have done还是be done是被动语态,

have done还是be done是被动语态, have been done 是被动语态 have sth done 也是被动语态 我有点蒙了. 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 完成时被动语态为什么是have been done have/has been done 是现在完成的被动语态 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 现在时的被动语态　be done must have been done是什么被动语态 含有be动词的被动语态怎么变,have been done一定指被动吗 done与be done,being done都表被动语态,有什么区别 must have done和must be在处于被动语态时的区别 被动语态 be done 能省略be的情况
