The kids in this village wear dirty clothes. They sleep beside cows and sheep in huts (棚屋) made of sticks and mud. They have no school. Yet they all can sing the English letters, and some can make words.    

    The key to their success: 20 tablet computers (平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

    The goal is to find out whether kids using today's new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project say they're already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten (幼儿园),” said Matt Keller, who runs the Ethiopia program.

The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The tablet's camera couldn't save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn't know any English. That's unbelievable,” said Keller.

The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

    Give yourself a test. Which way is the wind blowing? How many kinds of wildflowers can be seen from your front door? If your awareness is as sharp as it could be, you'll have no trouble answering these questions.

    Most of us observed much more as children than we do as adults. A child's day is filled with fascination, newness and wonder. Curiosity gave us all a natural awareness. But distinctions that were sharp to us as children become unclear; we are numb(麻木的）to new stimulation(刺激), new ideas. Relearning the art of seeing the world around us is quite simple, although it takes practice and requires breaking some bad habits.

    The first step in awakening senses is to stop predicting what we are going to see and feel before it occurs. This blocks awareness. One chilly night when I was hiking in the Rocky Mountains with some students, I mentioned that we were going to cross a mountain stream. The students began complaining about how cold it would be. We reached the stream, and they unwillingly walked ahead. They were almost knee-deep when they realized it was a hot spring. Later they all admitted they'd felt cold water at first.

    Another block to awareness is the obsession(痴迷) many of us have with naming things. I saw bird watchers who spotted a bird, immediately looked it up in field guides, and said, a "ruby-crowned kinglet" and checked it off. They no longer paid attention to the bird and never learned what it was doing.

    The pressures of "time" and "destination" are further blocks to awareness. I encountered many hikers who were headed to a distant camp-ground with just enough time to get there before dark. It seldom occurred to them to wander a bit, to take a moment to see what's around them. I asked them what they'd seen. "Oh, a few birds," they said. They seemed bent on their destinations.

    Nature seems to unfold to people who watch and wait. Next time you take a walk, no matter where it is, take in all the sights, sounds and sensations. Wander in this frame of mind and you will open a new dimension to your life.

    I visited Copenhagen for the first time last Easter. As a student，I'm always strapped for cash，so I assumed I could only afford to breathe the air — but luckily everything about Copenhagen is breathtaking.

I was staying in an Airbnb, and rented a bike so I could cover more ground. One of the first places I visited was the Rundetaarn, or "round tower" built in the 17th century as an astronomical observatory. It has an equestrian staircase (a wide set of stairs big enough for horses to use) that went on and on. As I was going up, I stopped to visit the tower's library hall. At the top, there's a glass platform that gives a view 80-foot straight down, as well as a bell loft. Luckily, the views over Copenhagen from the top were well worth the climb.

    After coming down, I hiked up to the Kastellet Fortress to see the famous Little Mermaid statue. Taking a photo with her was almost impossible with all the tourists crowding around—but sitting there and hearing the lapping waves of the deep blue Baltic Sea, waiting for the sun to set, was an unforgettable and calming experience.

    The next day, I visited the Glyptotek art museum, exploring the grand exhibits. I looked into the marble eyes of many Roman gods，and walked down dimly lit staircases to see mummies from Egypt.

    Before I unwillingly boarded the train back to the airport, I told myself that I must visit again—to experience the thrills of Tivoli Gardens, try more of the street food and everything else from this amazing city.

    Babies teach their older brothers and sisters empathy (移情), according to a new research. Empathy means understanding and entering others' feelings. Until now, younger kids have generally been regarded to learn plenty from their older brothers or sisters but don't give back much. But this study, published in Child Development, confirms that younger siblings (兄弟姐妹) ensure their big brothers and sisters don't grow into disgusting people—no easy task.

    “Although it's assumed that older siblings and parents are the primary socializing influences on younger siblings' development but not vice versa, we found that both younger and older siblings positively contributed to each other's empathy over time,” study co-author Marc Jambon said in a statement. Prior sibling studies have focused on the influence of older brothers and sisters, probably because their impact is most obvious. As one review of literature notes, studies have shown that older siblings influence everything from their younger siblings' motor development to their risk of smoking later in life. And although separated studies have tried to pin down effects that younger siblings have on their older siblings, the influence of baby brothers and sisters remains unclear.

