Grammar
Let’s look at must/have to.
Look at these sentences:
We have a new art teacher. We have to do our homework. The exhibition is fantastic. You must see it! |
Look at the rules:
1 We use have to when we are talking about something that is necessary/very important to do.
2 We use must when we are obliged (we have no choice) to do something.
3 You can use must or have to when you think something is necessary especially if you are saying what you think.
4 Use must when it is a fact, or when you are not giving your opinion.
Do the exercise.
You can check out the theory of must/have to in the Grammar Desk.
