单选题We are told that the mass media are the greatest organs for enlightenment that the world has yet seen; that in Britain, for instance, several million people see each issue of the current affairs program. Panorama. It is true that never in human history were so many people so often and so much exposed to many intimations about societies, forms of life, attitudes other than those which they obtain in their local societies. This kind of exposure may well be a point of departure for acquiring certain important intellectual and imaginative qualities; width of judgment, a sense of the variety of possible attitudes. Yet in itself such exposure does not bring intellectual or imaginative development. It is no more than the masses of stone which lie around in quarry (采石场) and which may, conceivably, go to the making of a cathedral. The mass media cannot build the cathedral, and their way of showing the stone does not always prompt others to build. For the stones are presented within a self-contained and self-sufficient world in which, it is implied, simply to look at them, to observe fleetingly individually interesting points of difference between them, is sufficient in itself. Life is indeed full of problems on which we have to—or feel we should try to—make decisions, as citizens or as private individuals. But neither the real difficulty of these decisions, nor their true and disturbing challenge to each individual, can often be communicated through the mass media. The disinclination to suggest real choice, individual decision, which is to be found in the mass media, is not simply the product of a commercial desire to keep the customers happy. It is within the grain of mass communication. The organs of establishment, however well-intentioned they may be and whatever their form (the State, the Church, voluntary societies, political parties), have a vested interest (既得利益) in ensuring that the public boat is not violently rocked; and will so affect those who work within the mass media that they will be led insensibly towards forms of production which, though they go through the motions of dispute and inquiry, do not break through the skin to where such inquiries might really hurt. They will tend to move, when exposing problems, well within the accepted cliche assumptions of democratic society and will tend neither radically to question these cliches nor to make a disturbing application of them to features of contemporary life. They will stress the "stimulation" the programs give, but this soon becomes an agitation of problems for the sake of the interest of that agitation in itself; they will therefore, again, assist a form of acceptance of the status quo. There are except, ions to this tendency, but they are uncharacteristic.

单选题Campaigning on the Indian frontier is an experience by itself. Neither the landscape nor the people find their counterparts in any other portion of the globe. Valley wails rise steeply five or six thousand feet on every side. The columns crawl through a maze of giant corridors clown which fierce snow-fed torrents foam under skies of brass. Amid these scenes of savage brilliancy there dwells a race whose qualities seem to harmonize with their environment. Except at harvest time, when self-preservation requires a temporary truce, the Pathan tribes are always engaged in private or public war. Every man is a warrior, a politician and a theologian. Every large house is a real feudal fortress made, it is true, only of sun-baked clay, but with battlements, turrets, loopholes, drawbridges, etc. Every village has its defence. Every family cultivates its vendetta; every clan, its feud. The numerous tribes and combinations of tribes all have their accounts to settle with one another. Nothing is ever forgotten, and very few debts are left unpaid. For the purposes of social life, in addition to the convention about harvest-time, a most elaborate code of honour has been established and is on the whole faithfully observed. A man who knew it and observed it faultlessly might pass unarmed from one end of the frontier to another. The slightest technical slip would, however, be fatal. The life of the Pathan is thus full of interest; and his valleys, nourished alike by endless sunshine and abundant water, are fertile enough to yield with little labour the modest material requirements of a sparse population. Into this happy world the nineteenth century brought two new facts: the rifle and the British Government. The first was an enormous luxury and blessing; the second, an unmitigated nuisance. The convenience of the rifle was nowhere more appreciated than in the Indian highlands. A weapon which would kill with accuracy at fifteen hundred yards opened a whole new vista of delights to every family or clan which could acquire it. One could actually remain in one's own house and fire at one's neighbour nearly a mile away. One could lie in wait on some high crag, and at hitherto unheard of ranges hit a horseman far below. Even villages could fire at each other without the trouble of going far from home. Fabulous prices were therefore offered for these glorious products of science. Riflethieves scoured all India to reinforce the efforts of the honest smuggler. A steady flow of the coveted weapons spread its genial influence throughout the frontier, and the respect which the Pathan tribesmen entertained for Christian civilization was vastly enhanced. The action of the British Government on the other hand was entirely unsatisfactory. The great organizing, advancing, absorbing power to the southward seemed to be little better than a monstrous spoil-sport. If the Pathan made forays into the plains, not only were they driven back (which after all was no more than fair), but a whole series of subsequent interferences took place, followed at intervals by expeditions which toiled laboriously through the valleys, scolding the tribesmen and exacting fines for any damage which they had done. No one would have minded these expeditions if they had simply come, had a fight and then gone away again. In many cases this was their practice under what was called the "butcher and bolt policy" to which the Government of India long adhered. But towards the end of the nineteenth century these intruders began to make roads through many of the valleys, and in particular the great road to Chitral. They sought to ensure the safety of these roads by threats, by forts and by subsidies. There was no objection to the last method so far as it went. But the whole of this tendency to road-making was regarded by the Pathans with profound distaste. All along the road people were expected to keep quiet, not to shoot one another, and above all not to shoot at travellers along the road. It was too much to ask, and a whole series of quarrels took their origin from this source.

