Having been done 是现在分词的完成时的被动语态，用的时候常常会出现一个段时间状语。如：
Having been built for two years, the building will be used as a hospital
done是过去分词，表示被动和完成，如
completed last month, the building will be used as a hospital
having done 是现在分词的完成时的主动形式，用的时候常常会出现一个段时间状语。如
Having worked for a long time , the workers are all very tired.
这些看完了你应该知道题目怎么做了吧
having been done 在句子中做的是状语。。前提是句子中有谓语的情况下。也就是有动词的时候用having been done 表别动，做状语！！
have done 就是谓语动词。。做句子成分。。句子中有东西了就不能用have done了
