1填空题The first two stages in the development of civilized man were probably the invention of primitive weapons and the discovery of fire, although nobody knows exactly when he acquired the use of the latter. 41) ______ Animals have a few cries that serve as signals, but even the highest apes have not been found able to pronounce words, even with the most intensive professional instruction. The superior brain of man is apparently a necessity for the mastering of speech. When man became sufficiently intelligent, we must suppose that he gradually increased the number of cries for different purposes. It was a great day when he discovered that speech could be used for narrative. There are those who think that in this respect picture language preceded oral language. A man could draw a picture on the wall of his cave to show in which direction he had gone, or what prey he hoped to catch. 42) ______ Two important stages came not so long before the dawn of written history. The first was the domestication of animals; the second was agriculture. Agriculture made possible an immense increase in the number of the human species in the regions where it could be successfully practiced. 43) ______ 44) ______ These inventions and discoveries--fire, speech, weapons domestic animals, agriculture, and writing--made the existence of civilized communities possible. From about 3000 B. C. until the beginning of the Industrial Revolution less than two hundred years ago there was no technical advance comparable to these. During this long period man had time to become accustomed to his technique, and to develop the beliefs and political organizations appropriate to it. There was, of course, an immense extension in the area of civilized life. At first it had been confined to the Nile, the Euphrates, the Tigris, and the Indus, but at the end of the period in question it covered much the greatest part of the inhabitable globe. I do not mean to suggest that there was no technical progress during the time. 45) ______ (512 words)Notes: ape 猿。pastoral nomad 田园式的游牧部落的人。the Euphrates 幼发拉底河。the Tigris底格里斯河。the Indus 印度河。in question 所谈的(在名词后作后置定语)。[A] Probably picture language and. oral language developed side by side. I am inclined to think that language has been the most important single factor in the development of man.[B] Another fundamental technical advance was writing, which, like spoken language, developed out of pictures, but as soon as it had reached a certain stage, it was possible to keep records and transmit information to people who were not present when the information was given.[C] With the development of civilization, primitive people who lived in caves at that time badly needed a language, which would help them to communicate with one another.[D] The origin of language is also obscure. No doubt it began very gradually.[E] In fact, there was progress--there were even two inventions of very great importance, namely, gunpowder and the mariner's compass--but neither of these can be compared in their revolutionary power to such things as speech and writing and agriculture.[F] These were, at first, only those in which nature fertilized the soil after each harvest. Agriculture met with violent resistance from the pastoral nomads, but the agricultural way of life prevailed in the end because of the physical comforts it provided.[G] But industry was a step in human progress to which subsequently there was nothing comparable until our own machine age.
2单选题These are hard times for Deutsehe Bank, despite its huge strides in investment banking. Next week its chief executive, Josef Ackerman, goes on trial in Dusseldorf. Careless words by Rolf Breuer, the head of its supervisory board, led to another court ruling last month that may cost Germany' s biggest bank several hundred million euros in damages. Then there is Parmalat. Although no evidence has emerged of complicity in the Italian dairy group' s fraud, Deutsche' s name has become entwined in the affair. In many other respects, however, Deutsche' s reputation has never been higher. In dubbing it " Bank of the Year 2003", International Financing Review, the capital markets' favorite newssheet, purred that Deutsche was a "lean, aggressive, focused universal bank" In the league tables that investment banks watch so keenly, Deutsche excelled last year as lead manager of bonds and convertible bonds and of some racier products, such as repackaged debt securities and high-yield "junk" bonds. In other disciplines it rarely fell below the top ten in the world. However, it is still nowhere near the top in equity offerings and advice on mergers and acquisitions, except in Germany. It still has a problem with costs,which were a fat 82% of income in the third quarter of 2003, thanks mainly to the thick pay packets of its investment bankers and its poor returns from corporate and retail banking. Mr. Ackermann must try to improve the weak spots while spending two clays a week, probably until June, in a courtroom. He and four others face charges of "breach of trust" over the way bonuses were awarded to board meinbers of Mannesmann, a telecoms company. Mr. Aekermann sat on Mannesmann' s supervisory board. There is no suggestion that he gained personally. Nor was there any harmful intent in Mr. Breuer' s remarks in a television interview about the financial health of the Kirch media group shortly before its bankruptcy. But he was careless, and a Munich court found Deutsche (but not Mr. Breuer) liable for damages, to be set in due course, without right of appeal. The bank said this week it has lodged a protest with the federal supreme court in Karlsruhe. Meanwhile, Kirch has filed a suit against Deutsche in America. Deutsche's involvement with Parmalat also looks sloppy. It led a 350m bond issue fur the group in September. It was also a leading borrower and lender of Parma[at shares, so that in November it technically held the voting rights to over 5% of Parmalat stock. That stake had fallen to 1.5% by December 19th, the day the dairy company's black hole became public. It reported this, perhaps over-zealously, to the Italian authorities. That may have given the wrong impression, say, sources close to the bank, because the transactions were for third parties. This is awkward for a bank that managed to avoid most serious attacks on conflicts of interest thai beset the investment-banking industry following the collapse of Enron in 2001 and the bursting of the tech-stock bubble. Mr. Ackermann will need a clear head to steer the bank through the coming storms.
