About one in ten video game players shows signs of addictive behavior that could have negative effects on their family, friends and school work, according to a new study conducted in New York.
Researchers at Iowa State University(ISU) and the National Institute on Media and the Family found that some gamers show at least six symptoms of gambling addiction such as lying to family and friends about how much they play games, using the games to escape their problems and becoming restless when they stop playing.
They may also skip homework to play video games or spend too much time playing games and do poorly in school. “While the medical community currently does not recognize video game addiction as mental disorder, hopefully this study will be one of many that allow us to have an educated conversation on the positive and negative effects of video games,” said Dr Douglas Gentile, an assistant professor of psychology at ISU.
Dr David Walsh, the president of the National Institute on Media and the Family which tries to reduce the harm of media on the health and development of children and families, said the findings are a wake-up call.“This study gives everyone a better idea of the problem,” he explained.
The researchers, who studied 1,178 American children and teenagers, aged 8 to 18, found some displayed at least 6 of 11 symptoms of pathological (病态的) gambling as stated by the American Psychiatric Association. Addicted gamers played video games 24 hours a week, twice as much as casual gamers. Some addicted gamers even steal to support their habit, according to the findings that will be published in the journal Psychological Science.
While video games can be fun and entertaining, some kids are getting trouble. “I continue to hear from families who are concerned about their kids’ gaming habits. Not only do we need to focus on identifying the problem, but we need to find ways to help families prevent and treat gaming addiction.

【推荐1】The Japanese have always been at the forefront at deploying (利用) robots to perform jobs that are traditionally done by humans. Over the past year, humanoid robots have been seen helping customers at the Mitsubishi Bank and even filling in for human science communicators at museums. Therefore, it is not surprising to hear that the country has the worlds first hotel that is staffed almost entirely by the Androids!
The aptly (巧妙地) named Henn-na (“strange” in Japanese) Hotel which opened its doors on July 17 is located at Nagasaki’s Huis Ten Bosch theme park. It is the idea of Hideo Sawada, a Japanese businessman who is fascinated by the possibility of replacing humans with robots. His aim is to have this futuristic hotel be run mainly by the intelligent humanoids.
Guests checking-in are welcomed by a family friendly English-speaking robot wearing a bow tie and bell-hop (侍者) hat. Though experienced at his job, he does request guests not to ask him “a difficult question” since he is after all, “just a robot!” Those seeking a more “regular” experience, can approach the human-like Japanese-speaking robot.
When ready, visitors can request the robot “porters” to help carry belongings to their room. Those that need to stow away valuables can hand them to a helpful robot who will place them inside an individual safe box in exchange for a small fee. A one-foot-high concierge (管理人) is available to provide information about the hotel’s amenities (便利设施), nearby attractions, and even order a taxi if needed.
So how much does it cost to live in this crazy cool hotel? It depends on when you decide to go. During the low season, guests can get away with paying as little $60 a night for a basic room. However, during the peak season when rates, are determined by an online auction, the price can get as high as $153.

