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.

    Many of us invest valuable time，energy and money planning our vacations. We do this because we know for sure that going on vacations must be good for us. Research proves this feeling without a doubt. Vacations help us perform better at work, improve our sleep quality and cushion us against depression.

    Yet, despite these benefits, many of us return home with a feeling that our last vacation was OK - but not great. In order to change this, some mistakes should be avoided. A classic one for vacation planners is attempting to maximize value for money by planning trips that have too many components (组成部分)• Perhaps you're planning a trip to Europe, seven cities in 10 days，and you realize it will cost only a little more to add two more destinations to the list Sounds fine in theory, but hopping from one place to the next hardly gives an opportunity to experience what psychologists call mindfulness - time to take in our new surroundings, time to be present and absorb our travel experiences. Another mistake is that we worry too much about strategic issues such as how to find a good flight deal，how to get from A to B，or which destinations to add or subtract from our journey. These issues may seem important, but our psychological state of mind is far more important.

    Actually, vacation happiness is based on the following top rules. First, choose your travel companions wisely, because nothing contributes more significantly to a trip than the right companions. Second，don't spend your vacation time in a place where everything is too expensive so as to maintain a positive mood. Third, shop wisely, for meaningful experiences provide more long-term happiness than physical possessions.

    Do you have a spare room in your house? What about your driveway for your car?

    Both of these can help you make money. Many people who have financial difficulties are taking advantage of what's been called the 'sharing economy'.

    Perhaps the best-known example of a company in this field is Airbnb.{#blank#}1{#/blank#}It says it operates in 34,000 cities and it has 800,000 listings of rooms and apartments. They seem to have cornered the market!

    {#blank#}2{#/blank#}Just Park's founder, Anthony Eskinazi, says: "When I had the original idea, I spotted a driveway close to a sports stadium. It would have been so convenient if I could have just parked in that driveway rather than in a commercial car park." And he has a big clientele(客户): Around 200,000 people have advertised their spaces on the site, and he says around half a million drivers use it.  {#blank#}3{#/blank#}They let drivers share their cars with other passengers.

    {#blank#}4{#/blank#}A church near Kings Cross in central London has apparently made over 200,000 pounds by renting out space in its yard to travelers! But the sharing economy has its competitors. People who run things like traditional hotels, commercial car parks and taxi services are afraid of ending up losing money.{#blank#}5{#/blank#}Because this is a new business world, those rules are not there yet. How will renting out your driveway affect your neighbor?

A. Any driver knows how valuable a place to park is.

B. A British company is doing something with parking spaces.

C. There are other sites doing very similar things, like Uber and Lyft.

D. It offers travelers a global network of accommodations offered by locals

E. Another problem is that regulations for these new businesses are unclear.

F. The American web business allows you to rent out your spare room to holidaymakers.

G. Now that the sharing economy is gaining the support of the financial community, corporations start paying attention.

    Thanks to expensive data fees, you might be tempted to log onto that free public Wi-Fi service while you're out and about.{#blank#}1{#/blank#}

    “Think about the cost of being connected all the time. Nothing is free,” David Lee, a product manager for Norton, told CNBC. “{#blank#}2{#/blank#}” The Harvard Business Review agrees: “You're taking a risk every time you log on to a free network in a coffee shop, hotel lobby, or airport lounge.”

    {#blank#}3{#/blank#} According to a survey by the company Symantic, 87 percent of U.S. consumers have used a public internet connection. And it was found that over 70 percent of them checked their personal email through public Wi-Fi, while 11 percent logged onto their online banking account.

