单选题{{B}}Passage Two{{/B}} An investigation of the circulation of blood in the eyes of diver has produced the strongest evidence that tissue damage caused by diving is more common and more severe than had been previously thought. Of the 26 professional divers studied, all had abnormal retinas. None of the divers taking part in the study had visual problems as a result of their damaged retinas but Alan Bird of Moorfields Eye Hospital in London said that he "would not be surprised to find divers whose damage has progressed far enough to affect their vision". Evidence has mounted during recent years to show that exposure to pressure during diving subtly damages the central nervous system. Doctors believe that the damage is due to obstruction in the flow of blood through the tissues. People who take up diving as a sport know they are at risk of getting "the bends" or an air embolism, but if they follow the correct procedures, the risk is very low. All professional divers know they also run the risk of bone necrosis. About 5 per cent of them develop small dead patches in their bones. Active professional divers have their thighs and upper arms X-rayed as part of their annual medical examination. Doctors have been concerned diving-caused dead patches to appear on bones; other tissues may be suffering a similar fate. Their concern increased in the early 1950s. Detailed neurological examinations and tests of the memory and reactions of experienced professional divers suggested that some of them might have slight damage to the brain and spinal cord. In order to determine the size of the problem, the researchers needed a method of looking for the damage in a large sample of divers that did not involve surgery. The damage which occurs in the tissue of both the bones and the nerves of divers is similar. Damages of the retina which doctors can see using the technique are known as retinal angiography. The process involves injecting fluorocein dye into the blood stream and photographing the back of the eye through the pupil. The technique can provide a detailed photograph of the two vascular systems supplying blood to their retina without causing too much discomfort to the patient. The researchers suggested three mechanisms to explain how diving causes this obstruction. When divers come back to the surface, air bubbles sometimes form in their lungs. Bubbles forming in the lungs trigger changes in the body's clotting mechanism which could result in minute clots. The researchers hope that clues to the cause of the obstruction will come from investigations into the individual differences between divers. Some of the divers studied had relatively little damage even though they had been diving for many years and done a great deal of deep diving. On the other hand, a few inexperienced divers had quite extensive damage.

单选题 Justice in society must include both a fair trial to the accused and the selection of an appropriate punishment for those proven guilty. Because justice is regarded as one form of equality, we find in its earlier expressions the idea of a punishment equal to the crime. Recorded in the Old Testament is the expression "an eye for an eye, and a tooth for a tooth." That is, the individual who has done wrong has committed an offence against society. To make up for his offence, society must get even. This can be done only by doing an equal injury to him. This conception of retributive justice is reflected in many parts of the legal documents and procedures of modern times. It is illustrated when we demand the death penalty for a person who has committed murder. This philosophy of punishment was supported by the German idealist Hegel. He believed that society owed it to the criminal to give a punishment equal to the crime he had committed. The criminal had by his own actions denied his true self and it is necessary to do something that will counteract this denial and restore the self that has been denied. To the murderer nothing less than giving up his own will pay his debt. The demand of the death penalty is a right the state owes the criminal and it should not deny him his due. Modern jurists have tried to replace retributive justice with the notion of corrective justice. The aim of the latter is not to abandon the concept of equality but to find a more adequate way to express it. It tries to preserve the idea of equal opportunity for each individual to realize the best that is in him. The criminal is regarded as being socially ill and in need of treatment that will enable him to become a normal member of society. Before a treatment can be administered, the cause of his antisocial behavior must be found. If the cause can be removed, provisions must be made to have this done. Only those criminals who are incurable should be permanently separated front the rest of the society. This does not mean that criminals will escape punishment or be quickly returned to take up careers of crime. It means that justice is to heal the individual, not simply to get even with him. If severe punishments is the only adequate means for accompanying this, it should be administered. However, the individual should be given every opportunity to assume a normal place in society. His conviction of crime must not deprive him of the opportunity to make his way in the society of which he is a part.

