17、n A(总题数：1，分数：35.50)So-called “green roofs“ urban rooftops covered with grasses, plants and other types of greeneryare becoming increasingly popular around the world. In France, newly built commercial rooftops must have either greenery or solar panels, according to a recent law. The logic is obvious:

18、 Green roofs can reduce the retention (滞留) of 1 in urban areas, help to cool down buildings and thereby lower their energy use, and even pull some carbon dioxide from the air and 2 it back into plant growth. Plus, they look cool. But the psychological benefits of green roofs to busy office workers m

In a study published in the journal Environmental Psychology , the University of Melbourne“s Kate Lee and a group of colleagues found that interrupting a tedious, attention-demanding task with a 40-second “microbreak“in which one 4 looks at a computerized im

Other psychological benefits of nature views have also been 9 in recent literature. In one study, resear

23、bstantial O. sustainable（分数：35.50）八、Section B(总题数：1，分数：71.00)We“ve Been Imagining Mountains All Wrong, Say ScientistsA. From the simplest sketches to the most advanced scientific models, illustrations of mountains pretty much all look the same. Their classic pyramid form, wider at the bottom and nar

24、rowing all the way up to the top, has been ingrained in the human mind, and scientists have always assumed that the land area in mountain ranges decreases the higher you climb. Until now, that is. B. New research published Monday in Nature Climate Change reveals a surprising discovery that not only

25、changes the way we think about mountains but could also have big implications for how we understand, monitor and protect the organisms that call them home. It turns out mountain ranges don“t just come in the familiar pyramid formin fact, most of them have a different shape entirely. C. Researchers M

26、organ Tingley and Paul Elsen used satellite data on mountain ranges from around the globe to analyze how the amount of the land area changed with increasing elevation (海拔). They learned that pyramidal mountain ranges account for just 32 percent of the mountain ranges on Earth. Of the remaining mount

27、ain ranges, six percent have an inverse, or upside-down, pyramid form, with the land area increasing toward the top; 23 percent have an hourglass (沙漏) shape, being wider and at the bottom and top and pinched (挤压) in the middle; and 39 percent have a diamond form, with less land areas at the top and

28、bottom and more available in the middle. D. “I did expect that we“d see some patterns that were not this classic pyramid,“ says Elsen, lead author and PhD student in Princeton University“s ecology and evolutionary biology department. In fact, Elsen got interested in conducting the study while doing

29、field research in the Himalayas. He noticed that as he hiked to the tops of the mountains, the land area seemed to increase, rather than decrease, at high elevations. Still, he says, “I had no idea that pyramid mountains would be the exception to the rule.“ E. It“s hard to tell the true form of a mo

30、untain range just by looking at any given mountain peak, since most individual mountains still come to a point at the very top. But mountain ranges are so big, and their topography (地形) so complex, that it would be impossible to observe their true shapes just by looking at them. That“s why the resea

31、rchers had to analyze satellite data, looking at the total surface area in relation to elevation across the whole mountain range, to complete their study. The way the land area is distributed on a landscape scalewhether the greatest area lies at the top, bottom or in the middle when you take into ac

32、count all the slopes, ravines and plateaus that make up the mountainsis what determines a mountain range“s designation as a pyramid, inverse pyramid, diamond or hourglass. F. The finding doesn“t just flip our view of mountain topography. More importantly, it changes our understanding of how climate

33、change can affect mountain-dwelling species, the authors say. Organisms that live on mountains are in a particular pickle when it comes to climate change. These species tend to be highly specialized and do best in particular habitats and narrow temperature ranges. As global temperatures rise, the be

34、st way to find cooler spots is to move higher up on the mountain. But in pyramidal mountain ranges, which get narrower toward the top, moving higher also means losing the land area. Having less available space can cause populations to shrink and can put them at an increased risk of dying out entirel

35、y. G. But Elsen and Tingley“s research shows that the pyramid model doesn“t hold true for all, or even most mountain ranges, meaning space shortages might not always fall where scientists think they do. In hourglass mountains, for example, the most constricted (狭窄的) space will be in the middle of th

36、e mountain, rather than at the top. On the other hand, species on diamond mountains will see the widest spaces in the middle. And species on inverse pyramids will enjoy increasing land areas all the way up to the top of the mountain. H. “I think this is critical information that will really inform o

37、ur understanding of mountain species,“ says Robert Guralnick, a biodiversity scientist and curator (馆长) at the University of Florida“s natural history museum, who was not involved with the study. “The models we“ve been using are typically that mountain ranges are narrowing toward the top.“ More real

38、istic models and a better understanding of mountain topography can help conservationists make better decisions when monitoring and managing mountain species, the paper“s authors say. “This is absolutely an important study for informing our conservation policy,“ Elsen says. Knowing where the land are

39、a is likely to be scarce can help conservationists target the right places and the right species. I. In some cases, new knowledge could even indicate that climate change doesn“t threaten a species in quite the way scientists thought. The Himalayan monal, for example, is a colorful bird that lives in

40、 the Himalayan mountains, which have the hourglass form. Currently, the bird prefers an elevation that“s right in the middle of the hourglass, says Morgan Tingley, senior author and assistant professor of ecology and evolutionary biology at the University of Connecticut. So space may be pinched for

41、it now, but if warming temperatures force the bird into higher elevations, it will likely enjoy more space as it moves upward. J. On the other hand, a bright little bird called the beautiful nuthatchwhich is already classified as a vulnerable species by the International Union for Conservation of Na

42、turelives just below the pinched part of the hourglass. If it were to flee to higher ground, it would lose the land area. “This current research is showing that there are potentially optimistic futures for some species, and it“s also highlighting these bottleneck zones,“ Elsen says. K. The research

43、is also relevant for species that move downslope in response to climate change, chasing the increased precipitation that comes with warmer temperatures. Before now, most scientists might have assumed that any species moving downhill would be able to take advantage of greater and greater land areas a

44、s it moved along. Now we know that in certain mountain ranges, these species may actually encounter a shortage in space as they move toward the base of the mountain, and their populations may shrink as a result.（分数：71.00）(1).As for inverse pyramidal mountains, species have wider land areas all the w

47、nd area and finally the risk of extinction.（分数：7.10）(7).Except for the pyramid form, mountain ranges have got other forms like the inverse pyramid form, an hourglass shape and a diamond form.（分数：7.10）(8).The finding changes our understanding of how climate change can affect species living in the mou
