英语的现在进行完成时态是怎么构成的?have being done 还是have been doing? have been done 什么东西?have been doing是现在完成进行时的被动语态嘛? have been doing和have been done哪个是现在完成进行时啊? 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 英语完成时态的构成请问英语完成进行时态的构成为什么不是have,has加现在分词呢?为什么要加been呢? 现在完成被动进行时是否是：have been being done,请给例句并说明 有没有完成进行时的被动语态have been being done的? have/has been done 是现在完成的被动语态 [现在进行完成时]一直和你在一起：have been with you 还是 have been being with 英语时态区分have done .have been doing.had done.had been doing.有什么 BE BEING DOING/BE BEING DONE/HAVE BEEN DONE 现在完成进行时不是由“助动词have(has) + been+动词的现在分词”构成的吗 那having done是什么啊
