2 . The Biggest Stadiums in the World
People have been pouring into stadiums since the days of ancient Greece. In around 80 A.D., the Romans built the Colosseum, which remains the world’s best known stadium and continues to inform contemporary design. Rome’s Colosseum was 157 feet tall and had 80 entrances, seating 50,000 people. However, that was small fry compared with the city’s Circus Maximus, which accommodated around 250,000 people.
These days, safety regulations-not to mention the modern sports fan’s desire for a good view and comfortable seat — tend to keep stadium capacities (容量) slightly lower. Even soccer fans tend to have a seat each; gone are the days of thousands standing to watch the match.
For the biggest stadiums in the world, we have used data supplied by the World Atlas list so far, which ranks them by their stated permanent capacity, as well as updated information from official stadium websites.
All these stadiums are still functional, still open and still hosting the biggest events in world sport.

4 . Why Is Exercise Cool?
•Exercise Strengthens Muscles
Did you ever do a push-up or swing across the monkey bars at the playground?
•
Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion”, which means you can move your arms and legs freely without feeling tightness or pain.
•Exercise Keeps the Balance
•Exercise Makes You Feel good
It feels good to have a strong, flexible body that can do all the activities you enjoy—like running, jumping and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.
But you may not know that exercising can actually put you in a better mood.
A.Exercise Makes You Flexible |
B.Exercise Makes Your Heart Happy |
C.Those are exercises that can build strength. |

6 . 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.

7 . On a bright early summer morning, many young swimmers gather at a local swimming pool in the state of Maryland. They are members of a competitive summer swim team, and that’s a regular part of their daily life. As they train and cut seconds off their times, which makes them closer to the championship in the following large-scale (大规模的) competitions, they are getting lots of physical exercise and vitamin D from the sun. However, the benefits of belonging to a sports team are not just honor or health related. You can learn useful life skills.
Paul Waas, coach of the swim team, explains, “The discipline (自制力) comes into play when you’re talking about concentrating on the details that your coaches are saying as it makes you faster rather than going up and down the pool the same way you have every time. When you focus on what you’re doing right and what you can do better, then you’ll see the improvement.”
Besides, there is also responsibility, goals and workings within a group. Again, here is Coach Waas. “It’s really great! It’s so fun to watch from year to year. I’ve had kids who as 7-year-olds on the team could barely pay attention in practice and were only interested in who was going first. Now they’ve come back as 8-year-olds, having set some goals and having things that they want to achieve. These skills can help them a lot.”
But playing the sports is not without harm. Some can be hard on the body. Young athletes suffer serious injuries that follow them into adulthood. Coach Waas says that in fact, swimming is different from most others. First, it poses a lower risk of injury. The second one relates to how swim teams are structured. Actually, children are not the only ones who can benefit. Adults can also benefit from team sports.

10 . If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers and non-joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non-joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”
The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and long-distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study, “You don't actually have to do that much to have a good impact on your health. And perhaps you shouldn't actually do too much.”
