Denmark is only about half the size of South Carolina, but it produces more of its electricity from wind than any other country in the world. That's not because it's a particularly breezy country; it has pretty ordinary average wind speeds. The reason the Danes now get 47% of their electricity from wind,with more to come,comes down to a combination of history and policy.
First, the history: Paul la Cour was a scientist and inventor who experimented with and engineered early wind power machines at the start of the 20th century. So it's not surprising that Denmark spent money developing wind power early, beginning at a national level in the 1970s.In the 1980s,due to a strong grassroots movement disagreeing with nuclear power plants, Denmark increased production before many other countries were even considering it.
Denmark has also had significant government support for wind-energy projects, as well as support from the country's technology-focused universities. Even back in 2002, the country was taking climate change warnings seriously, aiming to cut fossil-fuel emissions by 20 percent, which it did via renewable energy investment and implementation.
Some of the world's largest companies in the area --- including Vestas, which builds turbines, and Orsted, which specializes in offshore wind projects --- are Danish,so the country has an impact beyond its borders.
The great impact of Denmark's wind-energy business is important because it's a small country, so while an almost 50% rate of electricity from wind is admirable, it's also small in terms of overall global impact.
While Denmark gets almost half of its electricity needs covered from 5,758 megawatts (MW) of capacity, Spain's 23,000 MTW covers just 18 percent of its electricity supply as it's a much bigger country. China is the leader in wind energy at 221,000 MW,and the U.S. comes second in the world at about 96,000 MW.
Denmark's long support for wind-energy technology and its policies made in support of wind energy have proven this approach can work to decarbonize the economy, even on a bigger scale.At the end of 2019, lawmakers in Denmark set a new goal: increasing the percentage of electricity sourced from renewable power to 100%.

【推荐1】Scientists have found an unexpected use for virtual reality headsets (耳机). The devices (装置), widely used by computer gamers, show pictures that can be used to test the navigational (导航的) skills of people, who were thought to be at risk of dementia (痴呆). Those who do worse in the tests will be the ones more likely to develop Alzheimer’s disease later in life, scientists now believe.
The discovery that the loss of navigational skills was associated with Alzheimer’s was made several years ago by Dennis Chan and his colleagues based at several centers in the UK. These studies used computers to test navigational tasks. But now scientists plan to take their tests to a new level with the use of the virtual reality headsets in which wearers are placed in man-made environments through which they must navigate.
Around 300 people, aged between 40 and 60, will be arranged to participate in the study. Some will have a gene that puts them at risk of the condition or will come from a family with a history of Alzheimer’s. Not all will certainly be affected by the disease, however. Chan’s project aims to find out who will. Wearing the headsets, participants will be asked to navigate their way through a series of different environments and then remember the details.
Researchers recently pointed out the significance of a tiny area of the brain known as the entorhinal cortex (an important memory center in the brain ). It acts as a center in a widespread brain network that controls navigation. This now appears to be the first part of the brain that seems to be easily harmed by Alzheimer’s.
The goal of the work is to help people as they develop the disease. “So far, drug trials for Alzheimer’s have been applied when people have already got dementia, by which time considerable damage to the brain has already occurred,” Chan told the Obsenver. “If we can entorhinal cortex, then this would have the potential to prevent the dementia.”

【推荐2】Earthquake rescue robots have experienced their final tests in Beijing. Their designers say that with these robots, rescue workers will be able to have more time to save more lives during an earthquake.
This robot looking like a helicopter (直升机), is called the detector-bot. It’s about 4 meters long, and it took about 4 years to develop the model. Its main functions (作用) are to collect information from the air, and send goods of up to 30 kilos, to people stuck in an earthquake.
This robot has a high quality 360 degree panoramic camera. It can work day and night and will also be able to send the latest pictures from the quake area. Dr. Qi Juntong, Chinese Academy of Science, said, “Unlike other automatic machines, the most important feature of this robot is that it doesn’t need a distant control. We just set the information of the earthquake-struck area on it, and then it takes off, and lands by itself. It flies as high as 3, 000 meters, and as fast as 100 kilometers per hour.”
This robot has a different function — it can change as the environment changes. Its main job is to search for any signs of life in places where human rescuers are unable to go.
As well as a detector (探测器) that finds victims (遇难者) and detects poisonous gas, a camera is placed in the 40-centimeter-long robot, which can work in the dark.
Another use for the rescuers is the supply bot, with its 10-meter-long pipe. People who are caught in the ruins will be able to get supplies including oxygen and liquids.
Experts have said that the robots will enter production, and serve as part of the national earthquake rescue team as soon as next year.
1. Which of the following statements about the robot is true according to the passage?| A．It hasn’t been put into production so far. |
| B．It is a machine with a length of 10 meters. |

