单选题Innovation. It's what got us through the Dark Ages. But over the years, instead of moving forward, some scientists and inventors have taken a few steps back. This article is dedicated to all the men and women who knew they'd never find a cure for the common cold, so they aimed much, much lower. Here are some of the winners. PEACE PRIZE—researchers from the University of Bern, Switzerland, for determining which hurts mor—being smashed over the head with a full bottle of beer or with an empty bottle. An inherent problem in an experiment of this nature is finding volunteers who will agree to be brained with a beer bottle in the name of science. The scientists overcame this obstacle by dropping steel balls onto full and empty beer bottles. They found that the empties were stronger than their full brethren because the gas pressure from the liquid produces additional strain on the glass. Needless to say, full or not, beer bottles can cause a whole lot of hurt, which is why the scientists advocate prohibiting them "in situations that involve risk of human conflicts." VETERINARY MEDICINE PRIZE—researchers from Newcastle University, the United Kingdom: for showing that cows that have names give more milk than cows that are nameless. It turns out our attitudes make a difference. Being friendly and remembering a cow's name can increase milk yield by 258 liters a year. This came as no surprise to farmers, one of whom told the researchers that cows "hurt and love like anyone else." BIOLOGY PRiZE—researchers from Kitasato University Graduate School of Medical Sciences in Japan, for demonstrating that kitchen refuse can be reduced by more than 90 percent by using an enzyme (酶)-producing bacteria extracted from the waste of giant pandas. While this has potential applications—reducing garbage and waste—it still raises the question. How did it dawn on someone to try this experiment? And, of course, if one of your aims in ridding yourself of garbage is to get rid of the bad smell, adding panda waste to it is not likely to help.

单选题 In 1977 Irene Pepperberg did something very bold. At a time when animals still were considered automatic in behavior, she set out to find out what was on another creature's mind by talking to it. At that time, many scientists believed animals were incapable of any thought. They were simply machines, robots programmed to react to stimuli but lacking the ability to think or feel. "That's why I started my studies with Alex," Pepperberg said. Alex was a one-year-old African gray parrot Pepperberg bought in a Chicago pet store. She let the store's assistant pick him out because she didn't want other scientists saying later that she'd intentionally chosen an especially smart bird for her work. Given that Alex's brain was the size of a shelled walnut, most researchers thought Pepperberg's interspecies communication study would fail. Under Pepperberg's patient instruction, Alex learned how to use his vocal tract to imitate almost one hundred English words. They were clearly a team-- and because of their work, the notion that animals can think is no longer so fanciful. Since Alex was able to produce a close approximation of the sounds of some English words, Pepperberg could ask him questions about a bird's basic understanding of the world. Of course she couldn't ask him what he was thinking about, but she could ask him about his knowledge of numbers, shapes, and colors. To demonstrate, Pepperberg took a green key and a small green cup from a basket on a shelf. She held up the two items to Alex's eye. "What's same?" she asked. Without hesitation, Alex's said. "Co-lor." "What's different?" Pepperberg asked. "Shape," Alex said. His voice had the digitized sound of a cartoon character. But the words--and what can only be called the thoughts--were entirely his. And, then, as if to offer final proof of the mind inside his bird's brain, Alex spoke up. "Talk clearly!" he commanded, when one of the younger birds Pepperberg was also teaching mispronounced the word green. "Talk clearly!" "They need to be able to distinguish colors to know when a fruit is ripe or unripe," Pepperberg noted. "They need to know the shapes of their enemies. And it helps to have a concept of numbers if you need to keep track of your flock. For a longlived bird, you can't do all of this with instinct; {{U}}cognition{{/U}} must be involved."

单选题Which of the following is NOT true?

单选题 You thought the rising cost of college tuition was bad? Then check out the rising cost of college textbooks. The American Enterprise Institute's Mark Perry has put together a detailed chart showing the notorious, 812 percent rise in the cost of course materials since 1978, as captured in the Bureau of Labor Statistics' consumer price index data. The price of all those Introduction to Sociology and Calculus books have shot up faster than health-care, home prices, and, of course, inflation. Academic publishers will tell you that creating modern textbooks is an expensive, labor-intensive process that demands charging high prices. But as Kevin Carey noted in a recent article, the industry also shares some of the dysfunctions that help drive up the cost of healthcare spending. Just as doctors prescribe prescription drugs they will never have to pay for, college professors often assign titles with little consideration of cost. Students, like patients worried about their health, don't have much choice to pay up, lest they risk their grades. Meanwhile, Carey illustrates how publishers have done just about everything within their power to step up their profits, from bundling textbooks with software that forces students to buy new editions instead of cheaper used copies, to suing a low-cost textbook start-ups over ill-conceived and inadequate copyright claims. And that has consequences for students. According to the National Association of College Stores (NACS), the average college student reports paying about $655 for textbooks and supplies annually, down a bit from $702 four years ago. The NACS credits that fall to its efforts to promote used books along with programs that let students rent rather than buy their texts. But to put that $655 in perspective, consider this: after aid, the average college student spends about $2,900 on their annual tuition, according to the College Board. We're not talking about just another drop in the bucket here. AEI's Perry writes that he's confident open educational resources, made available via the web, will eventually make traditional textbooks obsolete, just as Wikipedia killed off the encyclopedia. The difference is that nobody I know ever had a college professor who said, "If you don't read the encyclopedia, you'll likely fail this class." If we ever want to bring the cost of these books under control, the faculty need to become responsive to the problem.

单选题Although in her teens, the eldest daughter had to quit school to help ______ the family.

单选题Passage Three Bears mostly live alone, except for mothers and their babies, and males and females during mating season. Bears form temporary groups only in exceptional circumstances, when food is plentiful in a small areA. Recent evidence also suggests that giant pandas may form small social groups, perhaps because bamboo is more concentrated than the patchy food resources of other bear species. Other bears may live alone but exist in a social network. A male and female may live in an area partly shared in common—although they tolerate each other, each defends, its range from other bears of the same sex. Male young usually leave their mothers to live in other areas, but female young often live in a range that is commonly shared with that of their mother. The key to a bear's survival is finding enough food to satisfy the energy demands of its large size. Bears travel over huge territories in search of food, and they remember the details of the landscape they cover. They use their excellent memories to return to locations where they have had success finding food in past years or seasons. Most bears are able to climb trees to chase small animals or gain access to additional plant vegetation. The exceptions are polar bears and large adult brown bears—their heavy weight makes it difficult for them to climb trees. Bears that live in regions with cold winters spend the coldest part of the year asleep in sheltered dens, including brown bears, American and Asiatic black bears, and female polar bears. Pregnant females give birth in the winter in the protected surroundings of these dens. After fattening up during the summer and fall when food is abundant, the bears go into this winter home to conserve energy during the part of the year when food is scarce. Winter sleep differs from hibernation (冬眠) in that a bear is easily aroused from sleep. In addition, a bear's body temperature drops only a few degrees in its winter sleep. In contrast, a true hibernator undergoes more extensive changes in bodily functions. For instance, the body temperature of the Arctic ground squirrel drops from 38℃ to as low as -3℃.
