英语完成时、进行时，既可以作为两个相对独立的时态，也可以组合为一种新的时态，即“完成进行时”。完成进行时是从动作的持续状态的角度来看待一个动作的。如果再从时间的角度来看，它又可以分为过去完成进行时、现在完成进行时、将来完成进行时以及其它的一些时态。下面结合实例，来简要地叙述一下完成进行时的用法。

如果单独看完成时态，它有一个基本的含义即表示到某个时间为止，该动作已经完成，所以它称作“完成时”。但是，在完成进行时里面，一般情况下，它并不表示动作的“完成”，而是表示长时间的持续状态。也就是说，完成进行时侧重于“进行”。

如果单独看进行时，它表示某个时间内动作正在进行，而完成进行时则侧重于长时间的持续状态。如果简单地说，完成进行时实际上是一种强调动作持续发生的进行时，并且含有动作反复进行的意思。

以上就是完成时、进行时、完成进行时之间的联系和区别。
