Must and have to

1. You apologize; it isn’t necessary.

2. You tell the boss what happened, or he’ll fire you.

3. I don’t wear a tie; I do it because I like wearing ties.

4. You smoke in here; smoking is not allowed.

5. I be late. It’s the most important meeting of the year.

6. You go now; you can stay a bit longer.

7. Visitors to the zoo feed the animals.

8. You have to drive so fast; we have a lot of time.

9. We cook more; there’s enough food.

10. You put salt in her food; the doctor said she can’t eat salt.