3单选题Horse thieves, cattle rustlers, bank robbers, train and stagecoach robbers, highwaymen, murderers, these were but some of the criminals who infested the American frontier during the 19th century. In English legend Robin Hood can be considered a bandit, but the outlaws of the Old West were far more violent men and women without any scruples when it came to taking property or life. The careers of many outlaws have been glamorized through fictional accounts of their deeds and their exploits have been the basis for many movie scripts. The era of the American outlaw lasted about 100 years roughly from 1800 to 1900.There had been lawlessness during the Colonial Era. Frontiers have always attracted misfits, failures and renegades who hope to profit by being beyond the reach of government. In the years just before the Revolutionary War, gangs of horse thieves in the back country of South Carolina were broken up by organized bands of farmers called regulators. As frontier settlement expanded rapidly after the Revolution, more opportunities for criminals opened, two common types of bandits were highwaymen and river pirates. Highwaymen accosted people who traveled on foot or horseback, while river pirates preyed upon the boat traffic on the Ohio, Mississippi, and other rivers. Some bandits engaged in both. Criminals in the West gathered momentum with the gold rushes to California, Idaho, Montana, Nevada, and other states. Stagecoaches and trains carrying gold and money became prime targets for bands of outlaws. Bank robberies emerged after the California Gold Rush of 1849 and as prosperity found its way to frontier towns. The first stage robbery was recorded in 1851, and the first train robbery happened in 1866. After the Civil War there was the growth of the cattle kingdom in Texas and neighboring states. Cattle rustling and horse theft turned into significant operations. Range wars bred a great amount of violence. Cattlemen fought over land and water rights, and they fought with great bitterness against sheep farmers. In Texas, range wars were fought over the use of barbed wire to fence grazing land. By the end of the 19th century, the frontier era was past. Major crime shifted to the cities. Ethnic gangs had existed in the slums for decades, preying mostly on their fellow immigrants. With the arrival of Prohibition in the 1920s, an impetus was given to the formation of organized crime as it exists today.
4单选题That rapscallion who leaps off the monkey bars, landing smack onto an innocent 3-year-old bystander, and skips off, giggling all the while? According to a new paper out of Israel, he may not feel all that bad about the incident. The study, conducted by Dr. In bal Kivenson Bar-On at the University of Haifa, shows that high levels of fearlessness in 3-and 4-year-olds is strongly associated with aggression and a lack of sympathy. This news will likely surprise risk-loving America, where parents typically beam with pride when their undaunted child mounts the big slide. Fearlessness is a far-end point on the spectrum of what psychologists call the "approach and withdrawal dimension"—people's tendency to approach new stimuli (to gain information and acquire new skills ) and withdraw from unfamiliar stimuli (to avoid danger). Striking the right balance is considered crucial to man's survival. But what about preschoolers'? There's a clear downside, Dr. Kivenson Bar-On discovered, after she observed lots of preschool play and machinations. In total, she documented 80 children at preschool, home and in the lab, measuring their propensity for fearlessness and other social and emotional characteristics at the beginning and end of one year. Fearlessness was measured by observing reactions to various fright-inducing situations: separation from parents, the roar of a vacuum cleaner, a jack-in-the-box and the like. Those who displayed greater levels of fearlessness, the study found, had no trouble recognizing facial expressions of anger, surprise, happiness and sadness in other children—but they had a hard time identifying fear. Over all, they were "emotionally shallow" and showed lower levels of sympathy. They took advantage of friends and lacked regret over inappropriate conduct. "These findings," the paper explains, " suggest that fearlessness in preschool constitutes a clear risk factor for developmental pathways that lead to problems in morality, conscience development, and severe antisocial behaviors. " At the same time, fearless children tended to be highly sociable. "One of the most interesting findings was that we could discriminate between friendliness and sympathy," Dr. Kivenson Bar-On said. "These kids are curious, easygoing and friendly, but they have a hard time recognizing emotional distress in others. " Jamie Ostrov, a psychology professor at the State University at Buffalo who studies aggression, says that children at the extreme end of the fearless spectrurn "may be charming, but they're also highly manipulative and deceptive and skilled at getting their way—even at age 3 or 4. " It could be that fearless children need stronger distress cues to active their autonomic nervous systems, limiting their ability to detect distress cues in others. It seems to be, if I'm not worried about this, you can't be, either. But should we be?

