单选题From the perspective of the poor, it seems obvious that the benefits would outweigh the costs. The benefits to poor people of no longer being poor would be enormous. Their intake of protein and other nutrition would increase their choice of housing and the quality of the housing they select would improve. Crimes related to poverty(that the poor generally commit against each other)— murder, rape, robbery, burglary, child abuse, spouse abuse, and drug related crimes—would probably decrease. Apart from these specific improvements, the poor would benefit by an increase in the control over their own lives. Increased purchasing power represents a part of this. More money to spend not only permits the purchase of additional goods and services but greatly widens the choice of goods and services that potentially could be purchased. The poor, if no longer poor, would also gain greater control of various non-fiscal aspects of their lives. As their economic stake in society increases, their political stake is likely to increase as well. They will note more, and thus exercise a greater influence in municipal, local, state, and federal elections. As a result, elected officials will respond to them more effectively. Agencies of government—police, fire, sanitation, streets, parks, and so forth—will also respond more promptly and effectively. Public school systems in particular will be more responsive. The former poor who dislike the education their children are getting in public schools will have an increased ability to " vote with the dollars " by enrolling their children in previously unaffordable private schools or moving to living quarters in previously unaffordable communities. Responding to the former poor will become a matter of survival for the teachers and administrators who depend for their livelihood on the public schools. While the benefits to the poor of enjoying a right not to be poor may for the most part be obvious, some potential disadvantages—to them — should also be considered. First, will not the creation of a right not to be poor reduce the motivation of the poor to exert themselves to get out of poverty? It is arguable that to the extent that self-help is rendered unnecessary to achieve a minimum living standard, many of the poor will refrain from enrolling in the schools, undertaking the enterprises, and in general taking the risks that today elevate many of them not only above the poverty line but into the middle class and beyond. The establishment of a right not to be poor could result, arguably, in the poor as a whole—or at least a substantial percentage of them—ending up economically worse off in the long run. Second, to the extent that a guarantee of non-poverty reduces the poor's incentive to exert themselves, will there not be a parallel reduction in their innovative contributions to the economic well-being of our entire society—including the well-being of the former poor along with the well-being of the rest of us? In other words, a guarantee of non-poverty may arguably induce the poor child — whose deprivation would otherwise have spurred the child to graduate from high school, finish college, get a Ph.D. in physics, and win the Nobel Prize for devising a way to produce cheaper energy — to refrain, because of the security offered by the guarantee, from embarking on a course that would greatly benefit all former poor people as well as society as a whole.

单选题The idea of public works projects as a device to prevent or control depression was designed as a means of creating job opportunities for unemployed workers and as a "pump-priming" device to aid business to revive. It was conceived during the early years of the New Deal Era (1933--1937). By 1933, the number of unemployed workers had reached about 13 million. This meant that about 50 million people--about one-third of the nation--were without means of support. At first, direct relief in the form of cash or food was provided these people. This made them recipients of government charity. In order to remove this stigma and restore to the unemployed some measure of respectability and human dignity, a plan was devised to create governmentally sponsored work projects that private industry would not or could not provide. This would also stimulate production and revive business activity. The best way to explain how this procedure is expected to work is to explain how it actually worked when it was first tried. The first experiment with it was the creation of the Works Project Administration (WPA). This agency set up work projects in various fields in which there were many unemployed. For example, unemployed actors were organized into theater projects, orchestras were organized for unemployed musicians, teaching projects for unemployed teachers, and even writers' projects for unemployed writers. Unemployed laborers were put to work building or maintaining roads, parks, playgrounds, or public buildings. These were all temporary "work relief" projects rather than permanent work opportunities. More substantial work projects of a permanent nature were organized by another agency, the Public Works Administration (PWA). This agency undertook the planning of construction of schools, houses, post offices, dams, and other public structures. It entered into contracts with private construction firms to erect them, or it loaned money to local or state governments which undertook their construction. This created many jobs in the factories producing the material as well as in the projects themselves, and greatly reduced the number of unemployed. Still another agency which provided work projects for the unemployed was the Civilian Conservation Corps (CCC). This agency provided job opportunities for youths aged 16 to 20 to work in national parks or forests clearing land, guarding against fires, building roads, or doing other conservation work. In the event of a future depression, the federal government might revive any or all of the above methods to relieve unemployment and stimulate business.

