     My name is Tony and I live in Canada. My mother is from Korea (朝鲜) and my father is from France, so we speak three languages at home. I think languages are very interesting and I want to study Portuguese and Chinese. But my favorite subject at school isn't language. It's math. I really like history, too.

     I like sports, especially (尤其) soccer and basketball, because they are relaxing. But I don't have

much time to play them. I go to music club after school on Mondays, I have guitar lessons on Wednesdays, and go to library on Fridays. But Saturdays and Sundays are great because I can play sports, sleep

(睡觉),

and watch TV.
