In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

    We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mum's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

    Dad was a Railway Express agent and Mum was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel(桶) of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.

    Mum and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mum rescued me. I hadn't turned 5 yet.

    As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

    As for Leonhard Seppala, famous as a dog sledder(驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped(包裹) heavily and well sheltered from the freezing and blowing weather.

    In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.

    When seeing the doctor, you feel better to know you will get some medicine. But the doctor knows that medicine is not always needed. Sometimes all a sick person needs is some reassurance (安想) that all will be well. In such cases the doctor may prescribe a placebo.

    A placebo is a sugar pill, a harmless shot, or an empty capsule. The patient thinks it is medicine and begins to get better. How does this happen?

    The study of the placebo opens up new knowledge about the way the human body can heal itself. It is as if there was a doctor in each of us. The doctor will heal the body for us if we let it. But it is not yet known just how the placebo works to heal the body. Some people say it works because the human mind fools itself. These people say that if the mind is fooled into thinking it got medicine, then it will act as if it did, and the body will feel better.

    Placebos don't always work. The success of this treatment seems to rest a lot with the relationship between the patient and the doctor. If the patient has lots of trust in the doctor and if the doctor really wants to help the patient, then the placebo is more likely to work. So in a way, the doctor is the most powerful placebo of all.

    A placebo can also have bad effects. If patients expect a bad reaction to medicine, then they'll also show a bad reaction to the placebo. Some doctors still think that if the placebo can have bad effects it should never be used. They think there is still not enough known about it.

    The strange power of the placebo does seem to suggest that the human mind is stronger than we think it is. There are people who say you can heal your body by using your mind. And the interesting thing is that even people who swear this is not possible have been healed by a placebo.

    Helen Monson has always been interested in helping her community. Her first volunteer experience was for the American Red Cross when she was in high school. When she was a school teacher, she also found time to volunteer.

After she retired, she started volunteering to help the old. When her father was older, he was not able to see as well as he used to, which made her sad because he had always enjoyed reading.

    She decided it would be fun to read to elderly people in her community. She also helped one woman write her stories. Ann was almost 100 years old, and Helen wrote down information about her life when she visited Ann. She put the information in a book and got it published. Ann was very excited to share her life story with her children and grandchildren.

    One day Helen read an article in the newspaper about refugees (难民) who needed to learn English. Now, she meets once a week with Sahra, a 38-year-old woman from Somalia. Sahra is learning reading and writing skills. Helen gave Sahra a camera and asked her to take pictures of her daily life. She developed the pictures, and then asked Sahra questions about them. In the end they wrote a book together and used the photos in the book. This helped Sahra learn many new words about her everyday life.

    Helen says, “The most rewarding part of volunteer work is becoming friends with the people I help. They enrich my life as well as I enrich theirs.”

    What are two things that make humans different from animals? One is language, and the other is music. It is true that some animals can sing (and many birds sing. better than a lot of people). However, the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals, have developed musical instruments.

    Music is strange stuff. It is clearly different from language. However, people can use music to communicate things—especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication.

    If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true. Sometimes people who suffer brain damage lose their ability to process language. However, they don't automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer, had a stroke in 1953. It injured the left side of his brain. He could no longer speak or understand speech. He could, however, still compose music until his death ten years later. On the other hand, sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech.

    Why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That's why it may be a way of showing your fitness to be someone's mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition. Finally, when a man sings to the woman he loves, it may be a way of showing off.

    However, Miller's theory still doesn't explain why certain combinations of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research of sounds influence our emotions so deeply. For scientists, this is clearly an area that needs further research.

Libraries

    Public libraries

    Most towns in Britain have a public library. A library usually has a large selection of books and other resources, which library members can use and borrow for free.

    Britain's First Public Library

    The first public library in Britain opened in Manchester in1852. It's first librarian was a man called Edward Edwards, Edwards attended the library's opening ceremony and two famous writers called Charles Dickens and William Thackeray were there too.

    How to Join a Library

    To join a library, go to your local library and fill in a form. You'll receive a library card which is needed when using library services.

    Mobile Libraries

    Not everyone can get a library. Some people live far away from towns and cities. Other people find it difficult to go out because they have an illness or a disability. Thanks to mobile libraries, these people can still borrow books.

    Unlike most libraries, which store books in buildings, mobile libraries usually keep their books in a mini-bus. The back of the mini-bus has shelves for the books, and it is big enough for borrowers to step inside and look around. A driver takes the mini-bus to a certain place at a certain time, so people know when to expect it. They can then return their books and borrow some more.

    All Aboard the Library!

    A school in London didn't have space for a library inside the building. However, everybody agreed that it was still important to have a school library. So the head of the school, Graham Blake decided to park an old bus on the school car park and changed it into a library. Pupils helped to paint the bus, and after eight months, the new library was ready.

    A new "paparazzi-proof" scarf has got heatedly welcomed since launched. A new "paparazzi-proof" scarf could be a game-changer for celebrities who prefer to shy away from the stage light. The ISHU scarf is the creation of Dutch-born fashion entrepreneur Saif Siddiqui and is designed to "give people their right to privacy back". A host of celebrities including Cameron Diaz, singer Joe Jonas, Bayern Munich footballer Jerome Boateng and music producer Major Lazer have worn the ISHU after it was spotted at London Fashion Week last year.

    It works by reflecting the light back into a camera, effectively becoming "invisibility clothes" for celebrities who don't want their photos taken. Anyone wearing the scarf is protected from mobile flash photograph, with the fashion accessory's fabric(附件结构)effectively blocking out any unwanted pictures, although it doesn't stop no-flash photographs from being taken.

    The 28-year-old Siddiqui was inspired while visiting family in Amsterdam in 2009 when his friends attempted to take a photo of him using an iPhone in front of some bikes. "He noticed that the bike's reflector carried the flash of his mobile camera in a way that confused the faces of his friends in the picture." the ISHU website explains. "He immediately realized that if developed into the right product, this feature would be an ideal solution for his friends and is now available to the public who want to keep their private moments in public private. "Saif put together a team of experts who dug into the science of light and reflection, and how to blend technology with fashion."

    He told Decoded Magazine: "The ISHU scarf effectively allows an individual to control what pictures and videos are taken of him." There are no more unwanted pictures and videos on Snapchat, Instagram, or Facebook! Everyone carries a phone with them nowadays that has an amazing camera. So, it all made sense to me." More ISHU products are set to launch in August, with mobile phone cases set to launch in the next few weeks. The ISHU is currently sold out but you can pre-order it online for￡289.
