It does, however, have its own problem. Race walkers are conditioned athletes. The longest track and fiel

2、d event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sports rules require that a race walkers knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. Its this strange form

3、 that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass. Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six

4、miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour. However, race walking does not pound the body as much as running does, Dr. Norber

5、g says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step. As a result, she says, some of the injuries associated with running, such as

6、 runners knee, are uncommon among race walkers. But the sports strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a co

In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatm

18、ent that would last the plants lifetime. The engineers are also trying to develop an on and off switchwhere the glow would fade when exposed to daylight. Lighting accounts for about 7% of the total electricity consumed in the US. Since lighting is often far removed from the power source(电源)-such as

40、r ends up in the fashion shows like the one in Brooklyn last month. Nutria were brought there from Argentina by fur farmers and let go into the wild. The ecosystem down there cant handle this non-native species(物种).Its destroying the environment. Its them or us. says Michael Massimi, an expert in th

41、is field. The fur trade kept nutria check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy. Biologist Edmond Mouton runs the nutria control program for Louisiana. He says its not easy to convince people that nutria fur is green, but h

42、e has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Moutons job these days is trying to promote fur. Then theres Righteous Fur and its unusual fashion. Model Paige Morgan says，To give people a guilt-free option that they can wear without someone throwing paint

43、 on them-1 think thats going to be a massive thing, at least here in New York. Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable.

B 【解析】【解析】 【分析】 本文是说明文。介绍了美国新奥良和布鲁克林举办了不同寻常的时装秀。展出海狸鼠制成的皮衣。海狸鼠 们每年都在破坏大片的湿地，因此设计师称这是一种环保的举措，科学家们也对海狸鼠损坏生态平衡表示 了担忧。 28. 推理判断题。根据第二段 Unusual fashion shows in New Orleans and Brooklyn

47、 have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year,”says Cree McCree, project director of Righteous Fur.得知，美国新奥尔良和 布鲁克林举办了不同寻常的时装秀，时装秀上展出海狸鼠皮制成的不同风格的衣服，项目总监 Cree

48、 McCree 说： “除非了解海狸鼠正每年破坏大片湿地，否则谈论无罪感皮衣是很疯狂的事情” ，可以判断出由于海狸 鼠对生态造成了巨大的破坏，这场海狸鼠皮衣时装秀销售的是无罪恶感皮衣。故选 A。 29. 推理判断题。根据第三段 Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail.得知， 科学家们如此担心以至于他们决定按照一条海狸鼠尾巴付给猎人们 5美元，可以推断出科学家们担忧海狸 鼠们严重破坏生态平衡， 。故选 A。 30. 词义猜测题。根据第五段 The fur trade

49、kept nutria in check for decades, but when the market for nutria collapsed in the late 1980s,the cat-sized animals multiplied like crazy. 得知，毛皮贸易使海狸鼠受到了几十年的控制，但是 当海狸鼠市场在 20 世纪 80 年代末崩溃时，这种猫大小的动物数量疯长，根据 but判断，这是转折关系，以 前由于皮毛交易，海狸鼠处于控制，现在这种海狸鼠之所以能够数量激增，是由于市场不再销售海狸鼠皮 毛导致的，可以推断出划线词 collapsed 是和 D.crashed倒闭的意思最相近。故选 D。 31. 推理判断题。根据第二段 Model Paige Morgan says, “To give people a guilt free
