1 . It is no secret that physical activity is necessary to a person's well-being. Because children are continuously developing physically and emotionally, they are especially affected by the benefits of activity. Former First Lady Michelle Obama's Let's Move initiative reports that nearly one-third of US children are overweight or obese, and that "schools are a key setting for kids to get their 60 minutes of play with moderate activity, given the significant portion of time they spend there."

Physical education programs in schools directly benefit students' physical health. Regular exercise promotes muscles and bone development. In addition to participating in physical activity, students in P.E. learn the fundamentals of a healthful lifestyle, the building blocks upon which they can develop into healthy, knowledgeable adults.

Though the lack of attention on P.E. is often justified as an opportunity to spend more time in the classroom, studies show that physical activity contributes to improved academic performance. Regular activity during the school day is strongly associated with higher concentration levels. A statewide policy in North Carolina requires that children from kindergarten to eighth grade participate in 30 minutes of physical activity each day.

Activities in P. E. help children develop healthful social interactions. From a young age, children learn cooperation through group activities and form a positive sense of identity as part of a team. Such group activities are continually important as children grow older. The International Platform on Sport and Development states that sport has been used as a practical tool to engage young people in their communities through volunteering, resulting in higher levels of leadership and community engagement among young people.

The benefits of P.E. to a child's mental health are both complex and comprehensive. Improved physical health, academics and social interactions all contribute to good mental health. Physical activity sets the stage for a good night's sleep, provides more energy to participate in hobbies and interact with others.

3 . According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?

A study found that gym members were 14 times more active than people who didn’t belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.

The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. “But gym members did more training than non-gym members,” said the lead author, Elizabeth Schroeder of the University of Illinois.

While it might seem clear that gym members exercise more and are healthier than non-gym members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.

You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activity can make you feel happy about life, especially if you run through a forest.

Outdoor exercise is also more interesting than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.

5 . In 2007, Bianca Valenti had an experience which nearly killed her. When she surfed (冲浪) at Ocean Beach in San Francisco, she met a wave as tall as a two-story house.

The wind was strong enough to block my vision. The moment I went under water, I was just getting knocked and spun (旋转) every which way. And then my feet touched the sand bottom there. When I swam to the surface, my lungs were burning painfully. I just thought to myself, “If there’s one more wave after this, I’m going to die.” Luckily there wasn’t another wave. That was when Valenti knew she had the drive and skill to surf big waves.

By 2014, Valenti surfed and won her first big waves contest (比赛) at Nelscott Reef in Oregon. There, she met fellow professionals Alms, Moller, and Kennelly. “One thing got me fired up at that point,” she said. “I wanted to have the opportunity to win more events, but there weren’t more events for women. That’s really annoying.” Luckily, Valenti, Alms, Moller, and Kennelly decided to stick together, support each other, and then fight together.

The four surfers formed Committee for Equity in Women’s Surfing (CEWS) to fight for entrance at Mavericks—a contest set in the surfing location of the same name, north of Half Moon Bay. Mavericks was invitation-only and was open to only men when CEWS was formed. Now, through the organization’s hard work with the State of California, women are allowed to surf in the event.

When Valenti was young, there weren’t many women represented in surfing culture. “I think it’s important for young kids to have all kinds of role models. That way they know all the people who they see as superheroes are just normal people who have crazy dreams. And sometimes the dreams aren’t even that crazy. If you work hard and you stick together with your friends, you can do anything. You can move mountains.”

7 . “Our research has shown that the No. 1 reason people become fans is that it's your connection to your first community,” said Adam Earnhardt, chairman of the communications department at Youngstown State University and co-author of Sports Fans, Identity and Socialization: Exploring the Fandemonium. “I don't care if a Seattle fan moves to China, he or she carries with them their love for the sports teams,” he said. “    1    ”

    2     And when a team begins to catch fire, as with, say, the Mariners in ' 95 or the Seahawks of recent vintage, well, it's easy to get swept up in the wave.

“It's phenomenal,” said Simons. “We have this ability to understand other people so remarkably that their victories literally become ours. Our testosterone literally responds to their victory.     3     They're us, and competing on a literal level as us—a little extension of us.

