1 . The idea of billions of people going through a few masks a week during this pandemic definitely rings alarm bells, but a team of researchers in Melbourne may have the solution.
They’ve discovered that adding millions of discarded face masks to road-paving (铺路) mixtures would actually lower the cost of the road, while preventing billions of them from landfills. Just one kilometer of road would need three million masks, and the polypropylene (聚丙烯) plastic used to make single-use surgical face masks also increased the flexibility and durability of the road.
The new material is a mixture of about 2% torn masks, with recycled concrete aggregate (RCA)—a material obtained from waste concrete and other minerals from destroyed buildings. This recycled material was found in the study to be ideal for two of the four layers generally required to create roadways. Paving a kilometer of two-way road with the RCA and three million face masks would result in a change of 93 tons of waste from landfills.
The final product then is more resistant to wear than asphalt (沥青), as well as being cheaper too, provided there was a method for collecting masks. The research team did a cost-analysis and found that, at $26 per ton, the RCA was about half the cost of mining raw materials, and as much as a third of the cost of shipping the used masks to a landfill.
The widespread application would be ideal for large infrastructure (基础设施) projects. For example, Washington has the 11th worst roads in terms of unaddressed repairs in the U.S. If the damaged roads in Washington state were repaired with the RCA/mask mixture, it would reuse nearly 10 billion masks, sparing American landfills hundreds of millions of tons of trash.
It’s said that the team is looking for private industry partners or governments willing to give their plastic mask road an opportunity for a large-scale test.

2 . Arguster grew up on his family’s farm in a remote village. Planting cash crop — cotton, they were breaking even and had to make ends meet. In his childhood, there were nine kids at home. All the boys were in one room with two beds. Two slept at the head while two slept at the foot. Therefore, there was one thing about their feet — washing them before crowding onto the bed.
When there was a hole in Arguster’s jeans, his mother would put a patch on it. However, the hole kept going. It was the naughty kids, Arguster included, that took the jeans out, hung them on a line and shot them to put holes. Aware of that, however, Ben, the father, didn’t rebuke them, knowing it might be the only way to bring laughter to his kids.
Arguster’s first lesson in economics was taught by Ben. The childish kid had worked and made a little extra money. He couldn’t help admiring himself, “I make six dollars! Six dollars! Man! I’m on the top of the world!” With a great thrill, Arguster decided to go to fair, where he played games, ate cotton candy... When asked by Ben how much he had spent, with his head down, Arguster replied, “Daddy, I spent it all...” Looking at his messy hair, Ben sighed, “Boy, you spent all your money and haircut’s gone up to 75 cents. I’m afraid...” From then on, Arguster always kept enough money to get himself a haircut.
Ben taught his kids how to do the right thing and wanted them to do the right thing, which Ben tried to pass on to his kids, in his own way. Ben started a syrup mill(糖坊). People in the community brought their cane and millet for Ben to grind up (磨碎) for syrup. When people paid with buckets of syrup, Ben refused. Arguster got confused, “Daddy, why don’t you let these people pay you?”
“Because we got enough syrup to last for a long time! Son, these people don’t have money to pay. That’s the only way they can pay.”

3 . An international group of electronic music composers is taking beats from the dance club to jungles and forests and back, all to help save nature's greatest singers. A Guide to the Birdsong of Mexico, Central America and the Caribbean is a new album that includes the sounds of endangered birds. The album will come out next month, whose proceeds will go directly towards efforts to save birds.
The whole project was born out of this idea of trying to combine birdsong, electronic music and conservation. A Guide to the Birdsong of Mexico, Central America and the Caribbean was organized by activist, music producer, Robin Perkins. He invited artists from each of the endangered birds 'homelands to build their own songs around the birds’ songs. There are contributions from ten artists in eight different countries.
First single Black Catbird was created by The Garifuna Collective, from Belize. Al Obando, guitarist and producer of the group, always took in national parks and viewed birds when on the road with the band. “There are no trails, and there are no signs there to tell you about what you reseeing,” Obando says. “So we're trying to do something for the birds and nature tourism.”
Another musician who responded to Robin's call is Tamara Montenegro, an artist from Nicaragua. She was shocked to hear of the serious situation of the Guardabarranco after being approached: “This beautiful creature I grew up adoring also faced the influence of the systematic human activities”. In response, she created a song inspired by this bird and the challenges it faces to live naturally.
The new album is the second edition, following on from A Guide to the Birdsong of South America, produced by Robin in 2015. That first album has raised, to date, over $15,000 benefitting conservation projects in South America. As with the first album, all of the money from the sales of the new album will support specific organizations, including Birds Caribbean.

