“I like photography because it captures amazing things that you might not see again,” Timmy Walsh says. He takes pictures of flowers, sunsets and road signs. But those photos don't usually end up in a scrapbook(剪贴簿) or on his bedroom walls.

    When Timmy was five, he found out that his aunt Bev had lung cancer. He wanted to do something to help her. His first idea was to sell his photos from a lemonade--type stand in front of his house in Pennsylvania. “My mom said it wouldn't work because we were not on a busy street,” Timmy explains.

    His next idea was to have an art show. Timmy decorated his home with candles, flowers, and white lights. Then he arranged his photos. Timmy's mom, Sheila, remembers: “Our dining-room table was filled, the living room—everything was filled with photos.” Friends, family, and Timmy's teachers came to the show. He raised more than $300 for cancer research that night. Aunt Bev was “very happy and excited,” he says.

    After a local newspaper wrote a story about Timmy's photos, a volunteer offered to help him set up a website. As people learned about his cause, called Camera for a Cure, Timmy began receiving invitations to sell his pictures at art galleries and fund-raisers. Since then, his work has appeared in more than 20 shows.

    When Timmy is at a show, he greets each customer and talks about what he was thinking when he took his photos. And he always shares facts about lung cancer. Sometimes donations and sales are slow, but that doesn't bother him. “It doesn't matter how much money we made because we just raised awareness,” he says. Timmy knows that finding a cure for lung cancer will take time and effort. So Timmy will keep doing his part by shooting and selling photos of the things he sees.

    This may be music to your ears.

    Researchers P. Jason Rentfrow and Samuel Gosling gave 3,500 people a personality quiz. “We found that the musical styles people like are closely linked to their personalities,” Gosling says.

    RAP/HIP-HOP

    Known for their quick speech, some rappers can say more than 700 syllables（音节）a minute!

    If you like rap/hip-hop, you are energetic（精力充沛的）and have a way with words. You put a fresh spin on things, whether it's new moves on the dance floor or your hip style.

    CLASSICAL

    In the 18th century, classical musicians were like rock stars. Beethoven and Mozart, for example, played in crowded concert halls.

If you like classical, you are open to new ideas and like debating with friends. Creative and imaginative, you can easily spend many hours scrapbooking, writing or painting.

    COUNTRY

    Country music came from the folk songs of English, Scottish, and Irish settlers of the southeastern United States.

    If you like country, you express your opinions well, which makes you the ideal class president or team captain. Traditional and loyal, you enjoy spending time with your family.

    POP

    Pop music is designed to attract almost everyone, and it does. Each year, the industry brings in about 30 billion dollars!

    If you like pop, you are attractive to your friends. You can make big things happen, like planning for a huge party or inspiring your team to victory.

ROCK/ALTERNATIVE

    In the 1950s, rock music created a brand-new culture. Teenagers, for the first time, had an identity separate from adults and children.

    If you like rock/alternative, you are a risk-taker who never accepts no for an answer. You rise to any challenge, like doing very well in a big exam or landing the lead in the school play.

    If these personality profiles（人格剖析）don't match you, that's OK. These are just for fun.

    As Simon Kindleysides, 34, took his first step in the London Marathon in April, he felt as if magic was in the air.

    "As we were walking toward the first mile, we actually started joining all the runners," he said. "Everyone was on the streets, cheering, and that was a magical moment." As time went on, the crowds and other racers spread around. Kindleysides and his team of eight supporters continued walking.

    Kindleysides, who is paralyzed(瘫痪的)from the waist down and typically uses a wheelchair, was equipped with an exoskeleton(体外骨骼)to help him walk. His supporters walked with him to change the batteries in his exoskeleton so he could keep moving.

    In 2013, Kindleysides was diagnosed with a brain tumor (肿瘤) that was growing in a way that pressed on certain nerves, leading to him losing feeling in his legs. He was told he would never walk again. Before his paralysis, the London-based singer and dancer had "always wanted to run a marathon," he said, but he never made the plan to do so--until this year.

    During the London Marathon, the last two miles were the hardest. "At that point, I was exhausted. It was freezing cold, and I was hurting emotionally," Kindleysides said. But he kept going. "I didn't want to let people down. I had a team of eight, and I was raising money for The Brain Tumour Charity," he said. "I didn't want to let them down, myself down, and I thought if I would get this far, I would have to continue."So he continued and made history as the first paralyzed man to complete the London Marathon on foot.

    Then, recovering at home, he shared his accomplishment with his three children. "They used to say I'm the only dad in their whole school who's in a wheelchair, and now they say I'm their dad, the only one who has walked a marathon," he said.

