People all over the world are fond of sports and games.Sport makes people healthy, keeps them fit, more organized and better disciplined.It unites people of different classes and nationalities. Many people do sports on their personal initiative. They go in for skiing, skating, table tennis, swimming, volley-ball, football, body-building, etc.All necessary facilities are provided for them: stadiums, sport grounds, swimming pools, skating rinks, skiing stations, football fields.Sport is paid much attention to in our educational establishments. Gymnastics is a part of children's daily activities in the kindergartens. Physical culture is ч compulsory subject at schools and colleges.Professional sport is also paid much attention to in our country. In city, where I live, there are different sporting societies, clubs and complexes.Practically all kinds of sports are popular in our country, but football, gymnastics and tennis enjoy the greatest popularity. As for me, I go in for table tennis (ping-pong). It needs mobility, liveliness and much energy. It keeps a person in a good form. I have been playing tennis for five years, but the more I play, the more I like it. I get a real joy taking part in competitions or simply playing with my friends. Sometimes, I go to tennis courts.Certainly, there's a great distance between my manner of playing and such favourites as Jim Courier, Stephan Edberg, Pete Sampras, Boris Becker, Per Korda, but I do my training with great pleasure and hope to play as well as our best players do.
