现在完成进行时表示动作从过去某一时间开始一直持续到现在，这个动作可能终止，也可能还在进行。
1. 现在完成进行时的概念
2. 现在完成时的形式
have / has been ding
3. 现在完成时和现在完成进行时的区别
1）在不用时间状语的情况下，现在完成进行时的动作不一定已经完成，很可能持续下去， 而现在完成时一般表示动作已经完成。即现在完成进行时强调动作的延续性，而现在完成时强调动作的结果。例如：
a. I have been designing slar racing cars. 我一直在设计太阳能赛车。b. I have designed five r six different cars. 我已经设计五六辆小汽车了。
2）现在完成进行时往往表示动作在重复，而现在完成时一般不表示动作的重复。例如：
a. I have been taking part in races fr fur years. 我这四年一直在参加比赛。b. Hw many races have yu taken part in? 你参加多少场比赛了？
3）现在完成进行时与所有进行时态一样带有感情色彩，可使表达显得生动，而现在完成时往往只表明一个事实、一种影响或结果，不带感情色彩。例如：
What have yu been ding? Yu lked fed up.你一直在干什么呀？你看上去很不高兴。
4. 常与现在完成进行时连用的时间状语
现在完成进行时常与表示一段时间的状语连用，例如：all the time, this week, all night, these few days, fr … , since … 等。例如：
a. A private detective has been tailing him fr several weeks. 一个私人侦探几个星期以来一直在跟踪他。b. Craig lves utdr activities — he skis in winter and has been fishing and hunting since he was a child. Craig 热爱户外活动。冬天他去滑雪，他从小就开始 钓鱼和打猎。
