现在完成进行时学习精华

现在完成进行时 表示动作发生在过去一直持续到现在，和现在完成时相比，它强调动作的持续性。现在完成时表示动作已经终结。

e.g. My hands are dirty. I have beenpainting the wall.

也可表示短期时断时续，重复发生的动作

e.g. He has been phoning Jenny every nightfor a week.一直在打电话（断断续续地进行着）

如果强调的是动作一直在持续下去，或者是一直在断断续续地进行着，这时句子用现在完成进行时。

Over the past decades，sea ice in the Arctic has__been__decreasing(decrease)as a result of global warming.一直在减少

Tom has__been__working(work)in the library every night these days.

     一直在工作（断断续续地进行着）

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。

Eg: He haschanged his idea. 他改变了想法。

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。

Eg: We have beenstudying here for two years. 我们在这儿已经学习了两年了。

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 cleanedthe window. 他把窗户擦干净了。(动作已完成)

He has beencleaning the window. 他一直在擦窗户。(动作不一定完成)

 

现在完成进行时学习概要

参考答案

 

Dashan,who (learn)crosstalk,the Chinese comedic tradition,for decades,wants to mix it up with theWestern stand-up tradition.(江苏真题) 

【答案】 has been learning

【解析】本题考查动词的时态。句意:大山学习相声——中国的传统喜剧形式——数十年了,他想把中国相声与西方的脱口秀融合起来。由for decades可知who引导的非限制性定语从句要用完成时,再由主句谓语动词wants可知应用现在完成进行时(has been learning)。

---We’ve spent too much money recently.

----well, it isn’t surprising. Our friendand relatives _______around all the time

A.are coming    B. had come    C. werecoming        D. have been coming

答案：D.“近来我们花了太多钱了。----并不惊奇，近来朋友和亲戚总是来访。”用have been coming表示从过去到现在一直发生的动作。

—Excuse me,which movie are you waiting for?

—The new Star Wars.We (wait) here for more than two hours.(北京真题) 

【答案】 have been waiting 本题考查动词的时态。句意:——打扰了,你们在等着看哪部电影呢?——新版的《星球大战》。我们在这儿等了两个多小时了。结合句意可知,此处表示一直在等待着,并且还有可能继续等下去,故用现在完成进行时(have been waiting)。
