1 . When Param Jaggi was five years old, he had a passion to take things apart to see what was inside. He started with toys and even broke a computer, which made his parents not too pleased. As he got older, he shifted from breaking things to building things, which greatly comforted his parents. In middle school. he started working on projects in his kitchen laboratory, and his first project was making biofuels.

Although Jaggi’s parents initially thought his experiments were just. a boyhood fancy, he remained determined to make a difference to the environment. Eventually, his parents came around and started supporting his dreams. Jaggi’s interest continued as he grew up, but he focused more on solving real problems, especially those related to the environment.

At 17, Jaggi went beyond his school projects and. co-founded Ecoviate, a company that uses technology to solve everyday energy and environmental problems. He planned to transform people’s idea that going green is expensive, by making available a series of affordable products that are easy to use. Through Ecoviate, he designed products that could contribute to a greener future. One of his notable inventions was the “CO2ube”, a device that could be attached to vehicle tailpipes to reduce carbon emissions, and it’s available to many people at low prices. He also created a smartwatch that changed body heat into energy, which can be used to power up the watch as well as mobile phones.

Young Jaggi, now a third-grade college student studying engineering and economics, has become a famous eco-innovator and his company is developing promisingly. However, Jaggi’s vision to save the environment goes beyond creating products. He plans to launch an online platform through Ecoviate, which will encourage young students interested in science and technology to get actively involved in innovation and invention. Students can submit a science project online, and talk about the help that they need to make the project a reality.

2 . Adrienne Tully, an amateur photographer, went to the coast of a beach in Belmar, New Jersey. She planned to take photos of the ______ against the sea. Instead, she was able to ______ a frightening but happy journey. It all started last Sunday morning when she noticed a crowd ______ on the beach. Naturally, she joined them in the ______ of learning what was going on.

For a minute, Adrienne was ______ about what everyone was looking at. From how far away they were, it almost seemed like a bird. Looking closer, ______ , it was clearly a deer who was ______ on a raised rock in the middle of the ocean. The deer made a couple of ______ to swim back to the shore but the turbulent (汹涌的) water ______ all its efforts. Then someone who came out of nowhere ______ rode his surfboard to the deer. After a short magic while, the ______ managed to guide the deer out. Upon ______ ashore, the deer just ran north on the beach. Those watching nearby were no doubt ______ at the way this nameless young man ______ to help. But he somehow disappeared too, leaving people to hope he knows that he is greatly ______ for what he did.

6 . An Art Class

When Kelly was twelve, she started taking classes at Miss Grace’s School for Art. She didn’t like it at first: the “novice artists”—the kids who hadn’t really done art before-worked mostly with clay, and Kelly was a terrible sculptor.

It wasn’t until her third year that Kelly found something she was really good at-charcoal drawing (素描). She loved watching the lines spread unevenly across the page as she moved the bits of charcoal back and forth over the paper.

One day, Sophia, the best artist in her class, sat down and set up her easel (画架) next to Kelly. Kelly felt a sinking feeling in her stomach. She’d actually found an art form that she enjoyed and was good at-and now Sophia was going to outshine her again? Kelly fought back tears when Miss Grace entered the room.

“Hello class, Miss Grace said.” We’ll continue to work on the project today. What masterpiece would Sophia have come up with?

Kelly looked at Sophia’s easel and she couldn’t believe it-it was a mess! For a brief moment, Kelly couldn’t actually believe her drawing was better than Sophia’s.

But then she looked at Sophia, who was watching Kelly with an anxious expression. “I…. I couldn’t decide what to do,” Sophia said. “And you’re so good. Sometimes I feel like my stuff is just so bad in comparison.”

Kelly looked to see if Sophia was joking, but she seemed completely serious. Now Kelly was shocked. “I’m not talented ... Miss Grace seldom praises me. You’re the best one in our class!”

Sophia raised her eyebrows. “I might be a really good copier of the stuff, but I have no idea what to do when it comes to making up my own images. You are so great at making new things out of the old stuff. I’ve loved your works.”

“I’ve loved yours, too,” Kelly said.

“Well, definitely not this one,” Sophia said.

Kelly smiled. “Maybe not right now. But if you move these lines up...” she said, pointing her finger on Sophia’s paper.

Sophia was quiet for a moment. “That’s a great idea!” she said finally.

Kelly smiled and turned back to her drawing, looking every so often at Sophia’s work to see that she was taking her advice, down to the last line.

7 . I’m sitting impatiently in our dusty car looking out. My travel buddy, Lucas, having taken in enough of the ________ , has gone to speak with someone from one of the nearby tourist souvenir huts. After ages, he walks towards me, ________some sausages, hot water, a new cowboy hat, and a big grin on his face. “We’re giving a man a ________ ,” he tells me.

The idea seems ________but somehow safe, given that there are two of us and Lucas is a ________   to the country. How exciting to create an opportunity to meet people that you wouldn’t have met ________ .

Now,as I look at Lucas’ new friend, I see a different kettle of fish. Michael is big. I mean really BIG. I watch in the side mirror as Michael ________towards the car. In his right boot is a big knife, pushed far enough in that only the handle and the base of the blade poke out. A knife!

