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 happin
ess 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. |

| A．Humorous | B．Ironic | C．Objective | D．Casual |
Machu Picchu is considered to be a truly extraordinary archaeological(考古学的) discovery and is one of South America’s largest tourist sites. As many as one thousand visitors visit the ancient Incan（印加文化的） ruins daily. What draws vacationers and adventurers to this remote location high in the Andes Mountains of Peru（秘鲁）? A large part of the attraction is the mysteries that surround Machu Picchu. For example, Machu Picchu is considered “the lost city” of the Incas because it was never found by Spanish invaders and was known to only a few local peasants for almost four hundred years.
The “city in the clouds”, Machu Picchu’s lasting beauty comes from the careful blending of its striking architecture with its mountaintop environment. Its greatest skill shows are in the stone structures, which equals that of the ancient Egyptians. The stone blocks were so appropriately cut that they fit together without the need for mud. The largest stones at Machu Picchu weigh as much as fifteen tons! It has been difficult to explain how the huge blocks were transported. The buildings, including many that have survived lots of earthquakes, contain stones which interlock so perfectly that a knife cannot be forced between them. When compared to other ancient civilizations, it is difficult to understand how Machu Picchu could have been missed by the Spanish and lost from history for four hundred years.
For many of the mysteries of Machu Picchu being unsolved, it is clear why Machu Picchu remains “the most famous ruins in all of South America”. Which of the followings is NOT a mystery of Machu Picchu?
| A．Machu Picchu is called the “city in the clouds”. |
| B．Machu Picchu remains “the most famous ruins of South America”. |
| C．Machu Picchu is “the lost city” of the Incas. |
| D．Machu Picchu is the largest stone city of the world. |
The underlined word “interlock” probably means _________

The purpose of writing the passage is to __________.
| A．ask us to pay a visit to Machu Picchu |
| B．show us the beauty of Machu Picchu |
| C．introduce Machu Picchu’s mysteries |
| D．make the ancient Incan ruins known |
There once lived a rich businessman who had a lazy son. The businessman wanted his son to realize the value of labour and said: “Today, I want you to go out and earn something, failing which you won’t have your meals tonight.”
He went crying straight to his mother. Her heart melted at her son’s eyes. She gave him a gold coin. When the father asked his son what he had earned, the son presented him the gold coin. The father asked him to throw it into a well.
The next day, he asked his son to earn something. This time he went crying to his sister who gave him a coin. When he showed it to his father he again asked him to throw it in a well. Then the father asked him to earn more money.
This time since there was no one to help him, the son was forced to go to the market. One shopkeeper told him he would pay him two coins if he carried his trunk to his house. He did so and sweated plenty. As he returned home he was asked to do the same. The son almost cried out. He could not imagine throwing his hard-earned money like this. He cried, “My entire body is aching. You are asking me to throw the money into the well.”
At this moment, the businessman told him one feels the pain only when the fruits of hard labour are wasted. On the earlier two occasions he was helped and therefore had no pain in throwing the coins into the well. The son had now realized the value of hard work. He promised never to be lazy and to safely keep the father’s wealth. The father handed over the keys of his shop to the son and promised to guide him through the rest of the life.Which of the following is TRUE?

