1 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

2 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Up to 82 percent of children with healthy mothers are not easy to be obese（肥胖的）, according to research. A mother,     1     has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke and only     2    (drink) wine in moderation, is significantly less likely     3    (have)a fat child, scientists say.

And research suggests it could be more to do with nurture(养育)    4     nature, as a mother's lifestyle appears     5    (direct) linked to the health of her child. When both mother and child follow a healthy lifestyle, the risk of obesity     6    (reduce)even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged nine     7     fourteen, born to almost 17,000 women in the US. Researchers looked at the link between overall mother health and likelihood of a child     8    (be) obese.

The mother's health was judged on her height-to-weight ratio(比例), her diet, amount of physical     9    (active), smoking status and how much alcohol she drank. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having     10     obese child.

3 . 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.

1. What did scientists from German universities recently discover?

A．Working out is a highly effective way to treat depression.

B．The runner’s high could be caused by endocannabinoids.

C．Endorphins may contribute to one’s high spirits after running.

B．To see the specific symptoms of the runner’s high.

C．To identify what is responsible for the runner’s high.

D．To test what influences the level of endocannabinoids released.

"Pick up the pace!" said Amy's husband. "But I can't!" Amy said, her heart beating quickly inside. "I can't go any faster! Her husband encouraged her. "Yes, you can! You're making progress every day.”

To help Amy stay healthy, her husband had been running with her for over two years. Several years ago, Amy could barely walk down the stairs of her apartment building due to fatness caused by eating disorders. She realized the problem after a failed job interview and began walking to improve her ability to move. At first, she could walk for only 15 minutes at a time. But she pushed herself every day, walking 5 minutes longer than she did the day before until she walked for an hour and eventually two. For three years, Amy kept her walking habit, slowly and painstakingly building her body shape. Then she changed her walking shoes to running shoes about two years ago and became an excellent runner.

In March 2001, an advertisement invited people to nominate（提名）an ordinary person who inspired them to bring the Olympic flame to Salt Lake City as torch bearers（火炬手）or support runners.（Support runners serve as “guardians of the flame" and run with torch bearers along the journey.）Amy's experiences touched her husband, so he nominated her to be a torch bearer. The possibility to be selected was low, but Amy wanted to try.

Running taught Amy the importance of training for a race. She pictured herself running a race and crossing the finish line. For months, she ran through her neighborhood carrying a broken-off broom handle, feeling the weight of the torch. She waved at her neighbors, pretending they were cheering crowds. She also printed a picture of a torch bearer wearing the white uniform, replaced the face with a picture of hers, and put it onto her refrigerator door.

Every day, Amy imagined herself as a torch bearer. She was training for a historic running event. On September 26th, while on her daily run through her neighborhood, an express package arrived.

Olympic and Paralympic medals for the Tokyo 2020 Games will be made from recycled mobile phones donated by the public.

Olympic host cities have     1     (tradition) obtained the metal from mining firms. But Japan,     2     lacks its own mineral resources, is keen on taking the theme of a sustainable future a step     3     (far).

“A project which allows the people of Japan     4     (participate) in creating the medals is really good, and helps raise the environmental awareness of our citizens,” said Tokyo 2020 sports     5     (direct) Koji Murofushi. “    6     the resources of our earth are limited, we need to recycle more and avoid waste. This program is setting an example ”

Collection boxes have been placed in local offices and telecom stores and they will remain there until the metal required     7     (collect).

Members of the organizing committee put forward the idea    8     government officials and companies earlier this year and won their support.

As a result, the medals hanging around Olympic winners’ necks will carry even more meaning than usual. People’s personal memories, once     9     (store) in their smartphones and other handheld devices, will take the round shape of an Olympic medal, one of the most precious     10     (prize) in sport.

6 . Improving as a runner is about more than just running all of the time.    1    In that case, you can make large improvements as a runner in a relatively short time, no matter what your sport, race, or running habits.

    2    It is common for runners to push themselves about the same amount each time, running similarly challenging runs and gradually increasing difficulty. Outstanding runners, however, alternate(交替)an easy, resting run with a very challenging one. It is during these difficult runs，when you really push yourself, that your body snakes the most significant gains.    3    Rather, it is helping rebuild and relax the muscles needed for your big runs.

Keep a relaxed but strong upper body to conserve energy efficiently. You want to keep your chin(下巴)up and your shoulders back, with loose, relaxed arm and hand muscles. Your elbows are bent at 90 degrees but swing freely. If anything, the only muscles you want to focus on keeping strong and tight are the ones in your core(核心).    4    

Use your light run to work up a light sweat. A higher body temperature ensures your muscles are loose and flexible, and your body is pumping blood effectively throughout. For everything other than easy runs, use the first five to ten minutes to build a light sweat and get your body ready for exercise.    5    Slowly pick up speed for short 10 second runs, then return to normal warm-up pace. This helps prepare your muscles for speed.

A．Don't feel like an easy day is "cheating".

B．Alternate easy and hard runs to build strength rapidly.

C．Even five minutes of walking is a good way to get started.

D．"Warming up" truly means you want to warm up your body.

E．You are to pay a little attention to details and a smart training plan.

F．That's because this will naturally help you efficiently channel energy.

G．Remember to relax your face and neck muscles instead of tensing them

7 . A cloudless Southern California sky looms over the Pro Park Course for the Pro Skate Park Series. Here to compete are some of the top female skaters in the world. The women skaters range in age from early adolescence to early 30s, but in a sport that embraces youth, there is one who stands out. At 8 years old, Sky Brown, would be the youngest skater, male or female, ever to compete at this series.

She is known to some — a minor star of the viral age. When her first video was posted to YouTube, Sky initially gained a little internet fame as a premature and level-headed 4-year-old — highly intelligent, well-spoken beyond her years, hugely talented, and yet grounded. Four years later, it was announced that she would be competing at Huntington Beach. Still, the question remains: Is she truly ready, or will this be another case where reality comes crashing down hard on all the hype?

And then, it turns out to be anything but. Sky goes out and presents one surprise after another. Commentators Neal Hendrix and Chris Pastras are left in awe, “Half of the pros can't do.” The only thing that makes the prodigy look like a kid is her size. In every other regard, she holds her own with skaters 10 and 20 years her senior. Before the competition at Huntington, Sky was a curiosity. After, she is a competitor.

Sky's first memory of a skateboard is seeing her father, Stuart, doing a few tricks in front of the family home. “It always looked really fun,” says Sky. “I just kept begging to try it.” Sky progressed quickly, although she never had a formal coach. Somehow she just had the knack. Every movement, every shift in weight, every push and pull of body on board, she absorbed. Then, she did it herself.

“You get so close to making it,” she says of her process, “and think you're about to land it, and then it takes you 100 more times. I'm always saying to my parents, 'Just one last try.'” If anyone was pushing, striving to get better, it was Sky herself, learning new tricks the same way everyone else does — by trying, failing, falling, and getting back up again.
