1、Walking to Exercise the BrainDo you think sitting and studying all the time will improve students grades? Think again. Getting some exercise may help, too.New research with older people suggests that taking regular walks helps them pay attention better than if they didn\'t exercise.Previous research had shown that mice learn, remember and pay attention better after a few weeks of working out on a running wheel. Mice that exercise have greater blood flow to the brain than those who don\'t. Their brain cells also make more connections.Neuroscientists (神经科学家) from the University of Illinois at Urbana Champaign wanted to find out if the same thing is true forpeople. First, they measured the physical fitness of 41 adults, ages 58 to 77, after each person walked I mile. Then, participants looked at arrows on a computer screen and had to use computer keys to show which way one particular arrow was pointing.Adults who were physically fit were faster at the arrow task, and their answers were just as accurate as their less - fit peers, the researchers found. The fitter participants also had more blood flow to a part of their brain responsible forpaying attention and making decisions.In a second study, 15 elderly people who completed a 6 - month aerobic - training (有氧运动) course were faster at attention tasks compared with 14 seniors who just did stretching and toning (韵律操) exercises forthe same amount of time.So, even going fora walk every 2 or3 days forjust 10 to 45 minutes can help. That should be good news forthe elderly.The effects of exercising on the brains of younger people haven\'t been studied yet. Still, it can\'t hurt to take occasional breaks and go fora walk orrun around with friends. Whatever you do, though, don\'t try to read and walk at the same time. You could end up hurting yourself!It is suggested in the last paragraph that people should ______.【单选题】

A.run around once a week

B.not read and walk at the same time

C.go fora walk every day

D.not hurt their friends while exercising

正确答案:B

答案解析:本题难度不大,找到答案依据不难。答案依据在最后一段点评:本题难度不大,找到答案依据不难。第三句。这句话谈到。不论你做什么,都不要一边走路一边看书,回来看选项,很明显,B是同义解释,是答案。

2、Waving With LightIn the Sierra Madre mountain range of west central Mexico, the native Huichol people live much the way their ancestors did without electricity. That\'s because it\'s too expensive to string power lines to the remote mountain areas where they live. To help support themselves, the Huichol create beautiful artwork. They sell their art in cities hundreds of miles away from their villages. and without electricity at home oron the road, they can only work during daylight hours. When it gets dark, they must stop whatever they\'re doing. Now, a team of scientists, designers, and architects are using new technologies to provide the Huichol with light after the sun sets. The scientists\' technique involves weaving tiny electronic crystals into fabrics that can be made into clothes, bags, orother items. By collecting the sun\'s energy during the day, these lightweight fabrics provide bright white light at night. Their inventors have named the fabrics "Portable Lights." Portable Lights have the potential to transform the lives of people without electricity around the world, says project leader Sheila Kennedy. "Our invention," Kennedy says, "came from seeing how we could transform technology we saw every day in the United States and move it into new markets forpeople who didn\'t have a lot of money."At the core of Portable Light technology are devices called high-brightness light-emitting diodes, orHB LEDs. These tiny lights appear in digital clocks, televisions, and streetlights. LEDs are completely different from the light bulbs. Most of those glass bulbs belong to a type called incandescent lights. Inside, electricity heats a metal coil to about 2,200 degrees Celsius. At that temperature, bulbs give of flight we can see. Ninety percent of energy produced by incandescent lights, however, is heat and invisible. With all that wasted energy, bulbs burn out quickly. They are also easily broken. LEDs, on the other hand, are like tiny pieces of rock made up of molecules that are arranged in a crystal structure. When an electric current passes through an LED, the crystal structure produces light. Unlike incandescent bulbs, they can produce light of various colors. Within an LED, the type of molecules and their particular arrangement determines what coloris produced. What is the most important part of the Portable Light technology?【单选题】

A.HB LEDs.

B.Glass Bulbs.

C.Incandescent lights.

D.Heated metal coils.

正确答案:A

答案解析:第6段第1句提供了答案。Portable Lights技术的最主要部分是high-brightness light-emitting diodes,即高亮度发光二极管。

