1 . Instantly, we were busily preparing for the worst. The whole family had experienced such a storm before and everyone remembered the damage it had caused to stock and crops. There was very little we could do about the crops. But we needed to protect the animals in case the river flooded again. My older brother called his sheep-dog and began driving our small flock of sheep to higher ground above river. If the river flooded, they should be safe there.
The underlined word “stock” in the paragraph above refers to _______.| A．money owned by the family | B．goods for sale |
| C．supplies for family use | D．farm animals |
2 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.
The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.
The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.
Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.
“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.
“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

3 . 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.

4 . It is sometimes jokingly said that you may skip a meal a day without any adverse effect but skip using your WeChat for an hour and you will feel distinctly unwell. It is an acknowledgement of the fact that the app is no longer only a fun tool but an essential part of life for millions.
Launched in January 2011, this messaging, social media and mobile payment app today has more than 1 billion individual users. People use it for everything, from applying for a business license to booking a hospital appointment to keeping up with family and friends, shopping and paying bills—activities that are part and parcel of our everyday life.
When it was first introduced, WeChat was only an app supporting voice, video, picture and text messages between two persons or among a group. But today it has become ubiquitous.
In the past, people carried their wallet and keys with them wherever they went; today, a smart phone with WeChat installed is all they need in daily life. Its functions like Moments and mini programs and the official WeChat accounts of government agencies and companies have made communication and public services accessible and convenient like never before.
WeChat is also widely used by enterprises. Figures from Tencent show there are around 15 million WeChat official accounts, which enjoy 5 billion followers. Most businesses use their WeChat groups as a standard marketing kit. This has immensely reduced advertising, marketing and communication costs, and in the background of the novel coronavirus disease, made operations faster, contactless and safe.
However, there are concerns about the downsides of WeChat, such as addiction among primary school children. Equally serious is the misuse of WeChat for fraud or instigating crimes. However, it has to be kept in mind that these fallouts are not really the fault of WeChat, but due to the misuse of the app.
If we learn to temper our use of messaging apps with prudence and pragmatism, we could be looking forward to yet new conveniences and experience in this decade with the rapid development of 5G technology and artificial intelligence. Ultimately, the choice is ours, whether to use WeChat or any other new invention, wisely or wantonly.

5 . A Teacher’s Lifesaving Call
In the midst of the COVID-19 pandemic, Julia Koch began what was only her second year as a first grade teacher in a virtual classroom.
One September afternoon a few weeks into the school year, she received a call from Cynthia Phillips, who was having technical difficulties with her granddaughter’s tools for online learning.
Koch immediately knew something was wrong with Phillips. The two women had spoken numerous times before, but Koch had never heard the grandmother sound quite like this. Her words were so jumbled that Koch could barely understand her, though she was able to make out that Phillips had fallen four times that day.
Koch called her principal, Charlie Lovelady, who assured her that he would call and check on Phillips himself.
Just like Koch, Lovelady could barely understand Phillips. He suspected she might be having a stroke—he recognized the signs from when his own father had suffered one. Lovelady was able to make out the word “kids” and immediately became concerned that Phillips’s two grandchildren, aged six and eight, were probably home alone with her—she is their primary guardian—and scared. Lovelady asked his office manager to send an ambulance to the grandmother’s home. Then Lovelady called two deans in the school district, to tell them what was going on, both of whom dropped everything and drove to the family’s home.
When they pulled up less than ten minutes later, the EMTs(急救人员)were treating Phillips while the two girls, looking visibly shaken, were outside with a neighbor.
The quick response from Koch and Lovelady saved Phillips’s life. She arrived at the hospital in time to get treatment and before chronic damage occurred.
“If it weren’t for them, I wouldn’t be here,” said Phillips from her hospital bed about a month after her stroke.
Thanks to an extended stay in the hospital, she has regained most of the movement throughout her body except for one hand and a portion of her mouth, which affects her speech.

6 . For today’s increasingly interconnected food supply chains, “efficient” is what it’s supposed to be: Each country specializes in what it’s best, at and puts it on the global market. Producers and processors within countries specialize, too, as a way to minimize costs. As a result, at least in theory, prices stay low, the world gets fed and everyone wins.
However, the coronavirus crisis demonstrates what is wrong with this approach. When barriers prevent food from reaching its markets, or demand suddenly drops — both of which are happening now — the system falls apart.
Specialization of the food system makes it hard to shift into different markets when disruptions arise. Belgium, a leading exporter of potatoes, lost sales not only to local restaurants but also to other countries because of lockdowns（封锁）. At least the Belgians can try to eat the potatoes at home. That strategy won't work for every crop: Ghana, the world’s top cocoa exporter, lost markets when people stalled focusing on buying essential items instead of chocolate.
The loss in export income in Africa more generally could have a huge impact if the pandemic continues, as many countries there rely heavily on imported wheat and rice. The prices of these grains have soared not only because of rising demand for these grains during the crisis, but also because a few countries — including Russia and Vietnam — imposed export restrictions out of fear that sending food abroad would lead to higher prices at home.
Concentrated markets dominated by just a handful of companies heighten food system fragility. For example, just three meatpacking plants process over 95 percent of Canada’s beef and nearly all of its beef exports. Now, those meat processing plants have had to temporarily shut down because of outbreaks of COVID-19 among workers.
Seeing the spoiled products across the world should force all of us to rethink our “efficient” food supplies. We need to rejuvenate（使恢复活力）local and regional food systems to reduce the vulnerabilities that come with being too reliant on imported and corporate-dominated foods. This doesn’t mean cutting off all trade or abolishing all packaged foods, but it does mean building diversity, and increasing opportunities for small and medium-scale enterprises to flourish in shorter, more sustainable food supply chains that are closer to home.
One place to start is for governments to shift their support from the large-scale, specialized and export-oriented food system to building infrastructure for more diverse local food systems. Around the world, small-scale and organic producers have been overwhelmed with the surge in interest from customers who want to buy directly from farmers during the crisis. But these producers often lack the infrastructure to meet that demand. As governments around the world pass stimulus packages to address the crisis, building more diverse and localized food systems should be an obvious inclusion.

