Youth sport has the potential to accomplish three important objectives in children's development. First, sport programs can provide youth with opportunities to be physically active, which can lead to improved physical health. Second, youth sport programs have long been considered important to youth's psychosocial development, providing opportunities to learn important life skills such as cooperation, discipline, leadership, and self-control. Third, youth sport programs are critical for the learning of motor skills; these motor skills serve as a foundation for future national sport stars and recreational adult sport participants. When coachers develop activities for youth practices and when sport organizations design youth-sport programs, they must consider the implication of deliberate play and deliberate practice.

    Research from Telama （2006） states that regular participation in deliberate play or deliberate practice activities during childhood and youth （ages nine to eighteen） increases the likelihood of participation in sports during adulthood by six times for both males and females. Côté （2002） defines deliberate play activities in sport as those designed to maximize enjoyment. These activities are regulated by flexible rules adapted from standardized sport rules and are set up by the children or by an involved adult. Children typically change rules to find a point where their game is similar to the actual sport but still allows for play at their level. For example, children may change soccer and basketball rules to suit their needs and environment （e.g. in the street. on a playing field or in someone's backyard）. When involved in deliberate play activities, children are less concerned with the outcome of their outcome of their behavior. （whether they win or lose） than with the behavior. （having fun）.

    On the other hand, Ericsson （1993） suggests that the most effective learning occurs through involvement in highly structured activities defined as deliberate practice. Deliberate practice activities require effort, produce no immediate rewards, and are motivated by the goal of improving performance rather than the goal of enjoyment. When individuals are involved in deliberate play, they experiment with different combinations of behaviors, but not necessarily in the most effective way to improve performance. In contrast, when individuals are involved in deliberate practice, they exhibit behavior. focused on improving performance by the most effective means available. For example, the backhand skills in tennis could be learned and improved over time by playing matches or by creating fun practice situations. However, players could more effectively improve their backhand performance by practicing drills that might be considered less enjoyable. Although drills are used in most effective means available practice might not be the most enjoyable, they might be the most relevant to improving performance.

    My name is Clara. I still remember that chilly December day, sitting in science class. I'd finished a worksheet early and picked up a Time for Kids magazine. A piece of news caught my eye. NASA was holding an essay contest to name its Mars rover (火星探测器). Before I even knew anything else about it, a single word flooded my 11-year-old mind: Curiosity.

    I couldn't wait for the bell to ring so I could get started on my essay. That afternoon, I raced home, sat down at the computer, and typed until my fingers ached. “Curiosity is an everlasting flame that burns in everyone's mind…”

Five months later, my mom received a phone call, and immediately, a wide smile spread across her face.

    On August 5, 2012, at 10:31 p.m., the rover named Curiosity touched down safely on the surface of Mars, and I was honored to have a front-row seat in NASA.

    Curiosity is such an important part of who I am. I have always been fascinated by the stars, the planets, the sky and the universe. I remember as a little girl, my grandmother and I would sit together in the backyard for hours. She'd tell me stories and point out the stars. Grandma lived in China, thousands of miles away from my home in Kansas, but the stars kept us together even when we were apart. They were always there, yet there was so much I didn't know about them. That's what I love so much about space.

    People often ask me why we go to faraway places like Mars. My answer is simple because we're curious. We human beings do not just hole up in one place. We are constantly wondering and trying to find out what's over the hill and beyond the horizon.

    More and more corporations are taking an interest in corporate social responsibility (CSR). CSR is made up of three broad layers. The most basic is traditional corporate charity work. Companies typically spend about 1% of pre-tax profits on worthy projects. But many feel that simply writing cheques to charities is no longer enough. In some companies, shareholders want to know that their money is being put to good use, and employees want to be actively involved in good works.

    Money alone is not the answer when companies come under attack for their behavior. Hence the second layer of CSR, which is a branch of risk management. Starting in the 1980s, with environmental disasters such as the explosion at Bhopal and the Exxon Valdez oil spill, industry after industry has suffered blows to its reputation.

    So, companies often responded by trying to manage the risks. They talk to non-governmental organisations (NGOs) and to governments, create codes of conduct（行为准则) and devote themselves to more transparency（透明）in their operations. Increasingly, too. they, along with their competitors, set common rules to spread risks.

    All this is largely defensive, but there are also opportunities for those that get ahead of the game. The emphasis on opportunity is the third layer of CSR: the idea that it can help to create value. If approached in a strategic way, CSR could become part of a company's competitive advantage. That is just the sort of thing chief executives like to hear. The idea of "doing well by doing good" has become popular.

