第6题：Whether you think the human story begins in a garden in Mesopotamia known asEden, or in present-day eastAfrica, it is clear that human beings did not start life as an urban creature. Man’s habitat at the outset was dominated by the need to find food, and hunting and gathering were rural pursuits. Not until around 11,000 years ago, did he start building anything that might be called a village. It took another 6000 years for cities of more than 100,000 people to develop. In terms of human history this may seem a welcome development. It would be questionable to say that nothing of consequence has ever come out of the countryside. The wheel was presumably a rural invention.Even city-dwellers need bread as well as circuses.And ifDr. Johnson and Shelley were right to say that poets are the true legislators of mankind, then all those hills and lakes and other rural delights must be given credit for inspiring them. But the rural contribution to human progress seems slight compared with the urban one.Cities’ development is synonymous with human development. The first villages came with the emergence of agriculture and the domestication of animals: people no longer had to wander but could instead draw together in settlements, allowing some to develop particular skills.After a while the farmers could produce surpluses, and the various products could be exchangeD、 Living together meant security.But people also drew together for the practical advantages of being in a particular place: by a river or spring, on a defensible hill or peninsula, next to an estuary (the mouth of a river) or other source of fooD、Also important, argue historians, was a settlement’s capacity to draw people to it as a meeting-place, often for sacred or spiritual purposes. Graves, groves, even caves might become places for ceremonies and rituals. Man did not live by bread alone. But bread, in the broadest sense, was important. People came to cities not just to worship but to trade and the goods they bought and sold were not just farm products but the manufactures of urban craftsmen and skilled workers. The city became a centre of exchange, both of goods and of ideas, and so it also became a centre of learning, and innovation. Cities were much more than all of this, of course, and they were not all the same.As they developed, some were most notable for their religious role, as the hub of an empire, as centres of administration, political development, learning, or commerce. Some flourished, some died, their longevity depending on factors as varied as conquest, plague, misgovernment or economic collapse. Which of the following could best summarize the passage [A] The city rises; the country falls—the history of human’s living places. [B] From hunting/gathering to exchanging—the history of city functions. [C] From villages to cities—the history of urbanity. [D] Isolated, country; united, urban—how countryside and cities differ.

第9题：One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in NorthAmerica enjoy, simply because the world does not contain enough iron ore, protein, petroleum, and so on.At the same time, we in the United States have continued to pursue super affluence as though there were no limits on how much we could consume. We make up 6 percent of the world’s people; yet we consume one-third of the world’s resources. As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter.But as our resources come more and more from the outside world, "outsiders" are going to have some say over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources. AsAmericans consuming such a disproportionate share of the world’s resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine’ the presumed link between our level of well-being and the level of material goods consumeD、If you have only one crust of bread and get another crust of bread, your well-being is greatly enhanceD、But if you have a loaf of bread, then an additional crust of bread doesn’t make that much difference. In the eyes of most of the world today,Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we’re going to have to answer, whether we’re trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch. The prospect of a scarcity of, and competition for, the world’s resources requires that we reexamine the way in which we relate to the rest of the worlD、It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries. We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them. The writer warnsAmericans that ______. A、their excessive consumption has caused world resource exhaustion B、they are confronted with the problem of how to obtain more material goods C、their unfair share of the world’s resources should give way to proper division among countries D、they have to discard their cars for lack of fossil fuel in the world

第10题：To paraphrase 18th-century statesmanEdmundBurke, "all that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from of is tested in animals--no meat, no fur, no medicines.Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes."Asked what will happen when epidemics return, she said, "Don’t worry, scientists will find some way of using computers." Such well-meaning people just don’t understanD、 Scientists must communicate their message to the public in a compassionate, understandable way--in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother’s hip replacement, a father’s bypass operation, a baby’s vaccinations, and even a pet’s shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as StephenCooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress. From the passage we learn that StephenCooper is ______. A、a well-known humanist B、a medical practitioner C、an enthusiast in animal rights D、a supporter of animal research

