List do cioci (50 - 100 słów)

Dobry wieczór, czy ktoś mógłby sprawdzić mój tekst? :)

Dear Auntie,
I would like to thank you for the birthday present which you had send me. It is really great. Last Monday, a school sports day took place. I had fun. I participated in a cycling race and in long-distance running. I was in the lead at first, but then I lost both races. My results weren't very bad, however I will focus on these two disciplines - I mean cycling and running - so that my results will be much better next year. Practice makes perfect, doesn't it? Take care, Auntie and thank you once again.
