been是be的过去分词，是的意思。been用在完成时和被动句中，完成时包括现在完成时和过去完成时。现在完成回时的构成是has/have+been/done，过去完成时的构答成是had+been/done；被动句的主语如果是物，那就用被动语态。

He has came back for 2 mintues。 He has been came back for 2 mintues。这两句话都是错的。与一段时间连用，要用持续性动词。应改为：he has been back。
have been doing 表动作一直进行到现在 havebeen done现在完成时的被动语态。
注意：
have been 与表示职业的名词连用，用来询问或说明某人所从事的职业。与 how long, for 或 since 等短语连用后，则表示此种状态的持续时间。
例如： Have you ever been a worker ? 你曾经当过工人吗？
I've been a teacher before . 以前我曾经是一位老师。
How long have you been a dirver ? 你当司机有多久了？
