City of The Future Reading Explorer 3-7B @PDD 小牛教辅 Before You Read ecological footprint take action metropolis Before You Read A modern city like Dubai could find alternative ways to produce energy, such as solar power. There is a lot of sunlight in the Middle East so that might be a good choice. City of The Future City of The Future To appreciate the audacity' of Dubai, you could start by going sking. The ski Tesort, located inside one of the city's shopping malls, looks from the outside like a silver spaceship. You put on a thick coat, pull on your gloves and then marvel at what strong air-conditioning can do. At the exit, you can buy a souvenir T- shirt. A cartoon thermometer in Celsius announces: "I went from +50 to minus 8!" audacity n.鲁莽;大胆无礼 Audadty its a willingness to be bold and daring. Dubai 迪拜 City of The Future Indoor sking in the desert has become a symbol of Dubai's status as a wealthy, modern metropolis. Originally a small fishing village, Dubai's fortunes changed forever with the discovery of oil in the 1960s. Since then, it has evolved to become the largest city in the United Arab Emirates, with over three million residents, huge shopping malls, and a hundred high-ise towers. But the rapid growth has come at a price. To power its cars and air conditining the city has produced large amounts of carbon dioxide (CO2) from fossil fuels. By 2006, Dubai had one of the largest ecological footprints in the world. But now it is making some big changes. wealthy adj.富有的 ; 富裕的 United Arab Emirates 阿拉伯联合酋长国 carbon dioxide n. 二氧化碳 footprints n.脚印 City of The Future To reduce its dependence on cars and lower its emissions, Dubai has invested in solar energy, green buildings, and a comprehensive public transportation system. Glearming driverless trains now run beside the main roads. In addition, all new buildings must meet strict energy regulations. Smart lighting and cooling systems must switch off when no people are present in a room. New buildings must also use solar panels for water heating. "The leadership has recognized that the growth of the economy is not sustainable without taking action on emissions," says Tanzeed Alamy a climate and energy specialist. emission n.排放 ; 排放物 ; 发出 ; 射出 ; 散发物 comprehensive adj. 综合的 ; 所有的 ; 综合性的 ; regulation n.法规 ; 管理，控制 ; 规则 ; cooling v. 变凉，冷却 ; 冷静下来 ; sustainable adj. 可持续的 ; 不破坏生态平衡的，合理利用的 City of The Future The most striking development can be found where the city's suburbs meet the desert. Unlike much of Dubai, the Sustainable City to the south feels more like a close- knit? vllage community. About five hundred low- rise houses are distributed along attractive, tree -lined streets. They all face north, away from direct sunlight, and are close together to provide natural shade. Each building has reflective windows and wall paint, which reduce the heat absorbed from the sun. Rooftop solar panels and energy- saving lights contribute to the community's energy efficiency. As a result, residents of the Sustainable City now consume 50 percent less energy than people living in other parts of Dubai. close- knit 紧密编织 A group of people that is dose-knit is ighty connected distributed adj.分布的;分散的 reflective adj.反思的 ; 反射热的 It’s a surface is reflective, it casts back light or heat. efficiency n.效率; 功率 resident n.居民; 住户 City of The Future A decade ago, the idea of a fully sustainable community was thought to be unrealistic. But times have changed, says Faris Saeed, one of the creators of the Sustainable City. So, too, have prices. The cost of living in the Sustainable City is similar to some of Dubai's other neighborhoods. "It's a myth that sustainable has to be more expensive," Saeed says. Dubai's leaders hope the Sustainable City will become a model for the future. By 2050, the government intends to obtain 75 percent of the city's energy from renewable sources-mainly solar. It also wants to have the smallest ecological footprint in the world. The plan is audacious. But if successful, even guilt- free sking in the desert could become an environmentally sustainable reality. unrealistic adj.不切实际 ; 不实事求是的 myth n.神话 ; 神话故事 A myth is a widely held but false belief or idea. audacious adj.大胆的 ; 敢于冒险的 WHAT MAKES A GREEN BUIL DING ? Though standards for green buildings vary, they are generally designed to use less energy and water and improve the indoor environment, including air quality. Post -Reading Reading Comprehension Reading Comprehension Reading Comprehension Reading Comprehension C F G B D A Reading Skill Reading Skill Positive words: carbon-rich, vital, abundant, inexpensive Negative words: dirty, dangerous, grave risks, deadly diseases, recklessly, toxic, polluting, foolhardy, irresponsible Possible answer(s): I think the author's tone is negative because there are many more negative words. The author thinks coal is dangerous to human health and that it should be replaced now. Reading Skill I think the author's tone is positive because they have given examples of good things Dubai is doing to reduce its emissions. Reading Skill Dubai has invested in solar energy, green buildings, and public transportation. All new buildings must meet strict energy regulations and use solar panels. My country gives a discount to people who have solar panels on their roofs, and provides tax incentives to people who buy energy-efficient appliances and cars that use less gasoline.

In some places, it could interfere with navigation or fishing. I think it depends on the location of the place, its weather, and the attitudes of local people toward new sources of energy. null, track 1 2019 245201.42 $$
