单选题 The simple act of surrendering a telephone number to a store clerk may seem innocuous—so much so that many consumers do it with no questions asked. Yet that one action can set in motion a cascade of silent events, as that data point is acquired, analyzed, categorized, stored and sold over and over again. Future attacks on your privacy may come from anywhere, from anyone with money to purchase that phone number you surrendered. If you doubt the multiplier effect, consider your e-mail inbox. If it's loaded with spam, it's undoubtedly because at some point in time you unknowingly surrendered your e-mail to the wrong Web site. Do you think your telephone number or address are handled differently? A cottage industry of small companies with names you've probably never heard of—like Acxiom or Merlin—buy and sell your personal information the way other commodities like corn or cattle futures are bartered. You may think your cell phone is unlisted, but if you've ever ordered a pizza, it might not be. Merlin is one of many commercial data brokers that advertises sale of unlisted phone numbers compiled from various sources—including pizza delivery companies. These unintended, unpredictable consequences that flow from simple actions make privacy issues difficult to grasp, and grapple with. In a larger sense, privacy also is often cast as a tale of "Big Brother"—the government is watching you or a big corporation is watching you. But privacy issues don't necessarily involve large faceless institutions: A spouse takes a casual glance at her husband's Blackberry, a co-worker looks at e-mail over your shoulder or a friend glances at a cell phone text message from the next seat on the bus. While very little of this is news to anyone—people are now well aware there are video cameras and Internet cookies everywhere—there is abundant evidence that people live their lives ignorant of the monitoring, assuming a mythical level of privacy. People write e-mails and type instant messages they never expect anyone to see. Just ask Mark Foley or even Bill Gates, whose e-mails were a cornerstone of the Justice Department's antitrust case against Microsoft. And polls and studies have repeatedly shown that Americans are indifferent to privacy concerns. The general defense for such indifference is summed up a single phrase: "I have nothing to hide. " If you have nothing to hide, why shouldn't the government be able to peek at your phone records, your wife see your e-mail or a company send you junk mail? It's a powerful argument, one that privacy advocates spend considerable time discussing and strategizing over. It is hard to deny, however, that people behave different when they're being watched. And it is also impossible to deny that Americans are now being watched more than at any time in history.

单选题On September 7, 2001, a 68-year-old woman in Strasbourg, France, had her gall bladder (胆囊) removed by-surgeons operating, via computer from New York. It was the first complete telesurgery procedure performed by surgeons nearly 4 000 miles away from their patient. In New York, Marescaux teamed up with surgeon Michel Gagner to perform the historic long-distance operation. A high-speed fiber-optic service provided by France Telecom made the connection between New York and Strasbourg. The two surgeons controlled the instruments using an advanced robotic surgical system, designed by Computer Motion Inc. that enabled the procedure to be minimally invasive. The patient was released from the hospital after about 48 hours and regained normal activity the following week. The high-speed fiber-optic connection between New York and France made it possible to overcome a key obstacle to telesurgery time delay. It was crucial that a continuous time delay of less than 200 milliseconds be maintained throughout the operation, between the surgeon' s movements in New York and the return video (from Strasbourg) on his screen. The delay problem includes video coding decoding and signal transmission time. France Telecom' s engineers achieved an average time delay of 150 milliseconds. " I felt as comfortable operating on my patient as if I had been in the room," says Marescaux. The successful collaboration (合作) among medicine, advanced technology, and telecomm unications is likely to have enormous implications for patient care and doctor training. Highly skilled surgeons may soon regularly perform especially difficult operations through long-distance procedures. The computer systems used to control surgical movement can also lead to a breakthrough in teaching surgical techniques to a new generation of physicians. More surgeons-in-training will have the opportunity to observe their teachers in action in telesurgery operating rooms around the world. Marescaux describes the success of the remotely performed surgical procedure as the beginning of a "third revolution" in surgery within the last decade. The first was the arrival of minimally invasive surgery, enabling procedures to be performed with guidance by a camera, meaning that the abdomen (腹部) and thorax (胸腔) do not have to be opened. The second was the introduction of computer-assisted surgery, where complicated software algorithms(计算法)enhance the safety of the surgeon's movements during a procedure, making them more accurate, while introducing the concept of distance between the surgeon and the patient. It was thus natural to imagine that this distance-currently several meters in the operating room could potentially be up to several thousand kilometers.

