Practice 1An Early History of Australia Before the arrival of European settlers, Aboriginal and Tortes Strait Islander peoples inhabited most areas of the Australian continent. Each people spoke one or more of hundreds of separate languages, with lifestyles and religious and cultural traditions that differed according to the region in which they lived. Adaptable and creative, with simple but highly efficient technology, Indigenous Australians had complex social systems and highly developed traditions reflecting a deep connection with the land and environment. Asian and Oceanic people had contact with Australia’s Indigenous peoples for thousands of years before the European expansion into the Eastern Hemisphere. Some formed substantial relationships with communities in northern Australia. In 1606, the Spanish explorer Luis Vaez de Torres sailed through the strait that separates Australia and Papua New Guinea. Dutch explorers charted the north and west coasts and found Tasmania. The first British explorer, William Dampier, landed on the northwest coast in 1688. But it was not until 1770 that his countryman, Captain James Cook, on the Endeavour, extended a scientific voyage to the South Pacific in order to chart the east coast of the continent that had become known as New Holland, and claimed it for the British Crown. The American war of independence shut off that country as a place to transport convicts, requiring Great Britain to establish a new penal colony. Sir Joseph Banks, the President of the Royal Society, had sailed as a naturalist with Captain Cook, and suggested Australia for this purpose. The First Fleet of 11 ships arrived at Botany Bay in January 1788. Governor Phillip preferred Sydney Harbor and the date he landed in the Harbor, 26 January, is now commemorated as Australia Day. The First Fleet carded 1,500 people, half of them convicts. Robert Hughes’ The Fatal Shore (1987) is a classic book on the convict system. Hughes suggests that the penal system had lasting effects on Australian society. About 160,000 convicts were sent to the Australian continent over the next 80 years. The wool industry and the gold rushes of the mid-19th century provided an impetus to free settlement. Scarcity of labor, the vastness of the bush and new wealth based on farming, mining and trade all contributed to the development of uniquely Australian institutions and sensibilities. At the time of European settlement in 1788 it is estimated there were at least 300,000 Aboriginals and Torres Strait Islanders in Australia. European settlement involved the displacement and dispossession of Indigenous peoples. It disrupted traditional land management practices and introduced new plants and animals into fragile Australian ecosystems.

Part CDirections:Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written clearly on ANSWER SHEET 2. (10 points)It is not easy to talk about the role of the mass media in this overwhelmingly significant phase in European history. History and news become confused, and one’s impressions tend to be a mixture of skepticism and optimism. 46) Television is one of the means by which these feelings are created and conveyed -- and perhaps never before has it served so much to connect different peoples and nations as is the recent events in Europe. The Europe that is now forming cannot be anything other than its peoples, their cultures and national identities. With this in mind we can begin to analyze the European television scene. 47) In Europe, as elsewhere, multi-media groups have been increasingly successful: groups which bring together television, radio newspapers, magazines and publishing houses that work in relation to one another. One Italian example would be the Berlusconi group, while abroad Maxwell and Murdoch come to mind.Clearly, only the biggest and most flexible television companies are going to be able to compete in such a rich and hotly-contested market. 48) This alone demonstrates that the television business is not an easy world to survive in, a fact underlined by statistics that show that out of eighty European television networks no less than 50% took a loss in 1989.Moreover, the integration of the European community will oblige television companies to cooperate more closely in terms of both production and distribution.49) Creating a “European identity” that respects the different cultures and traditions which go to make up the connecting fabric of the Old Continent is no easy task and demands a strategic choice -- that of producing programs in Europe for Europe. This entails reducing our dependence on the North American market, whose programs relate to experiences and cultural traditions which are different from our own.In order to achieve these objectives, we must concentrate more on co-productions, the exchange of news, documentary services and training. This also involves the agreements between European countries for the creation of a European bank for Television Production which, on the model of European Investment Bank, will handle the finances necessary for production costs. 50) In dealing with a challenge on such a scale, it is no exaggeration to say “Unity we stand, divided we fall” -- and if I had to choose a slogan it would be “Unity in our diversity.” A unity of objectives that nonetheless respect the varied peculiarities of each country.46) Television is one of the means by which these feelings are created and conveyed -- and perhaps never before has it served so much to connect different peoples and nations as is the recent events in Europe.

