单选题 The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleo-ecologist Edward Deevey, the past million years show three momentous changes. The first, a rapid increase in population around one million B. C., followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when, or if technology begins to yield fewer innovations. Of course, the current knowledge revolution may continue without foreseeable end. Either way contrary to popular belief in constant geometric growth--population can be expected in the long mn to adjust to productivity.

单选题When I was walking down the street the other day, I happened to notice a small brown leather wallet lying on the sidewalk. I picked it up and opened it to see if I could find out the owner's name. There was nothing inside it except some change and an old photograph--a picture of a woman and a young girl about twelve years old, who looked like the woman's daughter. I put the photograph back and took the wallet to the police station, where I handed it to the desk sergeant. Before I left, the sergeant took down my name and address in case the owner might want to write and thank me. That evening I went to have dinner with my aunt and uncle. They had also invited a young woman so that there would be four people at the table. Her face was familiar. I was quite sure that we had not met before, but I couldn't remember where I had seen her. In the course of conversation, however, the young woman happened to mention that she had lost her wallet that afternoon. All at once I realized where I had seen her. She was the young girl in the photograph, although she was now much older. She was very surprised, of course, when I was able to describe her wallet to her. Then I explained that I had recognized her from the photograph I had found in the wallet. My uncle insisted on going to the police station immediately to claim the wallet. As the police sergeant handed it over, he said that it was amazing that I had not only found the wallet, but also the person who had lost it.

单选题In 2010, a federal judge shook America's biotech industry to its core. Companies had won patents for isolated DNA for decades--by 2005 some 20% of human genes were patented. But in March 2010 a judge ruled that genes were unpatentable. Executives were violently agitated. The Biotechnology Industry Organisation (BIO), a trade group, assured members that this was just a "preliminary step" in a longer battle. On July 29th they wererelieved, at least temporarily. A federal appeals court overturned the prior decision, ruling that Myriad Genetics could indeed hold patents to two genes that help forecast a woman' s risk of breast cancer. The chief executive of Myriad, a company in Utah, said the ruling was a blessing to firms and patients alike. But as companies continue their attempts at personalised medicine, the courts will remain rather busy. The Myriad ease itself is probably not over. Critics make three main arguments against gene patents: a gene is a product of nature, so it may not be patented; gene patents suppress innovation rather than reward it; and patents' monopolies restrict access to genetic tests such as Myriad' s. A growing number seem to agree. Last year a federal task-force urged reform for patents related to genetic tests. In October the Department of Justice filed a brief in the Myriad case, arguing that an isolated DNA molecule "is no less a product of nature." than are cotton fibres that have been separated from cotton seeds. " Despite the appeals court' s decision, big questions remain unanswered. For example, it is unclear whether the sequencing of a whole genomeviolates the patents of individual genes within it. The case may yet reach the Supreme Court. As the industry advances, however, other suits may have an even greater impact. Companies are unlikely to file many more patents for human DNA molecules--most are already patented or in the public domain. Firms are now studying how genes interact, looking for correlations that might be used to determine the causes of disease or predict a drug' s efficacy" Companies are eager to win patents for "connecting the dots," explains Hans Sauer, a lawyer for the BIO. Their success may be determined by a suit related to this issue, brought by the Mayo Clinic, which the Supreme Court will hear in its next term. The BIO recently held a convention which included sessions to coach lawyers on the shifting landscape for patents. Each meeting was packed.

单选题{{B}}21-25{{/B}} Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away—straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spot-spray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks? remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

单选题{{B}}Text 3{{/B}} Asia's real boat-rocker is a growing China, not Japan, a senior American economist observed. There is so much noise surrounding and emanating from the world's miracle economy that it is becoming cacophonous. In Washington, DC, the latest idea is that China is becoming too successful, perhaps even dangerously so: while Capitol Hill resounds with complaints of trade surpluses and currency manipulation, the Pentagon and sundry think-tanks echo to a new drumbeat of analysts worrying about China's 12.6% annual rise in military spending and about whether it might soon have the ability to take pre-emptive military action to force Taiwan to rejoin it. So it may be no coincidence that for three consecutive weekends the streets of big Chinese cities have been filled with the sounds of demonstrators marching and rocks being thrown, all seeking to send a different message: that Japan is the problem in Asia, not China, because of its wanton failure to face up to its history; and that by cosying up to Japan in security matters, America is allying with Asia's pariah. Deafness is not the only risk from all this noise. The pressure towards protectionism in Washington is strong, and could put in further danger not only trade with China but also the wider climate for trade liberalisation in the Doha round of the World Trade Organisation (WTO). So far words have been the main weapons used between China and Japan, but there is a chance that nationalism in either or both countries could lead the governments to strike confrontational poses over their territorial disputes in the seas that divide them, even involving their navies. And the more that nationalist positions become entrenched in both countries but especially China, the more that street protests could become stirred up, perhaps towards more violence. All these issues are complex ones and, as is often the case in trade and in historical disputes, finding solutions is likely to be far from simple. A revaluation of the yuan, as demanded in Congress, would not re-balance trade between America and China, though it might help a little, in due course. A "sincere" apology by Japan for its wartime atrocities might also help a little, but it would not suddenly turn Asia's natural great-power rivals into bosom buddies. For behind all the noise lies one big fact: that it is the rise of China, not the status or conduct of Japan, that poses Asia's thorniest questions.

