had been doing 和had been done区别1、首先要区分has been done与 had been done的区别：
have/has been done 是现在完成时的被动语态。表示某事被做，。
如：The problems have been solved.这些问题已经被解决了。
had been done 则是过去的过去，是过去完成的被动态时。(当你想说发生在过去的两件事时，就要分清谁先谁后。先发生的用过去完成时，后发生的要用过去时)。
如：The rooms had been cleaned when I came. 我来的时候，房间已经被打扫了。
2、区分has/have been doing与 had been doing
has/have been doing是现在完成进行时，并对现在有影响。
如句子：I have been dreaming all the night.
had been doing是过去完成进行时，也是过去的过去，需要时间先后顺序的对比.
如：I had been doing the cleaning before my mother arrived at home.
那么现在就可以区分had been doing 和had been done的区别了
