must에는 ~ 해야 한다 라는 뜻만 있다고 생각했었다.
하지만 그 뿐만 아니라 ~이다(일것이다) 라는 뜻도 있다.
강한 확신을 가지고 있다 라는 것을 나타낸다고 보면 될것같다.
ex)
Your worked ten hours today. You must be tired.
My brother has worked at your company for years. You must know him.
과거를 표현할때는 must라고 하지 않고 had to 를 사용한다.
They were in a dangerous situation. They had to be careful.
We had to wear safety glasses when we visited the factory last week.
