单选题Since time immemorial, countless scholars have asked the question: What is beauty? As philosophers engage in weighty discourses, designers update the latest fashions, and artists create their masterpieces, what is considered beautiful changes at an alarming pace. Fifty years ago, the full-figured Marilyn Monroe embodied the American aesthetic value; today, a legion of Hollywood actresses vastly different in appearance from Marilyn"s have taken her place. However, aesthetic values not only differ from generation to generation, but do so along cultural lines as well. The conventions that govern painting and music vary greatly from East to West. Often, what is considered disgusting to one civilization is the pinnacle of aesthetic appeal in another. Thus, when left to the sphere of human design, the search for an absolute definition of beauty remains an elusive one at best. As fundamental physicists, my colleagues and I like to believe that we are involved in a search for a beauty that does not remain uninfluenced by definition; The beauty that we search for is not that which is laid down through the work of people and subject to short-term tastes, but rather that which has been established by Nature. Those not involved with physics tend to think of it as a precise and predictive science—certainly not a field of study fit for the contemplation of the beautiful. Yet, one of physics"s greatest gifts is that it allows its students to look past extrinsic appearances into a more overwhelming beauty. As a human being, I am captivated by the visual appeal of a wave crashing on the beach. As a physicist, however, I possess the ability to be captivated by the much deeper beauty of the physical laws that govern such a phenomenon. Where the nonphysicist sees a lovely but inexplicable event, the well-schooled physicist is able to perceive a brilliant design. In truth, since the day that Albert Einstein first proposed the notion that there might be one overarching physical theory that governs the universe, aesthetics has become a driving force in modern physics. What Einstein and we, as his intellectual descendants, have discovered is this;Nature, at its most fundamental level, is beautifully constructed. The remarkable simplicity of the laws that govern the universe is, at times, nothing short of breathtaking. And at every step, as new discoveries and technologies allow us to examine the physical world on deeper and deeper levels, we find that the beauty itself becomes more profound. As Einstein himself said, it would seem more likely that we should find ourselves living in a " chaotic world, in no way graspable through thinking. " Yet here we are, closer than ever to a full understanding of the universe"s beautiful clockwork.

单选题{{B}}Text 4{{/B}} In 1784, five years before he became president of the United States, George Washington, 52, was nearly toothless. So he hired a dentist to transplant nine teeth into his jaw—having extracted them from the mouths of his slaves. That's a far different image from the cherry-tree-chopping George most people remember from their history books. But recently, many historians have begun to focus on the roles slavery played in the lives of the founding generation. They have been spurred in part by DNA evidence made available in 1998, which almost certainly proved Thomas Jefferson had fathered at least one child with his slave Sally Hemings. And only over the past 30 years have scholars examined history from the bottom up. Works of several historians reveal the moral compromises made by the nation's early leaders and the fragile nature of the country's infancy. More significantly, they argue that many of the Founding Fathers knew slavery was wrong--and yet most did little to fight it. More than anything, the historians say, the founders were hampered by the culture of their time. While Washington and Jefferson privately expressed distaste for slavery, they also understood that it was part of the political and economic bedrock of the country they helped to create. For one thing, the South could not afford to part with its slaves. Owning slaves was "like having a large bank account," says Wiencek, author of An Imperfect God: George Washington, His Slaves, and the Creation of America. 'The southern states would not have signed the Constitution without protections for the "peculiar institution," including a clause that counted a slave as three fifths of a man for purposes of congressional representation. And the statesmen's political lives depended on slavery. The three-fifths formula handed Jefferson his narrow victory in the presidential election of 1800 by inflating the votes of the southern states in the Electoral College. Once in office, Jefferson extended slavery with the Louisiana Purchase in 1803; the new land was carved into 13 states, including three slave states. Still, Jefferson freed Hemings's children—though not Hemings herself or his approximately 150 other slaves. Washington, who had begun to believe that all men were created equal after observing the bravery of the black soldiers during the Revolutionary War, overcame the strong opposition of his relatives to grant his slaves their freedom in his will. Only a decade earlier, such an act would have required legislative approval in Virginia.

