1. I haven't to do homework every day, only on Mondays and Tuesdays.

3. My brother haven't to come home before 11 p.m., but I do.
4. When they're seventeen, english students only have to study four subjects. They're lucky!
5. We haven't got a car, so my dad have to go to work by bus.

7. I have to clean my bedroom every Saturday. I hate it!
