单选题Computer monitoring is most often intended to improve efficiency and effectiveness in the workplace, but with good intentions comes the opportunity for abuse by employers and employees alike. Computer Monitoring in the 21st Century written by a futurist is an exceptional observation as to what the future may hold for those people choosing to enter the technological field such as industry, commerce, medicine and science. As computer monitoring increases, there comes a concern for the types of effects it may have in the workplace. The article says: "By the end of the decade, as many as 30 million people may constantly be monitored in their jobs." As computer systems become so sophisticated, this number will drastically increase. As we enter this new age of technology, we must remember that with more power comes more responsibility by employers and employees alike. Knowledge can be used as a weapon or as a tool. For instance, monitoring abuse can be found in the situation of airline agents. The agents discovered that by keeping customers on hold while finishing their work they could gain an extra 5-minute break. In the future, employees who are accustomed to evading the monitoring system may no longer be able to tolerate it. These types of employees may find they can no longer survive the added pressure of not being able to evade the system. While monitoring can add pressure to some employees, it can also be a relief to others. It is a relief to the employee, because it provides information readily at hand. With the use of prompts, acting as reminders to workers, the information needed is passed on efficiently allowing employees to do a better job. However, if prompts are used to tell an employee how much time has been wasted or how bad an employee is doing his job, it could cause the opposite effect. Monitoring can have a positive effect on workers by letting the employees access their own information. In a study, early information about job performance given by a computer is accepted better than a performance rating given by a boss. At this time, monitoring is based on the output of an employee's performance. In the future, there will be more freedom for employees to use their own ideas, therefore making monitoring more effective. One example of monitoring as a weapon is seen when a woman who took an extra minute in the bathroom was threatened with loosing her job. With this added stress she suffered a nervous breakdown. The company insisted that they were not "spying" but were only trying to improve their business. If monitoring is not used correctly, businesses will suffer with increases in operating costs because of increased turnover, absenteeism, medical costs and worker's compensation. Employers who use positive reinforcement with monitoring will guarantee better motivation. Legislation has the potential to help employees with issues of better treatment and the fight to privacy. In the new century, companies that succeeded will be the ones who learn from the past and from the "me boss and you employee" mentality. A good blacksmith can take a hammer and forge a weapon into a tool that can benefit the whole village. Employers are the blacksmiths; employees are the hammers. Monitoring is the tool. It takes both to make a tool to benefit the future.

单选题2 To get from Kathmandu to the tiny village in Nepal, Dave Irvine-Halliday spent more than two days. When he arrived, he found villagers working and reading around battery powered lamps equipped with light-emitting diodes, or LEDs—the same lamps he had left there in 2000. Irvine-Halliday, an American photonics engineer, was not surprised. He chose to use LED bulbs because they are rugged, portable, long-lived, and extremely efficient. Each of his lamps produces a useful amount of illumination from just one watt of pow- er. Villagers use them about four hours each night, then top off the battery by pedaling a generator for half an hour. The cool, steady beam is a huge improvement over lamps still common in developing countries. In fact, LEDs have big advantages over familiar incandes cent (白炽的) lights as well--so much so that Irvine-Halliday expects LEDs will eventual ly take over from Thomas Edison's old lightbulb as the world's main source of artificial il lumination. The dawn of LEDs began about 40 years ago, but early LEDs produced red or green glows suitable mainly for displays in digital clocks and calculators. A decade ago, engineers invented a semiconductor crystal made of an aluminum compound that produced a much brighter red light. Around the same time, a Japanese engineer developed the first practical blue LED. This small advance had a huge impact because blue, green, and red LEDs can be combined to create most of the colors of the rainbow, just as that in a color television picture. These days, high-intensity color LEDs are showing up everywhere such as the traffic lights. The reasons for the rapid switchover are simple. Incandescent bulbs have to be re placed annually, but LED traffic lights should last five to yen years. LEDs also use 80 to 90 percent less electricity than the conventional signals they replace. Collectively, the new traffic lights save at least 400 million kilowatt-hours a year in the United States. Much bigger savings await if LEDs can supplant Mr. Edison's bulb at the office and in the living room. Creating a white-light LED that is energy-saving, cheap and appealing has proved a tough engineering challenge. But all the major lightbulb makers—including Gener al Electric, Philips, and Osram-Sylvania—are teaming up with semiconductor manufactur ers to make it happen.

