Task 2
Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45.
A new report of the United Nations shows that, if the present growth rate of 2 percent per year continues, today's world population of 5.1 billion will hit 6.4 billion by the year 2000. What's more, the great part of the growth—9 of every 10 people added to the earth's population—will be in the poor and undeveloped countries. These are the nations where providing enough food for billions of people already is proving to be a headache problem.
By the year 2000, today's "have not" nations will have a total population of 5 billion people, nearly four fifths of the world's population.
Food isn't the only problem that such a population explosion presents. The more people there are and the worse their living conditions, the greater grow the possibility of all kinds of social problems.
In 1830, world population reached 1 billion. It took only 100 more years to add another billion to world population; just 30 more to add a third billion. And it took just 15 more years to reach the 4 billion mark in 1975. Actually, the world's birth rate is falling. But so is death rate, as medical advances have made it possible for man to live longer than before. Such advances have also reduced baby death rate. Unless population growth is reduced, the world population may reach 12 billion in a century. Is the earth capable of providing a good life for so large a population？
A population explosion will lead to ______.
A．a lot of social problems
B．medical advances
C．a decrease in food production
D．a worse life in every nation with 3 billion

听力原文： The twentieth century has brought with it many advances. (32) With those advances, human lives have changed dramatically. In some ways life is worse, but mostly it is better. Changes in food preparation methods, for example, have improved our lives greatly.
Food preparation today allows for more variety. With refrigerators and freezers, we can preserve a lot of different foods in our homes. (33) Since technology makes cooking so much faster, people are willing to make several dishes for even a small meal. Parents are more likely to let children be picky, now that they can easily heat them up some prepackaged cakes and cheese on the side. Needless to say, adults living in the same house may have very different eating habits as well. If they don't want to cook a lot of different dishes, it's common now to eat out at restaurants several times a week.
(34) Healthful eating is also easier than ever now. When people cook, they use new fat substitutes and cooking sprays to cut fat and calories. This reduces the risk of heart disease and other diseases. Additionally, we can buy fruits and vegetable fresh, frozen or canned. They are easy to prepare, so many of us eat more of those nutritious items daily. Our lifestyle. is fast, but people still like good food. (35) What new food preparation technology has given us is more choices. Today, we can prepare food that is more convenient, healthier, and of greater variety than ever before in history.
(33)
A．Human lives become worse than ever before.
B．Human lives become better than ever before.
C．Human lives have no change at all.
D．Human lives have changed greatly.

One characteristic common to unsuccessful food innovations has been that, even with extensive government support, they often have not been technologically adapted or culturally acceptable to the people for whom they had been developed. A successful new technology, therefore, must fit the entire sociocultural system in which it is to find a place Security of crop yield, practicality of storage, and costs are much more significant than what had previously been realized by the advocates of new technologies.
The adoption of new food technologies depends on more than these technical and cultural considerations; economic factors and governmental policies also strongly influence the ultimate success of any innovation. Economists in the Anglo-American tradition have taken the lead in investigating the economics of technological innovation. Although they exaggerate in claiming that profitability is the key factor guiding technical change -- they completely disregard the substantial effects of culture—they are correct in stressing the importance of profits. Most technological innovations in agriculture can be fully used only by large landowners and are only adopted if these profit-oriented business people believe that the innovation will increase their incomes, Thus innovations that carry high rewards for big agribusiness groups will be adopted even if they harm segments of the population and reduce the availability of food in a country. Further, should s new technology promise to alter substantially the profits and losses associated with any production system, those with economic power will strive to maintain and improve their own positions. Therefore, although technical advances in food production and processing will perhaps be needed to ensure food availability, meeting food needs will depend much more on equalizing economic power among the various segments of the populations within the developing countries themselves.
The phrase "fall by the wayside" in the second sentence, Paragraph t means"______".
A．decrease
B．fail to continue
C．cancel
D．forget
