2．现在完成进行时的用法①表示动作从过去某时开始，一直延续到现在。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。I have been reading Hemingway's Farewell t Arms recently.我最近一直在读海明威的《永别了，武器》。She has been reciting the wrds all the mrning.她整个上午都在背单词。This is what I have been expecting since my childhd.这是我从小以来就一直期待着的事情。
②表示动作刚刚结束My clthes are all wet. I've been wrking in the rain.我的衣服全湿了。我刚才一直在雨中干活。He is dead drunk. He's been drinking with his friends.他烂醉如泥。他刚才一直在和朋友们喝酒。
③表示一个近期内时断时续、重复发生的动作。Yu've been saying that fr five years.这话你已经说了五年了。He has been writing articles t the newspapers and magazines since he became a teacher.自从任教以来，他一直在为报刊杂志撰稿。
④表达较重的感情色彩。What have yu been ding t my dictinary?看你把我的字典弄成什么样子了？Time has been flying s quickly!时间过得可真快啊！T much has been happening tday.今天可真是个多事的日子。
3．现在完成进行时和现在完成时的比较①现在完成进行时可以表示动作的重复，而现在完成时一般不表示重复性。Have yu been meeting him recently?你最近常和他见面吗？Have yu met him recently?你最近见到过他吗？
②现在完成进行时有时含有感情色彩，而现在完成时一般是平铺直叙。I have been waiting fr yu fr tw hurs.我一直等了你两个小时。(可能表示不满)I have waited fr yu fr tw hurs.我等了你两个小时。(说明一个事实)
③现在完成进行时强调动作，而现在完成时强调结果。Wh has been eating the ranges?谁一直在吃这些桔子呀？(还剩余一些)Wh has eaten the ranges?谁把桔子吃光了？(强调吃得一个不剩)
