1 . 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.

2 . Anyone watching the Winter Olympics in Beijing, China over the last few days will have seen lots and lots of snow ----– man-made snow. Since the area gets little natural snow, this is the first time the Winter Olympics is taking place on almost 100% artificial snow.
This year’s Winter Olympics are being held in Beijing, China, and in two areas northwest of Beijing, Yangqing and Zhangjiakou. The areas get cold in the winter, but they don’t get a lot of snow. That’s because they’re not far from the Gobi Desert, and are generally very dry.
That meant some serious changes were needed to hold the Winter Olympics there. China took water from a reservoir which helps supply Beijing’s drinking water and sent it to a nearby river. To carry the water to the mountains for making snow, the country ran miles and miles of pipes. China says making the snow took about 49,000 gallons (185,500 liters) of water. Outside experts say it probably took a lot more water than that.
China hired an Italian company called TechnoAlpin to create the snow. TechnoAlpin created artificial snow at several earlier Winter Olympics. For the snow in this year’s Olympics, TechnoAlpin laid over 40 miles (64 kilometers) of pipe and brought in hundreds of snow-making machines. Even with all of those machines, making the snow for this year’s Games took seven weeks.
It’s useful to be able to make snow when nature doesn’t provide enough. But artificial snow isn’t the same as natural snow, which has more air and less water. An athlete used to natural snow might have to adjust their style on man-made snow.Still, the machines that make artificial snow are quite advanced. They can make several different kinds of snow depending on what’s needed for each sport. For example, the snow they make for downhill skiing is different from the snow made for cross-country skiing.
A few athletes have complained about the snow at this year’s Olympics. Most others say it’s been just fine.
In recent years, it has become more and more common to use artificial snow at winter sports events. That’s true even in places that used to have a lot of snow naturally. Some artificial snow was used in the Winter Olympics in 2010 and 2014 because of warm weather. In the 2018 Games in PyeongChang, South Korea, roughly 90% of the snow was man-made.
As the world warms because of climate change, problems like this are expected to become far more common. Michael Mayr, who leads TechnoAlpin in Asia, says, “You could not have winter sports now without man-made snow.”

3 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your choice of sport might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(高尔夫球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortages in some local areas.
In fact, there are many environment friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a pair of good shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk can regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and control your weight better.
Whatever sport you take up, you can make it greener by using environment friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

A little exercise is better than none
Exercise is good for us. It reduces the risk of dying from all causes, including cancer and heart disease. This is according to the World Health Organisation. But many people who work on weekdays have little time for exercise.
So, they might try to do something to increase their heart rates over the weekend go for a long run, take a bike ride, hike in the mountains or do a strenuous chore around the house, such as raking leaves , shoveling snow or digging a garden.
We sometimes call people who exercise only on Saturdays and Sundays “weekend warriors (战士)”. But is it healthy to avoid exercise during the workweek and then try to fit it all in during the weekend?
A new study suggests that, yes, it is healthy: Even weekend warriors may reduce their risk of cancer and cardiovascular (心血管的) disease.
Australian researchers at the University of Sydney conducted the study. It took place over a nine-year period.
During that time, the researchers looked at the self-reported exercise habits and health examinations of more than 63,000 adults in England and Scotland. Then they connected that information to mortality—or, death—records.
The researchers found that people who exercised only one or two days a week improved their chances of living longer than people who did not exercise at all. Even those who are very overweight—or, obese—could extend their lives by exercising a couple of days per week. Exercises included playing sports and taking a brisk walk.
First, let’s look at cancer. When compared to those who did not exercise at all , weekend warriors had an 18 percent lower risk of dying from cancer.
As for cardiovascular disease, weekend warriors had a 40 percent lower risk of cardiovascular disease than inactive people, or so-called “couch potatoes”. Couch potatoes are people who don’t exercise. They simply sit all day like potatoes.
In other words, their health improves even if they don’t meet the suggested weekly amount of physical activity. However, to be in the best health, Stamatakis says, more exercise is better.
The WHO suggests that the average adult get at least 150 minutes of moderate (中等的) to intense activity per week. For the best results, the organisation suggests 75 minutes per week of vigorous (高强度的) physical activity.
