单选题 Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes in the automobile to monitor exhaust and send data on pollution to a microprocessor that will then adjust the engine. They speak of what the New York Times calls "metal-hungry microbes that might be used to mine valuable trace metal from ocean water". They have already demanded and won the right to patent new life forms. Nervous critics, including many scientists, worry that there is corporate, national, international, and inter-scientific rivalry in the entire biotechnological field. They create images not of oil spills, but of "microbe spills" that could spread disease and destroy entire populations. The creation and accidental release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and respectable scientists are talking about possibilities that stagger the imagination. Should we breed people with cow-with stomachs so they can digest grass and hay, thereby relieving the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction times or assemblyline workers designed to do our monotonous work for us? Should we attempt to eliminate "inferior" people and breed a "super-race"? (Hitler tried this, but without the genetic weaponry that may soon issue from our laboratories. ) Should we produce soldiers to do our fighting? Should we use genetic forecasting to pre-eliminate "unfit" babies? Should we grow reserve organs for ourselves, each of us having, as it were, a "savings bank" full of spare kidney, livers, or hands? Wild as these notions may sound, every one has its advocates (and opposers) in the scientific community as well as its striking commercial application. As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? , "Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes commercially practical, a new consumer need will be exploited and a market for the new technology will be created. "

单选题Never mind the fight to get people to open their wallets in the recession—some companies are taking a different policy，and trying to get customers to open their purses instead．In America，where female consumers make more than 80％ of discretionary purchases，companies have started tailoring their products and messages to appeal to women，in an effort to boost their sales． Frito-Lay，a snack-food company owned by PepsiCo，has launched a campaign called“Only In A Woman’s World”to convince women that crisps and popcorn are not just for male，beer-guzzling sport fans．OfficeMax，American second-largest office-supplies company，has redesigned its notebooks and file-holders to appeal to women and has run advertisements that encourage women to make their office more colorful．For the first time，MCDonald’s was a sponsor of New York Fashion Week in February，promoting a new line of hot drinks t0 trendsetting women． Eric Almquist，head of global consumer insights for Bain&Company，says he is surprised it has taken a recession to get companies to focus on women．After all，it is hardly news that they control the vast majority of consumer spending．(They buy 90％of food，55％of consumer electronics，and most of the new cars．)But the recession has prompted companies to rethink their approach．She speaks that helps companies including Citibank and Philips reach women consumers，has tripled its number of clients since the recession began．Some women’s magazines，too，are benefiting as companies that had never before expressed interest in advertising with them are now doing so． Aside from their greater purchasing power，women are valuable customers for three reasons．First，they are loyal，says Marti Barletta，author of Marketing to Women，and more likely to continue to buy a brand if they like it．Second，women are more likely than men to spread information about products they like through word of mouth and social-networking sites．Third，most of the lay-offs so far in America have been in male dominated fields，like manufacturing and construction．This means women may bring home a greater share of household income in the months ahead and have even more buying power． But marketing to women may not work for every company．In particular，for firms(such as some carmakers)with brands that are regarded as strongly male，“gender bending”．or trying to attract the opposite sex，could enhance short-term sales but cause a longer-term decline．Jill Avery of the Simmons School of Management in Boston researched this trend with cars．When Porsche released a sport-utility vehicle designed for women，sales temporarily increased，but men started to move away from the brand，on the basis that it had compromised its masculine image．But in this recession，having a tarnished brand is better than having no brand at all．

单选题Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: Whether language, complete with grammar, is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D.C., the world's only liberal arts university for deaf people. When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd: Among themselves, students signed differently from his classroom teacher. Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language(ASL)was thought to be no more than a form of pidgin English(混杂英语). But Stokoe believed the "hand talk" his students used looked richer. He wondered: Might deaf people actually have a genuine language? And could that language be unlike any other on Earth? It was 1955, when even deaf people dismissed their signing as "substandard". Stokoe's idea was academic heresy(异端邪说). It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation(调节)of sound. But sign language is based on the movement of hands, the modulation of space. "What I said," Stokoe explains, "is that language is not mouth stuff—it's brain stuff."

单选题From: Paul Rooney ＜rooneyhoy@speedmail.com＞ To: Green Mountain Stationery, Inc ＜pgmountain@qmail.com＞ I have been purchasing various products through your catalog for many years. For the most part, I've been quite satisfied. However, I recently ordered a case of 1,000 envelopes for my business and am extremely disappointed. First of all, the envelopes I received differ from the description in your catalog. They are supposed to be nine inches long, but the envelopes I received are six inches long. Second, the adhesive on the envelops is defective. I attempted to use a dozen of them. and none of them remained properly sealed. At the very least, I would like a refund for the full cost of these envelopes, along with the shipping charge. The total amount I paid was $34.68. Furthermore, the inspection sticker on the carton states that the product was inspected at your Burlington warehouse. I would like to know how this mistake occurred and request your assurance that this sort of thing will not happen again in the future. Otherwise, I am afraid that I will have to take my business elsewhere. From: Sharon Park ＜pgreeenmountain@qmail.com＞ To: Paul Rooney＜rooneyhoy@speedmail.com＞ Dear Mr.Rooney, My name is Sharon Park, and I am the director of quality control at Green Mountain Stationery. Inc. I was recently made aware of your complaint by one of our customer service representatives. I would like to start by apologizing for any inconvenience you may have experience. Our accounting department will issue you a full refund of $34.68 for the defective envelopes. We would also like to offer you a $50 gift certificate that can be used with the purchase of any product in our catalog. I must acknowledge that there have been some problems with inspections in our Burlington warehouse. To deal with this issue, the company has decided that the entire inspecting staff will take part in an intensive re-training program. We will review our procedures to identify anything that needs to be improved. I have forwarded your message to our entire management team, to ensure that this issue will not be overlooked. I am sorry that we have disappointed you, and I sincerely hope you continue to purchase our products. I'm sure this was a one-time incident that will not happen again. Please don't hesitate to contact me directly in the future if you have any questions or concerns. Sincerely, Sharon Park
