On Friday, the company debuted (首发) 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 that 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. However, 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 (超声的) 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 company said.

The demo (样本) version of the device included nature videos of birds on a lake, bees flying and a quiet waterway. Most people trying the technology for the first time just say, "Wow. I really don't believe it. It sounds like a speaker, but no one else can hear it... it's supporting you and you' re in the middle of everything. It's happening around you."

By changing a setting, the sound can follow a listener around when they move their head. It is also possible to move out of the 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 would be put on the market next year.

Roshawn Little is going into her junior year at Eastern, and has been working in this garden for three years now. During the summer, Little gets paid to work Tuesday through Saturday from 9 a. m. until 2 p. m. with City Blossoms, a nonprofit that brings community gardens to schools in urban areas. She believes that working in the garden has taught her to try all sorts of new things, like eating different kinds of vegetables more often. And she's taken those healthy behaviours home with her and her eating habits have encouraged her family to buy more fruits and vegetables.

City Blossoms is one of many groups across the country teaming up with local communities to build school gardens, like the one at Eastern. It works with schools to create learning gardens and trains teachers on how to use them to get students engaged (使参与) and improve academic performance. These gardens are really outdoor classrooms. For example, the gardens can be used for math lessons, like calculating the area of a plant bed or learning the science of how plants grow.

For the students, the experience can be a nutritional eye-opener, which has totally changed their views on where food comes from, and what it takes to produce food. Partner schools have also seen a 12 to 15 percent increase in the number of students passing standardized tests and 94 percent of teachers reported seeing increased engagement from their students, according to an independent evaluation (评价) conducted by PEER Associates.

a practical tool to learn Chinese language and culture

Confucius said: "To educate somebody, you should start with poetry, and finish with music".

I was doing homework with my friend Ollie at his home when he randomly started scribbling (乱画) a fish. But not just any fish. This fish was riding a skateboard and blowing a bubble that said "I'd rather be skating!"I laughed and drew a sea star saying "Quit fooling around and get to work!"

Just then, Ollie's grandma Abuela and her friend Mr. Goldberg came into the kitchen. Mr. Goldberg was in charge of the local animal shelter. Abuela poured their tea and inquired about how things were going at the animal shelter. Mr. Goldberg sighed, shaking his head. He explained that not enough people were adopting pets, resulting in too many animals without homes.

Overhearing the conversation, Ollie offered to adopt some excitedly. But Abuela said that one noisy parrot was plenty for this house.

"Blue isn't noisy," defended Ollie. "He's just musical."

"I'd have a whole farm full of animals if I could," I said. "But my parents say two cats and a hamster (仓鼠) are enough."

Mr. Goldberg said he kept trying to attract people to adopt animals, but found it hard to get people's attention these days. Ollie drew a sad whale, and I wrote the words "Please adopt me" in the shape of a whale spout (喷水). Mr. Goldberg took a look at our drawings and made favorable comments on them, saying that these clever talking animals just might grab people's attention. And he asked us if we were willing to design a poster for his animal shelter, a proposal we happily accepted. We decided to draw some ideas on our own and meet up again the next afternoon.

That night, when I was sitting in the living room brainstorming ideas for the poster, my little brother brought in our hamster, Mr. Nibbles, to give him a little run-around time. He made a hamster playground out of couch pillows and Mr. Nibbles began to run around merrily.

Suddenly, an idea formed in my mind.

We decided to make both Mr. Nibbles and Blue the stars of the poster.

To understand a painting, we're taught to look for color, composition, and light. But how can a painting (appreciate)by someone who's blind? Through touch, the one thing gallery signs tell you not (do). John Olson, a former (photograph)and his team turn paintings into fully textured 3D models.

The tactile(可触知的)paintings work as a way to show art to blind because we don't see with just Our eyes: We see with our brains. Research in the field of neuroplasticity-the brain's adaptability-shows that the visual cortex(大脑皮层)is made active by touch. Blind people recognize shapes with their (exist) senses, in a way similar to that of (sight )people, says Ella Striem-Amit, a Harvard scientist.