Australia is the world's smallest continent and largest island, a relatively young nation established in an ancient land. Its development represents a triumph(胜利)over remoteness and a harsh landscape.It is generally accepted that Australia's original inhabitants, the aboriginal(土著的)people, have lived on the continent for 40,000 to 60,000 years. They were also its sole(唯一的)human inhabitants until two centuries ago. Indonesian traders probably visited Australia's northwest but it was unknown to the rest of the world until the 1600s. A huge south land appeared on maps before 200 AD but its existence was not confirmed until the 17th century when Portuguese, Spanish and Dutch merchants ventured into Asia.The first European settlement of the continent--by the British--began in 1788, on the site now occupied by Sydney, Australia's largest city. There were then about 1500 Europeans and an estimated 300,000 aboriginal people in Australia. The population has reached 2.25 million by 1881, 5.41 million by 1921 and 7.4 million by the end of World War II(1945). It increased sharply, partly because of a large postwar immigration program, and reached more than 17 million in 1991, despite a decline that began in the 1970s in the natural increase and net immigration. The rate of population increase in the 40 years after world war II, about two percent, has halved.Australia is one of the most urbanized countries in the world, with about 70 percent of the population living in the 10 largest cities. Australians have a high standard of living by world standards. The flag of Australia is the only one to fly over a whole continent in the world. The small Union Jack represents the historical link with Britain, the largest star has six points for each of the states and one point for the territories, and the small stars form. the Southern Cross - a prominent of the southern hemisphere night sky.1. The passage is written to _____.A. present a general picture of AustraliaB. persuade people to travel in AustraliaC. tell people the history of AustraliaD. describe the characteristic of Australia2. The first sentence in paragraph 1 mainly suggests that _____.A. Australia is a strange countryB. it is not easy to find AustraliaC. Australia has contradictory(矛盾的)featuresD. Australia is a continent and a country as well3. Which statement about Australia's population can NOT be inferred? _____A. The population change is a gradual increase.B. The population increased rapidly for a time owing to the government's special policy.C. The rates of population increase in different periods varied.D. The rate of population increase before World War II was about one percent.4. The word urbanized means _____.A. of towns or citiesB. of emergencyC. of suburbsD. of the countryside5. Which of the following statements is NOT true? _____A. The large star on the flag of Australia has seven points.B.

Social change is more likely to occur in societies where there is a mixture of different kinds of people than in societies where people are similar in many ways. The simple reason for this is that there are more different ways of looking at things present in the first kind of society. There are more ideas, more disagreements in interest, and more groups and organizations with different beliefs. In addition, there is usually a greater worldly interest and greater tolerance in mixed societies. All these factors tend to protnote social change by opening more areas of life to decision.
In a society where people are quite similar in many ways, there are fewer occasions for people to see the need or the opportunity for change because everything seems to be the same. And although conditions may not be satisfactory, they are at least customary and undisputed.
Within a society, social changes is also likely to occur more frequently and more readily in the material aspects of the culture than in the non-material, for example, in technology rather than in values; in what has been learned later in life rather than what was learned early; in the less basic and less emotional aspects of society than in their opposites; in the simple elements rather than in the complex ones; in form rather than in substance; and in elements that are acceptable to the culture rather than in strange elements.
Furthermore, social change is easier if it is gradual. For example, it comes more readily in human relations on a continuous scale rather than one with sharp difference. This is one reason why change has not come more quickly to Black Americans as compared to other American minorities,because of the sharp difference in appearance between them and their white counterparts.
One of the factors that tend to promote social change is__________.A.joint interest
B.different points of view
C.less emotional people
D.advanced technology