单选题In the summer of 999, Leif Erikson voyaged to Norway and spent the following winter with King Olaf Tryggvason. Substantially the same account is given by both the Saga of Eric the Red and the Flat Island Book. The latter says nothing about Leif's return voyage to Greenland, but according to the former it was during this return voyage that Leif discovered America. The Flat Island Book, however, tells of another and earlier landfall by Biarni, the son of a prominent man named Heriulf, and makes that the inspiration for the voyage to the new land by Leif. In brief, like Leif, Biarni and his companion sight three countries in succession before reaching Greenland, and to come upon each new land takes 1 "doegr" more than the last until Biarni comes to land directly in front of his father's house in the last- mentioned country. This narrative has been rejected by most later writers, and they may be justified. Possibly, Biarni was a companion of Leif when he voyaged from Norway to Greenland via America, or it may he that the entire tale is But a garbled account of that voyage and Biarni another name for Leif. It should be noted, however, that the stories of Leif's visit to King Olaf and Biarni's to that king's predecessor are in the same narrative in the Flat Island Book, so there is less likelihood of duplication than if they were from different sources. Also, Biarni landed on none of the lands he passed, but Leif apparently landed on one, for he brought back specimens of wheat, vines, and timber. Nor is there any good reason to believe that the first land visited by Biarni was Wineland. The first land was "level and covered with woods", and "there were small hillocks upon it'. Of forests, later writers do not emphasize them particularly in connection with Wineland, though they are often noted incidentally. And of hills, the Saga says of Wineland only that "wherever there was hilly ground, there were vines". Additionally, if the two narratives were taken from the same source we should expect a closer resemblance of Helluland. The Saga says of it: "They found there hellus (large flat stones)." According to the Biarni narrative, however, "this land was high and mountainous." The intervals of 1, 2, 3, and 4 "doegr" in both narratives are suggestive, but mythic formulas of this kind may be introduced into narratives without altogether destroying their historicity. It is also held against the Biarni narrative that its hero is made to come upon the coast of Greenland exactly in front of his father's home. But it should be recalled that Heriufsness lay below two high mountains which served as landmarks for navigators. I would give up Biarni more readily were it not that the story of Leif's voyage contained in the supposedly more reliable Saga is almost as amazing. But Leif's voyage across the entire width of the North Atlantic is said to be "probable" because it is incorporated into the narrative of a preferred authority, while Biarni's is "improbable" or even "impossible" because the document containing it has been condemned.

单选题Thailand confirmed three new human bird flu cases Thursday as health officials warned it could take two years to conquer Asia's outbreak. Meanwhile, the World Health Organization said the latest tests show no sign of a killer hybrid virus that could easily pass between people. Tests on a cluster of bird flu cases in a Vietnamese family showed there was no mixing of genes between the bird flu strain and human flu, according to WHO. In the United States, a strain of bird flu was found at four live chicken markets in northern New Jersey, just days after outbreaks at two farms in Delaware led to the destruction of thousands of birds. WHO has said the best way to control the spread of the disease is by culling the birds. In Asia, tens of millions of chickens have been killed by infections or slaughtered in containment efforts as bird flu spread, jumping to people in Vietnam and Thai-land. The human death toll stood at 19 on Thursday. While two of the three people labeled as new cases in Thailand have recovered, the third, a 13-year-old boy, was in intensive care in northeastern Chaiyaphum province, Thai officials said. Fears of an outbreak prompted Singapore, believed free of bird flu, to announce plans to euthanize 5,000 healthy chickens in a drill to prepare for any possible infection. Ten governments in the region have dealt with the disease over the past couple of months, with China boosting its culling efforts as reports of infections there increased. Beijing said Thursday it was mobilizing 16,000 workers for anti-bird flu efforts in a province bordering Vietnam where China's first bird flu case of the season was confirmed in late January. Among their tasks is to try to pinpoint the source of the first infection. Destroying infected fowl is the best way to contain the outbreak, according to WHO. Thai officials have said slaughters of more than 26 million chickens have brought the disease largely under control there, while Vietnam has said its outbreak is easing. In Pakistan, U. N. officials said the disease has been contained. But the U. N. Food and Agriculture Organization said it would take much longer to bring the region's outbreak under control. "I would have thought that we'd be looking at a period of six months...but it could be as long as two years," FAO animal health officer Peter Roeder said in Geneva. In New Jersey, state veterinarian Nancy Halpern said the markets likely got the virus from one of their many farms and distributors. New Jersey has about 35 live chicken markets.

单选题In the decades between 1910 and 1930, over ten percent of the Black population of the United States left the South, where the majority of the Black population had been located, and migrated to northern states, with the largest number moving, it is claimed, between 1916 and 1918. It has been frequently assumed, but not proved, that most of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of cotton industry following boll-weevil infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the first World War in 1914. This assumption has led to the conclusion that the migrant"s subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills. But the question of who actually left the South has never been investigated in detail. Although numerous investigations document a flight from rural southern areas to southern cities prior to the Great Migration, no one has considered whether the same migrants then moved on to northern cities. In 1910 over 600,000 Black workers, or ten percent of the Black work force reported themselves to be engaged in "manufacturing and mechanical pursuits", the federal census category roughly including the entire industrial sector. The Great Migration could easily have been made up entirely of this group and their families. It is perhaps surprising to argue that an employed population could be tempted to move, but an explanation lies in the labor conditions then prevalent in the South. About thirty-five percent of the urban Black population in the South was engaged in skilled trades. Some were from the old artisan class of slavery—blacksmiths, masons, carpenters—which had a monopoly of certain trades, but they were gradually being pushed out by competition, mechanization, and obsolescence. The remaining sixty-five percent, more recently urbanized, worked in newly developed industries—tobacco, lumber, coal and iron manufacture, and railroads. Wages in the South, however, were low, and Black workers were aware, through labor recruiters and the Black press, that they could earn more even as unskilled workers in the North than they could as artisans in the South. After the boll-weevil infestation, urban Black workers faced competition from the continuing influx of both Black and White rural workers, who were driven to undercut the wages formerly paid for industrial jobs. Thus, a move north would be seen as advantageous to a group that was already urbanized and steadily employed, and the easy conclusion tying their subsequent economic problems in the North to their rural backgrounds comes into question.
