It started as a special day for Wesley Autrey, a 50-year-old construction worker in New York City. It was about 12:45 P.M., and he was waiting on a subway platform (月台) to take his daughters home before he went to work. He suddenly noticed a man nearby have convulsions (抽搐) and fall down suddenly. Mr. Autrey and two women went to help the stranger. The man, Cameron Hollopeter, managed to get to his feet, but then stumbled (绊倒) at the edge of the platform and fell onto the subway tracks. Mr. Autrey looked up and saw the lights of the subway train coming near through the tunnel.

    Mr. Autrey jumped onto the track immediately. He realized that he didn't have time to get Mr. Hollopeter and himself back up on the platform before the train arrived, so he lay on top of the man and pressed down as hard as he could. Although the driver tried to stop the train before it reached them, he couldn't. Five cars passed over them before the train finally stopped. The cars had passed only inches from his head.

    New York loves a hero. Mr. Autrey became an overnight hero and was named the “Subway Superman”. New York City Mayor Michael Bloomberg gave him the Bronze Medallion, the city's highest honor. He was asked to appear on several TV talk shows. He was also rewarded with money and gifts, such as $10,000 from Donald Trump, a $5,000 gift card from the Gap clothing store, a new Jeep, and Beyonce concert tickets.

    How did Autrey react (反应) to all this? He said, “I don't feel like I did anything great; I just saw someone who needed help. I did what I felt was right”.

    Look to many of history's cultural symbols, and there you'll find an ancestor of Frosty, the snowman in the movie Frozen. It appeared on some of the first postcards, starred in some of the earliest silent movies, and was the subject of a couple of the earliest photos, dating all the way back to the 1800s. I discovered even more about one of humanity's earliest forms of life art during several years of research around the world.

    For example, snowmen were a phenomenon in the Middle Ages, built with great skill and thought. At a time of limited means of expression, snow was like free art supplies dropped from the sky. It was a popular activity for couples to leisurely walk through town to view the temporary works of chilly art. Some were created by famous artists, including a 19-year-old Michelangelo, who in 1494 was appointed by the ruler of Florence, Italy, to build a snowman in his mansion's courtyard.

    The Miracle of 1511 took place during six freezing works called the Winter of Death. The city of Brussels was covered in snowmen—an impressive scene that told stories on every street corner. Some were political in nature, criticizing the church and government. Some were a reflection of people's imagination. For the people of Brussels, this was a defining moment of defining freedom. At least until spring arrived, by which time they were dealing with damaging floods.

    If you fear the heyday of the snowman has passed, don't worry: I've learned that some explosive snowman history is still being made today. Every year since 1818, the people of Zurich, Switzerland, celebrate the beginning of spring by blowing up a snowman. On the third Monday of April, the holiday Sechselauten is kicked off when a cotton snowman called the Boogg is stuffed with explosive and paraded through town by bakers and other tradesmen who throw bread to the crowds. The parade ends with the Boogg being placed on a 40-foot pile of firewood. After the bells of the Church of St. Peter have rung six times, representing the passing of winter, the pile is lit. When the snowman explodes, winter is considered officially over—the quicker it is burnt down, the longer summer is said to be.

Drinks Have No Wings

    You may have heard that "Red Bull gives you wings". But while most people take the advertising slogan as a metaphor(隐喻), some Americans seem to have taken it very seriously.

    Benjamin Careathers had been drinking the drink for 10 years, expecting to at least feel more energetic, but nothing happened. Feeling fooled by the ad, he took the issue to court.

    In October, the Austria-based company agreed to pay $ 6.5 million (39.7 million yuan) to customers who have bought the drink since 2002. People in the US can apply for a share through energydrinksettlement.com before March 2015.

    But is the case really that ridiculous?

    Red Bull said they had done nothing wrong and they only paid the money to save the cost and trouble of legal action.

    However, the suit(诉讼) told a different story. Even though there is no evidence that Red Bull energy drinks provide more benefit for consumers than a cup of coffee, the company markets their products as a superior source of energy that costs little.

    "Such conduct means that Red Bull's advertising and marketing is not just 'puffery' (吹捧) but is misleading and therefore actionable (可诉讼的) ," the suit said.

    The company said that the drink could promote healthy joints and reduce the risk of eye diseases. However, according to the organization, the product contains a lot of sugar, which could actually lead to many health problems.

    Coca-Cola agreed to pay $ 1.2 million in compensation in July. But to fully stop the company from linking the drink to health benefit, Truth in Advertising, another non-profit organization, took the issue to court again in late October.

