1 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.

What’s the problem? It’s possible that we all don’t have enough conversational ability. It’s more likely that none of us start a conversation because it’s embarrassing and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s a valuable social practice that leads to big benefits.

It is easy to consider small talk as unimportant, but we can’t forget that deep relationships wouldn’t even exist (存在) if there weren’t casual conversations. Small talk is the grease (润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. “Almost every great love story and each big business deal begins with small talk,” he explains. “The secret to successful small talk is learning how to connect with others, not just communicate with them.”

In a 2014 study, Elizabeth Dunn, professor of psychology at UBC, invited people to a coffee shop. One group was asked to interact with its waiter, the other, to speak only when necessary. The results showed that those who chatted with their server reported obviously higher positive feelings and a better coffee shop experience. “It’s not that talking to the waiter is better than talking to your husband,” says Dunn. “But interactions with peripheral (边缘的) members of our social network is important for our happiness and health.”

Dunn believes that people who reach out to strangers feel a greater sense of belonging, a link with others. Carducci believes developing such a sense of belonging starts with small talk. “Small talk is the basis of good manners,” he says.

2 . Location

St Helena is one of the remotest islands on Earth. The subtropical (亚热带的) British Overseas Territory sits in the middle of the South Atlantic Ocean, 1,200 miles from the west coast of Africa and 1,800 miles from the east coast of South America.

Size Population

St Helena is only 16 km long and 9 km wide and the population is 5,000. This is 1/3 the size of the Isle of Wight, and the same size as Disney World Orlando. This is also the same size as San Francisco-yet the island has just 0.5% of San Francisco’s population. With an extremely low-crime community, you can freely explore the island’s natural and built attractions in peace.

Climate

As a subtropical island, St Helena’s temperature is 15-28℃ all year round. While the four seasons are not recognized on St Helena, the “cooler months” are generally June to September and the “hotter months” are December to March. St Helena is free from extreme weather events, with even thunderstorms only occurring perhaps once a decade.

Accessibility

Until 2017, St Helena did not have an airport and was only accessible by sea. Reaching the island meant a five-day ship voyage from Cape Town, South Africa. However, since October 2017, the island’s first and only airport has enabled passengers to reach the island in just a six-hour flight.

From October 4 to October 6, the National English Speaking Competition     1     (hold) in Chengdu, Sichuan Province. A total of one million people of different ages, from kindergarten kids to young professionals, took part in this year’s event.

During the three-day event, young     2     (compete) expressed themselves by delivering speeches about     3     (vary) topics, including History as a Mirror, The Promise of Youth, and The Power of Dreams. In addition     4     showing their impressive English ability, they also shared their views on the world as a generation of being open-minded, individualistic, and socially responsible.

When     5     competition was first run in 1996, the goal was     6     (train) college students to master another language and communicate clearly with foreigners.     7    , in the past 25 years the event     8     (go) far beyond this simple goal. It now plays a role in helping document (记录) the major steps     9     the country takes in its development,     10     (encourage) young people to share China’s stories and providing a stage for those who will shape the future.

4 . Marine life (海洋生物) in Florida Keys is negatively influenced by two forces: human activity and climate change. The former involves fishing, tourism and diving while the latter causes a large increase in intense hurricanes. Fortunately, when the researchers of Florida Museum of Natural History started looking for sea urchins (海胆) on the ocean floor off the coast of Florida Keys in the summer of 2020, they uncovered their population had relatively been stable since the 1960s.

The researchers visited 27 sites along a 20-mile stretch of coast near Florida Keys looking for tracks that reflected the presence of burrowing echinoids (穴居海胆类动物).“The findings that burrowing echinoids have been highly resilient (有适应力的) against climate change and environmental pollution over the last 60 years was a huge discovery for us.” said study co-author Tobias Grun.

Grun said, “However, we know little about their current distribution, population size, and health. The reason is not the lack of interest by the scientific community but lies in that fieldwork is very expensive.” As the climate crisis progresses, it’s important to understand why some marine creatures are more resilient in bearing the impacts of a worsening environment than others. Grun said, “Evolution may be at play. Some marine animals are very opportunistic. They can tolerate a wide range of abiotic factors like pH, temperature, and salinity, to name a few.”

Grun added, “At this point, our data show that burrowing echinoids are more resilient than many other marine species and are doing comparatively well. That does not mean that we can push our luck and keep going the way we are right now. Our study provides some hope that these creatures are resilient, but much more work is needed to translate our findings into a larger scale. The reasons for their resilience are also widely unknown.”

