GLASGOW—the Chinese super star Lin Dan lost a thrilling men's singles final in straight games at the World Badminton Championships here on Sunday.

    The 33-year-old Lin,nicknamed Super Dan by his fans,was 9-13 behind in the first game as the 23-year-old Axelsen,who stands 1.95 meters,took command with powerful attacks.

    Lin,who won his fifth and last world title in 2013,managed to reach 13-13 with well-angled shots.They exchanged the lead several times before Lin took advantage at 20-19.Axelsen,the bronze medalist at last year's Rio Olympics,saved the game point and scored three points in a row for a 22-20 victory.The second game became a one-sided affair when Axelsen led all the way to win 21-16.Lin's expectation of winning a sixth world title was dashed by Denmark's Victor Axelsen.

    Axelsen became the third Dane to take world men's singles title following Peter Rasmussen in 1997 and Flemming Delfs in 1977.“It was a dream for me to win a world title,”Axelsen said.“I was shaking like a little child inside...Lin Dan is an idol for me.”

    Lin suffered his fourth defeat to Axelsen in their seven meetings,but he was satisfied with the result.“I am 34 at the end of this year and 35 next year.I think any player will find it very hard to play a world championships final at this age.I am satisfied with the result.”He added,“We both played well today.I should have killed off the first game when I led 20-19.But I made a mistake at the crucial time.If I won the first game,all the pressure would be at Victor's side.Unfortunately,I have to take all the pressure."

    Lin also dismissed any speculations about his retirement.“I will play in the Chinese National Games which kicks off tomorrow and then the Japan Open.I have been making very good preparations for this competition and I have showed that I am still strong enough physically.”

    In a research carried out in the UK, it was found that only four out of every five employees were happy at work. Surprisingly, it wasn't the pay or the love for the work that made people happy. Instead, friendly, supportive colleagues and a good manager have been found to be the primary causes of happiness at work. So how do you develop a sense of joy on the job? Here are some suggestions.

    Happiness is a state of mind, so staying happy at work is completely based on a positive attitude towards your job. Focus on the bright side of the work rather than keep talking about what makes you unhappy.

    Challenge yourself and take charge of your own growth in your career. Boredom is one of the primary factors that cause people to change jobs. Find new challenges and it's a great feeling to take control over what you do and see a task through.

    Having co­workers you like and enjoy working with is a feature of happiness in the workplace. Talk to people, get to know them and try to get along well with them in the workplace. Meeting new people and getting fresh views can help you to keep yourself interested in your work.

    Complete your tasks, no matter how disagreeable or tough they might be. This gives you a sense of achievement and encourages you to work towards your goals in future.

    Sitting and staring at your screen all day long isn't going to help you. Instead, take breaks and go outside for some time. For example, go out for a few minutes to feel the breeze (微风). Eat your lunch outside or work for a few minutes during that hour, which helps you stay happy at work.

    One evening, author Neil's son was angry. Neil had said one of those things that parents say, like “isn't it time you were in bed.” His son looked up at him, angry and said, “I wish I didn't have a dad! I wish I had … a goldfish!” That conversation gave birth to Neil's book, “The Day I Swapped My Dad for Two Goldfish”. The book is a funny adventure of a son searching for the dad he swapped.

    Whether they realize it or not, fathers play an important role in their children's development. Roland Warren, Director of the National Fatherhood Initiative, says that, “The shape of their dads has a role in the kids' soul.” I agree. We live in the best of times and the worst of times for fatherhood. We live in the best of times because fathers who are engaged in their child's life spend more time than fathers of any previous generation. We live in the worst of times because there are still millions of children who continue to miss the regular presence of Dad.

    What difference does a dad make? Are they really that important? For the most part, studies have proved clearly that fathers, whether they live with their children or not, matter in the lives of their children. When fathers are present, they provide economic support for their children and caregiving responsibilities. Well-fathered children are shown to be more emotionally intelligent and socially successful as adults. When fathers are absent, their absence may negatively influence children's academic achievement, general behavioural adjustment and anger management, especially in males.

