Gardening can be a very relaxing hobby for many people and this wonderful experience is not just for adults. Children are interested in gardening as well, if given the chance to explore nature and science in this way. Gardening can bring joy to both children and their parents alike, especially when the experience is shared together.

    The time that is spent gardening together builds precious memories within their hearts and minds for years to come. When you are gardening with your children, try to give them their own special area. Keep their area in the center of the best soil and light, as you want to make sure of a successful gardening experience.

    Plastic tools easily break and are difficult to use in the dirt, so when you are gardening with your children, give them real tools to use if possible. Even offering to let them use your tools is a way to admit the worth of the work they are doing. It is also important to talk with your children about the whole process of gardening, from planting to the harvest. They need to understand how things work and the importance of what they are doing.

    Show off the children's gardening work by taking friends and visitors for a walking tour through the garden and point out the children's particular spot. When you give attention to the children's work, this is a great motivation（动机） for children to continue wanting to be involved. Do not force children to take part when they are in a bad mood or if they are becoming bored. Instead, allow them to do something different, like building a scarecrow(稻草人)! This makes the gardening experience even more interesting. As you work together side by side with your children, you will encourage a love of the land in them, as well as creating lasting memories of time spent with you.

    Last month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!

    Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth's gravity. It was so hard that we could not say anything to each other. Gradually the weight lessened and I was able to talk to him. "Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground." I asked. "We are too far from the earth now to feel its pull, " he explained, "so we feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth's. " I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.

    When we got there, I wanted to explore immediately. "Come on," I said. "If you are right, my mass will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!" I laughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. "Oh dear," I cried, "walking does need a bit of practice now that gravity has changed." After a while I got the hang of it and we began to enjoy ourselves.

    In 1943, when I was 4, my parents moved from Coeur d'Alene, Idaho, to Fairbanks, Alaska, where adventure was never very far away.

    We arrived in the summer, just in time to enjoy the midnight sun. All that sunlight was fantastic for Mum's vegetable garden. Working in the garden at midnight tended to throw her timing off, so she didn't care much about my bedtime.

    Dad was a Railway Express agent and Mum was his clerk. That left me in a mess. I usually managed to find some trouble to get into. Once I had a little fire going in the dirt basement of a hotel. I had tried to light a barrel(桶) of paint but couldn't really get a good fire going. The smoke got pretty bad, though, and when I made my exit, a crowd and the police were there to greet me. The policemen took my matches and drove me home.

    Mum and Dad were occupied in the garden and Dad told the police to keep me, and they did! I had a tour of the prison before Mum rescued me. I hadn't turned 5 yet.

    As I entered kindergarten, the serious cold began to set in. Would it surprise you to know that I soon left part of my tongue on a metal handrail at school?

    As for Leonhard Seppala, famous as a dog sledder(驾雪橇者), I think I knew him well because I was taken for a ride with his white dog team one Sunday. At the time I didn't realize what a superstar he was, but I do remember the ride well. I was wrapped(包裹) heavily and well sheltered from the freezing and blowing weather.

    In 1950, we moved back to Coeur d'Alene, but we got one more Alaskan adventure when Leonhard invited us eight years later by paying a visit to Idaho to attend a gathering of former neighbors of Alaska.

    WeChat is a social mobile application with voice and text messaging timeline and several social features like ‘Message in a Bottle'. WeChat, a popular instant messaging tool run by Tencent Holdings, aims to help users access mobile services without downloading separate apps, which experts said may challenge the business of smartphone app distributors such Apple Store.

This new feature, named ‘Mini Programs', allows WeChat users to find a variety of services such as ticket buying by scanning a QR (quick-response) code, saving them the trouble of installing a number of different apps on smart devices, according to the transcript of a speech by Zhang Xiaolong, Tencent's senior executive vice president, on Wednesday. The new function is expected to come online on January 9.

    Zhang, known as the father of WeChat, emphasized that ‘Min Programs' is not a mobile app distributing function.