Luc Gandarias, who's now thirteen, went blind suddenly age seven. When he felt a 3D version of Leonardo da Vinci's "Mona Lisa" he (notice)her smile right away. "I can actually feel what you see when you look at it," he said.

For Luc, this means (independent). "The feeling of being able to see it to form my opinion is like breaking down another wall as a blind person."

Well, if certain people have their way, it'll go even further. We'll have microchips implanted (植入) into our brains that can interact with the computers by thought alone. It may sound like something from the science fiction, but in many ways, things look quite promising. Thanks to the ability to send and receive information remotely via computers, microchips and other related devices have long been put into brains.

For example, electrodes have been implanted in the brains of epilepsy patients to better record and even predict the abnormal neurological activity. Similarly, deep-brain stimulation, through implanted devices that cause activity in key brain regions, is an established treatment for things like Parkinson's disease, and is even being looked into for illnesses like depression.

However, it's another thing to place such devices in healthy individuals. There are the practical concerns, not least of which is what these chips will be made of. The inside of the brain is a mass of highly reactive chemicals and electrical activity. Implants would need to be inert (静止的) enough to not upset the delicate processes by their presence, but also sensitive enough to read and process the activity around them. Current technology has made impressive progress with this, but if it were to be rolled out to millions of people, we'd need to be 100 per cent certain that it's safe.

How many people will actually want to have technology literally put into their brain? A surprising 60 per cent of Americans say they'd be okay with it, but that's when it's purely theoretical. In reality, the possibility of having strangers stick chips in your brain is likely to prove unattractive, especially for a population where millions get mad at fictional microchips in vaccines (疫苗), and even more are frightened of dentists.

Ultimately, the technology of computer-brain interface (接口) implants is still far away from us.

Regardless of the sport, Cathy's attitude remains the same: Any athlete failing to respect nutrition is one who is failing to fulfill their potential. It's a key part of the training process. It's not just something that you take casually. She advises her athletes to hold nutrition in the same regard as they do their most crucial bit of equipment. "Just as you wouldn't forget to put your shin pads (护腿板) or your boots in your kit bag, don't forget to put in your drinks and your snacks. That informs how well you train, because you can't get out if you haven't put in."

Nutritionists are sometimes unfairly represented as militant (斗志昂扬的) types telling what athletes can and can't eat. But Cathy insists that when to eat is more important than what. "It's about when's the right time to have it in," she says. It's a message that Cathy says can take a while to sink in. "A lot of boxers say, ‘but bananas make you fat, right?', and there's this inherent belief that we mustn't eat those kinds of things. But it's not about what to cut out. It's about making sure that you've got the foundation right for health and performance. It's that one size fits one. It's what works for you. To be an excellent athlete, you really need to be an exceptional eater."

Together the engine and tender measured a little shy of 2 feet — enormous by the toy train standards of the day. Even better, the 746 had a working headlight and smoker, and its tender sang high.

Unfortunately, the amazing 746 also had an amazing price — $50, equal to about $450 today. That was far more than my grandfather could afford. Instead, I had to be content with his little Lionel plastic, which was SIX INCHES shorter than the 746 and had no headlight, no smoker or no sound! But that was the best that my grandfather could give me at that time.

Years passed, and I was in my 30s. Superior sound systems and computer controls dominated toy trains. I never gave a look. My interest in toy trains, I firmly believed, had faded, so did my admiration for the 746, since my grandfather was not with me. The 746 was never called to mind. On an ordinary day, however, I happened to see the 746 outside the window of a train show. Just one-look, I could not look away. Childhood memories that I tried to hide in the depths of my heart raced through my mind, happy or sad.

That day I took the 746 home and placed it in the center of the room, and let my childhood dream sing its way around me. Smoke rose out from the engine and the soft song sounded from its tender. It seemed as if I could see the soft light in grandfather's eyes and hear his cheerful laughter.

