问答题Oxford  When language learners arrive in Oxford, many ask where the university is, thinking that they will be shown just one building. It’s up to their teachers to explain that Oxford university is made up of a collection of many different colleges and institutions, each with its own history and characteristics.  There are many other surprises that learners discover about the city and its university. Katie Jennings is a social organizer at King’s St Joseph’s Hall in East Oxford, and it is her job to organize activities for learners outside of lesson time. She says many learners are surprised to discover that Oxford is a home to a wide variety of nationalities and ethnic groups, and one of the most popular social events is a night out at one of the town’s Latin American dance clubs. After a day spent learning English and absorbing the ancient atmosphere of the university, learners can samba the night away.  The city also has a thriving Asian community, and the sight of women in saris is as common in Oxford’s streets as academics in gowns and mortarboards. There is also a mouth-watering selection of Asian restaurants serving curries, as well as shops stocked with exotic vegetables and fruits.  The city has attracted such a diverse population not only because of the university, but also because it is an important industrial centre which is known for car manufacturing among other things. In spite of large industrial areas, the old of the city centre has remained surprisingly intact.  Carmel Engin, who teaches at the Lake School, says many learners are surprised to find that the city is free from the usual high-rise modern buildings. “From the centre of Oxford, you can see green hills in the distance, and this will make learners deeply feel that they are in a small, friendly town, but not just another modern metropolis.”  Some learners will be tempted to explore those green hills—Oxford is surrounded by some of the most beautiful countryside in southern England—but, as Engin admits, with so much to do and see in the city, few learners find the time, to explore its surroundings.

问答题A Nation of Immigrants Composed Mainly of the White People  The United States of America has long been known as a nation of immigrants and a “melting pot”, because the great majority of its people are immigrants and descendants of settlers who came from all over the world to make their homes in the new land, seeking their dream in America. The  first immigrants in American history came from England and the Netherlands. Now the descendants of European immigrants make up 80.3% of the American population of about 250 million.  English colonization in North America in the sixteenth century repeatedly failed. It was not until 1607 that the first English permanent settlement in America was establish. The first wave of colonizing activity, which began in 1606 and lasted until 1637, planted three groups of English colonies: Virginia and Maryland on the Chesapeake, the Puritan commonwealths of New England, and the British West Indies, and also the Dutch colony of New Netherlands, which became New York. Some other European countries also established their colonies along North America’s Atlantic coastline. In 1713, the population of the twelve continental colonies was nearly 360,000, a fourfold increase. Quite a lot of them were German and Scots-Irish. Discontented Germans came to English America because the German states had no overseas possessions, and no colonies except those of the English would admit foreigners. Most Germans entered America at Philadelphia, whence they spread out fanwise into the back-country and became the most prosperous farmers in North America. The English-speaking Scots-Irish came from Ulster. They were largely descendents of the Scots who had colonized Northern Ireland when the English were first setting Virginia. After 1713 the pressure of the native Catholic Irish and the restrictive legislation of the British. Parliament forced them to emigrate in drove. As land was dear in the eastern colonies, these fighting Celts drifted to the frontier. A considerable number of southern Irish, mostly Protestants but including Catholic families came at the same time. They were mostly men of property who invested in land and remained in the older-settled regions.  Britain gradually established its dominance over North America’s Atlantic coast. It successfully planted 13 colonies by edging out other colonial powers and by driving off the native Indians. Though the first English permanent settlement in America was established in Jamestown in1607, modem America was established in Jamestown in 1607, modem Americans choose to look back to the Pilgrim Father, a group of Puritans who came from England in 1620 for a symbol of the origin of their new country. They were followed by other Englishmen. They were generally known as the White Anglo-Saxon Protestants (WASP), who played the leading role in winning America’s independence. Their mother tongue, English, became the official language of the new nation. Today about 33% of Americans are of British origin. They control most of the national wealth and political power. The other white Americans, whose forefathers were from other European countries, are not so influential as the WASPs. All these white European immigrants and their descendants together constitute the majority of the American population.  After the American Civil War, a large number of the “new immigrations” came to the United States of America. Even during the Civil War some 800,000 immigrants had entered the United States, and in the ten years after the ending of the war, some 3.25 million immigrants flooded into the cities and the farms of the North and the West. In the single generation from 1880 to 1910 a tidal wave of immigration spilled almost 18 million persons on American shores. Unlike the old immigrations, who were “pushed out” of West Europe by religious persecution or impoverishment, the new immigrations were “pulled to” the United States by the prospect of good jobs and happy life. Most of them were unskilled. The large influx of the new immigrations resulted in the adoption of the Immigration Quota Law by the American government.  A lot of Chinese coolies were brought into America after the discovery of gold in California. and for the construction of the Central Pacific Railroad. The Chinese-Americans made a great contribution to the development of the American West. But, Chinese-Americans and other Asian-Americans never constitute a majority of the American population. The United States has always been a nation of immigrants composed mainly of the white people.  Immigrants from different nations all over the world joined together to make one nation, the American. They speak almost the same kind of English with far less class or regional variety than in Great Britain. They have the same way of life, similar habits and manners. They have established a new universal national culture. With only a few exceptions, the national origins have well been mixed. In this sense, the United States of America has been known as a “melting pot”.

