cet4考试答案 cet4考试答案 01.6 More people die of tuberculosis (结核病) than of any other disease caused by a single agent. This has probably been the case in quite a while. During the early stages of S1. the industrial revolution, perhaps one in every seventh S2. deaths in Europes crowded cities were caused by the S3. disease. From now on, though, western eyes, missing the S4. global picture, saw the trouble going into decline. With oasional breaks for war, the rates of death and infection in the Europe and America dropped steadily S5. through the 19th and 20th centuries. In the 1950s, the introduction of antibiotics (抗菌素) strengthened the trend in rich countries, and the antibiotics were allowed to be imported to poor countries. Medical researchers S6. declared victory and withdrew. They are wrong. In the mid-1980s the frequency of S7. infections and deaths started to pick up again around the world. Where tuberculosis vanished, it came back; in S8. many places where it had never been away, it grew better. S9. The World Health Organization estimates that 1.7 billion people (a third of the earths population) suffer from tuberculosis. Even when the infection rate was falling, population growth kept the number of clinical cases more or leconstantly at 8 million a year. Around S10. 3 million of those people died, nearly all of them in poor countries. 02.1 Sporting activities are essentially modified forms of hunting behavior. Viewing biologically, the modern footballer is revealed as a S1. member of a disguised hunting pack. His killing weapon has turned into a harmlefootball and his prey into a goal-mouth. If his aim is inaurate S2. and he scores a goal, enjoys the hunters triumph of killing his prey. S3. To understand how this transformation has taken place we must briefly look up at our ancient ancestors. They spent over a S4. million year evolving as co-operative hunters. Their very survival S5. depended on suein the hunting-field. Under this pressure their whole way of life, even if their bodies, became radically changed. They became S6. chasers, runners, jumpers, aimers, throwers and prey-killers. They co-operate as skillful male-group attackers. S7. Then, about ten thousand years ago, when this immensely long S8. formative period of hunting for food, they became farmers. Their improved intelligence, so vital to their old hunting life, were put to a new S9. use-that of penning ( 把关在圈中), controlling and domesticating their prey. The food was there on the farms, awaiting their needs. The risks and uncertainties of farming were no longer essential for survival. S10. 02.6 A great many cities are experiencing difficulties which are nothing new in the history of cities, except in their scale. Some cities have lost their original purpose and have not found new one. And any large or rich city is going to attract poor S1. immigrants, who flood in, filling with hopes of prosperity S2. which are then often disappointing. There are backward towns on the edge of Bombay or Brasilia, just as though there were S3. on the edge of seventeenth-century London or early nine- teenth-century Paris. This is new is the scale. Descriptions S4. written by eighteenth-century travelers of the poor of Mexico City, and the enormous contrasts that was to be found there, S5. are very dissimilar to descriptions of Mexico City today - the S6. poor can still be numbered in millions. The whole monstrous growth rests on economic prosperity, but behind it lies two myths: the myth of the city as a S7. promised land, that attracts immigrants from rural poverty S8. and brings it flooding into city centers, and the myth of the S9. country as a Garden of Eden, which, a few generations late, S10. sends them flooding out again to the suburbs. 03.6 The Seattle Times Company is one newspa-pe-r firm that has recognized the need for change and done something about it. In the newspa-pe-r industry, pa-pe-rs must reflect the diversity of the munities to which they provide information. It must reflect that diversity with their news coverage or risk S1. losing their readers interest and their advertisers support. Operating within Seattle, which has 20 percents racial S2. minorities, the pa-pe-r has put into place policies and procedures for hiring and maintain a diverse workforce. The S3. underlying reason for the change is that for information to be fair, appropriate, and subjective, it should be reported by the S4. same kind of population that reads it. A diversity mittee posed of reporters, editors, and photographers meets regularly to value the Seattle Times S5. content and to educate the rest of the newsroom staff about diversity issues. In an addition, the pa-pe-r instituted a content S6. audit(审查) that evaluates the frequency and manner of representation of woman and people of co
