没有must not have done,表示对过去事情肯定的推测用must have done,否定的推测只能用can't/couldn't have done.
在反意疑问句中要根据具体的时态来定,如果句中有具体的过去时间状语的话就用did/didn't we,反之没有具体的过去时间状语,强调对现在影响时,就用完成时.
例如：He must have attended the party last night,didn't he?
He knows everything about it,so he must have read the book,hasn't he?

must not have+动词的过去分词.有没有这种用法? must not have 请问：有没有must have been? 有没有must have to 这个词? I don't have any 和 I have not any有什么不同吗?I have not any 就是I haven't any阿，有没有这种说法？ must 和must not ,have to 和not have to ,need和not need有什么区别 must not have been;could not have It's not me.I don't have a icy heart.这两句话有没有什么语法错误? must 和 have to 有什么不一样?mustn't 和 don't have有什么不一样? do you have a knife?no,i don't这句话有没有什么错?no,i don't与no,i'm not有什么区别? Must I finish copying the letter of thanks this evening?No ,you ______A don`t have to B not have to C mustn`t D may not ---Must I come at four o'clock?--No you ---.A .may not B.don't have to Nothing you must to do Others have behaved,not impose on others .So,i don't care!you know I must go to the grocer's.we have not got much tea or coffee.这里为何要用GOT ,可以去掉吗,HAVE NOT就已经有没有的意思 you must not ask someone else to do the homework for you.改have/get sth.don改have/get sth.done 关于过去式和完成时的一道题目 = =It must have rained last night ,___ it?为什么老师说有 last night 在,就要用 did not；本题若没有 last night ,就用 has not . must have been和can't have been和现在完成时有没有联系啊有没有have been doing 这个时态?must have been doing呢?
