1 . South Korea has the highest rate of Internet addiction in the world and it is increasingly the country’s children who are spending every waking moment immersing themselves in fantasy role plays or gaming. In the remote mountains of South Korea, teenage Internet addicts are turning up for a 12-day boot camp.
Kyle Won’s addiction is out of control. He spends 10 hours a day on the Internet. Now Kyle’s smartphone is taken away. The teachers here do what they can to get them socializing again; for many, the only friends they have had are online. “I have relationships on the Internet and a real distance has grown with my real-life friends and I know it’s not good,” Kyle said. The teachers show them other possibilities and bring back dreams and hopes that have been buried by their addictions. “We teach them methods of managing their desire to use the Internet so that they can continue to use it when they go back home,” Shim Yong-chool, a teacher here, said. After just two days Kyle said it was helpful. He’s set a good example to others though he hasn’t reached the goal completely.
South Korean psychiatrists (精神病专家) are urging more action as they are finding evidence that too much screen time is a barrier to the developing minds. Professor Kang Seak Young from Dankook University said the addiction was damaging critical thinking. “It affects the frontal lobes (额叶) which are important to critical analysis,” Professor Kang said. “Reading a book and guessing what happens in the story next show activity in frontal lobes but playing popular computer games for a long time shows no activity.”
South Korea is one of the most wired nations on Earth, but it does have a cost. One in every ten kids is an addict, so the country is now learning how to manage its high-tech future to avoid more serious consequences.

2 . My Biggest Challenge
As a writer on an adventure sports magazine, I’d always fought shy of doing the adventurous stuff myself, preferring instead to observe the experts from a safe distance and relay their experiences to readers in the form of written language. Thus, when I was challenged to take part in a mountain climb in aid of raising money for charity — and to write about it afterwards — I was unwilling, to say the least.
I was lucky enough to have a brilliant climbing coach called Keith, who put me through my paces after my daily work. He gave me knowledge about everything from the importance of building muscle groups to how to avoid tiredness through nutrition. It quickly became apparent that the mechanics of climbing were more complex than I had imagined. There was the equipment and techniques I’d never even heard of, all of which would come in handy on the snow-capped peak I’d be climbing.
Aware of the challenge, Keith made a detailed action plan and I forced myself to stick to it, doing a daily workout at the gym and going on hikes with a heavy pack. I perfected my technique on the climbing wall and even went to climb the mountains to get vital experience. My self-belief increased alongside my muscle power and I became confident about finishing the climb.
All too soon I was on a plane to my destination. On that day, when I looked up at the mountain, I thought of abandoning it. But then I remembered all the hard work I’d done and how disappointed Keith would be if I gave up at the last minute-not to mention letting down the charity and the sense of failure I’d experience myself. With a deep breath I gathered my equipment and headed out into the sunshine to meet the rest of the group.
And as I sit here now, tapping away on my laptop, I’m amazed at the details in which I can recall every second of the climb: the burning muscles, the tiredness, the minor problems along the way. Could I have been better prepared? Possibly. Would I be back for another go? Thankfully not. The feeling of being excited when I stood on top of the world is a never-to-be-repeated experience but one I will enjoy forever nevertheless.

