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 1800 an American businessman of sports goods
produced a game that he called Indoor Tennis. The Americans didn't find interest in it. He shipped
(用船运) it to London and it soon became popular in Britain. The game was then played across dining
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.
