must have do 句型,比如when i suggested that some villagers must have come in for free drink这里为什么用must have come啊?不用过去式吗?这是什么句型这句话?

只有must have done ,句子中的must have come 里的come是过去分词
must have done,表示一定做了.对过去的事情进行推测
比如：He must have left.他一定已经离开了.
You must have told him the secret.你一定告诉了他这个秘密.
再问：这句话可以说must come in for free drink吗？可以不加have吗？
再答： must do 的意思是，必需做... 或者一定要做，并不能对过去进行推测。改了后意思肯定变了。

must have do 句型,比如when i suggested that some villagers must When I suggested that some villagers must have come in for a I suggested that some villagers must have come in for a free there must have句型? have to 和must 的区别是什么记住,一定要直观,比如是 I must还是have to do my homew You must write on every___line,so that i can do some correct but i must tell you that it is like road which do not have i I have quite a lot of homework to do.I must finish that firs must have done 和must have do must＋have done 句型 what must i do? 翻译：You must do everything that I do.
