We always knew our daughter Kendall was going to be a performer of some sort. She entertained people in our small town by putting on shows on our front porch when she was only three or four. Blonde-haired, blue-eyed, and beautiful, she sang like a little angel.

    When Kendall was five, we began to notice that she was blinking a lot and clearing her throat frequently. We took her to our local children's hospital where she was diagnosed with Tourette's Syndrome.

    It was pretty devastating（毁灭性的）because other children constantly made fun of her, and sadly, even a teacher teased her. Through all this, Kendall continued to sing and entertain. Remarkably, her tics disappeared when she sang.

    In 2005 when Kendall was sixteen, we thought she was pretty much out of the woods -- or at least heading in that direction. However, a freak accident happened.

    At a birthday party, Kendall hopped on a friend for a piggyback ride. Kendall flew over his back and landed on the cement floor -- on her neck. An ambulance rushed her to the hospital where she spent the next week, paralyzed from the neck down. Ironically, her biggest concern wasn't whether she would walk again, but whether she would be able to audition（试唱）for American Idol.

    Doctors said Kendall had central cord syndrome. Sometimes the pain was so unbearable that she had to bite down on a toothbrush to take her mind off it. As the days dragged on, we didn't know for sure how much of her movement would ever come back.

    I believe Kendall wanted the American Idol audition so much that she willed herself to move again. One of her friends brought a microphone to the hospital and put it on her bed. Every day, Kendall tried hard to pick it up with her right hand. It was more important for her to pick up that microphone than a spoon or fork.

    Sometimes we all cried because of the pain we witnessed. But on the day Kendall walked into the stadium to audition for American Idol – a mere three months after her accident -- we cried tears of joy. And our tears turned into shouts when she was given a golden ticket to Hollywood.

    Kendall is eighteen now, living every day to its fullest. She's recorded a CD with some of John Mellencamp's band members. I'm absolutely sure she's going to make it big some day. Kendall just puts it all in God's hands.

    When she was a little girl trying hard to be strong, she looked up at me, her big eyes brimming with tears, and asked me why she had to have Tourette's Syndrome. My heart ached to make the word right for my child. But I looked right back at her and told her the truth as I see it.

    “Kendall, God gave you a pure heart, an angelic voice, a strong mind, and a beautiful presence. With all of that, he had to make it fair for everyone else.”

    Nelson Mandela is respected and admired around the world. To South Africa he is a superstar. He is a hero who shocked the world by fighting for peace between races, even though he spent 27 years in the prison of the South Africa's white, racist regime(政权).

    Mandela, who won the nation's first all­race elections after the fall of apartheid (种族隔离) in 1994, retired in 1999. But even now, he is as popular as ever.

    His popularity has inspired an entire national industry. His portrait (肖像) has appeared at many places, including on some goods. His face has appeared on a South African coin, a district of a city was named in his honor and some business leaders hope to build a giant statue that looks like him—the Statue of Freedom in celebration of his birthday. It would stand taller than New York's Statue of Liberty.

    His popularity is similar to that of John F. Kennedy in the US or Winston Churchill in Britain, but few politicians today have achieved his level of admiration, said Tom Lodge, head of the Political Science Department of the University of the Witwatersrand.

    "Sometimes it isn't completely appreciated what a skilled performer Mandela has been throughout his political career. He's a very, very clever man."

    However, he is far from perfect.

    Most articles about his birthday, which appeared in every major South African newspaper on the day, briefly mentioned that Mandela did have shortcomings.

    Then they returned to their following praises.

    "Through the ages, the human race has had its icons(偶像)—men and women who rose above ordinary people to inspire their generations," The Mail and Guardian Weekly said, "In our generation, the god brought us Nelson Mandela."

    Forest Schools originated in Sweden in the 1950s and spread to other countries, particularly Denmark where they have become an important part of the Danish early years program.

