Dear Tom,
I’m an Australian boy of 16 years old, which lives in Sydney. I like Chinese very much, but I want a pen pal in China. At school I like playing football and tennis. Our favorite subject is science because it’s very interesting. I won’t like history, for I think it’s rather boring. I play guitar well, so I join in the school rock band. In the afternoon we usually play football or tennis. We usually got home at about 5:30 pm. For weekends I often go out for a swim, which is really relaxed. Do you like sports and games? What do you like to play?
I’m looking forward to get your early reply.
Yours truly,
Jack
