单选题The feared tomahawk was a war axe (1) by Native Americans. A Native American would make one by honing a piece of stone so that (2) had one or two sharp edges, and (3) attaching it to a wooden handle. The young men would spend many hours practicing to become expert (4) the tomahawk's use. It became an excellent weapon. This was especially true when used by a brave (5) . To make a tomahawk, the Native American first had to find a (6) that was the proper shape and weight. Then it had to be attached to a (7) . One way to do this was to bore or burn a hole (8) a wooden stick, then push the stone through it and tie the stone and wood (9) with strips of hide. Another way was to split the wood, force the stone (10) the sides of the split, and finally tie the divided ends of the stick together. The tomahawk could be used for chopping twigs and other rough cutting jobs. However its primary purpose was as a (11) . Normally, the warrior wielded his tomahawk in hand-to-hand combat, swinging it at his enemies in hopes of stunning them, (12) cutting them. On rare occasions it was (13) . But unless the tomahawk was perfectly balanced, tossing it was an extremely poor method of hitting a target. The type of stone use determined how (14) it was.

These were manufactured in Europe for the settlers, (17) for trade with the Native Americans. Some tribes had the (18) of burying their tomahawks in the ground whenever a peace had been declared with their enemies. Presumably, it was this custom (19) gave rise (20) the phrase " to bury the hatchet".

单选题{{B}}Text 2{{/B}} Large, multinational corporations may be the companies whose ups and downs seize headlines. But to a far greater extent than most Americans realize, the economy' s vitality depends on the fortunes of tiny shops and restaurants, neighborhood services and factories. Small businesses, defined as those with fewer than 100 workers, now employ nearly 60 percent of the work force and are expected to generate half of ail new jobs between now and the year 2000. Some 1.2 million small firms have opened their doors over the past six years of economic growth, and 1989 will see an additional 200,000 entrepreneurs striking off on their own. Too many of these pioneers, however, will blaze ahead unprepared. Idealists will overestimate the clamor for their products or fail to factor in the competition. Nearly everyone will underestimate, often fatally, the capital that success requires. Midcareer executives, forced by a takeover or a restructuring to quit the corporation and find another way to support themselves, may savor the idea of being their own boss but may forget that entrepreneurs must also, at least for a while, be bookkeeper and receptionist, too. According to Small Business Administration data,24 of every 100 businesses starting out today are likely to have disappeared in two years, and 27 more will have shut their doors four years from now. By 1995, more than 60 of those 100 start-ups will have folded. A new study of 3,000 small businesses, sponsored by American Express and the National Federation of Independent Business, suggests slightly better odds: Three years after start-up ,77 percent of the companies surveyed were still alive. Most credited their success in large part to having picked a business they already were comfortable in. Eighty percent had worked with the same product or service in their last jobs. Thinking through an enterprise before the launch is obviously critical. But many entrepreneurs forget that a firm' s health in its infancy may be little indication of how well it will age. You mast tenderly monitor its pulse. In their zeal to expand, small-business owners often ignore early warning signs of a stagnant market or of decaying profitability. They hopefully pour more and more money into the enterprise, preferring not to acknowledge eroding profit margins that mean the market for their ingenious service or product has evaporated, or that they must cut the payroll or vacate their lavish offices. Only when the financial well runs dry do they see the seriousness of the illness, and by then the patient is usually too far gone to save. Frequent checks of your firm's vital signs will also guide you to a sensible rate of growth. To snatch opportunity, you must spot the signals that it is time to conquer new markets, add products or perhaps franchise your hot idea.