I taught English as a Second Language (ESL) at a school. One particular sixth grader, Pablo, was struggling with fluency in reading, so after class I suggested that he get extra practice by reading aloud to his mom while she prepared dinner each evening. This was something I routinely encouraged my struggling students to do. Imagine my surprise when Pablo responded by starting to cry. He said, "My mom can't cook dinner!" Then he cried harder. Eventually, he calmed down enough to tell me that his mom was only able to "cry in her bed" when he got home every afternoon. He said that he was caring for his six-month-old baby brother by himself from the time he got home each day. His mother, it seemed, had a bad tooth and was in extreme pain. He said that his father didn't have enough money to get it fixed, and that there was no way for her to go to a dentist. This child's heart was broken for his mom.

I was speechless! He was still crying when he left me that day, and I promised him I would try to help. I kept asking myself how I could help this student. How could I help his mother when we didn't even speak the same language?

The next day, I sent a note, which a friend helped me translate, to Pablo's mother asking if she would like me to find someone to help her. The following day, Pablo brought me a note from his mom accepting my offer to help.

Meanwhile, I had been doing some networking among my friends asking if anyone knew a dentist who might do some free work for this lady. At the time, I was not able to pay for the work to be done myself. Several friends suggested a dental office that had recently opened up in the area, thinking that they might be willing to provide the services. I didn't want to waste a lot of time going to several dentists, so I prayed that this would be the one.

China's first artificially-bred(人工繁殖) second-generation finless porpoise (江豚) is named Hanbao. The name's meaning is dividedtwo parts: "han" means it was born in Wuhan, Hubei province, "bao" means little baby in Chinese. As the fattest porpoise at a local Baiji dolphin museum in Wuhan, Hanbao(weigh) about 70 kilograms.

Finless porpoises, also called "smiling angels", have become sign of the health of the Yangtze River ecosystem. To prevent their extinction, finless porpoises have been bred artificially. Despite efforts to protect the finless porpoise for over 40 years,(it) numbers continued to fall. However, a scientific survey of Yangtze finless porpoises(carry) out on Oct 25 indicated the species' recovery. The change is owed to a 10-year fishing ban on the Yangtze River, began on Jan 1, 2021 and the Yangtze River Protection Law that came into effect two months later.

Because of these measures,(region) along the Yangtze River have relocated their chemical plants, restored wetlands and reorganized the sailing route. All these efforts(ultimate) improved the river's ecological environment,(help) to breathe life into the finless porpoise species.

That's why I decided to have a3 — hiking from Kazbegi Town to Gergeti Trinity Church. Though the trip is a short one, based on the church's location atop a mountain, I knew it was going to be a4 climb — especially after six weeks of traveling around.

I5 Kazbegi Town on a cold, foggy afternoon and decided to begin the hiking to the6 the next morning. Luckily, a(n)7 over the breakfast table at my guesthouse8 me. I got chatting with a couple who had done the hike and had a crucial9 for me: Don't follow the10 route, but instead, take the path on the left side of the mountain.

As it turned out, the main route — the route everyone else11 — was impossibly steep(陡峭的), but the lesser-walked path was a12 path along a mountain stream. Had I tried to take the main path, I never would have13 the walk; however, following this easier route, I14 something totally foreign: A hike I actually enjoyed! I felt so proud.

If it weren't for that first hiking in the Republic of Georgia, I don't think I would have had the courage to15 myself to other hikes.

In 2005, a terrible hurricane hit Kane's hometown. After it, she had to cope with the loss of her home. In watching the cardinals and other birds, she found relief. Soon she started bringing her students along. "My students stared at me in disbelief when I told them I had never cared about birds before," Kane writes. "I suddenly wondered how many creatures would die because of the way we lived." She decided to pursue an environmentally-conscious career. In 2007, she took a course to study environmental science.

Most of the book focuses on Kane's efforts to preserve Warner Park, an ideal location satisfying birding requirements for her class. She successfully campaigned to stop the construction of a parking lot. Her activism snowballed into a local bird watching and protecting organization. It eventually became part of Kane's doctoral research, and launched a birding class that pairs middle school students with college-student advisors.