    In a typical Danish Forest School, young children from 3 years are taken into the forest for 4 hours each day of the week. They take no toys with them, but instead use only what the forest provides (and their imaginations) to develop their games. There is a primitive hut in the forest, which is used in extreme weather. Activities are child-led and fun, such as finding small animals or stomping in puddles. Because of high adult to child ratios, children can safely try out activities which are often considered too dangerous, such as climbing trees or lighting fires, and by dressing the children in good protective clothing, they are able to play freely. By setting children small manageable tasks at which they are unlikely to fail, and giving genuine praise, children's independence and confidence grow.

    A Swedish scientific study found that children in the Forest School are more balanced and socially capable, have fewer sick days, are more able to concentrate and have better co-ordination than the city nursery children. The primary reason appeared to be the greater opportunities to play in nature, so that children play for longer at a time, tending not to disturb each other as much as children in the city nursery. The study observed that where children were interrupted, they became irritable, their stress level rose, and their ability to concentrate fell.

    The study also showed that the Forest School children had 25 % fewer sick days than the city children. One reason for this is that the air is nearly always better outside than indoors. Outside a child is not so exposed to virus and bacteria and not so likely to be infected by other children. Another reason may be that, since stress has been shown to have a negative effect on the immune system, high stress levels may be weakening the city children. The Forest School children, on the other hand, are in a pleasant, natural, fun and less stressful environment.

    Do you often dream at night? How do you feel when you dream? Is it useful to our health? “Dreams may be more important than sleep, and we all need to dream,” some scientists say.

    Dreams take up about one quarter of our sleeping time. People have several dreams each night. Dreams are like short films. They are usually in colour. Some dreams are like old films. They come to us over and over again. That may be because the dreamer is worrying about something. Dreaming may be a way of trying to find an answer. Some people get new ideas about their work from dreams. They may have been thinking about their work all day. These thoughts can carry over into dreams.

    Sometimes we wake up with a good feeling from a dream. But often we can't remember the dream. Dreams can disappear quickly from memory.

    Too much dreaming can be harmful. The more we sleep, the longer we dream. The mind is at work when we dream. That is why we may have a long sleep and still wake up tired.

    Finland is the happiest place on Earth, according to the 2018 World Happiness Report of 156 nations.

    The report, released Wednesday by the United Nations' Sustainable Development Solutions Network, ranks the countries of the world based on six different categories of well-being: income, freedom, trust, life expectancy, generosity and social support. This year's report also pays special attention to the happiness of each country's immigrants.

    The U.S. dropped four spots from 2017 and landed in 18th place, and last year's winner, Norway, came in second place — followed by Denmark, Iceland and Switzerland.

    "The top five countries all have almost equally high values for the six factors found to support happiness, and four of these countries—Denmark, Switzerland, Norway and now Finland — have been in first place in the six World Happiness Report rankings since the first report" in 2012, "co-editor John Helliwell told CNN. "In a division with such excellent teams, changes in the top spot are to be expected."

    Rounding out the top 10 happiest countries was Canada in sixth place, then New Zealand, Sweden and Australia. The order of the top 10 nations changed from the 2017 list but the countries did not, according to the report. They were also 10 of the 11 top spots in the immigrant happiness category (including Mexico — 24th overall, but 10th in immigration).

    "The most striking finding of the report is the remarkable consistency between the happiness of immigrants and the locally born," Helliwell said in a statement. "Although immigrants come from countries with very different levels of happiness, their reported life evaluations resemble those of other residents in their new countries. Those who move to happier countries gain, while those who move to less happy countries lose."

    Other major world powers placed in significantly low spots on the list. Germany came in 15th, the UK was 19th — followed by Japan in 54th place, Russia in 59th and China in 86th.

    The report, based on surveys completed by citizen volunteers, came just under a week before World Happiness Day on March 20, when the UN declared to recognize "the relevance of happiness and well-being as universal goals and aspirations in the lives of human beings around the world and the importance of their recognition in public policy objectives".

    Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.

    Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of "fuel"(燃料).Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) ,like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.

    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality (人的个性). Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.

    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.

    If everybody, were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
