我套用一下我给另一位的回答，他也和你有相同的疑问：

She (is doing) her homework. （正在做）
She (was doing) her homework. （过去正在做）
She went out after she (had done) her homework. （用来区分两件事的先后顺序）
She (has done) part of her homework. （已经做了，现在还是）
She (has been doing) her homework for a while. （已经做了一段时间，而且还在做）
She (had been doing) her homework for a while. （已经做了一段时间，但已经不再继续了）

She (will have done) her homework by now. （预测这件事会在将来某个时间点完成）
She (will have been doing) her homework for days. （预测这件事会在将来某个时间点完成而且曾被持续的做）
还有被动式的情况如下。其变化原因与以上的例子相同：
Her voice (is being recorded). （正在被录音）
Her voice (was being recorded).
Her voice (has been recorded).
Her voice (had been recorded) before the cops broke in.
Her voice (will be recorded).
Her voice (will have been recorded) by now.
第二种是不行的。Be后面必须是PP。

第三种we have arrived是现在完成时，表示过去发生，或过去开始的动作，对现在造成影响。它与一般过去式的区别就在于：一般过去式只表示该动作发生在过去，并不强调对现在的影响。
如：I read the book.(我读过这本书。只说明有这个事实)
I've read the book. (我看了这本书。强调我了解这本书说的什么，知道这本书的内容)
