现在完成进行时。
有现在完成时的特点，也有进行时的特点。
be doing 进行时
have done 完成时
have加上 be、动词的过去分词
have been doing
been 是be动词的过去分词。用于完成时。在have 的后面。
过去分词和 be动词表示被动。但 be动词的过去分词没有实际动作含义。不像其他动词。
She is told by her sister that her mother is ill.
被 告诉 told
不可能被 been 的
您说的情况可能是 完成时的被动语态，没大弄清楚吧。
have been done
The room has been cleaned already.
被动语态体现在 been cleaned 上。是 be动词加上 过去分词。而been 是完成时的过去分词。
而不是只有在被动语态是才用的。
希望能帮到您。祝进步！