century,the mysterious New World became for many people a genuine hope of a new life,an escape from
poverty and persecution,a chance to start again.We can say that,as a nation,America begins with that
hope.When,however,does American literature begin?
American literature begins with Amnerican experiences.Long before the first colonists arrived,before
Christopher Columbus，before the Northmen whofoundAmerica about the year 1000,Native Americans
lived here. Each trilbes literature was tightly woven into the fabric of daiiy life and reflected the unmistakably
American experience of lining with the land。Anoiher kind of experience,one filled with fear and excite-
ment,found its expression in the reports that Columbus and other explorers sent home in Spain,French and
English.In addition,the journals of the people who lived and died in the New England wilderness tell
unforgettable tales of hard and sometimes heartbreaking experiences of those early years.
Experience,then,is the key to early American literature.The New World provided a great variety of
experiences,and these experiences deniauded a wide variety of expressions by an even wider variety of early
American writers.These wnters included John Smith,who spent only two-and-a-half year on the American
continent.They included Jonathlan Edwards and William Byrd,who thought of themselves as British sub-
jects,never suspecting a revolution that would create a United States of America with a literature of its own.

问答题An Early History of Australia Before the arrival of European settlers, Aboriginal and Tortes Strait (托雷斯海峡) Islander peoples inhabited most areas of the Australian continent. Each people spoke one or more of hundreds of separate languages, with lifestyles and religious and cultural traditions that differed according to the region in which they lived. Adaptable and creative, with simple but highly efficient technology, Indigenous Australians had complex social systems and highly developed traditions reflecting a deep connection with the land and environment. Asian and Oceanic people had contact with Australia’s Indigenous peoples for thousands of years before the European expansion into the Eastern Hemisphere. Some formed substantial relationships with communities in northern Australia. In 1606, the Spanish explorer Luis Vaez de Torres sailed through the strait that separates Australia and Papua New Guinea (巴布亚新几内亚). Dutch explorers charted the north and west coasts and found Tasmania. The first British explorer, William Dampier, landed on the northwest coast in 1688. But it was not until 1770 that his countryman, Captain James Cook, on the Endeavour, extended a scientific voyage to the South Pacific in order to chart the east coast of the continent that had become known as New Holland, and claimed it for the British Crown. The American war of independence shut off that country as a place to transport convicts, requiring Great Britain to establish a new penal colony. Sir Joseph Banks, the President of the Royal Society, had sailed as a naturalist (博物学家) with Captain Cook, and suggested Australia for this purpose. The First Fleet of 11 ships arrived at Botany Bay in January 1788. Governor Phillip preferred Sydney Harbor and the date he landed in the Harbor,26 January, is now commemorated as Australia Day. The First Fleet carded 1,500 people, half of them convicts. Robert Hughes’ The Fatal Shore (1987) is a classic book on the convict system. Hughes suggests that the penal system had lasting effects on Australian society. About 160,000 convicts were sent to the Australian continent over the next 80 years. The wool industry and the gold rushes of the mid-19th century provided an impetus to free settlement.

问答题Directions:In this section, there is one passage followed by a summary. Read the passage carefully and complete the summary below by choosing no more than three words from the passage. Remember to write the answers on the Answer Sheet. Questions 1-5 are based on the following passage.The City of the Future What will city life be like in the future? Some people think that life in the cities is going to be horrible. They predict that cities will become more and more crowded. As the number of people increases, there will be less space for each person. This overcrowding will cause other problems—more crime, dirtier streets, and worse problems with traffic than we have now. How will people find enough drinking water, energy (such as gas and electricity), and housing? Because life will be hard, people who live in cities will worry more, and they may become sick. For these reasons, some say that nobody will want to live in urban areas. How can we solve such problems as overcrowding, crime, and traffic? In some cities, thousands of people are already sleeping in the streets because there is so little suitable housing—and because rents are so high. The crime rate isn’t going down. Instead, it is increasing so fast that many people are afraid to go out at night. Traffic is also getting worse. More and more often, traffic jams are so bad that cars don’t move at all for several blocks. These urban problems have been getting worse, not better, so many people see no hope for the future of the city. Los Angeles, California, for instance, has no subway system and the buses are slow. Instead, most commuters drive many miles from their homes to work. Many of these drivers spend several hours each day on busy freeways. New York, by contrast, has a mass transit system—buses, commuter trains, and subways. Because the public transportation is crowded and dirty, however, many people drive private cars, and the traffic jams are worse than in Los Angeles. On the other hand, some cities have clean, fast, and pleasant public transportation systems. In Paris, France, and Toronto, Canada, for example, anyone can use mass transit to move quickly from one part of the city to another. The disadvantages of any modern city are not unique to that city—that is, cities all over the world have to solve the problems of traffic jams, crime, housing, energy, drinking water, and overcrowding. Yet many cities have found answers to one or more of these difficulties. Some European cities, such as Stockholm, Sweden, or London, England, have planned communities that provide people with apartments, jobs, shopping centers, green space, entertainment, and transportation. Many U.S. cities are rebuilding their downtown areas. Urban planners can learn from one another. They can try solutions that have been successful in other parts of the world. Summary: Some people think that life in the cities is going to be horrible. They say that cities will become more and more crowded and many other problems will be caused by this 1 Due to the hard life, people do not want to live in 2 These urban problems such as overcrowding, crime and traffic have been getting worse, so many people 3 for the future of the city.

