回答1：

to have done 是表示主动意义的非谓语动词，发生在谓语动词之前；对应的被动形式是 to have been done；
having been done 是表示被动意义的非谓语动词，发生在谓语动词之前；对应的主动形式是 having done。

也就是说，在意义上，to have done = having done（主动）; to have been done = having been done（被动），都发生在谓语动词之前。

但是，除非连接在某些动词后，否则一律优先使用 having done 和 having been done，而不使用 to have done 和 to have been done。
