e.g. I will tell you something important. 我要告诉你一些重要的事。
（助动词）

We had to be there at 10:00. 有时两者都可以用, 意思差别不大。
e. g.
We must/have to leave now. must在表示说话人对事物的推测时 候要注意它比may肯定得多, 相当于 汉语的“一定”或“准是”。(只有 在肯定句中能这样用。)
There may be some dangerous animals on the island.
4.should（想必）
They should be there by now.
5.如果对过去发生的事情的推测 要用完成时。
