As what Voltaire said,"Life lies in healthy exercise.", for me, playing sports is not only a part of my life, but also a great teacher in my life. Among all those sports I play, swimming, table tennis and so on, I have put almost all of me passion into basketball. Playing basketball also teaches me a lot.
Sports give me a chance to imporve my team work ability and leadership. Everyone knows that basketball is a team work. If what you want is to win the whole game instead of just get the ball into the ring, you need to learn to pass the ball to your teammates. No one can win every game by himself, even Kobe. Except learning sharing balls, I have also learned how to be a leader. In a basketball game, there must ba one leader in each team. Some time, the leader is the one who play the best, and some time, the one is who knows how to put the whole teammates' heart together. Gradually being a leader on basketball court, I have understood how to ba a great leader who can leads his team to success.
Sports help to develop my ambition. Those sports with boby crash are able to easily inspire players' ambition and anger to win. Although some people think Kobe Bryant is a little bit selfish that he likes to finish the ball by himself, I have always remember what he said when I am on the court------" Remember, every game you play could probably be the last game you have ever played." Because of this, I treat every game as the last game and put the whole me into it. With the ambition in my life, I know that I need to put one hundred percent of hard working into my life and being success comes from it. 
Doing sports also taught me to be concentrated. For the first time I played basketball in a competetion in front of the whole school, I was so nervous that I couldn't even handle the ball. After the game, I was very upste and blamed myself for being a coward. I have found that I had paid too much attention on the audiences but not the game. Being concentrate to the game is a good way to relase my nervous. From that, I have learned to put all the mind into one thing.
All in all, doing sports can really teaches people a lot. And also, it can keep people healthy .
