    Fairies today are the material of, children's stories, little magical people with wings, often shining with light. Typically pretty and female, like Tinkerbell in Peter Pan, they usually use their magic to do small things and are mostly friendly to humans.

    One explanation suggests the origin of fairies is a memory of real people. So, for example when tribes with metal weapons invaded land where people only used stone weapons some of the people escaped and hid in forests and caves. Further support for this idea is that fairies were thought to be afraid of iron and could not touch it. Living outside of society, the hiding people probably stole food and attacked villages. This might explain why fairies were often described as playing tricks on humans. Hundreds of years ago, people actually believed that fairies stole new babies and replaced them with a "changeling"-a fairy baby-or that they took new mothers and made them feed fairy babies with their milk.

    While most people no longer believe in fairies, only a hundred years ago some people were very willing to think they might exist. In 1917, 16-year-old Elsie Wright took two photos of her cousin, nine-year-old Frances Griffiths, sitting with fairies. Some photography experts thought they were not real, while others weren't sure. But Arthur Conan Doyle, the writer of the Sherlock Holmes detective stories, believed they were real. He published the original pictures, and three more that the girls took for him, in a magazine called The Strand, in 1920. The girls only admitted the photos were not real years later in 1983, and that they created them using pictures of dancers that Elsie copied from a book.

    Ever notice your phone dies faster in cold weather? But why? As LiveScience reports, it all comes down to chemical reactions within the battery.

    If you were to open any smartphone, you'd probably find a Li-ion(锂离子)battery running the show. Inside the battery, there are two poles, a positive pole(正极)and a negative pole(负极), and how much charge your phone has all depends on which side the ions stay. A fully charged battery will be jam-packed with ions on the positive end, while a dead battery will have all the ions stored in the negative end.

    Your phone is powered as the individual ions travel in solution(溶液)from one pole to the other, but a cold temperature doesn't cause the Solution flow in the battery itself. If it flowed, the ions would have to go somewhere, but they actually stay put when it gets cold. The cold temperature causes chemical reactions that slow down the current(电流). The only other time this smaller current is sent through the battery is when all the ions have been spent, so your phone mistakenly reads the slowdown as being out of power.

    Now, how can you get yourself out of this situation? Dr. Stephen J. Harris, a chemist at the Lawrence Berkeley Lab, says whatever you do, don't charge it. Your fully charged battery isn't lacking ions, and the cold temperature isn't allowing more ions to be pulled into the anode. They pass through the solution as solid lithium, which can really do some serious damage to the battery cell itself.

    The only way to get the battery back to life is to let it return to its normal operating temperature. We recommend leaving it in your pocket or spending a few minutes inside away from the bitter cold.

    Is that person really glad to see me? Or is he just being polite? Some people struggle to tell an artificial smile from a truly happy-one. And computers have found this task even more difficult. Recently, researchers have trained a program to detect when a smile is genuine(真诚的).

    Visual computing researchers at the University of Bradford in the U. K. started with a software for analyzing a changing facial expression. This program can examine a video clip of a human head and identify(确认) specific details around the eyes, cheeks and mouth. Then the program tracks the details relative to each other as the face smiles.

    Next, the scientists had their program evaluate(评估)two sets of video clips. In one subjects performed posed smiles. In the other, they watched a film that inspired genuine displays of emotion. The program calculated the differences among the subjects' faces during the two clips. And it turns out that one's mouth, cheeks and eyes move differently when pretending to smile.

    In particular, the muscles around the eyes shift 10 percent more for a real smile than they do for a fake one. These results are in the journal Advanced Engineering Informatics. "A genuine smile is indeed in the eyes. The computer aids analysis of the exact weight distribution of human smiles across the face." Hassan Ugail and Ahmad Al-dahoud say.

    The researchers suggest their work could improve a computer's ability to analyze facial expressions and thus to interact more smoothly with humans. But their real accomplishment is in proving Tyra Banks right: "You have to smile with your eyes."

    Talking to strangers along your travels can change your trip into an adventure. Here are rules of thumb to serve as your guide.

    Don't ignore your fellow tourists. When you go to some place off the beaten path, you're likely to meet other tourists there. Find them, and ask where you would go..

    Abandon your phone. Phones often get between you and the surroundings, ruining your chances to make contact with the people you see., take a deep breath and put it in a different pocket or cover it with tape.

    . The easiest way to do this is to talk to people who are in "open roles", such as anyone in a public service job, or a taxi driver. Or ask someone seated near you; ask where the person's favorite street is; ask if there's a residential area where it would be nice to take a walk.

    Use a map-or none at all. . However, the truth is, sometimes those small streets are nowhere to be found with a map. So ask for directions a lot. Asking for any kind of help is the key to many doors.

    Most Important: Ask good questions. Finding good questions means observing and noticing. A well-turned question shows that you are really paying attentions you are curious and ready to listen..

A. Let strangers make your plans

B. Maps can be of great assistance

C. When the unwillingness gets in the way

D. A good question will get you everywhere

E. They are going to offer advice made of gold

F. Those fellow tourists can make sense of your journey

G. If abandoning your phone isn't practical or feels insecure to you

   Clara was seated on an Airlines flight to LA when a flight attendant asked an urgent question over the loudspeaker, "Does anyone on1know American Sign Language (ASL)?"

   Clara had been studying ASL for the past year and she'd be able to2spell into a man's palm, so she3the call button. The flight attendant came and explained the4, "We have a passenger who's blind and deaf." The passenger seemed to want something, but the flight attendants couldn't5what he needed.

    The Financial Times gave part of my job to a robot named Amy last week. For years I have been making podcast version(播客)of my column, but now I am faced with a tough competition.

    To be fair, Amy (do) something going for her. She has a great voice, smooth as velvet. Her(two) advantage is that she's practically free. She is part of a new service from Amazon that turns text speech, costing-nearly nothing. Even more (impress) is her speed. Less than two seconds after receiving my (write) text, which means when I just start to read, "Yesterday the Finan…", she has already finished.

    Yet once I got over my distress and listened to her work, I felt (good). I know it's early days for her, but at the moment Amy is no match for me. Listening to her is not like listening to non-English speaker read aloud, but to someone without brain, or heart, or sense of humor. Her (deliver) is so poor that I don't even understand. Amy never reads with understanding, never knows when (pause), and never does irony. She continues to get it wrong.

    Finally, I'm not afraid Amy is about to steal my job. Only people possess human touch. It is the heart-to-heart communication makes us special, beautiful and irreplaceable.

    I really wanted to cook when I was four. My dad, however, thinks I was too young to learn cooking. For many years, he only allowed me observe him cook. All I did was watch him in the kitchen. Sometimes, he would not let me give a hand. I really enjoyed stay in the kitchen. Besides, there were also not good kitchen moment. There was a time when the fire became really bigger and I was scared by them greatly. It took about a year of me to overcome my fear of fire. One day, my dad permitted me to start cooking on my own final. You couldn't imagine how happy I was.