3 . The idea of billions of people going through a few masks a week during this pandemic definitely rings alarm bells, but a team of researchers in Melbourne may have the solution.
They’ve discovered that adding millions of discarded face masks to road-paving (铺路) mixtures would actually lower the cost of the road, while preventing billions of them from landfills. Just one kilometer of road would need three million masks, and the polypropylene (聚丙烯) plastic used to make single-use surgical face masks also increased the flexibility and durability of the road.
The new material is a mixture of about 2% torn masks, with recycled concrete aggregate (RCA)—a material obtained from waste concrete and other minerals from destroyed buildings. This recycled material was found in the study to be ideal for two of the four layers generally required to create roadways. Paving a kilometer of two-way road with the RCA and three million face masks would result in a change of 93 tons of waste from landfills.
The final product then is more resistant to wear than asphalt (沥青), as well as being cheaper too, provided there was a method for collecting masks. The research team did a cost-analysis and found that, at $26 per ton, the RCA was about half the cost of mining raw materials, and as much as a third of the cost of shipping the used masks to a landfill.
The widespread application would be ideal for large infrastructure (基础设施) projects. For example, Washington has the 11th worst roads in terms of unaddressed repairs in the U.S. If the damaged roads in Washington state were repaired with the RCA/mask mixture, it would reuse nearly 10 billion masks, sparing American landfills hundreds of millions of tons of trash.
It’s said that the team is looking for private industry partners or governments willing to give their plastic mask road an opportunity for a large-scale test.

4 . Have you ever loved a destination but couldn’t figure out why — or even a way ——to express your feelings? That’s my dilemma with Morocco.
In August, I traveled in a country that had long been, on my wish list. I rode a camel, got lost in Medinas, and ate more couscous (粗麦粉) than was humanly possible.
I loved the trip. Our friendly guide introduced us to the helpful locals. I made friends with my tour mates and my roommate (which, on a tour, is a huge blessing). I loved being lost in the smell of different spices, and the chaos of millions of people and the dark red of the Sahara were all I wanted them to be.
There were many moments when I felt like a fish out of water and things didn’t go my way. But I take pleasure in those moments because it’s when you are pushed out of your comfort zone that you grow. Morocco lived up to all my expectations, but for some reason, my experience has been hard to express. Why?
One constant in my travels is that of a touchstone, one defining point where the trip all comes together and acts as a prism (三棱镜) for everything the journey represented . In Costa Rica，it was getting lost in a jungle. In Thailand, it was meeting those five people who changed my life.
I’m so inconsistent about Morocco because I lack that touchstone. There’s no “whoa” moment. But I have thousands of little ones - staring at a million stars in the blackness of the desert, discovering new foods with some amazing Australians on my tour, and befriending the fish sellers.

5 . An 85-year-old primary school constructed in 1935 in Shanghai has been lifted off the ground in its entirety and relocated using new technology called the “walking machine.” The project marks the first time this “walking machine” method has been used in Shanghai to relocate a historical building.
Urbanization（都市化）has continued to significantly threaten architectural heritage. In the capital Beijing, for instance, more than 1,000 acres of its historic hutongs and traditional courtyard homes were destroyed between 1990 and 2010.
In the early 2000s, cities including Nanjing and Bejjing-due to the critics’ protest about the loss of old neighborhoods-drew up long-term plans to preserve what was left of their historic sites, with protections introduced to safeguard buildings and restrict developers.
These conservation efforts have taken different forms. In Beijing, a near-ruined temple was transformed into a restaurant and gallery, while in Nanjing, a cinema from the 1930s was restored to its original form, with some additions providing it for modern use. In 2019, Shanghai welcomed Tank Shanghai, an arts center built in renovated（重修的）oil tanks.
“Relocation is not the first choice, but better than destroying,” said Lan, the Shanghai primary school’s project supervisor. “I’d rather not touch the historical buildings at all.” Building relocations he said however, are “a workable option.” “The central government is putting more emphasis on the protection of historical buildings. I’m happy to see that progress in recent years.”
Shanghai has arguably been China’s most progressive city when it comes to heritage preservation. The survival of a number of 1930s buildings and 19th-century “shikumen” （or “stone gate”） house have offered examples of how to give old buildings new life.
“We have to preserve the historical building no matter what, ” Lan said. “The relocation has challenges, but in general, it is cheaper than destroying and then rebuilding something in a new location.”
1. How did cities respond to the loss of historical sites?| A．They criticized the developers. | B．They rebuilt the historic hutongs. |
| C．They ended the significant threat. | D．They proposed the protection project. |
| A．All original form. | B．A new addition. | C．A cinema. | D．A temple. |