    For this new study, Jambon and his colleagues recruited (招募) a diverse group of 452 Canadian sibling pairs between the ages of 18 months and four years. At the start of the study, individual researchers assessed children's baseline empathy levels by visiting the kids at home and then pretending to hurt themselves or break a valuable item. Eighteen months later, they found small but significant increases in empathy.

    One unexpected exception—older sisters did not appear to experience increased empathy after 18 months living with their little brothers, specifically. The researchers aren't sure why this exception appeared, and they recommend that future studies dive into more complex phenomena.

    At least 12 other murders since 1997 have been linked to an addiction to violent video games. This year, the parents of a 14-year-old murder victim in the UK blamed the killer's addiction to the game Manhunt, causing a government review of legislation (立法) to protect children.

    But is there any scientific evidence that mere games can make children and young adults more aggressive, or possibly have the desire to murder? There is no doubt children are being exposed to more games violence than ever: around a quarter of all games released in the US contain some violence. And the violence is becoming more obvious as increases in computing power make the games look ever more realistic.

    Psychologists think there may be many reasons why violent games are more harmful to children than violent movies. Firstly, players are actively involved in violence, and may begin to use weapons as second nature. Secondly, violent games provide repetitive aggressive experiences that are rewarded by more killing.

    Many studies have shown that people who play violent games regularly are more likely to show high levels of aggression. For instance, in 2000, Craig Anderson of Iowa State University in Ames and his colleague Karen Dill found that people who played violent games were more likely to admit to aggressive behaviour, including attacks or robberies.

    Earlier this year, Krahe and her colleague Ingrid Miller reported a study of 13 to 14-year-old children. More than half had played games recommended only for over-18s. The more violent the games they played, the more they considered physical aggression to be acceptable. Other authors in the same edition report that children who play violent games more likely to argue with teachers and fight with others.

    Experimental studies have also pointed out a possible link. In one, Anderson and Dill asked a group of students to play a violent game, Wolfenstein 3D, while another group played the non-violent Myst. Those who played the violent game were faster to react to aggressive words flashed on screen and appeared more aggressive.

    The issue is controversial, however. Jeffrey Goldstein, a psychologist at the University of Utrecht in the Netherlands and a consultant to some video games publishers, agrees that there is good evidence that children, who are exposed to violent media, including video games, are more aggressive. But he warns it might not be a simple case of cause and effect: aggressive kids might be most attracted to violent games.

    Chinese media and Internet users on Monday decried（谴责）a lack of morals in society after a child was struck twice by two different trucks and left bleeding on the road as more than a dozen bystanders did nothing to help the seriously injured girl.

    The incident, captured by a surveillance camera and aired by Southern Television Guangdong (TVS), showed the two-year-old girl was knocked down and run over by a white truck on a narrow market street on the afternoon of Oct. 13, in Foshan City of Guangdong Province.

    The driver fled the scene of the accident, leaving the girl to bleed on the sidewalk. Over the next six minutes, more than a dozen people walked by the girl, yet not one individual did anything to help her. The girl was then hit a second time by another van before an elderly trash collector came to her aid and brought the attention of the girl's mother, according to the video and eyewitnesses.

    Doctors said that the girl, who was put on life support after being hospitalized, remains in a deep coma. The girl's parents, who are migrants living in the city, are now with her.

    Police said the drivers of both vehicles have been arrested. However, the apathy(冷漠) of the bystanders shown in the video has shocked the public, and people are questioning the morality of society.

    High moral standards were once considered as national pride in China where individuals known for selflessly helping others were adored（崇拜） by the public.

    But in recent years, the perception（观念）of a decline of morals has become a hot topic as profit and materialism are perceived to be affecting society's values.

    On Sept. 2. an 88-year-old man in central China collapsed, his face striking the pavement. Yet, no one came to his aid, and he ended up choking to death on the blood from his nose.

    Some have linked the absence of good Samaritans (模范人物)to a previous case in which a man trying to help an elderly woman who fell was accused of harming her.

    A strong chorus of opinion on the Internet says laws should exempt（免除）Samaritans from liability（责任）, yet laws themselves cannot solve society's morality dilemma.

    Cao Lin, a China Youth Daily commentator, said in a signed article published on Monday that the worry of liability should not be an excuse for not helping, and this case exposes the decline of humanity in Chinese society.