I would normally be alert to this ________ stranger now sitting in the back of my vehicle. However, with Lucas now eagerly ________ with him in a language I barely understand, I’m trying to let myself ________ . Then Lucas loosely translates the conversation they’re having as Michael proudly ________ his knife, explaining that he uses it for everything: opening bottles, picking his teeth, castrating his cows.

Gradually, my___ towards our new stranger grows as he persistently tries to communicate with me, ________the mood of the car. Twenty minutes down winding mountain roads and we reach Michael’s house, where we are invited to have a meal with his ________ . Later that day, we leave the house without taking any contact details from Michael. There is an unspoken understanding that this________friendship is enough.

8 . Babies as young as 4 months old who are born into a bilingual (双语的) environment show distinct and potentially advantageous brain patterns for speech processing. Our early-life experiences can have lifelong effects on our behavior. The brain is most sensitive to its environment during the first year of life, which is thought to be a critical period for language development.

Previous studies have looked into the brain mechanisms that underlie (构成……的基础) speech processing in babies who hear just one language. To better understand this in bilingual-exposed infants, Borja Blanco at the University of Cambridge and his colleagues compared how 31 babies who only heard Spanish and 26 babies who heard Spanish and Basque, all aged 4 months, responded to Spanish recordings of The Little Prince by Antoine de Saint-Exupery.

The team used an imaging technique called functional near-infrared spectroscopy (fNIRS) to measure changes in brain activities. In the Spanish-only babies, the recordings caused activation in areas which play a role in speech processing. In the bilingual-exposed babies, the recordings similarly evoked these responses, but they were larger and wider. These infants also had activation in equivalent areas of their brains’ right hemispheres ( 脑半球 ). When the recordings were then played backwards as a control arm of the experiment, the infants exposed to just Spanish had larger responses to the backwards speech, while those to Spanish and Basque had similar brain patterns as before. This may be because the bilingual infants take longer to register their primary language, in this case Spanish, as hearing both this and Basque reduces their overall exposure to either language.

If this is the case, it could help them be sensitive to linguistic differences and enable them to learn to distinguish between languages at a younger age. The researchers note that a bilingual environment stimulates changes in the brain mechanisms underlying speech processing in young infants, adding weight to the idea that the neural basis of learning two or more languages is established very early in life.

9 . Three years ago, Juan Carlos Sesma had a realization. Global warming and climate change seemed to be a mounting problem, with scientific records indicating rising temperatures and sea levels across the world. At the same time forest fires, logging, and aggressive human expansion meant the supply of trees which helped to regulate and remove greenhouse gases from our atmosphere was dwindling .

He decided the best way to tackle a problem this large was to combine two of the most powerful forces emerging in technology: big data and robotics. Sesma founded a new company called CO2 Revolution, whose plan was to use drones(无人机) to better understand where new trees should be planted and to automate the process of planting so that much larger areas of forest could be repopulated. The company designed a special smart seed that helped to deliver just the right amount of protection and nutrition to the young saplings. The overall goal was to considerably lower the time and cost of large-scale re-forestation.

CO2 Revolution isn’t alone. In the UK, a startup called Biocarbon Engineering ran a trial earlier this year where it used drones to help replant Mangrove trees in Myanmar. It has also deployed(部署) its technology in Australia, South Africa, and Morocco. “In a lot of places, people will either have a map taken by aeroplane, or just use Google Earth satellite imagery.

They’ll draw things out freehand and manually plant, either by hand or tractor,” said CEO Susan Graham in a recent interview.

The challenge for all these startups is to find ways to create a profitable, or at least sustainable, business model. For Sesma and the team at CO2 Revolution, recent regulatory action has highlighted one potential pathway. “We offer a solution that allows clients to carry out massive plantings, increasing forest mass and thus compensating for their carbon footprint.” Amid growing calls for carbon sequestration, this kind of effort might prove not just noble, but financially sensible for large corporations.

10 . US Army veteran (退伍老兵) Mazyck remembers when doctors told her she would never walk again. She’d been paralyzed from the waist down after a serious accident while parachuting in 2003.The doctors never said anything about floating, though. In 2021,she got to do just that.

Mazyck was one of 12 participants in a Zero G flight, organized by the group AstroAccess. This type of flight recreates the weightlessness that astronauts experience without going all the way to space. Flying over the Pacific Ocean off Southern California, the modified 747 jet airplane made 15 steep dives and climbs, allowing the flyers multiple periods of weightlessness.

The experience left Mazyck feeling joyful. “The flight was something that I would have never in my wildest dreams thought I would’ve experienced,” she says, “especially the floating, the weightlessness.”

Traditionally, strict physical requirements have prevented disabled people from becoming astronauts. AstroAccess is working to make space accessible to all. “Space removes the barriers between people; now is the time to remove the barriers to space itself,” says Mazyck, “It is sending a message to people who have historically been excluded from STEM that not only is there room for you in space, there is a need for you.”

During the flight, she says, the participants did experiments and made observations. They took note of things that people without certain disabilities might not realize are issues. For example, people who couldn’t grip with their legs needed another way to hold themselves still while weightless. The group also experimented with signaling lights for the deaf and with ways of using braille (盲文) for the blind.

These types of issues are easy enough to address. Now is the time to make space accessible — before space tourism or space settlements become commonplace. “I am so proud and elated about what’s happening here,” Mazyck adds. “We are paving the way for the future.”
