Hes been lying in bed for three weeks. 他病了，已经卧床3个星期了。Your eyes are red. Have you been crying?你眼睛红了。你刚刚哭过了吗？What have you been doing all this time?这半天你干什么来着？2现在完成进行时的用法 （B） 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 month, all night, all the morning, recently等状语以及since和for引导的状语连用。I have been reading Hemingways Farewell to Arms recently.我最近一直在读海明威的永别了，武器。表示动作刚刚结束My clothes are all wet. Ive been working in the rain.我的衣服全湿了，我刚才一直在雨中干活。表示一个近期内时断时续、重复发生的动作Youve been saying that for five years.这话你已经说了五年了。表达较重的感情色彩What have you been doing to my dictionary?看你把我的字典弄成什么样子了！3现在完成进行时和现在完成时的比较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 you been meeting him recently?你最近常和他见面吗？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 for you for two hours.我一直等了你两个小时。（可能表示不满）现在完成进行时强调动作，而现在完成时强调结果。Who has been eating the oranges?谁一直在吃这些桔子呀？（还剩余一些）Who has eaten the oranges? 谁把桔子吃光了？（强调吃得一个不剩）一，用动词的适当形式填空(分层次练习B)1 _ you _ my pen?
