单选题 In the longest-term study of its kind, researchers pitted two popular diets head to head—a low-fat American Heart Association-style diet and a carb-controlled Mediterranean diet, each combined with regular physical activity—in a population of overweight patients who had Type 2 diabetes. Researchers found that over the four-year study, patients who adhered to the Mediterranean-style eating plan maintained lower blood-sugar levels for a longer time than those in the low-fat-diet group. The Mediterranean dieters were also able to maintain slightly more weight loss than the low-fat group and showed small improvements in triglyceride and HDL cholesterol levels, both risk factors for heart disease. On the basis of their finding, the study's authors suggest that some diabetes patients may be able to substitute diet and exercise for blood-sugar-lowering medications. "A Mediterranean-style diet is a very important part in the treatment of diabetes. We knew that, " says Dr. Loren Greene, a New York University Medical Center endocrinologist, who was not involved in the study. "But there just hasn't been a good study to confirm this before." The current study does not make clear, however, whether diet alone can reduce blood sugar enough to eliminate the use of diabetes medication or whether it is even advisable to forgo medication at all. Participants in the new study were kept off drugs when their AIC levels—a measurement that indicates a patient's blood-sugar levels over the previous three months—were below 7%, the standard cutoff for what is considered controlled blood sugar. But "we don't know for sure if people with AIC levels under 7% still need to be on drugs, " says Greene. "The research just hasn't answered that question yet." Recent studies suggest that using blood-sugar-controlling medication even among the 57 million Americans who have pre-diabetes—meaning they have elevated, but not dangerously high blood sugar and are at very high risk of developing diabetes— may prevent the development of heart disease an stroke. While diabetes doctors generally agree that the first line of defense against Type 2 diabetes should always be exercise and diet, many recommend also using drugs. For its part, the American Diabetes Association advises patients with Type 2 diabetes to make appropriate lifestyle changes and to start a drug regimen immediately upon diagnosis. Still, many doctors acknowledge patients' aversion to chronic drug-taking." Almost universally, people don't want to take medicine if they can avoid it, " says Greene. And physicians point out that the direct and indirect costs associated with taking a drug—even one as widely prescribed as the generic diabetes medication metformin(二甲双胍,一种抗糖尿病和降血糖药)—can serve as a barrier for many patients, especially among disadvantaged populations and those without health insurance. Whether avoidance of medication in certain cases proves to be reasonable, for now it can at least be used as an effective incentive to improve lifestyle habits, says Greene: "If you are told, 'If you don't want to go on medicine, stick to this diet, ' then that's a pretty valuable tool at least for patient compliance."

单选题Violent criminals with something to hide have more reason than ever to be paranoid about a tap on the shoulder which could send them to jail. Queensland police are working through a backlog of unsolved murders with some dramatic success. Greater cooperation between the public and various law enforcement agencies is playing a role, but new genetic-testing techniques are the real key to providing the vital evidence to mount a prosecution. Evidence left behind at the scene of any murder is guaranteed to outlive the person who left it. A blood, saliva or tissue sample in the size of a pin, kept dry and out of sunlight, will last several thousand years. From it, scientific analysis now can tell accurately the sex of the person who left it. When matched against a sample from a crime suspect, it can indicate with million-to-one certainty whether the samples come from the same source. Only twins share identical DNA. So precise is the technology if the biological parents of a suspect agree to provide a sample, forensic scientists can work out the rest for themselves without cooperation from the suspect. Queensland forensic scientists have been using the DNA testing technology since 1992, and last year they were recognized internationally for their competence in positive individual identification. That is part of the reason 20 of Queensland's most puzzling unsolved murders dating to 1932 are being ac timely investigated. There also have been several recent arrests for unsolved murders. Forensic evidence was instrumental in charges being laid over the bashing death of waitress Tasha Douty on Brampton Island in 1983. Douty's blood-splattered, naked body was found on a nude sunbathing beach at Dinghy Bay on the island. Footprints in the sand indicated that the killer had grappled with the 21-year-old mother who had fled up the beach before being caught and beaten to death. According to Leo Freney, the supervising forensic scientist at the John Tonge Centre at Brisbane's Griffith University, DNA testing has become an invaluable tool for police, its use is in identifying and rejecting suspects. In fact, he says, it eliminates more people than it convicts. " It is easily as good as fingerprints for the purpose of identification, " he says. "In the case of violent crime it is better than fingerprints. You can't innocently explain things like blood and semen at a crime scene where you may be able to innocently explain fingerprints. " In Queensland, a person who has been arrested on suspicion of an offence can be taken before a magistrate and ordered to provide a sample of body fluid by :force if necessary.