【推荐3】Space travelers on the International Space Station pull twelve-hour shifts(轮班), including six and a half hours of lab work, among other duties. They sleep eight hours, leaving them the other hours to idle in the space. If the timing’s right, they call home to catch up. They watch their schools play football. NASA has sent up playthings like guitars, keyboards, and a saxophone, as well a chess set.
Staying entertained is important because when you’re on long space flights, feeling bored can be dangerous, “It leads to performance errors,” NASA Senior Operational Psychologist James Picano tells me. Breaking a tool is a lot more worrisome when you’re trying to keep a spaceship that weighs hundreds of thousands of pounds on course. In addition, playtime also allows the team to learn pop culture and helps Americans relate to their high-flying stars.
But space travelers might not always have that solid link to Earth. NASA’s plans to go to Mars by 2040 may require a seven-month journey. Maintaining a constant signal over such a vast distance will be tough, but when technology permits, space travelers could watch TV series. NASA is also looking into virtual reality(虚拟现实)so space travelers can spend an afternoon at the beach.
“What will the people we send to space do for fun many years from now, when they’re setting up shop on Mars and the moon?” I ask him. “Boy, I have no idea,” Picano says. But he draws my attention to the South Pole’s McMurdo Station, which once just had a simple bowling alley (保龄球球道)and now has a wine and coffee bar. “We are creators,” Picano adds. “If you send scientists to extreme environments, they will invent ways to stay entertained. It never stops amazing me.”

【推荐1】Scientists have proved that petting cats and dogs for just ten minutes is an effective way to reduce stress levels.
Scientists showed that the general well-being of students improves quickly, with even those who are highly stressed showing ''significant'' reduction in cortisol levels - a chemical produced by our bodies in times of stress.
Many universities have adopted ''Pet Your Stress Away'' programs where students can interact with cats or dogs and it appears to be paying dividends now.
The research, conducted by Washington State University, shows that pets improve students' moods and their presence has stress-relieving physiological benefits. ''Just 10 minutes can have a significant impact, '' said Patricia Pendry, an associate professor in WSU's Department of Human Development. ''Students in our study that interacted with cats and dogs had a significant reduction in cortisol, a major stress hormone. ''
This is the first study that has demonstrated reductions in students' cortisol levels during a real-life intervention. The team chose 249 college students and put them into four random groups and compared the effects of different exposures to animals.
The first group were provided 10 minutes of hands-on interaction with dogs and cats.
The second group waited in line while observing others petting the animals.
The third group watched a slideshow of the same animals, while the fourth group was ''waitlisted. ''
Salivary cortisol samples were collected from each participant starting from the moment they woke up in the morning.
There were significantly less cortisol in the saliva of students who had direct interaction with the pets.
''We already knew that students enjoy interacting with animals, and that it helps them experience more positive emotions, '' Dr Pendry said.
''What we wanted to learn was whether this exposure would help students reduce their stress in a less subjective way. ''
''And it did, which is exciting because the reduction of stress hormones may, over time, have significant benefits for physical and mental health. ''
1. What can we learn from the passage?| A．The more stress you have, the less cortisol your body produce. |

【推荐2】A small sensor (传感器) worn on the neck containing wires can monitor how much we move while sitting too long, and encourage people to get up and exercise.
Nowadays more and more people experienced neck and shoulder pain — a problem of the changing way we work. But moving regularly while sitting can prevent problems.
Zhengbao Yang at City University of Hong Kong and his colleagues have developed small, stretchable sensors that are powered by electricity-charge that is generated through squeezing or stressing suitable materials.
The sensor monitors the movement of the neck and is powered by two layers of piezoelectric (压电的) material folded in a structure from kirigami, which is related to the art of paper folding. When the wearer moves, the sensor changes its shape and sends charge to a microcontroller that can register the movement with an accuracy of 95 percent, displaying this on a computer. “We can use this material to change stress into voltage (电压), then we can measure the joint motion by using that,” says Yang. If the wearer doesn’t move his/her neck or shoulder more than 10 times in every half hour, a prompt is displayed on the computer.
“The sensor offers a new and novel design within a small package which is perfect for the placement on the body,” says Jonathan Aitken at the University of Sheffield, UK. “The sensor clearly succeeds in the general aim to indicate inactivity, although it would be interesting to research further into its characteristics, reliability and sensitivity.” Aitken says this could help generate more accurate monitoring of motion that would make the sensor more powerful.
For Yang, the sensor could move from the lab to real life as it is. “We already have a patent (专利) on this technology,” he says. “We’re thinking about how to license this patent to local industry, to bring benefits to society.”