【推荐2】People now have access to more information than ever before thanks to the Internet. While there are clearly benefits to it, there are also unexpected effects. One in particular is information overload, commonly referred to as “inf-obesity”.
Inf-obesity can be caused by many factors. For example, information from various sources can lead to inf-obesity. A search on a particular topic can bring hundreds of websites with a lot of information, and you may feel very upset due to the amount of information accessible.
So, what can be done to reduce the effects of this condition? While there is no easy answer, one obvious step is to limit our sources of information. Sort the information we receive as important and unimportant, and try to only focus on things that really matter to us and on just one thing at a time.
Too much of anything is bad.
| A．This applies not only to the food one consumes |
| B．Experts have shown some major effects of inf-obesity |
| C．This would give us more room to absorb information from sources |
| D．Being constantly connected to technology can also result in inf-obesity |
| E．It involves a situation where there’s too much information on a given topic |
| F．We are sure about how certain types of information help us get where we want to go |
| G．One example is that, for online shoppers, a purchase can be difficult with so many choices accessible |
【推荐3】Across the rich world, well-educated people increasingly work longer than the less-skilled. Some 65% of American men aged 62 - 74 with a professional degree are in the workforce, compared with 32% of men with only a high-school certificate. This gap is part of a deepening divide between the well-educated well-off and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound (深刻的).
The world is facing an astonishing rise in the number of old people, and they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity translated into more years in retirement rather than more years at work, has persuaded many observers that this shift will lead to slower economic growth, while the swelling (扩大的) ranks of pensioners (领养老金者) will create government budget problems.
But the notion of a sharp division between the working young and the idle (不工作的) old misses a new trend, the growing gap between the skilled and the unskilled. Employment rates are falling among younger unskilled people, whereas older skilled folk are working longer. The divide is most extreme in America, where well-educated baby-boomers are putting off retirement while many less-skilled younger people have dropped out of the workforce.
Policy is partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated. Technological change may well reinforce (加强) that shift: the skills that complement (补充) computers, from management to creativity, do not necessarily decline with age.

【推荐1】The practice of drinking tea has a long history in China. According to a popular story. tea was discovered by Shennong in 2737 BC when a leaf from a nearby shrub（灌木）fell into the water Shennong was boiling. Tea is deeply woven into the history and culture of China.
The Chinese have a saying: “Firewood, rice, oil, salt, sauce, vinegar and tea are the seven necessities to begin a day.” Though tea is the last on the list, we still can see its importance in daily life. A simple meal in Chinese is Cu Cha Dan Fan, which shows even a simple meal is finished with tea.
For the Chinese, tea drinking and tasting are not parallel. Tea drinking can help keep up one’s spirit while tea tasting has cultural meaning. Tea and tea sets should match the breeze, the bright moon, bamboo and so on. All these show the goal of Chinese culture: the harmonious（和谐的）unity of human beings with nature.
Similarly, tea-drinking habits differ in different parts of China. Generally. flowering tea is popular in northern China; green tea is preferred in eastern China, and black tea is fit for people in Fujian and Guangdong. Green tea is the most popular type of tea drunk in China. Green tea usually loses its flavor（味道）within a year while the flavor of black tea can remain for several years. As a result, black tea has long been traded worldwide. It still accounts for over ninety percent of all tea sold in the West. At present, tea is commonly seen in Chinese restaurants and grocery shops worldwide.

【推荐2】The cost of living in countries like the U.S., Britain, Australia or France has skyrocketed in recent years. However, if you are willing to leave your country and explore life in other areas, there are many countries boasting an extremely cheap and low cost of living. Check out the following countries when planning your next move.
Ecuador
Ecuador is similar to the United States in many ways, and as a result has become a popular American getaway. It even uses the U.S. dollar for its currency. In this country, it is cheaper to eat out every day than cook for yourself on a budget in the U.S. You can even buy a property for around $50,000 and hi re someone to tend to it while you are away.
Mexico
Although the country is known for its poverty-ridden streets, there are many wealthier areas that provide every facility you might need. You can live off a mere $700 to $800 a month in Mexico, and this includes rent for a nice place, facilities, food, and any sightseeing.
Argentina
Argentina has been a popular tourist destination for many years. It has great restaurants, a rich history, and many places to explore. Not to mention, it is not very expensive to live there. A decent-sized home can cost around $139,000, which is relatively cheap in relation to homes in the United States.
Vietnam
Vietnam has also become a popular tourist destination in recent years. There are many million-dollar luxury homes by the beach, but you can find a modest flat or small home for around $25,000 to $50,000 if you search in the right areas.

