As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

    "As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

    Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

    In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London-based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so--until this year.

    During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

    Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.

    Kindleysides is training to complete three more marathons next year, including the London Marathon again.

    "Don't answer it," I said to Sam. Our door in the inner city is constantly knocked on; our previous door in the suburbs rarely so. Sam has a full-time job and cannot spend his days answering requests to fix leaking baths or carry cash to the bank.

    Sam opened the door and it was Mervin.

    "There's a bird on the second floor," he said. "It's in trouble."

    Sam followed Mervin upstairs. Mervin pointed and turned to let Sam look. It was a pigeon, the most common of all birds, the bird most likely to foul (弄脏) your newly washed car. And it wasn't flying away. It was stamping in circles. As Sam bent to look, Mervin coughed, "Number two."

    Sam asked him to repeat that. "Number two," Mervin said. "The pigeon has been sitting in his own number two, and now it's stuck to his foot."

It had rained for five days, and the bird was young. It could have been sheltering in a     wet nest of its own waste, which had then dried on its foot, preventing it from flying away. The pigeon moved in a few more circles. Sam bent to take another look. Mervin said, "All right, then." and walked away.

    "Why does everyone think you must solve the problems around here?" I said to Sam when he returned with his story. "It's a bird. Just leave it on the stairs, and let nature take its course." Sam didn't agree. Then he went to the garage and emptied the cardboard box containing our imported camping mats. He returned with the gray pigeon in the box. He showed the bird to our children and they decided to keep it.

    They put its foot in the warm water bath and got rid of its waste. Immediately the pigeon erupted in a bomb of feathers and began flying.

    Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).

    Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.

    However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested. Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.

    The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped. Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.

    What worries some experts more is that screens are becoming part of the middle-class armoury(武器) for perpetuating(巩固) social advantage. Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.

    The skin under the eyes is delicate, which is why it sometimes appears sunken and has darker coloring than elsewhere on the face. Aging and health problems play a role in sunken eyes but other factors can contribute, so it may affect younger people as well.

Dehydration

    The most common cause of sunken eyes is dehydration, or not having enough water in the body. Consuming too much coffee, soda, and prepackaged drinks may increase production of urine(尿液), which may lead to dehydration.

    Vitamin shortages

    Shortages of vitamin C, vitamin K, and iron can cause eyes to become sunken. Vitamin C helps with absorbing iron and decreasing bruising(瘀斑), while vitamin K is responsible for blood thickening, causing unhealthy skin. Easy bruising and unhealthy skin will result in sunken eyes.

    Weight loss

    Most people tend to lose weight in their face first. Sometimes, the weight loss is sudden enough to make blood vessels(血管)below the eyes easy to see, and the skin clear, producing the appearance of sunken eyes. Sudden weight loss may also cause nutritional shortages, which can lead to sunken eyes.

    Not enough sleep or poor quality sleep can cause sunken eyes and a person's DNA or the habit of smoking can also contribute to sunken eyes. Most cases of sunken eyes relate to the quality of an individual's nutrition and healthy living. When these causes are corrected, sunken eyes can be resolved without further treatment. This means that causes can be avoided or treated in good time to prevent the recurrence of sunken eyes.

    Ender's Game

    Aliens(外星人) have attacked Earth twice and almost destroyed the human beings. We couldn't lose anymore. Therefore, the world government has started to train military geniuses(军事天才) in the arts of war. Ender Wiggin is taking part in this training. He wins all the games. He knows time is running out but can he save the planet? It is a good science fiction for boys.

    Hatchet

    It is the story of a boy named Brian. On a trip to the Canadian oilfields to spend the summer with his dad, the pilot of the Cessna he is traveling in suffers a heart attack and dies. Brian must land the plane in the forest. Brian learns to exist in the forest. He faces many dangers including hunger, animal attacks, and even a tornado.

    Ball Don't Lie

    Sticky, 17, is from the streets and has had a tough life so far. But, his hope for his life to be good and get better is basketball. His basketball skills may be his ticket to a better life. This book is inspiring, and raises questions about race and the difficulties in getting ahead in life when you've had a bad start.

    Crackback

    Miles Manning likes to please people, his father, his coach, and his friends. He is a starter on a winning football team that is favored to win the conference and have a chance to go to state. However, everybody is pressing Miles to be bigger, stronger and faster, including his new head coach, his demanding father, and his best friend.

    She

    A college professor and his young student follow instructions on a broken pottery shard (陶瓷碎片) that lead them to a fabled(传说中的) lost city in the jungles of Africa, where they encounter She Who Must Be Obeyed, the ruler of the land.

Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is worth our trust? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given 1, which they can choose to give to Player 2. Any money given to Player 2 is then automatically increased to 2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a part of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling a must to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerted about the effects their actions have on others.