第13题：Passage 8 New technology links the world as never before. Our planet has shrunk. It’s now a "global village" where countries are only seconds away by fax or phone or satellite link.And, of course, our ability to benefit from this high-tech communications equipment is greatly enhanced by foreign language skills. Deeply involved with this new technology is a breed of modem business people who have a growing respect for the economic value of doing business abroaD、In modem markets, success overseas often helps support domestic business efforts. Overseas assignments are becoming increasingly important to advancement within executive ranks. The executive stationed in another country no longer need fear being "out of sight and out of minD、" He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroaD、If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to cope back in the United States where cross-cultural considerations and foreign language issues are becoming more and more prevalent. Thanks to a variety of relatively inexpensive communications devices with business applications, even small businesses in the United States are able to get into international markets. English is still the international language of business.But there is an ever-growing need for people who can speak another language.A、second language isn’t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal. The employee posted abroad who speaks the country’s principal language has an opportunity to fast-forward certain negotiations, and can have the cultural insight to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign clients over the telephone or by fax machine is an obvious asset to the firm. What is the author’s attitude toward high-tech communications equipment A、Critical.B、PrejudiceD、C、Indifferent.D、Positive.

第15题： Text 4 For about three centuries we have been doing science, trying science out, using science for the construction of what we call modern civilization.Every indispensable item of contemporary technology, from canal locks to dial telephone-to penicillin, was pieced together to form the analysis of data provided by one or another series of scientific experiments. Three hundred years seems a long time for testing a new approach to human inter-living, long enough to settle back for critical appraisal of the scientific method, maybe even long enough to vote on whether to go no with it or not. There is an argument. Voices have been raised in protest since the beginning, rising in pitch and violence in the nineteenth century during the early stages of the industrial revolutions, summoning urgent crowds into the streets any day on the issue of nuclear energy. Give it back, say some of the voices, it doesn’t really work, we’ve tried it and it doesn’t work, go back three hundred years and start again on something else less chancy for the race of man. The principal discoveries in this century, taking all in all, are the glimpses of the depth of our ignorance about nature. Things that used to seem clear and rational, matters of absolute certainty—Newtonian mechanics, for example—have slipped through our fingers, and we are left with a new set of gigantic puzzles, cosmic uncertainties, ambiguities. Some of the laws of physics are amended every few years, some are canceled outright, and some undergo revised versions of legislative intent as if they were acts ofCongress. Just thirty year ago we call it a biological revolution when the fantastic geometry of theDNA、molecule was exposed to public view and the linear language of genetics was decodeD、For a while, things seemed simple and clear, the cell was a neat little machine, a mechanical device ready for taking to pieces and reassembling, like a tiny watch.But just in the last few years it has become almost unbelievably complex, filled with strange parts whose functions are beyond today’s imagining. It is not just that there is more to do; there is everything to do. What lies ahead, or what can lie ahead if the efforts in basic research are continued, is much more than the conquest of human disease or the improvement of agricultural technology of the cultivation of nutrients in the seA、As we learn more about fundamental processes of living things in general we will learn more about ourselves. The principal discovery in this century shows man has______.A．lost many scientific discoveries B、overthrown Newton’s laws of physics C．solved a new set of gigantic puzzles D．given up some of the once accepted theories

