Sport is very popular among people in all the countries of the world. 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, volleyball, football, basketball, body-building etc.
All necessary facilities are provided for them: stadiums, sport swimming-pools, skating-rinks, football fields. But, of course, one have to pay for these services.
Sport is paid much attention to in our schools and colleges. Physical training is a compulsory subject. Different sports and games are popular with my classmates. All my friends go in for different kinds of sport, such as water sports (that is swimming, sailing, rowing), gymnastics, horse-racing, wrestling, fencing, weightlifting, boxing, football, basketball, volleyball, etc.
Physical training lessons at our school were held out-of-doors in summer. When it was cold outside the lessons were held indoors in our school gymnasium.
Professional sport is also paid much attention to in our country. There are different sport societies, clubs and sport schools in our town. Practically all kinds of sports are popular in our country, but gymnastics and tennis enjoy the greatest popularity.
The most popular kinds of sports in the United States are baseball, basketball and American football. In England popular kinds of sports are golf and rugby. Englishmen like football too. It is their national kind of sports.
