Wearing a red nose for a day may seem like a strange way to raise money for charity. However, it seems to work in Britain

Red Nose Day (RND) is well-known in the UK. The aim of the day is to raise money for a charity called Comic Relief which helps people in need in Africa and in the UK.

    Red nose?

    Comic Relief was started in 1985 by the scriptwriter Richard Curtis. It's called Red Nose Day, as on this day many people buy a plastic red nose to wear! The money made from selling red noses goes to the charity.

    When is RND?

    Red Nose Day takes place every two years in the spring and is now so famous that many people consider it to be an unofficial national holiday. For example, many schools have non-uniform days. This year Red Nose Day was on 13^th March 2015.

    Money

    Across Britain, people are encouraged to “Do Something Funny for Money”. The money that is collected helps children to go to school, and educates the adults with HIV and AIDS. Comic Relief also works closely with disabled and elderly people to make sure they have equal rights and a better life.

    So, if you are ever in the UK on Red Nose Day, now you know why you may find normal people wearing red noses and doing silly things! It's all for a good cause! If you want to find out more about the day, have a look at the official Read Nose Day website.

    Anyone who has ever played the game of Tetris (俄罗斯方块) knows the game's surreal ability to spill into real life. After you shut off the game, you still see those Tetris blocks falling in your mind. You're grocery shopping and find yourself thinking about rearranging items on grocery shelves. Your mind continues to play the game, even when you're physically not.

    Robert Stickgold, a Harvard professor, noticed something similar after a day hiking a mountain. That night, he dreamt he was still going through the motions of mountain hiking. Curious about this, he tried something: he got a group of college students of various skill levels to play Tetris and let them sleep in the Harvard sleep lab.

    Over 60% of the students, including those who suffered from amnesia (健忘症), reported dreams of images of Tetris pieces falling, rotating (旋转), and fitting together. Interestingly, half the Tetris expert students reported such Tetris dreams, while 75% of the beginners did.

    A study found that playing Tetris can grow your brain and make it more efficient. Adolescent girls played the game for an average of 1.5 hours a week over three months. The cerebral cortex (大脑皮层) of the girls grew thicker, while brain activity in other areas decreased. Richard Haier, who had found that there was a "Tetris learning effect", in which the brain consumed less energy as mastery of the game rose, concluded, "The brain is learning which areas not to use."

    Haier's study showed that as the girls practiced playing the game, nerve cells made connections, communicating through synapses (a synapse is a connection between two nerve cells). When you learn something, you change those connections. Every time you reactivate(激活) a circuit, synaptic efficiency increases, and connections become more durable and easier to reactivate. Stickgold says sleep plays a role in this memory process.

    So to sum up, whenever you do specific tasks over and over again, they take up less of your brain power over time. And that's pretty amazing.

    "Dreams may be more important than sleep. We all need to dream," some scientists say. Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer. Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.
    Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memory. Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is hard at work when we dream. That is why we may have a long sleep and still wake up tired.

Dear Alcohol,

    You've been around forever. I can remember all the pain you've caused for me.

    Do you remember the night you almost took my father's life? I do. He loves you. Sometimes I think he loves you more than he loves me. He's addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn't the only one hurt by you that night.

    Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. "I'm so embarrassed," they said as I held their hair back so that they could vomit. "I'm sorry," they said when I called taxies for them, walking them out and paying the driver in advance. "This won't happen again," they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.

    Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn't realize her brother was in the midst of it all. She never saw him again. And it's all your fault.

    I wish you'd walk out of my life forever. I don't want anything to do with you. Look at all the pain you've caused. Sure, you've made people happy too from time to time. But the damage you've caused in the lives of millions is inexcusable. Stop luring (引诱) in the people I love. Stop hurting me, please.

Sincerely,

Me

    In 1988, after being diagnosed with kidney cancer, Fenn, a high-end gallery owner, came up with a crazy plan: He would bury some of his favorite artifacts somewhere in the Rocky Mountains and then die next to them. "My desire was to hide the treasure and let my body stay there and go back to the soil," he explains.

    The contents are worth somewhere between $I million and $5 million. Then he took his treasure chest out into the Rockies and hid it.He wanted it to be found. But he wasn't going to just give it away.

    In 2010, Fenn self-published a book, The Thrill of the Chase, which includes a 24-line poem that Fenn claims contains nine clues that "will lead to my treasure."

    At first, nobody really noticed. But word spread, and the chase was on.(The book is now out of print, and copies show up on Amazon for as much as $3,200.) Fenn estimates that 350,000 people from across the globe have searched or are currently searching for his treasure. Yet nobody has found it.

    The problem with Fenn's poem is that the "clues" can be interpreted a million different ways. The "home of Brown," for instance, could be Browns Canyon National Monument in Colorado, or Brown Hill in New Mexico. Or a cabin or a bear.(Don't laugh; several people have already looked.)

    "It's all in the poem," some have recently started sharing more details," and the treasure isn't in a mine, I mean, they have snakes in' em. It's between 5,000 feet and 10,200 feet above sea level. It's not in Canada or Idaho or Utah or a grave-yard."

    Why are Fenn's treasure hunters so into what seems like a ridiculous thing to do with their time? Many are quick to say that their lives have been enriched by their experiences. "It's changed us," Neitzel says. "made us more confident, and even saved our marriages. Nothing scares us anymore." They thank Fenn for giving them a reason to take a risk, for giving their lives meaning. Many claim that even if they found Fenn's chest, they wouldn't necessarily spend the money—and might even rehide the chest. Another hunter had this tantalizing insight: "I hope that I never find the treasure. The journey will be treasure enough."

    And so the hunt continues.

    In 1972, a social worker named Sanjit Bunker Roy founded Barefoot College in Tilonia, Rajasthan. Today the college trains women from villages for six months to build and maintain solar panels and other instruments. Barefoot College also offers education to the younger generation both during the day and at its solar bridge schools that meet by lamplight at night.

    The philosophy of Barefoot College is largely inspired by the principles of Gandhi, starting with equality beyond caste (种姓), gender or religion. As a matter of fact, women are prioritized (优先考虑) as an underserved population that is essential to bringing villages together. Another central principle of the college is self-reliance, teaching students to support and think for themselves.

    After the college's female students have completed their half-year of training, they return to their villages where they wait for solar panel parts to arrive from the college. Once they have all the pieces they need, they construct the panels and begin collecting solar energy. For each village, the college also provides solar lamps. Villagers can, in addition, order parts for other solar-powered devices, such as water heaters and cooking stoves. Once assembled, they and the lamps are powered by the solar panels.

    The effect on the villages is huge. Before the solar panels and lamps arrived  villagers had only candles to light their homes. This prevented adults from doing serious work at night, and it made studying difficult for children as well. As for physicians, they had difficulty treating patients and performing operations at night because they had to rely on flashlights.

    Now there is power for not only the electrical appliances that the college provides but also devices like televisions, radios and computers. For the first time, the villagers can even connect to the world through the Internet.
