1 . Joao Carlos Martins is a famous pianist and conductor. However, his career has been ________ and his life has taken him in many different ________.

As a teenager Martins began to perform in concerts. But in his late twenties, he had to ________ after badly breaking his arm. It was really a terrible time. He couldn’t look at a piano or ________ listen to music. ________, he decided to become the manager of a boxer, who won the world championship later. This ________ Martins to take up the piano and practise much harder. Six years later, he gave his first concert at the Carnegie Hall, which was the most ________ moment of his life. He performed in concerts for years before he had to quit because of the unbearable ________ in his hands caused by too much ________.

Martins, in his forties, became a politician. However, he couldn’t stand this ________, so once again, he went back to the piano. All was going well until something unexpected ________ while leaving a concert. He ________ a serious brain injury and lost all the movement in his right hand. Again, with great ________ he played just with his left hand. Years later he lost the use of the left hand and ________ himself a conductor. Now, in his late seventies, Martins is still taking ________ to work and has conducted over a thousand concerts.

3 . This 3-mile stretch of sand and tide pools beneath a castle of 80-foot cliffs is a California tourism poster if there ever was one. Nothing disturbs the perfect, sunny view, except — once you’re aware of them — microplastic particles (颗粒). But you have to look close-on-your-hands-and-knees close-to see one. And once you do, you see another and another — so many that you may not think of this, or any beach, the same way again. These tiny preproduction plastic balls that manufacturers (生产商) melt down to form everything have been escaping factories, container ships, trains, trucks — and public notice — for decades.

The 2- to 3-millimeter, multicolored balls are a subset (子集) of microplastic-plastic particles less than 5 millimeters in size. Microplastic particles accumulate where water takes them, and they’ve been found on shorelines of every continent.

Dr McReynolds is an environmental scientist who’s now joined a global movement studying their trail into the environment. Establishing a baseline count of the presence of microplastic particles — and, more broadly, any microplastics — is the focus of Dr McReynolds’ scientific study here. Charting the count, noting tide, current, and weather conditions will show if amounts are increasing, and perhaps at what rate and why. That knowledge, he says, can inform solutions to plastic pollution such as regulation of their use.

“What are you doing? Picking up trash?” asks a steady stream of beach walkers whenever Dr McReynolds’ crew walks onto the beach and sets up equipment. These are teachable moments for Dr McReynolds.

One recent morning he told some beach walkers how microplastic particles are believed to absorb toxic chemicals, and — because they resemble fish eggs — are eaten by fish and birds and enter the food chain. Almost right on time, a seagull hopped up to a plastic-coated photo of microplastic particles and hungrily pecked (啄食) at it.

Will his work help save the world? Dr McReynolds waves a finger at that idea, “I won’t ever use that word — I won’t save the world from this pollution problem. Preserve it, yes. We want to take care of it.”

4 . In today’s digital era, social media users are increasingly coming across fake news online. This leads to the pressing issue: What causes people to fall for misinformation on the Internet?

According to researchers at the Penn State College of Information Sciences and Technology,   users can easily fall into an echo chamber (回声室)—a sort of virtual space where users consume only one-sided news, eventually distrusting any opposing views. “We all tend to agree with the group opinion. Hence, people naturally get together with others who hold the same opinion,” said Dongwon Lee, one of the researchers. “But if you’re not cautious, there is a high risk of falling into an echo chamber.”

To prevent this phenomenon, the researchers have crafted a novel tool, a game named ChamberBreaker, to help players resist echo chambers and reduce the rate of fake news spread. The fundamental approach employed by ChamberBreaker centers around a decision-making procedure that mirrors the creation of echo chambers. In ChamberBreaker, a player is tasked with trying to have community members fall into an echo chamber. To begin, the player is randomly assigned a situation that focuses on a health, political or environmental issue, and is presented with six pieces of news on that topic. Then, the player selects news that could cause the other members to fall into an echo chamber while at the same time maintaining their trust. If successful, the community members will fall into an echo chamber and the player will witness the resulting negative effects on the community.

After developing ChamberBreaker, researchers tested it with over 800 subjects to see if it raised awareness of echo chambers and changed news consumption behaviors. The researchers found that those who played ChamberBreaker were significantly more likely to state their intention to observe online information from more diverse perspectives and showed an increased awareness of the echo chamber phenomenon.

