Moreover, most adult children 26 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 27 .About 80% of people 65years and older have living children, and about 90% of them have 28 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, 29 having contact with children does not guarantee happiness in old age. In fact, some research has found that people who are most involved with their families have the lowest spirits. This research may be 30 , however, as ill health often makes older people more 31 and thereby increases contact with family members. So it is more likely that poor health, not just family involvement, 32 spirits.Increasingly, researchers have begun to look at the quality of relationships, rather than at the frequency of contact, between the elderly and their children. If parents and children share interests and values and agree on childrearing practices and religious 33 , they are likely to enjoy each others company. Disagreements on such matters can 34 cause problems. If parents are agreed by their daughters divorce, dislike her new husband, and disapprove of how she is raising their grandchildren, 35 are that they are not going to enjoy her visits. A) abandoned                   E)commitment I)frequent M)provide  B)advanced                    F)dampens J)fulfillment N)understandably C)biased                       G)dependent K)grant O)unrealistically D)chances                      H)distant L)merely                  Section BDirections: In this section, you are going to read a passage with ten statements attached to it. Each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.Could Food Shortages Bring 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 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 is 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 2023, 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 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 their 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 2023 and 2023and the threat they pose to food securityhas a different, more 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 than doubled, pulling rice and corn prices up with them. But this and other price shocks were event-drivendrought 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 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-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 years U.S. grain harvest will go to fuel cars.H What about supply? The three environmental trendsthe shortage of fresh water, the loss of topsoil and the rising temperaturesare making it increasingly hard to expand the worlds grain supply fast enough to keep up with demand. Of all those trends, however, the spread of water shortages poses the most immediate threat. The biggest challenge here is irrigation, which consumes 70% 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 is falling water tables(地下水位) in countries with half the worlds people, including the three big grain producersChina, 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 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. The trend began in 2023, 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 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