7 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie—all without other people hearing the sound. That is the possibility presented by “sound beaming,” a new technology from Noveto Systems, an Israeli company.
On Friday, the company presented a desktop device that sends sound directly to a listener without the need for headphones or a special receiver. Noveto Systems gave The Associated Press (AP) a chance to test its Sound Beamer 1.0 before its debut. The AP’s Louise Dixon writes that listening to the device is like something from a science fiction movie. The sound seems so close it feels like it is inside your ears while also in front, above and behind them.
Noveto expects the device will have many uses. Office workers could listen to music or conference calls without others hearing. People could play a game, a movie or music without waking up others in the same room. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D technology that finds and follows the ear position of the listener. It sends ultrasonic waves to create sound pockets by the user’s ears. Sound can be heard in stereo or 3-D. The 3-D method creates sound on all sides of the listener The demo version of the device included nature videos of birds on a lake, bees flying and a quiet waterway. By changing a setting, the sound can follow a listener around when they move their head. It also is possible to move out sound beam’s path and hear nothing at all.
While the idea of sound beaming is not new, Noveto was the first to launch the technology. Its chief executive officer Christophe Ramstein said a smaller version of the device will be ready for release to consumers next year.

8 . When he was two years old, Ben stopped seeing out of his left eye. His mother took him to the doctor and soon discovered he had cancer in both eyes. After possible treatments failed, doctors removed both his eyes. For Ben, vision was gone forever.
But by the time he was seven years old, he had developed a technique for feeling the world around him: he clicked with his mouth and listened for the returning echoes. This method enabled Ben to determine the locations of open doorways, people, parked cars, garbage cans, and so on. He was echolocating: bouncing his sound waves off objects in the environment and catching the reflections to build a mental model of his surroundings.
Echolocation may sound like an improbable feat for a human, but thousands of blind people have perfected this skill, just like Ben did. The event has been written about since at least the 1940s, when the word ''echolocation" was first invented in a science article titled “Echolocation by Blind Men , Bats, and Radar.”
How could blindness give rise to the amazing ability to understand the surroundings with one's ears? The answer lies in a gift on the brain; huge adaptability.
Mother Nature filled our brains with flexibility to adapt to circumstances. Just as sharp teeth and fast legs are useful for survival, so is the brain's ability to reset, which allows for learning, memory, and die ability to develop new skills.
In Ben's case, his brain's flexible wiring repurposed his visual cortex for processing sound. As a result, Ben had more neurons available to deal with listening information, and this increased processing power allowed Ben to interpret soundwaves in shocking detail. Ben's super-hearing proves a more general rule: the more brain area a particular sense has, the better it performs.
1. How did Ben “see” after he had his eyes removed?| A．By using a walking stick. | B．By asking others for help. |
| C．By inventing a new system. | D．By echolocating surroundings. |
| A．Skill. | B．Task. | C．Sense. | D．Invention. |
| A．He laughs best who laughs last. | B．Actions speak louder than words. |
| C．God shuts one door but he opens another. | D．Man becomes learned by asking questions. |

9 . 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.”

10 . The spot of red was what first caught Randy Heiss's attention on December 16. He was biking on his ranch in Patagonia, Arizona, a town near the U. S. -Mexico border. Heiss walked toward it, and found on the grassland was a broken balloon with its string attached to a piece of paper.
“Dayami,” it read on one side, in a child's writing. It was a Christmas wish list, all in Spanish He suspected that a child had tried to send Santa Claus a Christmas wish list by balloon, something he used to do himself when he was a kid. And he wondered whether he could find the child who had sent this one.
It would be difficult, but based on the prevailing wind, Heiss was pretty sure where it came from—just across the border, the city of Nogales, Mexico.
Heiss then posted about his quest on Facebook, attaching photos, hoping his friends in Nogales might know the girl's family.
A few days passed with no leads. Heiss worried that time was running out before Chirstmas. On December 19. he sent a private Facebook message to Radio XENY. a radio station based in Nogales The next morning. Heiss awoke to a message from Radio XENY: They had located Dayami, an eight-year-old girl, and her family, who indeed lived in Nogales. “It just changed my entire day.” said Heiss. Having bought just about everything on Dayami's list and a few other toys, as they had learned that Dayami had a younger sister, Heiss and his wife. at the Radio XENY. met tho family.
“Their eves were wide open with wonder.” Heiss said of the two sisters' reactions. “Like. ‘Oh my gosh, this really did work!’”
Not wanting to disappoint the girls who still believed in Santa Claus, Heiss and his wife told them they were “Santa's helpers”.
“It was a beautiful and healing experience for us...” Heiss said, “Since our only son died ten years ago, being around children at Christmas time has been absent in our lives.” Heiss said. “We now have friends for life. And, for a day, that border fence with its wire melted away.”