Ultimately, the researchers hope that their methodology can excite a greater interest in the scientific and scholarly study related to information consumption. The application of tools like ChamberBreaker, which focuses on fostering analytical reasoning, may lead us towards a more informed online community.

5 . No poverty, zero hunger, quality education, these are some of the 17 Sustainable Development Goals(SDGs)the United Nations(UN)established in 2015. In May 2019, the UN launched the SDG Book Club; each month, it posts on the club website a selection of books that illustrate a particular SDG to help young people interact with these goals.

Batesville Intermediate School launched the Junior Ambassadors (大使) program in August 2019, using the SDG Book Club as a springboard to introduce students to a more global view on world issues. Twenty-four 4^th and 5^th graders met for 30 minutes four days a week to read, discuss, research, and conduct the sharing of knowledge and solutions to these issues. Research activities, special projects, and guest speakers are additional opportunities for junior ambassadors to build knowledge. What began as a desire to help small-town children expand their views grew into a broader program that affected the school, community, and beyond.

The UN’s recommendation of Serafina’s Promise by Ann E. Burg was perfect for the junior ambassadors to begin their study of the first SDG: no poverty. The book is set in Haiti, so members of local Haitian groups were invited to speak to the program participants. Then, the junior ambassadors used their newfound knowledge to create multimedia lessons, sharing them with the other 480 students.

The study of the second SDG — zero hunger — gave junior ambassadors an opportunity to organize and carry out a read- a-thon (a reading marathon) to raise funds for the Grain of Rice Project’s school initiative in Kenya. The nonprofit’s co-founder, Amy Ahiga spoke to and inspired the students with her passion for helping others.

Junior ambassadors use what they learn to engage with their community and the world, earning the school the American Library Association’s 2020 Sara Jaffarian School Library Program Award for Excellence in Humanities Programming. They can look back with pride, knowing they made a difference. With increased confidence and skills, these children will know that they can and will continue to save the world — one goal at a time.

6 . To much of the world, bullfighting has always been distinctly Iberian. But these days, parts of France are laying claim to this tradition. From the Cte Basque to the arenas of Arles and Beziers, it has spread to towns where bullfighting has long been banned, and been embraced with such enthusiasm you’d think the sport had been born there.

The rising passion for blood and sand has been resisted by animal-rights activists. Last month someone set off a bomb near the bullring in Carcassonne. Yet France’s enthusiasts fiercely defend their right to these moral rituals. Bullfighting, they insist, is part of the heritage, an expression of a shared regional culture that should be protected.

The rest of the Continent should take note. The paradox (自相矛盾) of an ever-more-united Europe is that as borders between member states become less important, so do the nations themselves-and regional identities are valued. It’s easy to forget that most European nation-states were created as we know them only during the 19th century, after a long series of bloody conflicts. “If the chances of war had been a little different, all the regions sharing bullfight might have been together,” argues Jean Michel Mariou, a huge fan of bullfighting. On both sides of the Pyrenees there are Basques, there are Catalans, there are common cultures, he says. “Bullfighting is only one expression of it.”

Bullfighting isn’t the only cultural tradition that has begun to go beyond borders, of course. To name but one other: the Celtic revival, built largely around musical groups along the coast of Ireland, Scotland and Cornwall, Brittany and Normandy. But while bagpipes (风笛) may stir the blood, they don’t spill it. And the violence of bullfighting horrifies many people who don’t feel they share in its culture.

“The concept of lasting local tradition doesn’t mean anything anymore,” says Josyane Wuerelle, coordinator of the Federation de Liasions Anti-Corrida in Agde. Bullfighting is about attracting tourists, not honoring local history, she argues. Robert Marge doesn’t see it that way, of course. He recently declined an invitation to organize a bullfighting in Paris’s enormous Stade de France. “We didn’t want to sell our souls by bringing bullfight to a region where it doesn’t exist,” he explains. But he has also got the sense to know that some traditions don’t travel well.

8 . Residents at Parkfield House Nursing Home celebrated the end of a £10,000 project with a showcase of their work with friends and family.

For the past year the group, known as the Parkfield Peckers, have worked closely with artists, Glebe Primary School and creative ageing charity Equal Arts as they delved into the history of the area and those who’ve lived at the 19th Century home.

Hannah Wood from charity Equal Arts said: “The exhibition at Uxbridge Civic Centre was just the icing on the cake! Going into the project, there was so much enthusiasm from the group to explore the heritage of the home, so many have their roots in the area and we were keen to capture and share their knowledge in creative ways.”

