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.

    We all have our favourite teachers—those who treat us equally. But what about those teachers we don't know as well (for even don't like much)?

You can do lots of things to get a relation with your teacher. First，do the following:{#blank#}1{#/blank#} Complete all homework on time.Be attentive，be respectful，and ask questions.{#blank#}2{#/blank#} Obviously，your teachers are really interested in their subjects or they wouldn't have decided to teach them! Show the teacher that you care，even if you're not good at math or fluent in French—send the message that you are a dedicated student.

    You can also schedule a private meeting during a teacher's free period.{#blank#}3{#/blank#} You can ask questions，inquire about a career in the subject，or talk about your progress in class. You may be surprised to learn that your teacher is a bit more relaxed one on one than when lecturing in front of the whole class.

However，here are some things to avoid when trying to establish a relationship with your teacher：

    ⒈{#blank#}4{#/blank#} Teachers sense when your only motivation is to get special treatment，a college reference，or a job suggestion.

    ⒉Trying to be teachers' pet. You just attract the teachers' attention on purpose and your classmates may start to hate you.

    ⒊{#blank#}5{#/blank#} It's OK to offer a small sign of thanks to teachers if they've been helpful to you. But a teacher is usually not allowed to accept the wrong message，and a teacher is usually not allowed to accept anything expensive.

A．Giving expensive gifts.

B．Show up for class on time.

C．Not being sincere.

D．Find the practical value in classes.

E．Use this time to get extra help.

F．Show an interest in the subject.

G．Get along better with your teachers.

    Do you belong to a highly emotionally intelligent person?

    As we all know, emotional intelligence (EI) has been an important factor in our success and happiness, not only at work, but in our relationships and all areas of our lives. So what sets emotionally intelligent people apart?

    {#blank#}1{#/blank#}

    They focus on the positive. While not ignoring the bad news, emotionally intelligent people do not spend a lot of time and energy focusing on problems. {#blank#}2{#/blank#} These people focus on what they are able to do and what is within their control.

    They surround themselves with positive people. People with a lot of EI don't spend a lot of time listening to complainers. They are aware that those people are not helpful to them. {#blank#}3{#/blank#} You can spot these folks as they tend to smile and laugh a great deal and attract other positive people. Their warmth, openness, and caring attitude let others look upon them as more trustworthy.

    They look for ways to make life more fun, happy, and interesting. Whether it is in their workplace, at home, or with friends, high EI people know what makes them happy and look for opportunities to expand their enjoyment. {#blank#}4{#/blank#} Therefore, they do whatever they can to brighten someone else's day.

    {#blank#}5{#/blank#} People with high EI are so busy thinking of possibilities in the future that they don't spend a lot of time worrying about things that didn't work out in the past. They take the learning from their past failures and apply it to their actions in the future.

A. They are willing to let go of the past.

B. People know how they can use their energy wisely.

C. Here are four habits that people with high EI have:

D. They receive pleasure and satisfaction from seeing others happy.

E. So they always spend time with people that look at the bright side of life.

F. Instead, they use the incident to create awareness of how to not let it happen again.

G. Rather, they look at what is positive in a situation and look for solutions to a problem!

    Humans make mistakes. Even surgeons with years of experience are not infallible. But what if these doctors could pool their knowledge and experience together and create a surgical standard of care, to be carried out by machines?

    That's the idea behind surgical robots, which may soon perform most surgeries, from sewing up tiny wounds to performing heart procedures. Many of these operations are, in fact, already completed with the assistance of robots. But a recent test suggests that robots in the operating room may soon go a step further, performing on soft tissue completely on their own, from start to finish.

