17、 word. Write your answers on ANSWER SHEET 1. 31 Centuries ago, Western culture lost its focus (31) the interconnectedness between the body and the mind (32) spirit, and how each has the power to affect the (33). Cultivating a love of movement can help you get beyond the concept of physical fitness a

Whether you choose yoga or another (35) of movement for exercise, remember that our bodies are (36) to move to feel good. So (37) you incorporate regular activity in your life, you are moving cl

23、ions: Read the following texts and answer the questions which accompany them by choosing A, B, C or D. Mark your answers on ANSWER SHEET 1. 51 Allergies cause heaps of trouble. Some people suffer the nuisance of seasonal hay fever, snuffling and sneezing as pollen flows through the air. Others react

24、 to materials such as metals, developing unpleasant rashes at their very touch. And some sorry souls go into shock at the mere presence of certain foods, particularly peanuts and shellfish. The cause in each case is an oversensitive immune system that is reacting to harmless materials as well as to

25、the pathogens it is supposed to be fighting. This creates annoying and sometimes life-threatening symptoms. Chronically over-reactive immune systems may not, though, be an entirely bad thing. Another role played by the immune system is to destroy malignant tumours before they take hold and work carr

26、ied out recently by Annette Wigertz of the Karolinska Institute, in Stockholm, and her colleagues suggests that the immune systems of those with allergies may be particularly good at this. However, in a nice example of the way that one set of data is sometimes capable of divergent indeed, opposite i

27、nterpretations, she may instead have discovered a clue about how cancers shut down immune systems in order that they themselves may prosper. This Manichean finding came after Dr. Wigertz and her team interviewed 1,527 people with gliomas (a type of brain turnout) in Denmark, Finland, Norway, Sweden

28、and the south-east of England. The researchers asked the patients in question whether they had a history of allergies, and then compared the results with those for 3,309 otherwise similar individuals who did not have brain tumours. As Dr. Wigertz reports in the American Journal of Epidemiology, the

29、tumour-free were, indeed, more likely to suffer from allergies. The presence of an allergy was associated with a 30% reduction in the likelihood of having a glioma. This was not all that surprising. Previous research had detected similar inverse correlations between allergies and brain tumours, sugg

30、esting that a welcome side effect of allergy was resistance to cancer. But this new study went further. It looked carefully at the time in the patients lives when their allergies were active, and it found that this timing was crucial. Dr. Wigertz noted that the absence of allergy was correlated with

31、 the time when a glioma first formed. That was true even in people who had previously had allergies which had then cleared up. Awkwardly, this result is open to two rather different interpretations. The optimistic explanation is that the hyperactive immune system associated with allergy does, indeed

32、, protect against turnouts. In that case, the coincidence was caused by turnouts taking advantage, as it were, of the reduced immune surveillance that accompanied the disappearance of the allergy. The sinister interpretation is that tumours are doing something as they grow that suppresses the immune

33、 system and thus allergic reactions. Either way, turnout and lack of allergy coincide. And either way, something interesting is going on. But Dr. Wigertzs result illustrates the perils of leaping to conclusions on the basis of incomplete data. 51 Which of the following is a disease? （ A） Nuisance. （

34、 B） Pollen. （ C） Rash. （ D） Shock. 52 The second paragraph suggests that what has been discovered about immune system can be used_. （ A） to strengthen immune systems capacity to fight pathogens. （ B） to create immune system with allergies. （ C） to interpretate the data contained in immune system. （

35、D） to find out how cancers fight immune system. 53 Which of the following statements about Dr. Wigertzs study is TRUE? （ A） the interviewees of the study are those who are suffering allergies. （ B） the team examined 1, 527 cases. （ C） there is a negative correlation between allergies and brain tumor

36、s. （ D） 30% of those who suffer from glioma also suffer from allergies. 54 The new study surpasses the previous one in that_. （ A） it identified side effects of allergies. （ B） it established that allergy can be cancer-resistant. （ C） it specified the time when allergy is active in human body. （ D）

37、it found more about how allergy is correlated with tumor. 55 Dr. Wigertzs finding suggests_. （ A） that allergic reactions can be either good or bad. （ B） that its still early to draw any conclusion. （ C） that allergies may suppress the growth of tumor. （ D） that they are not quite sure about the con

38、sequence of their study. 56 The award of the Nobel science prizes often brings blinking into the limelight people who have laboured unknown to the wider world. Seldom, though, is there such a compelling human story to go with the intellectual one as that of Mario Capecchi, one of the winners of the

39、medicine prize. His father was an airman who was killed in North Africa during the Second World War. His mother was sent to Dachau concentration camp. He survived more than three years as a street kid in Italy before migrating to America after the war was over and yet he ended up helping to develop

40、one of the most important tools of modern biology, the knockout mouse. It is not quite a rags-to-riches story. In truth, his family was well connected in a bohemian sort of way, and his mother (the daughter of a painter and an archaeologist) was an American. But it does make great copy for reporters

41、 covering an event that has the true characteristics of celebrity. For, like many of those who populate the pages of celebrity magazines, the Nobel prizewinners are most famous for being famous. In most years, the prize-winning work itself makes dull copy. This year, however, the prize committees of

42、 the Karolinska Institute (Swedens main medical school) and the countrys Royal Academy of Science seem to have taken some lessons in public relations. Not only have they picked a researcher with an interesting back-story, but they have also cunningly disguised a deserved but possibly contentious awa

43、rd by bundling it in with something else. On top of that, one of the topics chosen for a prize has an obvious resonance with the public. The bundling was done in the medicine prize. Dr. Capecchi shares this with Oliver Smithies, another immigrant to America (he was born in Britain) and Sir Martin Ev

44、ans, a Briton who stayed at home. Working independently, these three men provided the parts that, when put together, enable the elimination of one gene at a time from the genetic make-up of a mouse. That is of medical significance because it allows mouse “models“ of human genetic diseases to be made

45、 and most diseases have at least some genetic component. The physics prize, by contrast, has nothing but feel-good about it. It is for giant magnetoresistance the basis of modern computer hard-drive memories. The phenomenon itself was discovered, independently, by Albert Fert, a Frenchman, and Peter

46、 Grunberg, a German, in 1988. Its significance is that a small magnetic field can induce a large change in the electrical conductivity of an appropriately designed material. The result has been that the amount of data computers can store has grown even faster than their ability to process it. 56 Mar

47、io Capecchi_. （ A） was born in Italy. （ B） was born into a poor family. （ C） joined his family in America after the war. （ D） had tough time during his childhood because of the war. 57 Mario Capecchi was well reported because of_. （ A） his life story. （ B） his achievement in biology. （ C） his study

48、field. （ D） his unusual intelligence. 58 The prize committee improves their work by_. （ A） setting up more rigorous standards. （ B） paying more attention to public response. （ C） finding more interesting topics in science. （ D） learning lessons from scientific world. 59 The Nobel prizewinners in med

49、icine_. （ A） based their studies in America. （ B） brought their findings together to form a comprehensive solution to genetic diseases. （ C） experimented on mouse modeling human diseases. （ D） worked out things that are highly related to each other. 60 The physics prize_. （ A） awarded a finding which turned out to be insignificant. （ B） went to two scholars who worked with computer. （ C） had something in common with the medicine prize. （ D） substantially improved the efficiency of computing. 61
