have been和be been是一个意思吗?

have dead和have been dead是一个意思吗? have been doing 和 be being done 感觉是一个意思啊 have already been重复吗?have been的意思不就是 已经被...他和have already be have been in 和have gone to是不是一个意思? have been=be have/had + been/be? Have been Be Have been 和 Be 的分别 have been done 和 to be done there be 和 there has/have been 在英语里coms been、must been和may been和come have been、must have be had done 是过去完成时,have done是现在完成时,那have been和had been呢?be不是动词呀
