26、ople in the world will be over 60 years old, and more than two-thirds of them will be living in developing countries. In the early 1950s, average life expectancy at birth was 47 years worldwide. In 1995 it was more than 65 years, and in several countries it was almost 80. Change of this magnitude am
27、ounts to a revolution in both demographic and cultural terms. It has been brought about partly by socioeconomic factors, such as better nutrition and living conditions, and partly by improvements in health care. Not only do we have drugs and treatments to cure diseases that in the past led to premat
28、ure death, we also have vaccines to prevent many of these diseases, and in some cases even to eradicate them. Furthermore, a larger proportion of the world s population has ready access to effective medicine.If the main public health challenge of this century has been survival, that of the next will
29、 be quality of life. With the steadily rising number of children who reach adulthood and adults who reach old age, the most pressing concern becomes that of ensuring that all of them enjoy the highest attainable level of well-being.To help promote a global response to this major societal concern. WH
30、O launched a new programme on ageing and health in 1995. Its perspectives and activities are described in this issue of World Health, together with some of the ways in which society is responding to this new phenomenon of a growing elderly population. Health is generally felt to be of paramount impo
31、rtance for the quality of life, especially in old age, when physiological and other difficulties tend to accumulate and the end of life approaches. There are many more ways of protecting and improving health than people generally realize, and these articles provide valuable insights into the possibi
32、lities that exist.51 The best title for this passage is_.（A）Public Health a Hot Topic（B） The World s Population a Knotty Problem（C） The Most Pressing Concern Healthy Old Age（D）Good Health Services and Good Health52 According to the passage, the change of average life expectancy at birth was due to_.
33、（A）a revolution in both demography and culture（B） premature and natural death（C） socioeconomic factors and improvements in health care（D）both A and B53 Which of the following statements is NOT true according to the passage?（A）Quality of life will be seriously taken into account in the 21st Century.（
34、B） All the people, including the elderly, are now able to enjoy the highest attainable level of well-being.（C） A large proportion of the worlds population has benefited from effective medicine.（D）With the development of science and technology, man s capacity to prevent and cure diseases has striking
35、ly been enhanced.54 It can be inferred from the passage that_.（A）more attention will be paid to drugs and vaccines in preventing diseases leading to premature death（B） effective medicine will be available for most people in developing countries in the 21 st Century（C） the issue of ageing and health
36、was discussed in World Health in 1995 in order to help old people live a quality life（D）the 21st Century will witness a pressing task of healthy old age throughout the world, in developing countries in particular55 In the passage, the author insists that_.（A）average life expectancy is getting longer
37、 and longer worldwide（B） people are enjoying longevity because of better nutrition and better living condition（C） the quality of life will be the most important challenge in the next century（D）a major societal concern is how to grow old55 Dr. Beatrice Hahn of the University of Alabama at Birmingham
38、announced that she d learned the origins of HIV-1, the virus responsible for 99 percent of the world s 33million AIDS cases. Hahn and her colleagues were able to trace it specifically to a subspecies of chimpanzee called Pan troglodytes.Chimps are not the only primates that carry viruses related to
39、HIV. Earlier this decade scientists linked HIV-2 to a monkey called the sooty mangabey. Mandrills and African green monkeys carry still other simian immuno-deficiency viruses(SIVs). The closest links to HIV-1 seemed to be three viral samples isolated in chimpanzees. But one of the three was so diver
40、gent from the other two that scientists doubted they were HIV-1 s immediate ancestors. To solve this puzzle, Hahn and her international team first had to fit the human and simian viruses into genetic “family trees“ that accounted for their similarities and differences. They next had to show that the
41、 chimps were in the same region where AIDS got its start in humans. In fact, the chimp subspecies lives in West Central Africa, the region where HIV-1 is thought to have originated. There was even a plausible mode of transmission from chimp to human. The animals have long been hunted for food, so bl
42、ood from the carcasses could easily have entered the hunters bodies through superficial wounds. Hahns group showed how, after jumping species on at least three occasions, chimpanzee SIV evolved into the three families of HIV-1 strains recognized today.The question is not merely of academic interest.
43、 The chimps, it seems, carry their version of the virus but do not get sick from it. In theory at least, they could reveal important clues about controlling AIDS. “Humans share 98.5 percent of their genes with chimpanzees, points out Dr Feng Gao of UAB, one of Hahn s collaborators. But just as scien
44、tists are learning the chimps value in AIDS research, this critical subpopulation is being hunted to the brink of extinction. Not only does that mean hunters may be contracting additional viral strains; it also means that mankind is losing a living data-base of AIDS information. “It s like burning a
45、 whole library of books without having read them,“ says Hahn. Given the similarity of man and chimp, it could prove a tragic loss. Who knows what other mysteries may be answered in those books.56 According to the passage, which of the following viruses is the culprit in causing AIDS?（A）HIV-2.（B） HIV
46、-1.（C） SIV.（D）Simian viruses.57 According to the passage, how could humans get the immuno-deficiency virus from the chimps?（A）Through eating the carcasses of the chimps.（B） Through blood transmission.（C） Through hunting.（D）Through living in the same region as the chimps.58 In the eyes of scientists,
47、 the chimps are of great value in AIDS research because_.（A）they are like books in a library which are worth reading（B） they never get sick（C） they could provide clues for further research on AIDS controlling（D）humans share all their genes with the chimps59 Which of the following can best describe t
48、he author s feeling toward the near extinction of that critical chimp subspecies?（A）Worried.（B） Indifferent.（C） Resigned.（D）Angry. 60 Which of the following could be the best title for this article?（A）Fatal Diseases in West Central Africa.（B） The Chimp a Possible Killer in West Central Africa.（C） Ho
49、w AIDS Began Linking HIV-1 to Chimps in West Central Africa.（D）How HIV-1 Spreads in West Central Africa.60 Among the most stressful of worries are death, illness, loss of work, money problem, marital problems and retirement. Such worries have rational basis, but we are curiously irrational in the way we pursue them. For example, fear of death is as strong among young adults as among the elderly. It is equally surprising that we are as worried
