Hello XXXXX,

Excellent work! Your PDF is attached for you to review when you have a chance to.

For homework, try these exercises with don’t have to and mustn’t:
-https://agendaweb.org/exercises/verbs/modals/must-have-not

For some listening homework and a quiz on our key grammar topic:

For a writing homework, choose another situation. Similar to the examples on the final 3 slides of the PDF, write a short text describing how you should behave in that situation. Describe what you mustn’t/don’t have to do.

Have a good week and let me know if you have any questions or requests,
