The first American public high school, established in Boston in 1821, was only for boys. But as the high-school movement spread, new schools quickly became coed. "Almost right from the beginning, society believed in integration by sex." says David Tyack, an education historian at Stanford University. Now a small group of educators—encouraged by studies that show boys and girls learn differently—are turning to single-sex classrooms as a way to re engage students, especially in low-income communities. One of the first to gain national attention was the Young Women's Leadership School in New York's East Harlem, now considered one of the best public schools in the city. Research on the effect of single-sex schools is mixed, and there are no studies on single-sox classrooms in schools. Experts who study single-sex schools say there's considerable evidence that smaller class sizes would help just as much, especially for middle-class kids. But for boys from poor families, that extra attention and focus can make a difference, says Cornelius Riordan, a sociology professor at Providence College who is directing a study on single-sex schools for the U.S. Department of Education.
Schools all over the country are experimenting with the idea. At Lloyd Memorial High School in Erlanger, Ky., freshmen and sophomores were separated by gender last fall for all classes except one, their elective. At the end of the year, the consensus among teachers and the principal is that single-sex works. Students have mixed views. "You don't have the distraction of boys sitting in your classroom," says Katie Brown, "You can just come to class and you're actually in it to learn, not to impress." But after a joyful all-boys science class (the centerpiece was a generator sending off electric sparks), 14-year-old Zack Craddock thought he would have had just as much fun if there were girls in the class. "I think it's personal," he says. "Some guys would have acted the same and some guys would have acted different. I would have been the same."
Principal John Riehemann originally backed the idea as a way to help boys, who were consistently lagging be hind in reading. One issue: too much of the material was girl-oriented. That led to the even more radical move of separating almost all classes. Riehemann said there were no objections from parents or teachers, and the experiment has worked so well that they're expanding it to juniors in the fall.
According to David Tyack, the popular belief in education is that ______.
A．it is beneficial for girls and boys to study together
B．it is important to give girls equal opportunities to study
C．it is improper to mix boys and girls in classrooms
D．it is more convenient to manage single-sex schools
Communication with Customers Online
Until the late 1940s, when television began finding its way into American homes, companies relied mainly on print and radio to promote their products and services. The advent (出现) of television brought about a revolution in promoting products and services. Between 1949 and 1951 , advertising on television grew 960 percent. Today the Internet is once again transforming promotion. By going online, companies can communicate instantly and directly with prospective customers. Promotion on the World Wide Web includes advertising, sponsorships and sales promotions like contests and coupons. In 1996, world wide web advertising revenues reached $ 300 million.
Effective online marketers do not merely transfer hard-copy ads(平面广告) to cyberspace. Successful sites blend promotional and non-promotional information, indirectly delivering the advertising messages. To encourage visitors to their sites and to create and cultivate customers' loyalty, companies change information frequently and provide many opportunities for interaction.
One of the best online promotion web sites is the Ragu Web site. Here visitors can find thirty six pasta recipes, take Italian lessons, and view an Italian film festival. But they will find no traditional ads. So subtle is the mix of product and promotion that visitors hardly know an advertising message has been delivered. SEGA of America, maker of computer games and hardware, uses its Web site for a variety of different promotions, such as introducing new game characters to the public and supplying Web surfers the opportunity to down load games. Sega' s home page averages 250, 000 visitors a day. To heighten interest in the site, SEGA bought an advertising banner on Netscape, thereby increasing site visits by 15 percent. Online participants in Quaker Oats' Gatorade promotion received a free T-shirt in exchange for answering a few questions. Quaker Oats reports that the online promotion created product loyalty and helped the company know its customers better.
Now, to target specific Internet users, an increasing number of companies are using "push" technology which automatically delivers customized (按客户要求制造的) news and other information to users' computers when they log onto the Internet. Although organizations like Nielsen Media Research are developing technologies to enhance audience measurement and tracking, it remains difficult to assess how many times the same person looks at an ad and who that person is. Although online promotions can be glamorous and sophisticated, they are not perfect. For a well-designed marketing mix, industry experts advise companies to use the Internet as a supplement to other advertising media.
Internet, like television, has brought great changes to the promotion of products and services.
A．Right
B．Wrong
C．Not mentioned

Today, an estimated two-thirds of all products in supermarkets contain genetically-engineered ingredients, including tortilla chips, drink mixes, taco shells, veggie burgers, muffin mix, and baby formulas. However, only one-third of Americans are aware that their food contain genetically-engineered ingredients, despite the findings of surveys that 85 to 90% of consumers want clear labeling of all genetically-engineered foods. Because labeling is not yet required by government regulations, nor practiced by biotech companies, there is no way for consumers to know what it is that they are eating. The public has not been adequately educated of the presence of genetically-modified ingredients in their diets and the possible risks that these foods may entail, and hence, they have been disempowered in their fights to make informed choices.
Furthermore, the inadequate efforts to educate the public on genetic engineering have been sketchy at best, as some genetic scientists have been presenting the complex process of genetic modification to the public as a simple operation. They have been erroneously giving the impression that "... one gene controls one character trait, and transferring the gene results in the transfer of the corresponding trait to the genetically-modified organism, which can then pass it on indefinitely to future generations". However, the process of genetic modification is random and can cause damage in normal genes when imperfections in the genetic code of one organism are unknowingly passed to the receiving organism. Such publications promoting "public understanding" also do not include relevant findings that show that genes function in an "... extremely complex, interconnected network, so that ultimately, the expression of each gene depends on that of every other". The introduced gene may act differently when working within its new environment. For example, there are "position effects", which can lead to unpredictable changes in the pattern of gene expression and genetic function, such as production of potentially toxic products.
The credibility of these geneticists is also questionable because almost all established molecular geneticists have "... some industrial ties, thus limiting what they can research on, particularly with regard to safety". The connections between big business and genetically- modified foods is an issue in and of itself, as it seems that biotech companies have put economic gains before safety concerns. Because the current state of biotechnology is one of misinformation and lack of information, there are moral/ethical questions raised about the responsibility of these companies, as well as the government, to regulate these industries and protect the public.
There is no way of knowing the overall, long-term effects of genetically-engineered foods on human health. This unpredictability appears to be causing the most controversy over genetically-modified foods, as there is insufficient evidence and need for further research. Moreover, the current claims for genetic engineering are misleading, and there appears to be much ignorance and/or corruption at the top with the biotech corporations, as well as the government, which seem to be more interested in short-term economic gains than in properly informing and protecting the people.
Most Americans______.
A．buy genetically-engineered foods
B．know the foods they buy are genetically engineered
C．want genetically-modified foods to be clearly labeled
D．eat genetically-modified foods
