Caught in the Web
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 intervals. Her household bills piled up, along with the dishes and dirty laundry, but it took near-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
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 excessive Internet use. The American Psychiatric Association may consider listing Internet addiction in the next edition of its diagnostic manual. And scores of online discussion boards have popped up on which people discuss negative experiences tied to too much time on the Web.
"There's no question that there're people who're seriously in trouble because they're overdoing their Internet involvement," said psychiatrist (精神科医生) Ivan Goldberg. Goldberg calls the problem a disorder rather than a true addiction.
Jonathan Bishop, a researcher in
The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the 2005 survey, this one was conducted by
About 8% said they used the Internet as a way to escape problems, and almost 14% reported they "found it hard to stay away from the Internet for several days at a time."
"The Internet problem is still in its infancy," said Elias Aboujaoude, a Stanford 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, a
Since the early 1990s, several clinics have been established in the
The website for Orzack's center lists the following among the psychological symptoms of computer addiction:
● Having a sense of well-being (幸福) or excitement while at the computer.
● Longing for more and more time at the computer.
● Neglect of family and friends.
● Feeling empty, depressed 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 excessive Internet use 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 mortgage (抵押贷款) 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."

Passage One
Questions 57 to 61 are based on the following passage.
You never see him, but they're with you every time you fly. They record where you are going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to

Passage Two
Questions 62 to 66 are based on the following passage.
The $11 billion self-help industry is built on the idea that you should turn negative thoughts like "I never do anything right" into positive ones like "I can succeed." But was positive thinking advocate Norman Vincent Peale right? Is there power in positive thinking?
Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply highlight how unhappy they are.
The study's authors, Joanne Wood and John Lee of the
In this experiment, Wood, Lee and Perunovic measured 68 students' self-esteem. The participants were then asked to write down their thoughts and feelings for four minutes. Every 15 seconds, one group of students heard a bell. When it rang, they were supposed to tell themselves, "I am lovable."
Those with low self-esteem didn't feel better after the forced self-affirmation. In fact, their moods turned significantly darker than those of members of the control group, who weren't urged to think positive thoughts.
The paper provides support for newer forms of psychotherapy (心理治疗) that urge people to accept their negative thoughts and feelings rather than fight them. In the fighting, we not only often fail but can make things worse. Meditation (静思) techniques, in contrast, can teach people to put their shortcomings into a larger, more realistic perspective. Call it the power of negative thinking.

Due Attention Should Be Given To Spelling
Correct spelling is a basic skill in English study. However, nowadays many students do not pay much attention to it.
They have their own reasons for misspelling. First of all, they like an easy way of studying, which causes some omissions and changes in spelling. Second, the teachers might not be very strict in students’ spelling. In China, teachers seem to be more concerned with grammar and vocabulary but not spelling.
To change this situation, in my opinion, the teachers and the students should work together. On one and, the teachers should give more attention to students’ spelling, asking the students to be conscious of the importance of correct spelling from the very beginning of their English study. On the other hand, the students themselves are supposed to be aware that correct spelling is a must in English study.
To sum up, correct spelling is so important that both students and the teachers should spare no efforts to achieve correct spelling.
