The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid—we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

    However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water's surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ''

    But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn't behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

    Fun though all this may sound, it's still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

     When Regina Spektor moved to the Bronx from Russia as a young child of 9, she could speak no English and her family was so poor that they could afford nothing. Yet she carried with her a love of the piano and music.

     "For me, the thing that I loved the most was playing the piano, so when we left Russia I was so afraid I would forget how to play and I would just find a little table and play my pieces," she told "When you spend your life doing something like playing the piano and then you take that away, it's so surreal."(离奇的)

     Her father, Ilya Spektor, said that, little by little, the family saved enough money to afford their first apartment.

     "I was a photographer and, in six weeks, I found my first job in a big photo lab in Manhattan," he said. On the subway one day, Ilya Spektor spotted a man carrying a violin case. The man also seemed to have an Eastern European accent. A conversation led to a visit and, eventually, Regina Spektor was introduced to Sonia Vargas, a piano teacher. She was a well-known professor who taught piano, took Spektor under her wing and trained her for years, at no cost. "I remember talking to Sonia," Spektor said. "She said that when a student is ready, a teacher appears. So she said that I must have been ready to study piano, and so that's why she came into my life."

     "Immediately, how she played," Vargas said. "You can tell the sound. The sound tell you whether the person loves the instrument, loves the music."

     Much later, while playing her own music and selling a CD that she'd created, Regina Spektor caught the attention of a music producer. The rest is history, complete with concerts around the world and performance in front of the Obamas at the White House.

Regina Spektor greatly appreciated her parents, piano teachers and friends for helping her become the musician she is. “I love the idea that if you're walking toward the world, the world will take some steps towards you,” she said.

    When I was eight, I saw a movie about an island that had an erupting volcano and jungles filled with wild animals. The island was ruled by a beautiful woman called Tondalaya, the Fire Goddess of the Volcano. It was a low-budget(小成本) movie, but to me, it represented the perfect life. But through the years, Tondalaya was forgotten.

    The week I turned 50, my marriage came to a sudden end. My house, furniture and everything I'd owned was sold to pay debts that I didn't even know existed. In a week I had lost my husband, my home and my parents who had refused to accept a divorce (离婚) in the family. I'd lost everything except my four teenage children. I used every penny I had to buy five plane tickets from Missouri to Hawaii. Everyone said I was crazy to think I could just run off to an island and survive. I was afraid they were right.

    I worked 18 hours a day and lost 30 pounds because I lived on one meal a day. One night as I walked alone on the beach, I saw the red orange lava (火山岩) pouring out of Kilauea Volcano in the distance. It was time to live my imagination!

    The next day, I quit my job, bought some art supplies and began doing what I loved. I hadn't painted a picture in 15 years. I wondered if I could still paint. My hands trembled the first time I picked up a brush. But before an hour had passed, I was lost in the colors spreading across the canvas (画布) in front of me. And as soon as I started believing in myself, other people started believing in me, too. The first painting sold for $1,500.

    The past six years have been filled with adventures. My children and I have gone swimming with dolphins, watched whales and hiked around the crater rim (火山口边缘) of the volcano. We wake up every morning with the ocean in front of us and the volcano behind us. The dream I had more than 40 years is now reality. I'm living freely and happily ever after.

    Suppose you are a visitor in the land of Mongolia, some friends ask you to eat with them. What kind of manners do they want you to have? They want you to give a loud burp (饱嗝)after you finish eating. Burping would show that you like your food. In some countries, if you give a big burp, you are told to say “Excuse me, please”.

    In many places people like to eat together. But in some parts of Polynesia it is bad manners（没礼貌） to be seen eating at all. People show their good manners by turning their backs on others while they eat.

    What are manners like in an East African town? The people try not to see you. They are being polite. You may see a friend. He may not see you at all. If you are polite, you will sit down beside him. You will wait until he finishes what he is doing. Then he will talk to you. Manners are different all over the world. But it is good to know that all manners begin in the same way. People need ways to show that they want to be friends.

    FROM dogs and cats to pandas and penguins, lists of adorable animals can be very varied. However, when it comes to scary animals, the answers are often more or less the same­snakes and spiders are among the most dreadful ones for the majority of us.

    However, most of us have never been bitten by a snake or a spider. So does this mean we are born with a fear of certain things?

    Scientists have been actively looking into it for a long time. For example, studies have suggested that babies find live animals much more interesting than stuffed （毛绒填充的） ones. This interest continues even if those animals are snakes and spiders.

    A study published in Psychological Science in 2008seemed to show that snakes did have a different impact on babies. When scientists presented babies with animal videos along with random sounds of happy or frightened human voices, hey found that babies looked at snakes for longer than any other animal however the voices sounded.

    Now, a team from Rutgers University in New Jersey, US has tried to challenge the idea that babies are born with a fear of snakes and spiders. According to the BBC, the researchers measured babies' physiological （生理的） responses as they watched videos of snakes and elephants paired with both fearful and happy voices.

    Scientists then set out to surprise the babies to see how they would react. They presented them with an unexpected bright flash of light as they watched a video. As the BBC explained, a surprise like this would be more intense （强烈的） if the babies were already scared, just like when we watch scary films and jump more if we are already scared.

    However, according to their findings, published recently in the Journal of Experimental Child Psychology, babies 'surprised responses were not bigger when watching a video of a snake, even when it was shown with a fearful voice. Their heart response was also lower, which also made it seem that babies were not scared.

    "Children do not have an innate fear of snakes," concluded the study. Even if previous studies had suggested that babies have different responses to snakes, it isn't necessarily related to fear. "It's possible that paying more attention to something might make fear learning easier later on. It leads to fear learning," said research co­author Vanessa LoBue. She further explained that it was a good thing that humans didn't have an inborn fear of snakes because it would make a young infant's desire to explore new things less strong.

    Instead, we have evolved to quickly learn to be afraid of something if it turns out to be dangerous.
