　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."

What eventually made Carla Toebe realize she was spending too much time on the Internet?

　A. Her daughter's repeated complaints.

　B. Tiredness resulting from lack of sleep.

　C. The poorly managed state of her house.

　D. The high financial costs adding up.

What is the main idea of para4?

A. A study claimed to be the first large-scale look at Internet overuse.

B. The American Psychiatric Association plans to list Internet addiction in its edition.

C. There are heated discussions about negative experiences over internet overuse.

D. There is a growing concern towards internet addiction.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
　【小题1】　
Today，kids have more worries and face more pressures than ever before. Here are a few tips to help your child focus on and do well in school.
●Create a personal schedule
Recording everything that must be done on a calendar or “to do” list will help him to keep track of important dates and deadlines. If he keeps it in a visible place he will have no problem acknowledging upcoming events and will be better able to plan how and where to spend his time.
●Watch the clock
　【小题2】　 I also recommend setting his clock or watch five minutes ahead since it's always easy to run late. When it comes to something like catching a bus，just five minutes can make a significant difference.
●Focus
He should train himself to be able to concentrate alone on one specific task. This is much easier in a noise­free environment. No TV or radio should be on to distract him.
●　【小题3】　
Lack of sleep is proven to harm us physically. The more sleep we get，the more alert we are. We thus have more energy to handle life's daily tasks. The average adult needs at least six hours of sleep a night and the average child needs at least eight.
●Stay in shape
Through spending time outdoors or playing sports with friends，he can “blow off some steam” so to speak，as well as re­energize.　【小题4】　
●Talk through your problems
Be able to share his concerns with you. 　【小题5】　 If you make it clear that you understand him and are willing to help，not only will you contribute to his emotional health but you'll help build an open and honest relationship as well.

A．Sharing feelings often makes them easier to deal with.

B．Help your child work better to realize his aim.

C．Setting an alarm for the morning is a must.

D．Get enough sleep.

E．Help your child do better in school.
F．Encourage your child to be positive.
