Write sentences about your life at home. Write two with mustard , two with mustn't and two with needn't .

I must help my parents.  На выбор  I must clean my flat (my room/my house) every week. I must go to bed before midnight. I must water the plants. I must walk my dog. I mustn't come back home after 9/10/11 p.m.  I mustn't listen to music too loudly.  I mustn't use my mother's computer at home.  I needn't clean my flat every day.  I needn't cook dinner.  I needn't clean the windows. I needn't wash my clothes by hand. (вручную)
