26. The word “plummeting” (Line 3, Para. 2) is closest in meaning to.
- A. stabilizing
- B. changing
- C. falling
- D. rising
答案：C
答案句：But increasingly the story is about the plummeting prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.
参考译文：但越来越多的故事是关于可再生能源（尤其是风能和太阳能）价格的急剧下降。在过去八年中，太阳能电池板的成本下降了80%，风力涡轮机的成本下降了近三分之一。
定位线索：题干“plummeting”（第2段第3行）→答案句取自第2段“plummeting prices of renewables”；文中“dropped by 80 percent”和“dropped by close to one-third”对应选项C“falling”（下降）。
解析：题干要求猜测“plummeting”的词义。答案句明确指出可再生能源价格“plummeting”，随后用具体数据说明：太阳能电池板成本“dropped by 80 percent”，风力涡轮机成本“dropped by close to one-third”，这些数据直接表明价格在下降，因此“plummeting”意为“falling”（下降）。选项A“stabilizing”（稳定）、B“changing”（变化）和D“rising”（上升）均与原文数据不符，属于无中生有或偷换概念。
27. According to Paragraph 3, the use of renewable energy in America.
- A. is progressing notably
- B. is as extensive as in Europe
- C. faces many challenges
- D. has proved to be impractical
答案：A
答案句：While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.
参考译文：虽然世界其他地区（尤其是中国和欧洲）处于领先地位，但美国也在经历显著的转变。据美国能源信息署报道，今年3月，风能和太阳能发电量首次占美国发电总量的10%以上。
定位线索：题干“According to Paragraph 3”→答案句取自第3段“the United States is also seeing a remarkable shift”；文中“remarkable shift”和“for the first time, wind and solar power accounted for more than 10 percent”对应选项A“is progressing notably”（正在显著进展）。
解析：题干问美国可再生能源的使用情况。答案句指出美国“seeing a remarkable shift”，并给出具体数据：风能和太阳能首次占美国发电量的10%以上，这直接说明美国可再生能源使用正在显著进展，对应选项A。选项B“as extensive as in Europe”（与欧洲一样广泛）在原文中无依据，原文只说欧洲领先，未比较程度；选项C“faces many challenges”（面临许多挑战）和D“has proved to be impractical”（已被证明不切实际）均与原文积极态度相反，属于无中生有。
28. It can be learned that in Iowa,.
- A. wind is a widely used energy source
- B. wind energy has replaced fossil fuels
- C. tech giants are investing in clean energy
- D. there is a shortage of clean energy supply
答案：A
答案句：In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation – and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.
参考译文：在最近一次艾奥瓦州的演讲中，他（特朗普总统）将风能斥为不可靠的能源。但这一信息在艾奥瓦州许多人中并不受欢迎，那里风力涡轮机遍布田野，提供了该州36%的发电量——而且像微软这样的科技巨头正被清洁能源的可用性所吸引，为其数据中心供电。
定位线索：题干“in Iowa”→答案句取自第4段“in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation”；文中“wind turbines dot the fields”和“provide 36 percent”对应选项A“wind is a widely used energy source”（风能是一种广泛使用的能源）。
解析：题干问从文中可以了解到艾奥瓦州的什么情况。答案句描述艾奥瓦州“wind turbines dot the fields”（风力涡轮机遍布田野）且“provide 36 percent of the state’s electricity generation”（提供该州36%的发电量），这些信息直接表明风能在艾奥瓦州被广泛使用，对应选项A。选项B“wind energy has replaced fossil fuels”（风能已取代化石燃料）程度过重，原文只说提供36%发电量；选项C“tech giants are investing in clean energy”（科技巨头正在投资清洁能源）偷换概念，原文说科技巨头“被吸引”来使用清洁能源，并非投资；选项D“there is a shortage of clean energy supply”（清洁能源供应短缺）与原文“availability of clean energy”（清洁能源的可用性）相反，属于无中生有。
29. Which of the following is true about clean energy according to Paragraphs 5&6？
- A. Its application has boosted battery storage.
- B. It is commonly used in car manufacturing.
- C. Its continuous supply is becoming a reality.
- D. Its sustainable exploitation will remain difficult.
答案：C
答案句：The question “what happens when the wind doesn't blow or the sun doesn't shine?” has provided a quick put-down for skeptics. But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.
参考译文：“当风不吹或太阳不照耀时会发生什么？”这个问题为怀疑论者提供了快速的贬低。但电池存储容量的提升正使它们全天候保持电力流动的能力更有可能实现。
定位线索：题干“Paragraphs 5&6”→答案句取自第5段“a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely”；文中“keep power flowing around the clock”对应选项C“Its continuous supply is becoming a reality”（其持续供应正成为现实）。
解析：题干问关于清洁能源，根据第5、6段哪项正确。答案句指出电池存储容量的提升使“keep power flowing around the clock”（全天候保持电力流动）“more likely”（更有可能），这直接对应选项C“Its continuous supply is becoming a reality”（持续供应正成为现实）。选项A“Its application has boosted battery storage”（其应用提升了电池存储）因果颠倒，原文是电池存储提升使清洁能源持续供应成为可能；选项B“It is commonly used in car manufacturing”（它在汽车制造中普遍使用）与原文“electric cars are still a rarity on roads now”（电动汽车在路上仍然罕见）矛盾；选项D“Its sustainable exploitation will remain difficult”（其可持续开发仍将困难）与原文积极趋势相反，属于偷换概念。
30. It can be inferred from the last paragraph that renewable energy.
- A. will bring the US closer to other countries
- B. will accelerate global environmental change
- C. is not really encouraged by the US government
- D. is not competitive enough with regard to its cost
答案：C
答案句：While there’s a long way to go, the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up – perhaps just in time to have a meaningful effect in slowing climate change. What Washington does – or doesn't do – to promote alternative energy may mean less and less at a time of a global shift in thought.
参考译文：虽然还有很长的路要走，但可再生能源的趋势线正在飙升。能源变化的步伐似乎正在加快——也许正好能对减缓气候变化产生有意义的影响。在全球思想转变之际，华盛顿在推广替代能源方面做什么——或不做什么——可能意义越来越小。
定位线索：题干“last paragraph”→答案句取自末段“What Washington does – or doesn't do – to promote alternative energy may mean less and less”；文中“What Washington does – or doesn't do”对应选项C“is not really encouraged by the US government”（并未真正受到美国政府鼓励）。
解析：题干要求从最后一段推断可再生能源的情况。答案句指出“What Washington does – or doesn't do – to promote alternative energy may mean less and less”（华盛顿在推广替代能源方面做什么或不做什么可能意义越来越小），这暗示美国政府并未真正积极鼓励可再生能源，且其影响在减弱，对应选项C。选项A“will bring the US closer to other countries”（将使美国与其他国家更接近）无中生有，原文未提及；选项B“will accelerate global environmental change”（将加速全球环境变化）与原文“slowing climate change”（减缓气候变化）相反；选项D“is not competitive enough with regard to its cost”（在成本方面不够有竞争力）与第2段价格下降的事实矛盾，属于偷换概念。