单选题There has been a lot of hand-wringing over the death of Elizabeth Steinberg. Without blaming anyone in particular, neighbors, friends, social workers, the police and newspaper editors have struggled to define the community"s responsibility to Elizabeth and to other battered children. As the collective soul-searching continues, there is a pervading sense that the system failed her. The fact is, in New York State the system couldn"t have saved her. It is almost impossible to protect a child from violent parents, especially if they are white, middle-class, well-educated and represented by counsel. Why does the state permit violence against children? There are a number of reasons. First, parental privilege is a rationalization. In the past, the law was giving its approval to the biblical injunction against sparing the rod. Second, while everyone agrees that the state must act to remove children from their homes when there is danger of serious physical or emotional harm, many child advocates believe that state intervention in the absence of serious injury is more harmful than helpful. Third, courts and legislatures tread carefully when their actions intrude or threaten to intrude on a relationship protected by the Constitution. In 1923, the Supreme Court recognized the "liberty of parent and guardian to direct the upbringing and education of children under their control." More recently, in 1977, it upheld the teacher"s privilege to use corporal punishment against schoolchildren. Read together, these decisions give the constitutional imprimatur to parental use of physical force. Under the best conditions, small children depend utterly on their parents for survival. Under the worst, their dependency dooms them. While it is questionable whether anyone or anything could have saved Elizabeth Steinberg, it is plain that the law provided no protection. To the contrary, by justifying the use of physical force against children as an acceptable method of education and control, the law lent a measure of plausibility and legitimacy to her parents" conduct. More than 80 years ago, in the teeth of parental resistance and Supreme Court doctrine, the New York State Legislature acted to eliminate child labor law. Now, the state must act to eliminate child abuse by banning corporal punishment. To break the cycle of violence, nothing less will answer. If there is a lesson to be drawn from the death of Elizabeth Steinberg, it is this: spare the rod and spare the child.

单选题The American Cancer Society, which has long been a staunch defender of most cancer screening, is now saying that the benefits of detecting many cancers, especially breast and prostate, have been overstated. It is quietly working on a message, to put on its Web site early next year, to emphasize that screening for breast and prostate cancers and certain other cancers can come with a real risk of over treating many small cancers while missing cancers that are deadly. The cancer society"s decision to reconsider its message about the risks as well as potential benefits of screening was spurred in part by an analysis published Wednesday in The Journal of the American Medical Association, Dr. Otis Brawley, chief medical officer of the cancer society, said. In it, researchers report a 40 percent increase in breast cancer diagnoses and a near doubling of early stage cancers, but just a 10 percent decline in cancers that have spread beyond the breast to the lymph nodes or elsewhere in the body. With prostate cancer, the situation is similar, the researchers report. If breast and prostate cancer screening really fulfilled their promise, the researchers note, cancers that once were found late, when they were often incurable, would now be found early, when they could be cured. A large increase in early cancers would be balanced by a corresponding decline in late-stage cancers. That is what happened with screening for colon and cervical cancers. But not with breast and prostate cancers. Still, the researchers and others say, they do not think all screening will—or should—go away. Instead, they say that when people make a decision about being screened, they should understand what is known about the risks and benefits. For now, those risks are not emphasized in the cancer society"s mammogram message which states that a mammogram is" one of the best things a woman can do to protect her health. " The new analysis finds that prostate cancer screening and breast cancer screening are not so different. Both have a problem that runs counter to everything people have been told about cancer; They are finding cancers that do not need to be found because they would never spread and kill or even be noticed if left alone. That has led to a huge increase in cancer diagnoses because, without screening, those innocuous cancers would go undetected. At the same time, both screening tests are not making much of a dent in the number of cancers that are deadly. That may be because many lethal breast cancers grow so fast they spring up between mammograms. And the deadly prostate ones have already spread at the time of cancer screening. The dilemma for breast and prostate screening is that it is not usually clear which tumors need aggressive treatment and which can be left alone. " The issue here is, as we look at cancer medicine over the last 35 or 40 years, we have always worked to treat cancer or to find cancer early, " Dr. Brawley said. " And we never sat back and actually thought. Are we treating the cancers that need to be treated?"
