单选题According to a survey, which was based on the responses of over 188, 000 students, today's traditional- age college freshmen are "more materialistic and less altruistic (利他主义的) "than at any time in the 17 years of the poll. Not surprising in these hard times, the student's major objective "is to be financially well off. Less important than ever is developing a meaningful philosophy of life. It follows then that today the most popular course is not literature or history but accounting". Interest in teaching, social service and the "altruistic" fields is at a low. on the other hand, enrollment in business programs, engineering and computer science is way up. That's no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors her first year on the job--even before she completed her two-year associate degree. While it's true that we all need a career, it is equally tame that our civilization has accumulated an incredible amount of knowledge in fields far removed flora our own and that we are better for ear understanding of these other contributions--be they scientific or artistic. It is equally true that, in studying the diverse wisdom of others, we learn how to think. More important, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs. Weekly we mad of unions who went on strike for higher wages, only to drive their employer out of business. No company; no job. How shortsighted in the long run ! But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机): "Miss Baxter," he says, "could you please send in someone who can distinguish fight from wrong?" From the long-term point of view, that's what education really ought to be about.

单选题 The marvelous telephone and television network that has now enmeshed the whole world, making all men neighbors, cannot be extended into space. It will never be possible to converse with anyone on another planet. Even with today's radio equipment, the messages will take minutes--sometimes hours--on their journey, because radio and light waves travel at the same limited speed of 186, 000 miles a second. Twenty years from now you will be able to listen to a friend on Mars, but the words you hear will have left his mouth at least three minutes earlier, and your reply will take a corresponding time to reach him. In such circumstances, an exchange of verbal messages is possible--but not a conversation. To a culture which has come to take instantaneous communication for granted, as part of the very structure of civilized life, this "time barrier" may have a profound psychological impact. It will be a perpetual reminder of universal laws and limitations against which not all our technology can ever prevail. For it seems as certain as anything can be that no signal--still less any material object--can ever travel faster than light. The velocity of light is the ultimate speed limit, being part of the very structure of space and time. Within the narrow confines of the solar system, it will not handicap us too severely. At the worst, these will amount to twenty hours--the time it takes a radio signal to span the orbit of Pluto, the outer most planet. It is when we move out beyond the confines of the solar system that we come face to face with an altogether new group of cosmic reality. Even today, many otherwise educated men--like those savages who can count to three but lump together all numbers beyond four--cannot grasp the profound distinction between solar and stellar space. The first is the space enclosing our neighboring worlds, the planets, the second is that which embraces those distant suns, the stars, and it is literally millions of times greater. There is not such abrupt change of scale in the terrestrial affairs. Many conservative scientists, shocked by these cosmic gulfs, have denied that they can ever be crossed. Some people never learn, those who sixty years ago laughed at the possibility of flight, and ten years ago laughed at the idea of travel to the planets, are now quite sure that the stars will always be beyond our reach. And again they are wrong, for they have failed to grasp the great lesson of our age--that if something is possible in theory, and no fundamental scientific laws oppose its realization, then sooner or later it will be achieved. One day we shall discover a really efficient means of propelling our space vehicles. Every technical device is always developed to its limit and the ultimate speed for spaceships is the velocity of light. They will never reach that goal, but they will get very near it. And then the nearest star will be less than five years of voyaging from the earth.

单选题Many economists believed that ______ consumers would cut spending once the value of their homes began to fall.

单选题The growth of cell-phone users in the U.S. has tapered off from the breakneck pace of 50% annually in the late 1990s to what analysts project will be a 15% to 20% rise in 2002, and no more than that in 2003. To some extent, numerous surveys have found, slower growth in demand reflects consumer disillusionment with just about every aspect of cell-phone service—its reliability, quality, and notorious customer service. The cooling off in demand threatens to cascade through the industry: The big four U.S. cell-phone carders—Verizon Wireless, Cingular Wireless, AT&T Wireless, Sprint imperil their timetables for becoming profitable, not to mention their efforts to whittle down their mountains of debt. As the carders have begun to cut costs, wireless- equipment makers—companies such as Lucent, Nokia, and Ericsson—have been left with a market that"s bound to be smaller than they had anticipated. Handset makers have been insulated so far, but they, too, face a nagging uncertainty. They"ll soon introduce advanced phones to the U.S. market that will run on the new networks the carders are starting up over the next year or two. But the question then will be: Will Americans embrace these snazzy data features—and their higher costs—with the wild enthusiasm that Europeans and Asians have? Long before the outcome in clear, the industry will have to adopt a new mind-set. "In the old days, it was all about connectivity." says Andrew Cole, an analyst with wireless consultancy Adventis. Build the network, and customers will come. From now on, the stakes will be higher. The new mantra: Please customers, or you may not survive. To work their way out of this box, the carders are spending huge sums to address the problem. Much of Sprint PCS"s $ 3.4 billion in capital outlays this year will be for new stations. And in fact, the new high-speed, high-capacity nationwide networks due to roll out later this year should help ease the calling-capacity crunch that has caused many consumer complaints. In the meantime, some companies are using better training and organization to keep customers happy. The nation"s largest rural operator, Alltel (AT), recently reorganized its call centers so that a customer"s query goes to the first operator who"s available anywhere in the country, instead of the first one available in the customer"s home area. That should cut waiting time to one minute from three to five minutes previously.

