Most students, when asked about their best graduation(毕业) gift, would probably reply, “ A car”, or “Money for a house”. Cai Kaiyuan, 21, made a difference choice. As a graduation gift to himself, he decided to work as a volunteer teacher in a distant village in Tibet.

    Cai, a student at Huan Railway Professional Technology College, at first planned to cycle from Sichuan to Tibet. It turned out cycling on a plateau(高原) was quite difficult. And it has kept changing his opinion on life. Cai's hands even became painful while cycling up a 5008-meter-high mountain, where temperatures often dropped to 18 below zero. At night, the ice covered the road and he fell off his bike three times. Little oxygen made him feel sick and weak. “At the most serious moment, I felt that was on the line,” said Cai.

    However, he also gained something unexpected. At Ya' an, a city in Sichuan, he met a group of tourists who are also university students. A girl called Wu Ling told him that she planned to work as a in a primary school in Tibet after her journey. He was impressed by the idea as she looked weak.

    It was not until he reached a family-run hotel in Shigatse that Cai's spirits began to rise. The hotel manager's two daughters enjoyed talking with him. The kids asked about his experiences on his trip, and showed him the beautiful local lakes. “They told me that they always liked to talk to guests, as they wanted to improve their Mandarin,” he said, “Their parents and many locals can only speak Tibetan.”

    Cai was moved by the girls' story. Their situation is worse and the local people have little chance to learn Mandarin because the schools are short of teacher. “1 want to do something to improve the situation for kids like them,” said Cai. His parents finally gave their agreement and his teachers also supported him.

    The past ages of man have all been carefully labeled by anthropologists (人类学家). Descriptions like "Palaeolithic (旧石器时代的) Man". "Neolithic (新石器时代的) Man",etc. neatly sum up whole periods. When the time comes for anthropologists to turn their attention to the twentieth century, they will surely choose the label "Legless Man". Histories of the time will go something like this: "in the twentieth century, people forgot how to use their legs. Men and women moved about in cars, buses and trains from a very early age. There were lifts in all large buildings to prevent people from walking. And the surprising thing is that they didn't use their legs even when they went on holiday."

    The future history books might also record that we were deprived (剥夺) of the use of our eyes. In our hurry to get from one place to another, we failed to see anything on the way. Air travel gives you a bird's-eye view of the world. When you travel by car or train, an unclear picture of the countryside constantly smears the windows. Car drivers, especially, are mixed with the urge to go on and on: they never want to stop. The typical twentieth-century traveler is the man who always says "I've been there." You mention the remotest, and someone is bound to say "I've been there"-meaning, "I drove through it at100 miles an hour on the way to somewhere else."

    When you travel at high speeds, the present means nothing: you live mainly in the future because you spend most of your time looking forward to arriving at some other place. But actual arrival, when it is achieved, is meaningless. You want to move on again. By traveling like this, you suspend all experience. The traveler on foot, on the other hand, lives constantly in the present. For him traveling and arriving are one and the same thing: he arrives somewhere with every step he makes. He experiences the present moment with his eyes, his ears and the whole of his body. At the end of his journey he feels a delicious physical tiredness. He knows that sound, satisfying sleep will be his: the just reward of all true travelers.

    Life for almost anyone is increasingly influenced by screens. Not only are screens themselves cheap to make, but they also make things cheaper. Any place that can fit a screen in can cut costs. And any activity that can happen on a screen becomes cheaper. The physical experience of learning, living and dying is becoming smooth glass. All of this has led to a curious new reality: Human contact is becoming a luxury good (奢侈品).

    "What we are seeing now is the luxury of human engagement," Milton Pedraza, the chief of the

    Luxury Institute, said. Expected spending on experiences such as enjoyable travel and dining is outpacing spending on goods, according to his company's research, and he sees it as a direct response to the rapid increase of screens.

    Screens exposure starts young. And children who spent more than two hours a day looking at screen got lower scores on thinking and language tests, according to early results of a landmark study supported by the National Institutes of Health. The study focuses on brain development of more than 11,000 children. Most disturbingly, the study is finding that the brains of children who spend much time on screens are different. For some kids, their cerebral cortex (大脑皮层) would become thinner before expected time. In adults, one study found an association between screen time and depression.

    There is also the reality that in our culture of increasing separation, in which so many of the traditional gathering places and social structures have disappeared, screens are filling a vital gap.

    For normal people, running away from the screen becomes impossible. It's not a luxury, and it's easy to get. It is normal for more people to need the network constantly. In addition, it has become an important part of social interaction.

There are so many choices when you go shopping. You have to check the sell — by dates so that you know how long you can store and use the food you are purchasing.

But do you know that the best sell — by dates on food packaging don't really tell you if the food is safe to eat. The food may not last as long as it says if it isn't stored correctly at any point of the distribution chain. Now there is food packaging that can detect and change colors if the food has gone bad.

Each American wastes 103 pounds of spoiled food out of the refrigerator every year. The new smart packaging from Primitives Biodesign—a new company that operates out of a lab at Indibio, a biotech accelerator in San Francisco-can help to reduce this huge waste of food.

The basic material that doesn't contain sensing material is made from algae and can block oxygen more effectively than regular film, so the food stays fresher for a longer time. Since it is made from a natural substance, it can also break down in nature.

Making the film smart is the thorny part. Luckily, the team managed to use a process that is like the way nature responds to changes in the environment. The mechanism responds like the way flowers emit compounds to change colors.

"It could be supplement packaging that indicate when it's been tampered with by changing color to tell you that it's no ledger safe," says Kan. She explained that the new packaging can be used on food products to fell if the food has turned bad before someone has to smell or taste it.

The company has proven in lab tests that the technology works and now they are working on how to develop commercial uses for it. The added safety features will come out later. Helping to control food waste in products like meat or cheese which have high greenhouse gas emissions will also help to reduce climate change.

Anyone who has never been to China Braille Library will draw to mind various images of the place.They would wonder how the library works all the way.In fact, the library offers readers a pleasant space with several broad reading rooms on the third floor,and has 18,269 kinds of books, including 3,523 kinds of braille books, 809 kinds of braille journals, 419 kinds of books written in both braille and visible language, and 142 kinds of children's ordinary books.

In the age of multimedia, books have taken various forms. That applies to the world of the visually impaired, too.CBL offers its readers a smart listening device that looks like an old-fashioned cellphone. Guided by a recorded voice, a user has to just press a few buttons to gain access to 20 terabytes of audiobooks stored on the CBL website.The smart listening device is part of a Digital Reading Project for the Blind launched by China Disabled Persons' Federation in 2017.

As part of the program, the government purchased 200,000 such devices and distributed them to the over 400 Braille libraries and barrier-free reading rooms nationwide for lending to the visually impaired. Now, 80 percent of them are still in use, which means more than 160,000 visually impaired people are benefiting from it.