单选题Free Advice Is Just around the Corner When Daniel Franklin, a political science professor from Atlanta, needed career advancement advice, he didn't turn to colleagues, therapists or even his morn. He went to the Advice Ladies. Three thirty something New York women, advertising ffeelancers by day, have turned themselves into Saturday afternoon street-corner oracles, they pull up lawn chairs and a table on a lower Manhattan street corner and dish out free advice to passersby. They've claimed the corner of West Broadway and Broome Street in Soho as their own for the last several months. Amy Alkon, who, with longtime friends Marlowe Minnick and Carolyn Johnson, bebomes a part-time shrink each weekend. "We use creative problem-solving to turn problem into fun", she says. On a recent steamy afternoon, a line has formed in front of the Advice Ladies' table.Obviously, New Yorkers need plenty of help. "People feel they have no control in this crazy world. And therapy can take years," Minnick says. "We solve problems instantly, it's instant answer gratification." The three brainstorm before delivering advice on everything from pet discipline, closet-space management, even hair care. But no legal advice. "By far, most of our questions are love-related. It's amazing the intimate sexual problems that people will divulge to a total stranger," Alkon says. But they won't be strangers much longer. The Advice Ladies are putting together a book deal. And Robert De Nitro is creating a talk show around them, due nationally this fall from his Tribeca Pictures. "De Nitro asked us for advice, but we think he's already perfect," purrs Alkon. And their career advice to Franklin? "He's written a book, so we told him to get a manager and go on the touring circuit. It's great money and great publicity for the book. " "Good advice", says Franklin.

单选题The next time the men were taken up onto the deck, Kunta made a point of looking at the man behind him in line, the one who lay beside him to the left when they were below. He was a Serere tribesman much older than Kunta, and his body, front and back, was creased with whip cuts, some of them so deep and festering that Kunta felt badly for having wished sometimes that he might strike the man in the darkness for moaning so steadily in his pain. Staring back at Kunta, the Serere's dark eyes were full of fury and defiance. A whip lashed out even as they stood looking at each other-this time at Kunta, spurring him to move ahead. Trying to roll away, Kunta was kicked heavily in bis ribs. But somehow he and the gasping Wolof managed to stagger back up among the other men from their shelf who were shambling toward their dousing with buckets of seawater. A moment later, the stinging saltiness of it was burning in Kunta's wounds, and his screams joined those of others over the sound of the drum and the wheezing thing that had again begun marking time for the chained men to jump and dance for the toubob. Kunta and the Wolof were so weak from their new beating that twice they stumbled, but whip blows and kicks sent them hopping clumsily up and down in their chains. So great was his fury that Kunta was barely aware of the women singing "Toubob fa!" And when he had finally been chained back down in his place in the dark hold, his heart throbbed with a lust to murder toubob. Every few days the eight naked toubob would again come into the stinking darkness and scrape their tubs full of the excrement that had accumulated on the shelves where the chained men lay. Kunta would lie still with his eyes staring bale fully in hatred, following the bobbing orange lights, listening to the toubob cursing and sometimes slipping and t. ailing into the slickness underfoot-so plentiful now, because of the increasing looseness of the men's bowels, that the filth had begun to drop off the edges of the shelves down into the aisleway. The last time they were on deck, Kunta had noticed a man limping on a badly infected leg. This time the man was kept up on deck when the rest were taken back below. A few days later, the women told the other prisoners in their singing that the man's leg had been cut off and that one of the women had been brought to tend him, but that the man had died that night and been