    Today is Sunday. We don't go to school. So after breakfast I go to the park with some of my good friends. In the park, there are many people. They are doing exercise. Some women are dancing. Some people are playing badminton. Some girls are skipping, and some people are walking and running. Why do they work so hard? Because they want to be strong and healthy.