    False advertisements have become a common problem around the world. China changed its consumer rights last year to ban advertising companies and media from making or publishing false advertisements. Celebrities are also made responsible if they endorse (代言) false or substandard products.

    There are two type of people in the world. Although they have equal degree of health and wealth and other comforts of life, one becomes happy and the other becomes unhappy. This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds.

    People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather. They enjoy all the cheerful things. Those who are to be unhappy think and speak only of the opposite things. Therefore, they are continually dissatisfied .By their remarks, they sour the pleasure of society, offend many people, and make themselves dissgreeable everywhere .If this turn of mind was founded in nature ,such unhappy persons would be the more to be pitied . The intention of criticizing and being disliked is perhaps taken up by imitation .It grows into a habit, unknown to its possessors. The habit may be strong, but it may be cured when those who have it realise its bad effects on their interests and tastes. I hope this little warning may be of service to them and help them change this habit.

    Although in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck .Those people offend many others; nobody loves them , and no one treats them with more than the most common politeness and respect. This frequently puts them in bad temper and draws them into arguments. If they aim at getting some advantages in social position or fortune, nobody wishes them success .Nor will anyone start a step or speak a word to favor their hopes. If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrong doings. These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others, If they do not, it will be good for others to avoid any contact with them .Otherwise , it can be disagreeable and sometimes very inconvenient , especially when one becomes mixed up in their quarrels.

    The National Storytelling Youth Olympics is an event where thousands of kids from grades 6 to 12 compete against each other by telling stories. It is sponsored by the Master's Degree Program in Reading and Storytelling at East Tennessee State University. The sole purpose of this event is to promote and encourage both the art and science of storytelling among middle school and high school students. Although this event is competitive, its underlying intent and goal is to provide students across the nation with a reason to practice numerous noncompetitive skills.

    Those skills include skillful sportsmanship , responsible behavior, and an attitude of respect for others and the storytelling genre. The eventual goal of the National Storytelling Youth Olympics is to encourage every classroom in America to discover (or rediscover) the beauty of storytelling and story performance.

    The National Storytelling Youth Olympics takes place usually around the first weekend in March. Students from all over the country arrive by bus, plane, or automobile in Johnson City, Tennessee. They usually arrive on Thursday or Friday. Those that arrive on Thursday take advantage of their early arrival by telling stories at local schools. On Friday, an evening meal is prepared for all contestants, coaches, and parents. Games are played, stories are told, and lifetime friendships begin. Saturday is the day of the big event. A luncheon(午餐会) is held in the afternoon so contestants can familiarize themselves with the surroundings and do a sound check.

    The event is divided into three categories separated by grades. Contestants are judged not only by their storytelling performance, but also by the attitude and behavior they display during the entire weekend. A winner is picked from each of the three categories; however, there is an overall winner who is granted the name of Grand Torch Bearer. This person is selected not only by the judges, but also by the contestants. After the winners have been announced, the contestants retreat back to their hotel where a celebratory ice cream party is held; and believe it or not, they tell more stories! This is what the National Storytelling Youth Olympics is all about: developing a love for the art of storytelling.

    Researchers have found bees can do basic mathematics, in a discovery that deepens our understanding of the relationship between brain size and brain power. Recently, A study conducted by researchers from RMIT University in Melbourne, Australia showed that bees could perform arithmetic operations like addition and subtraction (减法).

    Solving math problems requires a complex level of involving the mental management of numbers, long-term rules and short-term working memory. The finding that even the tiny brain of a honeybee can grasp basic mathematical operations has a possible effect on the future development of Artificial Intelligence, particularly in improving rapid learning.

    RMIT's Professor Adrian Dyer said numerical (数字的) operations like addition and subtraction are complex because they require two levels of processing. “You need to be able to hold the rules around adding and subtracting in your long-term memory, while mentally using skillfully a set of given numbers in your short-term memory,” Dyer said. “On top of this, our bees also used their short-term memories to solve arithmetic problems, as they learned to recognize plus or minus as abstract concepts.”

    The findings suggest that advanced numerical cognition (认知) may be found much more widely in nature among non-human animals than previously suspected.

    “If math doesn't require a massive brain, there might also be new ways for us to include interactions of both long-term rules and working memory in designs to improve rapid AI learning of new problems,” said Dyer.

    Many species can understand the difference between quantities and use this to search for food, make decisions and solve problems. But numerical cognition, such as exact number and arithmetic operations, requires a more complex level of processing.

    Previous studies have shown some primates (灵长目动物), birds, babies and even spiders can add and/or subtract. The new research, published in Science Advances, adds bees to that list.
