第一篇 Volunteers are being recruited(征募) to eat raw potatoes in the first human trials of a vaccine grown in genetically engineered vegetables. Researchers in Texas hope that people who eat the potatoes will be protected against common gut(肠，肠子) infections. They believe this technique could prove to be a cost-effective way of growing vaccines in developing countries where such diseases are still killers. Other researchers previously succeeded in using similar techniques to produce potential vaccines Now Hugh Mason and his colleagues at Texas A & M University(得克萨斯农业及机械大学) their plant vaccines on mice and plan to recruit 15 volunteers for a human trial. The team first tested the technique in tobacco plants. They took a strain of Escherichia coli(大肠杆菌) bacteria that causes food poisoning, and identified the part of the poison which binds to its victims gut cells. They then used a modified plant bacterium called Agrobacterium tumefasciens to transfer the segment of DNA which manufactures the binding protein into the tobacco plant. Under normal circumstances, these bacteria transfer packets of DNA into plant cells to force the plant to manufacture the nutrients they need. But in the modified bacteria, the DNA package includes the gene to pro- duce the binding protein. Once the foreign DNA segment was incorporated(结合，合并) into the tobacco's own DNA, the bacteria were killed off with antibiotics. Mason's team then grew these modified tobacco plants and found that they produced the E. coli binding protein. Proof of success came when the tobacco leaves were mashed up(捣碎) and squirted into the stomachs of mice. Mason says that within days the mice started producing specific antibodies to the E. coli poison, but suffered no ill effects from digesting the binding protein. Mason then produced genetically engineered potatoes and fed these to mice, with similar results. Mason's team have used plants to produce vaccines against a number of other infectious agents. For example, they have made a vaccine using a protein from the shell of the Norwalk virus, which causes diarrhoea(腹泻) in children. A third vaccine has also been produced in tobacco using a surface protein from the hepatitis B virus. But Mason says that so far they have only been able to produce small amounts of it in potatoes. Although a vaccine already exists against hepatitis B, a cheaper plant version could make mass immunisation(群众性免疫) possible. One problem with growing potatoes to produce vaccines is that cooking tends to destroy the protein component of the vaccine, so they must be eaten raw. Mason thinks that bananas may be a better option. "One banana could potentially produce a whole host of different vaccines," says Mason. The purpose of this text is______。 A. to prove that doctors don't like vegetables B. to amuse the reader by telling some funny things C. to describe how vegetables can grow vaccines for their own use D. to tell the reader about a cheaper way of growing vaccines

阅读下面的资料,请回答:（）参考下面的资料,如何进行市场细分 营销人员的目标是将一个市场的成员按照某种共同的特性划分成不同的群体。市场细分的方法经历过几个阶段。最初,因为数据是现成的,调研人员采用了基于人口统计学信息的市场细分方法。他们认为不同的人员,由于其年龄、职位、收入和教育的不同,消费模式也会有所不同。后来,调研人员增加了消费者的居住地、房屋拥有类型和家庭人口数等因素,形成了基于地理人口统计学信息的市场细分方法。后来,人们又发现基于人口统计学的方法做出的同一个市场细分下,还是存在着不同的消费模式。于是调研人员根据消费者的购买意愿、动机和态度,采用了基于行为科学的方法来进行分类。另一种形式是基于心理描述图的市场细分方法,划分依据是消费者生活方式的特征。总之,市场细分分析是一种对消费者思维的研究。对于营销人员来说,谁能够首先发现新的划分客户的依据,谁就能获得丰厚的回报。营销人员需要研究市场上不同消费者对于产品属性、价格、渠道、送货时间等方面的各种要求。由此,购买者将被分成不同的群体,每一个群体会对某一方面的产品、服务有特定要求,每一个群体都可以成为一个细分市场,企业可以根据其特殊性提供服务
