Historians are understandably reluctant about predicting the future because of all the unknown variables involved. For example, a third world war—employing thermonuclear weapons—could conceivably destroy life on this planet.【C1】______.
Faced with these prospects, the US government undertook to persuade the Canadian government to join in a continental program to exploit and market energy and mineral resources, particularly oil and water, of which Canada is one of the world’s major suppliers. For the industrialized countries, a continental strategy of access to energy and fuel resources appeared to be imperative.
We have singled out the North American resource situation because it illustrates a contemporary phenomenon. Peoples everywhere are caught up in the " revolution of rising expectation" so that in underdeveloped countries men look forward to owning at least a few modern western appliances.【C2】______
It is the application of technology to physical resources that sustains human life and ultimately sets the limits on the number of people who can be fed. But technology also provides the tools and techniques for lengthening life spans and reducing death rates. As a result, high birth rates are no longer closely matched by, high death rates as they were until modern times; infectious diseases are much less frequent in most parts of the world, due largely to public health measures; and physical vitality has been increased by improved nutrition.【C3】______.
In 1000 A. D. the estimated population of the world was 275 million, a figure which had approximately doubled by 1650. But whereas it took some years for this increase to occur, the following 300 years brought a six-fold increase to over three billion people in 1962. In those three centuries some 23 billion people had been born, and the factor of acceleration continues.
Asia, Africa and Latin America have been growing more rapidly than Europe, Russia and North America. In other words, the regions possessing the most advanced technology and highest living standards are likely to be a progressively diminishing portion of the global population.【C4】______.
The scope and urgency of the questions raised by the population explosion are unprecedented.【C5】______. It remains to be seen what effective combined efforts can—or will—be made.
[A] These changes have brought about what is today familiarly called the "population explosion"—which, unless checked, could conceivably become the most serious problem of the next century.
[B] Assuming, however, that mankind can avoid this kind of disaster, it is possible, on the basis of variable data, to make meaningful guesses about feasible developments in man’s physical, political and societal environments for the year 2010, and even beyond.
[C] Last but not least, people in the richer countries of the world could also help save the rainforests by using wood-derived products such as paper more carefully and by recycling used paper products to help reduce the demand for newly cut wood.
[D] On the other hand, it is heartening to note that the interaction relationship between population growth, technological change, and the use of resources has at last been recognized as an international challenge by the member states of the United Nations.
[E] Since economic production is growing faster than biological reproduction in the advanced countries of the West while the reverse situation threatens to occur in the rest of the world during the decades ahead, the resulting imbalance between population growth and economic growth is almost certain to generate massive political and social tensions.
[F] But this psychological phenomenon of our times poses the question; Will the earth’s resources last long enough to enable the entire world to approach the living standards in the industrialized countries of today?
【C4】
选项
答案
E
解析
本题依据句子间的逻辑关系来做。这个空前面的句子是说技术越先进,则在全球人口增长中的比例就越小,而下一段开头是说由“人口爆炸”所带来的问题是史无前例的,因此可推断这一段仍是在谈“人口爆炸”问题,只不过是从发达国家在这一问题中所扮演的角色这个角度来谈起的,故选[E]“分析经济增长与人口增长的关系问题”。
