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.

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. "

单选题The "MyDoom" virus could presage a generation of computer attacks by organised gangs aiming to extract ransoms from online businesses, experts said yesterday. The warning came as the website run by SCO, a company that sells Unix computer software, in effect disappeared from the web under a blizzard of automated attacks from PCs infected by the virus, which first appeared a week ago. The "MyDoom-A" version of the virus is reckoned to be the worst to have hit the internet, in terms of the speed of its spread, with millions of PCs worldwide believed to be infected. Such "zombie" machines begin to send out hundreds of copies of the virus every hour to almost any e-mail address in their files. On Sunday they began sending automated queries to SCO's website, an attack that will continue until 12 February. The attack is the web equivalent of ringing the company's doorbell and running away a million times a second, leaving its computers unable to deal with standard requests to view its pages. "You have to wonder about the time limit," said Graham Cluley, senior technology consultant at the antivirus company Sophos. "Someone could go to SCO after the 12th and say, 'If you don't want this to happen again, here are our demands'." Raimund Genes, European president of the security software firm Trend Micro, said: "Such a programme could take out any major website on the internet. It's not terrorism, but it is somebody who is obviously upset with SCO" SCO has earned the enmity of computer users through a lawsuit it has filed against IBM. SCO claims ownership of computer code it says IBM put into the free operating system Linux, and is demanding licence fees and damages of $1bn. Mr. Cluley said: "It might be that whoever is behind this will say to SCO, 'if you don't want the next one to target you, drop the lawsuit'." SCO has offered $250,000 (￡140,000) for information leading to the arrest of the person or people who wrote and distributed MyDoom. Nell Barrett, of the security company Information Risk Management, said, "I would give a lot of credence to the idea of gangs using viruses to extort money. It's hard for law enforcement to track them down, because they're using machines owned by innocent people." A second variant of MyDoom will start attacking part of Microsoft's website later today. The antivirus company MessageLabs said it had blocked more than 16 million copies of the virus in transit over the net so far. But millions more will have reached their targets.

单选题Called by many critics the greatest achievement of English lyrical poetry, this elegy was written upon the death of a fellow alumnus of Milton's, Edward King, who was drowned in the Irish Sea in 1637. A group of King's former schoolmates at Cambridge issued a commemorative volume titled Obsequies to the Memory of Mr. Edward King (1638). It was in this limited publication that Lycidas first appeared. Heretofore, of his great poems only Comus had been published, and that anonymously. Lycidas is not an expression of personal grief ( personal grief was to be eloquent in Milton's next important poem, the Latin Epitaphium Damonis), but rather a record of the thoughts that King's death evoked in the poet. King had written verses himself and had prepared himself for the Church. These two facts of the dead man's career form the basis for what Milton had to say. Outwardly the poem is written in the tradition of pastoral poetry, and more particularly in the tradition of the pastoral elegy as exhibited in the ancient Greek Lament for Bion by Moschus. The poet is spoken of as a shepherd. But Milton introduces the innovation of identifying the Christian idea of shepherd (pastor) as meaning priest. In a wonderful fusion of pagan and Christian tradition, Milton makes his elegy the occasion for a scathing attack on the corruptions of the clergy in his time, with parenthetical thrusts of scorn at his trivial contemporaries, the Cavalier poets. Samuel Johnson, who disliked all pastoral poetry, made the one outstandingly foolish judgment of his career, in dismissing Lycidas as a work of an. He said its "diction is harsh, the rhymes uncertain, and the numbers unpleasing, "--a testimony of the fact that Johnson was deaf to the refinements of English poetry at its subtlest, for Lycidas is an exquisite piece of music from the first line through the last. Moreover, Johnson was upset at the mingling of "trifling fictions" with "the most awful and sacred truths, such as ought never to be polluted with such irreverent combinations." That pronouncement can only mean that Johnson failed to grasp the noble idea at the center of the poem: Milton's definition of the high function of a poet.
