Once, a man got on a bus to New York. Because he did not want to pay, so he hid in the toilet. But a passenger saw her. She tapped the person in front of her on the shoulder and say, “There’s a bum (流浪汉) in the toilet. Tell the bus driver.” The message was passing on from person to person. But somewhere along the way, it was changed. The bus driver told that there was a bomb in the toilet. He immediate stopped the bus and telephoned the police. Before the police came, they told the passengers to get into the bus and stay far away. Then they closed the highway, as a result of whom a 15-mile-long traffic jam was soon caused. With the help of the dog, the police searched for two hours. Of course they found no bomb.

Background music may seem harmless, but it can have a powerful effect on those who hear it. Recorded background music first found its way into factories, shops and restaurants in the USA. Very soon it spread to other parts of the world. Now it is becoming difficult to go shopping or eat a meal without listening to background music.

　　To begin with, background music was intended simply to create a soothing (舒适的) atmosphere. Recently, however, it's becoming a big business. An American marketing expert has shown that music can boost(提升) sales or increase factory production by as much as a third.

　　But it has to be the light music. Lively music has no effect at all on sales. Slow music can increase receipts(收入) by 34%. This is probably because shoppers slow down and have more opportunity to spot items they would like to buy. Yet, slow music isn't always the answer. The expert found that in restaurants slow music meant customers took longer to eat their meals, which reduced overall sales. So restaurant owners might be well advised to play faster music to keep the customers moving-unless, of course, the resulting indigestion(消化不良) leads to complaints.
