【学习过程】
一、语法点拨。
现在完成时与现在完成进行时的比较：
（1）现在完成时表示到现在为止已经完成，或者在过去曾经发生过的动作；现在完成时往往表示仍将继续下去的动作。
例：①I have written an article.
我写了一篇文章。（已完成）
②I have been writing an article.
我一直在写一篇文章。（还在写）
③They have built a ship.
他们建了一艘船。（已完成）
④They have been building a ship.
他们一直在建一艘船。（还在进行）
（2）当现在完成进行时表示刚刚结束时，现在完成时强调动作的结果，现在完成进行时则强调动作在不久以前持续进行的情景，并带有感彩。
例：Now we have cleaned the room, we can move the things in.
现在房子打扫好了，我们可以往里搬东西了。（强调打扫完了的结果）
（3）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。
例：I’ve known him for many years.
我认识他有许多年了。
