5、he government .语法精析一、现在完成进行时现在完成进行时由“have/has been现在分词”构成。1现在完成进行时的用法(1)现在完成进行时表示动作从过去某一时刻开始一直延续到现在或离现在不远的时间，其动作是否继续下去，则由上下文而定。这个时态多用于延续性动词，如live，learn，lie，stay，sit，wait，stand，rest，study等，并常和all this week，this month，all night，all the morning，recently等状语以及since和for引导的时间状语连用 (与since和for连用时，动作常会继续下去)。I
6、 have been waiting for an hour and he still hasnt turned up.我已经等了一个小时了，可他还没来。Ive been writing letters all this morning.我写了一上午的信。How long have you been living here?你在这里住了多久了？(2)有时现在完成进行时所表示的动作并不是一直在不停地进行，而是在断断续续地重复。这时现在完成进行时可用于瞬间动词。Hes been shaving since last year.他是从去年开始刮脸的。You have been saying for
7、a year that you will study abroad.整整一年你都在说要出国学习。2现在完成进行时中时间状语的省略现在完成进行时在上下文清楚时亦可不用时间状语。这种现在完成进行时多指“刚才”或“近来”发生的动作，一般不再继续，并往往含有一种直接的结果。Youve been working too hard.你工作太辛苦了。(直接结果可能是你一定很累了)Youve been smoking again.你又抽烟了。(暗含结果你身上有烟味)Whos been insulting you?谁欺负你了？(对方可能在哭)3现在完成进行时的感情色彩现在完成进行时和其他进行时态一样，也可以带有
8、感情色彩。I have been wanting to meet you for a long time.和你见面是我盼望已久的事。Too much has been happening today.今天发生太多事了。二、现在完成时与现在完成进行时现在完成进行时是兼有现在完成时和现在进行时二者基本特点的时态。由于它有现在完成时的特点，所以它可以表示某一动作对现在产生的结果或影响；由于它有现在进行时的特点，所以它也可以表示某一动作的延续性、临时性、重复性、生动性乃至感情色彩。现在完成时和现在完成进行时的比较：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 you be
9、en meeting him recently?你最近常和他见面吗？Have you met him recently?你最近见过他吗？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 for you for two hours.我一直等了你两个小时。(可能表示不满)I have waited for you for two hours.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。Who has been eating the oranges?谁一直在吃橘子呀？(还剩余一些)Who has eaten t
10、he oranges?谁把橘子吃了？(强调吃得一个不剩)4有些动词不能用于现在完成进行时，但可用于现在完成时。如：表示状态的动词：be，have，exist等；表示感情的动词：like，love等；表示感觉的动词：see，hear，know等。He has had a cold for a week.他已经感冒一周了。I have liked jazz since I was a teenager.从青少年起我就喜欢爵士乐了。I have known her for a long time.我认识她已经很长时间了。5与一段时间连用时可以用现在完成时也可以用现在完成进行时；但与次数连用时只能用现
11、在完成时，不能用现在完成进行时。6这两种时态都可以表示动作的延续，区别在于：现在完成进行时更强调动作的延续性，可以说是现在完成时的强调形式。We have been living here for ten years.We have lived here for ten years.我们在这里住了十年了。7在没有时间状语的情况下，现在完成进行时表示动作仍在进行，而现在完成时则表示动作到现在已经结束。The students have been preparing for the exam.学生们一直在为考试做准备。(还在进行)The students have prepared for the
12、 exam.学生们为考试做了准备。(已经结束)题组训练用所给动词的正确形式填空1In order to find the missing child，villagers (do) all they can over the past five hours.2Alvin，are you coming with us?Id love to，but something unexpected (come) up.3I remember you were a talented pianist at college.Can you play the piano for me?Sorry，I (not，pl
