单选题{{B}}Passage Two{{/B}} Hazardous products are being pushed on the Third World in increasing volume. There are many examples of these: pharmaceutical (处方的) drugs, contraceptives (避孕药) and pesticides banned years ago in Europe, America, or Japan but sold by companies of these same countries to the Third World; cigarettes with a far higher tar(焦油) and nicotine contents than in the rich countries. The health effects on Third World peoples are terrible. The hazardous technologies and products imported from the industrialized countries often displace local technologies and products that may be more appropriate to meet the production and consumption needs of the Third World. Labor intensive technologies that provide employment for the community and are in harmony with the environment are replaced with capital intensive modern technologies that in many instances are ecologically destructive. Appropriate products are replaced by modem products that are thrust upon the people through high powered advertising, sales promotions and pricing policy. The modem industrial system has changed the face of Third World agriculture. In many Third World societies, under the new plantation system, much of the lands formerly planted with traditional food crops have been converted into cash-crop production for export. If export prices are high, the incomes obtained could be higher for export-crop farmers; but when prices fall, as they have in recent years, the farmers are not able to buy enough food with their incomes, and also many agricultural workers lose their jobs. The so-called Green Revolution is a package program that makes it possible to grow more than one crop per year through the introduction of high-yielding seed varieties, high doses of chemical fertilizers and pesticides, agricultural machinery and irrigation. In many areas where this "revolution" wa9 implemented, there was an initial rise in production because more than a single crop could be produced in a year. But the corresponding rise in farmer's incomes was soon offset by the increasing costs of imported chemical inputs and machinery as high- input agriculture only favored richer farmers who could afford to pay for the chemicals and drive out poorer farmers who could not. In addition, the high-yielding crop varieties are very susceptible to pest attacks as insects become resistant to the pesticides. Yields in some areas have dropped. Third World farmers and governments win Increasingly be at the mercy of the transnational food companies.

单选题There are few more sobering online activities than entering data into college-tuition calculators and gasping as the Web spits back a six-figure sum. But economists say families about to go into debt to fund four years of partying, as well as studying, can console themselves with the knowledge that college is an investment that, unlike many bank stocks, should yield huge dividends. A 2008 study by two Harvard economists notes that the "labor-market premium to skill"—or the amount college graduates earned that"s greater than what high-school graduate earned—decreased for much of the 20th century, but has come back with a vengeance (报复性地) since the 1980s. In 2005, the typical full-time year-round U.S. worker with a four-year college degree earned $50,900, 62% more than the $31,500 earned by a worker with only a high-school diploma. There"s no question that going to college is a smart economic choice. But a look at the strange variations in tuition reveals that the choice about which college to attend doesn"t come down merely to dollars and cents. Does going to Columbia University (tuition, room and board $49,260 in 2007～08) yield a 40% greater return than attending the University of Colorado at Boulder as an out-of-state student ($35,542)? Probably not. Does being an out-of-state student at the University of Colorado at Boulder yield twice the amount of income as being an in-state student ($17,380) there? Not likely. No, in this consumerist age, most buyers aren"t evaluating college as an investment, but rather as a consumer product—like a car or clothes or a house. And with such purchases, price is only one of many crucial factors to consider. As with automobiles, consumers in today"s college marketplace have vast choices, and people search for the one that gives them the most comfort and satisfaction in line with their budgets. This accounts for the willingness of people to pay more for different types of experiences (such as attending a private liberal-arts college or going to an out-of-state public school that has a great marine-biology program). And just as two auto purchasers might spend an equal amount of money on very different cars, college students (or, more accurately, their parents) often show a willingness to pay essentially the same price for vastly different products. So which is it? Is college an investment product like a stock or a consumer product like a car? In keeping with the automotive world"s hottest consumer trend, maybe it"s best to characterize it as a hybrid (混合动力汽车) :an expensive consumer product that, over time, will pay rich dividends.

单选题It is desirable that students should acquire some knowledge of the writers whose _______ are placed before them for study.

单选题Mrs. P sneezes violently. Mrs. O says "Bless you!" Mrs. P says "Thank you." Again, this hardly seems to be a case of language being used to communicate ideas, but rather to maintain a comfortable relationship between people. Its sole function is to provide a means of avoiding a situation which both parties might otherwise find embarrassing. No factual content is involved. Similarly, the use of such phrases as "Good morning" or "Pleased to meet you", and ritual exchanges about health or the weather, do not communicate ideas in the usual sense. Sentences of this kind are usually automatically produced, and stereotyped (固定不变) in structure. They often state the obvious (e. g. Lovely day!) or have no content at all (e. g. Hello!). They certainly require a special kind of explanation, and this is found in the idea that language is here being used for the purpose of maintaining rapport (融洽) between people. The anthropologist Malinowski coined the phrase "phatic communication" to refer to this social function of language, which arises out of the basic human .need to signal friendship -- or, at least, a lack of hatred. For someone to withhold these sentences when they are expected, by staying silent, is a sure sign of distance, alienation, even danger. These illustrations apply to English and to many other European languages. But cultures vary greatly in the topics which they permit as phatic communication. The weather is not so universal a conversation filler as English might like to think! For example, women in Burundi, central Africa, upon taking leave, are quite often heard to say, routinely and politely, "I must go home now, or my husband Mil beat me." Moreover, phatic communication itself is far from universal: Some cultures say little, and prefer silence, as in the case of the Paliyans of southern India, or the Aritama of Colombia.