4 . A Universal Greeting: Shaking Hands
A handshake seems to be a normal gesture. In fact, in the 9th century BC, an ancient site during the ruling of Shalmaneser III clearly shows two figures holding hands.The Iliad,usually dated to the 8th century BC, mentions that two characters “taking each other's hands and expressing their loyalty," Centuries later, Shakespeare once wrote of two characters who shook hands and swore to be brothers in the bookAs You Like It.Shaking hands seems to be an ancient custom whose roots have disappeared in the sands of time.
Historians who have studied ancient etiquette books note that the modern handshake did not appear until the middle of the 19th century, when it was considered a slightly inappropriate gesture that could only be used between friends. But what if Shakespeare had written about handshaking hundreds of years earlier?
According to author Torbjorn Lundmark in hisTales of Hi and Bye: Greeting and Parting Rituals Around the World,the problem comes in differing definitions of the handshake. The early handshakes mentioned above were part of making deals or peace; King Shalmaneser 111 referred to a rebellion in which he signed a treaty with the King of Babylon. In theIliad,Diomedes and Glaucus shook, hands when they realized they were guest-friends, and Diomedes declared: "Let's not try to kill each other." Shakespeare was similarly referencing settlement of a conflict.
The modern handshake as a form of greeting is harder to trace. As a Dutch sociologist Herman Roodenburg — the chief authority for the history of handshaking — wrote in a chapter of ananthologycalledA Cultural History of Gesture,“More than in any other field, that of the study of gesture is one in which the historian has to make the most of only a few clues”.
One of the earliest clues he cites is a 16th-century German translation of the French writer Rabelais'sGargantua and Pantagruel.When one character meets Gargantua, Rabelais writes, “He was greeted by countless hugs and countless good days." But according to Roodenburg, the 16th-century German translation added references to shaking hands.
A popular saying suggests that Cleland's statements against bowing were actually a wish to go back to a potentially traditional method of greeting in Europe. As the centuries progressed, handshaking was replaced by more hierarchical ways of greeting — like bowing. According to Roodenburg, handshaking survived in a few remote places, like in Dutch towns where some would use the gesture to make peace after disagreements. Around the same time, those who valued equality also made use of handshaking. Then, as the Continent's hierarchy was weakened, handshaking became a common practice among people of the same rank, as it is today.

5 . When Chef Enrique Olvera opened his restaurant, Pujol, 13 years ago, his only goal was to have the best restaurant in the neighborhood. Olvera's budget was so small that he had to do all the things himself. But Pujol is now widely thought of as Mexico's finest restaurant and the 36th best in the world. He reached his position by making his cuisine 'fancier and fancier, and more complex' over time. Pujol now serves a tasting menu of sophisticated food that wouldn't look out of place even at New York's Momofuku Ko. To decode his rocket soar in world cuisine circus, Olvera insists on mixing elaborate, cutting-edge techniques with a strong emphasis on local ingredients to create a cosmopolitan cuisine that's at once international yet unmistakably Mexican, matching the direction of Mexico City itself.
A visit to the 48-seat Pujol reveals a space-age kitchen containing 27 cooks, with one making his fifth attempt to reshape the egg liquid and another coloring potatoes. Pujol tolerates any grotesque attempt a chef could imagine and the restaurant is the trial site for its staff. That makes Pujol a hot place to attract free labor. The chef has also thought more about bringing Mexican cooks home from the U.S. Many are returning to move past the glass ceiling that exists in America. “Despite the number of Mexicans working in U.S. restaurants, you rarely see a Mexican head chef in a New York kitchen,” said Olvera. “Then why not come back here to attract diners here for the most local but also novel dishes?”
And for foreign diners, Mexican restaurants have another wonder to offer. Just think that merely 30 dollars can sustain you for a 4-course feast in an ordinary Mexican restaurant and no one could resist the temptation. To achieve such high cost performance, Olvera states that you have to keep looking for and exploring with the simple ingredients from which to accomplish amazing dishes. “You always cherish where you come from, but there’s also the need for new sensations. Keep exploring with new ideas until you get a better dish.” After all, it’s the soul of modern cuisine.
1. Why has Pujol become so successful?| A．Because Olvera aimed low in the first place. |
| B．Because Olvera forms the habit of doing things by himself. |
| C．Because Olvera attracts excellent cooks from the U.S. |

