结构
The Present Perfect Continuous Tense
基本结构：have/has been doing
否定结构： have/has not been doing
用法
① We have been waiting for you for half an hour.
② Chinese have been making paper for two thousand years.
①动作发生在过去，刚终止，不再继续下去。
②动作发生在过去，还将继续下去。
Present
Past
Future

3. Tom has always been working hard.
4. What have you been doing to my dictionary
④带有感彩，使语言表达更加生动。
赞许的感彩
不满的感彩
Summary：现在完成进行时的用法
1.表示动作从过去某一时刻开始一直持续到现在，甚至将来，强调进行的过程。
2. 表示从过去到现在的一段时间反复进行的动作或存在的状态。常常含有感彩，如：赞赏、批评、愤怒等。
Look & discover:
① A private detective has been tailing (跟踪) him for several weeks.
② Tom loves outdoor activities - he has been fishing and hunting since he was a child.
Summary:
现在完成进行时常与以下时间状语连用：
for .../since ...
all day/ all night/ whole week/ all the time/ these days/ ...
from the start, in/over the past/last few weeks ...
recently/ lately/ during .../ ...
常用的时间状语
现在完成时 VS 现在完成进行时
（have/has done) (have/has been doing)
注意：现在完成进行时无被动语态
【相同点】
表示延续性，且都有延续性的时间状语时，两者用法差不多。现在完成进行时更强烈暗示动作或状态的延续，完成时表示动作可能延续。
I have been teaching for two years. 我教了两年书。（未来持续)
I have taught for two years. 我教了两年书。（可能延续）
【区别1】
现在完成时：表示动作已结束 ，强调结果
现在完成进行时：表示动作（延续性动词）仍在进行，强调动作
She has written three letters this morning.
She has been writing letters this morning.
【区别2】
现在完成时：强调结果，能说出具体重复次数。
现在完成进行时：强调动作，不能说出重复的次数
【区别3】
现在完成进行时：不能用状态动词
（常用表状态、情感、感觉的动词: have, exist，like, hate, hear, know, believe, want, regret, prefer, smell, feel, taste, last等不能用于现在完成进行时，但可用于现在完成时。）