单选题The earth is witnessing an urban revolution, as people worldwide crowd into towns and cities. In 1800 only five percent of the world's population were urban dwellers; now the proportion has risen to more than forty-five percent, and by the year 2010 more people will live in towns and cities than in the countryside. Humanity will, for the first time, have become a predominantly urban species. Though the world is getting more crowded by the day, absolute numbers of population are less important than where people concentrate and whether these areas can cope with them. Even densities, however, tell us nothing about the quality of the infrastructure--roads, housing and job creation, for exampleor the availability of crucial services. The main question, then, is not how many people there are in a given area, but how well their needs can be met. Density figures have to be set beside measurements of weaith and employment, the quality of housing and the availability of education, medical care, clean water, sanitation and other vital services. The urban revolution is taking place mainly in the Third World, where it is hardest to accommodate. Between 1950 and 1985 the number of city dwellers grew more than twice as fast in the Third World as in industrialized countries. During this period, the urban population of the developed world increased from 477 million to 838 million, less than double; but it quadrupled in developing countries, from 286 million to 1.14 billion. Africa's urban population is racing along at five percent a year on average, doubling city numbers every fourteen years. By the turn of the century, three in every four LatinAmericans will live in urban areas, as will two in every five Asians and one in every three Africans. Developing countries will have to increase their urban facilities by two thirds by then, if they are to maintain even their present inadequate levels of services and housing. In 1940 only one out of every hundred of the world's people lived in a really big city, one with a population of over a million. By 1980 this proportion had already risen to one in ten. Two of the world's biggest cities, Mexico and Sao Paulo, are already bursting at the seams--and their populations are doubling in less than twenty years. About a third of the people of the Third World's cities now live in desperately overcrowded slums and squatter settlements. Many are unemployed, uneducated, undernourished and chronically sick. Tens of millions of new people arrive every year, flocking in from the countryside in what is the greatest mass migration in history. Pushed out of the countryside by rural poverty and drawn to the cities in the hope of a better life, they find no houses waiting for them, no water supplies, no sewerage, no schools. They throw up makeshift hovels, built of whatever they can find: sticks, fronds, cardboard, tarpaper, straw, petrol tins and, if they are lucky, corrugated iron. They have to take the land none else wants; land that is too wet, too dry, too steep or too polluted for normal habitation. Yet all over the world the inhabitants of these apparently hopeless slums show extraordinary enterprise in improving their lives. While many settlements remain stuck in apathy, many others are gradually improved through the vigour and cooperation of their people, who turn flimsy shacks into solid buildings, build school, lay out streets and put in electricity and water supplies. Governments can help by giving the squatters the right to the land that they have usually occupied illegally, giving them the incentive to improve their homes and neighborhoods. The most important way to ameliorate the effects of the Third World's exploding cities, however, is to slow down the migration. This involves correcting the bias most governments show towards cities and towns and against the countryside. With few sources of hard currency, though, many governments in developing countries continue to concentrate their limited development efforts in cities and towns, rather than rural areas, where many of the most destitute live. As a result, food production falls as the countryside slides ever deeper into depression. Since the process of urbanization concentrates people, the demand for basic necessities, like food, energy, drinking water and shelter, is also increased, which can exact a heavy toll on the surrounding countryside. High-quality agricultural land is shrinking in many regions, taken out of production because of overuse and mismanagement. Creeping urbanization could aggravate this situation, further constricting economic development. The most effective way of tackling poverty, and of stemming urbanization, is to reverse national priorities in many countries, concentrating more resources in rural areas where most poor people still live. This would boost food production and help to build national economies more securely. Ultimately, though, the choice of priorities comes down to a question of power. The people of the countryside are powerless beside those of the towns; the destitute of the countryside may starve in their scattered millions, whereas the poor concentrated in urban slums pose a constant threat of disorder. In all but a few developing countries the bias towards the cities will therefore continue, as will the migrations that are swelling their numbers beyond control.

Mark your answers on ANSWER SHEET 1.{{B}}Text 1{{/B}} More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving. As Skolnick notes, Americans are a marrying people: Relative to Europeans, more of us marry and we marry at a younger age. Moreover, aster a decline in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce rate needs to be taken in this pro-marriage context: some 80 percent of divorced individuals remarry. Thus, marriage remains, by far, the preferred way of life for the vast majority of people in our society. What has changed more than marriage is the nuclear family. Twenty-five years ago, the typical American family consisted of a husband, a wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children. And there are many marriages where at least some of the children are from the wife's previous marriage, or the husband's, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses. Thus, one can find the very type of family arrangement. There are marriages without children; marriages with children from only the present marriage; marriages with "full-time" children from the present marriage and "part-time" children from former marriages. There are step-fathers, step-mothers, half-brothers, and half-sisters. It is not all that unusual for a child to have four parents and eight grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: Most Americans spend most of their adult lives married.
