Dear Editor，
I'm the boy student in a key middle school in our city. I fond of play the piano. It is known by us that the college entrance examination is approaching. I must get good prepared for it. So I have only fifteen minutes to play the piano on every day. I don't want to give up my favorite, and my parents forbade me to continue playing it. They think it a waste of time to do it now. How do you think of it? Could you give me some advices on how to deal with the problem? I am looking forward to your early reply.
Thank you.
John
