     My name is Tony and my family live in Canada. My mother is from Japan 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 (葡萄牙语) and Chinese. But my favorite subject at school is 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 I go to library on Fridays. But Saturdays and Sundays are great because I can play

 sports, sleep, and watch TV.
