现在完成时和现在完成进行时的区别
区别一： 现在完成进行时表示的动作很可能要持续下去。 而现在完成时则表示动作已结束。 The students have been preparing fr the exam. （还在进行）学生们一直在准备考试。 The students have prepared fr the exam. （已经结束）学生们为考试作了准备。
区别二：现在完成进行时强调动作持续的过程。现在完成时强调动作的结果或成就。My hands are very dirty. I’ve been painting the huse. I have painted the huse green. The huse was white, but nw it’s green. I’ve been cleaning the huse but I still haven’t finished. I’ve cleaned the huse, but I still haven’t finished.
现在完成进行时比较生动，有时含有明显的感情色彩，而现在完成时往往只说明一个事实，一种影响或结果。
Wh’s been eating my apples？ 　　Wh’s eaten my apples？
(1)进行时态表示“苹果可能未被全部吃光” (2)有强烈的感情色彩，表示愤怒不满。
(1)完成时态表示“苹果一个不剩了”(2)只是希望回答一个问题。
I have waited fr tw hurs. 我等了两小时。(陈述事实)I have been waiting fr tw hurs. 我等了两个小时。(等得好辛苦)
区别四：现在完成进行时态不能用来谈某个动作的具体次数或几件事情。 I have been drinking five cups f cffee this afternn. I have drunk five cups f cffee this afternn.
相同点一：后面都可以跟fr、since引导的时间状语。相同点二：一般疑问句的简略回答一样：Yes, I/we/they have. N, I/we/they haven’t.Yes, he/she/it has. N, he/she/it hasn’t.相同点三：现在完成进行时不用于被动语态，若要用可用现在完成时的被动语态代替。