【推荐3】Recently, as a journalist, I have published many stories about social media, privacy and artificial intelligence (AI), among other things. So when ChatGPT told me that my output may have influenced its responses to other people’s prompts (提示), I rushed to wipe my data from its memory. As I quickly discovered, however, there is no delete button. AI-powered chatbots never forget what they have learned, because they are trained on data sets including vast numbers of websites and online articles. As long as they exist on the Internet, they get to be remembered.
That means the likes of ChatGPT are possible to let out sensitive personal information, if it has appeared online, and that the companies behind these AIs will struggle to make good on “right-to-be-forgotten” regulations, which force organizations to remove personal data on request. It also means we are powerless to stop hackers (黑客) controlling AI outputs by planting misinformation or ill instructions in training data. All of these explain why many computer scientists are busy to teach AIs to forget. While they are finding that it is extremely difficult, “machine unlearning” solutions are beginning to appear. And the work could prove vital beyond addressing concerns over privacy and misinformation.
The new generation of AI-powered chatbots like ChatGPT, which produce text in response to our prompts, are underpinned by large language models. These are trained on mountains of data, most of which is scraped from the Internet. From this, they learn to spot statistical patterns, which means they can predict the likeliest next word in a sentence, producing fluent answers to our every question.
The trouble is that the way AI chatbots work means that when they learn something, it can’t be unlearned. This creates a significant problem when it comes to privacy, as Dr. Zhang made clear in recent research. He highlighted how difficult it will be for AI companies to obey the “right to be forgotten”, which the European Union declared a human right back in 2014.
1. Why can chatbots store what it has learned forever?| A．Lack of a delete button. | B．Manual code entry. |
| C．Strong review ability. | D．The way they are trained. |
| A．Because AI has many security risks. | B．Because AI stores limited information. |
| C．Because AI needs to be updated regularly. | D．Because AI imitates humans completely. |
| A．Chatbots can answer 90% of the questions. |
| B．Chatbots’ data comes from the designer’s software. |
| C．Chatbots produce the answers based on the prompts. |
| D．Chatbots can predict your problems in advance. |

【推荐1】The World’s Unusual Libraries
Log Libraries
Alex Johnson writes in his new book—Improbable Libraries,“ The very idea of a library is developing:many of these libraries operate on principles that differ mainly from the traditional libraries. Some, for example, have no membership or identification requirements, and some do not even request that the books be returned.” The oversized bird box in a park in Lowa is part of the Little Free Library Movement, which was established in Wisconsin in 2009.
Phone Booths
This design from the firm, Stereotank, offers browsing shelter for passers-by. In the UK, a phone company’s programme, allowing communities to take over their phone booth for £ 1— means that many have been changed into tiny local libraries. Meanwhile , a solar light has been set in a phone booth so that late night visitors can still read.
Branches of Knowledge
Didier Muller’s libraries operate as hanging libraries: visitors can look through pages, taking any book they choose and exchanging it with their own. The equipment of hanging wooden houses is one of several art projects serving as a booklover’ s place.
Soundproofed Pods
Around the world, architects are designing buildings that bend bricks-and-mortar libraries into new forms. The Seikei University Library in Japan—the vision of Pritzker Prize winner Shigeru Ban—contains space-age soundproofed (隔音的) pods to encourage discussions between students.

【推荐1】It's school time again! You're probably feeling excited and maybe a little sad that summer vacation is over.
Some kids feel nervous or a little scared on the first day of school because of all the new things: new teachers, new friends, and even a new school. Luckily, these “new” worries only stick around for a little while. Let’s find out more about going to a new school.
Most teachers kick off the new school year by introducing themselves and talking about all the things you’ll be doing that year. Some teachers give students chance to tell something about themselves to the rest of the class.
When teachers do the talking on the first day, they often go over the classroom rules and school rules so you will know what’s allowed and what’s not. Please pay close attention.
You might already know a lot of people in your class on the first day, but it's a great day to make a new friend, so try to say hello to kids you know and new ones that you don't. Make the first move and you will be glad about what you did, and so will your new friends!
Seeing friends you haven't seen in a while can make the first day a good one. You can make the day special by wearing clothes that you really like. Maybe you got a great T-shirt on one of your vacations or a pair of sneakers. It can also make you feel good to be prepared and have all the things you need, such as pencils, folders，and whatever else you need. But make sure that you pack them the night before in case you don’t have time in the morning.

