One afternoon last week, I saw three tearful children from my son's school being comforted by teachers. That morning, my 11-year-old had stomach pains, retching(干呕)into a bowl. Talking to other mothers later, I heard about other children with stomachache or difficulty sleeping the night before.

What caused so much pain? Sports day. Sports day might be necessary at a highly-competitive independent school, but not at a village primary school. For the children who can fly like the wind, sports day causes no problem. For those who are overweight or just not good at sport, it is a nightmare(噩梦). Even for those who enjoy running but fall halfway down the track in front of the entire school and their parents, it can prove a disaster.

    Why do we put our children through this annual suffering? Some may say competition is character building; or it's taking part, not winning, that's important; or that it is a tradition of school life. I just felt great pity for those children in tears or in pain.

    Team games at the end of sports day produced some close races, wild enthusiasm, lots of shouting—and were fun to watch. More importantly, the children who were not so fast or quick at passing the ball were hidden a little from everyone's eyes. Some of them also had the thrill of being on the winning side.

    I wish that sports day could be abandoned and replaced with some other less-competitive event. Perhaps an afternoon of team games, with a few races for those who want them, would be less stressful for the children and a lot more fun to watch.

    Green is an important color in nature. It is the color of grass and the leaves on trees. It is also the color of most growing plants.

    Sometimes, the word “green” means young, fresh and growing. For example, a greenhorn is someone who has no experience. In the 15th century, a greenhorn was a young cow or an ox whose horns(角)had not yet developed. A century later, a greenhorn was a soldier who had no experience in war. By the 18th century, a greenhorn had the meaning it has today—a person who is new in a job.

    Someone who is good at growing plants is said to have a green thumb(大拇指). The expression comes from the early 20th century. A person with a green thumb can make plants grow quickly and well.

    Green is also the color used to describe the powerful feeling , jealousy(嫉妒). The green-eyed monster （怪物）is not a dangerous animal from outer space. It is an expression used about 400 years ago by the British writer William Shakespeare in his play “Othello”. It describes the unpleasant feeling when someone has something he wants. For example, a young man may suffer from the green-eyed monster if you get a pay rise and he does not.

    In most places in the world, a green light means to move ahead. In everyday speech, a green light means agree to continue with a project.

    Jim Denevan is an amazing artist whose work is admired by all, but owned by none--that's because all of Jim's art is created on an unusual canvas（画布）--the soft sand. He sometimes spends days working on a piece, only to see it washed away by the sea or a storm and that is just the way he likes it.

    Denevan discovered his artistic talents about ten years ago, when he was wandering aimlessly on the beach with a stick. He ended up drawing a 12-foot-long fish. Since then, Jim has traveled over 1,800 miles while creating over 600 pieces of sand art.

    Over the years, his drawings have become bigger, but the tools he uses haven't changed--All he needs is a stick, a garden rake（耙子）and most importantly, his lively imagination!

    Just like any good artist, Jim is quite particular about the “quality" of his canvas, sometimes walking for miles, looking for perfect sand. His latest piece of work, which is also the world's largest freelance（自由职业的）drawing, was created in the desert sand of Nevada. It took Jim three trips, eight days and over 100 miles of walking to create this 3-mile work of art. It took the storm just one night to destroy it! However, Jim says he actually enjoys watching the waves or rain, wash his paintings away.

    Jim's art has become very popular over the years and was even the topic of a documentary' （记录片）named “Sandman” in 2015. Jim Denevan is not just about art in the sand — he is also an excellent chef （厨师）and founder of an organization called“Outstanding in the Field”，whose motto（座右铭）is to celebrate food at its source. Accordingly, group dining events are held outdoors on farms, with the diners being treated to a delicious meal. The events, which are held in different farms throughout America, are always sold out the minute the schedule is announced.

    The 14-year-old, Amit Dodani, a talented speaker and persuasive debater at school, suffered as a child from a speech disorder.

    He began working with a speech therapist (理疗师) when he was 6 years old, but it was his decision to try out for debate team at the end of seventh grade that helped him most.

    “That experience changed my life,” he wrote after his team went on to nationals. “It gave me hope, and helped me see my own true potential.”

    Since he launched MynameMystory last year, the site has attracted national and even international attention. Amit's mom said her son's website is meant to send a message that no one is alone in their experience, showing how people overcame their challenges and how others can, too.

    “The big thing that clicked in Amit was the belief that people are really needed (to help each other) in this country,” she said. “I wasn't surprised he wanted to do this, because at such a young age he had this spirit in him.”

    In addition to the website, Amit also wanted to expand the idea of sharing stories. So he asked his friends and classmates to donate books to distribute to local hospitals. He hoped to collect perhaps 1,000, but in just two weeks, he received more than 2,300 donations.

    “There was an absolute connection between the website and books,” Amit said. “But books are something that can really make a difference to someone who is in the hospital and can't go to school.”

    Amit said he's hoping to organize a large live event for MynameMystory at the end of this year at Chaminade High School in West Hills. Those who shared their stories on the website will be invited to speak and encourage others to share their stories of overcoming challenges.

    “We're hoping for big things,” Amit said. “We have a lot of events planned out for the future. The goal is basically to inspire people in a different way.”

    You may probably meet most of the powerful graduation speakers, here who are well-known people in their fields. I think the schools couldn't have picked better speakers than them, because they set good examples, deeply inspiring us in our daily life.

    1）Steve Jobs, Stanford University:

   "Remembering you're going to die, and the best way I know is to avoid the trap of thinking that you have something to lose. There is no reason not to follow your heart. Your tine is limited, so don't waste it living someone else's life. Don't let the noise of others' opinions drown out your own inner voice. …"

    2）Oprah Winfrey, Stanford University：

   "I consider the world, this Earth, to be like a school. And the secret I've learned to get ahead is being open to the lessons from the grandest universe of all. Don't react against a bad situation. And the solution will arise from the challenge. So don't give up easily, acting with responsibility. …"

    3）Bono, University of Pennsylvania：

   "For four years you've been buying, trading, and selling everything you've got in his market-place of ideas. Your pockets are full, even if your parent's are empty, and now you've got to figure out what to spend it on…The world is more flexible than you think and it's waiting for you to hammer it into shape…"

    4）Michael Del, University of Texas at Austin;

   "Now it's time for you to move on to what's next and obtain your desire. But you much must not let anything prevent you from taking those first steps. Don't spend so much time trying to choose the perfect opportunity, or sometimes you'll miss the right opportunity. Recognize that there will be failures obstacles. But you will learn from your mistakes and the mistakes of others."

    Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son. Suddenly he seemed to be talking far more to his friends than to his parents. "The door to his room is always shut." Joanna noted.

    Tina and Mark noticed similar changes in their 14-year-old daughter. "She used to sit in my arms on the sofa and talk with me," said Mark. "Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which."

    Before age 11, children like to tell their parents what's on their minds. "In fact, parents are first on the list." said Michael Riera, author of Uncommon Sense for Parents with Teenagers. "This completely changes during the teen years." Riera explained. "They talk to their friends first, then maybe their teachers, and their parents last."

    Parents who know what's going on in their teenagers' lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental (思想的) break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
