听力原文： Some people dream of being president of the United States, some of becoming stars in a Hollywood movie, and others of making millions of dollars overnight. Could a dream like that come true in real life？ Well, it did happen to Peter Johnson. Peter was an auto mechanic. One day, he walked into the Union Trust Bank in Waltermore and took ＄5,000 that did not belong to him. The guards and other employees stood back and let him stuff the bills into his shirt and pants without trying to prevent him from taking the money. No one pressed the alarm. No one pulled the gun. No one called the police. Why did they allow him to get away with it？ Well, everything was legal. Peter had won a contest promoted by a Waltermore radio station. The first prize entitled him to enter the Union Trust Bank to gather up as much money as he could lay his hands on within five minutes. Because he could not bring any large sacks or boxes into the bank, all the money had to be placed in his pockets. As the time went by, Peter ran about wildly and tried to pick up as many large bills as he could find. When his time was up, he was out of breath, but was ＄5,000 richer.
