     Basketball is a young game. In the year of 1891, a famous college was having some trouble with its boy

students. The weather was bad. They couldn't play outside. So they were unhappy. Sometimes they even got

into fights.

     Finally, some teachers asked Dr. Naisimth to invent a game so that the students might have something to

play in doors.

     Dr. Naisimth thought for a few days and invented a kind of ball game. It was a fast, exciting game with

much moving and passing of the ball. It was played between two teams. In order to make a score, the ball had

to be thrown into a basket ten feet above the floor on the wall.

     At first, Dr. Naisimth had planned to have the ball thrown into a box. As he couldn't find boxes of the right

size, he had to use fruit basket instead. That is how the game got its name basketball. The history of this game

is over 100 years.
