1 have been study 和 have been absent最常见到,既然不是被动语态（主语是人）,为什么不直接用have + 动词过去分词的形式呢?
2 have absented 我也看到过 不知道和have been absent 有什么区别（study和absebt在这都不做动词用了这我知道,我就是不知道为什么要这么用,是习惯用法吗?）
3 另外 how long has she been study与 how long has she been studying只有语境上去区别对吧,意思都是一样的,用studying强调还会继续学习下去,但是study在这也暗示会继续学习下去吧.

1. have been study 是不存在的形式,你打错了吗?只会是have been studying(现在完成进行时)或者have studied(现在完成时)
2.have been absent(现在完成时)absent在这里是形容词,不可以用作过去分词.
3. How long has she been studying?是现在完成进行时,表示从过去开始的动作一直持续到现在,而且此刻动作仍在进行中或继续进行下去.