| C．Old Building Torn down for Modern Use | D．Historical Site “Walks” to New Life |
6 . At the beginning of my 8:00 a. m. class one Monday at my college, I cheerfully asked my students how their weekend had been. One young man said that his weekend had not been very good. He then proceeded to ask me why I always seemed to be so cheerful. His question reminded me of something I’d read somewhere before: “Every morning when you get up, you have a choice about how you want to approach life that day”, I said to the young man. “I choose to be cheerful”. “Let me give you an example”, I continued.
The other 60 students in the class ceased their chatter and began to listen to our conversation.
As soon as I got to my office, I called to ask for a tow truck(拖车). The secretary in the office asked me what had happened. “This is my lucky day”, I replied, smiling. “Your car breaks down and today is your lucky day?” She was puzzled. “What do you mean?”
“I live 17 miles from here”, I replied. “My car could have broken down anywhere along the freeway. It didn’t. Instead, it broke down in the perfect place: off the freeway, within walking distance of here. I’m still able to teach my class, and I’ve been able to arrange for the tow truck to meet me after class. If my car was meant to break down today, it couldn’t have been arranged in a more convenient fashion.” The secretary’s eyes opened wide, and then she smiled. I smiled back and headed for class. So ended my story to the students in my economics class.
I scanned the 60 faces in the lecture hall. Despite the early hour, no one seemed to be asleep. Somehow, my story had touched them. Or maybe it wasn’t the story at all. In fact, it had all started with a student’s observation that I was cheerful. A wise man once said: “Who you are speaks louder to me than anything you can say”. I suppose it must be so.

7 . As more and more people speak the global language of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will be likely to die out by the next century, according the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations — UNESCO and National Geographic among them — have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following in that tradition. His recently published book, A Grammar of Thangmi and Their Culture, grows out of his experience living, working, and raising a family in a village in Nepal.
Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials —including photographs, films, tape recordings, and field notes — which had remained unstudied and were badly in need of care and protection. Now, through the two organizations that he has founded — the Digital Himalaya Project and the World Oral Literature Project — Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to schools but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

