1、African wild dogFinding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.There is a tension between babysitting and hurting.【单选题】

4、DyslexiaAs many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world\'s great thinkers and scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventor Thomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby\'s body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent or creative.The left side of the brain in a dyslexic person is bigger than the right side.【单选题】

6、Britain\'s Solo SailorEllen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money for three years to buy her first small sailing boat. When she was 18, she sailed alone around Britain and won the "Young Sailor of the Year" award.Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors and she was given a very warm welcome when she returned.Ambition and determination have always been a big part of Ellen\'s personality. When she was younger, she lived in a kind of hut (棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race. Then she took a one - way ticket to France, bought a tiny seven meter Class Mini yacht (游艇), slept under it while she was repairing it, and then she raced it 4,000 kilometres across the Atlantic in 1997, alone for 33 days.Ellen has to learn many things, because sailing single - handed means that she has to be her own captain, electrician, sailmaker, engineer, doctor, journalist, cameraman and cooker, She also has to be very fit, and because of the dangers of sleeping for long periods of time she\'s in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time.And she needs courage. Once, in the middle of the ocean, she had to climb the mast (桅杆) of a boat to repair the sails at four o\'clock in the morning, with 100 kph winds blowing around her. It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It\'s hard to describe how it feels to be up there. It\'s like trying to hold onto a big pole, which for me is just too big to get my arms around, with someone kicking you all the time and trying to shake you off".But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean and having the chance to live this. I just feel lucky to be here."In the Vendee Globe race, Ellen won ____.【单选题】

7、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet and disease. Since 1957 a team of American researchers has monitored the dietary habits and medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns and cancer. Other studies of animals and humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential for the growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver and dairy products like milk, cheese, butter and eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples.In the Western Electric study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in a group of the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even for longtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer and carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. For a smoker, a half-cup of carrots every day might possibly make the difference between life and death.Where is carotene present?【单选题】

A.tomatoes

B.carrots

C.squash

D.all of the above

正确答案:D

答案解析:根据第3段，“维生素A在体内的产生源于胡萝卜素，胡萝卜素在蔬菜、水果中大量存在，包括胡萝卜、菠菜、西葫芦、西红柿和苹果”。因此答案是D。

8、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth\'s surface. That\'s why methane is a major contributor to the planet\'s increasing temperature rise or global warming. Molecule for molecule, methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it\'s no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth\'s atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun\'s heat and warm the planet, life as we know it couldn\'t exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn\'t live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It\'s part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That\'s why we say livestock gas is also a major factor of causing the global warming.Paragraph l ____【单选题】

A.Life of Macroscopic Bacteria in Livestock\'s Rumen

B.Ways to Reduce Methane\'s Heat-trapping Power

C.Agriculture Also Contributes to Increased Concentrations of Methane in the Atmosphere

D.Why Livestock Releases Methane

E.Methane as a Strong Greenhouse Gas

F.Livestock as a Prime Factor of the Greenhouse Effect

正确答案:E

答案解析:本段的第3句点出了“methane\'s heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide. ”

9、Ford(1)Ford\'s great strength was the manufacturing process not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891, although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.(2)The company\'s assembly line alone. threw America\'s Industrial Revolution into overdrive(高速运转）. Instead of having workers put together the entire car, Ford\'s friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford\' s Highland Park plant was humming (嗡嗡作响) along in 1914, the world\'s first automatic conveyor belt could turn out a car every 93 minutes.（3）The same year Henry Ford shocked the world with the $5 a day minimum Wage scheme, the greatest contribution he had ever made. The average Wage in the auto industry then was $2. 34 for a9-hour shift. Ford not only doubled that he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn\'t involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime" and critics everywhere laughed at Ford.(4)But as the wage increased later to daily $10, it proved a critical component of Ford\'s dream to make the automobile accessible to all The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn\'t matter, except for making it possible for more people to buy cars.Ford\'s higher-wage and lower-cost strategy was strongly ____【单选题】

A.criticized by the media

B.the low wage in the auto industry

C.own a car

D.Produce cars in large numbers

E.the 8-hour-shift practice

F.combined technology and market

正确答案:A

答案解析:A填入后整个句子说的是：Ford的高工资、低成本策略受到了传媒的批评。答案可以在第3和第4段中找到。

10、Travel Across AfricaFor six hours we shot through the barren (荒芜的) landscape of the Karoo desert in South Africa. Just rocks and sand and baking sun. Knowing our journey was ending, Daniel and I just wanted to remember all we had seen and done. He used a camera. I used words. I had already finished three notebooks and was into the fourth, a beautiful leather notebook I\'d bought in a market in Mozambique.Southern Africa was full of stories and visions. We were almost drunk on sensations. The roaring (咆哮) of the water at Victoria Falls, the impossible silence of the Okavango Delta in Botswana.And then the other things, dogs in the streets, whole families in Soweto livng in one room, a kilometre from clean water.As we drove towards the setting sun, a quietness fell over us. The road was empty and we hadn\'t seen another car for hours. And as I drove, something caught my eye. Something moved close enough to touch them, to smell their hot breath. I didn\'t know how long they had been there next to us.I shouted to Dan: "Look!" But he was in a deep sleep, his camera lying useless by his feet. They raced the car for a few seconds, then disappeared far behind us, a memory of heroic forms in the red landscape. When Daniel woke up an hour later I told him what had happened."Wild horses?" he said. "Why didn\'t you wake me up, Sophia?""I tried, but they were gone after a few seconds.""Are you sure you didn\'t dream it?""You were the one who was sleeping!""Typical," he said, "The best photos are the ones we never take."We checked into a dusty hotel and slept the sleep of the dead.Daniel and Sophia drove slowly through the barren desert.【单选题】
