1 . China Science and Technology Museum has teamed up with space experts to spark students’ interest in the final frontier by opening an experience center to share knowledge about the country’s Tiangong space station.
The museum says it hopes to help young people understand how the space station works and foster greater interest in China’s manned space program. The experience center’s first event on Monday attracted space enthusiasts of all ages. To satisfy the students’ curiosity, the museum even had a replica (复制品) of the Tiangong space station’s core module on exhibit.
“I learned that the core module of Tiangong actually has three parts. I thought it was just one,” said Lang Xujun, an eight-year-old student from Yuxin School in Beijing.

2 . Regardless of how famous they are, and despite the star treatment they receive, many celebrities make it a point to give back to charities. Some have even set up their own private foundations. Their widely publicised visits to troubled areas of the world help to raise awareness of issues such as famine and poverty. According to Jane Cooper of Unicef UK, celebrities have a unique ability to reach huge numbers of people, many of whom might not otherwise be engaged in charitable causes. She pointed out that famous faces had played a significant role in raising funds in recent years, and their energies had produced tangible results, such as enabling millions of children in poorer countries to attend school.
But in spite of these successes there is evidence to suggest that celebrity endorsement (代言) may be overrated. In a survey of members of the public to find out if celebrity involvement would encourage people to donate, researchers found that the impact was not as great as previously thought. When shown a list of well-known organisations and famous people who represent them, over half of respondents were unable to match the celebrity with the cause. What’s more, three quarters claimed that they didn’t respond to celebrity endorsement in any way. The survey also showed that a few names did stand out as being associated with particular charities. But the presence of a celebrity in a campaign, was not a significant factor when it came to a decision to donate time or money. Instead, the majority of people contribute because of personal connections in their lives and families which make a charity important to them.
In another study aimed at young people, most participants cited a compelling (无法抗拒的) mission as their main motivation to give. The second most important incentive was if a friend or peer recommended supporting a particular cause. Only two percent of respondents said they were motivated by celebrity endorsement. This seems to contradict the general assumption that teenagers are particularly influenced by famous people. One possible explanation is that there is a general fatigue (疲倦) with celebrity culture. There is also a suspicion that the stars are the one who benefit most when they offer to do charity work. Some critics have accused that celebrities might actually take attention away from issues by attracting more attention than the causes they represent.
So taking all these issues into account, is it time for charities to rethink their campaign strategies and look for alternative ways to reach new audiences? Whichever point of view you favour, there seems to be opportunities for more research into how charity campaigns might develop relationships with celebrities to maximise their potential. This in turn will open up more engagement, and better targeted campaigns-which can only benefit those who really matter — the people and animals that are in need of assistance.

3 . In many cultures, it is considered unlucky to spill salt. Fortunately, many cultures also have a solution to the problem, which usually involves throwing a pinch of salt over your shoulder. It may seem confusing to modern humans, but knowing that salt was once incredibly valuable can change this perspective.
For thousands of years, salt was an extremely rare commodity. It was difficult to obtain so that the price was very high. Many trading routes were set up to carry salt, people were paid in salt, and salt was sometimes worth more than its weight in gold. Therefore, spilling salt was considered wasteful.
Because of its high value, salt was also associated with friendship and good fortune. Offerings of salt were included in many religious ceremonies, and people might bring salt to a new home for good luck. These associations would have suggested that it would be bad luck to spill salt, since it would seem to violate salt’s fortunate properties.
Salt is also an excellent preservative. It prevents food from going bad. As such, it came to be linked with health and longevity. In some cultures, spilling salt was thought to reduce one's well-being. In Britain, for example, each spilled grain was said to represent a tear, while in Germany spilled salt awakened the devil, bringing misfortune.
The fear of spilling salt was also adopted into the Christian faith. It is said that Judas spilled salt at the Last Supper, and since he later turned out to be the betrayer of Christ, spilled salt is considered unlucky by many Christians.
Should you be unfortunate enough to spill salt, you might throw a pinch over your left shoulder to blind the Devil.

