Answer 2

这叫现在完成进行时，表示从过去到现在一直不停地做某事。如：I am very tired, for I have been walking for three hours. ( 我累死了，因为我一直不停地走了三个小时。

追答

之所以累死了，是因为一直不停地走。如果是have walked ，就有可能在三个小时的中途休息二个小时或者更多，那就不会累死了。

如还有疑问，欢迎追问，有问必答！

Answer 3

与现在完成时的唯一区别 就是现在完成进行时强调不间断地一直做某事。但二者都是现在还是这种状态。
如i have studied English for three years我学英语已经三年了。（现在仍然在学）
i have been studying English for three years。三年来我一直在学英语。（也是现在仍然在学）
