BxP^^¼8@´cforum.liuxuehome.com$WȦé/ÌìQuestion 1-9
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Although social changes in the United States were being wrought throughout most of the nineteenth-century,, public awareness of the changes increased to new levels in the 1890 s. The acute, growing public awareness of the social changes that had been taking place for some time was tied to tremendous growth in popular journalism in the late nineteenth century, including growth in quantity and circulation of both magazines and newspapers. These developments, in addition to the continued growth of cities, were significant factors in the transformation of society from one characterized by relatively isolated self-contained communities into an urban, industrial nation. The decade of the 1870 s, for example, was a period in which the sheer number of newspapers doubled, and by 1880 the New York Graphic had published the first photographic reproduction in a newspaper, portending a dramatic rise in newspaper readership. Between 1882 and 1886 alone, the price of daily newspapers dropped from four cents a copy to one cent, made possible in part by a great increase in demand. Further more, the introduction in 1890 of the first successful linotype machine promised even further growth. In 1872 only two daily newspapers could claim a circulation of over 100,000,but by 1892 seven more newspapers exceeded that figure. A world beyond the immediate community was rapidly becoming visible.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì But it was not newspapers alone that were bringing the new awareness to people In the United States in the late nineteenth century. Magazines as they are known today began publication around 1882, and, in fact, the circulation of weekly magazines exceeded that of newspapers in the period which followed. By 1892, for example, the circulation of the Ladies Home Journal had reached an astounding 700,000. An increase in book readership also played a significant part in this general trend. For example, Edward Bellamy s utopian novel, Looking Backward, sold over a million copies in 1888, giving rise to the growth of organizations dedicated to the realization of Bellamy s vision of the future. The printed word, unquestionably. was intruding on the insulation that had characterized United Slates society in an earlier period.

BxP^^¼8@´cforum.liuxuehome.com$WȦé/ÌìQuestion 10-19
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Glass is a remarkable substance made from the simplest raw materials. It can be colored or colorless, monochrome or polychrome, transparent, translucent, or opaque. It is lightweight impermeable to liquids, readily cleaned and reused , durable yet fragile, and often very beautiful Glass can be decorated in multiple ways and its optical properties are exceptional. In all its myriad forms - as table ware, containers, in architecture and design - glass represents a major achievement in the history of technological developments.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Since the Bronze Age about 3,000 B.C., glass lias been used for making various kinds of objects. It was first made from a mixture of silica, line and an alkali such as soda or potash, and these remained the basic ingredients of glass until the development of lead glass in the seventeenth century. When heated , the mixture becomes soft and malleable and can be formed by various techniques into a vast array of shapes and sizes. The homogeneous mass thus formed by melting then cools to create glass, but in contrast to most materials formed in this way (metals, for instance), glass lacks the crystalline structure normally associated with solids, and instead retains the random molecular structure of a liquid. In effect, as molten glass cools, it progressively stiffens until rigid, but does so without setting up a network of interlocking crystals customarily associated with that process. This is why glass shatters so easily when dealt a blow. Why glass deteriorates over time, especially when exposed to moisture, and why glassware must be slowly reheated and uniformly cooled after manufacture to release internal stresses Induced by uneven cooling.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Another unusual feature of glass is the manner in which its viscosity changes as it turns from a cold substance into a hot, ductile liquid. Unlike metals that flow or "freeze" at specific temperatures glass progressively softens as the temperature rises, going through varying stages of malleability until it flows like a thick syrup. Each stage of malleability allows the glass to be manipulated into various forms, by different techniques, and if suddenly cooled the object retains the shape achieved at that point. Glass is thus amenable to a greater number of heat-forming techniques than most other materials.

BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì转贴于:考试大_托福考试 Question 20-30 BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì A great deal can be learned from the actual traces of ancient human locomotion: the footprints of early hominids. The best-known specimens are the remarkable tracks discovered at Lactoli, Tanzania, by Mary Leaky. These were left by small hominids around 3.6 to 3.75 million years ago, according to potassium - argon dates of the volcanic rocks above and below this level. These hominids walked across a stretch of moist volcanic ash, which was subsequently turned to mud by rain, and which then set like concrete.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Examination of he shape of the prints revealed to Mary Leakey that the feet had a raised arch, a rounded heel, a pronounced ball, and a big toe that pointed forward. These features, together with the weight-bearing pressure patterns, resembled the prints of upright-walking modern humans. The pressures exerted along the foot, together with the length of stride, which averaged 87 centimeters, indicated that the hominids had been walking slowly. In short, all the detectable morphological features implied that the feet that left the footprints were very little different from those of contemporary humans.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì A detailed study has been made of the prints using photogrammetry, a technique for obtaining measurements through photographs, which created a drawing showing all the curves and contours of the prints. The result emphasized that there were at least seven points of similarity with modern bipedal prints, such as the depth of the heel impression, and the deep imprint of the big toe. M Day and E. Wickens also took stereophotographs of the Lactoli prints and compared them with modern prints make by men and women in similar soil conditions. Once again, the results furnished possible evidence of bipedalism. Footprints thus provide us not merely with rare impressions of the soft tissue of early hominids, but also with evidence of upright waling that in many ways is clearer than can be obtained from the analysis of bones.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì The study of fossil footprints is not restricted to examples from such remote periods. Hundreds of prints are known, for example, in French caves dating from the end of the last ices age, approximately 10,000 years ago. Research by Leon Pales, using detailed silicon resin molds of footprints mostly made by bare feet, has provided information about this period.

BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì转贴于:考试大_托福考试 Questions 31-40 BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì The livelihood of each species in the vast and intricate assemblage of living things depends on the existences of other organisms. This interdependence is sometimes subtle, sometimes obvious. Perhaps the most straight forward dependence of one species on another occurs with parasites, organisms that live on or in other living things and derive nutrients directly from them. The parasitic way of life is widespread. A multitude of microorganisms( including viruses and bacteria) and an army of invertebrates - or creatures lacking a spinal column (including crustaceans, insects, and many different types of worms ) -make their livings directly at the expense of other creatures. In the face of this onslaught, living things have evolved a variety of defense mechanisms for protecting their bodies from invasion by other organisms.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Certain fungi and even some kinds of bacteria secrete substances known as antibiotics into their external environment. These substances are capable of killing or inhibiting the growth of various kinds of bacteria that also occupy the area, thereby eliminating or reducing the competition for nutrients. The same principle is used in defense against invaders in other groups of organisms. For example, when attacked by disease-causing fungi or bacteria, many kinds of plants produce chemicals that help to ward off the invaders.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Members of the animal kingdom have developed a variety of defense mechanisms for dealing with parasites. Although these mechanisms vary considerably, all major
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì groups of animals are capable of detecting and reacting to the presence of "foreign" cells. In fact, throughout the animal kingdom, from sponges to certain types of worms, shellfish, and all vertebrates (creatures possessing a spinal column), there is evidence that transplants of cells or fragments of tissues into an animal are accepted only if they come from genetically compatible or closely related individuals.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì The ability to distinguish between "self" and "nonself", while present in all animals, is most efficient among vertebrates, which have developed an immune system as their defense mechanism. The immune system recognizes and takes action against foreign invaders and transplanted tissues that are treated as foreign cells.

BxP^^¼8@´cforum.liuxuehome.com$WȦé/ÌìQuestion 41-50
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì The development of jazz can be seen as part of the larger continuum of American popular music, especially dance music. In the twenties, jazz became the hottest new thing in dance music, much as ragtime had at the turn of the century, and as would rhythm and blues in the fifties, rock in the fifties, and disco in the seventies.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì But two characteristics distinguish jazz from other dance music. The first is improvisation, the changing of a musical phrase according to the player s inspiration. Like all artists, jazz musicians strive for an individual style, and the improvise or paraphrased is a jazz musician s main opportunity to display his or her individuality. In early jazz, musicians often improvised melodies collectively, thus creating a kind of polyphony. There was little soloing as such, although some New Orleans players, particularly cornet player Buddy Bolden, achieved local fame for their ability to improvise a solo. Later the idea of the chorus-long or multichorus solo took hold. Louis Armstrong s instrumental brilliance, demonstrated through extended solos, was a major influence in this development.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì Even in the early twenties, however, some jazz bands had featured soloists. Similarly, show orchestras and carnival bands often included one or two such "get-off" musicians. Unimproved, completely structured jazz does exist, but the ability of the best jazz musicians to create music of great cohesion and beauty during performance has been a hallmark of the music and its major source of inspiration and change.
BxP^^¼8@´cforum.liuxuehome.com$WȦé/Ìì The second distinguishing characteristic of jazz is a rhythmic drive that was initially called "hot" and later "swing". In playing hot , a musician consciously departs from strict meter to create a relaxed sense of phrasing that also emphasizes the underlying rhythms.("Rough" tone and use of moderate vibrato also contributed to a hot sound .) Not all jazz is hot, however, many early bands played unadorned published arrangements of popular songs. Still, the proclivity to play hot distinguished the jazz musician from other instrumentalists.
