A visually-challenged man from Beijing recently hiked (徒步) 40 days to Xi'an, as a first step  (journey) the Belt and Road route (路线) by foot. 

On the 1,100 kilometer journey, the man Cao Shengkang,  lost his eyesight at the age of eight in a car accident, crossed 40 cities and counties in three province. Inspired by the Belt and Road Forum for International Cooperation  (hold) in Beijing, Cao decided to cover the route by hiking as a tribute (致敬) to the ancient Silk Road.  friend of his, Wu Fan, volunteered to be his companion during the trip. 

Cao and Wu also collected garbage along the road, in order to promote environmental  (protect). Cao believes this will make the hiking trip even more  (meaning). The two of them collected more than 1,000 plastic bottles along the 40-day journey. 

In the last five years. Cao  (walk) through 34 countries in six continents, and in 2016, he reached the top of Kilimanjaro, Africa's  (high) mountain. 

Now, Cao has started the second part of his dream to walk along the Belt and Road route. He flew 4, 700 kilometers  Xi'an to Kashgar on Sept. 20,  (plan) to hike back to Xi'an in five months.

    Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture?

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleeps fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey (冰球) final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning. Thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

    It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

    Feet help us walk, run, dance, and jump. The words feet and foot are also used in everyday speech.

    To be under someone's feet means to be troublesome. In other words, you are standing too close to someone and are getting in their way. Some adults criticize (批评) children for being under foot.

    Speaking of children, if someone says their home will soon have the pitter-patter of tiny feet, it means the family is expecting a baby!

    Now, people who are active do not let grass grow under their feet. They are never in one place for very long. People who can think and take action at the same time are said to be able to think on their feet.

    Some people appear to have it all. They have money, a good education, good looks, a great family and a large circle of friends. You could say they have the world at their feet. This means whatever they want seems to be there for them.

    People who have both feet firmly on the ground are realistic and practical. They are not dreamy. You might say such a person is well grounded. If you are a bad dancer, you might be described as having two left feet. To dance well, it is better to have a right foot and a left foot.

    Sam loves skiing. He thinks that it would be fun to own a ski resort (滑雪场) high in the mountains. But he knows nothing about running a business. So, he decides to get his feet wet. In other words, he wants to get used to a new situation.

    He joins an organization for resort owners and attends their meetings. He travels to ski areas all over the United States. This helps Sam get his foot in the door. Having a foot in the door is a starting point. This expression comes from people selling things door-to-door. They would block the door with their foot so people couldn't close the door on them.

    In a world with limited land, water and other natural resources (资源), the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

    Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油), which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

    The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

    Anyone watching the autumn sky knows that migrating birds fly in a V formation, but scientists have long debated why. A new study finds that these big-winged birds carefully position their wingtips and flap(拍动) at the same rate, probably to catch the upward movement of air and save energy during flight.

    There are two reasons birds might fly in a V formation: It may make flight easier, or they're simply following the leader. Squadrons(中 队) of planes can save fuel by flying in a V formation, and many scientists suspect that migrating birds do the same. Models that treated flapping birds like fixed-wing airplanes show that they probably save energy by drafting off each other, but currents created by airplanes are far more stable than those coming off of birds.

    Just as aerodynamic(气动力) calculations would predict, the birds positioned themselves to fly just behind and to the side of the bird in front, timing their wing flaps to catch the uplifting eddies(涡流). When a bird flew directly behind another, the timing of the flapping reversed(相反) so that it could minimize the effects of the downdraft coming off the back of the bird's body. “We didn't think this was possible,” Usherwood says, considering that the difficult achievement requires careful flight and incredible awareness of one's neighbors. “Perhaps these big V formation birds can be thought of quite like an airplane with wings that go up and down.”

    The findings likely apply to other long-winged birds, such as pelicans and geese, Usherwood says. Smaller birds create more complex wakes(尾波) that would make drafting too difficult. The researchers did not attempt to calculate the birds' energy savings because the necessary physiological measurements would be too invasive for an endangered species. Previous studies show that birds can use 20% to 30% less energy while flying in a V.

    Scientists do not know how the birds find that aerodynamic sweet spot, but they suspect that the animals line themselves up either by sight or by sensing air currents through their feathers. In future studies, the researchers will switch to more common birds, such as pigeons or geese. They plan to investigate how the animals decide who sets the course and the pace, and whether a mistake made by the leader can ripple through the rest of the flock to cause traffic jams.

    City trees grow faster and die younger than trees in rural forestry, a new study finds. Over their lifetimes, then, urban trees will likely absorb less CO2 from the air than forest trees.

    As we all know, the earth would be freezing or burning hot without CO2. However, CO2 is a greenhouse gas, meaning it traps energy from the sun as/heat. That makes temperatures near the ground rise. Human activities, especially the widespread burning-of fossil(化石)fuels, have been sending extra greenhouse gases into the air. This has led to a rise in average temperatures across the globe.

    Studies had shown forests readily absorb CO2, but there hadn't been much data on whether city trees grow, die and absorb CO2 at the same rate as forest trees do. So some researchers decided to find out.

    To figure out how quickly trees were growing, researchers tracked their diameters (the width of their trunks) between 2005 and 2014. A tree's diameter increases as it grows, just as a person's waist size increases as they gain weight. About half the weight of a tree is carbon, research has shown. Most of the rest is water. Over the nine years' tracking, the researchers found city trees absorbed four times as much carbon from the air as forest trees. However, they were twice as likely to die. So over the lifetime of each type of tree, forest trees actually absorbed more CO2.

    City trees grew faster because they had less competition for light from their neighbors. In a forest,trees tend to grow close together,shading their neighbors. Street trees also benefit from higher levels of nitrogen (氮)in rainwater. Nitrogen helps plants grow. Waste gases from gas-burning cars also contain nitrogen, thus enriching city air with nitrogen. Later, rainwater may wash much of it to the ground. Some street trees may also have better access to water than trees in the country because the underground water pipes can leak.