单选题Text 3 If sustainable competitive advantage depends on work-force skills, American firms have a problem. Human-resource management is not traditionally seen as central to the competitive survival of the firm in the United States. Skill acquisition is considered an individual responsibility. Labor is simply another factor of production to be hired-rented at the lowest possible cost-much as one buys raw materials or equipment. The lack of importance attached to human-resource management can be seen in the corporate hierarchy. In an American firm the chief financial officer is almost always second in command. The post of head of human-resource management is usually a specialized job, off at the edge of the corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive Officer(CEO). By way of contrast, in Japan the head of human-resource management is central-usually the second most important executive, after the CEO, in the firm's hierarchy. While American firms often talk about the vast amounts spent on training their work forces, in fact they invest less in the skills of their employees than do either Japanese or German firms. The money they do invest is also more highly concentrated on professional and managerial employees. And the limited investments that are made in training workers are also much more narrowly focused on the specific skills necessary to do the next job rather than on the basic background skills that make it possible to absorb new technologies. As a result, problems emerge when new breakthrough technologies arrive. If American workers, for example, take much longer to learn how to operate new flexible manufacturing stations than workers in Germany (as they do), the effective cost of those stations is lower in Germany than it is in the United States. More time is required before equipment is up and running at capacity, and the need for extensive retraining generates costs and creates bottlenecks that limit the speed with which new equipment can be employed. The result is a slower pace of technological change. And in the end the skills of the population affect the wages of the top haft. If the bottom half can't effectively staff the processes that have to be operated, the management and professional jobs that go with these processes will disappear.

单选题Learning disabilities are very common. They affect perhaps 10 percent of all children. Four times as many boys as girls have learning disabilities. Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized. You cannot look at a child and tell if he or she has a learning disability. There is no outward sign of the disorder. So some researchers began looking at the brain itself to learn what might be wrong. In one study, researchers examined the brain of a learning-disabled person who had died in an accident. They found two unusual things. One involved cells in the left side of the brain, which control language. These cells normally are white. In the learning-disabled person, however, these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been. The nerve cells were mixed together. The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind proposed that learning disabilities resulted mainly from problems in the left side of the brain. He believed this side of the brain failed to develop normally. Probably, he said, nerve cells there did not connect as they should. So the brain was like an electrical device in which the wires were crossed. Other researches did not examine brain tissue. Instead, they measured the brain's electrical activity and made a man of the electrical signals. Frank Duffy experimented with this techniques at Children's Hospital Medical Center in Boston. Doctor Duffy said his research is evidence that reading disabilities involve damage to wide area of the brain, not just the left side.

单选题{{B}}练习十五{{/B}} It's almost the end of summer for the first annual contest to choose the best operating monopoly in America. Five contestants are selected. Each exhibits fine monopolistic characteristics and is worthy of serious consideration for the award. The U.S. Postal Service claims to be the longest-running monopoly and has the distinction of having its control over First Class mail prescribed by the Constitution. The monopoly has preserved large flows of revenues and high wage rates despite studies showing that private companies could carry the mail more efficiently at much lower cost. On the other hand, the position of the Postal Service has been eroded: first, by successful competition on package delivery; second, by the recent entry of express delivery services; and third, and potentially most damaging, by the introduction of the fax machine. Since faxes are bound to supplant(取代) a substantial fraction of First Class letters, the failure to get Congress to classify a fax as First Class mall and, hence, the exclusive domain of the post office shows a remarkable loss of political muscle. Thus, despite past glories, it is hard to be sanguine(乐观的) about the long-term prospects of the post office as a flourishing monopoly. OPEC was impressive in generating billions of dollars for its members. To understand the functioning of this cartel(卡特尔) it's important to sort out the good guys from the bad. Saudi Arabia and Kuwait have typically held oil production below capacity and thereby kept prices above the competitive level. While Libya and Iraq have produced as much as they could and thereby kept prices low. The former were responsible for the vast expansion of oil revenues. But unfortunately, these countries could not keep the other OPEC members in line and were also able to exclude new producers or prevent conservation by consumers. Most cable TV companies have government-issued licenses that keep competitors out. Thus, this business supports the hypothesis that private monopolies aren't sustainable for long unless they have the weight of government behind them. The rapid escalation of prices and the limitations on services seem, however, to be getting customers and their congressional representatives progressively more annoyed. Thus, it would not be surprising if legislative action leads soon to a deterioration of the cable companies' monopoly power. Officials of Ivy League universities have been able to meet in semi-public forums to set rules that determine prices of admission as a function of applicant characteristics, especially financial resources. The universities have more or less successfully applied a high moral tone to the process: Rich applicants are charged more than the competitive price for schooling in order to subsidize(补贴) the smart poor, but it is unclear why this subsidy should come from the smart rich rather than from taxpayers in general. In any event, the universities' enviable cartel position has been damaged by the unenlightened Justice Department. 'Since most of the universities involved have agreed to stop these practices, it may be that future prices for private higher education will come closer to being competitively determined. The final contestant, the NCAA, has been remarkably successful in holding down "salaries" paid to college athletes. It would be one thing merely to collude to determine price ceilings, but the NCAA has also managed to monopolize all the moral arguments. The NCAA has the much more difficult task of defending a policy that prevents many poor individuals from earning money. Incredibly, this defense has been so successful that it has even allowed the organization to maintain the moral high ground. When the NCAA maintains its cartel by punishing schools that violate the rules, almost no one doubts that the evil entities are the schools or people who paid the athletes, rather than the cartel enforcers who prevented from getting paid: Given this extraordinary balancing act, the decision of the panelists was straightforward and the NCAA is the clear and deserving winner of the first annual prize for the best monopoly in America.