    Kindleysides is training to complete three more marathons next year, including the London Marathon again.

    A European Union program is letting blind people experience famous paintings for the first time. It uses three dimensional (3-D) printing to re-create famous paintings so that they can be touched.

    One painting printed with the new technology is Gustav Klimt's "The Kiss." It is a popular attraction at the Belvedere Museum in Vienna, Austria. The painting shows a man and a woman standing in a field filled with flowers. They are wearing gold robes and have their arms around each other. The man leans down to kiss the woman.

Klimt finished the painting in 1908. Until now, people who have trouble seeing can not enjoy the artwork. But thanks to the reproduction (复制品) they can touch the piece and feel the ridges (隆起) and depressions (凹地). Andreas Reichinger started making 3-D versions of artwork in 2010. He said this reproduction was his most difficult project because the couple's robes are so detailed (精细的).

    Dominika Raditsch is a blind museum visitor. She touched the reproduction. As she moved her hands around it, she said, "Exactly, can you see these? There are so many details." Raditsch said she can imagine what the original painting looks like when she touches the reproduction. "It's somehow round. You can feel it. It comes with it. And in many places it's so smooth. And then I think to myself: it probably shines too!" Raditsch said.

    The Belvedere is not the only museum to have 3-D versions of its artwork. Some of the pieces at the Prado, in Madrid, Spain, have reproductions that can be touched. But the piece in Vienna has one special part: it is made with widely available 3-D printing technology. That means one day, blind art fans anywhere in the world could download the source files and print the reproductions themselves.

    For nearly thirty years I did parent programs in all of the fifty states, and regardless of the community, there was always a shortage of fathers attending, usually by a 10:1 (mothers、 fathers) ratio. Maybe they were all tending to business, and they obviously didn't think school was any of their business.

    The world is now flat. How's that for a sea change? As Thomas Friedman described it in his book The World Is Flat twenty-five years ago, the power structure of the world consisted of highs and lows. The countries with the power and knowledge were at the top of the mountains and the rest were down in the valleys. A handful of countries (the United States, Britain, Germany, and Japan) ruled the world's economy because they monopolize (垄断)the information and power.

    Then came the Internet. Suddenly the countries down in the valleys were connected to the information network and the work flow. These included India, Eastern Europe, South Korea, Brazil, and China. Don't believe it? Walk into a supermarket and pick up any ten toys, checking each for where it was made. My last count: China, ten out of ten. The world's workforce became "flattened". No more disconnected valleys.

    Since 2000, U.S. manufacturing has lost six million jobs, one-third of its workforce, most of them males. For the first time in history, women hold the majority of jobs in the U.S.

    The only people who don't understand the sea change in business are the fathers and sons still clinging to the image of the male who doesn't need to play school—just play ball. It's been thirty years since that idea had any wings, but too many males are still trying to make it fly. Once the only thing that mattered for men was what they could get out of the ground with their hands. Now it's what they can get out of their heads that counts. And without classroom success, today's male faces an impossible challenge from both intelligent women on the home front and foreigners willing to do the same job for less while sitting in an office in Bangalore or Singapore.

    If you're encouraged by the tiny house movement and think 160 square feet is just enough for your needs, you may want to contact the Academy of Construction and Design (ACAD) at IDEA Public Charter School in northeast Washington.

    Students in the program built a micro house with a kitchen, a bathroom, a sleeping loft with space for a queen-size bed and a storage loft, all set on a trailer for mobility. The exterior (外部) of the house was part of a continuous living exhibit in 2015and was moved to the IDEA campus so students could work with builders to complete the interior earlier this year.

    McMahon said the D.C. government's approval to push companies to hire District residents (居民) was at odds with the school system not preparing students for careers in construction, exploring or electrical work. McMahon gathered industry and community leaders to establish ACAD in 2005 and he said 100 percent of the companies he contacted responded positively to the idea, including major firms such as JBG, Clark Construction, Hines Construction and Boston Properties.

    "When students make the connection between what they are learning and a potential career, their academics improve dramatically," said Carol Randolph, chief operating officer of the D.C. Students Construction Trades Foundation. "Some of them who didn't think college was an choice now have a better chance because their classes have become relevant to a job."

    "We teach them life skills and explain that even if you start as a laborer, there are opportunities to move up quickly," he said. "We rewrite the story for them and explain that they can work for a few years, make good money, get promoted, and start their own business or go to school with less debts."

    "Parents and school advisors can be the biggest obstacles because of the negative idea of construction as a blue-collar career," Karriem said. "I get middle-school advisors on board to talk about the opportunities this education provides. These kids are learning lifelong skills that can help them in other fields, provide them with income and allow them to take care of their homes."
