2018年考研英语二试题与答案解析（完整版）_第4页

　　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.

　　26.【答案】 C falling

　　【解析】这是一道词义句意题，要想知道plummeting 的意思，首先要回到原文找线索，即plummeting所在的句子以及上下句，由原文可知，plummeting所在句子是在说现在例如风能和太阳能这样的可再生资源的价格的问题，plummeting是修饰可再生资源的价格的，接着二段最后一句就在用具体数字来证明可再生资源的成本在下降，如太阳能成本下降了百分之八十，风能也降到三分之一，由此可知，可再生资源的成本在下降，plummeting的含义是下降的意思。所以选择C falling。

　　27. 【答案】A is progressing notably

　　【解析】这是一道具体细节题，根据题干关键词定位至第三段第三句及第四句，意思是“在中国和欧洲等国家已经领先时，美国也在见证着巨大的改变。根据美国能源信息局报道，三月份，美国首次使用风能和太阳能产生了超过百分之十以上的能源。”这足以说明在美国，可再生能源的使用正在取得显著地进步。所以答案是A。

　　28. 【答案】 A wind is a widely used energy source

　　【解析】这是一道细节推断题，根据题干关键词定位至第四段第三句，在爱荷华州，风力涡轮机点缀着这个州并提供了此州百分之三十六的电能，并且还吸引了像微软这样的科技巨头公司。因此可判断，在爱荷华州，风能是一种广泛使用的能源。所以答案是A。

　　29.【答案】 C its continuous supply is becoming a reality