The book shows readers that a good knowledge of nature doesn't require a degree. Take Jeremy, a seemingly uninterested boy in Kane's birding class. When reporters joined an outing, the normally quiet Jeremy started talking excitedly about the bunting, a small blue bird. Kane soon learned that he had secretly taken to studying the field guide given to him by his advisor.

At its core, Birding to Change the World is about how people and birds today depend on one another. "For birds, that dependence is concrete. For thousands of years, our species has seen birds as a symbol of liberation," Kane writes. In her case, it is liberation from the grief and depression that the hurricane brought. "Bird by bird, they carve a new pathway in my life, a joyful pathway."

During a match in May, Wu Chuguo, a decoration worker from Liubaitang village, Rongjiang County, scored a spectacular 40-meter goal that ignited (点燃) the crowd. Wu said he was influenced by elders in his village and fell in love with the sport. In the county, rural soccer matches have taken place regularly since the 1990s. When there was a lack of facilities, soccer players used barren land as a field and wooden stakes for the posts. The boundaries were marked out with lime powder. When they couldn't gather enough players, they played futsal, a soccer-based game played on a smaller hard court.

In recent years, the county has focused on gymnastics, soccer, rock climbing and other sports. What sets the Village Super League apart from other sports events are the vivid displays of ethnic cultures and traditions at the tournament. As players of both teams walk on the field for a game, they are accompanied by their cheering squads (啦啦队) dressed in traditional ethnic costumes and carrying local specialties. The halftime break features folk songs and dance performances, while ethnic costumes are also on display.

"hope that more and more tourists will come to Rongjiang to watch the matches, enjoy the folk customs and local cuisine, and have fun," said Xiong Zhuqing, a melon grower who is also a cheerleader. She says she has sold over 10,000 kilograms of watermelons since the start of the tournament. As of June 27, a total of 654 new businesses were established, including 91 in the catering sector, 188 in retail, and 195 in agriculture and food processing, the local government said.

I am often asked whether I feel at all sad when it's time to release the animals — to tell you the truth, I'm always pretty willing to let them go. All of my efforts have been toward allowing them to return to the wild, and the wild is where they belong, so there's no reason for reluctance on my part. But it is true that sometimes there is no way for an animal to go back to the wild, or to keep it from bonding with humans.

Last year, I rescued a light-vented bulbul (白头鹎). The bird, initially lacking feathers, recovered under our care. It was scheduled for release during its adolescent period, during which it's relatively easy to socialize. But an injury to its flight feathers delayed its return to the wild. The birdimprinted on humans during the following two months, which was a critical cognitive (认知的) development period, leading it to return to us after being released.

When we engage in wildlife rescue, we have to teach animals how to maintain a high degree of caution around humans. If they become too trusting of humans, it is very likely that way, our success depends not on the animals, or on our work here, but more so on the attitude humans would not be a bad thing, and our release attempt could then be successful.

This Portuguese ship sank off the coast of Oman in 1503. First discovered in 1998 and then extensively excavated (发掘) by a team led by David Mearns between 2013 and 2015, it is the oldest shipwreck (沉船) recovered from Europe's Age of Exploration.

Black Sea Shipwreck

Discovered in 2018 by a team from the Black Sea Maritime Archaeology Project, the ship sank more than 2,400 years ago. It is the oldest undamaged shipwreck ever found. "A ship in such good condition from the classical world, is something I would never have believed possible," said Professor Jon Adams, the principal investigator of the team that found the wreck.

Gribshunden

The flagship of John, King of Denmark, caught fire and sank in the Baltic Sea in 1495. There, it lay undiscovered until members of a local dive club came across it in the 1970s; unaware of its significance, they did not report it to archaeologists until 2000, and not until 2013 was the wreck's identity confirmed. Considered one of the best-preserved shipwrecks of the period, it has slowly been revealing its secrets.

