While fossil fuels-coal,oil,gas-still generate roughly 85 percent of 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 by governments 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.

28.【题干】It can be learned that in Iowa,______.

【选项】

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

29.【题干】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.30.It can be inferred from the last paragraph that renewable energy _____.

【选项】

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

28—29参考答案及解析：

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

【解析】这是一道是非细节题，根据题干给出的段落位置，5-6两段和主题词clean energy，回到原文的第5-6段，这两段都不长，第五段出现了But后讲到电池容量的提升a boost in the storage，与A选项不符，并不是因果关系，故排除；B选项说道广泛用在制造业也不符合原文第六段第一句；而D选项和原文第六段最后一句是语义相反的，故也排除；正确选项C是和这句话语义一致的，也是和全文主题一致的，故为正确答案。