【推荐3】One Sunday in 2021, when my son, Leo, was six, we ran into one of his friends, Izzie. They decided to play ——but what? “I have a great idea,” Leo said. “Let’s fall in love! OK?” Izzie took a half-second to consider this proposal, then replied “No.” She wanted to play tag.
Leo has always been the kind of child who looks for close connections, often in the wrong places. It sometimes feels as though he’s been looking for a soulmate since he was a toddler（学步孩童）.
One day, he came home from school and immediately grabbed his iPad to ask Siri: “Can you fall in love when you’re just a kid?”
Siri, Apple’s voice-controlled personal assistant, is great at opening apps or setting alarms, but I was unfamiliar with her philosophies on love.
“What did Siri say?” I asked him.
“She said, ‘Here’s what I found on the web!’” Leo reported.
This was hardly the first time I’d heard Leo in conversation with Siri. Over the years, he’s relied on Siri as a source of comfort, advice, emotional support, and guidance. Their relationship blossomed when the pandemic forced us all to shelter in place.
At first, Leo mostly asked Siri factual questions, then the personal ones. As time passed, he began to engage on more existential matters. Siri has, in some ways, been able to absorb some of Leo’s concerns—in a way that, as his mother, I can’t, at least not with the same coolness.
Children are overwhelmed with emotions such as grief, fear, love, and a desire for connection. If Leo’s talks with Siri confronted me with the unknowable and unanswerable, they also made me frustrated at my own limitations as a parent.
There are many challenges to parenthood, among which the biggest is the desire to shelter our children from the painfulness of reality. But helping our children navigate reality is surely more helpful than sheltering them from it. Perhaps the best we can do is give them a tablet?
I’m afraid I don’t have the answer. Maybe I should ask Siri.

【推荐1】Ida Nelson was luxuriating in her sauna(桑拿)when she heard the thunder of a small airplane circling the nearby airport. It was 11:30 at night in the Alaskan village of Igiugig, population 70, and, as she told the New York Times, “Any time a plane flies over that late, you know something is wrong.” Nelson leaped out of the sauna, ran to the window, and saw the problem: The airport’s runway lights were out.
Nelson threw on some clothes, jumped into her ATV, and floored it to the airport, where she found a local pilot trying to turn on the lights manually. “Normally, if you push the button 10 or 15 times, the lights will just light up,” Nelson said. Not this time. Meanwhile, she and the pilot learned of the plane’s urgent mission: It was a medevac( 医疗后送直升飞机 ), there to transport a seriously ill local girl to the nearest hospital, 280 miles away in Anchorage.
Nelson had a plan. Driving her ATV to the end of the runway, she switched her headlights on for the plane to follow. Great idea, but it wasn’t enough. More light was needed, so a neighbor called nearly every home in the village—32 of them. Within 20 minutes, 20 vehicles arrived at the airport, many of the drivers still in pajamas( 睡衣 ). Following directions from the medevac pilot, the cars lined up on one side of the runway.
The medevac made its final approach and, guided by the headlights, landed safely. The young patient was loaded onto the aircraft, and the plane immediately took off again. Her illness was never publicly revealed, but she has since been released from the hospital.
In a world filled with uncertainty, the little community’s positive activism is a big deal. Not so much for Nelson. As she told CNN, in Igiugig, coming together is “kind of a normal deal”.

