If you see a group of people bend their knees, hold their arms out, and swing their bodies around...don’t panic, just a few surfskaters.

A surfskate board, which originated in the United States, is a type of skateboard that uses a specially-designed front truck to give riders the feeling of surfing on land. As riders shift weight between the heelside and topside, the special front truck turns the board sharply and helps produce momentum(冲力), pushing riders forward and changing directions.

This summer, the sport has gained favor among Chinese consumers and is soaring in popularity among all ages, spurring(刺激) a billion-dollar market.

On lifestyle-sharing platform Xiaohongshu, searches related to surfskating rose 420 percent year-on-year in the first half. The sudden increase in searches started in February. As of August, surfskate-related posts surpassed 60,000. Trending topics include tutorials and board recommendations.

On the short-video platform Douyin, posts labeled “surfskate” had over 150 million views by August. A one-minute video post with top viewership had over 189,000 likes. The sport also became a trendy topic on Weibo and Kuaishou.

“You can see an increasing number of people practicing surfskating at almost all ages in a wide space inside the community I live in.” said Beijing resident Ma Yuan. “I knew about surfskating from social media and decided to give it a try. It was easier than I thought. In addition, surfskating requires a lot less equipment compared with many other sports. I can start skating at a random(任意的) place and all I need is a board. Above all, it helps me lose weight and reduce work and life pressure.”

Boxing has been practiced for centuries— it was even one of the sports in the original Olympic Games in ancient Greece. 【小题1】 Hundreds of thousands of people from all walks of life participate in the sport every week. But why? The answer lies in the physical, mental and even social benefits boxing can bring.

Its physical benefits are clear. Whether it’s practicing with a punching (拳打) bag, training with a partner or facing an opponent in the ring, boxing can be an intense form of exercise and give a full- body workout. 【小题2】 And it can also increase anaerobic (无氧的) fitness— allowing someone to work out harder, for longer. These can, in turn, positively impact other aspects of physical well- being, like heart health and weight management.

【小题3】 Boxing can also positively impact someone’s mental well- being. Dr Jessica Pinchbeck, Senior Lecturer in Sport and Fitness at the Open University, says that boxing can relieve some of the symptoms (症状) of anxiety and depression. Exercising regularly is already widely known to be good for mental health, but boxing can also bring a sense of discipline and focus.

And there is a third benefit to putting on the boxing gloves. Practicing punches can be done alone, of course. 【小题4】 It also involves working with others to train and stay safe. Dr Gavin Williams, Senior Lecturer in Education at the Open University, says that this cooperation and team work can create a sense of identity and belonging. 【小题5】

Physical education, or gym class, 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 (肥胖症). Teens should get 60 minutes of physical activity per day to control their weight and to help their bones get stronger. However, some activities such as video games and computer activities, don’t get teens to move around. The increase in such activities means that many teens don’t get their required exercise. Physical education classes act as a public health measure to encourage activity and help teens have healthy weights.

Inactivity increases teens’ risk 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 hindered 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 activity 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.
