单选题{{B}}Passage 3{{/B}} The single greatest shift in the history of mass-communication technology occurred in the 15th century, and was well described by Victor Hugo in a famous chapter of Notre Dame de Paris. It was a Cathedral. On all parts of the giant building, statuary and stone representations of every kind, combined with huge widows of stained glass, told the stories of the Bible and the saints, displayed the intricacies of Christian theology, adverted to the existence of highly unpleasant demonic winged creatures, referred diplomatically to the majesties of political power, and in addition, by means of bells in bell towers, told time for the benefit of all of Pairs and much of France. It was an awesome engine of communication. Then came the transition to something still more awesome. The new technology of mass communication was portable, could sit on your table, and was easily replicable, and yet, paradoxically, contained more information, more systematically presented, than even the largest of cathedrals. It was the printed book. Though it provided no bells and could not tell time, the over-all superiority of the new invention was unmistakable. In the last ten or twenty years, we have been undergoing a more or less equivalent shift--this time to a new life as a computer-using population. The gain in portability, capability, ease, orderliness, accuracy, reliability, and information-storage over anything achievable by pen scribbling, typewriting, and cabinet filing is recognized by all. The progress for civilization is undeniable and, plainly, irreversible. Yet, just as the book's triumph over the cathedral divided people into two groups, one of which prospered, while the other lapsed into gloom, the computer's triumph has also divided the human race. You have only to bring a computer into a room to see that some people begin at once to buzz with curiosity and excitement, sit down to conduct experiments, ooh and ah at the boxes and beeps, and master the use of the computer or a new program as quickly as athletes playing a delightful new game. But how difficult it is--how grim and frightful!--for the other people, the defeated class, whose temperament does not naturally respond to computers. The machine whirries and glows before them and their faces twitch. They may be splendidly educated, as measured by book-reading, yet their instincts are all wrong, and no amount of manual-studying and mouse-clicking will make them right. Computers require a sharply different set of aptitudes, and, if the aptitudes are missing, little can be done, and misery is guaranteed. Is the computer industry aware that computers have divided mankind into two new, previously unknown classes, the computer personalities and the non-computer personalities? Yes, the industry knows this. Vast stuns have been expended in order to adapt the computer to the limitations of non-computer personalities. Apple's Macintosh, with its zooming animations and pull-down menus and little pictures of life folders and watch faces and trash cans, pointed the way. Such seductions have soothed the apprehensions of a certain number of the computer-averse. This spring, the computer industry's efforts are reaching a culmination of sorts. Microsoft, Bill Gates' giant corporation, is to bring out a program package called Microsoft Bob, designed by Mr. Gates' wife, Melinda French, and intended to render computer technology available even to people who are openly terrified of computers. Bob's principle is to take the several tasks of operating a computer, rename them in a folksy style, and assign to them the images of an ideal room in ideal home, with furniture and bookshelves, and with chummy cartoon helpers ("Friends of Bob") to guide the computer user over the rough spots, and, in that way, simulate an atmosphere that feels nothing like computers.

单选题{{B}}Passage Three{{/B}} A new biotechnology procedure that could become commercially available in as little as two to four years is "transgenesis", which permits scientists to create an animal with specific traits by adding, removing, inactivating, or repairing genes in an embryo. The additional genes can come from any source. For example, if a gene of interest occurs in mosquitoes—say, one that codes for resistance to a certain disease—it can be removed and places in the embryo of a farm animal. The several strains of commercially useful transgenic farm animals that will probably emerge in the next few years could include leaner pigs, poultry resisting to influenza or other deadly diseases, sheep with wool that is easier to wash, and goats that produce valuable pharmaceuticals in their milk. The simplest way to make transgenic animals is to inject a gene into a one-cell embryo and then implant the embryo in another animal. Under the right conditions, the new gene joins one of the embryo's strands of genes. Each cell created as the embryo divides gets a copy of the new gene. An alternative technique is to incorporate the gene into a type of virus known as a retrovirus that has bean modified so it cannot reproduce itself after entering a cell. The virus, which cannot cause disease, delivers the gene to the cell's nucleus- Often this method is better than gene injection because a retrovirus always delivers just one gene, and the gene is always undamaged and complete.

