假设你叫李明，是美国中学生Tom的笔友。请您根据他给你的电子邮件内容写一封回信。谈谈你的个人爱好情况及你对个人爱好的看法。
Dear Li Ming,
I’d like to know what your hobby is. Do you spend much time on it?
My favorite hobby is collecting stamps. I’ve got a wonderful collection of them now. My father bought me the first stamp-album (集邮簿) when I was ten years old. I began to collect stamps from then on. It has brought me great enjoyment but it takes me a lot of time. Sometimes I forget to do my schoolwork. My mother wants me to stop it because she thinks it bad for my study. What do you think about it?
Yours,
Tom
 
Hi Tom,