单选题Children were expected to be {{U}}obedient{{/U}} and contribute to the well-being of the family.

单选题The target is multifaceted: the country hopes to gain military strength and be unafraid of foreign threats, while creating a high standard of living.

单选题When foreigners are sometimes asked what seems most strange about American society, somewhere on the top of the list will be the fact that the average citizen is allowed to possess guns. Although it is true that many people carry guns legally in the United States, it is also known that many who possess guns carry them illegally. Others, who don't have guns, feel that guns can be acquired quite easily. A recent survey indicated that many high school students, especially in the inner cities, can acquire a gun with little difficulty. Although most people would never want to own a gun, others have taken up hunting as a sport and enjoy hunting wild game in season. Hunting for deer and duck in fall and winter is very much a part of the American culture. Also, some farmers in rural areas who raise cattle and sheep feel they need to protect their animals against wolves that attack their herds and flocks at night. To defend and support their rights to possess firearms the National Rifle Association (NRA) was founded in 1871. The main importance of this organization has been its efforts to prevent strict gun control legislation. The NRA has great political support in small towns and rural areas, especially in the West and the South, where hunting is especially popular. Those who favor the right to possess guns insist that the Constitution provides the right of people "to keep and bear arms." They believe that gun con- trol laws will not solve the problem of crime and violence in America. Recent events in America, however, have shown that the question of gun possession is now out of control and strong voices have called for immediate action to be taken. In seemingly peaceful schools students have gone into classrooms and opened fire upon their classmates. America has been shocked by such incidents which seem to occur with greater frequency. The periodic deaths of innocent citizens and even foreign visitors from guns have forced legislators to pass laws to stop these senseless killings. The day may not be far off when America will be transformed from a gun culture to one which controls their use and possession.

单选题Introspection is kind of a drag. It requires unpleasant acts like "thinking" and "talking about emotions," and it can rarely be done while watching TV. But like it or not, more and more workers are taking time to reflect on what they do for a living, seeking jobs that aren"t just a means to a paycheck but the fulfilment of some form of calling. Can this supposedly enlightening feeling that your career is "a calling" be a bad thing? Teresa Cardador, an assistant professor in the school of labor and employment relations at the University of Illinois recently co-authored a paper in the Journal of Career Assessment that reviewed research on people who find meaning and a sense of purpose in their work. "There has become this idealized notion of work," Cardador said. "A lot of books and stories in the popular press capture this idea of an idealized orientation toward work. But there"s increasing evidence that suggests that despite the perceived desirability, it"s not always beneficial." In a nutshell, what Cardador found is that people who view their work as a calling can get too wrapped up in the job, to the point where it becomes counterproductive. Some people burn out—it"s called "the fall from the call." Sometimes the person with the calling believes he or she is the only one qualified to handle the work, and that can cause strained relationships with co-workers. Also, the intense focus on work can be depleting, leaving a worker without enough energy to maintain good relationships outside the office. However, "callings can be healthy when individuals inspire and connect with others at work," Cardador said. Between constantly evolving technology and downsizing that requires more of individual workers, it"s critical that a worker accept the fact that her or his job tasks may not always be the same. We have to be flexible nowadays, even if certain tasks don"t fit our idealized vision of the job. The study said. "People with rigid work identities have a single way of viewing who they are and what they do at work and are unwilling or unable to bend this image to fit with the reality of their work situation. In so doing, they are less able to account for the needs and interests of others in the workplace." Just because you feel passionate about what you do doesn"t mean you can"t do other things that contribute to the greater good of your organization. You have to step back and examine how you"re handling your work, making sure, in the simplest of terms, that you"re not unwittingly being a selfish jerk. After all, we work, predominantly, because there are no money trees to harvest. The hope is that our labor lets us build the lives we want. If that comes with a feeling of fulfillment, fantastic.
