[课时作业] [限时30分钟] Ⅰ.阅读理解 A The streets of Seville, Spain, are lined with over 48，000 attractive orange trees, producing over 16，500 tons of fruit every winter.Though that gives Seville the honor of being Europe's top orange­producing city, the fruit is too sour to be consumed fresh.Some of the produce is used to make jam, but most ends up in landfills.However, that may change soon thanks to an inventive idea to use the oranges to produce clean energy. The pilot program is being launched by the local government and parks department in cooperation with Emasesa, Seville's water supply division.Juice obtained from 38.6 tons of oranges will be left to ferment (发酵) in an existing biogas facility.The gas released from the fermented liquid will be collected and used to drive a generator to produce clean power.The officials estimate the test run will generate about 1，500 kW·h of energy—enough to run one of Emasesa's water purification plants.They say, “It's not just about saving money.The oranges are a problem for the city, and we're producing added value from waste.” If successful, by 2023, the city hopes to recycle all the oranges and add the electricity generated back to its power system.In trial runs, 1000 kilos of oranges produced 50 kW·h of clean energy—enough to satisfy the daily electricity needs of five homes. “Emasesa is now a role model in Spain for sustainability and the fight against climate change，” Espadas Cejas, mayor of Seville, said in the press conference announcing the pilot program.“This project will help us reach our targets for reducing emissions (排放)，energy self­sufficiency, and the circular economy.” The latest attempt is among the many initiatives being carried out across Spain to achieve the country's goal of switching its electricity system to renewable sources by 2050—and if everything goes according to plan，folly decarbonizing its economy shortly after that.
