单选题Next week, the European Parliament will debate stringent regulation of a number of effective pesticides. If this regulation is passed, the consequences will be devastating. In the 1960s, widespread use of the potent and safe insecticide DDT led to eradication of many insect-borne diseases in Europe and North America. But based on no scientific evidence of human health effects, the U. S. Environmental Protection Agency banned DDT, and its European counterparts followed suit. Subsequently, more than 1 million people died each year from malaria—but not in America or Europe. Rather, most of the victims were children and women in Africa and Asia. Today, even while acknowledging that indoor spraying of small amounts of DDT would help prevent many deaths and millions of illnesses, nongovernmental organizations continue—with great success—to pressure African governments not to allow its use. In order to stave off such pressure, African public health officials cave, and their children die needlessly. Yet, rather than learning the tragic lesson of the DDT ban, the European Union wants to extend this unscientific ban to other effective insecticides, including pyrethroids and organophosphates—further undercutting anti-malarial efforts. The currently debated regulation would engender a paradigm shift in the regulation of chemicals, from a risk-based approach—based on real world exposures from agricultural applications—to a hazard-based standard, derived from laboratory tests and having little or no basis in reality as far as human health is concerned. Of course, this is fine with anti-chemical zealots. Their concern is bringing down chemical companies in the name of "the environment" —tough luck if African children have to be sacrificed to their agenda, as was the case with DDT(which is still banned in the EU and not under consideration in the current debate). Most poignantly, the fight against malaria and other insect-borne tropical diseases would take another hit, with resulting illness, disability and death disproportionally affecting children under five and pregnant women. And what, after all, is the "danger" of these chemicals being debated? In fact, there is no evidence to support the contention that insecticides pose a health threat to humans. Even DDT, one of the most studied chemicals of all time, has been conclusively shown to be safe for humans at all conceivable levels of exposure sufficient to control malaria and save millions of lives.

单选题The question of whether war is inevitable is one which has concerned many of the world"s great writers. Before considering this question, it will be useful to introduce some related concepts. Conflict, defined as opposition among social entities directed against one another, is distinguished from competition, defined as opposition among social entities independently striving for something which is in inadequate supply. Competitors may not be aware of one another, while the parties to a conflict are. Conflict and competition are both categories of opposition, which has been defined as a process by which social entities function in the disservice of one another. Opposition is thus contrasted with cooperation, the process by which social entities function in the service of one another. These definitions are necessary because it is important to emphasize that competition between individuals or groups is inevitable in a world of limited resources, but conflict is not. Conflict, nevertheless, is very likely to occur, and is probably an essential and desirable element of human societies. Many authors have argued for the inevitability of war from the premise that in the struggle for existence among animal species, only the fittest survive. In general, however, this struggle in nature is competition, not conflict. Social animals, such as monkeys and cattle, fight to win or maintain leadership of the group. The struggle for existence occurs not in such fights, but in the competition for limited feeding areas and for occupancy of areas free from meat-eating animals. Those who fail in this competition starve to death or become victims to other species. This struggle for existence does not resemble human war, but rather the competition of individuals for jobs, markets, and materials. The essence of the struggle is the competition for the necessities of life that are insufficient to satisfy all. Among nations there is competition in developing resources, trades, skills, and a satisfactory way of life. The successful nations grow and prosper; the unsuccessful decline. While it is true that this competition may induce efforts to expand territory at the expense of others, and thus lead to conflict, it cannot be said that war-like conflict among nations is inevitable, although competition is.

单选题As soon as it was revealed that a reporter for progressive magazine had discovered bow to make a hydrogen bomb, a group of firearm(火器) fans formed the National Hydrogen Bomb Association, and they are now lobbying against any legislation to stop Americans from owning one. "The Constitution," said the associationes spokesman, "gives everyone the right to own arms. It doesn't spell out what kind of arms. But since anyone can now make a hydmgen bomb, the public should be able to buy it to protect theraselves." "Don't you think it's dangerous to have one in the house, particularly where there are children around?" "The National Hydrogen Bomb Association hopes to educate people in the safe handling of this type of weapon. We are instrueting owners to keep the bomb in a locked cabinet and the fuse(导火索) separately in a drawer." "Some people consider the hydrogen bomb a very fatal weapon which could kill somebody." The spokesman said, "Hydrogen bombs don't kill people--people kill people. The bomb is for selfpro-tection and it also has a deterrent effect. If somebody knows you have a nuelear weapon in your house, they're going to think twice about breaking in." "But those who want to ban the bomb for American citizens claim that if you have one locked in the cabinet, with the fuse in a drawer, you would never be able to assemble it in time to stop an intruder(侵入者)." "Another argument against allowing people to own a bomb is that at the moment it is very expensive to build one So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns./

单选题{{B}}Passage Four{{/B}} An Ohio State University study has linked behavior in young children with the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people tended to have offspring with relatively low levels of behavior problems. The opposite held true when the jobs were routine, closely supervised, and dealt with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has positive consequences for her children's behavior," indicates associate professor of sociology Elizabeth Menaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book-keeping, food service, and assembly line positions. Women who are supervised closely at work and made to follow strict orders may be more likely to use this same style in raising their kids. They may emphasize obedience to parental authority and the potential for physical punishment. "We believe that the choice of such a parenting style may increase the frequency of behavior problems in children." On the other hand, mothers whose jobs are less controlled by supervisors and who must work closely with other people probably rely less on physical punishment, instead encouraging children to think about consequences of their actions and take responsibility for their behavior. Such an approach encourages youngsters to follow parental demands even when they aren't being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don't involve constant supervision "develop problem-solving skills that they can bring to other parts of their life". The research also found that those who have more challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, in turn, is linked to fewer behavior problems.

