Hello, Mr. Brown! My name is Eugene and I’m 9th grade student. I like traveling and doing some sports, so your summer camp is interesting for me.
In this summer I have a lot of time, so I can stay for 3 weeks from the beginning of July. For my opinion, at this time the weather is the best, but that’s very important for outdoor activities.
I would choose adventure workshop, because I tried diving last year and really liked it. Also I have experience in film making, so film academy workshop would be interesting for me. I could help another children and learn something new.
Best regards,
Eugene.

Итак, начнём!

Hello, Mr. Brown!

My name is Eugene and I’m a 9th grader. I enjoy traveling and playing several sports, because of that I am interested in your summer camp.

This summer I’ll have lots of time on hand, and would like to participate for 3 weeks starting early July. In my opinion, that’s when the weather is best, which it’s highly important for outdoor activities.

I would love to do the adventure workshop, I’ve tried diving last year and really liked it. Also I have some experience in film making, so the film academy workshop sounds quite interesting. I look forward to helping other campers and learning new things .

Best regards,

Eugene.
