     Most of us may play ping-pong, but perhaps you don't know who invented it. The story is that it started

when two students at Cambridge University began knocking a cork (软木塞) to each other across a table,

using old boxes. In about the year l,800 an American businessman of sports goods produced a game that he

called Indoor Tennis. The Americans didn't find interest in it. He shipped (海运) it to London and it soon

became popular in Britain. The game was then played across dinning room tables, or on the floor with the

net string (网) between chairs. The players used a ball made of cork or rubber. A few years later a hollow

(空的) ball like the one we use today was invented. People all over the world loved it at once. A man called

Mr Wood in London, had the idea of covering the bats (拍子) with rubber. Later a London businessman

called this game "ping-pong". "Ping" meant the sound of the bat hitting the ball, and "pong" was the sound

of the ball hitting the table.

     The game is played everywhere, but not everybody likes it. Some even think it's a silly game.
