单选题{{B}}Passage Four{{/B}} Imagine a world in which there was suddenly no emotion--a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive: knowing neither joy nor pleasure, anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotional world would lack rewards and punishments. Society would soon disappear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a World without' friends or enemies, there could be no marriage, affection among companions, or bonds among members of groups. Society's economic underpinnings (支柱) would be destroyed: since earning $10 million would be no more pleasant than earning ＄10, there would be no incentive to work. In fact, there would be no incentives of any kind. For as we will see, incentives imply a capacity to enjoy them. In such a world, the chances that the human species would survive are next to zero, because emotions are the basic instrument of our survival and adaptation. Emotions structure the world for us in implant ( 嵌入, 插入)ways. As individuals, we categorize objects on the basis of our emotions. True, we consider the length, shape, size, or texture, but an object's physical aspects are less important than what it has done or can do to us--hurt us, surprise us, anger us or make us joyful. We also use categorizations colored by emotions in our families, communities, and overall society. Out of our emotional experiences with objects and events comes a social feeling of agreement that certain things and actions are "good" and others are "bad", and we apply these categories to every aspect of our social life--from what foods we eat and what clothes we wear to how we keep promises and which people our group will accept. In fact, society exploits our emotional reactions and attitudes, such as loyalty, morality, pride, shame, guilt, fear and greed, in order to maintain itself. It gives high rewards to individuals who perform important tasks such as surgery, makes heroes out of individuals for unusual or dangerous achievements such as flying fighter planes in a war, and uses the legal and penal (刑法的) system to make people afraid to engage in antisocial acts.

单选题{{B}}Passage Four{{/B}} Without question there are plenty of bargains to be had at sales time—particularly at the top-quality shops whose reputation depends on having only the best and newest goods in stock each season. They tend, for obvious reasons, to be the fashion or seasonal goods which in due course become the biggest bargains. It is true that some goods are specially brought in for the sales but these too can provide exceptional value. A manufacturer may have the end of a range left on his hands and be glad to sell the lot off cheaply to shops; or he may have a surplus of a certain material which he is glad to make up and get rid of cheaply; or he may be prepared to produce a special line at low cost merely to keep his employees busy during a slack period. He is likely to have a good many "seconds" available and if their defects are trifling these may be particularly good bargains. Nevertheless, sales do offer a special opportunity for sharp practices and shoppers need to be extra critical. For example the "second" should be clearly marked as such and not sold as if they were perfect. (The term "substandard", incidentally, usually indicates a more serious defect than "seconds".) More serious is the habit of marking the price down from an alleged previous price which is in fact fictitious. Misdescription of this and all other kinds is much practiced by the men who run one day sales of carpets in church halls and the like. As the sellers leave the district the day after the sale there is little possibility of {{U}}redress{{/U}}. In advertising sales, shops may say "only 100 left" when in fact they have plenty more; conversely they may say "10 000 at half-price" when only a few are available at such a drastic reduction. If ever the warning "let the buyer beware" were necessary it is during sales.

单选题 A recent report on population trend conducted by the think {{U}}(1) {{/U}} of the World watch Institute identifies signs of slowing growth in some countries. It says populations in 32 countries—all in the industrialized world—have stabilized because of declining birthrates. But in a handful of developing countries where population is slowing, the cause isn't something to {{U}}(2) {{/U}}, because more people are dying. This trend is called "population fatigue", and it's beginning in many of the developing countries that have experienced {{U}}(3) {{/U}} birthrates and sharp population growth for several decades. Governments in these countries are now having trouble dealing with feeding, housing and educating an increasing number of children, {{U}}(4) {{/U}} at the same time confronting the falling water {{U}}(5) {{/U}}, deforestation and soil erosion that rapid population growth brings. In these countries any new threat—infectious disease, drought or famine—can become a {{U}}(6) {{/U}} crisis. AIDS is a case {{U}}(7) {{/U}}. WHO estimates calculate that one-quarter of the adult population of Zimbabwe and Botswana are infected with the AIDS virus, {{U}}(8) {{/U}}, these countries stands to lose at least one-quarter of their labor force in the next decade from AIDS alone, a situation {{U}}(9) {{/U}} since the yellow fever swept through Europe in the 14'h century. Social unrest is also increasing in these countries. One example is the {{U}}(10) {{/U}} conflict between the Tutsis and the Hutus in Rwanda, where population pressures reduced cropland {{U}}(11) {{/U}} where it could no longer feed those who lived on it. Demands on the world fisheries and shared water resources are likely to spark similar conflicts. Already the waters of the Nile are so heavily used that little reaches the Mediterranean, so any increase in demand or {{U}}(12) {{/U}} in allocation will also increase tensions. The bottom line is that human population growth is {{U}}(13) {{/U}} to slow one way or the other. Developing societies will either recognize problems {{U}}(14) {{/U}} the horizon and act to encourage smaller families — or unchecked births will have their {{U}}(15) {{/U}} in rising death rates.