| B．Olvera relies totally on foreign cutting-edge cooking techniques. |
| C．Eating in ordinary Mexican restaurants is expensive. |
| D．One key to success in today’s restaurant business is continuous innovation. |
6 . The Sanxingdui Museum in southwest China’s Sichuan Province enjoyed huge popularity during the three-day Qingming Festival holidays by receiving nearly 20,000 visitors on the peak day, after the new archaeological discoveries brought international attention.
According to media reports, the museum saw over 15,000 visitors on Saturday, the first day of the Qingming Festival, breaking its record for daily visitors. And on the next day, more visitors swarmed into the museum to exceed 19,800. To cope with the large flow of people, on Sunday afternoon, the official Weibo account of the Sanxingdui Museum released the message to remind visitors of avoiding rush hours or rescheduling their visiting time.
The Sanxingdui Museum showcases various kinds of precious cultural relics unearthed at the site, such as the 2.62-meter-tall standing statue, 1.38-meter-wide bronze mask, 3.95-meter-high bronze tree. Earlier on March 20, Chinese archaeologists announced some new major discoveries made during the 37th excavation (挖掘) since its last excavation 35 years ago. The ruins were first discovered in the late 1920s and first excavated in 1934.More than 500 important cultural relics have been unearthed in the six newly-found pits. Since the new discoveries were known to the public, the number of people visiting the Sanxingdui Museum has increased sharply.
The museum said although they are open as usual, the newly-found pits have not opened to the public yet and the newly-excavated cultural relics are still under restoration and cannot meet the public currently. But a hall for cultural relic conservation and restoration will be in pilot operation in April and officially open on May 18. Visitors to it can see how the relics are restored, according to Zhu Yarong, vice director of the Sanxingdui Museum.
Dating back about 3,000 years, the Sanxingdui Ruins have shed light on the ancient Shu civilization and cultural origins of the Chinese nation, and have been regarded one of the most important archaeological discoveries in the 20th century.

7 . Each generation -- from Baby Boomers to Generation X to Millennials -- has its own set of values and characteristics. But one thing common to all generations is that they are suffering from stress. In a recent poll by the American Psychological Association (APA), all age groups now report higher levels of stress than in the past. Baby Boomers (those born roughly between 1946 and 1964, and who are now moving into their retirement years) said that they are stressed about earnings and health issues. Gen Xers (born roughly between 1965 and 1980) are concerned about work, income, and job stability. However, Millennials (born roughly between 1981 and 2004) are turning out to be the most stressed-out of all the generations. Poll results indicate that stress levels for these younger respondents are significantly above average. So what’s worrying the Millennials?
Millennials are the first generation to grow up with computers in the home and the classroom. Due to the rise of modern technology and social media, they are constantly showered with information. Over time, this information overload can become too much to handle and can result in stress, which in turn can cause serious physical, psychological, and emotional problems. Another contributing factor, according to author Michael D. Hais, is that many Millennials have lived sheltered lives due to overprotective parents. These young adults lack problem-solving skills and may struggle with fear of failure once they leave home. Making matters worse, the 2008 economic depression occurred when many Millennials were graduating from high school or college. The resulting economic slowdown reduced the number of available jobs for graduates. Sure enough, in the APA poll, Millennials said that work, money, relationships, family responsibilities, and the economy are the main stressors in their lives.
However, the poll results may be a bit misleading as they don’t take into account public attitudes toward stress and mental illness. Ronald Kessler of Harvard Medical School, who has studied the prevalence (流行) of mental disorders in the U.S., points out that changes in social attitudes have helped reduce the stigma attached to mental illness over the years. For example, the creation of health-related television programming and specialty magazines such as Psychology Today have contributed to greater public awareness of mental health issues. According to psychologists, younger people now are more willing to admit to them that they are under stress than in the past. “There is not a lot of evidence of true prevalence having gone up,” Kessler says. “It looks like younger people are in worse shape, but unfortunately, we just don’t know.”

8 . There are many therapies (疗法) for depression, including medical treatment, psychotherapy and talk therapy. Having a range of treatment choices is a good idea because no single treatment works equally well for each of millions of sufferers. Choosing the most suitable treatment is important to them. Now researchers say a new therapy proven to relieve depression should be added to the established treatments. It's called nature therapy. "Interacting with nature can have positive effects on those with depression," says Ethan Kross, PhD, an expert who has studied the nature depression link.
A little exposure to nature helps all of us get our energy back, and it may have special benefit for those who are depressed.“It seems that, from our work, the restorative effect of nature seems to be stronger for individuals with depression," says Marc Berman, PhD, an assistant professor of psychology at the University of Chicago. That might be because they feel mentally exhausted, and being in nature re energizes them. However, Dr Berman has a strong warning. “We're not arguing that interacting with nature should replace clinically proven treatments for depression," he says, “Nor should those with clinical depression try to treat themselves.”
However, Berman and others say, interactions with nature could serve as a very effective supplementary treatment. Compared to adults with depression walking for 50 minutes in an urban setting, those who took a 50 minute walk in a natural setting were less depressed and had better memory skills.
Why does nature hold this special effect? Berman says, “In a natural environment, we can choose to think or not, and this choice is believed to help us rest our brains. You can then pay attention later, when you need to.”He adds, “It gives people more ability to concentrate, which is a big problem for those with depression. ”Nature provides an effective setting for resting our brains, unlike urban setting. Even in the most peaceful urban environment, you have to pay attention to such things as traffic and stoplights.
