单选题{{B}}Text 1{{/B}} Scholars and students have always been great travellers. The official case for "academic mobility" is now often stated in impressive terms as a fundamental necessity for economic and social progress in the world, and debated in the corridors of Europe, but it is certainly nothing new. Serious students were always ready to go abroad in search of the most stimulating teachers and the most famous academies; in search of the purest philosophy, the most effective medicine, the likeliest road to gold. Mobility of this kind meant also mobility of ideas l their transference across frontiers, their simultaneous impact upon many groups of people. The point of learning is to share it, whether with students or with colleagues; one presumes that only eccentrics have no interest in being credited with a startling discovery, or a new technique. It must also have been reassuring to know that other people in other parts of the world were about to make the same discovery or were thinking along the same lines, and that one was not quite alone, confronted by inquisition, ridicule or neglect. In the twentieth century, and particularly in the last 20 years, the old footpaths of the wandering scholars have become vast highways. The vehicle which has made this possible has of course been the aeroplane, making contact between scholars even in the most distant places immediately feasible, and providing for the very rapid transmission of knowledge. Apart from the vehicle itself, it is fairly easy to identify the main factors which have brought about the recent explosion in academic movement. Some of these are purely quantitative and require no further mention: there are far more centres of learning, and a far greater number of scholars and students. In addition one must recognise the very considerable multiplication of disciplines, particularly in the sciences, which by widening the total area of advanced studies has produced an enormous number of specialists whose particular interests are precisely defined. These people would work in some isolation if they were not able to keep in touch with similar isolated groups in other countries. Frequently these specialisations lie in areas where very rapid developments are taking place, and also where the research needed for developments is extremely costly and takes a long time. It is precisely in these areas that the advantages of collaboration and sharing of expertise appear most evident. Associated with this is the growth of specialist periodicals, which enable scholars to become aware of what is happening in different centres of research and to meet each other in conferences and symposia. From these meetings come the personal relationships which are at the bottom of almost all formalized schemes of cooperation, and provide them with their most satisfactory stimulus. But as the specialisations have increased in number and narrowed in range, there had been an opposite movement towards interdisciplinary studies. These owe much to the belief that one cannot properly investigate the incredibly complex problems thrown up by the modern world, and by recent advances in our knowledge along the narrow front of a single discipline. This trend has led to a great deal of academic contact between disciplines, and a far greater emphasis on the pooling of specialist knowledge, reflected in the broad subjects chosen in many international conferences.

单选题From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous disease. A large number of once fatal illness can now be found for the most stubborn remaining disease. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of them, women and children on the roads Man versus the motor-car! It is a never-ending battle which man is losing Thousand of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen. It has been rightly said that when a man is sitting behind a steering wheel, his ear becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind steering wheel. They swear, they are ill-mannered and aggressive, willful as two-year-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving. The surprising thing is that the society smiles so gently on the motorist and seems to forgive his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some of the things that might be done. The driving test should be standardized and made for more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person's driving ability. Present drinking and driving laws (where they exist) should be made much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should he banned. These measures may sound inordinately harsh. But surely nothing should be considered as too severe if it results in reducing the annual toll of human life. After all, the world is for human beings not for motor-cars.

单选题When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cool .Why? The sun makes the earth hot, but it cannot make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth rises. Then the cool air over the water moves in and takes the place of the hot air. When you are near a lake or an ocean, you feel the cool air when it moves in. You feel the wind. And the wind makes you cool. Of course, scientists cannot answer all of your questions. If we ask, "why is the ocean full of salt?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into the cracks. The rain then carries the salt into the earth and then into the rivers. The rivers carry the salt into the ocean. But then we ask, "what happens to the salt in the ocean? The ocean does not get more salty every year." Scientists are not sure about the answer to this question. We know a lot about our world. But there are still many answers that we do not have, and we are curious.

单选题{{B}}Part A{{/B}}Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D． {{B}}Text 1{{/B}} It is the world's fourth-most-important food crop, after maize, wheat and rice. It provides more calories, more quickly, using less land and in a wider range of climates than any Other plant. It is, of Course, the potato. The United Nations has declared 2008 the International Year of the Potato. It hopes that greater awareness of the merits of potatoes will contribute to the achievement of its Millennium Development Goals, by helping to alleviate poverty, improve food security and promote economic development. It is always the international year of this or month of that. But the potato's unusual history means it is well worth celebrating by readers of The Economist because the potato is intertwined with economic development, trade liberalisation and globalisation. Unlikely though it seems, the potato promoted economic development by underpinning the industrial revolution in England in the 19th century. It provided a cheap source of calories and was easy to cultivate, so it liberated workers from the land. Potatoes became popular in the north of England, as people there specialised in livestock farming and domestic industry, while farmers in the south (where the soil was more suitable ) concentrated on wheat production. By a happy accident, this concentrated industrial activity in the regions where coal was readily available, and a potato-driven population boom provided ample workers for the new factories. Friedrich Engels even declared that the potato was the equal of iron for its "historically revolutionary role". The potato promoted free trade by contributing to the abolition of Britain's Corn Laws-the cause which prompted the founding of The Economist in 1843. The Corn Laws restricted imports of grain into the United Kingdom in order to protect domestic wheat producers. Landowners supported the laws, since cheap imported grain would reduce their income, but industrialists opposed them because imports would drive down the cost of food, allowing people to spend more on manufactured goods. Ultimately it was not the eloquence of the arguments against the Corn Laws that led to their abolition-and more's the pity. It was the tragedy of the Irish potato famine of 1845, in which 1million Irish perished when the potato crop on which they subsisted succumbed to blight. The need to import grain to relieve the situation in Ireland forced the government, which was dominated by landowners who backed the Corn Laws, to reverse its position. This paved the way for liberalisation in other areas, and free trade became British policy. As the Duke of Wellington complained at the time, "rotten potatoes have done it all. " In the form of French fries, served alongside burgers and Coca-Cola, potatoes are now an icon of globalisation. This is quite a turnaround given the scepticism which first greeted them on their arrival in the Old World in the 16th century. Spuds were variously thought to cause leprosy, to be fit only for animals, to be associated with the devil or to be poisonous. They took hold in 18th century Europe only when war and famine meant there was nothing else to eat; people then realised just how versatile and reliable they were. As Adam Smith, one of the potato's many admirers, observed at the time, "The very general use which is made of potatoes in these kingdoms as food for man is a convincing proof that the prejudices of a nation, with regard to diet, however deeply rooted, are by no means unconquerable. " Mashed, fried, boiled and roast, a humble tuber changed the world, and free-trading globalisers everywhere should celebrate it.
