听力原文： Hyperinflation is defined as an economic condition during which there is a steep increase in prices. In accordance with the laws of economics, three factors combine to create this condition. First, demand must be much greater than the supply of available goods. Second, the country must continuously create and thereby build up an ever-increasing supply of money. Third, the governmental processes that are used to collect taxes must be crippled. Let's imagine a country where production is barely accomplishing its goal: to keep up with demand. When this happens, the government should decrease the salaries of the workers by raising taxes. But the government is powerless to collect the taxes, so it prints more money to compensate for the goods it must purchase. This new money goes to the workers who produced the goods; as a result, the people are not forced to give up certain things for a while—they actually become richer. While this might appear to be a positive step, it is actually regressive. Every month the government is forced to print more and more money, thereby increasing its liabilities until, it is destroyed. The only way to prevent total economic collapse in such a situation is for the government to increase taxes in a manner that is characterized by impartiality to everyone involved.
