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 . The annual marathon in my town occurred as scheduled. My job was to follow behind the runners in an ambulance in case any of them needed medical attention. As the athletes began to pace themselves, the front runners started to disappear. It was then that my eyes were drawn to the woman in blue running shorts and a baggy white T-shirt.

I knew we were already watching our “last runner”. Her feet were turned in, yet her left knee was turned out. Her legs were so crippled and bent that it seemed impossible for her to walk, let alone run a marathon.

The driver and I watched in silence as she slowly moved forward. We would move forward a little bit, then stop and wait for her to gain some distance. Then we’d slowly move forward a little bit more. As I watched her struggle to put one foot in front of the other, I found myself breathing for her and urging her forward. I wanted her to stop, and at the same time, I prayed that she wouldn’t.

Finally, she was the only runner left in sight. I sat on the edge of my seat and watched with respect and amazement as she pushed forward with sheer determination through the last miles. When the finish line came into sight, the cheering crowds had long gone home. Yet, standing straight and proud waited a man. He was holding one end of a ribbon tied to a post. She slowly crossed through, leaving both ends of the ribbon fluttering (飘动) behind her.

I don’t know this woman’s name, but that day she became a part of my life — a part I often depend on. For her, it wasn’t about beating the other runners or winning a prize. It was about finishing what she had set out to do. When I think things are too difficult or I get those “I-just-can’t-do-it,” I think of the last runner. Then I realize how easy the task before me really is.

7 . Chloe Kim was one of America's top Olympians during last year's Winter Games in Pyeongchang, South Korea. The snowboarding champion, who grew up in California, competed there at 17 years of age. She became the youngest woman ever to win an Olympic gold medal in the halfpipe competition.

She has recently won a halfpipe competition during the Winter X Games in Aspen, Colorado. But the 18-year-old snowboarder has decided to trade some trips down the halfpipe for an Ivy League education after an upcoming world championship competition in Utah. Beginning from next fall, Kim will be joining Princeton University's class. Instead of centering on the physics of her winning snow board moves, she could now be learning the subject in school. In a recent interview, Kim said, “While I have a special identity and my life has always been so different, I still aim to make my higher education experience as normal as possible.” Kim added, “I'd love to be Chloe, the girl who sits next to me in English class.”

Kim received widespread attention during the Pyeongchang Games. The publicity was fueled by her friendly, energetic nature as well as her interesting family story. Along her path to Olympic gold, Kim also became a social media star. She helped design a snowboarding Barbie doll in her likeness, rapped with hip-hop artist G-Eazy and joined other sports stars to be honored with ESPY Awards. While all of this was fun, Kim says she now looks forward to a new challenge—earning a degree from one of America's top universities. She says she considers her acceptance to Princeton just as much of an honor as earning an Olympic gold medal.

She is still deciding what her exact field of study will be at Princeton. But she says it will involve something science-related, possibly chemistry or biology. She is attempting to work out a plan that will permit her to keep training while going to classes. Kim says her sports and educational goals go hand-in-hand. “It's all about progressing the sport and also pushing myself,” she said. “To see what can do, and how far I can go.”

1. Which of the following statements is TRUE according to the passage?

10 . One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.    1    .

In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.    2     This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least―but still ran. ‘‘Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.

The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do.     3     But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”

    4     Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎症), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.

    5     Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.

A．People may no longer hunt wild animals for their next meal.

B．The physical demands of running affect our body in a beneficial way.

C．Some people run to prevent disease, and others run because it makes them feel better.

D．Runners were 27% less likely to die for any reason, compared with nonrunners.

E．But researchers point out, to infer something like that, they need the whole population measured.

F．But new research suggests people may be able to get life-lengthening benefits by running for far less time.

G．The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying.
