I have to do my homework - musze odrabiac zadanie domowe
I must tidy my room - musze sprzatac pokoj
I don't have to feed my dog - nie musze karmic mojego psa
I have to help my mum with housework - musze pomagac mamie w pracach domowych
I must go shopping - musze chodzic na zakupy
I don't have to cook dinner - nie musze gotowac obiadu