There’s been a mixture of creativity with illustration, photography, portraiture, music, story-telling and collage as the group took part in weekly artist-led workshops and linked up with schoolchildren to share ideas.

Glendeen Quow, manager of the Canford Healthcare-run home, is in no doubt about the project’s benefit to residents, staff and the home. She said: “It’s been a busy year and we have all loved every minute of it. It’s been a privilege to learn about our fascinating heritage and a joy to see our residents grow in confidence each week as they were introduced to the different workshops and artists. We have enjoyed strengthening our relationships with the local community, especially with the staff and children at Glebe Primary School.”

Clare Sheldon, who provides Pastoral Support at Glebe Primary School, said: “The children have been proud to be a part of this project and connect with the Parkfield residents. It’s been great for them to have experience in talking to and sharing with older people, it gives them a stronger sense of understanding and compassion. This project has been a great way of exploring their own emotions and identity and we look forward to continuing our friendship with Parkfield.”

9 . I grew up in Michigan and have loved boats since I was young. I’d go out on my dad’s fishing boat, and every birthday I’d get a miniature boat with a viewing window. In Michigan, we’re _________ by lakes and I soon discovered that I loved diving and _________ skipped school days for the beach.

Three years ago, I _________ put forward an idea of running glass-bottom boat tours to an investor. It started in 2018. At present, My sons _________, manning the deck(甲板)and phones. We head out on the Cheboygan river and Lake Huron. We sail past lots of places of_________, with a historian on board explaining the history. We often scan the river to see what we can find.

One weekend this year, I met a _________ client. I thought I should find something to show him and managed to find a giant shell. Then I saw a green bottle. I swam to my boat, took a photo and then opened the bottle. It was full of water and had a paper inside. I _________ the paper and saw the date —November 1926. We were all amazed. The note_________: “Return this paper to George Morrow.” I was so excited to have found it.

We made sure to keep the paper safe. Before leaving the harbor, I posted a picture on my Facebook page and didn’t expect what followed.

The next morning, my phone _________ with messages. While I was driving home, I got a phone call from Michele Primeau. She told me she was George Morrow’s daughter. I didn’t believe her __________. She said her dad would float notes in bottles when he went on vacation or __________ them in walls when redecorating. She __________ he had posted this one on his 18th birthday.

In autumn, Michele came to visit. She brought some of his writing and the handwriting matched. She __________ I keep the message and the bottle.

It now sits in a display case in my shop. That Facebook post now has 87,000 __________. In a hard year, the discovery has brought purejoy.__________a Scuba diver(水肺潜水员), this feels like a lifetime achievement.

10 . Living in a city is a well-known risk factor for developing a mental disorder, while living close to nature is largely beneficial for mental health and the brain. A central brain region, the amygdala (大脑杏仁核) involved in stress processing, has been shown to be less activated during stress in people living in rural areas, compared to those who live in cities, hinting at the potential benefits of nature. “But so far the hen-and-egg problem could not be resolved, namely whether nature actually caused the effects in the brain or whether the particular individuals chose to live in rural or urban regions,” says Sonja Sudimac.

To achieve causal evidence, the researchers from the group examined brain activity in regions involved in stress processing in 63 healthy volunteers before and after a one-hour walk in Grunewald forest or a shopping street with traffic in Berlin. The results revealed that activity in the amygdala decreased after the walk in nature, suggesting that nature elicits beneficial effects on brain regions related to stress.

“The results support the previously assumed positive relationship between nature and brain health, but this is the first study to prove the causal link. Interestingly, the brain activity after the urban walk in these regions remained stable and showed no increases, which argues against a commonly held view that urban exposure causes additional stress,” explains Simone Kühn, head of the group.

The authors show that nature has a positive impact on brain regions involved in stress processing and that it can already be observed after a one-hour walk. This contributes to the understanding of how our physical living environment affects brain and mental health. Even a short exposure to nature decreases amygdala activity, suggesting that a walk in nature could serve as a preventive measure against developing mental health problems and reducing the potentially disadvantageous impact of the city on the brain.

In order to investigate beneficial effects of nature in different populations and age groups, the researchers are currently working on a study examining how a one-hour walk in natural versus urban environments impacts stress in mothers and their babies.