单选题"I got cancer in my prostate." Detective Andy Sipowicz of the fictional 15th Precinct, a stoic, big bear of a man, is clearly in a world of pain in a 1998 episode of NYPD Blue . The story line deals not only with cancer but also with medical screw-ups, hospital indignities and physician arrogance. The malapropism (Andy, of course, meant "prostate") is about the only medical detail the show got wrong—and it was deliberate, in keeping with Sipowicz"s coarse but tenderhearted character. Television, which can still depict death as an event akin to fainting, is beginning to try harder to get its health information right. And a handful of foundations and consultants are working to get the attention of writers, producers and assorted Hollywood moguls, trying to convince them that, in the area of medicine, the truth is as compelling as fiction. The stakes are high. Surveys show a surprising number of Americans get much of their basic health information not from their doctors, not even from newspapers or news magazines, but from entertainment television. A survey by the federal Centers for Disease Control and Prevention found that among people who watch soap operas at least twice a week—more than 38 million people—about half learned something about disease and its prevention from the daytime serials. Some 7 percent actually visited a doctor because of something they viewed. Certain television shows are naturals for health education. The Clinton administration has been quick to recognize the potency of the entertainment media as a health promoter. Secretary Donna Shalala, whose Department of Health and Human Services educates the public through traditional brochures and public service announcements, has offered TV writers the sources of her department to help them ensure accuracy. "Entertainment television reaches the hearts and minds of millions of Americans," she told U.S. News. "In recent years, I have challenged television talk-show hosts, writers, and producers—as professionals, parents, and citizen—to use this incredible power to help Americans get accurate public health information."

单选题{{B}}Directions: {{/B}}Read the following passages, decide on the best one of the choices marked A, B,C, and D for each question or unfinished statement and mark the corresponding letter with a single bar across the square bracket on ANSWER SHEET I.{{B}}Passage One{{/B}} The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in line, the one who lay beside him to the left when they were below. He was a Serere tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta felt badly for having wished sometimes that he might strike the man in the darkness for moaning so steadily in his pain. Staring back at Kunta, the Serere's dark eyes were full of fury and defiance. A whip lashed out even as they stood looking at each other-this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in bis ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with buckets of seawater. A moment later, the stinging saltiness of it was burning in Kunta's wounds, and his screams joined those of others over the sound of the drum and the wheezing thing that had again begun marking time for the chained men to jump and dance for the toubob. Kunta and the Wolof were so weak from their new beating that twice they stumbled, but whip blows and kicks sent them hopping clumsily up and down in their chains. So great was his fury that Kunta was barely aware of the women singing "Toubob fa!" And when he had finally been chained back down in his place in the dark hold, his heart throbbed with a lust to murder toubob. Every few days the eight naked toubob would again come into the stinking darkness and scrape their tubs full of the excrement that had accumulated on the shelves where the chained men lay. Kunta would lie still with his eyes staring bale fully in hatred, following the bobbing orange lights, listening to the toubob cursing and sometimes slipping and t. ailing into the slickness underfoot-so plentiful now, because of the increasing looseness of the men's bowels, that the filth had begun to drop off the edges of the shelves down into the aisleway. The last time they were on deck, Kunta had noticed a man limping on a badly infected leg. This time the man was kept up on deck when the rest were taken back below. A few days later, the women told the other prisoners in their singing that the man's leg had been cut off and that one of the women had been brought to tend him, but that the man had died that night and been thrown over the side. Starting then, when the toubob came to clean the shelves, they also dropped red-hot pieces of metal into pails of strong vinegar. The clouds of acrid steam left the hold smelling better, but soon it would again be overwhelmed by the choking stink. It was a smell that Kunta felt would never leave his lungs and skin. The steady murmuring that went on in the hold whenever the toubob were gone kept growing in volume and intensity as the men began to communicate better and better with one another. Words not understood were .whispered from mouth to ear along the shelves until someone who knew more than one tongue would send back their meanings. In the process, all of the men along each shelf learned new words in tongues they had not spoken before. Sometimes men jerked upward, bumping their heads, in the double excitement of communicating with each other and the fact that it was being done without the toubob's knowledge. Muttering among themselves for hours, the men developed a deepening sense of intrigue and of brotherhood. Though they were of different villages and tribes, the feeling grew that they were not from different peoples or places.