    Still, experts and app developers said that the rollout (推出) of ‘Mini Programs' on WeChat will erode the market share of app distributors like Apple Store in China.

     “‘Mini Programs' will attract lots of start-ups, because a program based on WeChat can help them build up businesses at much lower costs,” a Shanghai-based app developer, told the Global Times Wednesday.

    If a start-up wants to promote its business via a separate application, it has to hire a special team to develop two different apps— one each for iOS and Android.

    Lsiunched in 2011, WeChat has evolved to include services such as ‘Order Taxi', ‘Food Delivery', e-commerce and payments from just an instant messaging app.

    A large body of research has been developed in recent years to explain many aspects of willpower. Most of the researchers exploring self-control do so with an obvious goal in mind: How can willpower be strengthened? If willpower is truly a limited resource, as the research suggests, what can be done to make it stay strong?

    Avoiding temptation (诱惑) is an effective method for maintaining self-control, which is called the "out of sight, out of mind" principle. One recent study, for instance, found office workers less attracted to candy in the desk drawer than that on top of their desks, in plain sight.

    The research suggesting that we possess a limited reservoir of self-control raises a troubling question. When we face too many temptations, are we to fail? Not necessarily. Researchers don't believe that one's willpower is ever completely exhausted. Rather, people appear to hold some willpower in reserve, saved for future demands. The right motivation allows us to tap into those reserves, allowing us to carry on even when our self-control strength has been run down. High motivation might help overcome weakened willpower-at least to a point.

    Willpower may also be made less vulnerable (脆弱) to being exhausted in the first place.

    Researchers who study self-control often describe it as being like a muscle that gets tired with heavy use. But there is another aspect to the muscle comparison, they say. While muscles become exhausted by exercise in the short term, they are strengthened by regular exercise in the long term. Similarly, regular practices of self-control may improve willpower strength.

    The evidence from willpower-exhaustion studies also suggests that making a list of resolutions on New Year's Eve is the worst possible approach. Being exhausted in one area can reduce willpower in other areas, so it makes more sense to focus on a single goal at a time. In other words, don't try to quit smoking, adopt a healthy diet and start a new exercise plan at the same time. Taking goals one by one is a better approach. Once a good habit is in place, Baumeister says, you'll no longer need to draw on your willpower to maintain the behavior. Eventually healthy habits will become routine, and won't require making decisions at all.

Flying High

    Barrington Irving landed his record-breaking light at age 23 and founded an educational nonprofit organization. His message for kids: "The only thing that separates you from scientists is determination, hard work and a strong liking for what you want to achieve." The secret, he believes, is having a dream in the first place.

    The moment of inspiration for Irving came at the age of 15 in his parents' bookstore. One customer, a professional pilot, asked Irving if he'd thought about becoming a pilot. "I told him I didn't think I was smart enough; but the next day he took me to the cockpit (驾驶舱) of the commercial airplane he flew and just like that I was hooked."

    To follow his dream, Irving Turned down a football scholarship to the University of Florida. He washed airplanes to earn money for a flight school and increased his flying skills by practicing at home on a $40 flight simulator (模拟) video game. Then another dream took hold: flying alone around the world. He faced more than 50 rejections for sponsorship before convincing some companies to donate aircraft components. He took off with no weather radar, no de-icing system, and just $30 in his pocket.

    After 97 days, 26 stops and dozens of thunderstorms, he touched down to a cheering crowd in Miami. "It was seeing so many young people watching and listening that pushed me into giving back with my knowledge an experience." Irving has been doing it ever since. He set up his non-profit organization, Experience Aviation (航空), aiming to increase the numbers of youth in aviation career. By bring challenging project-based learning, hands-on and other educational opportunities to school districts and local communities nationwide, the organization has excited the hearts and minds of youth. "We want to create chances for students to accomplish something amazing," he notes. Perhaps Irving's most powerful educational tool is the example his own life provides.
