Tom: My favourite after-school activity is - playing sports! I took up tennis when I was 10 and now I go to a tennis club twice a week. Besides, I am mad about football. I'm in the school football team and we play against other schools every Tuesday. It's so thrilling to take part in football competitions and to win them! I also want to try something challenging, skateboarding for example. In the evening I usually watch TV, play computer games or read. I can't say that I read a lot, but I'm fond of funny stories.

Linda: Homework takes most of my free time on weekdays. If I am not doing my homework, I prefer listening to music. For me there is nothing more enjoyable and relaxing than listening to my favourite songs and joining in singing. At weekends I usually hang out with my friends in the park. Sometimes I go sightseeing with the history club. It's an exciting change from school and homework!

Robert: I am keen on collecting. I've got different collections. At primary school I collected car models, stickers of pop stars and sportsmen. Now I'm collecting stamps and coins from different countries. I don't understand why some children start collecting something and very soon give up this hobby. I think collecting is a fun and interesting hobby. I get a lot out of it. I keep a diary (дневник) and write interesting facts about each item of my collection. I often show my collections at our school club of collectors.
