阅读理解 I am a schoolboy. I have lessons from Monday to Friday. On Sunday morning, I usually get up very late. I wash my face and then go out to do morning exercises. It is about nine o'clock. After I eat my breakfast. I often go to the park with my parents. The park is not far ( 远 ) from our home, so we go there by bike. It takes us about ten minutes to get there by bike. There are many people in the park. They are men and women, old and young. Parents must look after their children. There is a big lake in the middle of the park. Some children are swimming, some are boating with their parents. I like boating very much. I want to boat, too. My parents buy three tickets. We have a good time there. How happy we are! ( )3. On Sundays, there are _______ people in the park.
