Science fiction pioneer and writer Wu Yan won the National Outstanding Children's Literature Award in 2021 for his latest work China Orbit. The book focuses on the development of the Chinese aerospace (航空航天) industry, and it was inspired by the planning and preparation for China's first but canceled manned spaceship, "Shuguang 1", also known as Project 714, during the late 1960s and early 1970s.
"I collected many historical documents and stories and started writing decades ago," Wu said. Partly based on Wu's own experiences in the 1970s, the book is a combination of reality and fiction, and in some ways his own memoir (回忆录) is added into the science fiction. This innovative and unique writing method makes the book stand out and has even stirred up a debate on how to categorize it. Is it science fiction, popular science, children's literature, or aerospace literature?
His fellow science fiction writer Liu Cixin, author of The Three-Body Problem, sees it more deeply, and believes China Orbit is not really children's science fiction or popular science. He thinks it is too complicated to be classified into a single category. He speaks highly of China Orbit as a unique science fiction novel that vividly shows a child's real-life experience in a military camp (军营) of a specific era.
In Wu's opinion, China is a big market for children's science fiction, but it still lacks extraordinary works. He warned people not to try to earn quick money from it after The Three-Body Problem frenzy (狂热) and the movie The Wandering Earth, because Chinese science fiction still has a long way to go. "We need to build Chinese science fiction step by step with the accumulation of really great works. We need to innovate, and treat it as part of building China's new culture," Wu said.
For centuries, humans have explored the Earth's mountains, jungles and deserts. But despite covering over 70% of the Earth's surface, the ocean is still relatively a mystery. In fact, we know more about the surface of Mars than we learn about the sea floor. However, getting a fuller picture of the ocean would enable us to pilot ships more safely, create more accurate climate models, build offshore wind farms and protect ocean species — all part of what's known as the "blue economy".
Underwater robotic vehicles equipped with sensors are helping gather that data more quickly and more cheaply than ever before. But many of these vehicles rely on batteries with a limited lifespan, and need to return to a boat or the shore to recharge, making it difficult for them to map remoter parts of the sea.
A company called Seatrec is rising to the challenge, founded by oceanographer Yi Chao. While working at NASA, he developed a way to power ocean robots by making use of the naturally occurring temperature disparity of the sea. As the robot moves between colder and warmer parts of the ocean, the material inside the power module either melts or becomes solid, causing pressure that in turn creates energy and powers the robot's generator. "The ocean robots can get charged by the sea, so they can extend their lifetime almost indefinitely," Chao said.
The power module can be placed in existing data-gathering robots. The robot dives a kilometer down to examine the chemistry and the shape of the seabed, using sonar to create a map of the surrounding area. The robot returns to the surface to send back its findings via satellite.
The technology can extend the reach of data-gathering devices, according to Jamie McMichael-Phillips, director of the Nippon Foundation-GEBCO Seabed 2030 Project. "One of the huge challenges we have is simply physics: unlike mapping the Earth's surface where we can use cameras or satellites, at sea, the light can't go through the water column. So we're much limited to using sonar systems. Therefore, this technology can help deal with the problem well," said Jamie.
At Southmead Hospital in Bristol, researchers are experimenting with robots programmed to interact with patients for simple forms of physiotherapy (物理治疗). Another possible use might be basic bedside checks. Real applications are still some way off, but hospital leaders think this could help ease workforce pressure.
Everyone understands that people want more out of healthcare as they live longer. Hospitals have not enough workforce to meet those demands, and of course, robotics and technology can be taught to repeat unskilled tasks.
The hospital is working with Bristol Robotics Laboratory, looking at future care of patients in their own homes. This device can be controlled remotely to help with basic household tasks. Technology can clearly help those who need assistance at home, but might people feel they lose out from lack of human contact?
Professor Praminda Caleb-Solly at Bristol Robotics Laboratory said, "In no way are we looking to replace people, because nurses and doctors always think of what other people need and give them emotional support. The idea here is to improve the quality of care that can be provided. However, there are big questions over what that will mean for patients' experiences and the impact on staff. "
And away from patients, there's automation. Robots deliver most supplies around the hospital, including supplies to operating theatres and meals for the wards. They even have their own lifts. Because they do the heavy physical work, staff injuries have been reduced. Robot technology is also at work in the hospital drugstore. Orders for medicines are processed rapidly and made ready for clinical (临床的) teams. Pharmacists (药剂师) say it improves patient safety by eliminating (消除) human error.
Hugh Pym, BBC health editor, says that "robotic devices are thought to offer, potentially, major long-term benefits to hospitals. There's great potential there. " They won't necessarily offer cups of tea or even look like this. But the fact that hospital leaders are working with engineers on robotics shows there is a new vision for post-pandemic health and care.
I've learned seven languages well. Now I'm working on my eighth language. Many people ask me why I've learned so many languages well.
