　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."

　A. Her daughter's repeated complaints.

　　New Development for Central and Western China（开头）The Chinese government has recently decided to develop central and western China.

　　___________________________________________________________________________

　　___________________________________________________________________________

　　（结果） We have every reason to believe that the development will be a great success. As a result of the great project, central and western regions of China will surely achieve better and faster development in the new century. The people will have a better life and China will surely be richer and stronger.

I believe that families are not only blood relatives, but sometimes people who show up and love you when no one else will.

In May 1977, I was living in a Howard Johnson’s motel off Interstate 10 in Houston. My dad and I 21 a room with two double beds and a bathroom which was too 22 for a 15-year-old girl and her father. Dad’s second marriage was 　23 and my stepmother had 　24 us both out of the house the previous week. Dad had no　 25_ what to do with me. And that’s when my other family 　26 .

Barbara and Roland Beach took me into their home 　27　 their only daughter, Su, my best friend, asked them to. I 　28 with them for the next seven years.

Barb washed my skirts the same as Su’s. She 　29 I had lunch money, doctors’ appointments, help with homework and nightly hugs. Barbara and Roland attended every football game where Su and I were being cheerleaders. 30 I could tell, for the Beaches there was no 31 between Su and me; I was their daughter, too.

When Su and I 32 college they kept my room the same for the entire four years I attended school. Recently, Barb presented me with an insurance policy they bought when I first moved in with them and had continued to pay on for 23 years.

The Beaches knew 33 about me when they took me in – they had heard the whole story from Su. When I was seven, my mother died and from then on my father relied on other people to _34 his kids. Before I went to live with the Beaches I had believed that life was entirely 　35__ and that love was shaky and untrustworthy. I had believed that the only person who would take care of me was me.

36 the Beaches, I would have become a bitter, cynical (愤世嫉俗的) woman. They gave me a(n) 37 that allowed me to grow and change. They kept me from being paralyzed(使瘫痪 ,使麻痹 ,使无能力)by my _38　 , and they gave me the confidence to open my heart.

I 　39 family. For me, it wasn’t the family that was there on the day I was 　40　 , but the one that was there for me when I was living in a Howard Johnson’s on Interstate 10.
