It is now home(中心地,根据地) to the most expensive and ambitious medical technology project ever in Britain, which this year will make the Hammersmith the world's first fully digital hospital. The paper-free office brought about by computerization and modern information technology is familiar to(为……所熟悉) many office workers today. It has taken longer for the same technology to be applied to medical imaging(医学影像学), because of the immense computing power and high cost o the equipment required. But now the Hammersmith is becoming the first hospital in which all imaging data-- X-rays, ultrasonic ,CT and MRI images--are stored not on cumbersome, inflammable films but as digital data on optical discs. The first consequence of this can be seen in the air-conditioned computer room in the new building, where two compact(坚实的,结实的) cabinets each about as tall as a man and 0.6m wide are ready to store every X-ray and scan made at the Hammersmith in the next 16 years on optical discs(光盘). Space saving is the most obvious but not the most important advantage of the digital h6spital. A consultant conducting a clinic with a workstation linked by fibre optics(光纤) to the data store has no need of cumbersome trolleys loaded with patients' X-rays. The new technology considerably reduces the exposure to ionizing (电离的) radiation needed to get pictures doctors need, corresponding to reducing the slight but inevitable health risk that come with repeated X-rays. X-rays record their images on fluorescent(荧光的) plates, lasers read off and store the data and the plates are wiped clean to use again. This requires less radiation than conventional(常规的) imaging. The ability to enhance imaging also reduces the need for extra exposures. Another advantage is that any stored image can be sent to any of the hospital's 138 workstations in four seconds(soon that will come down(降落) to two seconds). Soon it will be possible to send it direct to other hospitals, or to computer screens in GP's(全科医生) clinics. PACS(图像存档通讯系统) is the most expensive single medical technology project ever funded in UK. Most of the money has come from the Department of Health, which has realized that it will benefit patients at the Hammersmith Hospital and those referred from elsewhere, in terms of(按照) better, quicker and safer diagnosis and treatment. Another technique uses radio a belled(用放射性同位素示踪的) white blood cells to guide doctors to the sites of hidden abscesses(脓肿) or other trouble spots. In the most innovative technique of all, interventional(干预的,介入的) radiology, doctors use tiny instruments at the ends of fine catheters(导管), inserted deep into the body under local anaesthetic, to perform a growing amount of microsurgery, viewed by surgeons—and patients if appropriate—in extremely clear detail. Every scrap(碎片,段) of unwanted image is electronically edited off the screen by the computer. The Hammersmith Hospital is also pioneering interventional radiography, in which doctor carry out microsurgery at the same time as they image the patients' organs in minute detail. The blocking or unblocking of arteries to prevent damage due to bleeding or thrombosis(血栓形成) is among the conditions now being treated in this way.

单选题Food The U. S. food supply is the most varied and abundant in the world. Americans spend a smaller share of their disposable income on food than citizens of any other country and choose from an average of 50,000 different food products on a typical outing to the supermarket. In 1994, the fowl supply provided an estimated 3,800 calories per person per day, enough to supply every American with more than one and a half times their average daily energy needs. Given this abundance, few of the Nations resources have traditionally been devoted to measuring or reducing food waste. In recent years, growing concern about hunger, resource conservation, and the environmental and economic costs associated with food waste have raised public awareness of food loss. This in turn has accelerated public and private efforts to make better use of available, food supplies by recovering safe and nutritious food that would otherwise be wasted. Of course, not all food that is lost is suitable for consumption. Some losses like the condemnation of diseased animals at the slaughtering house (屠宰场), or the discard of rotten fruit from the produce shelf at the supermarket are necessary to ensure the safetyand health of the U. S. food supply. Such foods are not recoverable for human use. Likewise, plate fragments are appropriately discarded at eating establishments out of health considerations. In addition, not all food that is lost is economically recoverable. Food recovery efforts are often limited by financial restraints that make it difficult to match recovered food with potential recipients. Nevertheless, large quantities of healthy, edible food are lost at every stage of the marketing system. Example of such losses include meats, bread, and other foods prepared by a restaurant or hotel but never served and the discard of defected or over-ripe .produce, which maybe difficult to sell out for some reasons, but are otherwise nutritious and safe.

