Recent research from the Pew Internet Project suggests that 90% of Americans aged from 12 to 17 use the Internet, and 51% of those teens use social networks. However, there are many possible problems with social networking sites and the teenagers who use them.
Apart from the social advantages, social networking sites can be used to record school research, develop artistic talents and experiment with other forms of subject creation. They provide a way to communicate with others who share the same interests and to get helpful advice on ongoing projects.
Along with these advantages come some dangers. For example, most social networking sites are open to all, especially MySpace, which is the most popular social network among teens in America. It means that they could be put in unpleasant and frightening situations.
A greater danger is that teens may become objects of the people with secret purposes. The secrecy of some social networking sites makes it easy for dangerous people to find young teens and invite them into dangerous conversations. It’s easy for them to pretend as teens and draw children into dangerous real-world communication as well. Then further hurt might be on its way.
Another danger is identity stealing, which can happen when teens share too much information about their names, dates of birth and locations.
Therefore, it’s very important to make sure teens are safe when they use social networks.
Many of the same rules that work for online chat work for these sites:
※ Don’t use your real name.
※ Don’t give out personal information to people you don’t know. A last name and a town
are enough for a bad guy to find where you are.
※ Don’t believe that people are who they say to be.
※ Immediately end any communication that makes you uncomfortable and report it to a
parent.
Only if you are sure of your safety, can you enjoy the fun brought by social networking. Besides, trying to deal with all problems on your own can lead to terrible results. Remember, asking your parents or school officials for help doesn’t mean you are unable to do anything but wiser than many others.

A recent research shows that physical activity may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P.E. class.
Researchers go over the results of fourteen studies. Twelve were from the United States, one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen.
Thomas Singh, one of the researchers, says the studies showed a relationship between physical activity and scores on subjects such as Math, English and reading. Ms. Singh offers some possible explanations:
“There are, first, physiological (生理的) explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones (荷尔蒙) produced like endorphins (脑内啡). And endorphins make your stress level lower and your mood improved, which means you will perform better in class. Also, students who take part in organized sports, learn rules and how to follow them. This could improve their classroom behavior and help them know what they should do.
All in all, the finding tells us that physically active kids are more likely to do better in school. Ms. Singh says schools should consider the finding before they cut physical education programs.

Snack time is a part of the day for children of all ages. But new research suggests that kids snacking in big groups could be at risk for obesity.
Scientists from American University looked at the eating behavior of 54 kids between the ages of 2 and 6. At snack time, the scientist watched the amount of food each child ate while they were in groups of either three or nine. According to the study, the more children there are in a group, the more likely they are to eat more. Those in the larger group ate nearly 30 percent more than those in the smaller group, and they actually ate faster.
Since this is the first such study in children, scientists are quick to point out the importance of encouraging healthy habits in kids as early as possible.
“If you know kids eat more in large groups, it seems perfect to use this information to keep snack groups small or use small tables,” says Dr. Jana Klauer, an expert in New York.
Smaller groups would allow for a quiet and more relaxing environment-a perfect chance to teach children about food, manners and how to know when they feel full. “This would have an effect on kids' eating,” adds Klauer. “They would slow down and eat less.”

4.The best title of the passage is “ ”
A.Snack Time | B.Different Groups |
C.Eating More | D.Food for Kids |

Researchers have developed paper that can be printed with UV light (紫外线), free from the need for ink (油墨). People can clear the information away on the light-printable paper by heating it to 120°C and it can be reused more than 80 times.
The research was carried out in order to reduce the effects of paper production on deforestation (滥砍滥伐). The researchers, from Shandong University in China and the University of California, Riverside, said that the secret behind the technology is a color-changing chemical. A thin coating of the chemical can be used on usual paper and turn it into a reusable, light-printable one. Heating the paper for 10 minutes can help clear the information away more quickly.
Professor Yadong Yin, a chemistry professor at the University of California and a co-author of the study, said, “The greatest importance of our work is the development of a new technology to produce an ink-free rewritable paper that has the same feel and appearance as usual paper. Our work is believed to have great economic and environmental influences on the modem society.” Paper production has a bad influence on the environment. It’s the main cause of industrial pollution and paper thrown away by people makes up about 40% of landfills where waste is buried under the ground.
It is predicted that light-printable paper will be inexpensive in the future. The printing process is also more cost-effective than the usual one as no ink is needed. Most importantly, it can be reused many times, which greatly reduces the cost.
1.Why did researchers do the research?
A. To make more money by selling the paper. B. To save more ink and more money.
C. To make people interested in writing on the paper. D. To stop people from cutting down more trees.
2.What does the underlined word “it” refer to?
A. Usual paper. B. The chemical. C. The technology. D. Ink.
3.What can’t we know from Paragraph 3?
A. The rewritable paper looks the same as the usual paper. B. Wasted papa: is the most serious pollution.
C. The research will make a difference to our economic development. D. Our environment will be influenced by the rewritable paper.
4.What are the advantages of the rewritable paper?
a. It can be recycled many times.
b. It can help save money.
c. It is environmentally-friendly.
d. It will help save time.
