1. Which of these statements are true about sentence (a)
(1) Wild animals started using these passages in the past.
(2) Wild animals used these passages only once.
(3) Wild animals still use these passages now.
2. What is the difference between the expressions in bold in sentences (a) and (b)
They are different in form and meaning. For sentence (a) the form is “have been doing” , while for sentence (b) the form is “have done”. In meaning, the bold part in sentence (a) means the action is continuous from the past; while the bold part in sentence (b) means the action happened once in the past.

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。
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
3. 现在完成时和现在完成进行时的区别
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。

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。
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。