Nevertheless, the business of trying to be good is bringing difficult questions to executives. Can you measure CSR performance? Should you be cooperating with NGOs and you're your competitors? Is there any really competitive advantage to be had from a green strategy?

    Corporate social responsibility is now seen as a mainstream. Big companies want to tell the world about their good citizenship with their devotion to social responsibilities. Done badly, CSR is often just window-dressing and can be positively harmful. Done well, though, it is not some separate activity that companies do on the side, a corner of corporate life reserved for virtue（美德）：it is just good business.

    Walk Out of the Comfort Zone and Try New Things

    For most high school students, free periods are useless. From what I have seen, few do homework, instead many are on their phones and talking, making it impossible for those who actually want to do work to complete any. As a senior next year, I think extra periods should be used to take optional subjects.

Our school offers many classes. Now is the time to experiment in different fields of study. We will never know if we are interested or talented in a subject if we don't try it.

    In my 8th grade, I was told that I had to take an art class as a graduation requirement; so in the 9th grade I took Studio and Art. One of the projects was to build a clay pot, but I built mine incorrectly, so it broke in the kiln (窑). I found out that I have no artistic ability at all, and now I know for sure that I do not want to be an artist. However, the class was one of my favorites that year. I was able to try new activities and test my ability.

    Walk out of our comfort zone and try new things! College is when we should focus on a specific major, but high school is when we have to figure it out.

    Half of all college students change their major at some point. By doing that hundreds of dollars are wasted on classes that they would have never needed to take. So use our extra periods to find out what we want to do in college. The classes we choose can impact us in future. Taking optional subjects will enrich our mind. It will also show colleges we are diverse students.

    When you're sitting at your computer, do you work all day without a break? Or do you allow yourself to become distracted (分心）now and again ... to open a few extra tabs, check social media, read a bit of news, keep up with the latest fashion trends, and maybe catch up on some celebrity gossip.

    Stop! You're 'cyberloafing'. This word is a combination of cyber which means 'related to computers', and 'loafing', which means ' relaxing in a lazy way ' .We do it, and we do it a lot. A study from the University of Texas suggests we are guilty of this form of procrastination (拖延）for 14% of our working day. On a Friday afternoon, I expect it's more than that.

    I'll admit to losing myself in cyberloafing. In fact, I've already done it in the course of writing this story. Okay, more than once. It can damage your productivity and even your career because according to the University of Texas research, each time a worker gets distracted by the Internet, it takes an average of 23 minutes to get back to work.

    More than that, cyberloafing has a dark side, according to a report published in The Journal of Psychosocial Research on Cyberspace. It argues that cyberloafing is connected to several negative personality qualities. People who cyberloaf are more likely to be selfish and tricky.

    Why do we do it? For some, it's most likely an escape from what they're supposed to be doing. Others might get a feeling of satisfaction from finding a great deal online.

    When you have the whole world of the Internet at your fingertips, it's hard to resist.

    How do we solve this problem? If you can truly ask yourself why you are cyberloafing, then that can help identify the base problem. And if that sounds like too much hard work, you could just switch off the Internet for a couple of hours!

    So, in the meantime, let me just close those extra tabs.

    On my first job as a sports editor for the Montpelier Leader Enterprise(MLE), I didn't get a lot of fan mail, so many attention was caught by letter on my desk one morning.

    When I opened it, I read: "Sweet piece of writing on the Tigers. Keep up the good work." It was signed by Don Wolfe, the sports editor. Because I was a teenager, his words couldn't have been more inspiring. I kept it in my drawer until it got old. Whenever I doubted I had the right stuff to be a writer, I would reread Don's note and walk on air again.

    Later, when I got to know him, I learned that Don made a habit of writing a quick, encouraging note to people in all walks of life. "when I made others feel good about themselves," he told me, "I feel good, too."

    Over the years, I've tried to copy Don and write uplifting words, in a world too often cold and unresponsive, such notes bring warmth.

    Why are positive note writers in such short supply? My guess is that people who shy away from the practice are too self-conscious. They are afraid they will be misunderstood. Thus, it may cause troubles and problems. And it sounds insincere on the phone. Also, writing takes time; it is far easier to pick up the phone.

    The drawback of phone calls, of course, is that they do not last. A note attaches more importance to our well-wishing. It is a matter of record, and our words can be read more than once, savored and treasured, and they bring strength and love to us.

    Today I sent a warm letter to my old boss. I don't know if it will make his day, but it made mine. As my friend Don Wolfe said, "Making others feel good about themselves makes me feel good too."
