28、life has been a dream for mankind since always. With the improvement of health care, nutrition and health knowledge, we began to make dramatic efforts to reduce the effects of the forces that had traditionally shortened human existence. 10 million to 17 million people aged 65 or older made up less t

29、han 1 percent of the worlds population in 1900. Survival rates began to climb for infants, children and women of childbearing age, gradually lifting humanitys average life span. By 2000, 606 million were aged 60 or older, and they made up almost 10 percent of the worlds population. According to the

30、United Nations report World Population Prospects, by 2050 that group could swell to 1.9 billion and constitute one fifth of the worlds projected population. But it is not all about to live a longer life. And it would not be such a good idea to live your last years in illness and pain. In fact, it wo

31、uld turn into a torture. No, we want to live better, more youthful days while were living longer. Diet, exercise and a lucky draw from the gene pool can take us only so far, however. Thats where science comes in. As medicine tries to find out the means to extend life, culture and its institutions wi

32、ll have to deal with the consequences of success. Age-entitlement programs, such as Social Security, were formed when younger workers far outnumbered retirees, who drew benefits for only a few years; what reforms will longer lives require? When savings are used up by parents who may be retired for u

33、p to one third of their lives? And, equally important, how will we make our extra years emotionally rewarding and rich? Medicine will continue to advance, and, we expect, society and policymakers will have to learn to adapt to the challenges of longevity-both providing it and providing for it-that a

34、wait us all. 46 Which one of the following is not mentioned in paragraph 1 as the motivation for people to try to live a longer life? （ A） We now have better equipment in hospitals. （ B） We are now better informed about how to live a healthy life. （ C） We know what kind of food would do us good, and

36、 medical care. （ C） More children were born so that the old can be better taken care of, （ D） Less newly-born children and the mother bearing them die. 48 What does the word “projected“ (Para. 2 Line 6) mean in the context? （ A） A piece of planned work or an activity. （ B） The calculated amount or n

37、umber expected in the future. （ C） To throw or direct something forwards, with force. （ D） A study of a particular subject done over a period of time. 49 What is the main idea of paragraph 4? （ A） Maybe individuals living longer would not be such a good thing for our society as a whole. （ B） It is t

38、he quality of life, instead of its length, that truly matters. （ C） We have some related issues to worry about along with the citizens longevity. （ D） The current welfare system is not ready yet to support such a large old-age population. 50 Which one of the following is the most suitable title for

39、this passage? （ A） Longevity: Ought to be provided and provided for. （ B） Old age: A few emotionally rewarding extra years. （ C） How to manage an aging population. （ D） To live longer: A dream that has come true. 51 Overweight has become a problem people all around the world face, and it does not lo

40、ok like it will be solved in the near future regardless of the various efforts from all walks of life. And for those who have a heavier body than they are supposed to, one advice is given repeatedly: eat less and exercise more. This has long been the suggestion for getting rid of those extra pounds.

41、 But now it seems that all the hard work may have been in vain. Scientists say there are ten other reasons why people just keep getting bigger. Scientists claim that sleeping habits, central heating, medicines and even some pollutants can play a role in weight gain. Lack of sleep could be partly to

42、blame. In recent years, the average nights sleep has dropped from nine hours to just seven. Sleep lack changes levels of the hormones that regulate food intake and body fat and increase hunger and appetite. If it is too hot or too cold, we burn calories to cool down or heat up. But if the temperatur

43、e is just right, the calories may be turned into body fat instead. Those who take medicines to control their blood pressure can often put on more weight. Similarly, studies have shown that going on the Pill can add to a womans weight. Mother Nature may also be to blame, with our body shape being par

44、tly determined by our parents. The overweight are also more likely to be associated with partners of a similar size, and their children are more likely to be overweight. The scientists from Yale, Cornell and Johns Hopkins published their analysis of these findings last week. Their reasoning goes lik

45、e this: 1. Sleep-Too little increases appetite. 2. Medicine-Many modern medicines lead to us putting on weight. 3. Mothers age-Older women are more likely to have obese children. 4. Giving up smoking-Nicotine suppresses the appetite. 5. Getting older-Weight tends to increase with age. 51 What does t

46、he author think of the advice “eat less and exercise more“? （ A） It may not be a solution for all who face this problem since the reasons for peoples getting fat varies. （ B） There are various other ways to achieve the goal of weight-loss and this is not the best one. （ C） Exercise is something you

47、will never get your returns and your efforts will be in vain. （ D） It has been talked about for too long a time that a newer alternative is needed. 52 Which factor is mentioned in paragraph 2? （ A） Too much sleep may increase ones weight. （ B） Lack of sleep may be one of the reasons causing the over

48、weight problem. （ C） 9 hours of sleep is perfect for people to stay slim. （ D） Less than 7 hours of sleep will increase the danger of gaining extra pounds. 53 What should be blamed according to the analysis in paragraph 3? （ A） Medicines and health care. （ B） Sleeping habits. （ C） Central heating sy

49、stem in most workplace. （ D） Lack of exercise. 54 According to paragraph 4, apart from medicines, what is the other factor that causes overweight? （ A） The living habits of one family. （ B） The genes we inherit from our parents. （ C） The marriage partner we choose. （ D） The inhabitation of people with similar size living together. 55 Which one of the following is NOT a correct cause-effect analysis? （ A） Too little sleep may cause us to e
