    Computer programmer David Jones earns $35.000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card. Instead he has been told to wait another two years until he is 18. The 16-year-old works for a small firm in Liverpool where the problem of most young people of his age is finding a job. David's firm releases two new games for the fast growing computer market each month.

    But David's biggest headache is what to do with his money. Even though he earns a lot he cannot drive a car, take out a mortgage（抵押贷款）, or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs”, he said. David spends some of his money on records and clothes and gives his mother 50 pounds a week. But most of his spare time is spent working.

    “Unfortunately, computing was not part of our studies at school”, he said “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.” David added, “I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might disappear.”

    The annual World Economic Forum took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs （企业家）speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

    Richard Liu, founder and chief executive officer of JD

    "Business is not only a way to make money but also a way to contribute yourself, to help people," Liu said in a speech in Davos. "How can we face the fractured (分化的) world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

    Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use ‘cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    The 65-year-old Steve Goodwin was found suffering from early Alzheimer's (阿尔楚海默症). He was losing his memory.

    A software engineer by profession, Steve was a keen lover of the piano, and the only musician in his family. Music was his true passion, though he had never performed outside the family.

    Melissa, his daughter, felt it more than worthwhile to save his music, to which she fell asleep catch night when she was young. She thought about hiring a professional pianist to work with her father.

    Naomi, Melissa's best friend and a talented pianist, got to know about this and showed willingness to help.

    "Why do this?" Steve wondered.

    "Because she cares." Melissa said.

    Steve nodded, tears in eye.

    Naomi drove to the Goodwin home. She told Steve she'd love to hear him play. Steve moved to the piano and sat at the bench, hands trembling as he gently placed his fingers on the keys.

    Naomi put a small recorder near the piano, Starts and stops and mistakes. Long pauses, heart sinking. But Steve pressed on, playing for the first time in his life for a stranger.

    "It was beautiful." Naomi said after listening to the recording. "The music was worth saving."

    Her responsibility, her privilege, would be to rescue it. The music was sill in Steve Goodwin. It was bidden in rooms with doors about to be locked.

    Naomi and Steve met every other week and spent hours together. He'd move his fingers clumsily on the piano, and then she'd take his place. He struggled to explain what he heard in his head. He stood by the piano, eyes closed, listening for the first time to his own work being played by someone else.

    Steve and Naomi spoke in musical code lines, beats, intervals, moving from the root to end a song in a new key. Steve heard it. All of it. He just couldn't play it.

    Working with Naomi did wonders for Steve. It had excited within him the belief he could write one last song. One day, Naomi received an email. Attached was a recording, a recording of loss and love, of the fight. Steve called it "Melancholy Flower".

    Naomi heard multiple stops and starts, Steve struggling, searching while his wife Joni called him "honey" and encouraged him. The task was so hard, and Steve, angry and upset, said he was quitting. Joni praised him, telling her husband this could be his signature piece.

    Naomi managed to figure out 16 of Steve's favorite, and most personal songs. With Naomi's help, the Goodwin family found a sound engineer to record Naomi playing Steve's songs. Joni thought that would be the end. But it wasn't.

    In the months leading up to the 2016 Oregon Repertory Singers Christmas concert, Naomi told the director she had a special one in mind: "Melancholy Flower"

    She told the director about her project with Steve. The director agreed to add it to the playing list. But Naomi would have to ask Steve's permission. He considered it an honor.

    After the concert, Naomi told the family that Steve's music was beautiful and professional. It needed to be shared in public.

    The family rented a former church in downtown Portland and scheduled a concert. By the day of the show, more than 300 people had said they would attend.

    By then, Steve was having a hard time remembering the names of some of his friends. He knew the path his life was now taking. He told his family he was at peace.

    Steve arrived and sat in the front row, surrounded by his family. The house lights faded. Naomi took the stage. Her fingers. His heart.

Western monarch butterflies(帝王蝶)spend their winters on the central California coast. A few months later, they produce young in the Central Valley and as far north and east as Idaho. But where they go in between remains an open question to biologists. Therefore, a group of biologists call on anyone who spots a monarch north of Santa Barbara this spring to get a quick shot(镜头)and email them the photo with a date and a location.

"Something's going on in early spring," said Cheryl Schultz, a professor at Washington State University Vancouver. "Winter survival isn't the problem in the short term, but they don't know whether the monarchs are not making it producing places, not finding plants to feed themselves along the way," she said.

The Western monarch population stood in the millions in the 1980s. In 2017, an annual count found 200,000 butterflies. In 2018, the number fell to about 30, 000-a figure that held steady last year. The monarchs' decline is part of a large trend among dozens of butterfly species in the West. What exactly caused the decline? Biologists attach it to a variety of reasons. Many chemicals are sprayed on the milkweed(乳草)monarchs will feed on. Climate change also plays a role in challenges facing monarchs. Yet, they're not nearly as threatening as those leading to loss of their living room. Farms used to have rough borders that were grounds for the plants monarchs love and live in. However, newly applied practices pushed crops to the edge of fields.

"Butterflies often have good and bad years. We do think there's potential to turn the situation around." Dr. Schultz said. And she said she saw two reasons for that. First, the population decline seen in 2017 ~ 2018 wasn't repeated last year. And second, she's seen butterfly populations recover before.