单选题{{B}}Text 3{{/B}} A pair of dice, rolled again and again, will eventually produce two sixes. Similarly, the virus that causes influenza is constantly changing at random and, one day, will mutate in a way that will enable it to infect billions of people, and to kill millions. Many experts now believe a global outbreak of pandemic flu is overdue, and that the next one could be as bad as the one in 1918, which killed somewhere between 25m and 50m people. Today however, advances in medicine offer real hope that another such outbreak can be contained-if governments start preparing now. New research published this week suggests that a relatively small stockpile of an antiviral drug-as little as 3m doses--could be enough to limit sharply a flu pandemic if the drugs were deployed quickly to people in the area surrounding the initial outbreak. The drug's manufacturer, Roche, is talking to the World Health Organisation about donating such a stockpile. This is good news. But much more needs to be done, especially with a nasty strain of avian flu spreading in Asia which could mutate into a threat to humans. Since the SARS outbreak in 2003 a few countries have developed plans in preparation for similar episodes. But progress has been shamefully patchy, and there is still far too little international coordination. A global stockpile of drugs alone would not be much use without an adequate system of surveillance to identify early cases and a way of delivering treatment quickly, If an outbreak occurred in a border region, for example, a swift response would most likely depend on prior agreements between different countries about quarantine and containment. Reaching such agreements is rarely easy, but that makes the task all the more urgent, Rich countries tend to be better prepared than poor ones, but this should be no consolation to them. Flu does not respect borders. It is in everyone's interest to make sure that developing countries, especially in Asia, are also well prepared. Many may bridle at interference from outside. But if richer nations were willing to donate anti-viral drugs and guarantee a supply of any vaccine that becomes available, poorer nations might be willing to reach agreements over surveillance and preparedness. Simply sorting out a few details now will have lives (and recriminations) later. Will there be enough ventilators, makes and drugs? Where will people be treated if the hospitals overflow? Will food be delivered as normal? Too many countries have no answers to these questions.

单选题It can be inferred from the passage that which of the following presents the greatest danger to diver?

单选题Aimee Hunter, a research psychologist at the University of California, Los Angeles, has long studied individual responses to antidepressants. Being skeptical of the true effectiveness of the drugs, she says she was originally interested in researching the impact of placebos. But over the years, her own data began convincing her otherwise. "I've come to see now, by doing the research myself and spending hours looking at numbers, that the medication is absolutely doing something," Hunter says. In an earlier study that Hunter published in 2009, she and her team used the same QEEG technique on 58 patients, who were given a placebo daily for one week before being randomized to take either placebo or an active drug. Researchers found distinct patterns of brain activity in the patients; not everyone responded to the placebo the same way. "We found that changes in brain function occurring during the first week of placebo predicted who will do well on medication," she says. The region where changes were recorded—in the prefrontal lobe—is thought to be involved in generating expectations. A common explanation for the placebo effect is that the mere anticipation of improvement begets real benefit. But in the case of Hunter's patients, the changes in brain activity predicted actual response to the antidepressant , not to placebo. Intriguingly, in patients who showed the specific brain response associated with antidepressant-related recovery, the most significant improvement was seen in what psychologists call interpersonal sensitivity how people respond to either positive or negative social events. When suffering from depression, patients tend to become inured to positive social cues and oversensitized to negative ones. They may interpret a passerby's frown as being directed at them, for instance, and some research has found that depressed people are more likely to misidentify smiling faces as conveying neutral or negative emotions. The patients who improved with medication in Hunter's study "were less sensitive to rejection and more comfortable with others," she says. Reducing emotional sensitivity—not treating depression per se—is what medications like Prozac, which affect the levels of serotonin in the brain, do best, according to Healy. If that entire class of drugs had been studied and marketed as pills to reduce emotional reactivity rather than depression, he says, "the placebo response would be very small compared to the drug. " Still, treating a patient's oversensitivity does not necessarily help depression. For some people whose illness is marked by social dread and misperceived rejections, reducing that anxiety could be critical. But for someone whose depression is primarily experienced as deep sadness and inability to feel pleasure, blunting emotional sensitivity may do little good. These differences further explain why the drugs may produce such varied individual responses. Evidence suggests that about 80% of people with depression can be helped by drugs, talk therapy or a combination of the two, so although it is critical to figure out which treatments work for which patients, the larger question remains: Why aren't most patients getting good care, and why do we continue to insist that so many of those taking antidepressants don't really need them?

单选题When scientists are trying to understand a particular set of phenomena, they often make use of a "model." A model, in the scientists' sense, is a kind of analogy or mental image of the phenomena in terms of something we are familiar with. One example is the wave model of light. We cannot see light as if it were made up of waves because experiments on light indicate that it behaves in many respects as water waves do. The purpose of a model is to give us a mental or visual picture -- something to hold onto -- when we cannot see what is actually happening. Models often give us a deeper understanding: the analogy to a known system (for instance, water waves in the above example) can suggest new experiments to perform and can provide ideas about what other related phenomena might occur.
