单选题 The Tuscan town of Vinci, birthplace of Leonardo and home to a museum of his machines, should fittingly put on a show of the television-robot sculptures of Nam Jun Paik. This Korean-born American artist and the Renaissance master are kindred spirits: Leonardo saw humanistic potential in his scientific experiments, Mr. Paik endeavors to harness media technology for artistic purposes. A pioneer of video art in the late 1960s, he treats television as a space for art images and as material for robots and interactive sculptures. Mr. Paik was not alone. He and fellow artists picked on the video cameras because they offered an easy way to record their performance art. Now, to mark video art's coming of age, New York's Museum of Modern Art is looking back at their efforts in a film series called "The First Decade". It celebrates the early days of video by screening the archives of Electronic Arts Intermix (EAI), one of the world's leading distributors of video and new media art, founded 30 years ago. One of EAI's most famous alumni is Bill Viola. Part of the second generation of video artists, who emerged in the 1970s, Mr. Viola experimented with video's expressive potential His camera explores religious ritual and universal ideas. The Viola show at the Deutsche Guggenheim in Berlin shows us moving-image frescoes that cover the gallery walls and envelop the viewer in all-embracing cycles of life and death. One new star is a Californian, Doug Aitken, who took over London's Serpentine Gallery last October with an installation called "New Ocean". Some say Mr. Aitken is to video what Jackson Pollock was to painting. He drips his images from floor to ceiling, creating sequences of rooms in which the space surrounds the viewer in hallucinatory images, of sound and light. At the Serpentine, Mr. Aitken created a collage of moving images, on the theme of water's flow around the planet as a force of life. "I wanted to create a new topography in this work, a liquid image, to show a world that never stands still," he says. The boundary between the physical world and the world of images and information, he thinks, is blurring. The interplay of illusion and reality, sound and image, references to art history, politics, film and television in this art form that is barely 30 years old can make video art difficult to define. Many call it film-based or moving-image art to include artists who work with other cinematic media. At its best, the appeal of video art lies in its versatility, its power to capture the passing of time and on its ability to communicate both inside and outside gallery walls.

单选题On an average of six times a day, a doctor in Holland practices “active” euthanasia (安乐死):intentionally administering a lethal (致死的)drug to a terminally iii patient who has asked to be relieved of suffering. Twenty times a day, life-prolonging treatment is withheld or withdrawn when there is no hope that it can effect an ultimate cure. "Active" euthanasia remains a crime on the Dutch statute books, punishable by 12 years in prison. But a series of court cases over the past 15 years has made it clear that a competent physician who carries it out will not be prosecuted. Euthanasia, often called "mercy killing" is a crime everywhere in Western Europe. But more and more doctors and nurses readily admit to practicing it, most often in the "passive" form of withholding or withdrawing treatment. The long simmering euthanasia issue has lately boiled over into a, sometimes, fierce public debate, with both sides claiming the mantle of ultimate righteousness. Those opposed to the practice see themselves upholding sacred principles of respect for life, while those in favor raise the banner of humane treatment. After years on the defensive, the advocates now seem to be gaining ground. Recent polls in Britain show that 72 percent of British subjects favor euthanasia ill some circumstances. An astonishing 76 percent of respondents to a poll taken last year in France said they would like the law changed to decriminalize mercy killings. Euthanasia has been a topic of controversy in Europe since at least 1936, when a bill was introduced in the House of Lords that would have legalized mercy killing under very tightly supervised conditions. That bill failed, as have three others introduced in the House of Lords since then. Reasons for the latest surge of interest in euthanasia are not hard to find. Europeans, like Americans, are now living longer: Therefore, lingering chronic diseases have replaced critical illnesses as the primary cause of death. And the euthanasists argue that every human being should have the right to "die with dignity," by which they usually mean the right to escape the horrors of a painful or degrading hospitalization (住院治疗). Most experts believe that euthanasia will continue to be practiced no matter what the law says.

