第2题
Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. 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.
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’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.
The advance is driven in part 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 at a time of a global shift in thought.
26、The word "plummeting" (Line 3, Para 2) is closest in meaning to_____.
A.stabilizing
B.changing
C.falling
D.rising
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
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
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
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 with regard to its cost

听力原文：M: Hey, Michelle. Look what I just found. Right here in the sand.
W: A piece of wood？ Oh. Driftwood. Interesting shape... Almost like some sort of modern sculpture.
M: Yeah. And feel how smooth it is.
W: Hmm, Must've been in the water a long time. It could've been drifting in the ocean currents for months, or even years.
M: In the currents？ Doesn't the wind just blow things around out there？
W: Well, sure. But the currents are always moving, too. Almost like rivers, but underwater rivers, flowing through the ocean.
M: So how do they find out where these currents go？ Stick a message in a bottle and throw it in the water？
W: Don't laugh. In fact, I was reading in a science magazine that oceanographers have released huge numbers of bottles into the ocean over the years. They wanted to map out where the currents would carry them.
M: Say, I'll bet-after they found out where all those bottles ended up-they could enter all that data in to a computer and make a pretty detailed model to... to show where the currents go.
W: In fact, they did. And they also found a neat way to test that model. There was a freighter carrying sneakers from a factory in Asia. It was caught in a big storm and thousands of pairs of sneakers got dumped in the Pacific Ocean.
M: Really？ What a waste!
W: Yeah. Turns out, though, that hundreds of these shoes started washing up on beaches somewhere near Seattle, just about where the computer models had predicted the currents would carry them.
M: Gee. You mean all that stuff I find on the beaches might be part of some big scientific experiment？ I thought it was all just trash!