【推荐2】Some American National Parks
Theodore Roosevelt National Park
The 28th American president Theodore Roosevelt established the park to escape the reminder of his mother and wife, who died of illness on the same day. The park has three main areas -- the South Unit, the North Unit, and the Elkhorn Ranch（大农场） Unit. In the South Unit, visitors can drive along the Scenic Loop road. It offers many places to see wildlife and the surrounding badlands. Many visitors st op to look at Painted Canyon（峡谷）. Trails near the canyon offer visitors a chance to see animals, from the huge American bison to small black-tailed prairie dogs. The North Unit also offers several hiking trails. The third area of the park is what Roosevelt described as his "home ranch."
Olympic National Park
The park is located in the western state of Washington. It is on the Olympic Peninsula, in the northwest part of the state. The park covers more than 400,000 hectares. It has several different ecosystems. Visitors will find temperate rainforests, glacier-covered mountains, and almost 120 kilometers of wild coastline. Olympic National Park has meadows and lakes. It has glacier-fed rivers and mountain peaks that rise more than 2,300 meters. To protect the nature of the area, President Grover Cleveland declared the Olympic Peninsula's forests as the Olympic Forest Reserve in 1897. And in 1938, President Franklin Roosevelt signed the bill that established the Olympic National Park.
Voyageurs National Park
The state of Minnesota is known as the land of 10,000 lakes. Voyageurs National Park covers almost 88,500 hectares. About half of that surface is water. Much of the park is accessible only by boat. President Richard Nixon signed the bill that finally established Voyageurs as a national park in 1971. Nature and art meet at the Ellsworth Rock Gardens in the park. A carpenter and artist from Chicago named Jack Ellsworth built a summer home. He designed, built and created about 200 rock sculptures from native stone. Voyageurs National Park may be best seen at night. The most special light display on Earth is sometimes visible at Voyageurs.
Petrified Forest National Park
The word "forest" may mislead visitors. The park is in a desert. And the word "petrified" -- which can mean "afraid"-- may scare visitors away! But fear not. "Petrified Forest" gets its name from the trees that have, over millions of years, turned to stone. That natural process is called fossilization (化石化). The Petrified Forest National Park is one of the wonders of Arizona. The oldest geological formations in the park are about 227 million years old. Differently colored formations show different time periods. Long before humans entered the area, dinosaurs dominated. Petrified Forest National Park is a world-class area for fossil research.

【推荐3】Smartphones have been blamed for everything from taking drivers' attention from driving to keeping people on the sofa scrolling (滚屏) videos. But the smartphone that seems to be everywhere could just as easily increase physical activity if it pushes its owner's buttons in the right way.
New research shows that making social connections through activity-tracking apps gets people to move more. And a separate study on this summer’s “Pokemon Go” phenomenon shows that the smartphone game got players to take thousands more steps than usual. Together, the studies show the potential for smartphones to push a range of people to be more active.
People who linked with friends on the activity-tracking app increase their steps by 400 a day on average over the next week, compared with people who made no social connections, according to Tim Althoff and two other computer scientists at Stanford University. The effect of social connections declined, but remained significant for five months before the numbers fell back even with users who made no connections.
Such insights show the promise of smartphones and games to help with one of the most stubborn public health problems — that even people who want to be active have trouble staying active.
An NBA video game, for example, gives players extra powers in the game if they reach a step goal in real life. The app “Zomies, Run!” uses audio stories to push people to run more or run faster.
Still, there is room for growth: Only about 4% of all health apps use “gamification”, such as point-scoring or competition, according to a study published in October in BMJ Open. “Gamification is actually quite closely linked with behavior change techniques”, says Dr. Elizabeth Ann Edwards, the study's lead author and a doctor and researcher at Queen Mary University of London.
