Unit 5 The power of nature .阅读理解 (2018河北衡水中学第四次检测)Water supplies around the world are running dry.Scientists say the world is experiencing a shortage of fresh water.It will only worsen as the population grows fast and the climate changes.People living in the western part of the U.S.are experiencing this now.For several years,there hasnt been much water.But the American West is not the only place thirsty for water.Jerry Schubel,president and CEO of the Aquarium of the Pacific in Long Beach,California,said,“More than half of the worlds population lives in water-stressed areas and according to the United Nations,that number will increase to two-thirds by 2025,fewer than 10 years from now.The amount of water on the earth has not changed for billions of years,but the ratio (比率) of fresh to salt water has.There are also other factors that are creating a fresh water shortage.In many parts of the world,shortage of fresh water is a looming (隐隐显现的) crisis that will become more serious by climate change and a growing population.Most of the worlds population lives in countries that share bodies of water.Many of those countries dont reach an agreement on how to share that water.”Scientists think conservation is the most important step in solving the water crisis.Kevin Wattier,manager of the Long Beach water department,said desalinating removing salt from sea water is also an option.But that comes at a price.“It would cost at least twice or three times as much to desalinate sea water as it would cost to buy imported water.You will increase your global carbon footprint when you go to sea water desalination.”Jerry Schubel thought the problem of global water shortage can be solved only if countries work together.“We could supply everyone on this planet with safe drinking water and enough water to grow their food.But it needs money,technology,political will and cooperation.And learning how to share requires collaborative (合作的) decision made at intergovernmental (政府间的) levels.”1.The water crisis will become more serious because of.A.serious pollutionB.a growing populationC.high expensesD.lack of sea water2.The most important way of dealing
