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.

5 . Physical education, or PE, isn’t required for all high school students. In some schools, it isn’t offered for some different reasons. But should high school students have physical education? The answer is certainly “yes”.

Today many people don’t do sports. But as is known to all. doing sports is very important for an adult. Teaching teens the importance of a healthy lifestyle and making fitness plans now can help teens put exercise in the first place as an adult.

High school isn’t that easy. Many students are under a lot of stress. Stress can be harmful to a student’s studies and life. Doing sports can help them deal with stress better, helping them live a happier life at school.

The American Heart Association says that 10 million kids and teens suffer from obesity (肥胖). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. The increase in activities that don’t get teens to move around, such as computer games, means many teens don’t get their required exercise. PE classes act as a public health measure (措施) to encourage physical activities and help teens have healthy weights.

Not doing sports increases teens’ hazard of developing many diseases. An active lifestyle offers a good way of protection from these health problems. As much as 75 percent of health-care spending goes toward treating medical conditions that can be prevented by lifestyle changes, according to the American College of Sports Medicine.

According to the President’s Council on Fitness, Sports and Nutrition (PCFSN), students who performed five hours of physical activities each week improved their academic (学业的) performance. Students from programs with no physical activity, who used the extra time for classroom study, did not perform better on tests than those who gave up some study time in support of physical education.

10 . It is very obvious that some of the world's top-performing athletes have and feel something deep inside their core that regular athletes simply don't.     1     and are constantly pushing themselves to become better than yesterday. These athletes are the types of people that inspire and motivate other people to really give it their all and if you analyse them you will see that no matter how great they are, they are constantly trying to improve something new that is going to take them to the next level.

First of all, the pursuit (追求) of health and fitness should always start with goal setting.     2    , they have an exact picture of what they are trying to reach and they make sure that their goals are concrete and measurable, so they always have an idea of how far they are from their goals.

These athletes don't limit themselves when it comes to their health accomplishments.     3     even though they really don't know how they are going to reach them at first. They know that by setting high goals their motivation levels will explode and they will be even more fired up to find a way that will make them reach their “impossible” goals. For these guys, nothing is impossible when it comes to health and fitness.

    4     They push themselves as hard as they can and constantly try to reach new levels of success. For the outside world, it might be hard to understand how they can push themselves this hard, but for these super athletes, it is just a game.     5     that they don't even see it as work, they see the whole thing as fun.

A．Last but not least, they are extremely excited and driven by their goals.

B．They always give it their all.

C．Their goals excite and motivate them so much

D．They try their best to shape their bodies

E．Compared to regular athletes who don't set concrete (具体的) goals and monitor them

F．This is what really fuels and drives them when training

G．They set really high goals