Professor Robert Cialdini at Arizona State University came up with the term BIRG— Basking In Reflected Glory—to describe the intense pride fans feel when their teams succeed. It can be used as a verb, as in, "Seahawks' fans are currently BIRGing up a storm." The counterpoint, as coined by researchers C. R. Snyder, Mary Anne Lassergard and Carol E. Ford, is the concept of CORFing—Cutting Off Reflected Failure.     4    We've all heard it in action: We won, but they lost.

This leads into another concept, that of cognitive bias, also known as confirmation bias, which causes fans to help explain away defeats by blaming outside factors, such as referees. I'm sure it would also help explain why Seahawks fans rallied around Richard Sherman after his postgame interview, rationalizing behavior that was widely criticized by many fans with no vested interest. It could also explain the notion of "eustress", invented by endocrinologist Hans Selye to refer to a combination of euphoria(极度愉快的心情)and stress, such as that resulting from watching tense sporting events. Indeed, it's much of the appeal.

8 . Yoga (瑜伽) is a kind of sport. It is very popular around the world now. Everyone, young or old, men or women, can do yoga.

There are many reasons why people like yoga. First, yoga can build up your muscle. Your body will become stronger and more flexible. Second, yoga helps you get rid of stress. What's more, yoga can help your mind stay calm. To put it simply, the reason why so many people are falling in love with yoga is that they are discovering how wonderful it is for their mind, body and spirit.

Yoga began in India about 5,000 years ago. At that time, people wanted to be free, healthy and live a long life. As a result, this kind of exercise was born. The early yoga was part of the religion (宗教). It was usually taught one to one—one teacher and one student. Later, it was accepted by more people.

Yoga is an Indian word that means “to join together". There are three parts of yoga altogether: exercise, breathing and meditation (冥想). In the past, people paid more attention to the spirit. The idea behind the exercise was to join the mind, body and spirit as one.

With the development of the exercise, more and more people are doing yoga as a way of keeping healthy. Among them, office ladies enjoy doing yoga most. Yoga can give them peace, help them feel relaxed and have fewer worries and illnesses.

How glad I’m to hear from you!

10 . Here is one of the world’s largest indoor ski-slopes. It covers an area of 22,500m², about the same size as three football fields, and the temperature is a constant -1℃ to -2℃. However, the strangest thing about this place is that it’s in the middle of the desert! It’s called Ski Dubai and the outside temperatures can rise to more than 40℃!

It sounds crazy, but it just shows how serious people are about having fun. We spend huge sums on sports facilities. We pay our sports stars ridiculous amounts of money. And we spend hour after hour playing games! I wonder if all the sports-lovers and game-players in the world aren’t a little crazy. I know I am. I was once driving past a football field where some kids were playing. I turned to watch and crashed my car. I know it’s stupid but I can do nothing about it. As someone said, “Football isn’t a matter of life and death. It’s much more important than that!”

Of course, it isn’t that important really. No game is. But the problem is that games are addictive (使人上瘾的). From the tennis court to the golf course, you’ll find participants and spectators who can’t live without the drug of their choice. It could be a good thing. After all, despite being addictive, it’s true that sports and games help us to relax. Maybe if it wasn’t for sport, our societies would be more violent. Perhaps sport is a substitute for war? It’s hard to think of a quieter, more peaceful game than chess, and what’s the objective? Capturing your opponent’s king. And surely, it’s better to have wars in athletics stadiums rather than on battlefields.

What’s more, playing is natural. Kittens chase balls of wool and puppies pretend to fight. Games help us perfect our skills and prepare us for the serious contest of survival.

But do all games help us relax and stay away from violence? What about computer games? A recent article in New Scientist suggests that playing violent video games (and most of them are extremely violent) makes people more aggressive and more likely to commit violent crimes.

Are these games a rehearsal (彩排) for life or a substitute for life? Do we play instead of facing up to our real problems? I don’t know. But what I do know is that I need a break. Something to help me relax. Skiing would be nice. I wonder how much it costs to get to Dubai?