单选题Computer Needs Emotion The next big breakthrough in artificial intelligence could come from giving machines not just more logical capacity, but emotional capacity as well. Feeling aren't usually associated with inanimate(无生命的) machines, but Posalind Picard, a professor of computer technology at MIT, believes emotion may be just the thing computes need to work effectively. Computers need artificial emotion both to understand their human users better and to achieve self-analysis and self-improvement, says Picard. "If we want computers to be genuinely intelligent, to adapt to us, and to interact naturally with us, then they will need the ability to recognize and express emotions, to have emotions, and to have what has come to be called emotional intelligence. " Picard says. One way that emotions can help computers, she suggests, is by helping keep them from crashing. Today's computers produce error messages, but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense. A healthy fear of death could motivate a computer to stop trouble as soon as it starts. On the other hand, self-preservation would need to be subordinate to service to humans. It was fear of its own death that promoted RAL, the fictional computer in the film 2002:A Space Odyssey, to extermine (消灭) most of its human associates. Similarly, computers that could "read" their users would accumulate a store of highly personal information about us-not just what we said and did, but what we likely thought and felt. "Emotion not only contributes to a richer quality of interaction, but they directly impact a person's ability to interact in an intelligent way, " Picard says, "Emotional skills, especially the ability to recognize and express emotions, are essential for natural communication with humans. /

单选题Listening Device Provides Landslide Early Warning A device that provides early warning of a landslide by monitoring vibrations in soil is being tested by UK researchers. The device could save thousands of lives each year by warning when an area should be evacuated, the scientists say. Such natural disasters are common in countries that experience sudden, heavy rainfall, and can also be triggered by earthquakes and even water erosion. Landslides start when a few particles of soil or rock within a slope start to move, but the early stages can be hard to spot. Following this initial movement, "Slopes can become unstable in a matter of hours or minutes," says Nell Dixon at Loughborough University, UK. He says a warning system that monitors this movement might be enough to evacuate a block of fiats or clear a road, and save lives. The most common way to monitor a slope for signs of an imminent landslide is to watch for changes in its shape. Surveyors can do this by measuring a site directly, or sensors sunk into boreholes or fixed above ground can be used to monitor the shape of a slope. Slopes can, however, change shape without triggering a landslide, so either method is prone to causing false alarms. Now Dixon"s team has developed a device that listens for the vibrations caused when particles begin moving within a slope. The device takes the form of a steel pipe dropped into a borehole in a slope. The borehole is filled in with gravel around the pipe to help transmit high-frequency vibrations generated by particles within the slope. These vibrations pass up the tube and are picked up by a sensor on the surface. Software analyses the vibration signal to determine whether a landslide may be imminent. The device is currently being tested in a 6-metre-tall artificial clay embankment in Newcastle, UK. Early results suggest it should provide fewer false positives than existing systems. Once it has been carefully and thoroughly tested, the device could be used to create a complete early-warning system for dangerous slopes. "Locations with a significant risk of landslides could definitely benefit from a machine like this," says Adam Poulter, an expert at the British Red Cross, "as long as it doesn"t cost too much." But, Poulter adds that an early-warning system may not be enough on its own. "You need to have the human communication," he says. "Making systems that get warnings to those who need them can be difficult."

单选题Job Woes, Health Blues? After Susan Joyce was laid off from Digital Equipment Corp. , she was horrified to hear of two suicides in her layoff group. Then she learned about a colleague who stabbed his wife to death and hung himself. "I worked with him for 10 years, maybe more," says Joyce. "He seemed like a nice guy. These cases may sound extreme, but being fired or laid off is undeniably one of life' s biggest blows and can lead to clinical depression, violence and alcohol abuse, as well as strokes and heart attacks. Even the fear of losing a job produces more doctor visits and health worries. In short, the recent news about rising unemployment and job insecurity may be bad news for our health. Layoffs create a sense of hopelessness. Stress - related complaints such as insomnia and headaches tend to follow, lingering even after victims find new jobs, says University of Michigan psychologist Richard Price, who tracked more than 700 layoff victims for two years. Research based on 17 years of Pennsylvania unemployment records concluded that employees affected by a mass layoff at a plant were 15 percent more likely to die of any cause over the next two decades. Experts blame the cascade (大量倾泻) of misfortune that often follows after a layoff, including the loss of health insurance. Your health can suffer simply from fear of losing your job, says Sarah Burgard, a sociologist at the University of Michigan. After crunching data from two large national surveys, she concluded that chronic job insecurity over a two - year period rivals the anxiety of a job loss or a major illness. Burgard adjusted her data for what psychologists call "neuroticism" and found that even people who aren' t typically worriers report worse health when they believe their jobs are in danger. Fears of poor job prospects may have similar consequences. When Swedish researchers asked 21 - year - olds about their health during a recession, they reported more problems than a comparison group during a boom. Economic stress may even show up in national public -health measures, although experts disagree about how to calculate those effects. Harvey Brenner, professor emeritus ([大学教师]退休后仍保留头衔的，荣誉退休的) at Johns Hopkins's Bloomberg School of Public Health and a professor of public health at the University of North Texas, argues that the 1 percentage point increase in unemployment since a year ago could have serious health repercussions (持续影响，反响) for the next two years. According to Brenner' s projections, there could be as many as 47,000 more deaths than would have otherwise occurred, including 1,200 more suicides, as well as nearly 26,000 more heart attacks. Should unemployment continue to rise, these numbers are likely to increase too, he says.