单选题On your answer sheet, circle and black out the letter that best answers the questions below.{{B}}Passage One{{/B}} Obviously, the per capita income of a country depends on many things, and any statistical test that does not take account of all important determinants is misspecified, and thus must be used only for descriptive and heuristic purposes. It is nonetheless interesting--and for many people surprising--to find that there is a positive and even a statistically significant relationship between these two variables: the greater the number of people per square kilometer the higher the per capita income. The law of diminishing returns is not invariably true. It would be absurd to suppose that a larger endowment of land ipso facto makes a country poorer. This consideration by itself would, of course, call for a negative sign on population density. Thus, it is interesting to ask what might account for the "wrong" sign and think of what statistical tests should ultimately be done. Clearly there is a simultaneous two-way relationship between population density and per capita income; the level of per capita income affects population growth just as population, by increasing the labor force, affects per capita income. The argument offered here suggests that perhaps countries with better economic policies and institutions come to have higher per capita incomes than countries with inferior policies and institutions, and that these higher incomes bring about a higher population growth through more immigration and lower death raters. In this way, the effects of better institutions and policies in raising per capita income swamps the tendency of diminishing returns to labor to reduce it. This hypothesis may also explain why many empirical studies have not been able to show a negative association between the rate of population growth and increases in per capita income. One reason why the ratio of natural resources to population does not account for variations in per capita income is that most economic activity can now readily be separated from deposits of raw material and arable land. Over time, transportation technologies have certainly improved, and products that have a high value in relation to their weight, such as most services and manufactured goods like computers and airplanes, may have become more important. The Silicon Valley is not important for the manufacturing of computers because of the deposits of silicon, and London and Zurich are not great banking centers because of fertile land. Even casual observation suggests that most modem manufacturing and service exports are not closely related to natural resources. Western Europe does not now have a high ratio of natural resources to population, but it is very important in the export of manufactures and services. In a parallel way, the striking success of Japan, Hong Kong, and Singapore, with relatively few natural resources per capita, cannot be explained by reliance thereon.

单选题The one accident situation where immediate action must be taken is when a person stops breathing. This might be the result of drowning, electrocution, suffocation, head injury caused by a fall, poisoning or a variety of other accidents. If someone has stopped breathing, however, there may be a simpler cause—the breathing passages may be blocked by food, vomit, saliva or even the tongue... Whatever the cause, it is imperative that breathing is restarted quickly, as otherwise brain damage may result. Act quickly: lay the casualty flat on his back, and pull back the head while holding the jaws clenched. This prevents the tongue from falling back into the throat and blocking the air passages. If any foreign matter like sand or vomit can be seen in the victim's mouth or throat, scoop it out with the fingers. False teeth are a particular hazard and often fall back into the throat of an unconscious person. If breathing does not start immediately, you must begin artificial respiration right away, by breathing directly into the casualty's lungs through the mouth or nose... As you exhale deeply through the casualty's nose, it is necessary to hold their mouth firmly closed. If you are breathing into the mouth, however, pinch the nostrils to stop the escape of air. If the airways are not obstructed you will see the chest of the casualty's lungs. Each time you blow, turn your head to check that there is regular rise and fall of the chest. This must be continued until breathing starts spontaneously, or in any event for at least an hour. As soon as the casualty starts to respond you should see an improvement in his colour, usually after the first dozen or so inflations. When breathing starts, it will be weak and shallow, and will still need assisting. Time your breaths to coincide with those of the casualty, as his breathing gradually strengthens. When breathing has restarted and can continue without help, the casualty will still be unconscious. He should be turned into the "unconscious'' position, preferably with the body slightly higher than the head, and watched carefully to make sure that breathing continues. Don't rush to get him to hospital. It is more important to make sure that breathing is strong and will continue while the casualty is being moved.
