1 . Do you like to keep fit? We’re always told that regular exercise is good for our body and mind. More and more people are taking up activities that improve their fitness. But is there a risk some of us might get addicted and overdo it?

Well, for some people, fitness has become an addiction as they aim for perfection. And fitness trackers and apps can add to it, especially if someone is driven by achievement and perfectionism. And sharing data on social media means exercising becomes public and competitive, which could cause problems in someone who is delicate.

Experts say this can lead to a medical condition called orthorexia nervosa, or addiction to ‘healthy’ eating and over-exercise. Untreated, it can lead to nutritional disorder and mental health confusion. According to a Worklife article:“Research from scientists at University College London in 2017 found that higher social media usage was associated with increased likelihood of developing orthorexia, especially among followers of the ‘healthy eating’ influencers.”

Too much exercise can also take its toll on someone’s physical health as well. Symptoms of over-exercising include injuries such as sprained ankle, tendinitis (腱炎) and a low immune system. So how much exercise is too much? Research by the Journal of the American College of Cardiology found the ideal pace to jog was about eight kilometres per hour—and that it was best to jog no more than three times a week or for 2.5 hours in total, showing that moderate jogging is possibly more beneficial than being inactive or undertaking fierce jogging.

If you’re more of a couch potato, this might sound like good news. But for amateur who can’t help but push their bodies to the limit, the advice from Martin Turner, a sports and exercise psychologist, is, “it’s all about letting go, not being addicted, learning not to control everything, saying, ‘You don’t need to be perfect. ’”

3 . Chinese young gun Yang Qian claimed the first gold of the Tokyo Olympics with a victory in women’s 10m air rifle on July 24 in Tokyo, Japan. Russian markswoman Anastasiia Galashina took the silver and Nina Christen of Switzerland bagged the bronze. Yang, who was ranked sixth in the qualification, scored 251.8 points in the final, beating Galashina’s 251.1 points to set off Team China to a fine start in Tokyo.

Trailing by a mere 0.1 point ahead of the final two shots, Yang saw the gap widen despite a 10.7-point shot, as her rival made an impressive 10.8. However, when it came to the last shot that would define the eventual champion, Galashina surprisingly shot for 8.9 points, and lost the Olympic title to Yang, who had a 9.8.

“I am very happy and proud to win this gold,” said the 21-year-old in a calm tone. The result set the standard for future Olympic competitors as Tokyo 2020 is the first games under new competition rules for the event. “I was extremely nervous before the final shot, and all I could do was to calm down,” the young Olympic champion recalled. “I wasn’t as calm as I appeared to be. During the qualification and the final I kept adjusting my mentality gradually, trying to shake the pressure off me, and I think I did well in doing so.”

Yang had to stand up to a long wait for other shooters to finish their shots before reaching the final. The favored Indian duo, world record holder Apurvi Chandela and world No.1 Elavenil Valarivan, bowed out after the 60-shot qualification round. Norwegian Jeanette Hegg Duestad was the dark horse in the qualification, setting an Olympic record of 632.9 points. But the 22-year-old narrowly missed the medals in the final.

I used to hating swimming and didn't consider learning it. Last year, I couldn't sit and stand because of severe pain caused by the strange illness. My doctor advised me to do some water-based activities. So I begun to learn swimming. Surprising, my pain disappeared when I fully in water. Then, I spent several hour swimming every day. After a swim, I could write at my desk in peace with pain. Swim not only eased my pain, but also gave me the energy I needed it to work. From then on, I never judged anything before I really knew it.

8 . Do you like running enough to make it a habit? Temey Wolfgram does; she has made running a lifelong career and isn’t stopping.

In February, the 16-year-old from Woodbury High School, Minnesota, US, competed at the 2020 US Olympic Trials. She finished the marathon (42,J95 km) with a tune of 2:42:47 as the youngest competitor in the race and ranked 76th out of 390 runners.

Then, in November, Wolfgram, who turned 17, broke the Women's American Junior marathon record with her time of 2:31:49. The old record was 2:34:32, which had stood since 1984. During the run, Wolfgram once hit a wall pretty hard, but she overcame it to finish. ^“I guess I can say I gave it my all,” she told Runner's World. “When I finished, all I was thinking was that I was super happy,” Wolfgram said.

This was only her third marathon. In 2018, when Wolfgram was 15 years old, she ran her first marathon just because she wanted to see if she was capable of doing it. “I believed that I would get faster as the distances got longer... and I'm still glad that I did it.”

When preparing for that first marathon, she ran up to 120 miles （about 190 kilometers） per week. Although her parents didn't have any background in running, they helped Wolfgram train. At first, her dad would take her out in the morning and run about 13 miles. The distance would gradually increase each day. On top of her runs in the morning, she would do cross-country practice after school.

Next, Wolfgram will think about attending the Olympic Games in 2024 after it's scheduled.

9 . The health benefits of staying active are already well-known. It can help you manage weight, keep blood sugar levels down and reduce risk factors for heart disease.

Now, a new study suggests that regularly playing sports, especially badminton or tennis, is not only healthy but also reduces your risk of death, at any age, by approximately 50%. This is a big scale population study to explore the health benefits of sports in terms of death rate. The study evaluated responses from 80, 306 adults aged 30 and above in England and Scotland, who were surveyed about their health, lifestyle and exercise patterns.

After adjusting factors such as age, sex, weight, smoking habits, alcohol use, education and other forms of exercise besides the named sports, the researchers compared the risk of death among people who took part in a sport to those who didn’t. The percentage of reduced risk of death was found to be: 47% for racket（球拍）sports, 28% for swimming and 15% for cycling.

In addition to this, the study didn’t find any significant reduction in the risk for sports like running and football. The findings also exposed that over 44% of the participants met the guidelines for the recommended exercise levels to stay fit and healthy, which amounts to 150 minutes of moderate(适度的) physical activity in a week.

Does this mean you stop running or playing football and switch to tennis instead? Every kind of sport and physical activity has different physical, social and mental benefits attached to it. The apparent lack of benefits of running and football could result from several variables that were not taken into account.

Being active helps you feel happier and live longer. So, the most important step is to take part in any kind of sport that you are likely to enjoy and follow in the long term.

1. How is the study conducted?

A．By doing comparative experiments.	B．By analyzing previous data.
C．By evaluating survey information.	D．By tracking participants for a long time.

2. What does the underlined part “the named sports” refer to?

C．The result of this study is wrong.	D．The study needs to be further improved.

4. What does the author advise people to do?

A．Stick to any sport that you like.	B．Play badminton and tennis only.
C．Stop running and playing football.	D．Do any sport according to guidelines.

10 . 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.
