A grammar quiz to revise modal verbs of obligation in a fill in the blanks exercise. The answers are provided with explanations in the feedback notes for your convenience. 

What's covered?

Both must and have to are used in talking about obligations. Their differences are very subtle and mostly interchangeable. This worksheet covers the following uses of must and have/has to. On the other hand, the negative forms of must and have to are pretty straightforward and easy to teach in proper contexts. It's also important to take the point of view into account, which makes possible multiple answers in some questions. They are also explained in the feedback notes. 

Here are the covered uses:

  • Internal obligations
  • In external obligations
  • The lack of an obligation
  • Strong advice
  • Prohibitions