8 . Technology use seems to be the new wave of addiction hitting people of all ages. Its extreme use can be compared to the use of drugs, which is called Plug-in Heroin.
The next time you’re in a crowded public place, look at the people around you. It’s hard to find someone who isn’t glued to the tiny screen, fingers moving at lightning speeds, texting their friends, e-mailing coworkers or listening to music. It may seem ridiculous that someone is that addicted to such a small object. I’ve seen people who seem to be at their wits’ end if their phone or iPad has been taken away, lost or left at home.
Some people may ask, “What’s wrong with technology use? It’s a way for people to communicate.” While this is true, the overuse of technology isn’t always appropriate in certain settings. Schools are becoming stricter about the use of cell phones, iPods and other electronics in classrooms. Various workplaces have signs hanging on their walls warning employees that “Cell phone use is not permitted” or “Cell phones are forbidden”. On the first warning you will be sent home, and on the second warning you will be fired.
Electronics may be a way for people to communicate and stay in touch with each other, but the disadvantages may outweigh the benefits. People are losing the ability to hold face-to-face conversations with others. However, it’s hard to avoid electronics in this day and age because almost everything is turning into an electronic format. Books, originally meant for paper design, are now being transferred to electronic forms. Photo albums, and even yearbooks, can now be viewed via the Internet. With this growing trend, future generations are bound to become even more addicted to technology.
Is there a cure for electronic addiction? Simply turning electronics off for an hour or two a day may help to an extent, but it will not completely rid electronic addiction. There only seems to be one cure left, and it may be the hardest: self control.
1. What is Plug-in Heroin?| A．The growing popularity of electronics. |
| B．The serious consequences of technology use. |
| C．The future possibility of technology development. |
| D．The unreasonable dependence on electronics. |
| A．show people’s addiction to electronics. |
| B．persuade people to quit electronics. |
| C．prove electronics are harmful to people. |
| D．tell people it is ridiculous to use electronics. |
| A．People have no interest in traditional paper designs. |
| B．More information tends to be available in electronic forms. |
| C．It is the only way people stay in touch with each other. |
| D．People have fewer chances to communicate in person. |
| A．approving. | B．indifferent. | C．critical. | D．doubtful. |
9 . The beauty of the outdoors naturally encourages people to go outside. The drive toward the natural world is present in normal times. Now, as many people are locked indoors, spending hours in front of screens, the pull of watching wind blow branches of neighboring trees is hardly matched. Forest therapy is one way to satisfy the demand while improving personal health and well-being.
Inspired by the Japanese practice of shinrin-yoku, or "forest bathing", forest therapy is a guided outdoor practice, which encourages people to experience the pleasures of nature through all of their senses and be present in the body.
Research on shinrin-yoku began in Japan in the 1980s when leaders there noticed a sharp rise in stress-related illnesses in the country, resulting from people spending more time working in technology and other industrial work. Specific settings were created to guide people in outdoor experiences. Research showed forest bathing may help reduce stress, improve attention, and lift moods.
Stress raises levels of cortisol, which plays a role in high blood pressure, heart disease and headaches. In test subjects, levels of cortisol decreased after a walk in the forest. Trees give off oils called phytoncides that have special properties and may influence immunity(免疫力). Exposure to natural tree oils helps lift depression, lower blood pressure. One study showed a rise in the number and activity of immune cells, which fight viruses and cancer, among people who spent three days and two nights in a forest compared with people taking an urban trip. This benefit lasted for more than a month after the forest trip!
Don't worry if you don't have three days to spend in the forest. A recent study showed spending at least 120 minutes a week in nature improved self-reported health and well-being. It doesn't matter whether the 120 minutes represents one long trip, or several shorter visits to nature. So, even as we are honoring physical distancing, it's possible and essential to get outside for 20 minutes every day and enhance our well-being.

10 . With a quick movement, the little creature vanishes in the air like it never existed and somehow appears dramatically-this is a part of the film Fantastic Beasts and Where to Find Them. But in reality, “disappeared” fantastic creatures can also reappear.
The Global Wildlife Conservation(GWC) announced on Oct 30 they have rediscovered the Voeltzkow's chameleon(变色龙)in Madagascar. The last time that the animal was seen was in 1913.
This discovery excited the researeh team, but the finding was not easy. The GWC organized an expedition as part of its Seareh for Lost Species program, an attempt to rediscover species that have not been observed by scientists for at least a decade. They headed into the forests of northwestern Madagascar in April 2018. But they didn't have much luck for a long time. Just days before the trip was to end. the tour guides spotted one of the chameleons. Ultimately, the team discovered three males and 13 females.
Male Voeltzkow's chameleons are up to 164 millimeters long and are light green with dark stripes, which get darker when they are angry or stressed. Females are smaller than males, growing to about 150 millimeters long. They can change their skin to a pattern of red dots and a stripe of purple against a background of black and white.
“The Voeltzkow's chameleon adds color and beauty to the planet, and reminds us that even when all seems lost, a great adventure can reawaken hope." said Don Church, president of the GWC. "Now we have so much to learn about this extraordinary reptile(爬行动物)・including how we can best save it from extinction.”
This isn't the only time a species thought to be extinct has been rediscovered. In fact, this year scientists discovered a frog that has been missing for more than 50 years in a Brazilian jungle. Another example is the Albany adder snake, which was rediscovered in 2016. The species had disappeared for over a decade and was generally believed to be extinct.
So how are these "lost" species able to make a comeback? If the environment changes in favor of certain species that have been considered extinct, the population size of those species may recover again. As they reach greater numbers, the chance of humans discovering them increases.
