Basketball was invented by a Canadian doctor named James Naismith,who was born in 1861.When he was at college,his class was once asked to invent a new game that could be played indoors during the long winters.Dr Naismith created a game to be played on a hard wooden floor,so the safety of the players was important.Knocking into players and falling down would be dangerous.
Dr Naismith divided the men in his class into two teams and taught them how to play his new game.The aim of basketball is for players to get a ball into the "basket";a new hanging from a metal hoop.Plays shoot from below the basket and may use the "backboard" for guiding the ball into the basket.Players move towards one end of the court while throwing the ball to each other.
It is believed that on December 21st,1891,the first basketball game in history was played.Then in 1936 in Berlin,it became an event at the Olympic.
