having been done是主动还是被动?

having been done 是主动还是被动,为什么have 出现having ing形式？分词是表示主动吧?看看这个句子our homework having been finished ,we went to play footabll.是不是说我们的作业正在被完成,我们去玩足球?还是说having been finished 是we这个主语的动作出发者,但是为什么having been finished 似乎跟主语we没关系,跟homework 有关系,但是我们的作业怎能可能自动完成呢?有人懂吗？

为什么是There having been? having been done 与done imressed by, having been impressed by being done having been done的区别 having been done和have been done的区别 She has been ill.She is having ___ leave. There having been no rain, the ground was dry. 请问这个句子里的 have been having 是什么意思 请问以下的having been completed 有没有这种结构？ having been done 和done作状语的区别