4 . Sora observed in amazement as Weilun picked up two large metal cans. She followed Weilun with a pail (桶) of clothes, watching him carry the two cans effortlessly. They were large and were covering Weilun’s small frame.
Sora’s father had sent her to the village to learn about rural life. Sora had never once done any household chores back home. She did not understand why her father would always chant “Where is your willingness to learn?” whenever she asked him if she could stay home for the holidays. Her father had given her a checklist on the life skills that she needed to learn, one of which was to wash clothes. She recalled washing a table cloth after an art lesson in school. That was a piece of cake, she thought. So Sora refused Weilun’s offer to help. Weilun then went to fill the large cans with water at the far end of the river.
Suddenly, a big bird dived from the sky when Sora placed the last piece of clothing back in the pail. Sora released her grasp of the pail in shock. Then she was relaxed to find it was aiming for a worm near her. But the clothes were drifting in the river. Weilun immediately came to help and Sora shifted the blame to the bird.
He pointed at the detergent foam (洗涤剂泡沫) on the surface of the river. “Don’t tell me you rinsed (漂洗) the detergent from the clothes in the river. Don’t you know that it may kill the river creatures? You caused the problem, not the bird!” Sora looked down in shame. “You think that you know everything, but you actually don’t.”
Sora closed her eyes to let Weilun’s words sink in for a moment. She finally understood the meaning behind her father’s chants. She walked towards Weilun and whispered, “Could you teach me all the life skills that my father had planned for me to learn?”

5 . Independent living at home is the ideal for every aging person. But a fall or other health-threatening incidents can change everything rapidly.
The wearable “panic buttons” introduced in the late 1980s were a great advance. But they only work if people actually wear them and can reach the button in an emergency. Today there are passive wearables that automatically detect falls, and camera-based systems to monitor elder safety.
Coming from a 40-year career in the semiconductor and wireless communication field, Rafi Zack decided to find a better alternative. “People aren’t devoted to wearing small devices 24/7, and camera-based systems are an invasion（侵犯）of privacy,” he points out, “The most challenging aspect is a fall. How fast we can detect a fall matters because the medical situation worsens quickly. Sometimes people stay on the floor for a long time. We have to find out how to solve that problem.”
Zack is a co-founder, CEO and vice president of R&D at EchoCare Technologies which has developed ECHO (Elderly Care Home Observer), a cloud-connected monitor based on radar technology and machine learning.
Because radar sees through walls, one ECHO unit fixed on the ceiling or wall can monitor one person (or two persons, in a future version) in a standard-sized apartment in a senior living facility. The device detects falls, breathing difficulties, drowning in a bathtub and other dangerous events. It gives out warnings to potential health worsening conditions by continuously monitoring and analyzing the person’s location, posture（姿势）, motion and breath. EchoCare tested the device in the United States, Japan, Australia and Israel. ECHO was certified（认证）in 2019 in Japan with the most aging population in the world.
“Bathrooms were the main testing area where about 17,000 deadly accidents happen annually.” said SMK Director and Executive Vice President Tetsuo Hara. “Bathroom makers, home security service providers and nursing homes are highly interested in EchoCare’s solution.” Zack noted, “As more and more elder people live alone as a result of social distancing, there is an increased need to monitor them without the burden of wearables or privacy-invading cameras.”

6 . A young woman was walking in Santa Ana, California, when she came upon an elderly street vendor (小贩) selling tamales (玉米粉蒸肉). Seeing how tired he looked in his wheelchair, she decided to give him a few bucks and a sandwich—and she also gave him a sympathetic ear to listen to his story.
When Kenia Barragan first saw Jose Villa Ochoa, she thought of her own parents. “I felt for him,” she told KTTV News, “My parents are both older, and I would hate to see my dad out selling tamales for somebody and barely making ends meet.”
Known as “Don Joel”, he explained that although he wanted a job, no company would hire him because of his age. In order to keep himself out of debt, he started to sell tamales cooked by a local woman. At the end of each hard day, she would give him a cut of the earnings. This allowed him to buy food, but was not enough for him to afford his medical treatment or a phone.
The 28-year-old woman was happy to listen to Don Joel’s story, but she wanted to do more. She made an appeal to her followers on Instagram for some assistance. Within a week, friends and strangers flooded her with more than $84 000 in donations.
In addition to the money raised for Don Joel’s retirement, Kenia purchased him a new wheelchair and a shiny new pair of shoes. Even though he’s 94, he says he feels like he’s 40 now, because the kindness has made him feel so alive. He describes the generosity as “life-changing”.
Kenia feels exactly the same way. She says she’s always looking for a purpose that helps people and that she’s been living in line with those values in her current job, working with people who have disabilities to get them transportation. Her goal in life is to establish a homeless shelter.

