Do You Know When Basketball Was Invented?
Basketball is a much-loved and active sport more than 100 million people in over 200 countries.In China, you can
sometimes see people playing basketball in parks, schools and even in factories.Basketball was invented by a Canadian doctor named
James Naismith, who was born in 1861.When he was at college, his teacher asked the cla to think of a game that can be played in the winter.Dr.Naismith created a game to be played inside on a hard floor.Dr.Naismith divided the men in his cla into two teams and taught them to play his new game.The purpose of the game is for players to get a ball into the “basket”.Players on the same team must work together to help each other get
the ball in the other team’s basket.At the same time, they need to stop the competing team from getting the ball into their own basket.It is believed that on December 21, 1891, the fi rst
basketball game in history was played.Then in 1936 in Berlin, it became an event at the Olympics.Today, the popularity of
basketball has risen around the world, with many young people dreaming of becoming famous players.Basketball has not only become a popular sport to play, it has also become a more
popular sport to watch.Although America’s NBA games are the most famous,the CBA games are becoming popular in China.The number of
foreign players, including Chinese players, in the NBA has
increased.And there are also more and more foreign players in the CBA.Many young people look up to these basketball heroes and want to become like them.These stars encourage young people to work hard to achieve their dreams.
