是什么词。。。这里的being应该正在进行 比如 The flower is being watered.这个花正在被浇水。。。
