2018年考研英语二真题及答案：阅读理解TEXT2

While fossil fuels- coal,oil,gas- still generate roughly 85 percentof the
world's energy supply,it'sclearer than ever that the future belongs to renewablesources such as wind and solar.The move to renewables is picking up momentumaround the world: They now account for more than half ofnew power sourcesgoing on line.
Some growth stems from a commitment bygovernments and farsighted
Businssesto fundcleanerenergy sources.But increasinglythestoryisabout theplummeting prices of renewables,especially wind and solar.The cost of solarpanels has dropped by 80 percent and the cost of wind turbines by close taone-third in the past eight years.
In many parts of the world renewable energy is already a principal energy source.In Scotland,for example, wind turbines provide enough electricity to power 95 percent of homes. 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.
President Trump has underlined fossil fuels - especially coal - as the path to economic growth. 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.
The question “what happens when the wind doesn't blow or the sun doesn'tshine?" has provided a quick put-down for skeptics. But a boost in the storage apacity of batteries is making their ability to keep power flowing around the clock more likely.
The advance is driven in par by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now. this massive investment could change the picture rapidly in coming years.
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 a time of a global shift in thought.

31. 答案 [B]user information
解析：细节题。根据题干信息定位到第一段第二句。该句提到两年前Facebook花了更多的钱获得了WhatsApp的信息服务。接着提到WhatsApp提供给Facebook的是关于其用户的朋友圈以及社会生活等具体精炼的信息。由此可知，B项为正确答案。
32. 答案[C]pose a risk to Facebook users
解析：细节题。根据题干关键词linking the phone number定位第二段第一句。该句提到Facebook向欧洲委员会承诺不会把用户的电话号与Facebook的身份认证连系到一起，但是协议通过之后Facebook立马失信。接下来提到“甚至都不清楚信息里面都有什么，也不知谁发的消息，发送的目的又是什么”。因此，可能会给用户造成风险。因此C项符合文意。
33. 答案 [D]cannot keep pace with the changing market
解析：细节题。根据题干关键词competition law 定位到第三段第一句。该句指出“竞争法似乎成为解决这些不平等权力的唯一办法，但是此法案太过笨拙”。下一句提到“一方面，相比于数据经济变化的速度，此法案发展是非常缓慢的”。由此可知，该法案跟不上当前市场变化的步伐。因此D项为正确答案。
34. 答案[D]the services are paid for by advertisers.
解析：根据题目中的because 可确定为因果细节题。题干中的信息出现在第三段后半部分，是题目中的原词 competition law as presently interpreted，而原因在其后面的句子。下文写到，the users of their services are not，读到这里的not，一定要找而是谁。继续读下一句，That would be the people who buy advertising from them…，与选项对应，可得出[D]the services are paid for by advertisers。
35. 答案[D]the relationship between digital giants and their users.
解析：根据题目中is used to illustrate可判断为例证题，要找到the ants analogy论据所证明的论点;论点在论据之前，因此先找到论据the ants analogy，再找到论据前的论点句。所以本题定位到最后一段的第一句，The product …is data，and we…convert our lives to data…。此句中，data即digital giants，we 即 users。因此答案为[D]the relationship between digital giants and their users.
