(2) Wild animals used these passages only once.
(3) Wild animals still use these passages now.

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.

现在完成进行时
1现在完成进行时的概念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，这个动作可能刚终止，也可能还在进行。
2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：
I've been designing solar racing cars.(我一直在设计太阳能赛车。）
b.I've designed five or 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've been taking part in races for four years. (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？）
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 look fed up. (你一直在干什么呀？你看上去很不高兴。）
3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：a. A private detective has been tailing him for several weeks. (一位私人侦探几个星期以来一直在跟踪他。)
b. Craig loves outdoor 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。）
Activity 2
I _____________________ (hear) a strange sound for a while. It's a deep, loud roar, like a lion's. But there aren't any lions here... Or are there Soon I see what 2_____________________ (make) the noise: a howler monkey. Now I feel less worried. Realising that something 3 ____________________ (move) on my shoulder, I turn my head to look at it. Oh no! It's a giant spider! I brush it off and it runs under some leaves. I try to bat away the huge insects, which 4 _____________________ (fly) around my head in a black cloud for quite a while.
