A few months ago, it wasn't unusual for 47-year-old Carla Toebe to spend 15 hours per day online. She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs – leaving her bed for only brief breaks. Her household bills piled up, along with the dishes and dirty laundry, but it took constant complaints from her four daughters before she realized she had a problem.
　　"I was starting to feel like my whole world was falling apart – kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching (使脱离) herself further from the outside world.
　　Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone.
　　Concern about excessive Internet use isn't new. As far back as 1995, articles in medical journals and the establishment of a Pennsylvania treatment center for overusers aroused interest in the subject. But as reliance on the Web grows, there are signs that the question is getting more serious attention: Last month, a study published in CNS Spectrums claimed to be the first large-scale look at Internet overuse. The American Psychiatric Association may also consider listing Internet addiction in the next edition. And scores of online discussion boards have popped up, on which people discuss negative experiences tied to too much time on the Web.
The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the latest survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling " still occupied by the Internet when offline."
　　"The Internet problem is still in its early stage," said Maressa Orzack, a Harvard University professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. The problem is not limited to porn (色情) or gambling websites.”
　　“Excessive Internet use should be defined not by the number of hours spent online but in terms of losses.”said Maressa Orzack. "If it's a loss where you're not getting to work, and family relationships are breaking down as a result, then it's too much."
　　Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.
　　The website for Orzack's center lists the following among the psychological symptoms of computer addiction:
　　● Having a sense of happiness or excitement while at the computer.
　　● Longing for more and more time at the computer.
　　● Neglect of family and friends.
　　● Feeling empty, depremssed or irritable when not at the computer.
　　● Lying to employers and family about activities.
　　● Inability to stop the activity.
　　● Problems with school or job.
　　Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.
　　“People who struggle with Internet overuse maybe depressed or have other mood disorders.” Orzack said. When she discusses Internet habits with her patients, they often report that being online offers a "sense of belonging, and escape, excitement and fun," she said. “Some people say relief…because they find themselves so relaxed.”
　　Some parts of the Internet seem to draw people in more than others. Internet gamers spend countless hours competing in games against people from all over the world. One such game, called World of Warcraft, is cited on many sites by posters complaining of a "gaming addiction."
　　Andrew Heidrich, an education network administrator from Sacramento, plays World of Warcraft for about two to four hours every other night, but that's nothing compared with the 40 to 60 hours a week he spent playing online games when he was in college. He cut back only after a full-scale family intervention (干预), in which relatives told him he'd gained weight.
　　“There's this whole culture of competition that sucks people in with online gaming, ”said Heidrich, now a father of two. People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly “to remind myself to keep my love for online games in check”.
　　Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line:“I have an Internet Addiction.”
　　“I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work, to take care of my home, to give attention to my children,”she wrote in a message sent to the group. “I have no money or insurance to get professional help; I can't even pay my loan and face losing everything.”
　　Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."
【小题1】 What eventually made Carla Toebe realize she was spending too much time on the Internet?

You maybe surprised to learn that one of the best steps you can take to protect your health is to step outside and spend some time in the grass, dirt and water．

Our ancestors enjoyed the healing power of nature，and now scientists are starting to catch up．According to research in recent years，just having a view of nature has been shown to improve hospital patients' recovery and reduce illness rates among office workers．Also，exposure(曝露) to wildlife，horseback riding，hiking，camping and farms can be helpful for a variety of health conditions in adults and children．

Much of this type of research is focusing on children，and in fact an entire movement has quickly developed to connect kids with the healing power of nature．

Obesity（肥胖）．Rates of childhood obesity have grown sharply in recent years，and this is partly because of reduced outdoor activity time．Increasing the time students spend learning about nature，both in and outside the classroom，would help solve this problem．Such lessons are often more attractive for students and often lead them to become more active outside．

Attention deficit hyperactivity disorder（ADHD）（注意力缺失症）．Exposure to ordinary natural settings in the course of common after­school and weekend activities may be effective in reducing attention deficit symptoms in children．Participation in green activities—such as nature walks—helped ADHD patients from a wide range of backgrounds to stay focused and complete tasks．

Stress．Access to nature，even houseplants，can help children cope with stress．

Depression and seasonal emotional disorder．Major depression requires medical treatment，but physical activity，especially outdoors，can help ease symptoms．For your average case of winter blues，experts suggest spending time outside every day and，if possible，taking the family to a sunny vacation spot in mid­winter．

Experts emphasize that you needn't go to wilderness preserves to enjoy nature's benefits—simply walking in a city park or growing in a rooftop garden can make a difference．

Microsoft founder  Bill Gates said that he planned to give away almost all of his fortune(财富)，largely to the cause of global health，during the course of his lifetime.With an estimated(估计)worth of more than $40 billion，according to Forbes，the project will be no small fate(功绩) for Gates.Having already provided the Bill & Melinda Gates Foundation with $24 billion to address global health issues，Gates said that finally his entire fortune will be put towards the cause except “a few percent left for the kids”.
So what has made the richest man in the world to channel his resources so heavily into one interest？Gates believes that “the equality of opportunity（机会）”in which Americans take such pride needs to extend to other nations around the world. Improving the health of the populations，he says，has proven to be an essential method in helping poor countries to be financially successful.“National borders allow inequalities，”said Gates.“We all need  to take a more global view，rather than just saying my country is doing well.We have to step up these health issues，knowing how few resources are going into them.”
Gates said that both his parents set up an example for him as a child.His father，William H．Gates，was the head of the local Planned Parenthood，and his mother，Mary，volunteered for the United Way.As he gathered his fortune，Gates knew he would finally want to give back as well，but he didn’t expect to devote himself whole?heartedly to one project until he was about 60.
However，Gates,47，began to question his ability to wait that long.“It seemed there was a real time urgency，”Gates said.“I started to think how many lives I could save before then.”
