I have to get up early in the morning.
I have to make breakfast.
I have to go to bed at 10 p.m.
I have to learn poem by heart.
I have to come to school tomorrow.
I don't have to get up early in the morning.
I don't have to make breakfast.
I don't have to go to bed at 10 p.m.
I don't have to learn the poem by heart.
I don't have to come to school tomorrow.
