4.现在完成进行时与现在完成时的区别
(1)现在完成时强调动作的完成,而现在完成进行时强调动作的延续。因此,表示动作的完成,只能用现在完成时,而不能用现在完成进行时。

他改变了想法。
I have already read the book.
我已经读过这本书了。
(2)在表示动作的延续时,虽然既可用现在完成时,也可用现在完成进行时,但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时,应用现在完成进行时。
We have been studying here for two years.
我们已经在这儿学习了两年。
She is very tired.She’s been working all morning.
她很累。她干了一上午活了。
(3)在许多情况下,现在完成时表示动作已经完成,而现在完成进行时却并非如此。
He has cleaned the window.
他把窗户擦干净了。(动作已完成)
He has been cleaning the window.
他一直在擦窗户。(动作不一定完成)
(4)有些静态动词只能用于现在完成时,一般不能用于现在完成进行时。
I’ve known him for many years.
我认识他有许多年了。
The war has lasted for a long time.
这场战争持续了很长一段时间。