Black Swan

In May 2007, a Florida-based company announced that, using underwater robots, it had discovered a shipwreck in the Atlantic, code-named (代号为) "Black Swan". However, the government of Spain claimed that the wreck was the Nuestra Senora de las Mercedes, a Spanish ship that sank off the coast of Portugal in 1804 following a battle with four British navy ships. After a long legal battle, the treasure was returned to Spain in 2012.

Susan had a secret: she loved robots. She had helped her dad in his workshop and knew a lot about motors, but her friends didn't know this.

One day, she heard Alex and Jacob talking about their robot, Robbie. They were preparing for a big competition but Robbie wasn't working properly. Susan was surprised by their courage, as they always seemed unpopular among the boys. She felt bad for them and wanted to help.

On the school bus home, Susan sat behind Alex and Jacob, who were still trying to fix their robot. "This is impossible! The legs move before you press the switch and stop after you press the switch!" Alex said, looking at Robbie's legs, which were not moving right. "The competition is only eight days away!" Jacob looked sad. He thought they were going to lose.

"Umm, how did you connect the wires from the switch?" Susan asked quietly over their shoulders. Alex turned and gave her a cautious look. Susan smiled and asked, "Did you connect the NO wire or the NC wire to the motor?" The boys stared at her as if she had just landed from Mars.

Susan gently took the robot and pointed out the wire connected to the motor. "Here's the problem!" She explained that it was the NC wire. It means the circuit (电路) is Normally Closed. She then pulled a loose wire out of the robot and explained that it was the NO wire, which means Normally Open. "If you connect this wire instead, Robbie will walk when you press the switch." Susan handed the robot back to Alex, who was staring at her with his mouth open.

"Change the wires and see," she said before getting off the bus. Ten minutes later, her phone rang. It was Jacob: "Your idea worked, and we're wondering if you could come over and help improve our Robbie." Susan smiled. She knew she had made the right choice.

Currently under construction off the country's northeast coast, the Dalian Jinzhou Bay International Airport will eventually cover 8-square-mile island with four runways and a 969,000 sq ft passenger terminal, according to an airport statement. Its operators aim (handle) 80 million passengers per year across 540,000 flights, with the first phase due to open in 2035. "The country's largest offshore airport is rising slowly from the sea level like the sunrise in the east," (read) a post by Dalian Jinzhou Bay International on Chinese social media platform WeChat. Once (accomplish), it will become the world's largest airport on an artificial island, surpassing both Hong Kong International Airport (HKG) and Japan's Kansai Airport (KIX). "There have been great challenges to the construction," Li Xiang, chief engineer of Dalian Airport Construction and Development Co., Ltd., told state-run local media in October, "as not only does the project have complex geological conditions and high drilling difficulty, high demand in quality with a tight construction schedule is another challenge we have to take into account."

As it is, it is the city of Dalian, with a population of 7.5 million, has long been a transport hub due to its proximity to Japan and South Korea. Dalian Zhoushuizi Airport, the city's international airport, has been operating for nearly a century, has already met its maximum capacity and (expand) several times these years, according to YiCai Global, a state-linked newspaper. The city started site selection and (demonstrate) work on the new airport in 2003, but construction only began in earnest a few years ago. China's aviation (boom) fast, new airports are a key part and surprisingly, the country is on track to pass the United States and become the world's largest air travel market.

Reggie didn't like it, but his friend Michael hated it more and decided things had to be3. He proposed the Day of Silence: in honour of Reggie, they should set aside one day for4 people, when everyone would have to wear earplugs (耳塞).

People liked the5. When the day arrived everyone stuck plugs in their ears, in a spirit of great6. That morning was filled with jokes and laughter. But, as the hours passed, people became aware of how7 life was when one couldn't hear anything.

However, that was nothing compared to the greatest8 of the day: Reggie was amazing! Just using his9 body language, he was the best to communicate with everyone. People paid more attention to what Reggie was saying, and were10 by his intelligence. They realized all Reggie needed was a little more11 to enable communication. That was the only12.

So on the Day of Silence, Reggie's true13 became known. And everyone realised you have to give people a chance to show how14 they are. They also learn that you couldn't hear the slightest thing until you truly15.
