My hobby is playing basketball.
There are so many reasons why I like it.For one thing,playing basketball does much benifit to my body.For another thing,it can make me feel relaxed after doing my homework.
I do usually watch basketball games.I can still remember the last year's NBA final game between Lakers ang Celtics.In my opinion,Kobe really did his best to help his team to beat Celtics.
I think I would continue to play basketball,for basketball is my favourite sport.
