## Step 6 - Grammar

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.
