其实must have been done只是must have done的被动形式罢了.
我说,你举出来的那几个例子：1那个就是must have been doing的结构是指某动作在过去某时间点开始,一直持续到现在,有继续持续下去的趋向,或者等这句话一说完这个动作就完成；
2那个是加形容词 be expensive=很贵,must have been expensive= 一定是很贵的了.
3那个asleep也是形容词,be asleep=睡着的.句子意思是：那时我一定是睡着了.（表示对过去肯定的推测）

must have done是对过去事实的肯定猜测 而must have been doing 表示某人一定正在做某事 这个动作从过去持续到现在 must have been就是表示一个肯定的结果

must have been done must have done must have/ must have been的区别 must not have been;could not have must have been与must have done的区别? It Must Have Been Love (Cologne) 歌词 请问：有没有must have been? It Must Have Been Love 歌词 must have been done/must be done求解两者异同 must be和must have been有什么区别he must have been sleeping.为什么这里要用must have been而不用must be be,must be,can't have been,must have been吗 must have been doing与must have been done都表示推测,有什么区别呀? must have been请问 must have been 是推测某人一直在做某事吗? i think he must have been a mechanic,中的must和have been是什么词啊? may have been和 must have been been是不是不仅表示被动?
