have/has been done 是现在完成的被动语态
但He has been there for six months .这个句中的has been 与前面所说的现在完成时的被动有关系吗?

这个句式用了主系表结构
eg . He is there . 他在这, is 是be 的一般现在时.
He was there a moment ago . 他刚才在这. was 是 be 的过去时.
He has been here for six months . 他在这六个月了. has been 是be 的完成时.
助动词不能单独作谓语 ,要和主要动词一起构成谓语 ,
完成时的构成是助动词 have + 动词的过去词 , 那么 be 的过去分词是 been , 所以就出现了 have /has been 这个结构.
如果是被动的话
He has been influenced by this ideas for years.
have/has + been + 过去分词这才是完成时的被动语态

have/has been done 是现在完成的被动语态 have been done 什么东西?have been doing是现在完成进行时的被动语态嘛? 完成时被动语态为什么是have been done 问下被动语态问题,have been done 是现在完成时的被动语态,那we have done this homew have been done 是被动语态 have sth done 也是被动语态我有点蒙了. 现在完成进行时的被动语态结构是have been +过去分词还是have been+doing 有没有完成进行时的被动语态have been being done的? 被动语态be done中 be是什么词性?还有现在完成时的被动语态have been done 中have been是什 have been done除了表示完成时被动语态外,可以表示其他的么?比如I have been done中的been must have been done是什么被动语态 have done和 have been的区分有些情况写 have been未必是被动语态啊现在完成被动进行时是否是：have been being done,请给例句并说明