    No matter how safe the Wi-Fi connection seems to be, using it leaves your computer or smart phone easy to be attacked by hackers and data thieves. You don't really know who owns and monitors that router, nor who has access to the data that posses through it. Not to mention, hackers have dozens of ways to compromise public Wi-Fi accounts, from creating a network that appears legal to creating pop-ups that trick the user into downloading malware (恶意软件) onto their computers.{#blank#}4{#/blank#}

    To protect yourself against hackers, experts say your best defense is a virtual private network (VPN), which encrypts (加密) your online activity. You can download your very own VPN through an app for Apple or Android devices, or by using the free encryption service CyberGhost{#blank#}5{#/blank#} But before you even start browsing, use this website to make a password that keeps you safe from hackers.

A. These are all of the tricks hackers use to hack your Internet security.

B. That can save you a lot of trouble.

C. The biggest threat is that your data and identity could be completely exposed.

D. Don't let convenience outweigh the consequences, though.

E. Setting up firewalls and antivirus software will also defend your computer against hackers.

F. Unfortunately, most people are unaware of the dangers.

G Hackers usually steal data in this way.

    Changes are hard for many people to accept. However, what's worth keeping in mind is that life is constantly changing. We might lose our jobs, lose our loved ones, or have other life-changing things, but these changes are just part of life. We might not like how society is changing or how our community is changing, but we need to be able to deal with these changes in a positive way. Luckily, there are many ways to view changes, to deal with them and to finally accept them.

To deal with changes wisely, you should accept that feeling when a type of change is upsetting you. There's no way you'll get past it if you ignore it and don't work through it. Thus, if you've lost your job, let yourself feel mad and/or disappointed. You can even express your feelings to others, but do so in a polite way. Also you can ask yourself, "Why am I upset or worried about this change?" Then, "What is it that I believe will happen, as a result of this change?" And then, "Are these thoughts and beliefs correct and practical?" Going through these questions can help you determine if the change is really worth worrying about. What's more, even though the change can have a negative effect on your life, in most situations you can use it to turn a loss into an opportunity or a way to rediscover your enthusiasm for life.

    Of course, when it comes to dealing with changes, taking action is more important. If you're going through a period in your life when the change is negatively influencing you, make yourself busy. Making yourself busy, by working, producing something or engaging socially with others, will do more than just make you forget worries–it'll help you contribute to changing your life positively for the future. Besides, you can try something you've never done before.

    An important part of accepting changes is finding a way to move on and thinking about your future. By looking ahead, you'll be able to better deal with the past and accept it as that had to happen in order to move forward. So accept the change that makes you uncomfortable, and determine you're going to try to use your energies to make an even better world. In this way, you're using it to power what you think is a positive change.

How to save a friendship

    Friends are like stars. Even if you don't see them, you know they are there. And while a shooting star is a beautiful thing to observe, a dying friendship is one of the most painful things to experience. However, if you believe that it is worth trying to save it, then it is worth it. So if you are still moved by a friendship that has given you priceless moments and treasured memories, at least try to save it. While problems are unavoidable, if both of you see the value in saving what you have, focusing on fixing things may just be effective, and your connection may even come through this test stronger than before.

    The moment you realize that the two of you have started growing apart, do something about it. Waiting will only bring about an unavoidable permanency of the loss of your friendship. Be prepared to be the one who makes the first steps; your friend may be laboring under the belief that it is something you have done to harm the friendship, so you shouldn't wait around for them to solve things.

    As life changes around us, friendship change too. However, changes in your life don't mean that your life has to destroy your friendship. Talking openly about the changes is important, as well as accepting that the two of you have changed but still have space, love and respect for one another in your lives. If your friend has distanced himself or herself from you because of changes in your lives, take the chance to show that while life has changed, the importance of your friendship has not.

    Make sure your friend has talked and listened, and both of you have looked for ways to reach compromises（和解）on the things that have weakened your friendship and set the relationship back on track. If you mean as much to this person as they mean to you, you will have at least made some progress in the right direction through mutual（彼此的）compromises in the end.

    Once you have worked through the challenges facing your friendship and come to a shared solution, show your friend how much they mean to you. Start creating new memories and precious moments that will make the unpleasant page in your common history look insignificant and never worth mentioning again.