6 . As people become more aware of the importance of eco-friendly power sources, we have devoted much time to inventing creative devices. A newly developed paper battery promises to make a big difference to single-use electronics.

The battery is crafted from sustainable materials, which not only strengthens its eco-friendliness but also makes it cost-effective to produce. This combination of biodegradability (可生物降解) and affordability makes it attractive for a wide range of applications. Another standout feature of this paper battery is its flexibility in terms of shape and size. Unlike traditional batteries that are available in fixed sizes, this paper battery can be tailored to meet diverse requirements.

In reality, the paper battery is enough to power an LCD alarm clock. “While it won’t be charging up your computer anytime soon, there’s lots of potential for low-powered sensors. We present a printed paper battery developed to power single-use disposable electronics and to reduce their environmental impact to the lowest level,” write the researchers in their published paper.

The battery is based on a metal-air electrochemical cell. Made from sodium chloride salt-diffused (氯化钠盐扩散的) paper, it can measure as little as one square centimeter, and is based on printed inks. All that’s needed, then, is a small amount of water, as little as two drops. This dissolves the salts within the paper, and then activates the battery as they travel. The battery starts producing power around 20 seconds after water is added, according to the experiments carried out by the team.

Although the performance decreases over time as the paper dries out, it can be topped up to some extent with more water. The researchers say they want to improve the efficiency of the battery in the future, and get it working for longer. “With a rising awareness of the e-waste problem and the emergence of single-use electronics for applications, there is a growing need for low environmental impact batteries,” write the researchers.

8 . Over the last century, engineers all over the world have spared no effort to achieve the unachievable in bridge design.

Danyang-Kunshan Grand Bridge

No bridge is as long as the Danyang-Kunshan Grand Bridge in the world. The 164.8-kilometre-long bridge built in 2011 in China serves as part of the Beijing-Shanghai High-Speed Railway. The trip from Ningbo to Jiaxing that previously took 4.5 hours has been reduced to two, thanks to this bridge.

Rio-Niterói Bridge

Completed in 1974, the Rio-Niterói Bridge in Brazil is the second-longest bridge in all of Latin America connecting the cities of Rio and Niterói across the Guanabara Bay. The Rio-Niterói Bridge is technically known as a “box-girder (箱形梁)” bridge, made of special concrete. It receives an astonishing 140,000 (or more) vehicles per day.

Hartland Covered Bridge

The Hartland Covered Bridge is the world’s longest covered bridge. The 1,282-foot-long bridge was opened in 1901 and has been on Canada’s list of National Historic Sites since 1980. Although it was originally built without a roof, the bridge was capped with wooden materials during the repairs in 1921.

Jiaozhou Bay Bridge

The newly-built Jiaozhou Bay Bridge in China was named “world’s longest bridge over water” by Guinness Book of World Records in 2011, a title previously held by the Lake Pontchartrain Causeway. The dispute was settled when the title of “longest continuous bridge over water” was given to the causeway, with the Jiaozhou Bay Bridge receiving the title of “longest bridge over water”.

10 . At first, Michael Surrell didn’t see the black smoke or flames shooting from the windows of his neighbor’s home. He had just parked around the corner from his own house when he got a call from his daughter: “The house next door is on fire!” He went to look. That’s when he saw an old woman crying outside.

“The baby’s in there!” she cried. Though the fire department had been called, Surrell, then 64, ran inside without hesitation (犹豫). Entering the burning house was like “running into a bucket of black paint,” Surrell says. The thick smoke burned his eyes and made it impossible to breathe. The conditions would have been dangerous for anyone, but for Surrell, who had lung disease, they were life—threatening (威胁生命的).

After a few minutes in the smoke—filled house, he retreated (后退) outside to catch his breath. “Where is Tiara?” he asked desperately.

“The second floor,” the old woman shouted back.

Taking a deep breath, Surrell went in a second time. Because the house had a similar layout to his, he found the stairs and made it to the second floor.

“Baby girl, where are you?”

His throat and lungs burned as if he’d breathed fire instead of the smoke in the air. He couldn’t open his eyes. All he could hear was the crackling (破裂声) of burning wood. Then a soft sound came out. Still unable to see, Surrell fell to his knees on the hot wood floor and climbed toward the sound, feeling around for any sign of the girl.

Finally, he touched something. A shoe, then an ankle. He pulled the baby toward him. Her body was weak and she wasn’t breathing. He carried her into his arms and ran blindly into the blackness. The next thing he knew, he was at the front door, then outside.
