题型描述: 阅读理解Basketball is perhaps the only sport whose exact origin can safely be stated. During the winter of 1891—1892, Dr. James Naismith, a college instructor in Springfield, Massachusetts, invented the game of basketball in order to provide exercise for the students between the closing of the football season and the opening of the baseball season. He attached fruit baskets overhead on the wall at opposite ends of the gymnasium. He organized nine-man teams to play his new game, using a soccer ball. What the players did was to throw the ball into one basket and keep the other team from tossing the ball into the opposite basket. There have since been many changes in the rules. For example, the number of players on a team has been reduced to 5. But the game is basically the same today. Americans introduced it to the Philippines in 1900 and to Europe during World War I. Being adopted by foreign countries, it soon became a worldwide sport.
