being done表示是正在进行的动作
The problem being discussed now has something important to do with our everyday life.
having been done 是发生的动作有前有后
Having been separated from other continents for millions of years,Australia has many plants and animals not found in any other country in the world.(分离的动作发生在前)
done是指两个句子前后主语一致,前面是被动时省略主语用done
建议你看一下刘悦诚编的高中英语语法书.
