单选题Excerpt 1 From 2003 to 2050, the world"s population is projected to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO 2 ) will be 42% higher in 2050. But that"s too low, because societies that grow richer use more energy. We need economic growth unless we condemn the world"s poor to their present poverty and freeze everyone else"s living standards. With modest growth, energy use and greenhouse emissions more than double by 2050. Excerpt 2 Although the threat of global warming has been known to the world for decades and all countries and leaders agree that we need to deal with the problem, we also know that the effects of measures, especially harsh measures taken in some countries, would be nullified (抵消) if other countries do not control their emissions. Whereas the UN team on climate change has found that the emissions of carbon dioxide would have to be cut globally by 60% to stabilize the content of CO 2 in the atmosphere, this path is not feasible for several reasons. Such deep cuts would cause a breakdown of the world economy. Excerpt 3 Climate change is one of the most important environmental issues facing humankind. Climate change may affect natural ecosystems in a variety of ways. In the short term, climate change can alter the mix of plant species in land ecosystems such as grasslands. In the long term, climate change has the potential to dramatically alter the geographic distribution of major vegetation types—savannas, forests, and tundra. Climate change can also potentially alter global ecosystem processes, including the cycling of carbon, nitrogen, phosphorus, and sulfur. Moreover, changes in these ecosystem processes can affect and be affected by changes in the plant species of the ecosystem and vegetation type. All of the climate change-induced alterations of natural ecosystems affect the services that these ecosystems provide to humans. Excerpt 4 Plants and animals adapt to climate change over centuries. At the current estimate of half a degree centigrade of warming per decade, vegetation may not keep up. Climatologist James Hansen predicts climate zones will shift toward the poles by 50 to 75 kilometers a year—faster than trees can naturally migrate. Species that find themselves in an unfamiliar environment will die. Excerpt 5 Scientists have long warned that some level of global warming is a done deal—due in large part to heat-trapping greenhouse gases humans already have pumped skyward. Now, however, researchers are fleshing out how much future warming and sea-level rise the world has triggered. Excerpt 6 The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil fuels or dealing with it.

单选题If income is transferred from rich persons to poor persons, the proportion in which different sorts of goods and services are provided will be changed. Expensive luxuries will give place to more necessary articles, rare wines to meat and bread, new machines and factories to clothes and improved small dwellings; and there will be other changes of a like sort. In view of this fact, it is inexact to speak of a change in the distribution of the dividend in favor of, or adverse to, the poor. There is not a single definitely constituted heap of things coming into being each year and distributed now in one way, now in another. In fact, there is no such thing as the dividend from the point of view of both of two years, and therefore, there can be no such thing as a change in its distribution. This, however, is a point of words rather than of substance. What I mean when I say that the distribution of the dividend has changed in favor of the poor is that, the general productive power of the community being given, poor people are getting more of the things they want at the expense of rich people getting less of the things they want. It might be thought at first sight that the only way in which this could happen would be through a transference of purchasing power from the rich to the poor. That, however, is not so. It is possible for the poor to be advantaged and the rich damaged, even though the quantity of purchasing power, i. e. of command over productive resources, held by both groups remains unaltered. This might happen if the technical methods of producing something predominatingly consumed by the poor were improved and at the same time those of producing something predominatingly consumed by the rich were worsened, and if the net result was to leave the size of the national dividend as defined in Chapter V. unchanged. It might also happen if, by a system of rationing or some other device, the rich were forced to transfer their demand away from things which are important to the poor and which are produced under such conditions that diminished demand leads to lowered prices. Per contra—and this point will be seen in Part Ⅳ. To be very important practically—the share, both proportionate and absolute of command over the country"s productive resources held by the poor may be increased, and yet, if the process by which they acquire this greater share involves an increase in the cost of things that play a large part in their own consumption, they may not really gain. Thus a change in distribution favorable to the poor may be brought about otherwise than by a transference of purchasing power, or command over productive resources, to them, and it does not mean a transference of these things to them. None the less, this sort of transference is the most important, and may be regarded as the typical, means by which changes in distribution favorable to the poor come about.

单选题In general, our society is becoming one of giant enterprises directed by a bureaucratic (官僚主义的) management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, well-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he does not wholeheartedly participate in his work and that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management. The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction or interest in life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings. Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the tight mixture of submissiveness and independence. From that moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one"s fellow competitor creates constant anxiety and stress, the very causes of unhappiness and illness. Am I suggesting that we should return to the pre-industrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities—those of love and of reason—are the aims of all social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.