thrown over the side. Starting then, when the toubob came to clean the shelves, they also dropped red-hot pieces of metal into pails of strong vinegar. The clouds of acrid steam left the hold smelling better, but soon it would again be overwhelmed by the choking stink. It was a smell that Kunta felt would never leave his lungs and skin. The steady murmuring that went on in the hold whenever the toubob were gone kept growing in volume and intensity as the men began to communicate better and better with one another. Words not understood were .whispered from mouth to ear along the shelves until someone who knew more than one tongue would send back their meanings. In the process, all of the men along each shelf learned new words in tongues they had not spoken before. Sometimes men jerked upward, bumping their heads, in the double excitement of communicating with each other and the fact that it was being done without the toubob's knowledge. Muttering among themselves for hours, the men developed a deepening sense of intrigue and of brotherhood. Though they were of different villages and tribes, the feeling grew that they were not from different peoples or places.

单选题Modern technology may not have improved the world all that much but it certainly has made life noisier. Unmuffled motorcycles, blaring car alarms, and roving boom boxes come first, second, and third on my list of most obnoxious noise offenders, but everyone could come up with his own version of aural hell—if he could just find a quiet spot to ponder the matter. Yet what technology has done, other technology is now starting to undo, using computer power, to zap those ear-splitting noises into silence. Previously silence-seekers had little recourse except to stay inside, close the windows, and plug their ears. Remedies like these are quaintly termed "passive" systems, because they place physical barriers against the unwanted sound. Now computer technology is producing a far more effective "active" system, which doesn't just contain, deflect, or mask the noise, but annihilates it electronically. The system works by countering the offending noise with "anti-noise", a somewhat sinister-sounding term that calls to mind antimatter, black holes, and other Popular Science mindbenders but that actually refers to something quite simple. Just as a wave on a pond is flattened when it merges with a trough that is its exact opposite (or mirror image) , so can a sound wave be negated by meeting its opposite. This general theory of sound cancellation has been around since the 1930s. In the fifties and sixties it made for a kind of magic trick among laboratory acousticians playing around with the first clunky mainframe computers. The advent of low-cost high-power microprocessors has made active noise-cancellation systems a commercial possibility, and a handful of small electronics firms in the United States and abroad are bringing the first ones onto the silence market. Silence buffs might be hoping that the noise-canceling apparatus will take the shape of the 44 Magnum wielded by Dirty Harry, but in fact active sound control is not quite that active. The system might more properly be described as reactive, in that it responds to sound waves already headed toward human ears. In the configuration that is usual for such systems microphones detect the noise signal and send it to the system's microprocessor, which almost instantly models it and creates its inverse for loudspeakers to fire at the original. Because the two sounds occupy the same range of frequencies and tones, the inverse sounds exactly like the noise it is to eliminate: the anti-noise cancelling Beethoven's Fifth Symphony is heard as Beethoven's Fifth. The only difference is that every positive pressure produced on the air by the orchestra is matched by a negative pressure produced by the computer, and every negative pressure is matched by a positive, thereby silencing the sound. The system is most effective as a kind of muffler, in which microphones, microprocessor, and loudspeaker are all in a unit encasing the device that produces the sound, stifling it at its source. But it can work as a headset, too, negating the sound at the last moment before it disturbs one's peace of mind.
