You may play ping-pong but perhaps you don’t know who invented it.In fact, it started when two students at Cambridge University began knocking a cork(软木)to each other acro a table, which was made of old boxes.In about the year 1800, an American busineman created a game that he called indoor tennis.The Americans showed no interest in it.He introduced it to Londoners and it soon became popular in Britain.The game was then played acro dining room tables, or on the floor with the net strung between chairs.The players used a ball game made of cork or rubber.A few years later an empty ball like the one we use today was invented.People all over the world loved it at once.A man called Mr.Wood of London, had the idea of covering the bats with rubber.The London busineman who first sold the patent right(专利权)of the game in England now called it “ping-pong.” “Ping” meant the sound of the bat hitting the ball, and “pong” was the sound of the ball hitting the table.()1.Who invented table tennis first?