单选题People who begin to go deaf in adult life have different problems from those who are born deaf. They have to learn different ways of behaving and different ways of communication—perhaps at a time when learning is not all that easy. A heating aid is not a complete solution to the problem. The sound perceived by the deaf person through a hearing aid is distorted and appears to have more background noise than is heard by someone with normal hearing. Deafened people have to lip-read as well. Lipreading is difficult, demands intense concentration, and an uninterrupted direct view of the speaker's face. No other activities can take place at the same time: the lipreadar has to stop eating, stop everything in order to concentrate on hearing. It is not a question of stupidity or bad temper—as it sometimes appears to be—but a question of being very easy to misunderstand when tile sound is distorted. Remember what it's like trying to communicate on a very bad telephone line. Frustrating, isn't it? The deaf have to face that all the time. A useful way of looking at the problem is to see the deaf person as a foreigner—to treat them as if you were in a foreign country. You would speak more clearly, slowly and raise your voice slightly. And you'd use gestures to make your meaning clear, as well as have no hesitation in using pencil and paper to be absolutely certain. You can de all those things with the deaf—as well as making sure you don't obscure your mouth with your hand, a pipe or a cigarette. Another point quite often overlooked is that a hearing aid may be quite efficient and useful in a quiet, carpeted room—but try it in the street during rush hour, in a noisy ear, in a railway station ticket office, a cinema or a concert hall and you've got a really difficult problem to distinguish speech. So don't suggest to or encourage deaf people to go to functions which are going to make their disability appear worse—and increase their sense of failure. Careful selection of cinemas with good sound systems is important and you should experiment to find out where the best seats are for hearing. Fitting adaptors for radio and television, observing which 15lends are easier to understand, and making sure that people talking are well-lit are all useful and positive activities.

单选题The history of responds to the work of the artist Sandro Botticelli (1444-1510) suggests that widespread appreciation by critics is a relatively recent phenomenon. Writing in 1550, Vasari expressed an unease with Botticelli"s work, admitting that the artist fitted awkwardly into his evolutionary scheme of the history of art. Over the next two centuries, academic art historians defamed Botticelli in favor of his fellows Florentine, Michelangelo. Even when anti-academic art historians of the early nineteenth century rejected many of the standards of evaluation adopted by their predecessors, Botticelli"s work remained outside of accepted taste, pleasing neither amateur observers nor connoisseurs. (Many of his best paintings, however, remained hidden away in obscure churches and private homes.) The primary reason for Botticelli"s unpopularity is not difficult to understand: most observers, up until the mid-nineteenth century, did not consider him to be noteworthy, because his work, for the most part, did not seem to these observers to exhibit the traditional characteristics of fifteenth-century Florentine art. For example, Botticelli rarely employed the technique of strict perspective and, unlike Michelangelo, never used chiaroscuro. Another reason for Botticelli"s unpopularity may have been that his attitude toward the style of classical art was very different from that of his contemporaries. Although he was thoroughly exposed to classical art, he showed little interest in borrowing from the classical style. Indeed, it is paradoxical that a painter of large-scale classical subjects adopted a style that was only slightly similar to that of classical art. In any case, when viewers began to examine more closely the relationship of Botticelli"s work to the tradition of fifteenth-century Florentine art, his reputation began to grow. Analyses and assessments of Botticelli made between 1850 and 1870 by the artists of the Pre-Raphaelite movement, as well as by the writer Pater (although he, unfortunately, based his assessment on an incorrect analysis of Botticelli"s personality), inspired a new appreciation of Botticelli throughout the English-speaking world. Yet Botticelli"s work, especially the Sistine frescoes, did not generate worldwide attention until it was finally subjected to a comprehensive and scrupulous analysis by Home in 1908. Home rightly demonstrated that the frescoes shared important features with paintings by other fifteenth-century Florentines—features such as skillful representation of anatomical proportions, and of the human figure in motion. However, Home argued that Botticelli did not treat these qualities as ends in themselves—rather, that he emphasized clear depletion of a story, a unique achievement and one that made the traditional Florentine qualities less central. Because of Home"s emphasis crucial to any study of art, the twentieth century has come to appreciate Botticelli"s achievements.

单选题Most American magazines and newspapers reserve 60 percent of their pages for ads. The New York Times Sunday edition 1 may contain 350 pages of advertisements. Some radio stations devote 40 minutes of every hour to 2 . Then there is television. According to one estimate, American youngsters sit 3 three hours of television commercials each week. By the time they graduate from high school, they will have been 4 360,000 TV ads. Televisions advertise in airports, hospital waiting rooms, and schools. Major sporting 5 are now major advertising events. Racing cars serve as high speed 6 Some athletes receive most of their money from advertisers. One 7 basketball player earned $ 3.9 million by playing ball. Advertisers paid him nine times that much to 8 their products. There is no escape.

They decorate the inside of taxis and subways—even the doors of public toilets. 9 messages call to us in supermarkets, stores, elevators—and 10 we. are on hold on the telephone. In some countries so much advertising comes through the mail that many recipients proceed directly from the mailbox to the nearest wastebasket to 11 the junk mail. 12 Insider"s Report, published by McCann-Erickson, a global advertising agency, the estimated 13 of money spent on advertising worldwide in 1990 was $275.5 billion. Since then, the figures have 14 to $ 411.6 billion for 1997 and a projected $434.4 billion for 1998. Big money ! What is the effect of all of this? One analyst 15 it this way: "Advertising is one of the most powerful socializing forces in the culture. Ads sell more than products. They sell images, values, goals, concepts of who we are and who we should be. They shape our attitudes and our attitudes shape our behavior. "
