16、ction A 26 Contrary to popular belief, older people generally do not want to live with their children. Moreover, most adult children【 C1】 _every bit as much care and support to their aging parents as was the case in the “good old days“ , and most older people do not feel【 C2】 _. About 80% of people

17、65 years and older have living children, and about 90% of them have【 C3】 _contact with their children. About 75% of elderly parents who dont go to nursing homes live within 30 minutes of at least one of their children. However,【 C4】 _having contact with children does not guarantee happiness in old a

18、ge. In fact, some research has found that people who are most involved with their families have the lowest spirits. This research may be【 C5】 _, however, as ill health often makes older people more【 C6】 _and thereby increases contact with family members. So it is more likely that poor health, not ju

If parents and children share interests and values and agree on childrearing practices and religious【 C

22、g Down Civilization? A)For many years I have studied global agricultural, population, environmental and economic trends and their interactions. The combined effects of those trends and the political tensions they generate point to the breakdown of governments and societies. Yet I, too, have resisted

23、 the idea that food shortages could bring down not only individual governments but also our global civilization. B)I can no longer ignore that risk. Our continuing failure to deal with the environmental declines that are undermining the world food economy forces me to conclude that such a collapse i

24、s possible. C)As demand for food rises faster than supplies are growing, the resulting food-price inflation puts severe stress on the governments of many countries. Unable to buy grain or grow their own, hungry people take to the streets. Indeed, even before the steep climb in grain prices in 2008,

25、the number of failing states was expanding. If the food situation continues to worsen, entire nations will break down at an ever increasing rate. In the 20th century the main threat to international security was superpower conflict: today it is failing states. D)States fail when national governments

26、 can no longer provide personal security, food security and basic social services such as education and health care. When governments lose their control on power, law and order begin to disintegrate. After a point, countries can become so dangerous that food relief workers are no longer safe and the

27、ir programs are halted. Failing states are of international concern because they are a source of terrorists, drugs, weapons and refugees(难民 ), threatening political stability everywhere. E)The surge in world grain prices in 2007 and 2008 and the threat they pose to food security has a different, mor

28、e troubling quality than the increases of the past. During the second half of the 20th century, grain prices rose dramatically several times. In 1972, for instance, the Soviets, recognizing their poor harvest early, quietly cornered the world wheat market. As a result, wheat prices elsewhere more th

29、an doubled, pulling rice and corn prices up with them. But this and other price shocks were event-driven drought in the Soviet Union, crop-shrinking heat in the U. S. Corn Belt. And the rises were short-lived: prices typically returned to normal with the next harvest. F)In contrast, the recent surge

30、 in world grain prices is trend-driven, making it unlikely to reverse without a reversal in the trends themselves. On the demand side, those trends include the ongoing addition of more than 70 million people a year, a growing number of people wanting to move up the food chain to consume highly grain

31、-intensive meat products, and the massive diversion(转向 )of U. S. grain to the production of bio-fuel. G)As incomes rise among low-income consumers, the potential for further grain consumption is huge. But that potential pales beside the never-ending demand for crop-based fuels. A fourth of this year

32、s U. S. grain harvest will go to fuel cars. H)What about supply? The three environmental trends the shortage of fresh water, the loss of topsoil and the rising temperatures are making it increasingly hard to expand the worlds grain supply fast enough to keep up with demand. Of all those trends, howe

33、ver, the spread of water shortages poses the most immediate threat. The biggest challenge here is irrigation, which consumes 70% of the worlds fresh water. Millions of irrigation wells in many countries are now pumping water out of underground sources faster than rainfall can refill them. The result

34、 is falling water tables(地下水位 )in countries with half the worlds people, including the three big grain producers China, India and the U. S. I)As water tables have fallen and irrigation wells have gone dry, Chinas wheat crop, the worlds largest, has declined by 8% since it peaked at 123 million tons

35、in 1997. But water shortages are even more worrying in India. Millions of irrigation wells have significantly lowered water tables in almost every state. J)As the worlds food security falls to pieces, individual countries acting in their own self-interest are actually worsening the troubles of many.

36、 The trend began in 2007, when leading wheat-exporting countries such as Russia and Argentina limited or banned their exports, in hopes of increasing local food supplies and thereby bringing down domestic food prices. Vietnam banned its exports for several months for the same reason. Such moves may

37、eliminate the fears of those living in the exporting countries, but they are creating panic in importing countries that must rely on what is then left for export. K)In response to those restrictions, grain-importing countries are trying to nail down long-term trade agreements that would lock up futu

38、re grain supplies. Food-import anxiety is even leading to new efforts by food-importing countries to buy or lease farmland in other countries. In spite of such temporary measures, soaring food prices and spreading hunger in many other countries are beginning to break down the social order. L)Since t

39、he current world food shortage is trend-driven, the environmental trends that cause it must be reversed. We must cut carbon emissions by 80% from their 2006 levels by 2020, stabilize the worlds population at eight billion by 2040, completely remove poverty, and restore forests and soils. There is no

40、thing new about the four objectives. Indeed, we have made substantial progress in some parts of the world on at least one of these the distribution of family-planning services and the associated shift to smaller families. M)For many in the development community, the four objectives were seen as posi

41、tive, promoting development as long as they did not cost too much. Others saw them as politically correct and morally appropriate. Now a third and far more significant motivation presents itself: meeting these goals may be necessary to prevent the collapse of our civilization. Yet the cost we projec

42、t for saving civilization would amount to less than $200 billion a year, 1/6 of current global military spending. In effect, our plan is the new security budget. 37 The more recent steep climb in grain prices partly results from the fact that more and more people want to consume meat products. 38 So

43、cial order is breaking down in many countries because of food shortages. 39 Rather than superpower conflict, countries unable to cope with food shortages now constitute the main threat to world security. 40 Some parts of the world have seen successful implementation of family planning. 41 The author

44、 has come to agree that food shortages could ultimately lead to the collapse of world civilization. 42 Increasing water shortages prove to be the biggest obstacle to boosting the worlds grain production. 43 The cost for saving our civilization would be considerably less than the worlds current milit

45、ary spending. 44 To lower domestic food prices, some countries limited or stopped their grain exports. 45 Environmental problems must be solved to ease the current global food shortage. 46 A quarter of this years American grain harvest will be used to produce bio-fuel for cars. Section C 46 Declinin

46、g mental function is often seen as a problem of old age, but certain aspects of brain function actually begin their decline in young adulthood, a new study suggests. The study, which followed more than 2,000 healthy adults between the ages of 18 and 60, found that certain mental functions including

47、measures of abstract reasoning, mental speed and puzzle-solving started to dull as early as age 27. Dips in memory, meanwhile, generally became apparent around age 37. On the other hand, indicators of a persons accumulated knowledge like performance on tests of vocabulary and general knowledge kept

48、improving with age, according to findings published in the journal Neurobiology of Aging. The results do not mean that young adults need to start worrying about their memories. Most peoples minds function at a high level even in their later years, according to researcher Timothy Salthouse. “These pa

49、tterns suggest that some types of mental flexibility decrease relatively early in adulthood, but that the amount of knowledge one has, and the effectiveness of integrating it with ones abilities, may increase throughout all of adulthood if there are no diseases,“ Salthouse said in a news release. The study included healthy, educated adults who took standard tests of memory, reasoning and perception at the outset and at some point over the next seven years. The tests are designed to detect subtle(细微