【推荐2】European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future.
Researchers from the European Space Agency, or ESA, carried out the experiments at a laboratory in the Netherlands. They reported their results in a study published in Planetary and Space Science.
The team says ESA’s experimental “plant” was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith (月壤)，a top layer of dirt and rock pieces that sit on the surface of the moon.
Samples of regolith from the moon have confirmed that the material contains about 45 percent oxygen by weight. However, the oxygen is chemically locked in the form of minerals or glass, so it is not easily available for use. Having real samples of regolith from the moon made it possible for the researchers to create the simulated moon dust material used during testing.
The oxygen extraction (提取)process is carried out using a method called molten salt electrolysis (熔盐电解). This involves first placing the regolith in a metal container. Calcium chloride salt is added to the mixture, which is then heated to 950 degrees Celsius. At this temperature, the regolith remains solid. Next, an electrical current is passed through the material. The researchers say it is this step that results in oxygen being extracted from the regolith. The study reported that up to 96 percent of oxygen in the simulated moon dust was extracted during the experiments.
ESA’s long-term goal is to design an oxygen -producing “pilot plant” to operate full-time on the moon. The first technology demonstration of the system is expected to take place in the middle of 2020s.
The researchers reported that “as a bonus”，the process also results in the production of usable metallic materials.

【推荐1】[1] In 1856, a British survey team measured the height of Qomolangma with the result of 8,840 meters above sea level. However, the exact measurement has never been settled. In 1955, the figure was adjusted by an Indian survey team to 8,848 meters, and later to 8,850 meters according to a US team in 1999. And in 2005, a Chinese team gained a height of 8,844 meters, but that result wasn't widely accepted either.
[2] On May 6, 2020, a 30-member Chinese survey team, equipped with the latest technology, including a Global Navigation Satellite System receiver and a radar to measure the mountain's snow cap, is determined to settle the dispute (争议).
[3] But measuring Qomolangma is no easy task. The average air temperature there is -29℃ and hurricane-like winds blow all the time. According to Li Guopeng, leader of the No.1 Geodetic Survey Team of China's Ministry of Natural Resources, despite advanced technologies we now have — the likes of robots and drones — it’s uncertain that they can operate smoothly under extreme conditions, which is why sending human experts to the peak is still necessary to ensure a precise reading.
[4] But ______
[5] The truth is that measuring the height of Qomolangma is much more than just getting that one particular number. Mount Qomolangma is the perfect window for observing crustal (地壳的) movements. Tiny changes to the peak's height can indicate whether the two plates, the Eurasian plate and the Indian plate, are heading toward or away from each other. The survey team will also get firsthand information about the condition of the snow and other natural materials at the top, which could be an indicator of climate change on the Tibet-Qinghai Plateau.
[6] It might be true that settling a dispute was the driving force for continued exploration, but the good thing is that we always end up discovering so much more.

【推荐2】Chinese Paper Cutting or Jianzhi is the first type of paper-cutting design, since paper was invented in the Eastern Han Dynasty in China.
It’s a very distinguishing visual art of Chinese handicrafts. The art form later spread to other parts of the world with different areas adopting their own cultural styles. After hundreds of year’s development, now they’ve become a very popular means of decoration among country folk, especially women. The paper-cuts are also used to decorate doors and windows, and therefore they’re sometimes referred to “chuang hua”, meaning Window Flower. Paper-cuts are chiefly used as decorations. However, today, Chinese paper-cuts are also used for religious and ceremonial purpose, and they’re buried with the dead and burned at funerals.
Chinese people believe the red paper-cuts on the door can bring good fortune and happiness to the whole family. The paper-cuts are more often seen during traditional Chinese festivals, particularly in Chinese New Year, the Spring Festival. They’re also given as gifts to friends or other family members.
Paper-cuttings aren’t produced by machine, but by hand. There’re two methods of manufacture: one uses scissors, the other uses knives. Knife cuttings are fashioned by putting several layers of paper or a relatively soft foundation. Following a pattern, the artist cuts the motif into the paper with a sharp knife he usually holds vertically. The advantage of knife-cuttings is that considerably more paper cuttings can be made in one operation than with scissor cuttings.
It’s easy to learn about cutting a piece of paper but difficult to master it with perfection. One must grasp the knife in an upright fashion and press evenly (均匀地) on the paper with some strength. Flexibility is required but any hesitation will damage the whole image.
People find hope and comfort in expressing wishes with paper-cutting. For instance: for a wedding ceremony, red paper-cuttings are a traditional decoration on the tea set, the dressing table glass, and on other furniture. A big red paper character “Xi” (happiness) is a traditional must on the newlywed’s door.