    Yet just being physically present isn't enough to be a great father. It is important that a dad be warm and emotionally available to his child. Author and researcher, John Gottman, describes this kind of father as an “emotion coaching father”. Emotion coaches are parents who listen to their children's feelings, see the sharing of feelings as an opportunity for intimacy（亲密）. It is not just the mere presence of fathers that matters, but how they are present. Most children long for and need a loving, devoted and responsible father.

    Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbors, even pets, will all help, but the biggest longevity (长寿) seems to come from marriage. The effect was first noticed in 1858 by William Farr, who wrote that widows and widowers (鳏夫) were at a much higher risk of dying than the married people. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect can be seen in all causes of death, whether illness, accident or self-harm.

    Even if the chances are all against you, marriage can more than compensate you. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Similarly, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are more likely to become ill or die in the couple of years following their husband or wife's death, and caring for your husband or wife with mental disorder can leave you with some of the same severe problems. Even so, the chances favor marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.

    So how does it work? The effects are complicated, affected by socio-economic factors, health-service provision, emotional support and other more physiological mechanisms(生理机制). For example, social contact can promote development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner.

    A life partner, children and good friends are all recommended if you aim to live to 100. The overall social network is still being mapped out, but Christakis says: "People are inter-connected, so their health is inter-connected."

    At times my mom has been uncomfortable seeing these qualities in me. For example, when I was 12, I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico, to always put on sunscreen, not to wander away from my grandmother, and other warnings. She helped me pack and did not leave the airport until she saw my plane take off.

    Despite her worries, she let me go on my own. As I moved into my teens, she continued to give me space to grow and learn, even when it might have been difficult for her. When I reached my senior year, I decided to move away for college. Once again I found that I differed from my peers: while many of them wanted to stay close to home, I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away, she was supportive and excited for me.

    One big thing I realized during my senior year when my mom granted me more freedom was that she actually believed in me and trusted me. That meant a lot. In most time of my life, and especially when I was little, the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best of me. Sometimes it was hard to live up to her standards; getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's.

    I know that her high standards have helped me stay focused on what's important, like education, and made me who I am. I am thankful for her support and involvement in my life. Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

    Scientists recently discovered three tyrannosaur (霸王龙) trackways in Canada. The trackways suggest the meat eaters traveled and hunted in groups. The 70-million-year- old footprints are the first tyrannosaur trackways ever found.

    Tyrannosaurs were a type of meat-eating dinosaur that included the strong Tyrannosaurus rex and Albertosaurus. “Groups of tyrannosaurs may have stuck together as a group to increase their chances of bringing down animals and individually surviving,” study coauthor Richard McCrea says. He works for Canada's Peace Region Paleontology Research Centre. It's believed that tyrannosaurs were solitary creatures. The newly discovered trackways could change the way scientists look at these frightening beasts.

    Trackways can uncover a lot about the social behavior of a species. Unfortunately, very few tyrannosaur footprints have ever been found, and until recently, the only ones known were single prints discovered in Mongolia, the western U.S., and western Canada. But in October 2011, a hunting guide named Aaron Fredlund found two tyrannosaur track marks near Tumbler Ridge, an area in the foothills of the Canadian Rockies. Over the next year, McCrea and his team searched the site and found the remaining trackways.

    The footprints are at about the same depth, which suggests the tyrannosaurs moved through the area at the same time. Impressions of the dinosaurs' rough skin are even visible in the prints. The prints are also in near-perfect condition. That's because the ground had a high clay (黏土 ) content when the dinosaurs walked through the area. The land was later covered by a thick layer of volcanic ash, which kept the marks intact (完整). "This is the most ideal situation you could ask for," McCrea says.

    Researchers aren't sure of the exact species of tyrannosaur that left the prints. But the historic findings show a great deal about how the beasts moved and behaved. “We have extremely convincing evidence that tyrannosaurs traveled in groups,” says McCrea. "This is probably the most important evidence to come out to date on that topic."
