单选题Passage One Before the conference began, a Japanese businessman was introduced to an American businessman at the lounge. The Japanese businessman, arms extending downwards from his shoulders, bowed from his waist toward the American businessman to whom he was just introduced. His eyes were directed ahead, his face showed no particular expression. The American businessman stood straight. His eyes focused on the Japanese man's eyes. He smiled and put out his right hand. Both men smiled briefly in embarrassment. The Japanese man straightened up and put out his right hand. The American withdrew his hand and bowed his head. A broader smile of embarrassment, and some noise from each man—not really words, just some sounds from their throats—indicating discomfort. They were in the course of a conflict of customs; they had different habits for greeting people they were being introduced to. When people are planning to go to another country, they expect to encounter certain kinds of differences. They usually expect the weather and the food to be different. They expect to find differences in some of the material aspects of life, such as the availability of cars, electricity, and home heating systems. And, without knowing the details, they expect differences in customs. Customs are the behaviors that are generally expected in specific situations. American men, for example, shake hands with each other when first introduced while Japanese men bow.

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 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.