6单选题The human Y chromosome—the DNA chunk that makes a man a man—has lost so many genes over evolutionary time that some scientists have suspected it might disappear in 10 million years. But a new study says it'll stick around. Researchers found no sign of gene loss over the past 6 million years, suggesting the chromosome is "doing a pretty good job of maintaining itself," said researcher David Page of the Whitehead Institute for Biomedical Research in Cambridge, Mass. That agrees with prior mathematical calculations that suggested the rate of gene loss would slow as the chromosome evolved, Page and study co-authors note in Thursday's issue of the journal Nature. And, they say, it clashes with what Page called the "imminent demise" idea that says the Y chromosome is doomed to extinction. The Y appeared 300 million years ago and has since eroded into a dinky chromosome, because it lacks the mechanism other chromosomes have to get rid of damaged DNA. So mutations have disabled hundreds of its original genes, causing them to be shed as useless. The Y now contains only 27 genes or families of virtually identical genes. In 2003, Page reported that the modern-day Y has an unusual mechanism to fix about half of its genes and protect them from disappearing. But he said some scientists disagreed with his conclusion. The new paper focuses on a region of the Y chromosome where genes can't be fixed that way. Researchers compared the human and chimpanzee versions of this region. Humans and chimps have been evolving separately for about 6 million years, so scientists reasoned that the comparisons would reveal genes that have become disabled in one species or the other during that time. They found five such genes on the chimp chromosome, but none on the human chromosome, an imbalance Page called surprising. "It looks like there has been little if any gene loss in our own species lineage in the last 6 million years," Page said. That contradicts the idea that the human Y chromosome has continued to lose genes so fast it'll disappear in 10 million years, he said. "I think we can with confidence dismiss … the 'imminent demise' theory," Page said. Jennifer A. Marshall Graves of the Australian National University in Canberra, a gene researcher who argues for eventual extinction of the Y chromosome, called Page's work "beautiful" but said it didn't shake her conviction that the Y is doomed. The only real question is when, not if, the Y chromosome disappears, she said. "It could be a lot shorter than 10 million years, but it could be a lot longer," she said. The Y chromosome has already disappeared in some other animals, and "there's no reason to expect it can't happen to humans," she said. If it happened in people, some other chromosome would probably take over the sex-determining role of the Y, she said.
7问答题(46) Many journalism critics have recently argued that American journalism is undergoing a profound change because it now regularly mixes entertainment with the news. Critics typically argue that this entertainment is in the form of sensationalistic celebrity-scandal. In fact, there is a long history of sensationalism in American journalism, a fact documented by several journalism historians. (47) But the main point of contemporary critics is that sensationalism and tabloid-style techniques, which were always present on the fringes of journalism, are now becoming the norm in American journalism, and are being adopted by so-called "mainstream" media as part of economic survival strategies in the cutthroat business climate of American mass media. These contemporary critics typically argue that there should be a rigid boundary between mainstream journalism and other kinds of mass communication such as tabloid journalism. (48) The critics imply that one kind of communication is more legitimate in certain contexts than the other, and even that tabloid journalism is not journalism at all but is instead entertainment. One of the claims made by mass media critics is that journalism just recently got worse. But this may be a perennial complaint. (49) A quick review of journalism criticism reveals that the argument that journalism used to be better but just recently got worse is common throughout the history of journalism. The critiques usually say that journalism used to make bold distinctions between news and entertainment but now combines the two. These critiques construct the logical conclusion that journalism has steadily declined in quality over many years. (50) Taken together, the criticisms add up to the conclusions that the people who used to do journalism were better and had higher standards than those of today and that the distinctions between news and entertainment used to be greater. Examples of this critique can be found in even the earliest discussions of American journalism. For instance, critics panned Benjamin Day's New York Sun of the early 1830s because it often contained humor and sensational news of suicides. Similarly, some critics hated James Gordon Bennett's New York Herald of the mid-to late-1830s because it contained entertaining satirically written police court reports, as well as in-depth crime stories. Bennett pioneered the "human-interest story" or feature story when he wrote in vivid detail in 1836 about the grisly murder of the prostitute Helen Jewett, quoting her madam and describing Jewett's apartment in minute detail. Bennett's day-by-day narrative of the ensuing sensational trial reminds us of how journalism and entertaining literature have been combined for many years to make newsworthy stories "more palatable for consumption. " Bennett was soundly criticized by his competitors and others for blurring the boundary between journalism and entertainment. His detractors, many of them his competitors, waged what they called a "Moral War" in the late 1830s against Bennett and his enjoyable but sensationalistic newspaper. They maintained that Bennett was a "deviant" journalist because he blurred the boundaries of journalism by making his newspaper entertaining and popular. Those running the "Moral War" against Bennett were unsuccessful at running him out of the journalism business, but they did seriously wound his business.
