18、ulating C. fabricating D. ponderingPart III Reading Comprehension (60%)Questions 51 to 55 are based on the following passage.When a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction and find ways to combat it. Of

19、tentimes, success is achieved, as medical science is able to isolate the parasite, germ or cell that causes the problem and finds ways to effectively kill or contain it. In the most serious of cases, in which the entire population of a region or country may be at grave risk, it is deemed necessary t

20、o protect the entire population through vaccination, so as to safeguard lives and ensure that the disease will not spread.The process of vaccination allows the patients body to develop immunity to the virus or disease so that, if it is encountered, one can fight it off naturally. To accomplish this,

21、 a small weak or dead strain of the disease is actually injected into the patient in a controlled environment, so that his bodys immune system can learn to fight the invader properly. Information on how to penetrate the diseases defenses is transmitted to all elements of the patients immune system i

22、n a process that occurs naturally, in which genetic information is passed from cell to cell. This makes sure that, should the patient later come into contact with the real problem, his body is well equipped and trained to deal with it, having already done so before.There are dangers inherent in the

23、process, however. On occasion, even the weakened version of the disease contained in the vaccine proves too much for the body to handle, resulting in the immune case of the smallpox vaccine, designed to eradicate the smallpox epidemic that nearly wiped out the entire Native American population and k

24、illed massive numbers of settlers. Approximately 1 in 10,000 people who receives the vaccine contract the smallpox disease from the vaccine itself and dies from it. Thus, if the entire population of the United States were to receive the Smallpox Vaccine today, 3000 Americans would be left dead.Fortu

25、nately, the smallpox virus was considered eradicated in the early 1970s, ending the mandatory vaccination of all babies in America In the event of a re-introduction of the disease, however, mandatory vaccinations may resume, resulting in more unexpected deaths from vaccination. The process, which is

26、 truly a blessing, may indeed hide some hidden cures.51. How do vaccines protect humans from diseases according to paragraph two?A. By passing information on how to fight the disease to the disease.B. By passing information on how to fight the disease to the immune system.C. By weakening the disease

27、 so that the immune system can defeat it.D. Introducing the disease to the body, so that survivors have already fought it.52. What does the example of the smallpox vaccine illustrate?A. The way that vaccines protect people from diseases.B. The effectiveness of vaccines in eradicating certain disease

28、s.C. The practical use of a vaccine to control an epidemic disease.D. The possible negative outcome of administering vaccines.53. The author argues that vaccinations are both a blessing and a curse because .A. saving the many would not necessarily justify the death of the few.B. some vaccines, such

29、as the smallpox vaccine, have negative side effects.C. they dont always work.D. while many lives are saved, SOME ARE ACTUALLY KILLED BY THE VACCINT.54. The best title for the passage would be .A. “The Smallpox Vaccine: An Analysis”.B. “How Vaccines Work”.C. “Vaccines: Methods and Implications”.D. “A

30、 Warning on the Negative Side Effects of Vaccines”.55. The main purpose of the passage is to .A. convince the reader that vaccines are not as safe as many think.B. educate the reader on how vaccines are used and some of their dangers.C. educate the reader on the circumstances that would necessitate

31、widespread vaccinations.D. present the method by which vaccines are used through the case of the smallpox vaccine.Passage TwoQuestions 56 to 60 are based on the following passage.Few natural dangers are more feared than avalanches. Avalanches are a familiar part of European history, Particularly in

32、the Swiss and French Alps. This is where the direction of wars has turned almost instantly because of avalanches wiping out invading armies.In North America, avalanches are limited almost entirely to the Rocky Mountains and the lower ranges to the west, the Sierra Nevadas and the Cascades. Avalanche

33、s have occurred in the mountains of New England but not with the regularity and intensity seen in the western mountains.Several methods are used in explaining and predicting avalanches. Scientists and learning about them using research methods. So many of the factors that create avalanches are hidde

34、n beneath the snows surface that predictions are still largely guesswork. Therefore, winter travelers must assume the worst of conditions when the traverse the slopes.An avalanche occurs when a given amount of snow becomes too heavy for whatever is holding it in place. It then breaks loose and slide

35、s downhill. Avalanches are divided into two general categories, loose snow and slab. A loose snow avalanche usually starts at a single point, such as a skiers track, and spreads out like a fan or a pyramid in a chain reaction. One crystal breaks another free, which multiples as the loose snow moves

36、downhill. Sometimes these avalanches stop after only a few feet. Sometimes they move thousands of tons of snow downhill in speeds up to 300 miles per hour. This creates a shock wave that can flatten parts of a forest that are not even touched by the actual avalanche.Slab avalanches are those that ha

37、ve a wide area of snow which breaks loose in a large piece. These can range in size from just a few square feel to thousands of square feet of snow. The most dangerous and common type of avalanche for skiers is the so-called “soft slab” avalanche. This type occurs most often during, or just after a

38、heavy snowfall. The snow hasnt yet had a chance to settle and adhere to the temperature, the less likely the new snow will form a bond with theexisting snow.56. What would be the best title for this passage?A. AvalanchesB. The History of AvalanchesC. Skiers BewareD. Avalanches Can Kill57. According

39、to the passage, how did avalanches affect wars?A. They hid the armies approaching the city aiding in the attack.B. They killed the armies approaching the city.C. They blocked paths into the city.D. They snowblinded the approaching armies.58. According to the passage, what must skiers assume about av

40、alanches when skiing?A. They only have to worry after a heavy snowfall.B. Avalanches only occur in the Swiss or French Alps.C. They should always expect that an avalanche will occur.D. When skiing in New England, they will never have to worry about an avalanche.59. According to the passage, when is

41、the most dangerous time for skiers?A. When the temperature is below 20 degrees F.B. Right before a snowstorm.C. During a snowstorm.D. In the winter.60. According to the passage, which factor causes an avalanche?A. The slope of the mountain.B. The size of the snowfall.C. The amount and intensity of m

42、ovement around the snowfall.D. The weight of the snow.Passage ThreeQuestions 61 to 65 are based on the following passage.Recent stories in the newspapers and magazines suggest that teaching and research contradict each other, that research plays too prominent a part in academic promotions, and that

43、teaching is badly underemphasized. There is an element of truth in these statements, but they also ignore deeper and more important relationships.Research experience is an essential element of hiring and promotion at a research university because it is the emphasis on research that distinguishes suc

44、h a university from an arts college. Some professors, however, neglect teaching for research and that presents s problem. Most research universities reward outstanding teaching, but the greatest recognition is usually given for achievements in research. Part of the reason is the difficulty of judgin

45、g teaching. A highly responsible and tough professor is usually appreciated by top students who want to be challenged but disliked by those whose records are less impressive. The mild professor gets overall ratings that are usually high, but there is a sense of disappointment on the part of the best

46、 students, exactly those for whom the system should present the greatest challenges. Thus, a university trying to promote professors primarily on the basis of teaching qualities would have to confront this confusion.As modern science moves faster, two forces are exerted on professors: one is the time needed to keep up with the profession; the other is the time needed to teach. The training of new scientists requires outstanding teaching at
