21、定义 现在完成进行时表示某动作从过去某个时间开始，一直延续到现在，并且还有可能持续下去。e.g.Those cats have been screaming for hours.那些猫叫了半天了。二、现在完成进行时的结构:have/has been+现在分词 e.g.I have been waiting for an hour and a half.我一直等了一个半小时了。三、现在完成进行时主要用法 1.表示“持续”：即表示一个从过去某时开始一直持续的动作，这动作可能刚刚停止，也可能还在进行。如：e.g.The children have been having a lot of fun.孩

22、子们一直玩得很开心。e.g.She is very tired.Shes been working all morning.她很累。她干了一早晨了。2.表示“重复”学习必备 欢迎下载 即表示在一段持续的时间内动作的多次重复，而这个重复的动作在说话时并不一定在进行。e.g.Weve all along been making mistakes like this.我们一直犯这样的错误。四、与现在完成进行连用的主要时间状语 现在完成进行时所用的时间状语：all day/month;this month/week/year;these days;recently/lately;in the past

23、 few+时间段;since+时间点;for+时间段，等等。e.g.He has been working all day.他整天都在工作。They have been building the bridge for two month.两个月来他们一直在修桥。He has been sleeping for ten hours.他已经睡了十个小时了。The two parties have been trying to unite since the New Year.自从新年以来，双方就一直在试图联手。拓展：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

24、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。如：He has changed 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。如：We have been studying here for two years.我们在这儿已经学习了两年了。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。如：He has cleaned the window.他把窗户擦干净了。(动作已完成)He has been c

25、leaning the window.他一直在擦窗户。(动作不一定完成)4.有些静态动词只能用于现在完成时，一般不能用于现在完成进行时。如：The war has lasted for a long time.这场战争持续了很长时间。5.现在完成时与现在完成进行时的相通性：在表达一个从过去开始而现在仍在继续或刚刚结束的动作时，某些动词既可以用现在完成时，也可以用现在完成进行时，如 expect,hope,learn,lie,live,look,rain,sleep,sit,snow,stand,stay,study,teach,wait,want,work 等。如：学习必备 欢迎下载 你学习英
