1. 现在完成进行时的概念
2. 现在完成时的形式
have / has been doing
Grammar: Present perfect continuous
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 solar racing cars.
我一直在设计太阳能赛车。
b. I have designed five or six different cars.
我已经设计五六辆小汽车了。
Grammar: Present perfect continuous

我这四年一直在参加比赛。
b. How many races have you taken part in
你参加多少场比赛了？
Grammar: Present perfect continuous
3. 现在完成时和现在完成进行时的区别
3）现在完成进行时与所有进行时态一样带有感彩，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，不带感彩。
例如：
What have you been doing You looked fed up.
你一直在干什么呀？你看上去很不高兴。
Grammar: Present perfect continuous
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, for … , since … 等。例如：
