Do You Know When Basketball
Was Invented？
Basketball is a much-loved and active sport that is enjoyed by many for fun and exercise. It is over 100 years old and is played by more than 100 million people in over 200 countries. It is believed that the first basketball game in history was played on De-cember 21, 1891. Then in 1936 in Berlin, it became an event at the Olympics.
Basketball was invented by a Canadian doctor named James Naismith, who was born in 1861. When he was a college teacher, he was asked to think of a game that could 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 class into two teams and taught them to play his new game. Players on the same team must work together to get the ball in the other team’s basket. At the same time, they need to stop the compet-ing team from getting the ball into their own basket.
Today, the popularity of basketball has risen around the world, with many young people dreaming of becoming famous players. In China, you can sometimes see people playing basketball in parks, schools and even factories. Basketball has not only become a popular sport to play, but it has also become a popular sport to watch.
Although America’s NBA games are the most famous, the CBA games are becoming more popular in China. The number of foreign players, including Chinese players, in the NBA has increased. 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.
