【推荐1】According to a recent report, about 15% of the people in the UK are members of gyms. But are they more likely to be fit?

A study found that gym members were 14 times more active than people who didn’t belong to any health club. Gym members did six hours more exercise a week, and this activity did make them fitter than non-gym members. They also spent less time sitting down every day than non-gym members. The results were the same for men and women.

The study included 405 people between the ages of 30 and 64, and the main characteristics of those who were gym members were the same as those who were not. “But gym members did more training than non-gym members,” said the lead author, Elizabeth Schroeder of the University of Illinois.

While it might seem clear that gym members exercise more and are healthier than non-members, Schroeder says this has not been directly shown before. However, the study is only designed to show a tie between gym membership and more exercise. It may be that active people like to join gyms. In the study, people who exercised as much as gym members were also in good health.

You can get the same benefits wherever you exercise. This study shows a gym membership can make you do more exercise, but other research shows that exercising outside has other help. Outdoor activity can make you feel happy about lifeespecially if you run through a forest.

Outdoor exercise is also more enjoyable than going to the gym. The first five minutes of outdoor exercise is especially helpful in making people feel good. But Schroeder says that a gym may also encourage greater exercise because it can be social and fun.

【推荐2】Rock climbing is not just for grown-ups. Your children can also enjoy this fun-filled activity as well as getting its advantages. Aside from its heart-health benefit, it is also known   to   increase   their   self-confidence   and   esteem(尊重).   While   it   may   not   be   an impromptu(即兴的) activity like running or biking, there are many climbing walls that are now available, especially with the development of fitness centers and camps.

The great thing about having your kids join these activities is that it follows up on their natural quality. As you know, children are natural climbers. You can see them going up on trees or climbing tall ladders. With rock climbing, you can satisfy their urges to be a climber.

What’s   more,   it is fairly easy for the kids compared with adults. With a high strength-to-weight rate, they have less body weight to pull up, and they are more flexible(灵活的).

It is also a low-impact workout that tests your children’s endurance(耐性). It’s easy on their joints(关节) as they burn energy during their ascent. In addition, climbing walls are like giant puzzles begging to be solved. Not only does it test the physical aspects of your children’s development, but it also wakes their mental abilities.

This exercise also helps develop your children’s essential strength and flexibility. Kids are challenged physically as they pull, lift, stretch, and twist their way up. This activity also develops their eye-hand coordination(协调) as they perform their climb.

Almost anyone can do it although it may vary in skill level, namely beginner, intermediate, or advanced. But despite its reputation as an extreme sport, children can do this. One does not need to be super-fit to join a rock climbing class. However, good technique is more necessary than strength when doing this sport.

【推荐2】Life has gone mostly online for many people around the world. With more people going online during the COVID-19 pandemic, global Internet traffic has become a big problem. Between January and late March, an increase in Internet traffic made many major. cities experience Internet traffic jams.

Video meetings, online classrooms and stay-at-home entertainment have become a daily routine. This increase in traffic is testing the Internet's strength. In March, major phone networks in the UK experienced mass outages（断供）. People were not able to take calls, receive messages or use mobile data.

In the US, major telecommunications companies like AT&T said traffic was up 21 percent month over month. Video streaming services like You Tube, Netflix and Facebook have cut their picture qualities and download speeds. This is being done to reduce network traffic jams.

China has seen an Internet traffic increase of around 50 percent compared to the end of 2019. The country's network speeds went down sharply in early February. However, they returned to normal soon afterwards and have been working well. This is due to China's work in building network infrastructure（基础设施）, especially 5G technology. By the end of February, 164, 000 5G base stations had been built nationwide. This has given Chinese networks the power to handle increased traffic.

“If there were no such development in the Internet network field, people could hardly enjoy such a colorful life at home. Online working and teaching could never be realized so smoothly,” said Wen Kun, an official with the Ministry of Industry and Information Technology.

【推荐3】Many employees must be tempted to query on a daily basis when they see their bosses headed down the wrong track. But caution, for fear of appearing insubordinate or foolish and thus possibly at risk of losing their jobs, often leads workers to keep silent.

A culture of silence can be dangerous, argues a new book, “The Fearless Organization”, by Amy Edmondson, a professor at Harvard Business School. Some of her examples are from the airline industry. One was its deadliest accident: a crash between Boeing 747s in the Canary Islands in 1977 when a co-pilot felt unable to query his captain’s decision to take off based on a misunderstanding of instructions from air-traffic control.

The risks may be lower than life or death in most organizations, but companies also suffer   when people keep silent, Ms Edmondson believes. Volkswagen was caught up in a scandal(丑闻) over diesel(柴油)emissions from 2015. The engines of its diesel models did not meet American emissions standards and engineers devised a system to fool the regulators. Ms Edmondson says the company’s culture had been one based on threaten and fear; Ferdinand Piëch, its longtime boss, boasted of telling engineers they had six weeks to improve the bodywork fitting on pain of dismissal. In the circumstances, engineers were understandably unwilling to mention the bad news on emissions standards and instead worked around the problem. In a corporate culture based on fear and intimidation, it may appear that targets are being achieved in the short term. But in the long run the effect is likely to be counterproductive. Studies show that fear inhibits learning. And when confronted with a problem, scared workers find ways of covering it up or getting around it with inefficient practices.

The answer is to create an atmosphere of “psychological safety” whereby workers can speak their minds. In a sense, this is the equivalent of Toyota’s “lean manufacturing” process, which allows any worker who spots a problem to stop the production line. This does not mean that workers, or their ideas, are immune from criticism, or that they should complain incessantly.

As mundane(平凡的)tasks are automated, and workers rely on computers for data analysis, the added value of humans will stem from their creativity. But as Ms Edmondson’s book amply demonstrates, it is hard to be either constructive or creative if you are not confident about speaking out.

【推荐1】Various sports attract fans for different reasons: Spectator sports draw even more fans who just love to watch. Here are some of the most beloved sports worldwide.

Football, better known as soccer in the US, is by far the most popular sport in the world. Experts estimate that the origin (起源) of football may go as far back as two thousand years, beginning in ancient China during the Han Dynasty. One major reason for football’s global popularity is that, unlike other sports that require expensive equipment, all you need to play football is a ball and your feet.

Volleyball pits two teams across a high net, each attempting to smash the ball onto the opponent’s (对手的) floor. A popular variant, beach volleyball, is competed on sand by pairs rather than the regular six players per team. The crowd appeal of beach volleyball has grown greatly in recent years.

An estimated one billion people worldwide follow professional tennis tournaments and matches. In tennis, players on both sides of a net try to hit a ball with a racket so that it either goes past their opponent or bounces twice on their opponent’s side of the court to score points. Tennis superstars like Rafael Nadal, and Serena Williams are now household names around the world, with huge international fan bases.

Hockey, both on ice and on a field, wins a following of two billion enthusiastic fans worldwide. Field hockey is mainly played in Europe, Africa, Asia, and Australia, while ice hockey is particularly popular in Canada and the US, where kids grow up playing pond hockey. Unlike ice hockey, field hockey usually does not have body contact in the form of checking and hitting.
