【正文】 nery. The price, which is the wage that employers must pay, increases. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage. Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions. 62.

For questions 810,plete the sentences with information given in the passage. Will We Run Out of Water? Picture a “ghost ship” sinking into the sand, left to rot on dry land by a receding sea. Then imagine dust storms sweeping up toxic pesticides and chemical fertilizers from the dry seabed and spewing them across towns and villages. Seem like a scene from a movie about the end of the world? For people living near the Aral sea (咸海) in Central Asia, it’s all too real. Thirty years ago, government planners diverted the rivers that flow into the sea in order to irrigate (provide water for ) farmland. As a result, the sea has shrunk to half its original size, stranding (使擱淺) ships on dry land. The seawater has tripled in salt content and bee polluted, killing all 24 native species of fish. Similar largescale efforts to redirect water in other parts of the world have also ended in ecological crisis, according to numerous environmental groups. But many countries continue to build massive dams and irrigation systems, even though such projects can create more problems than they fix. Why? People in many parts of the world are desperate for water, and more people will need more water in the next century. “Growing populations will worsen problems with water,” says Peter , an environmental scientist at the Pacific Institute for studies in Development, Environment, and Security, a research organization in California. He fears that by the year 2025, as many as onethird of the world’s projected (預(yù)測的) billion people will suffer from water shortages. WHERE WATER GOES Only percent of all water on Earth is freshwater, water suitable for drinking and growing food, says Sandra Postel, director of the Global Water Policy Project in Amherst, Mass. Twothirds of this freshwater is locked in glaciers (冰山) and ice caps (冰蓋). In fact, only a tiny percentage of freshwater is part of the water cycle, in which water evaporates and rises into the atmosphere, then condenses and falls back to Earth as precipitation (rain or snow). Some precipitation runs off land to lakes and oceans, and some bees groundwater, water that seeps into the earth. Much of this renewable freshwater ends up in remote places like the Amazon river basin in Brazil, where few people live. In fact, the world’s population has access to only 12,500 cubic kilometers of freshwater—about the amount of water in Lake Superior(蘇必利爾湖). And people use half of this amount already. “If water demand continues to climb rapidly,” says Postel, “there will be severe shortages and damage to the aquatic (水的) environment.” CLOSE TO HOME Water woes(災(zāi)難) may seem remote to people living in rich countries like the United States. But Americans could face serious water shortages, too especially in areas that rely on groundwater. Groundwa
