单选题{{B}}Passage Three{{/B}} The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance or the ecological(生态的)balance as it is known. Many of these waste products can be prevented or disposed(处理) of sensibly, but clearly while more and more new goods are produced and made complex, there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people therefore see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing population. However, the land itself is gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers(人造肥料) cannot bring back the balance. Whatever is underlying(潜在的)reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter(杂乱的废物)and waste. Food is wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. Advertising has helped this process by persuading many of us to buy things we don't want to buy. Pollution and waste continue to be a problem everyone can help to solve by cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.

单选题{{B}}Passage Five{{/B}} Nanotechnology, according to its fans, will jump-start a new industrial revolution with molecular-sized structures as complex as the human cell and 100 times stronger than steel. The new technology transforms everyday products and the way they are made by manipulating atoms so that materials can be shrunk, strengthened and lightened all at once. To date only modest nanotech-based products—such as stain-resistant fabrics and fresh food packaging—have entered the market, but some scientists predict nanotechnology will eventually be the only game in town. "It will be a ubiquitous technology," said George Stephanopoulos, professor of chemical engineering at the Massachusetts Institute of Technology. He echoes other nanotech supporters who say industrial countries are already sliding toward its use in every aspect of manufacturing. Aided by recent advances in microscopes, scientists can now place single atoms where they want for the first time. The potential applications are numerous, with microscopic computers, cancer-killing antennae and nonpolluting car engines on the distant horizon. When it's all going to happen, though, is another matter. According to most scientific accounts, the nanotech future may be 10 to 20 years off. Major hurdles need to be jumped. First, there is a lack of economic mass production. Some of the more complicated devices would require exact placement of billions of atoms. "It may take the lifetime of the universe to complete the construction of (such a) device," said George Barbastathis, assistant professor at MIT. Another challenge is bridging the nanoscale and macroscopic, he said. In other words, the smallness of a nano device is useless when it must be attached to large wires. It's unclear how scientists will overcome these problems. And fears derived from science fiction threaten to derail nanotechnology even as it emerges, in much the same way popular anxiety over "super-weeds" and "frankenfoods" have hobbled biotechnology in agriculture and fear of "designer babies" has set back stem-cell research. Lured by a market with billions of dollars in potential profits, giants like GE, Intel, Motorola and IBM are already heavily involved in research. Worldwide, the two industries with the potential to win big with nanotechnology are electronics and biotechnology, according to MIT researchers. On the biotech front, scientists are promoting the notion of nanoparticles made from gold that could be triggered remotely to heat and kill individual cancer cells. Nanotechnology holds equal promise for wealth creation, hut there isn't a consensus among venture capitalists on how to realize it. "Which direction is it going to work out in? That's the question on everyone's mind," Gang Chen, an associate professor at the MIT, told scientists at a Boston nano gathering.

单选题In a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japanese preschools are not the ones Americans expected to find. In most Japanese preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japanese respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents chose this as one of their top three choices. To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japanese children are taught to read at home by their parents. In the recent comparison of Japanese and American preschool education, 91 percent of Japanese respondentschose providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented Americans listed group experience as one of their top three choices. An emphasis on the importance of the group seen in Japanese early childhood education continues into elementary school education. Like in America, there is diversity in Japanese early childhood education. Some Japanese kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and secondary schools. Some Japanese parents believe that if their young children attend a university-based program, it will increase the children"s chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens.

单选题Car makers have long used sex to sell their products. Recently, how. ever, both BMW and Renault have based their latest European marketing campaigns around the icon of modern biology. BMW's campaign, which launches its new 3-series sports saloon in Britain and Ireland, shows the new creation and four of its earlier versions zigzagging around a landscape made up of giant DNA sequences, with a brief explanation that DNA is the molecule responsible for the inheritance of such features as strength, power and intelligence. The Renault offering, which promotes its existing Laguna model, employs evolutionary theory even more explicitly. The company's television commercials intersperse clips of the car with scenes from a lecture by Steve Jones, a professor of genetics at University of London. BMW's campaign is intended to convey the idea of development allied to heritage. The latest product, in other words, should be viewed as the new and improved scion of a long line of good cars. Renault's message is more subtle. It is that evolution works by gradual improvements rather than sudden leaps (in this, Renault is aligning itself with biological orthodoxy). So, although the new car in the advertisement may look like the old one, the external form conceals a number of significant changes to the engine. While these alterations are almost invisible to the average driver, Renault hopes they will improve the car's performance, and ultimately its survival in the marketplace. Whether they actually do so will depend, in part, on whether marketers have .read the public mood correctly. For, even if genetics really does offer a useful metaphor for automobiles, employing it in advertising is not without its dangers. That is because DNA's public image is ambiguous. In one context, people may see it as the cornerstone of modern medical progress. In another, it will bring to mind such controversial issues as abortion, genetically modified foodstuffs, and the sinister subject of eugenics. Car makers are probably standing on safer ground than biologists. But even they can make mistakes. Though it would not be obvious to the casual observer, some of the DNA which features in BMW's ads for its nice, new car once belonged to a woolly mammoth—a beast that has been extinct for 10,000 years. Not, presumably, quite the message that the marketing department was trying to convey.

单选题{{B}}Text 4{{/B}} Erroneous virtues are running out of control in our culture. I don't know how many times my 13-year-old son has told me about classmates who received ＄10 for each "A" grade on their report cards—hinting that I should do the same for him should he ever receive an A. Whenever he approaches me on this subject, I give him the same reply: forget it! This is not to say that I would never praise my son for doing well in school. But my praise is not meant to reward or elicit future achievements, but rather to express my genuine delight in the satisfaction he feels at having done his best. Doling out ＄10 sends out the message that the feeling alone isn't good enough. As a society, we seem to be on the brink of losing our internal control—the ethical boundaries that guide our actions and feelings. Instead, these ethical standards have been eclipsed by external "stuff" as a measure of our worth. We pass this obscene message on to our children. We offer them money for learning how to convert fractions to decimals. Refreshments are given as a reward for reading. In fact, in one national reading program, a party awaits the entire class if each child reads a certain number of books within a four-month period. We call these things incentives, telling ourselves that if we can just reel them in and get them hooked, then the internal rewards will follow. I recently saw a television program where unmarried, teenage mothers were featured as the participants in a program that offers a ＄10 a week "incentive" if these young women don't get pregnant again. Isn't the daily plight of being a single, teenaged mother enough to discourage them from becoming pregnant again? No, it isn't, because we as a society won't allow it to be. Nothing is permitted to succeed or fail on its own merits anymore. A staple diet of candy bars makes an ordinary apple or orange seem sour. Similarly, an endless parade of incentives corrodes our ability to feel a genuine sense of inner peace (or inner conflict). The simple virtues of honesty, kindness and integrity suffer from an image problem and are in desperate need of better publicity. One way to do this is by example. I fear that in our so-called upwardly mobile world we are on a downward spiral towards becoming morally bankrupt. We may soon render ourselves worthless inside, while desperately clinging to a shell of appearances.