In order to learn a language well, it's important to find enjoyment in the process of learning. I've kept learning new languages because I really enjoy doing that. My enjoyment in the process keeps me going. You'll also need to use three more principles.
First of all, you need useful methods to memorize words. If you try to memorize a list of words for a test tomorrow, the words will be stored in your short-term memory. If you want to keep words in your mind longer, you need to review them in the course of a few days repeatedly. You can use apps which are based on this system.
We're all very busy and no one really has time to learn a language today. But we can squeeze that time if we just plan a bit ahead. Can you wake up 15 minutes earlier than you normally do? That would be the perfect time to review some words.
And finally, if you want to learn a language fluently, you also need a bit of patience. But it's certainly possible to make a visible improvement in two months, if you learn in small chunks every day in a way that you enjoy. And there is nothing that encourages us more than our own success.
A. But joy itself is not enough.
B. You'll forget them after a few days.
C. You should find your own enjoyment.
D,The second principle is to make a plan.
E. Today I'd like to share my secrets with you.
F. Don't lose hope if you make progress slowly.
G. It's impossible to learn a language within two months.
Our county had issued a stay-at-home order. This was 1 to help prevent the spread of COVID-19, but it made me 2 . How would my boys 3 the situation when cooped up (关起来) together for weeks on end?
My 15-year-old twins, Breckan and Brennan, 4 each other. If they were in the same room for more than 10 minutes, there was going to be a 5 . For years, our house functioned well with the boys in 6 spaces. That was why the order filled me with such 7 .
On the ninth day, I heard voices and laughter coming from Brennan's room. That sounded like my boys but it was 8 , I thought. Maybe it was the TV. I decided to go down the hall to 9 . I opened the door, and my breath caught in my throat. Both my sons were sitting on the edge of the bed, video game controllers in hand and 10 on their faces. Was I 11 things? Was it true that the boys 12 so well? A week later, I saw the twins showing each other how to perform better on the trampoline (蹦床). This was what I'd always 13 for! Filled with joy, I felt a little 14 when so much of the rest of the world was suffering during the pandemic.
In our house, there was more 15 than we'd ever known. I didn't 16 why. One evening, I stopped by Breckan's room for our nightly 17 before I went to bed. "Hey, what has happened between you and your brother 18 ?" I asked. Breckan shrugged, "I don't know, Mom. We've grown up, I guess. " Leave it to me, their mom, to try to 19 what has happened and put it into words! 20 , the whys and wherefores don't matter, really. What does matter is the love between them.
Some historians say that silk originated in China about 10,000 years ago. In China, however, legend (have) it that Empress Si Ling Chi of China was the first one (discover) silk more than five thousand years ago. The story goes while sitting under a mulberry (桑树)tree in her palace garden, the Empress was having tea. A cocoon fell into her hot cup of tea from the branches of the mulberry tree. And as she watched, a strong white thread spread gradually.
For more than two thousand years, the Chinese kept the secret of silk to themselves. Anyone found guilty of smuggling (偷运)silkworm eggs, cocoons, or mulberry seeds was put to (die). Silk became the cloth of emperors and royalty and a great source of wealth. But common people were prohibited wearing silk. Silk was gathered and kept in warehouses for emergency.
The Chinese used silk in many ways. Civil servants (pay) in quantities of silk, and it was a way for the rulers to reward their citizens. Silk was also used as currency in domestic as well as foreign trade. Chinese traders exchanged their silk in return for spices and jewels (buy) in India.
Later, people from different parts of society began wearing silk clothes, and (surprise) silk came into (much) general use than before.
Twenty years ago, I drove a taxi. Once, I was called at 3 a. m. to pick someone up. When I arrived, the building was completely dark except for one light in a window. Often, many drivers would just honk ( 按喇叭) once or twice, wait a short minute, then drive away.
But unless a real danger, I always went to the door to find the passenger. It might be someone who needed my assistance. Would I not want a driver to do the same if my mother or father had called for a taxi?
So I walked to the door and knocked. "Just a minute," answered a weak and elderly voice. I could hear the sound of something being dragged across the floor. After a long pause, the door opened. A small woman in her 80s stood before me. By her side was a small suitcase. "Would you carry my bag out to the car?" she said. "I'd like a few moments alone. Then, if you could come back and help me? I'm not very strong. "
I took the suitcase to the cab, then returned to assist the woman. She took my arm, and we walked slowly toward the cab. She kept thanking me for my kindness. "It's nothing," I told her. "I just try to treat my passengers the way I would want my mother treated. "
"Oh, you're such a good boy," she said. When we got in the taxi, she gave me an address. Then she asked, "Could you drive through the downtown?"
"It's not the shortest way," I answered. "I don't mind," she said, "I'm in no hurry. I'm on my way to the nursing home. " I saw her eyes shining with tears. "I don't have any family left," she continued. "The doctor says I am too old to live alone. "
I quietly turned off the meter (计程器). "What road do you want me to take?" I asked. "First, take me to Sunrise Street. That's where I was born. "
