Nowadays, have sports is becoming more and more popular. As we know, a person who keeps on taking exercise regular will keep fit and live happy life.
My favorite sport is playing basketball. After school I usually spent half an hour on it, that not only builds up my body but also makes me refreshed. Playing basketball help me relax after a period of tired study and improves my study efficiency. Besides, because playing basketball needs cooperation, so I have learned the spirit of teamwork. It is also a good way for me to make new friend. In a word, playing basketball enriches my life and makes me more confidence.
