Hi, my name is [имя ] and today I want to tell you about my hobby. My favourite kind of sport - is swimming, and it is my hobby. I like water and all that associate with it. When I am swimming, I feel myself like fish feels itself in the water. My friends told me that I can be a great swimmer, and they compare me with a son of Neptune. As for me, it is funny, because I only do, what I want and what I like . I started going to the swimming pool [2,3,4..] years ago ,thanks to my mother, who likes watching sport channels. Once when I watched with her one swimming competition, I decided, that this kind of sport is my destination.
As for me, there is no matter, how do you do your favourite hobby, it's important, how do you love it.
