have been和be been是一个意思吗?

have been和be been是一个意思吗? had been和havev been中为什么要加been?在现在完成时（have been）和过去完成时(had been)通常会有一个been出现,been是be 的过去分词,have和had是助动词,问：这里有助动词了为什么还要用been?这两种时态 have been doing 和 be being done 感觉是一个意思啊 have been=be have been done 和 to be done might be和 may have been的区别?还有是might do和 may have done have since been 和 have been since have been 和have ever been区别! have dead和have been dead是一个意思吗?如题!还有具体给讲讲have been dead 中为什么要用been dead? have been 和 has been的区别 has been和have been区别 关于been的一个疑惑The house has been built 10 years ago by him . 这房子是他10年前建造的（实际上是被他建造的）. I have been very busy the last few days 这里的been 是 be动词 的过去分词形式, 和上面的 have bee also would be,would also be和would be also有什么区别?类似的还有“always have been”,have always been以及have been always. have been in 和have gone to是不是一个意思?我问的是have been in 和have gone to,不是have been to 和have gone to ． I have been there,have been 是have been in还是have been to的缩写? have been + 形容词 和be+形容词 有什么区别? may have been和may be怎么翻译 have been done和be done的区别