第16题：September 11 should have driven home a basic lesson for theBush administration about life in an interconnected world: misery abroad threatens security at home. It is no coincidence that OsamaBin Laden found warm hospitality in the Taliban’sAfghanistan, whose citizens were among the most impoverished and oppressed on earth. If the administration took this lesson seriously, it would dump the rules of realpolitik that have governed U.S. foreign aid policy for 50 years. Instead, it is pouring money into an ally of convenience, Pakistan, which is ultimately likely to expand the ranks of anti-American terrorists abroaD、 To enlist Pakistan in the fight against the Taliban, theBush administration resurrected theCold War tradition of propping up despotic military regimes in the name of peace and freedom. Its commitment of billions of dollars to Pakistan since September 11 will further entrench the sort of government that has made Pakistan both a development failure and a geopolitical hotspot for decades. Within Pakistan, the aid may ultimately create enough angry young men to make upA1 Qaeda’s losses inAfghanistan. In SouthAsia as a whole, the cash infusion may accelerate a dangerous arms race with Indi A、 Historically, the U.S. government has cloaked aid to allies such as Pakistan in the rhetoric of economic development.As aCold War ally, Pakistan received some $ 37 billion in grants and loans from the West between 1960 and 1990, adjusting for inflation.And since September 11, the U.S. administration has promised more of the’ same. It has dropped sanctions imposed after Pakistan detonated a nuclear bomb in 1998, pushed through a $1.3 billion IMF loan for Pakistan, and called for another $2 billion from the WorldBank and theAsianDevelopmentBank. TheBush administration is also, ironically, pressing allies to join it in canceling or rescheduling billions of dollars of old (and failed) loans that were granted in past decades in response to similar arm-twisting. Despite--even because of--all this aid, Pakistan is now one of the most indebted, impoverished, militarized nations on earth. The causes of Pakistan’s poverty are sadly familiar. The government ignored family planning, leading to population expansion from 50 million in 1960 to nearly 150 million today, for an average growth rate of 2.6 percent a year. Foreign aid meant to pave rural roads went into unneeded city highways--or pockets of top officials.And the military grew large, goaded by a regional rivalry with India that has three times bubbled into war. The result is a government that, as former WorldBank economist WilliamEasterly has observed, "cannot bring off a simple and cheap measles (麻疹) vaccination (预防接种) program, and yet...can build nuclear weapons.\ By saying "It is no coincidence that OsamaBin Laden found warm hospitality in the Taliban’sAfghanistan," the author means ______. A、OsamaBin Laden and Taliban are good friends B、America’s foreign policy is one of the sources of the misery inAfghanistan C、it is not difficult forBin Laden to find warm hospitality inAfghanistan D、OsamaBin Laden is the source of misery abroad

第19题：When theAmerican economy was running full tilt two years ago, few places were as breathlessly delighted as Seattle. Its port was thronged with ships bringing goods fromAsi A、TheBoeingCompany could barely keep up with demand for its airliners. Microsoft was hiring hordes of software engineers.After each rain shower, another Internet millionaire sprang up. Here was a city that had it all--OldEconomy, NewEconomy, Not-Yet-InventedEconomy. Now it has all gone sour. The past 12 months have been a non-stop succession of disappointments.Boeing’s headquarters decamped toChicago. The Internet economy popped alike a balloon in a nail factory, taking with it once promising local ventures such as Homegrocer.com and leaving can’t-possibly-miss companies such as drugstore.com barely hanging on.And an already troubledBoeing was hit even harder after September 11th both by a steep drop in airliner orders and by losing a $ 200 billion Joint Strike Fighter contract to Lockheed Martin. Washington State, battered by what is happening in Seattle, now has the highest unemployment rate in the United States--6.6% compared with 5.4% in the country as a whole. Right behind it is next-door Oregon, another former boom state, with 6.5% of its workforce out of a job, the country’s second worst figure. In Oregon, manufacturing’s collapse has caused the loss of nearly 30,000 jobs in a year, those hit range from Freightliner, a maker of heavy lorries, to high-tech companies such as Intel and Fujitsu. What makes the current plunge so painful is that every part of the economy seems to have stepped into an open manhole at the same time. Three years ago, whenBoeing began to remove more than 20,000 people thatBoeing expects to lay off by the middle of 2002 have to compete with unemployed workers not just from the high-tech industry but from construction work and even the retail sector. Portland now has more jobless than the other parts of Oregon: the opposite of how things were years ago. Even worse, the Pacific north west’s downturn, as well as being deeper than the rest of the country, may also last longer. One reason for fearing this isBoeing’s continuing woes. NowadaysBoeing accounts for less than 5% of employment in the Seattle area, down from 9% two decades ago.But it remains the foundation on which the rest is built. Its network of suppliers and subcontractors gives it a far stronger multiplier effect than, say, Microsoft, which is more an island of prosperity than a center of weB、The chances are thatBoeing will not really bounce back until the assumed revival in air travel persuades airline companies to start buying plenty of aircraft again.And that may not be until 2003. The sentence "After each rain shower, another Internet millionaire sprang up" (Paragraph 1) means ______. A、many people get rich quickly and easily with the NewEconomy B、it takes only the time between showers for someone to become boss C、Seattle’s development is sudden like rain showers D、Seattle has as many business millionaires as its rain showers