For example, 4 or London has planned communities providing people with apartments, jobs and so on. Besides, many U. S. cities 5 In a word, solutions that have been successful in a place should be adopted and tried in another place.

单选题Although many people would not believe it, the mosquito is actually the most dangerous animal in Africa. While the bite of the black mamba is invariably lethal when untreated, this dreaded snake kills only a few dozen people per year. Hippopotami, with their immense strength and foul dispositions, kill hundreds of people per year in rivers and lakes, but the mosquito is still more dangerous. Mosquitoes bite hundreds of millions of people in Africa every year, and they infect over a million each year with malaria, a disease that is often fatal. Which of the following questions would be most useful in evaluating the claim made above regarding the mosquito?A
Could a person survive an attack by a black mamba if that person received prompt medical attention?B
What criteria are used to determine which animal is the “most dangerous” animal?C
Could the incidence of mosquito bites be decreased through the judicious use of pesticides and insect repellent?D
Does malaria kill more people per year in Africa than tuberculosis?E
How does the percentage of people who survive hippopotamus attacks in Africa each year compare with the percentage of people who survive mosquito bites?

问答题Practice 2 Until recently, scientists knew little about life in the deep sea, nor had they reason to believe that it was being threatened. Now, with the benefit of technology that allows for deeper exploration, researchers have uncovered a remarkable array of species inhabiting the ocean floor at depths of more than 660 feet, or about 200 meters. At the same time, however, technology has also enabled fishermen to reach far deeper than ever before, into areas where bottom trawls can destroy in minutes what has taken nature hundreds and in some cases thousands of years to build. Many of the world's coral species, for example, are found at depths of more than 200 meters. It is also estimated that roughly half of the world's highest seamounts - areas that rise from the ocean floor and are particularly rich in marine life - are also found in the deep ocean. These deep sea ecosystems provide shelter, spawning and breeding areas for fish and other creatures, as well as protection from strong currents and predators. Moreover, they are believed to harbor some of the most extensive reservoirs of life on earth, with estimates ranging from 500,000 to 100 million species inhabiting these largely unexplored and highly fragile ecosystems.

问答题Practice 8 The United States has long been known as a “melting pot”, because many of its people are descended from settlers who came from all over the world to make their homes in the new land. The first immigrants in American history came from England and the Netherlands. Attracted by reports of great economic opportunities and religious and political freedom, immigrants from many other countries flocked to the United States in increasing numbers, reaching a peak in the years 1880—1914. Between 1820 and 1980 the United States admitted almost 50 million immigrants. Some 1,360,000 American Indians, descendants of North America's first inhabitants, now reside in the United States. Most live in the West, but many are in the south and north central areas. Of the more than 300 separate tribes, the largest is the Navaho in the Southwest. Black people were first brought to America from Africa as slaves. Their descendants now make up nearly 12 percent of the population. They once lived mainly in the agricultural South but now are scattered throughout the nation.
