肯定句：主语 + have/has + been + 现在分词...
否定句：主语 + have/has + nt + been + 现在分词...
疑问句：Have/Has + 主语 + been + 现在分词
疑问代词/ 疑问副词 + have/has +（主语 +）been + 现在分词
【设计意图】通过观察，感知、理解现在完成进行时的用法和功能。
具体分析现在完成进行时的不同用法
（1）表示动作从过去某时开始，一直延续到现在，并有可能持续下去。
He has been watching TV fr three hurs, and he is still watching nw.
他已经连续看了三个小时电视，现在还在看。
I have been ding my hmewrk the whle mrning.
我一整个早上都在做作业。
His brther has been writing this nvel since last year.
他哥哥从去年起就一直在写这本小说。
现在完成进行时常和all this time, this week, this mnth, all night, all the mrning, recently 等状语以及since和fr引导的状语连用。
（2）表示动作发生在过去，到现在刚刚结束。
Where have yu been? I have been waiting fr yu fr a lng time.
你刚刚去哪儿了？我等了你好久。
My clthes are all wet. I’ve been wrking in the rain.
我衣服全湿了。我刚刚一直在雨中工作。
（3）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，而不是动作并不是一直不停地进行。
Jack has been phning Jane every night fr the last week.
Jack上周一直给Jane打电话。
I have been telling yu nt t make truble.
我一直劝你不要找麻烦。
My mther has been practicing Tai Chi fr mre than a year.
我妈妈练太极一年多了。
（4）表达感概、赞许、不满等感情色彩，使语言表达更生动。
Tm has always been wrking hard.
Yu have been cughing a lt lately!
What have yu been ding t my dictinary?
【设计意图】通过例句学习现在完成进行时的不同用法和功能，识别现在完成进行时的时间状语。
Step 3 Cmpare and find 比较四组例句，发现现在完成进行时与现在完成时的区别
① He has been writing a nvel, which will be finished next mnth.
He has written a nvel, which is being prepared t cme ut nw.
总结：have been ding强调动作未完成 (一直)；而have dne强调动作已经结束 (已经)。
② I have been visiting my hmetwn recently, and it impresses me differently each time.
I have visited my hmetwn recently, whse changes have left a deep impressin n me.
总结：have been ding强调动作的重复，have dne可以表示一次性动作。
③ The repairman has been repairing the car all the afternn.
The repairman has repaired yur car, and yu can have it nw.
总结：have been ding只强调动作行为本身，而have dne强调动作行为的结果、影响。
④ Where have yu been? We have been lking fr yu everywhere.
We have lked fr him, but haven’t fund him.
总结：have been ding表示一种感情色彩；have dne则陈述一种事实。
现在完成进行时与现在完成时的区别
⑤ 有些动词不能用于现在完成进行时，但可用于现在完成时：
状态动词：be, have, exist;
情感动词：like, lve, hate;
感观动词：see, hear, knw, feel, sund;
短暂性动词：finish, marry, get up, cme, g等。
I have knwn him fr years.
I have been knwing him fr years.
They have finished the wrk.
They have been finishing the wrk.
总结：一些表状态、情感、感官类的动词以及短暂性动词不能用于现在完成进行时，但可用于现在完成时。
【设计意图】分析、判断现在完成进行时和现在完成时的区别，深入理解和运用这两个时态。
