They do it late at night when their parents are asleep. They do it in restaurants and while crossing busy streets. They do it in the classroom with their hands behind their back. They do it so much that their thumbs hurt.

  Spurred(刺激) by the unlimited texting plans offered by carriers like AT&T Mobility and Verizon Wireless, American teenagers sent and received an average of 2,272 text messages per month, according to the Nielsen Company一almost 80 messages a day.

  The phenomenon is beginning to worry physicians and psychologists. Dr. Martin Joffe, a pediatrician in Greenbrae,Calif.,recently surveyed students at two local high schools and said he found that many were routinely sending hundreds of texts every day.

  The rise in texting is too recent to have produced any conclusive data on health effects. But Sherry Turkle, a psychologist who has studied texting among teenagers in the Boston area for three years,said it might be causing a shift in the way adolescents develop.

  "Among the jobs of adolescence are to separate from your parents,and to find the peace and quiet to become the person you decide you want to be," she said. "Texting hits directly at both those jobs.”

  Psychologists expect to see teenagers break free from their parents as they grow into autono- mous adults,Professor Turkle went on, " but if technology makes something like staying in touch very,very easy, that's harder to do;now you have adolescents who are texting their mothers 15 times a day,asking things like, * Should I get the red shoes or the blue shoes?'"

  The principal of New Milford High School has nearly 12,300 Twitter followers. He and his teachers use Facebook to communicate with students and parents,and students use it to plan e-vents. In class, teachers routinely ask kids to power up their cellphones to respond to classroom quizzes. Rather than ban cellphones, Sheninger calls them "mobile learning devices".

  "The Internet as we know it is the 21st century," he says. "It is what these students have known their whole lives. They're connected, they're creating, they're discussing."

He and others say working online also pushes education beyond the limits of school, allowing kids to broaden discussion of their work. And it forces them to do "authentic" work that gets tested out in the real world, as outside viewers see it and respond to it.

  "Being literate in 2011 means being digitally literate. " says Chris Lehmann. "It is naive (天真的) to think that kids raised online will respond to school the same way as previous genera?tions. Kids are coming to us bored, disconnected, and it's a challenge for us to figure out how to use the tools inherent in the real-time Web.”

  Perhaps the biggest objection to widespread use of social sites is the likelihood that kids will meet irrelevant or even offensive material―a fear that many teachers say is overblown.

  "We as educators need to do a better job of advertising and sharing the meaningful work done with social media," says Matt Levinson. "If you keep it out,kids are creating their own cultures in this space with no guidance from adults―and that's not responsible.”

  "The other big misconception is that schools with open Web access are simply letting kids play freely as if there's no structure," says Lisa Highfill, a longtime devotee of YouTuhe. She used it recently to show her students videos of tornadoes. Highfill says she chooses videos in ad?vance.

  "I don't just search in front of the kids," says Highfill. She admits that even with careful planning,learning online carries risks. But the risks shouldn't be overstated. " When we go on a field trip,when we go anywhere," she says, "we warn students of the dangers of where we're going.”

(   ) 5. In the opinion of Sheninger, social networking        .

   A.is almost the whole life of many kids

   B.gets kids to learn something schools forbid

   C.allows kids to complain about their learning

   D.has kids get feedback on their online work

(   ) 6. According to Chris,teachers are challenged to know        .

   A.how to make full use of social sites in class

   B.how to avoid looking foolish in using social sites

   C.how to connect kids with social media effectively

   D.how to deal with a digital generation in class

   A.online learning is full of unexpected things

   B.it is a risk to open the Web to students at school

   C.teachers provide guidance on the Web access

    D.kids play freely if having access to the Web

 When I was 23 years old I was in a dangerous relationship with my fiance (未婚夫) at the time. I was being physically and verbally abused(辱骂) on a daily basis. I was financially tied to him after he spent all my savings to pay his debts but I wanted to be free!

  For the longest time I was too embarrassed to tell my mother about the situation. She had warned me about him. But,eventually, I worked up the courage to tell her and she sent me the money I needed to leave.

  Before the money arrived he found out what I planned to do. I was so scared of what he might do,so I decided to leave all my things and just get out of there.

  Then,on my way to the safety, my car died!I had automobile insurance so I called the AAA and had them pull the car to a garage. It turned out that the repair was going to cost $80. 00 and the money my mom sent hadn't arrived by that time.

  The owner of the garage must have known something was up because he asked what was wrong. I told him a brief description of my story and told him I could pay him in two days.

  He never told me his name but I will never forget him or what he did for me that day!He fixed the car immediately and told me he would not accept any payment―ever!He said he had a daughter almost my age and would like to think that if she ever needed help in the future then some stranger might do the same for her.

  Since then I have tried to help people in my own way. Now I have a beautiful twelve-year-old daughter and I hope throughout her life she can help others and be helped when she needs it, like I was!
