单选题{{B}}第三篇{{/B}} Egypt Felled by Famine Even ancient Egypts mighty pyramid builders were powerless in the face of the famine that helped bring down their civilian around 2180 BC. Now evidence gleaned(搜集) from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blem — and the same or worse could happen today. The ancient Egyptians depended on the Niles annual floods to irrigate their crops. But any change in climate that pushed the African monsoons(季风) southwards out of Ethiopia would have diminished these floods. Dwindling(逐渐变少；使变小) rains in the Ethiopian highlands would have meant fewer plants to establish the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment(沉积，沉积物) from the White Nile. The Blue Nile mud has a different isotope signature(名；特征) from that of the White Nile. So by analyzing isotope(同位素；核素) differences in mud deposited in the Nile Delta, Michael Krom of Leads University worked out what proportion of sediment Came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypts Old Kingdom. The weakened waters would have been catastrophic for the Egyptians.

Anything humans do to shift the climate belts would have an even worse effect along the Nile system because the populations have increased dramatically.

单选题 {{B}}For job seekers{{/B}} There is a new type of small advetisement becoming increasingly common in news- papers classified columns. It is sometimes placed among" situations vacant", although it does not offer anyone a job, and sometimes it appears among "situations wanted", al- though it is not placed by someone looking for a job either. What it does is to offer help in applying for a job. "Contact us before writing your application," or "Make use of our long experience in preparing your resume or job history," is how it is usually expressed. The growth and apparent success of such a specialised service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the resume (or job history), with the suggestion that it may now qualify as an art form in its own right. There was a time when job seekers simply wrote letters of application. "Just put down your name, address, age and whether you have passed any exams," was about the average level of advice offered to young people applying for their first jobs when they left school. The letter was really just for openers, it was explained, everything else could and should be saved for the interview. And in those clays of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest. Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. "Your search is over. I am the person you are looking for," was a widely used trick that occasionally succeeded. Or it might be some special feature specially designed for the job in view. There is no doubt, however, that it is the increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the resume.

单选题Man of Few Words Everyone chases success, but not all of us want to be famous. South African writer John Maxwell Coetzee is 1 for keeping to himself. When the 63-year-old man was named the 2003 Nobel Prize winner for literature, reporters were warned that they would find him "particularly difficult to 2 " Coetzee lives in Australia but spends part of the year teaching at the University of Chicago. He seemed 3 by the news that he won the US $1.3 million prize. "It came as a complete surprise. I wasn"t even aware they were due to make the announcement," he said. His 4 of privacy led to doubts as to whether Coetzee will attend prize-giving in Stockholm, Sweden, on December 10. But despite being described as 5 to track down, the critics agree that his writing is easy to get to know. Born in Cape Town, South Africa, to an English-speaking family, Coetzee 6 his break-through in 1980 with the novel "Waiting for the Barbarians".

单选题Medical Education In 18th- century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Paris, and Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King's College (now Columbia University), the first institution in the colonies to give the degree of doctor of medicine. Following the American Revolution, the Columbia medical faculty (formerly of King's College ) was combined with the College of Physicians and Surgeons ,chartered in 1809 ,which survives as a division of Columbia University. In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary schools of medicine(私人医学院)run for personal profit, most of which had low standards and poor facilities. In 1910 Abraham Flexner, the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools. Subsequently, the American Medical Association and the Association of American Medical Colleges laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals, and licensing of medical professionals that survive to this day. By the late 1980s the U. S. and Canada had 142 4 - year medical colleges recognized by the Liaison Committee on Medical Education to offer the M. D. degree; during the 1987 - 1988 academic year,47,262 men and 25,686 women entered these colleges and an estimated 11,752 men and 5, 958 women were graduated. Graduates, after a year of internship, receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners.

单选题 Early or Later Day Care The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive "attachment" period from birth to three may scar a child's personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion. Firstly, anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, in some tribal societies, such as the Ngoni, the father and mother of a child did not rear their infant alone—far from it. Secondly, common sense tells US that day care would not be so widespread today if parents care-takers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neural or slightly positive effect on children's development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue. But Bowlby's analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.
