Dear Ben,

Thanks for your email, it is really interesting.

Oh, I envy you: it is my dream to see koalas. I admire them. And they are so entertaining! I wish I visited Australia. Besides you went surfing. It sounds captivating. Unfortunately I can’t swim at all.

Last summer I was in Sochi. I was very impressed. I liked all kinds of sport facilities they had built for Olympic Games. Some day I would like to visit the USA. I am really fond of sports. And they pay a lot of attention to it in this country. I want to learn to play golf as it is rare kind of sport in our country.

Well, I have to stop now as I am very busy with my homework. Hope to get an answer from you soon.

Best wishes,