3、Shopping at Second - hand Clothing StoresWhen 33 year old Pete Barth was in college, shopping at second hand clothing stores was just something he did- "like changing the tires on his car." He looked at his budget and decided he could save a lot of money by shopping forclothes at thrift shops."Even new clothes are fairly disposable (用后即丢掉的) and wear out after a couple of years," Barth said. "In thrift shops, you can find some great stuff whose quality is better than new clothes."Since then, Barth, who works at a Goodwill thrift shop in the US state of Florida, has found that there are all kinds of reasons forshopping forsecond - hand clothing. Some people, like him, shop to save money. Some shop fora crazy - looking shirt. and some shop as a mean conserving energy and helping the environment.Pat Akins, an accountant at a Florida Salvation Army (SA) (救世军) thrift shop, said that, forher, shopping at thrift shops is a way to help the environment."When my daughter was little, we looked at it as recycling," Akins said. "Also, why pay 30 dollars fora new coat when you can get another one fora lot less?"Akins said that the SA has shops all over the US- "some as big as department stores. All of the clothes are donated (捐赠), and when they have a surplus (盈余), they\'ll have" stuff a bag" specials, where customers can fill a grocery sack with clothes foronly 5 or10 dollars.Julia Slocum, 22, points out, however, that the huge amount of second - hand clothing in the US is the result of American wastefulness."I\'d say that second - hand stores are the result of our wasteful, materialistic culture," said Slocum, who works fora pro - conservation organization, the center of a New American Dream. "Thrift shops prevent that waste from going to landfills (垃圾填埋场). They give clothing a second life, provide cheaper clothing forthose who can\'t afford to buy new ones and generate (创造) income forcharities. They also provide a way forthe wealthy and middle classes to shed (摆脱) the guilt fortheir level of consumption.Thrift shops can do everything EXCEPT ______. 【单选题】

A.give clothing a second life

B.generate income forcharities

C.provide cheaper clothes forthe poor

D.stop rich people from wasting money

正确答案:D

答案解析:本题有一定难度,需要认真阅读文章,答案依据在文章最后一段。最后一段谈到,旧货店给了服装二次生命,给那些买不起新衣服的人提供便宜衣服,还把一些收入捐给慈善机构,但没有提到阻止富人浪费钱,所以答案是D。

4、AirbusDespite bulging orcerbooks, the mood at Airbus and Boeing is far from celebratory. Both aviation giants are moaning loudly that their production systems and supply chains are flawed, albeit forostensibly different reasons. This week Louis Gallois, the boss of EADS, the Franco-German aerospace consortium that owns Airbus, added substance to warnings a week earlier by the planemaker’s chief executive, Tom Enders, that the dollar\'s decline was "life-threatening" forthe firm. Mr. Gallois said it was no longer just a possibility that Airbus would have to move a large part of its production to "the dollar zone" orlow-cost countries, but a certainty.Airbus is already in the middle of Power 8, a big restructuring plan that involves the loss of 10,000 jobs and the sale of several plants, which is meant to offsetthe losses caused by the delays in delivering the A380 superjumbo. But Power 8 assumed that a euro was worth $ 1.35, not today\'s $ 1.47. Mr. Gallois estimates that each 10-cent rise in the euro costs Airbus 1 billion. At present, Airbus makes 76% of its purchases within Europe, but generates over 60% of its sales elsewhere. It must now shift some production abroad.Airbus is now likely to forge ahead much further. Mr. Gallois suggests that when the A350 enters service in 2013, 70% of it will have been "purchased" in dollars, against 50% forthe A380 and an average 24% of Airbus production today. Because Airbus insists that some of its European suppliers price in dollars that means about 50% of the A350\'s production will be outsourced. New aircraft, such as the A320\'s successor, may be made almost entirely outside the euro-zone.Airbus maintains that exchange rates are not the only reason foroutsourcing: it is keen to tap into composite-manufacturing expertise wherever it exists. It also insists that it will not repeat the mistakes Boeing has made with its new 787 Dreamliner, about 80% of which has been outsourced. A few weeks ago Mike Bair, the executive responsible forthe 787 programme, who was recently moved sideways after mounting production delays, launched a withering attack on some of the companies recruited to build the plane. He said that in future Boeing would not entrust design work to partners who "proved incapable of doing it", and would make suppliers build factories close to Boeing\'s main assembly operation, rather than flying semi-finished sections of the aircraft round the world on huge Dreamlifter transporters.It is too early to conclude that the two rivals are heading in opposite directions- Boeing renouncing the global supply chain just as Airbus adopts it. Each company has its own axe to grind. Airbus needs greater flexibility, and the weak dollar provides helpful cover as it takes on its grumbling unions. Boeing, forits part, wants to shift the blame fordelays to the 787 on to its partners. The logic of global outsourcing in the aerospace industry remains powerful. Whatever they may be saying now. Airbus and Boeing are more likely to converge than to diverge.The lesson Airbus learns from Boeing\'s case of 787 Dreamliner is ______.【单选题】

A.it should not adopt outsourcing at all given its uncertainty and insecurity

B.it should not cooperate with partners in designing

C.it should not waste time in flying the semi-finished sections of the aircraft

D.it should make use of the local manufacturing expertise instead of international partners

正确答案:D

答案解析:细节考查题。题干考查的是从波音787“梦之机”事件中空中客车得到的教训是什么。答案参见第四段:空中客车指出要海外采购的另外一方面原因是如果当地有制造技术那么就直接运用该技术,故正确答案为D。
