7、ergeD.emphasizeInterferon For several years, scientists have been testing a substance called interferon (干扰素),a potential wonder drug that is proving to be effective in treating a variety of ailments, including virus infections, bacteria infections, and tumors. To date, the new drug has provoked no

8、negative reaction of sufficient significance to discourage its use. But in spite of its success, last year only one gram was produced in the entire world. The reason for the scarcity lies in the structure of interferon. A species specific protein, the interferon produced from one animal species cann

9、ot be used in treating another animal species. In other words, to treat human beings, only interferon produced by human beings may be used. The drug is produced by infecting white blood cells with a virus. Fortunately, it is so potent that the amount given each patient per injection is very small. U

10、nlike antibiotics(抗菌素), interferon does not attack germs directly. Instead, it makes unaffected cells resistant to infection, and prevents the multiplication of viruses within cells. As you might conclude, one of the most dramatic uses of interferon has been in the treatment of cancer. Dr. Hans Stra

11、nder, research physician at Swedens famous Karolinska Institute, has treated more than one hundred cancer patients with the new drug. Among a group of selected patients who had undergone surgical procedures for advanced cancer, half were given conventional treatments and the other half were given in

12、terferon. The survival rate over a three-year period was 70 percent among those who were treated with interferon as compared with only 10 to 30 percent among those who had received the conventional treatments. In the United States, a large-scale project supported by the American Cancer Society is no

13、w underway. If the experiment is successful, interferon could become one of the greatest medical discoveries of our time. （分数：-0.98）(1).Antibiotics kill germs by attacking them directly, while interferon does not.（分数：-0.14）A.RightB.WrongC.Not Mentioned(2).The effect interferon has on infection is th

You may be surprised to learn that there are about

17、ninety-nine thousand separate villages and towns. Some are big places like Mexico City, some are single houses deep in the jungles or upon the mountain-tops. The men working with our programme say that most of these localities lie within districts warm enough for the malaria-carrying mosquitoes to l

18、ive in and spread the disease. That means that we must plan to spray the walls of nearly three million house once or twice a year for five years.“ 2. “We have studied everything very carefully“ , the officer continued. “Our advance guards have drawn maps of some forty thousand parts of the country f

19、or use by the spray teams. Each house in the malaria districts has been given a special number. The United Nations has given us cars and trucks to carry the spray teams and their tools, but many of the houses to be sprayed are too difficult to reach by car. Half of our spray teams go on horseback or

20、 by boat.“ 3. “The malaria programme has been popular with the Mexican people. Everyone wants to help. The navy has offered us the services of ships. The Defence Department is helping us plan the movement of men and supplies. The Ministry of Education has printed sheets in Spanish and the more widel

21、y spoken Indian languages to explain how malaria is spread and why spraying helps. Doctors have spoken in the churches of many communities to explain the programme.“ 4. Resistance is a problem. It was in the United States that such resistance to sprays was first proved. Since then many other insects

22、 have developed resistance to poisons. Take the case of the housefly and D.D.T. At first D.D.T. killed them off. For a time flies died quickly. Then no more. Now D.D.T. wont hurt a fly. 5. What worries the health workers is the danger that mosquitoes may become resistant. Already resistance to some

23、of the sprays has appeared in parts of the world, although no insect is yet resistant to all of the sprays. A. What worries us? B. What we have done? C. Whats our job? D. More and more people joined us. E. It will be a hard work. F. Whats the problem? （分数：-1.04）(1).Paragraph 2（分数：-0.13）A.B.C.D.(2).P

26、 likely to crash from mishandling the aircraft. These are the results of a study by researchers at the Johns Hopkins University Bloomberg School of Public Health. The study identifies the differences between male and female pilots in terms of circumstances of the crash and the type of pilots error i

27、nvolved. “Crashes of general aviation aircraft account for 85 percent of all aviation deaths in the United States. The crash rate for male pilots, as for motor vehicle drivers, exceeds that of crashes of female pilots,“ explains Susan P. Baker, MPH, professor of health policy and management at the B

28、loomberg School of Public Health. “Because pilot youth and inexperience are established, contributors to aviation crashes, we focused on only mature pilots, to determine the gender differences in the reasons for the crash.“ The researchers extracted data for this study from a large research project

29、on pilot aging and flight safety. The data were gathered from general aviation crashes of airplanes and helicopters between 1983 and 1997, involving 144 female pilots and 267 male pilots aged 40-63. Female pilots were matched with male pilots in a 1:2 ratio, by age, classes of medical and pilot cert

30、ificates, state or area of crash, and year of crash. Then the circumstances of the crashes and the pilot error involved were categorized and coded without knowledge of pilot gender. The researchers found that loss of control on landing or takeoff was the most common circumstance for both sexes, lead

31、ing to 59 percent of female pilots crashes and 36 percent of males. Experiencing mechanical failure, running out of fuel, and landing the plane with the landing gear up were among the factors more likely with males, while stalling was more likely with females. The majority of the crashes 95 percent

32、for females and 88 percent for males involved at least one type of pilot error. Mishandling aircraft kinetics was the most common error for both sexes, but was more common among females(accounting for 81 percent of the crashes) than males (accounting for 48 percent). Males, however, appeared more li

33、kely to be guilty of poor decision-making, risk-taking, and inattentiveness, examples of which include misjudging weather and visibility or flying an aircraft with a known defect. Females, though more likely to mishandle or lose control of the aircraft, were generally more careful than their male co

40、o make more errors in decision-making.Suburb If “suburb“ is meant an urban margin that grows more rapidly than its already developed interior, the process of suburbanization began during the emergence of the industrial city, in the second quarter of the nineteenth century. Before that period the cit

41、y was a small, highly compact cluster in which people moved about on foot, and goods were conveyed by horse and cart. But the early factories, built in the 1830s and 1840s, were located along waterways and near railheads at the edges of cities, and housing was needed for the thousands of people draw

42、n by the prospect of employment. In time, the factories were surrounded by proliferating mill towns of apartments and row houses around the older, main cities. As a defence against this encroachment, and to enlarge their tax bases, the cities appropriated their industrial neighbors. In 1854 for exam

43、ple, the city of Philadelphia annexed most of Philadelphia County. Similar municipal maneuvers took place in Chicago and in New York. Indeed, most great cities of the United States achieved such status only by incorporating the communities along their borders. With the acceleration of industrial gro

44、wth come acute, urban crowding and accompanying social stress-conditions began to approach disastrous proportions when, in 1888, the first commercially successful electric traction line was developed. Within a few years the horse-drawn trolleys were retired and electric streetcar networks crisscross

45、ed and connected every major urban area, fostering a wave of suburbanization that transformed the compact industrial city into a dispersed metropolis. This first phase of mass-scale suburbanization was reinforced by the simultaneous emergence of the urban middle class, whose desires for homeownershi

46、p in neighborhoods far from the aging inner city were satisfied by the developing of single-family housing tracts. （分数：-1.00）(1).Which of the following is the best title for the text?（分数：-0.20）A.The Growth of Philadelphia.B.The Origin of the Suburb.C.The Development of City Transportation.D.The Rise
