Putting in water fountains(?????) at schools, and teaching children about the health benefits of water, could reduce their risk of getting extra pounds, reports a new study that is published in the latest issue of the journal pediatrics.
The findings are based on a survey in 32 elementary schools of two German cities, Dortmund and Essen. The researchers, led by Rebecca Muckelbauer, a nutrionist at the Research Institute of Child Nutrition Dortmund, weighed about 3,000 children, and asked them about their beverage(????) consumption.
At the beginning of the school year, the experts had water fountains added to 17 of the schools. The scientists also worked with teachers to carry out educational programs that promote the benefits of drinking water. In contrast to schools in the United States, there are very few schools in Germany that have water fountains.
At the beginning of the study, there were no big differences in the number of overweight children in different groups. But by the end of the school year, children in the schools with water fountains were 31 percent less likely to gain extra pounds, compared to kids who went to other schools, where water drinking was not encouraged.[???:?
Children in the schools with fountains, increased their water consumption from about 3 up to 4 glasses a day, while those in the other schools continued to drink an average of 3 glasses. Over the research, the number of overweight kids upped from 384 to 385 out of 1,641 at the schools with water fountains. In comparison, the number of overweight kids at the other schools increased from 339 to 364 out of 1,309, Dr. Muckelbauer said.
The experts cannot make any final conclusions and explain why the students who were encouraged to drink water were less likely to gain extra weight. Dr. Muckelbauer noted that according to a few other studies, drinking of water increases the rate at which calories are burned, while some other research suggested that water may temporarily decrease appetite.

B
Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world—especially social networking sites such as My Space—and worry their kids will get in trouble with people they meet.
“The parents see the web’s incredible potential(可能性), and they know their kids have to be there.” says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. “It is also what they are scared of most.”
The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That’s because young people who largely have grown up with the Net think of it as a social outlet(出口), say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog.
Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it’s important to know what their kids are doing online.
Findings suggest both parents and teens need more education about using online media, Steyer says.

For the first time in modem history, less than half of the
Reading a book requires a degree of active attention and devotion. Indeed, reading itself is a progressive skill that depends on years of education and practice. On the contrary, most electronic media such as television, recordings, and radio make fewer demands on their audiences, and indeed often require no more than passive participation. While oral culture has a rich reality and electronic media offer the considerable advantages of variety, print culture affords irreplaceable forms of focused attention and thought that make various communications and views possible. The decline in reading, therefore, equals a larger retreat (减少) from participation in public and cultural life.
