MODALS OF OBLIGATION QUIZ | Mustn’t or Don’t have to / Doesn’t have to

Modals of Obligation
We can use modals to express obligation. An obligation is a necessity, or something you have to do. You must remember your partner’s birthday. Remember last year when you forgot? Yeah, you really don’t want that to happen again… When you have no choice in the matter, you can use the modals must or have to in order to express this. We can use each of them in a slightly different way.
