had been doing 和had been done的差別1、首先要區分has been done與 had been done的區別：
have/has been done 是現在完成時的被動語態。表示某事被做，。
如：The problems have been solved.這些問題已經被解決了。
had been done 則是過去的過去，是過去完成的被動態時。(當你想說發生在過去的兩件事時，就要分清誰先誰後。先發生的用過去完成時，後發生的要用過去時)。
如：The rooms had been cleaned when I came. 我來的時候，房間已經被打掃了。
2、區分has/have been doing與 had been doing
has/have been doing是現在完成進行時，並對現在有影響。
如句子：I have been dreaming all the night.
had been doing是過去完成進行時，也是過去的過去，需要時間先後順序的對比.
如：I had been doing the cleaning before my mother arrived at home.
那麼現在就可以區分had been doing 和had been done的區別了