Plants are flowering faster than scientists predicted（预测）in reaction to climate change, which could have long damaging effects on food chains and ecosystems.
Global warming is having a great effect on hundreds of plant and animal species around the world, changing some living patterns, scientists say.
Increased carbon dioxide（CO2）in the air from burning coal and oil can have an effect on how plants produce oxygen, while higher temperatures and changeable rainfall patterns can change their patterns of growth.
“Predicting species’ reaction to climate change is a major challenge in ecology,” said the researches of several U.S. universities. They said plants had been the key object of study because their reaction to climate change could have an effect on food chains and ecosystem services.
The study, published on the Nature website, uses the findings from plant life cycle studies and experiments across four continents and 1,634 species. It found that some experiments had underestimated（低估）the speed of flowering by 8.5 times and leafing by 4 times.
“Across all species, the experiments under-predicted the speed of the advance — for both leafing and flowering — that results from temperature increases,” the study said.
The design of future experiments may need to be improved to better predict how plants will react to climate change, it said.
Plants are necessary for life on the Earth. They are the base of the food chain, using photosynthesis（光合作用）to produce sugar from carbon dioxide and water. They let out oxygen which is needed by nearly every organism on the planet.
Scientists believe the world’s average temperature has risen by about 0.8℃ since 1900, and nearly 0.2℃ every ten years since 1979.
So far, efforts to cut emissions（排放）of planet-warming greenhouse gases are not seen as enough to prevent the Earth heating up beyond 2℃ this century — a point scientists say will bring the danger of a changeable climate in which weather extremes are common, leading to drought, floods, crop failures and rising sea levels.What is the key information the author wants to give in Paragraph 1?
| A．Plants’ reaction to weather could have damaging effects on ecosystem. |
| B．The increasing speed of flowering is beyond scientists’ expectation. |
| C．Climate change leads to the change of food production patterns. |
| D．Food chains have been seriously damaged because of weather. |
We can learn from the study published on the Nature website that ______.
| A．plants’ flowering is 8.5 times faster than leafing |
| B．there are 1,634 plant species on the four continents |
| C．scientists should improve the design of the experiments |
| D．the experiments failed to predict how plants react to climate change |
Scientists pay special attention to the study of plants because _______.
| A．they can prove the climate change clearly |
| B．they are very important in the food chains |
| C．they play a leading role in reducing global warming |
| D．they are growing and flowering much faster than before |
What can be inferred from the last two paragraphs about the world’s temperature?
| A．It has risen nearly 0.2℃ since 1979. |
| B．Its change will lead to weather extremes. |
| C．It is 0.8℃ higher in 1979 than that of 1990. |
| D．It needs to be controlled within 2℃ in this century. |
In a recent announcement, Harvard and the Massachusetts Institute of Technology（MIT）said that they have joined forces to offer free online courses in an effort to attract millions of online learners worldwide.
Beginning this fall, a number of courses developed by teachers at both universities will be offered online through a new $60 million program, known as edX. “Anyone with an Internet connection anywhere in the world can use our online courses,” Harvard President Drew Faust said during a meeting to announce the plan.
MIT has offered a program called OpenCourseWare for ten years that makes materials from more than 2,000 classes free online. It has been used by more than 100 million people. In December, the school announced it also would begin offering a special certificate, known as MITx, for people who complete certain online courses. Harvard has long offered courses to a wider population through a similar program.
The MITx will serve as the foundation for the new learning platform.
MIT President Susan Hockfield said more than 120,000 people signed up for the first MITx course. She said Harvard and MIT hope other universities will join them in offering courses on the open-source edX platform.
“Fasten your seatbelts,” Hockfield said.
Other universities, including Stanford, Yale and Carnegie-Mellon, have been experimenting with teaching to a global population online.
The Harvard-MIT program will be monitored by a not-for-profit（非盈利的）organization based in Cambridge, to be owned equally by the two universities. Both MIT and Harvard have provided $30 million to start the program. They also plan to use the edX platform to research how students learn and which teaching methods and tools are most successful.According to this text, edX is _______.
| A．a part of the free MIT OpenCourseWare |
| B．a free computer program by MIT and Harvard |
| C．a Harvard-MIT platform of free online courses |
| D．a free program online for universities worldwide |
What is said about online education in the text?
| A．Universities have been trying online courses. |
| B．About 2,000 online courses have been offered. |
| C．Over 100 million people have finished courses online. |

I left university with a good degree in English Literature, but no sense of what I wanted to do. Over the next six years, I was treading water, just trying to earn an income. I tried journalism, but I didn’t think I was any good, then finance, which I hated. Finally, I got a job as a rights assistant at a famous publisher. I loved working with books, although the job that I did was dull.
I had enough savings to take a year off work, and I decided to try to satisfy a deep-down wish to write a novel. Attending a Novel Writing MA course gave me the structure I needed to write my first 55,000 words.
It takes confidence to make a new start — there’s a dark period in-between where you’re neither one thing nor the other. You’re out for dinner and people ask what you do, and you’re too ashamed to say, “Well, I’m writing a novel, but I’m not quite sure if I’m going to get there.” My confidence dived. Believing my novel could not be published, I put it aside.
Then I met an agent（代理商）who said I should send my novel out to agents. So, I did and, to my surprise, got some wonderful feedback. I felt a little hope that I might actually become a published writer and, after signing with an agent, I finished the second half of the novel.
The next problem was finding a publisher. After two-and-a-half years of no income, just waiting and wondering, a publisher offered me a book deal — that publisher turned out to be the one I once worked for.
It feels like an unbelievable stroke of luck — of fate, really. When you set out to do something different, there’s no end in sight, so to find myself in a position where I now have my own name on a contract（合同）of the publisher — to be a published writer — is unbelievably rewarding（有回报的）.What does the underlined part in Paragraph 1 mean?
| A．I was waiting for good fortune. |
| B．I was trying to find an admirable job. |
| C．I was being aimless about a suitable job. |
| D．I was doing several jobs for more pay at a time. |
The author decided to write a novel ______ .
| A．to finish the writing course |
| B．to realize her own dream |
| C．to satisfy readers’ wish |
| D．to earn more money |
How did the writer feel halfway with the novel?
| A．Disturbed. | B．Ashamed. | C．Confident. | D．Uncertain. |
What does the author mainly want to tell readers in the last paragraph?
| A．It pays to stick to one’s goal. |
| B．Hard work can lead to success. |
| C．She feels like being unexpectedly lucky. |
| D．There is no end in sight when starting to do something. |
