The first considers that it was the unavoidable outcome of conflicting {{U}}(51) {{/U}} between Northern and Southern {{U}}(52) {{/U}}. The second blames it {{U}}(53) {{/U}} political leaders for {{U}}(54) {{/U}} to avert an unnecessary war. Analysts are also divided on whether the issue of slavery was the primary cause of the war, or a symptom of other, more {{U}}(55) {{/U}} differences—especially sectional interests and the doctrine of states' rights—between the North and South which had been developing since the formation of the American republic. The fundamental {{U}}(56) {{/U}} was economic. In the early 1840s the Northern states began the process of industrialization, modernizing their society to meet the demands of economic change. In {{U}}(57) {{/U}}, the slogan of Abraham Lincoln's Republican party, "free labour, free land, free man" encapsulated the ideology of valuing the freedom of individuals to grasp the {{U}}(58) {{/U}} for economic self-advancement in a booming, expanding society. The Southern states remained stubbornly {{U}}(59) {{/U}} both economically and socially. It was a backward-looking way of life of tall white mansions on great {{U}}(60) {{/U}} dependent on a labour system which made slaves of approximately 4 million black Americans. America was {{U}}(61) {{/U}} divided by economic structure, and was led into fratricidal(杀同胞的) warfare by a series of political clashes. The most common cause was the future of the West. The crises over California's admission in 1850 and over Kansas-Nebraska in 1854 were {{U}}(62) {{/U}} of the divergent economic interests of North and South in relation to the West. The North wanted free land for independent labour in the same new territories where the South {{U}}(63) {{/U}} to perpetuate its traditional way of life by extending slavery. The issue was not the slavery already practised, but the {{U}}(64) {{/U}} of its extension {{U}}(65) {{/U}} the West.

单选题第三篇 Unpredictable Earthquake Humans are forever forgetting that they can"t control nature. Exactly 20 years ago, a Time magazine cover story announced that "scientists are on the verge of being able to predict the time, place and even the size of earthquakes." The people of quake-ravaged (被地震破坏的) Kobe learned last week how wrong that assertion was. None of the methods conceived two decades ago has yet to discover a uniform wanting signal that preceded all quakes, let alone any sign that would tell whether the coming temblor (地震) is mild or a killer. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist (地震学家) at the California Institute of Technology. So, finding one all-purpose warning sign is impossible. One reason: Quakes tart deep in the earth, so scientists can"t study them directly. If a quake precursor were found, it would still be impossible to ward humans in advance of all dangerous quakes. Places like Japan and California are riddle with hundreds, if not thousands, of minor faults. Prediction would be less important if scientists could easily build structures to withstand tremors. While seismic engineering has improved dramatically in the past 10 to 15 years, every new quake reveals unexpected weakness in "quake-resistant" structures, says Terry Tullis, a geophysicist at Brown University. In Kobe, for example, a highway that opened only last year was damaged. In the Northridge earthquake, on the other hand, well-built structures generally did not collapse. A recent report in Science adds yet more anxiety about life on the faulty lines. Researchers Fan computer simulations to see how quake resistant buildings would fall in a moderate size temblor, taking into account that much of a quake"s energy travels in a large "pulse" of focused shaking. The results: both steel-frame buildings and buildings that sit on insulating rubber pads suffered severe damage. More research will help experts design stronger structures and possibly find quake precursors. But it is still a certainty that the next earthquake will prove once again that every fault cannot be monitored and every highway cannot be completely quake-proofed.

The appropriate use of eye contact (53) from one culture to another. In some cultures, women are (54) to lower their eyes in most communication (55) ; in others, younger people must keep their eyes lowered when addressing older people.

A speaker establishes friendly relationship with the audience mainly (65) eye contact, and good relationship is essential to the success of any speech.

单选题The National Trust The National Trust in Britain plays an increasingly important part in the preservation for public enjoyment of the best that is left unspoiled of the British countryside. Although the Trust has received practical and moral support from the Government, it is not a rich Government department. It is a voluntary association of people who care for the unspoiled countryside and historic buildings of Britain. It is charity which depends for its existence on voluntary support from members of the public. Its primary duty is to protect places of great natural beauty and places of historical interest. The attention of the public was first drawn to the dangers threatening the great old houses and castles of Britain by the death of Lord Lothian, who left his great seventeenth-century house to the Trust together with the 4,500-acre park and estate surrounding it. This gift attracted wide publicity and started the Trust"s "Country House Scheme". Under this scheme, with the help of the Government and the general public, the Trust has been able to save and make accessible to the public about one hundred and fifty of these old houses. Last year about one and three quarters of a million people paid to visit these historic houses, usually at a very small charge. In addition to country houses and open spaces the Trust now owns some examples of ancient wind and water mills, nature reserves, five hundred and forty farms and nearly two thousand five hundred cottages or small village houses, as well as some complete villages. In these villages no one is allowed to build, develop or disturb the old village environment in any way and all the houses are maintained in their original sixteenth-century style. Over four hundred thousand acres of coastline, woodland, and hill country are protected by the Trust and no development or disturbances of any kind are permitted. The public has free access to these areas and is only asked to respect the peace, beauty and wildlife. So it is that over the past eighty years the Trust has become a big and important organization and an essential and respected part of national life, preserving all that is of great natural beauty and of historical significance not only for future generations of Britons but also for the millions of tourists who each year invade Britain in search of a great historic and cultural heritage.

单选题Intelligence was believed to be a fixed entity, some faculty of the mind that we all possess and which determines in some way the extent of our achievements. Its value therefore, was as a predictor of children's future learning. If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious. Intelligence tests could be used for streaming children according to ability at an early age ; and atll these tests were superior to measurements of attainment for selecting children for different types of secondary education. "Streaming" in the paragraph most probably meansA. measuringB. learningC. educatingD. grouping