7 . The first wave of a new class of anti-aging drugs have begun human testing. These drugs won't let you live longer but aim to treat specific illnesses by slowing a fundamental process of aging.
The drugs are called senolytics—they work by removing certain cells that accumulate as we age. Known as “senescent” cells, they can create low-level inflammation (炎症) that prevents normal systems of living cells repair and creates a poisonous environment for neighboring cells.
In June, San Francisco - based Unity Biotechnology reported initial results in patients with mild to severe osteoarthritis (关节炎) of the knee. Results from a larger clinical trial are expected in the second half of this year. The company is also developing similar drugs to treat age-related diseases of the eyes and lungs, among other conditions.
Senolytics are now in human tests, along with a number of other promising approaches targeting the biological processes that lie at the root of aging and various diseases.
A company called Alkahest injects patients with components found in young people's blood and says it hopes to stop conscious and functional decline in patients suffering from mild to moderate Alzheimer's disease. The company also has drugs for Parkinson's and dementia in human testing.
And in December, researchers at Drexel University College of Medicine even tried to see if a cream including the immune-suppressing drug could slow aging in human skin.
The tests reflect researchers' expanding efforts to learn if the many diseases associated with getting older- such as heart diseases, arthritis, cancer, and dementia- can be dealt with to delay their outbreak.
1. Why do the researchers develop the drugs?| A．To rid inflammation. | B．To lengthen people's life. |

8 . During the COVID-19 pandemic, Julia began her second year as a first grade teacher in an online classroom. One September afternoon, she received a call from and Cynthia, who was having technical difficulties with her granddaughter's tools for online learning.
Julia immediately knew something was wrong with Cynthia. The two women had spoken many times before, but Julia had never heard she sounded like this. Her words were so jumbled that Julia could barely understand her. Julia called her headmaster, Charlie, who convinced her that he would call and check on Cynthia himself.
Just like Julia, Charlie could barely understand Cynthia. He suspected she might be having a stroke (中风) — he recognized the signs from when his own father had suffered one. Charlie immediately became concerned that Cynthia's two grandchildren, ages six and eight, were probably home alone with her and scared. Charlie asked his office manager to send an ambulance to the grandmother's home.
The quick response from Julia and Charlie saved Cynthia's life. She arrived at the hospital in time to get treatment before long-term damage occurred. Thanks to an extended stay in the hospital, she has regained most of the movement throughout her body except for one hand and a region of her mouth.
“I'm proud of the people I work with, that they responded so quickly and that it did make a difference to Cynthia,” says Julia. “I am so pleased to be part of such a caring community.” But the school's crisis response is only one piece of the community's extraordinary efforts to help Cynthia and her granddaughters. Another family with young children took in the two girls.
Virtual learning has been a challenge across the country, but it's fair to say that it has helped the community grow closer. Many teachers there gave their personal phone numbers to students and families in case they needed extra help. In this case, the exchange was literally life-altering.
1. Cynthia called Julia in order to .| A．complain about the poor contents of online learning |

| C．It has provided more benefits than challenges. |
| D．It needs technical guidance to be highly effective. |
9 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.
“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”
To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.
The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.

| C．Artificial intelligence-a better choice in driving. |
| D．The strengths of artificial intelligence in transport. |
10 . After beating bone cancer, Hayley Arceneaux thinks rocketing into orbit on SpaceX’s first private flight should be no problem at all. St. Jude Children’s Research Hospital announced the 29-year-old doctor’s assistant will rocket into space later this year.
Arceneaux, a former patient at St. Jude, will become the youngest American in space, beating NASA record-holder Sally Ride by over two years. She will travel with businessman Jared Isaacman, who is using the spaceflight he bought to raise money for charity. Two other yet-to-be-chosen space flyers will join them. Arceneaux will be the first person to launch with a prosthesis an artificial device that replaces a missing or injured part of the body. When she was 10, Arceneaux had an operation at St. Jude to replace her knee and a piece of metal was put in her left leg. She still limps and has occasional leg pain.
“My battle with cancer really prepared me for space travel,” she recently told The Associated Press. “It made me tough, and then also I think it really taught me to expect the unexpected and go along for the ride.” Arceneaux wants to show her young patients and other cancer survivors that “the sky is not even the limit anymore.” “It’s going to mean so much to these kids to see a survivor in space.” she said.
Isaacman announced his space flight on February 1, promising to raise $200 million for St. Jude. As the flight’s self-appointed commander, he offered one of the four seats aboard SpaceX’s Dragon spacecraft to St. Jude. The hospital chose Arceneaux from among its many workers who had once been patients. The idea was that one of them could represent the new generation, noted Rick Shadyac, president of St. Jude’s financing organization.
Arceneaux was at home in Memphis, Tennessee, when she got a surprising call in January. She was asked if she would represent St. Jude in space. As a lifelong space fan who loves adventures, Arceneaux has traveled widely and loves roller coasters. Isaacman, who flies fighter airplanes for fun, considers her a perfect fit. The launch is planned for this fall at NASA’s Kennedy Space Center, with the spacecraft orbiting Earth for two to four days.
