单选题 There are three additional factors that should be cited in order to ensure greater success in the youth market. The first is that the youth group is a perpetually new market. As consumers move into this market, the advertiser needs to attract them, since every brand is a new brand to someone who has never used it before. This stream of young consumers moves along in age and finally drifts into an older pool of householders. Thus, a marketer must not neglect young consumers who come "on stream" if the company's brand is to have continued success in the older-age market. A second point to remember is that companies may be able to utilize youth appeals to a market broader than the traditional age boundary would indicate. Marketers today are defining "youth" more in terms of a state of mind than of a specific age. The result of this is that many companies, ranging from retailers to manufacturers, are broadening their emphasis to include the mature and more affluent customers who "think young". A final point for the market to recognize is the growing and global nature of the market. The youth market will increase worldwide. Moreover, there appears to be a growing homogenization of the teenage market worldwide. Many companies see teen tastes and attitudes as being sufficiently similar to warrant (保证，使有正当理由) a global advertising and marketing strategy. If there is a generic type of teenager emerging globally, this has important implications for marketers. First, sheer market size is staggering (令人惊愕的)—1.37 billion people, or 26 percent of world population, aged 10 to 19 in 1990—and there is a trend of teens in industrialized nations spending a higher percentage of their parents' disposable income. Second, a danger lurks in this market for U.S. marketers. They must recognize that the United States may not remain the cultural nerve center for teens. Constant travel and attention to new ideas generated abroad are necessary, rather than assuming an automatic reliance on the primacy of U.S. cultural exports.

单选题This is ______ the advertising for these products wants to make US think.

单选题Colleges in the US have added a new subject, “great chemistry”, to their curriculum today. “Green chemistry (53) how we can develop products that won’t (54) the environment,” explains Paul Anastas, director of Yale University’s Center for Green Chemistry and Green Engineering, opened at the beginning of this year. The American Chemical Society, (55) approves more than 600 college chemistry programs, only lists about a dozen that teach green chemistry. But that (56) is growing.Cambridge College in Massachusetts is offering “ an introduction to green chemistry” course this gall and is offering the nation’s first bachelor’s and master’s (57) in green chemistry. The program will have classes in environmental science and even environmental (58) and policy. These subjects are not (59) taught to chemistry major.Employers (60) the introduction of green chemistry. Businesses are increasing seeking graduates (61) backgrounds in the subject because it can help them make or save money in he development and manufacturing of products. “We need people who can not only understand their place (62) , but also understand the worldwide perspective,” said Adam Peterson, a chemical division manager at Dow Corning Corp.

单选题Directions: There are 4 passages in this part. Each of the passages is followed by 5 questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D.{{B}}Passage One{{/B}} On cold days in Delhi, the poor light bonfires (篝火) of tyres, trees and rags whose fumes mix with the exhaust from the city's 2 million vehicles to form a thick smog. On most days in Mexico City, a blanket of pollution cuts off views of the surrounding mountains. On one famous occasion it got so bad that birds fell dead out of the sky on to the Zocalo, the city's main square. Throughout the developing world, smogs in many big cities are getting worse as more people use cars and more manufacturing firms are belching out (喷出) pollution. Congestion is on the rise, too: according to one estimate, a car in Bangkok now spends the equivalent of 40 days a year stuck in traffic. The air in Asia's cities, like the water in its rivers, is particularly unhealthy, containing levels of dust and smoke several times higher than in the rich countries' cities. Environmentalists in the developed world also worry about air pollution in poorer countries, not just out of the goodness of their hearts but because they fear it may affect their own backyard. Carbon-dioxide emissions, thought to be the cause of global warming, are growing particularly fast in developing countries. So are emissions of sulphur dioxide, blamed for acid rain, which sometimes falls hundreds of miles from the source of the pollution. But the harm that air pollution causes in the developing countries themselves is much more serious and immediate. The biggest concern are indoor air pollution, lead emissions and small particles. Indoor pollution in poor countries is not much talked about, but it is often as damaging to health as smoking cigarettes. Around a third of all energy consumed in developing countries comes from wood, crop residues and dung, which are often burnt in poorly designed stoves within ill-ventilated (通风很差的) huts. Studies of women in India and Nepal exposed to smoke from such fuels show that their death rates from chronic respiratory disease are similar to those of heavy smokers. Lead has long been known to be dangerous in large doses. But only since the 1970s have scientists been aware that relatively small quantities of lead in the bloodstream can be harmful to humans. In particular, "many studies show a correlation between levels of lead in children's blood and lower IQ scores, hearing loss and hyperactivity (活动过度). But the kind of air pollution thought to cause the most damage to human health in developing countries is that from small particles. Caused by vehicle exhausts, coal-burning smoke from factories and dust stirred up by vehicles, these particles easily find their way into people's lungs. Studies the world over have shown a strong positive correlation between small particles in the air and death rates.

单选题When imaginative men turn their eyes towards space and wonder whether life exists in any part of it, they may cheer themselves by remembering that life need not resemble closely the life that exists on Earth. Mars looks like the only planet where life like ours could exist, and even this is doubtful. But there may be other kinds of life based on other kinds of chemistry, and they may multiply on Venus or Jupiter. At least we cannot prove at present that they do not. Even more interesting is the possibility that life on their planets may be in a more advanced stage of evolution. Present-day man is in a peculiar and probably temporary stage. His individual units retain a strong sense of personality. They are, in fact, still capable under favorable circumstances of leading individual lives. But man s societies are already sufficiently developed to have enormously more power and effectiveness than the individuals have. It is not likely that this transitional situation will continue very long on the evolutionary time scale. Fifty thousand years from now man s societies may have become so close-knit that the individuals retain no sense of separate personality. Then little distinction will remain between the organic parts of the multiple organism and the inorganic parts (machines) that have been constructed by it. A million years further on man and his machines may have merged as closely as the muscles of the human body and the nerve cells that set them in motion. The explorers of space should be prepared for some such situation. If they arrive on a foreign planet that has reached an advanced stage (and this is by no means impossible), they may find it being inhabited by a single large organism composed of many closely cooperating units. The units may be "secondary"—machines created millions of years ago by a previous form of life and given the will and ability to survive and reproduce. They may be built entirely of metals and other durable (耐用的) materials. If this is the case, they may be much more tolerant of their environment, multiplying under conditions that would destroy immediately any organism made of carbon compounds and dependent on the familiar carbon cycle. Such creatures might be relics of a past age, many millions of years ago, when their planet was favorable to the origin of life, or they might be immigrants from a favored planet.
