has been,had already,already 这三个字有什么分别?
都是 '已经' 的意思

have/has been 单独用是表示去过某地,例：I have been to Beijing.
有时也表示现在完成时,例：The movie has been on for five minutes.
在这句话中,表示电影开始应用start或begin,但由于这两个词都是非延续性动词,因此,表示一段时间,就要用be on再加时间段.
had already 是表示过去完成时,有时already可以省略,也可以放在句尾,例：My friend told me,he had (already) finished his home work.
already是形容词“已经”的意思,例：I'm already there.
总之,以上词汇中,只有already是一直表示“已经”的意思的,而另两个需要根据语境来判断.
