1 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.

But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.

According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.

To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.

“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.

Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.

It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

4 . Benefits of Sports

Doing sports is a physical, mental and social adventure. It’s a great way for children to take a break from studies and release extra energy. It also helps them lead fuller and happier lives as regular sports have proven beneficial to overall well-being.

The physical benefits of doing sports are probably the most obvious. Regardless of your fitness level when you start playing sports, you’ll notice an increase in your overall fitness once you’re involved.     1     Basketball players focus on strength training; football players work on speed while track athletes train through longer runs. The training process helps promote physical fitness and performances in competitions.

    2     Playing sports also contributes to mental health, helping to increase confidence and self-worth. A pat on the back, a high five from a teammate, or a handshake after a match really boosts a child’s confidence. Words of praise and encouragement from the coach, parents and other players raise self-worth.     3     So after a game, it’s a better idea to ask “Did you enjoy the game?” rather than “Did you win?”

Children who participate in sports might also benefit from the social aspect, feeling part of a group, building up responsibility and leadership.     4     Teamwork involves both being dependable as a teammate and learning to rely on your teammates to achieve a positive outcome. Teamwork breeds responsibility and challenges you to be responsible for your actions. Being part of a team gives you an opportunity to be a leader.

Discipline is another social advantage. Most organized sports require a strict training and practice schedule. As a student-athlete, you need to balance studies and athletics.     5    

There is no shortage of reasons to find a sport to get involved in. Are you ready to go? Pick one and get moving!

A．It’s not just your body that benefits from sports.

B．Therefore, playing sports is going to make you more fit.

C．But remember, a child’s self-worth should not be distinguished by victory or loss.

D．If you play group sports, you’ll be part of a team that takes direction from a coach.

E．Nearly every sport requires physical activities and the competitive skills.

F．Among these, learning how to function as part of a team is the most important advantage.

G．Only with strict discipline can you be successful both in the classroom and in the sports field.