    The Smart Tissue Autonomous Robot（STAR）, successfully completed surgeries on pigs. "We're the first group to develop autonomous robotic surgery with soft-tissue surgery, and when compared to standard operation, it's better, "says Peter Kim, professor of surgery. "The idea is not to replace surgeons；it will make the surgeons better and make the procedures safer. "

    A recent Mayo Clinic study found that major surgical errors-including operating on the wrong site or side of the body, or even leaving tools or objects inside the patient-occur every one out of 22, 000 procedures. That's rare, but robots like STAR would aim to lower the number even further.

    In the da Vinci surgical system, surgeons place their arms inside instruments and use their hands to control the movement of robotic tools on the operating table from afar. The robot's every major move is controlled by surgeons, and thus its results may vary based on the surgeon's training or experience.

    STAR, on the other hand, is entirely autonomous. It's not only able to work on its own and perform surgeries with a more flexible "hand", but it's able to react to the unexpected incidents. Cutting into hard tissue like bones is one thing, but operating on moving soft tissue is far more complex. STAR reacts to a changing environment, similar to how self-driving cars are programmed to not only drive on the highway, but also react to another driver making a mistake and getting in your way.

    Is our planet heating up? Are human beings to blame for climate change? {#blank#}1{#/blank#} The discussion on this subject has been heated, but what are scientists actually saying? At Reader's Digest, we decided to find it out.

    {#blank#}2{#/blank#}

    Yes, it has, and even warmer. Greenland was forested between 450,000 and 800,000 years ago, so temperatures were considerably warmer then. There have also been other times of relatively high temperatures.

    So why does the concern exist?

    It's all about the speed at which temperatures are changing. {#blank#}3{#/blank#} But in the 20th and 21^st centuries, especially since 1976, temperatures have probably risen more quickly than during any century in the past 1 ,000 years. Warming may bring improved crop production and other benefits to northern countries such as Canada or Russia. However, many species may not adapt to these conditions, and the one that is able to may cause a problem. {#blank#}4{#/blank#} The West Nile virus, first seen in North America nine years ago, infected about 4,000 people in the US in 2006. The mountain pine beetle, which is active during warmer winters, has already destroyed about 13 million hectares of Canada's forests, worth an estimated $6. 4 billion.

    What is causing the warming?

    IPCC has concluded that human activity is very likely responsible, by increasing the concentrations of greenhouse gases and thus the greenhouse effect. {#blank#}5{#/blank#} They argue the human contribution is nothing.

A. Some scientists, however, still disagree.

B. Has the planet ever been this warm before?

C. Has human behavior made the planet warm?

D. Temperatures have been changing all the time.

E. In the past, temperatures moved up or down gradually.

F. Mosquitoes have been moving northwards to higher places.

G. These questions have burst into newspapers, films and popular books.

    War can be deadly for wildlife, too. A new study reports that war is the biggest threat to Africa's elephants, rhinoceroses, and other animals. Researchers examined how years of conflict in Africa have affected populations of large animals. More than 70 percent of Africa's protected wildlife areas have been within a war zone at some point in the last 70 years. The more frequent the fighting, the greater the drop in animal populations, said Josh Daskin, an ecologist at Yale University. He was the lead author of the study, which was published Wednesday in the journal Nature.

    It takes very little conflict, as much as one conflict in about 20 years, for the average wildlife population to be declining, Daskin said. "Areas with frequent fighting — but not necessarily the bloodiest fighting—lose 35 percent of their large animal populations during each year of war," he said.

Some animals get killed by weapons of war. Yet, many also die because of changes in social and economic conditions in an area as a result of war, said Rob Pringle. He is an ecologist at Princeton University and the study's co-author. "People in and around war zones are poor and hungrier. So they may begin to illegally hunt animals for valuable tusks or hunt protected animals to eat," Pringle said. "And during wartime, animal conservation programs do not have as much money or power to protect wildlife."

    The new study examined the entire African continent over 65 years. The researchers looked at 10 different factors that could change population numbers. They included war, drought, animal size, protected areas and human population density. The number of wars had the biggest effect on wildlife population. The intensity of the wars — measured in the number of human deaths — had the least effect on animals.
