Thanksgiving Day is a special holiday in the United States and Canada. Families and friends gather to eat and give thanks for their blessing.

    Thanksgiving Day is really a harvest festival. This is why it is celebrated in late fall, after the crops are in. But one of the first thanksgivings in America had nothing to do with a good harvest. On December 4,1619, the Pilgrims from England landed near what is now Charles City, Virginia. They knelt down and thanked God for their safe journey across the Atlantic.

    The first New England Thanksgiving did celebrate a rich harvest. The Pilgrims landed at what is now Plymouth, Massachusetts, in 1620.They had a difficult time and the first winter was cruel. Many of the Pilgrims died. But the next year, they had a good harvest. So Governor Bradford declared a three­day feast (盛宴).The Pilgrims invited Indian friends to join them for their special feast. Everyone brought food.

    In time, other colonies (殖民地) began to celebrate a day of thanksgiving. But it took years before there was a national Thanksgiving Day. During the Civil War, Sarah Josepha Hale persuaded Abraham Lincoln to do something about it. He proclaimed (宣布) the last Thursday of November 1863 as a day of thanksgiving.

    Today, Americans celebrate this happy harvest festival on the fourth Thursday in November. Canadians celebrate Thanksgiving Day in much the same way as their American neighbours. But the Canadian Thanks­giving Day falls on the second Monday in October.

    Chinese tech giant Tencent Holdings Ltd, the largest global gaming provider and the operator of QQ, an instant messaging software service, has launched a series of scientific exploration events aimed at encouraging young people to explore the outside world, instead of being continuously absorbed online.

    “QQ has been in the market for 18 years, but it is not aging, and its application has become younger and trendier. We hope that more young Chinese can use the app to connect with different people and views worldwide. We never worry about losing game players. Instead, we hope that players can actually go out to learn more,” said Li Dan, general manager of marketing department of the social network group at Tencent.

    China's gaming market netted (净赚) sales revenues of 218.96 billion yuan ( $33.75 billion) in 2017, jumping 23.1 percent year-on-year. Meanwhile, the number of mobile gain players in China reached 462 million, adding 10 percent over the last year. According to Tencent the number of active users of QQ, who are 21 years old or younger, has been increasing, and they tend to use the app for a longer time.

    Starting May 22 of last year, QQ organized free trips for young people to Galapagos, Namibia, Spain and the Antarctic, but it didn't reveal the specific amount it contributed to those trips. During each trip, it selected three to four participants from those who uploaded videos and made specific travel plans online. The finalists stand out with their clear video statements and their enthusiasm about going on adventures.

    “Tencent's approach appears to be contradictory with its own interests. But, in fact, this is consistent with the company's long-term growth strategy and will promote its business by establishing a good social image,” said Neil Wang, president of consulting firm Frost & Sullivan in China.

    Modern festival-goers who worry about ending up with a dead mobile phone battery after days stuck in a muddy field with no electric plug power points may now have a solution—power boots.

    Mobile phone company European Telco Orange has introduced a phone charging prototype(原型)— a set of thermoelectric gumboots or Wellington boots with a “power generating sole” that changes heat from the wearer's feet into electrical power to charge battery-powered hand-helds.

    The boot was designed by Dave Pain, managing director at GotWind, a renewable energy company. Pain said the boot uses the Seebeck effect, in which a circuit made of two dissimilar metals conducts electricity if the two places where they connect are held at different temperatures. “In the sole（鞋底）of the Wellington boot there's a thermocouple and if you apply heat to one side of the thermocouple and cold to the other side it produces an electrical charge,” Pain said. “That electrical charge we then pass through to a battery which you'll find in the heel of the boot for storage of the electrical power for later use to charge your mobile phone.” These thermocouples are connected electrically, forming an array of multiple thermocouples (thermopile). They are then sandwiched between two thin ceramic wafers(薄片). When the heat from the foot is applied on the top side of the ceramic wafer and cold is applied on the opposite side, from the cold of the ground, electricity is made.

    But the prototype boot does have one shortcoming. You have to walk for 12 hours in the boots to make one hour's worth of charge.

    Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, "Mum, I can't peel (去皮)potatoes. I have only one hand. "

    Mum never looked up from sewing. "You get yourself into that kitchen and peel those potatoes," she told me. "And don't ever use that as an excuse for anything again!"

    In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.

    That night I told Mum about it. She hugged me, and I saw her determined look. The next afternoon, she took me back to school. At the deserted playground, Mum looked carefully at the bars.

    "Now, pull up with your right arm," she advised. She stood by as I struggled to lift myself with my right hand until I could get the bar with my other elbow (月寸）.Day after day we practiced, and she praised me for every rung (梯级）I reached.

    I'll never forget the next time, crossing the rungs； I looked down at the kids who were standing with their mouths open.

    One night, after a dance at my new junior high, I lay in bed crying. I could hear Mum came into my room. "Mum," I said, weeping, "None of the boys would dance with me."

    For a long time, I didn't hear anything. Then she said, "Oh, honey, someday you'll be beating those boys off with a bat." Her voice was slight and cracking. I looked out from my covers to see tears running down her cheeks.

    Then I knew how much she suffered on my behalf. She had never let me see her tears.

    Nhon Ly, a 55-year-old Vietnamese-born professional bodybuilder from California has been awarded the "real-life Master Roshi" for his unbelievable similarity to the popular Dragon Ball Z anime(日本动漫) character.

    Ly certainly doesn't look like any other typical 55-year-old man. In fact, he looks a lot better than most guys in their 20s, with his lean(瘦且健康的), strong muscles and youthful attitude. But he's absolutely not the only 50-something man who has the strong muscle in the world.  What really sets Nhon Ly apart from all the rest is his unbelievable similarity to Dragon Ball Z character Master Roshi, also known as the Turtle Hermit, in his "final form". And he apparently liked the comparison so much that he even set his Instagram handle as @master_ roshi_ real_ life.

    According to Madness Media, Ly immigrated to the United States in 1980, at the age of 16. He got a job as a pedicurist(修脚师) at a nail salon, and worked his way up to salon owner. Although he has achieved so much, bodybuilding has always been his biggest love. He has competed in several professional bodybuilding events, with his most notable results being the 4th place at the 2011 US Championship, the 7th place at the 2012 edition, and the 5th place at the 2015 Nationals.

    Even at 55, Nhon Ly continues to train hard in the gym in order to keep his Master Roshi look. He also likes to share photos and videos with his 40,000 fans, many of whom are Dragon Ball Z fans. They routinely post a large quantity of comments, thanking him for training Goku, who is the main character in Dragon Ball media, and asking him to train them in the art of bodybuilding.
