单选题What do consumers really want? That's a question market researchers would love to answer. But since people don't always say what they think, marketers would need direct access to consumers' thoughts to get the truth. Now, in a way, that is possible. At the "Mind of the Market" laboratory at Harvard Business School, researchers are looking inside shoppers' skulls to develop more effective advertisements and marketing pitches. Using imaging techniques that measure blood flow to various parts of the brain, the Harvard team hopes to predict how consumers will react to particular products and to discover the most effective ways to present information. Stephen Kosslyn, a professor of psychology at Harvard, and business school professor Gerald Zaltman, oversee the lab. "The goal is not to manipulate people's preferences," says Kosslyn, "just to speak to their actual desires." The group's findings, though still preliminary, could radically change how firms develop and market new products. The Harvard group use position emission tomography (PET) scans to monitor the brain activity. These PET scans, along with other non-invasive imaging techniques, enable researchers to see which parts of the brain are active during specific tasks (such as remembering a word). Correlations have been found between blood flow to specific areas and future behavior. Because of this, Harvard researchers believe the scans can also predict future purchasing patterns. According to an unpublished paper the group produced, "It is possible to use these techniques to predict not only whether people will remember and have specific emotional reactions to certain materials, but also whether they will be inclined to want those materials months later." The Harvard group is now moving into the next stage of experiments. They will explore how people remember advertisements as part of an effort to predict how they will react to a product after having seen an ad. The researchers believe that once key areas of the brain are identified, scans on about two dozen volunteers will be enough to draw conclusions about the reactions of specific segments of the population. Large corporations including Coca Cola, Eastman Kodak, General Motors, and Hallmark - have already signed up to fund further investigations. For their financial support, these firms gain access to the experiments but cannot control them. If Kosslyn and Zaltman and their team really can read the mind of the market, then consumers may find it even harder to get those advertising jingles-out of their heads.

单选题{{B}}Directions:{{/B}} There are 5 reading passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C, and D. You should decide on the best choice and mark your answer on the ANSWER SHEET by blackening the corresponding letter in the brackets. A man-made chemical that attracts male gypsy moths by duplicating the natural attractant of female gypsy moths has been patented as No. 3,018,219. Dr. Martin Jacobson of Silver Spring, Md., assigned patent rights to the U. S. Government as represented by the Secretary of Agriculture. The chemical can be used to detect gypsy moth infestations, as well as to control the insects. The gypsy moth does serious damage to forest and shade trees in New England and eastern New York State. The caterpillars, or larvae, of gypsy moths eat the leaves of trees, often causing death by a single attack. Losses of hardwood trees have been estimated at tens of millions of dollars from a 20-year study. Gypsy moths were prevented from spreading to other U. S. forest areas by using the natural attractant of the female to detect infestations, then spraying with chemicals such as DDT to kill the insects. Since the lure could previously be obtained only by clipping the last two abdominal segments of the virgin female moth, extracting the segments with benzene and then processing to stabilize the chemical, the procedure was expensive. Another difficulty was that, as the gypsy moth population declined, it became increasingly hard to obtain the females needed for lure production. Dr. Jacobson overcame both these difficulties by discovering a synthetic method for making the female's attractant chemical. The chemical is known as 12-acetoxy-l-hydroxycis-9- octadecene. It is so potent that the fraction of a drop produced by the female is 200,000 times more than the amount needed to catch a mate. The synthetic chemical is also very powerful--it works in amounts about equivalent to one drop in a box car. The flightless female gypsy moth mates only once a year and, as soon as she does, an enzyme switches off production of the sex attractant. The winged male, however, call mate several times and it is because of this that the chemical is being used for pest control. By using a mixture of attractant and DDT in traps lined with a sticky substance, enough males can be caught to reduce the gypsy moth population substantially.
