All over the world people enjoy sports. Sports help to keep people healthy, happy and help them to live longer. 

Sports change with the season. People play different games in winter and summer. Games and sports often grow out of people’s work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too. Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers. Some sports or games go back to thousands of years, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time. 

People from different countries may not be able to understand each other, but after a game they often become good friends. Sports help to train a person’s character. One learns to fight hard but fight fair, to win without pride and to lose with grace(体面)
