have been doing 和having done的区别是什么

Question

Answer 1

have been doing 着重强调动作的持续性和反复性，突出这种持续和反复对现在造成的影响；having done 是动词ing形式的完成时，表示在谓语动词之前完成的动作。

Answer 2

have been doing是现在完成进行时，表示从过去某时开始一直持续到现在的动作，并且还将持续下去，或者表示在说话时刻之前到现在正在进行的动作；having done是动词ing的完成形式，表示该动作在谓语动词的动作前。

Answer 3

前一个是现在完成进行时态，强调的是从过去到现在，现在还在发生，如I have been studying here for two years，强调已经学了两年，现在还在继续（还未毕业）；后一个是现在完成时态，强调的是现在已经完成，如I have passed the exam，强调已经通过了考试。

have been doing是完成进行时，表示谓语的时态；having done是非谓语动词的完成时，表示分词的动作早于谓语动词的动作发生。