问答题The Threatened Environment  In recent years we have come to realize that several threats to the environment are fundamental. One is acid rain, which is created by the millions of tones of sulphur dioxide and nitrogen oxides spewed out of North American smokestacks and automobile exhaust pipes1. The oxides mix with water vapor in the air to form weak sulphuric and nitric acid, which later falls as acid rain. The result is increased acidity in lakes, which has curtailed the ability of many fish to reproduce, and in the soil, which has slowed the growth of trees and increased their vulnerability to disease.2  With every news report, the externality dimension of environmental problems3 seems to become clearer. For instance, it was recently reported that Lapp villagers in northern Sweden and Norway were forbidden to eat local reindeer meat after their herds became contaminated by fallout from the nuclear accident at ChernobyI5 in far-off Ukraine. Similarly, Canadian wildlife scientists have found high levels of PCBs6 and other contaminants in polar-bear livers.  But some pollution problems involve such dramatic externalities that the whole world is affected. One example is the greenhouse effect. The steadily rising and essentially irreversible concentration7 of carbon dioxide in the earth’s atmosphere causes it to trap increasing amounts of the heat radiated by the planet. The general warming trend is expected to have disastrous effects, including mass starvation in some less developed countries, flooding of entire coastal areas, and severe droughts on the Canadian Prairies, perhaps within the next fifty years.  Another worldwide threat is in the upper atmosphere—the thinning of the layer of ozone, a bluish gas that shields the earth from the sun’s ultraviolet rays. Synthetic chemicals called chlorofluorocarbons (CFCs) are depleting the ozone layer. One estimated result is that the chance of getting skin cancer is now 8 to 16 percent greater than it was in 1950.  Hazardous wastes (such as those from nuclear plants, industrial manufacturing, laboratories, and medical institutions) represent yet another critical environmental problem improperly disposed, they can threaten all forms of organic life. Unfortunately, little has been done so far to solve this problem. Indeed there are many instances in which industrialized countries have literally just shipped the problem off to the poorest of the less developed countries—countries unequipped with the necessary storage and treatment facilities, and certainly too poor to deal with the serious environmental problems that will follow. For example, in 1988 the government of Guinea-Bissau13 signed a contract with two British firms to receive 15 million tones of pharmaceutical wastes over a five-year period. While this arrangement was very inexpensive from the firms’ point of view, the payments to Guinea-Bissau totaled more than four times that county’s national product. It makes it difficult to solve the problem when parts of the world are so poor that they are forced to regard such transactions as “good deals”.  The users of the world’s resources simply must be made to take the external costs of their actions into consideration when making their decisions. The people who are hacking down the world’s rain forests at the rate of 1200 hectares an hour are literally cutting away the lungs of the earth, since rain forests contribute a large percentage of the oxygen in the earth’s atmosphere. But these individuals are not necessarily evil: in many cases, they are forced to overuse the environment for their own or their country’s immediate survival. For example, some developing countries’ needs for foreign exchange to pay for imports compel them to cut timber faster than it can be regenerated. They simply cannot afford to worry about the future.  Obviously, many of these problems cannot be solved without political decisions to redistribute income to the less developed countries, and to define property rights. But the right kinds of political and institutional changes will be forthcoming only if they are rooted in an understanding of the externality dimension of environmental issues.