单选题Which of the following was NOT stated in the passage?

单选题Very old people do raise moral problems for almost everyone who comes in contact with them. Their values—this can"t be repeated too often—are not necessarily our values. Physical comfort, cleanness and order are necessarily the most important things. The social services from time to time find themselves faced with a flat with decaying food covered by small worms, and an old person lying alone on bed, taking no notice of the worms. But is it interfering with personal freedom to insist that they go to live with some of their relatives so that they might be taken better care of ? Some social workers, the ones who clear up the worms, think we are in danger of carrying this concept of personal freedom to the point where serious risks are being taken with the health and safety of the old. Indeed, the old can be easily hurt or harmed. The body is like a car, it needs more mechanical maintenance as it gets older. You can carry this comparison right through to the provision of spare parts. But never forget that such operations are painful experiences, however good the results. And at what point should you cease to treat the old body? Is it morally right to try to push off death by pursuing the development of drugs to excite the forgetful old mind and to activate the old body, knowing that it is designed to die? You cannot ask doctors or scientists to decide, because so long as they can see the technical opportunities, they will feel bound to give them a try on the principle that while there"s life, there"s hope. ? When you talk to the old people, however, you are forced to the conclusion that whether age is happy or unpleasant depends less on money or on health than it does on your ability to have sun.

单选题{{B}}Passage 1{{/B}} If you are a fan of science fiction, you've no doubt encountered the term nanotechnology. Yet over the past year also, a series of breakthroughs have transformed nanotech from sci-fi fantasy into a real world. Applied science, in the process, inspired huge investments by business, academia, and government. In industries as diverse as health care, computers, chemicals, and aerospace, nanotech is overhauling production techniques, resulting in new and improved products, some of which may already be in your home or workplace. The inspiration for nanotech goes back to a 1959 speech by the late physicist Richard Feynman, then a professor at the California Institute of Technology, titled "There's Plenty of Room at the Bottom. " Four decades later, Chad Mirkin, a Chemistry professor at Northwestern University's $ 34 million nanotech center, used a nanoscale device to etch most of Feynman's speech onto a surface the size of about 10 tobacco smoke particles. What accounts for the sudden acceleration of nanotechnology? A key breakthrough came in 1990, when researchers at IBM's Almaden Research Center succeeded in rearranging individual atoms at will. Using a device' known as a scanning probe microscope, the team slowly moved 35 atoms to spell the three-letter IBM logo, thus proving Feynman right. The entire Logo was less than three nanometers. Soon, scientists were not only manipulating individual atoms but "spray painting" with them as well. Using a tool known as a molecular beam epitaxy, scientists have learned to create ultra fine films of specialized crystals, built up one molecular layer at a time. This is the technology used today to build read-head components for computer hard drives. The next stage in the development of nanotechnology borrows a page from nature. Building a supercomputer no bigger than a speck of dust might seem an impossible task, until one realizes that evolution solved such problems more than a billion years ago. Living cells contain all sorts of nanoscale motors made of proteins that perform myriad mechanical and chemical functions, from muscle contraction to photosynthesis. In some instances, such motors may be re-engineered, or imitated, to produce products and processes useful to humans. How are these biologically inspired machines constructed? Often, they construct themselves, manifesting a phenomenon of nature known as self assembly. The macromolecules of such biological machines have exactly the right shape and chemical binding preferences to ensure that when they combine they will snap together in predesigned ways. For example, the two strands that make up DNA's double helix match each other exactly, which means that if they are separated in a complex chemical mixture, they are still able to find each other easily.