单选题（清华大学2008年试题） The changes in globally averaged temperature that have occurred at the Earth's surface over the past century are similar in size and timing to those【1】by models that take into account the combined influences of human factors and solar variability. To【2】the question of attribution requires the【3】of more powerful and complex methods, beyond the use of global averages alone. New studies have focused on【4】maps or patterns of temperature change in【5】and in models. Pattern analysis is the cli-matologically equivalent of the more comprehensive tests in the medical analogy mentioned【6】, and makes it possible to achieve more definitive【7】of observed climate changes to a particular cause or causes. The expected influence of human activities is thought to be much more complex than uniform warming over the entire surface of the Earth and over the whole【8】cycle. Patterns of change over space and time therefore provide a more powerful【9】technique. The basic idea【10】pattern-based approaches is that different【11】causes of climate change have different characteristic patterns of climate response or fingerprints. Attribution studies seek to【12】a fingerprint match between the patterns of climate change【13】by models and those actually observed. The most recent assessment of the science suggests that human activities have led to a discernible【14】on global climate and that these activities will have an increasing influence on future climate. The burning of coal, oil and natural gas, as well as various agricultural and industrial practices, are【15】the composition of the atmosphere and contributing to climate change. These human activities have led to increased atmospheric【16】of a number of greenhouse gases, including carbon dioxide, methane and so on in the lower atmosphere. Human activities, such as the burning of fossil, have also increased the【17】of small particles in the atmosphere. These particles can change the【18】of energy that is absorbed and reflected by the atmosphere. They are also believed to modify the【19】of air and clouds, changing the amount of energy that they absorb and reflect.

It is likely that the net effect of these small particles is to cool the climate and to partially offset the warming of increasing concentrations of greenhouse gases.

单选题In 1993, a mall security camera captured a shaky image of two 10-year-old boys leading a much smaller boy out of a Liverpool, England, shopping center. The boys lured Jarfies Bulger, away from his mother, who was shopping, and led him on a long walk across town. The excursion ended at a railroad track. There, inexplicably, the older boys tortured the toddler, kicking him, smearing paint on his face and pummeling him to death with bricks before leaving him on the track to be dismembered by a train. The boys, Jon Venables and Robert Thompson, then went off to watch cartoons. Today the boys are 18-year-old men, and after spending eight years in juvenile facilities, they have been deemed fit for release, probably this spring. The dilemma now confronting the English justice system is how to reintegrate the notorious duo into a society that remains horrified by their crimes and skeptical about their rehabilitation. Last week Judge Elizabeth Butler-Sloss decided the young men were in so much danger that they needed an unprecedented shield to protect them upon release. For the rest of their lives, Venables and Thompson will have a right to anonymity. All English media outlets are banned from publishing any information about their whereabouts or the new identities the government will help them establish. Photos of the two or even details about their current looks are also prohibited. In the U. S., which is harder on juvenile criminals than England, such a ruling seems inconceivable. "We're clearly the most punitive in the industrialized world," says Laurence Steinberg, a Temple University professor who studies juvenile justice. Over the past decade, the trend in the U. S. has been to allow publication of ever more information about underage offenders. U. S. courts also give more weight to press freedom than English courts, which, for example, ban all video cameras. But even for Britain, the order is extraordinary. The victim's family is enraged, as are the ever eager British tabloids. "What right have they got to be given special protection as adults?" asks Bulger's mother Denise Fergus. Newspaper editorials have insisted that citizens have a right to know if Venables or Thompson move in next door. Says conservative Member of Parliament Humfrey Malins: "It almost leaves you with the feeling that the nastier the crime, the greater the chance for a passport to a completely new life./

单选题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 arid 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 all 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 must 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.
