dear

thanks for your letter! how are you? i’m sorry i haven’t written for so long, i’ve been busy with my exams.

in your letter you ask me about sport competitions in my school. a lot of competitions take place in my school: football, volley-ball, running and swimming. if you want to become a member of any sport team, it’s very easy. just tell your pe teacher about your will and you are in! at school you also can attend tennis and basketball sections. as for the sections in town, you can join boxing and karate sections.

now about your sister’s birthday! where did the party take place? how many people did she invite? what presents did she get?

i’m sorry i have to finish up, my friend is waiting for me to go to the cinema. i’m looking forward to hearing from you!

best wishes,
