“There is a long , long story     1     Tai Chi and me.” says jose Gago, 61, a Spanish man who has taught Tai Chi in his hometown for almost 36 years.

Although the first martial arts (武术) school     2     (found) in 1982 in Ourense, Spain, Jose did not make the trip to Yongnian, China, until 1994     3     (further) his study of Tai Chi. Since then, he     4     (travel) to China over 20 times. Tai Chi is not     5     (simple) a sport for Jose.     6     attracts him most is the Taoist philosophy (哲学) rooted in Tai Chi, of which the main elements consist in the principles (原则) of “softness, slowness, balance and rootedness”.

His martial arts school, which provided introductory programs for     7     (begin), has about 150 students,     8     (range) from children under the age of 5 to senior citizens over 70.

2 . Officials from the Japanese Olympic Committee say they are sparing no effort to(不遗余力) to prepare and announce the Tokyo 2020 Olympic Games in 2021 is going green. The 5,000 medals Japan has made are more special than most.

One new focus of the Tokyo Olympics is to be “sustainable(可持续的)”——to avoid using too many natural resources, so that the games are easy on the environment. As part of this goal, the organizers decided to make all of the Olympic medals out of metal recycled from old electronics.

Almost all electronics are made with small amounts of “precious metals”, like gold and silver. But collecting enough of these metals to make 5,000 medals was a huge challenge. That’s because the amount of metal in each device(设备) is tiny. It would take about 20,000 cellphones to get just 1 kilogram of gold.

Beginning in April 2017, the organizers placed collection boxers around the country, and asked people to turn in their old electronic devices. Soon people began to respond to the initiative(倡议), turning in smartphones, digital cameras, handled games, and laptops. At first, collection went slowly, but soon more and more areas began to take part. By the end, 1,621 local governments had helped out with the collection process.

Then came the job of breaking those devices down into smaller pieces. After being taken apart and sorted, the small electronics were smelted(熔炼) to get all the gold, silver, and bronze elements. This is a tricky job, which calls for careful attention and good skill. It’s also dangerous, because some of the metals and other things aren’t safe for people to touch or breathe.

By the end of March, 2019, the organizers had hit their targets of getting enough metal for the medals. They had collected around 30.4 kilograms of gold, 4,100 kilograms of silver and 2,200 kilograms of bronze. And now all the 5,000 medals are available for the would-be winners.

A new football competition, Man V Fat,     1     (organize) recently in England. Judging from the name,     2     is easy to guess that players can only join if they are fat. They can only win when they lose     3     (pound) after each game. So, the aim of this competition is     4     (get) fat men to do exercise always.

Jay Ali, a bank manager, found it a perfect idea. He said, “I don’t want to go to weight-loss classes     5     almost all participants are women there. And I don’t want to play football with my friends who are all     6     (thin) than me, so this gives me the perfect opportunity to exercise with guys who are the same     7     me. Here, no one judges me, so I don’t have to get     8     (embarrass).” Mr Shanahan from Staffordshire shared the same opinion, “I took part in the competition after getting fed up with (受够) the weight-loss classes which were     9     (main) filled with women.”

It seems that this football competition has offered fat men     10     amazing way to lose weight.

Khamisi Ally Abdi, a 25-year-old African student in Cangzhou Technical College, Hebei Province, has practiced tai chi for two years. Having worshiped kung fu stars such as Bruce Lee and Jackie Chan as     1     child, the Tanzanian understood Chinese kung fu to be a fast-paced attack and defense art before he     2    (arrive) in China, but now he realizes tai chi is different. It is tai chi moves with balance and deep rhythmic breathing     3     allow him to feel the charm of the exercise. It brings peace and     4     (calm) to his mind while building his muscles.

The college, as one of the international exchange centers,     5     (admit) more than 300 international students from over 50 countries since 2016,     6     (main) countries along the Belt and Road, providing a tai chi course for all foreign students.     7     (practice) tai chi has led Abdi to acquire a comprehensive appreciation of this Chinese culture and ideology. He now prefers people     8     (call) him his Chinese name Chen Yanzhi, as the characters of Yanzhi carry the meaning of talented and virtuous. The art has inspired his understanding of China.     9     he is longing for is teaching tai chi in his country and he expresses hope that this magical kung fu can be     10     (benefit) to more people.

9 . 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-kilometre 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 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.

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.
