Dear Tom,
 Thanks for your letter, i was really happy to hear that your school team won in footbal match, it's amazing!
As for my country, there are many different kinds of sport, but i think the most popular are hockey and volleyball. I prefer watching volleyball to watching hockey because  i think volleyball is more impressive game, so i can get lots of various emotions when i watch it. Also i play such kind of sport as tennis, because it helps to keep feet and developes my muscules. 
Glad to hear that you got a new computer game. By the way, how much does it cost? Is it interesting to play? What is the main hero of this game?
that's all from me. Please write back soon.
                                                                                      Love,
                                                                                                        (Твое имя)