单选题{{B}}Text 2{{/B}} In the next century we'll be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. When Dr. Frankenstein made his monster, he wrestled with the moral issue of whether he should allow it to reproduce, "Had I the right, for my own benefit, to inflict the curse upon everlasting generations?" Will such questions require us to develop new moral philosophies? Probably not. Instead, we'll reach again for a time-tested moral concept; one sometimes called the Golden Rule and which Kant, the millennium's most prudent moralist, conjured up into a categorical imperative, Do unto others as you would have them do unto you; treat each person as an individual rather than as a means to some end. Under this moral precept we should recoil at human cloning, because it inevitably entails using humans as means to other humans' ends and valuing them as copies of others we loved or as collections of body parts, not as individuals in their own right. We should also draw a line, however fuzzy, that would permit using genetic engineering to cure diseases and disabilities but not to change the personal attributes that make someone an individual (IQ, physical appearance, gender and sexuality). The biotech age will also give us more reason to guard our personal privacy. Aldous Huxley in Brave New World, got it wrong: rather than centralizing power in the hands of the state, DNA technology has empowered individuals and families. But the state will have an important role, making sure that no one, including insurance companies, can look at our genetic data without our permission or use it to discriminate against us. Then we can get ready for the breakthroughs that could come at the end of the next century and the technology is comparable to mapping our genes: plotting the 10 billion or more neurons of our brain. With that information we might someday be able to create artificial intelligences that think and experience consciousness in ways that are indistinguishable from a human brain. Eventually we might be able to replicate our own minds in a "dry-ware" machine, so that we could live on without the "wet-ware" of a biological brain and body. The 20th century's revolution in infotechnology will thereby merge with the 21st century's revolution in biotechnology. But this is science fiction. Let's turn the page now and get back to real science.

单选题 It is said that in England death is pressing, in Canada inevitable and in California optional Small wonder. Americans' life expectancy has nearly doubled over the past century. Failing hips can be replaced, clinical depression controlled, cataracts removed in a 30-minutes surgical procedure. Such advances offer the aging population a quality of life that was unimaginable when I entered medicine 50 years ago. But not even a great health-care system can cure death—and our failure to confront that reality now threatens this greatness of ours. Death is normal; we are genetically programmed to disintegrate and perish, even under ideal conditions. We all understand that at some level, yet as medical consumers we treat death as a problem to be solved. Shielded by third-party payers from the cost of our care, we demand everything that can possibly be done for us, even if it's useless. The most obvious example is late-stage cancer care. Physicians-frustrated by their inability to cure the disease and fearing loss of hope in the patient—too often offer aggressive treatment far beyond what is scientifically justified. In 1950, the U.S. spent $12.7 billion on health care. In 2002, the cost will be $1540 billion. Anyone can see this trend is unsustainable. Yet few seem willing to try to reverse it. Some scholars conclude that a government with finite resources should simply stop paying for medical care that sustains life beyond a certain age—say 83 or so. Former Colorado governor Richard Lamm has been quoted as saying that the old and infirm "have a duty todie and get out of the way" , so that younger, healthier people can realize their potential. I would not go that far. Energetic people now routinely work through their 60s and beyond, and remain dazzlingly productive. At 78, Viacom chairman Sumner Redstone jokingly claims to be 53. Supreme Court Justice Sandra Day O'Connor is in her 70s, and former surgeon general C. Everett Koop chairs an Internet start-up in his 80s. These leaders are living proof that prevention works and that we can manage the health problems that come naturally with age. As a mere 68-year-old, I wish to age as productively as they have. Yet there are limits to what a society can spend in this pursuit. Ask a physician, I know the most costly and dramatic measures may be ineffective and painful. I also know that people in Japan and Sweden, countries that spend far less on medical care, have achieved longer, healthier lives than we have. As a nation, we may be overfunding the quest for unlikely cures while underfunding research on humbler therapies that could improve people's lives.

单选题For many people today, reading is no longer relaxation. To keep up with their work, they must read letters, reports, trade publications, interoffice communications, not to mention newspapers and magazines: a never-ending flood of words. In 1 a job or advancing in one, the ability to read and comprehend 2 can mean the difference between success and failure. Yet the unfortunate fact is that most of us are 3 readers. Most of us develop poor reading 4 at an early age, and never get over them. The main deficiency 5 in the actual stuff of language itself—words. Taken individually, words have 6 meaning until they are strung together into phrases, sentences and paragraphs. 7 , however, the untrained reader does not read groups of words. He laboriously reads one word at a time, often regressing to 8 words or passages. Regression, the tendency to look back over 9 you have just read, is a common bad habit in reading. Another habit which 10 down the speed of reading is vocalization (发声) —sounding each word either orally or mentally as 11 reads. To overcome these bad habits, some reading clinics use a device called an 12 , which moves a bar (or curtain) down the page at a predetermined speed. The bar is set at a slightly faster rate 13 the reader finds comfortable, in order to "stretch" him. The accelerator forces the reader to read fast, 14 word-by-word reading, regression and subvocalization practically impossible. At first 15 is sacrificed for speed. But when you learn to read ideas and concepts, you will not only read faster, 16 your comprehension will improve.