单选题{{B}}Passage Five{{/B}} Can the Internet help patients jump the line at the doctor's office? The Silicon Valley Employers Forum, a sophisticated group of technology companies, is launching a pilot program to test online "virtual visits" between doctors at three big local medical groups and about 6, 000 employees and their families. The six employers taking part in the Silicon Valley initiative, including heavy hitters such as Oracle and Cisco Systems, hope that online visits will mean employees won't have to skip work to tend to minor ailments or to follow up on chronic conditions. "With our long commutes and traffic, driving 40 miles to your doctor in your hometown can be a big chunk of time," says Cindy Conway, benefits director at Cadence Design Systems, one of the participating companies. Doctors aren't clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stifling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work." In the pilot program, physicians will get $ 20 per online consultation, about what they get for a simple office visit. Doctors also fear they'll be swamped by rambling E-mails that tell everything but what's needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif.-based start-up. Healinx's "Smart Symptom Wizard" questions patients and turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face-to-face visit. Can E-mail replace the doctor's office? Many conditions, such as persistent cough, require a stethoscope to discover what's wrong and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor's groups in the pilot, believes the virtual doctor's visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet's record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healinx," notes Michael Barrett, an analyst at Internet consulting firm Forester Research. If the "Web visits" succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren't satisfied, figure on one more E-health start-up to stand down.

单选题Every dream is a message from your unconscious self, expressed in a code which only you can understand and interpret. The images, colors, moods and terms of your dreams depend upon your culture, upbringing, slang and your own understanding of things and values. Dreaming is like looking into a mirror and seeing yourself with your own eyes. The first dreams which we have after falling asleep often revolve around the day's events. We go through them, sorting out and discarding things we don't need to remember and gaining insight into those we do. Often, we are inspired with suggestions that we can use to remedy the situations that plague us by day. As we progress through the night's dreams, they may take up more fantastic qualities, offering fanciful experiences. These often pleasant images can relieve the stress of the day. But the dream we have just before the awakening often contains information the subconscious mind wants to make known to the conscious. And this information, if remembered, interpreted, and understood, can serve as an important tool in our lives. Depending upon the content, dream can strike us with their peculiarity, or sometimes even their alarming nature. Some dreams haunt us for years, not only because of their persistence, but also primarily because we cannot explain or understand them. Other dreams stand out with the weird mixture of images, emotions and context, which make us remember them for life. Recurring dreams are quite common, and we usually have them when a certain life situation repeats, or we are facing the same problem over and over again. A recurring dream is often a sign of some emotional weakness in our nature which causes us problems over the years. Lucid dreams are rare, but they are all about people's ability to control their dreams. In such a dream, the dreamer becomes consciously aware that she/he is dreaming and is able to use the memory and participate in dream actions and emotions. Lucid dreams are usually enhanced in a sensory and imaginary way, and sometimes can be accompanied by pleasant music. People can learn the techniques of controlling their dreams. Some historic manuscripts and records say that the ability to control dreams helps a person to reach a higher degree of mind development. This is what some Tibetan Buddhists and Islam followers practiced for the purpose of elevation in consciousness.

单选题It"s becoming something of a joke along the Maine-Canada border. So many busloads of retired people crisscross the line looking for affordable drugs that the roadside stands should advertise, "Lobsters. Blueberries. Lipitor. Coumalin." Except, of course, that such a market in prescription drugs would be illegal. These senior long-distance shopping sprees fall in a legal gray zone. But as long as people cross the border with prescriptions from a physician and have them filled for no more than a three-month supply for personal use, customs and other federal officials leave them alone. The trip might be tiring, but people can save an average of 60 percent on the cost of their prescription drugs. For some, that"s the difference between taking the drugs or doing without. "The last bus trip I was on six months ago had 25 seniors," says Chellie Pingree, former Maine state senator and now president of Common Cause. "Those 25 people saved $19,000 on their supplies of drugs." Pingree sponsored Maine RX, which authorizes a discounted price on drugs for Maine residents who lack insurance coverage. The law was challenged by drug companies but recently upheld by the U.S. Supreme Court. It hasn"t yet taken effect. Figuring out ways to spend less on prescription drugs has become a multifaceted national movement of consumers, largely senior citizens. The prescription drug bill in America is $160 billion annually, and people over 65 fill five times as many prescriptions as working Americans on average. "But they do it on health benefits that are half as good and on incomes that are half as large," says Richard Evans, senior analyst at Sanford C. Bernstein, an investment research firm. What"s more, seniors account for 20 percent of the voting public. It"s little wonder that the May 19 Supreme Court ruling got the attention of drug manufacturers and politicians across the country. The often-over-looked state of 1.3 million tucked in the northeast corner of the country became David to the pharmaceutical industry"s Goliath. The face-off began three years ago when state legislators like Pingree began questioning why Maine"s elderly population had to take all those bus trips.
