    My favorite sport is football. I was a member of our school football team. We practise for three times

every week and often watch football match on TV together. Play football not only makes us grow up tall

and strong but also give us a sense of fair play and team spirit. We must keep in minds that we play for

the team instead ourselves. Also sport teaches us the important of obedience (服从). Each player must

obey the captain, which is the leader of the team. And they must not break the rules too often if we want

to win the game.
