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.
Dr. Frankenstein's remarks are mentioned in the text
A．to give an episode of the DNA technological breakthroughs.
B．to highlight the inevitability of a means to some evil ends.
C．to show how he created a new form. of life a thousand years ago.
D．to introduce the topic of moral philosophies concerning biotechnology.
(27) When the Europeans came to the New World, the Indians, at first, taught the settlers how to plant corn, bake fish, make canoes and smoke tobacco. In return, the whites introduced horses, guns, gun-powder and alcohol. But at last, there were struggles for land, and the struggles could have only one result-war. When the wars were over, all Indians were moved to large tracts of land called reservations. Now, some of them, embittered by past mistreatment, are determined to preserve their tribal life; some wish to modernize the reservations. These alternatives, with many variations, are what most Indians have chosen-a future in modern technology and education, or the revival of ancient tradition and treaties.
The Indians entered North America______.
A．with Columbus
B．before Columbus did
C．after Columbus' arrival
D．in the 18th century
A poignant is the dilemma that parents find themselves in today as a consequence of successive radical changes in the image of the child in society and in our theories of childrearing.
At the turn of the century in the United States, for example, the dominant theory reflected the prevailing scientific belief in the importance of heredity in determining behavior. Mothers who had never heard of Darwin or Spencer raised their babies in ways consistent with the world views of these thinkers. Vulgarized and simplified, passed from person to person, these world views were reflected in the conviction of millions of ordinary people that "bad children are a result of bad stock", that "crime is hereditary", etc.
In the early decades of the century, these attitudes fell back before the advance of environmentalism. The belief that environment shapes personality, and that the early years are the most important, created a new image of the child. The work of Watson and Pavlov began to creep into the public ken. Mothers reflected the new behaviorism, refusing to feed infants on demand, refusing to pick them up when they cried, weaning early to avoid prolonged dependency.
A study by Martha Wolfenstein has compared the advice offered parents in seven successive editions of INFANT CARE, a handbook issued by the United Stats Children's Bureau between 1914 and 1951. She found distinct shifts in the preferred methods for dealing with weaning and thumb-sucking. It is clear from this study that by the late thirties still another image of the child had gained ascendancy. Freudian concepts swept in like a wave and revolutionized childrearing practices. Suddenly, mothers began to hear about "the rights of infants" and the need for "oral gratification". Permissiveness became the order of the day.
The passage tells us that any new knowledge will have a powerful influence on ordinary people if ______.
A．it is simple and understandable
B．it is advocated by eminent persons
C．it has been put into practice and prove tree
D．it bas something to do with their immediate concerns

Iron was rapidly adopted for the construction of bridges, because its strength was far greater than that of stone or timber, but its use in the architecture of buildings developed more slowly, By 1800 a complete internal iron skeleton for buildings bad been developed in industrial architecture replacing traditional timber beams, but it generally remained concealed. Apart from its low cost, the appeal of iron as a building material lay in its strength, its resistance to fire, and its potential to span vast areas. As a result, iron became increasingly popular as a structural material for more traditional styles of architecture during the nineteenth century, but it was invariably concealed.
Significantly, the use of exposed iron occurred mainly in the new building types produced by the Industrial Revolution: in factories, warehouses, commercial offices, exhibition halls, and railroad stations, where its practical advantages far outweighed its lack of status. Designers of the railroad stations of the new age explored the potential of iron, covering huge areas with spans that surpassed the great vaults of medieval churches and cathedrals. Paxton's Crystal Palace, designed to house the Great Exhibition of 1851, covered an area of 1848 feet by 408 feet in assembled units of glass set in iron frames. The Paris Exhibition of 1889 included both the widest span and the greatest height achieved so far with the Halle des Machines, spanning 362 feet, and the Eiffel Tower 1,000 feet high. However, these achievements were mocked by the artists of Paris as expensive and ugly foolishness. Iron, despite its structural advantages, had little aesthetic(审美的) status, The use of an exposed iron structure in the more traditional styles of architecture was slower to develop.
What does the passage mainly discuss？
A．Advances in iron processing in the eighteenth and nineteenth centuries.
B．The effects of the Industrial Revolution on traditional architectural styles.
C．Advantages of stone and timber over steel as building materials.
D．The evolution of the use of iron in architecture.
In agriculture, the transformation was marked by the emergence of the grain elevators, the cotton presses, the warehouses, and the commodity exchanges that seemed to so many of the nation's farmers the visible sign of a vast conspiracy against them. In manufacturing, the transformation was marked by the emergence of a "new factory system" in which plants became larger, more complex, and more systematically organized and managed. And in distribution, the transformation was marked by the emergence of the jobber(中间商), the wholesaler, and 'the mass retailer(零售商). These changes radically altered the nature of work during the half century between 1870 and 1920.
To be sure, there were still small workshops, where skilled craftspeople manufactured products ranging from newspapers to cabinets to plumbing fixtures. There were the sweatshops in city tenements, where groups of men and women in household settings manufactured clothing or cigars on a piecework basis. And there were factories in occupations such as metalwork where individual contractors presided over what were essentially handicraft proprietorships that coexisted within a single building. But as the number of wage earners in manufacturing rose from 2.7 million in 1888 to 4.5 million in 1900 to 8.4 million in 1920, the number of huge plants like the Baldwin Locomotive Works in Philadelphia burgeoned (迅速成长), as did the size of average plant. (The Baldwin Works had 600 employees in 1855, 3,000 in 1875, and 8,000 in 1900.) By 1920, at least in the northeastern United States where most of the nation's manufacturing wage earners were concentrated, three-quarters of those worked in factories with more than 100 employees and 30 percent worked in factories with more than 100 employees.
What can be inferred from the passage about the agricultural sector of the economy after the Civil War？______
A．New technological developments had little effect on farmers
B．The percentage of the total population working in agriculture declined
C．Many farms destroyed in the war were rebuilt after the war
D．Farmers achieved new, prosperity because of better rural transportation