问答题The Grand Canyon  A famous American John Muir said in 1898:“The Grand Canyon…as unearthly in the color and grandeur(宏大)and quantity of its architecture as if you had found it after death on some other star. ”  Like Muir, those of us who stand along the rim are prompted to wonder about the unearthliness and the forces that created and are still changing this place.  After more than 100 years of studies, many things are still obscure. Today visitors come by the thousands—the great and simple of the earth — all in a spirit of marvel. Travelers come from every state of the Union, from every country in Europe and Asia, pilgrims(朝圣者)to a shrine(神殿)that is the same as the creed(信仰).  From the depths of the canyon(峡谷)comes welling silence. Seldom can you hear the roar of the river. For all sounds are swallowed in this gulf of space. ‘It makes one want to murmur. A woman once whispered to her companion. This silence is not the silence of death;rather, it is a presence. It is like a great piece of music. But music made of man works up to a climax and ceases;the Grand Canyon is all climax, a chord(和音)echoing into eternity. Perhaps the most spectacular feature of the Grand Canyon, its Redwall limestone(石灰石) cliff, stands about half way up the chasm (裂口) and is practically vertical. Its average height is550 feet almost exactly that of the Washington Monument. Though it is actually gray-blue limestone, the surface of the cliff has been stained to a sunset hue by iron salts washing out of the rocks. Above the Redwall come alternating layers of red sandstone and shale(页岩)1, 000 feet thick, then comes the next pale-blue layer. The topmost layers are a yellowish limestone.  Now, visitors to the South Rim alone may number 18, 000 in a single day. Some of that number will travel by mule(轻型牵引机)train down Bright Angel Trail to the canyon’s floor, cross the raging fiver by a suspension bridge and amount to the North Rim.  Though the two rims face each other across only 12 miles, it is a journey of 214 miles by car from one to the other. Nor can you visit the North Rim except in summer;some 1, 200 feet higher than the South Rim, it is snow covered much of the year except in July and August.  But there is no day that you may not visit the South Rim and find the sun warm on your face and the air perfumed with the incense of smoke from an Indian hearth. The Grand Canyon is an unearthly sight. No wonder an American writer and journalist said, “I came here an atheist(无神论者), and departed a devout (虔诚的) believer. ”

问答题Elysee Palace  The Elysee Palace in France enjoys equal popularity in the world with the Buckingham Palace in the United Kingdom, the Kremlin in Russia as well as the White House in the U. S. A. It is the residence of the president of the French Republic and the symbol of the supreme authority in France.  The Elysee Palace, with an area of 11, 000 square meters, is at3 the eastern end of the Champs Elysee in3 the bustling city of Paris proper and backed by a large and tranquil garden of more than twenty thousand square meters. Its main building, quite handsome and graceful, is a two-story classical stone architecture of European style, flanked by two side buildings facing each other and with an extensive rectangular courtyard in the middle. There are altogether 369 halls and rooms of different sizes.  The Elysee Palace, built in 1718, has a long history of close to 300 years to date. This house was at first a orivate residence of a count named d’Evreau, hence it was called Hotel d’Evreau. It had later gone through many vicissitudes and its owners had been changed for many times, but all the dwellers in it were distinguished personages and high officials. The house was renamed Bonaparte Mansion when6 it was owned by Louis XV and Louis XVI successively when they acted as emperors. Napoleon I signed his act of abdication here when he suffered crushing defeat in the Battle of Waterloo in 1815. Napoleon III moved in the Mansion in 1848 when he was elected president, and the house became a Royal Palace when he proclaimed himself as emperor. The Third French Republic issued a decree in 1873, designating officially the Elysee Palace as the residence of president of the French Republic. Over the hundred odd years since then, almost all the presidents of the French Republic worked and lived there. Starting from 1989, the Elysee Palace is open to the public every year in September on the French Castles Day.
