阅读短文判断对错。 Let's play ball! Around the world people play many different ball games.It is not certain how these games were created,but we do know the history of two of them. Basketball started in the United States,but was created by a Canadian,James Naismith,in 1891.While teaching P.E.at Springfield College in Massachusetts,Naismith gotthe idea for the game.During the winter,students could rarely exercise outdoors.Seeingthis,Naismith got two large baskets and hang them on opposite walls of the school gym,about three meters above the floor.He divided the students into two teams.The object of the game was to throw a ball into the basket.Players soon got tired of getting the ball out of the baskets,so Naismith cut holes in the bottoms of them.Many people liked the game and,in 1936,basketball became an Olympic sport. In 1895,William G.Morgan,a teacher at the Young Men's Christian Association in Masachusetts, created a new game for his students. Morgan began with a tennis net. He raised the top of the net two meters above the floor.Players hit a large ball over the net using their hands and wrists.Like tennis,players had to hit the ball so it landed on the other side of the net inside the court lines,and not drop it.In 1896,the first game of volleyball was played at Springfield College.This game also became very well-liked and by 1905,it was played in Canada,Asia,and Cuba. In 1964, volleyball also became an Olympic sport.
