have to or can
I have to plant flowers. I can swim everyday. We can't eat some apples. Did you blow any air. Did she see a child. Were you burnt ? Did she give me any bread ? Does he use any wood ? We have to drink some coffe. I can refuel gasoline. I can't watch the TV show You don't have to begin new work. She can drink a cup coffe. I have to recover.
Great!
