Russia’s Soyuz spacecraft, which has been transporting all astronauts to and from the International Space Station(ISS)since 2011, typically carries a crew of three. However, the MS-14 capsule launched(发射)from a Russian spaceport in southern Kazakhstan on August 22, 2019, had just one passenger—a human-like robot named Skybot F-850.
The robot is the latest version of Russia’s FEDOR robots, which were initially designed to help with search and rescue efforts. Skybot is good at many human skills, including driving a car, having short conversations, and even telling jokes. But since it lacks some special sills, the spacecraft to the ISS was piloted from the ground by scientists from Russia’s space Agency. Roscosmos.
The six-foot-tall, 350-pound robot had another important task while on board. Without risking the lives of human astronauts, it helped Roscosmos researchers test the safety and flight experience of the new Soyuz-2.1, a carrier rocket, which carried the spacecraft into orbit. The feedback(反馈)will be important in determining if the rocket is safe to transport future human crews to space.
Though the launch into orbit went smoothly, Skybot’s arrival at the ISS was delayed by three days, from August 24 to August 27. The delay didn’t seem to bother the robot, which announced its arrival, “Sorry about the delay. Met with traffic. Ready to work now.”
Skybot’s two-week task is largely a test to measure its ability to work effectively in microgravity, and includes simple tasks like using tools. If all goes well, Russia hopes to send more advanced versions of the FEDOR robots to help astronauts with special tasks.
Earlier this year, the US space agency launched two little robots called Astrobees to help astronauts with daily chores, like finding lost pieces of equipment. Meanwhile, the European Space Agency’s social AI-powered CIMON spent a year assisting astronauts, before returning to Earth on August 27, 2019.

【推荐1】Bicycle riding has taken the world by storm. Bicycles are typically made of steel or aluminum but now there is a unique company that is growing bikes on trees, literally. These bicycles are made of British-grown ash trees by Welsh maker Andy Dix. His Hay-on-Wye company, Twmpa Frames, is making bikes that are of high performance and environmentally sustainable.
“It’s great to push for more bikes and fewer cars on the road, but there’s no escaping the fact that the bike industry as a whole is pretty energy intensive, ” Dix told Cycling Industry, “I’ve always tried to minimize environmental impact in my work. Rather than relying on heavily-processed metals, or layers of plastic that will one day end up in landfill, I’m building bikes from captured carbon, in a process powered by sunlight. ”
It took two years to build the prototype (雏形) that was made from ash wood. Dix tested the wooden bike on the roughest roads he could find and discovered that it was comfortable, durable, and excellent at absorbing shakes. He put more than 3, 000 miles on the bike. Dix explained, “I was running along battered roads that would have shaken me to bits on a aluminum bike. The penny dropped: Not only could I make a bike out of wood, but it had inherent advantages over other materials. ”
Though cutting down trees can add to more carbon in the atmosphere, sustainable tree farming is possible. Dix said that manufacturing a British tonne of aluminum results in carbon emissions of 4, 532 kg while producing a tonne of wood only emits 457 kg. Currently, the cost of a new Twmpa Cycle is out of reach for many bicycle riders; but the idea of using sustainable materials like ash trees could start a new cycling revolution that puts the environment first. Helping the environment could be just a pedal away.

【推荐2】Visitors to HENN-NA, a restaurant outside Nagasaki, Japan, are greeted by an odd sight: their food being prepared by a row of humanoid robots that look like the Terminator. H. I. S., the company that runs the restaurant, as well as a nearby hotel where robots check guests into their rooms and help with their luggage, turned to automation partly out of necessity. Japan’s population is shrinking, and its economy is booming; the unemployment rate is only 2.8 percent. “Using robots makes a lot of sense in a country like Japan,” said CEO Hideo Sawada.
Sawada predicts that 70 percent of the jobs at Japan’s hotels will be automated in the next five years. “It takes about a year to two to get your money back,” he said. “But since you can work them 24 hours a day, and they don’t need vacation, eventually it’s more cost-efficient to use the robot.”
This may seem like a vision of the future best suited—perhaps only suited—to Japan. But according to Michael Chui, a partner at the McKinsey Global Institute, many tasks in the food-service and accommodation industry are exactly the kind that are easily automated. Chui’s latest research estimates that 54 percent of the tasks workers perform in American restaurants and hotels could be automated using currently available technologies.
The robots, in fact, are already here. Chowbotics, a company in Redwood City, California, manufactures Sally, a boxy robot that prepares salads ordered on a touch screen. Botlr, a robot butler, now brings guests extra towels and toiletries in dozens of hotels around the country.
This seems to be worrying. America’s economy isn’t developing nearly as smoothly as Japan’s, and one of the few bright spots in recent years has been employment in restaurants and hotels, which have added more jobs than almost any other industry. That growth, in fact, has helped dull the blow that automation has delivered to other industries. The food-service and accommodation industry now employs 13. 7 million American. Since 2013, it has accounted for more jobs than manufacturing.
These new positions once seemed safe from robots because they required a human touch in a way that manufacturing or mining jobs did not. When ordering a coffee or checking into a hotel, human beings want to interact with other human beings—or so we thought. The companies bringing robots into the service industry are betting that we’ll be happy to trade our relationship with robotic waiters or clerks for greater efficiency. They’re also confident that adding robots won’t necessarily mean cutting human jobs.

【推荐3】Newcastle University research is helping to prepare for and relieve storm damage before extreme weather occurs. Climate experts and engineers have created a new model to predict the damage caused by extreme weather. This new framework for “consequence forecasting” enables first responders to effectively target resources before an extreme weather event comes, such as Storm Eunice.
The pre-event decision-making model works by first developing relationships between wind speed and faults on the electricity network. The relationships are then used to estimate faults of electricity networks and potential customer interruptions. This model can be used as early as 24 hours before extreme weather events.
Published in the journal Climate Risk Management, the study findings can enable effective first response to manage infrastructure (基础设施) systems smitten by dangerous weather. Having the forecasting tools to predict and prepare for storm damage will reduce the social consequences of extreme weather, including power loss for customers and fines for electrical distribution companies.
Dr Wilkinson said, “Our model has the potential to change the way we manage weather and climate risks to our infrastructure networks. While electricity network operators already prepare extra resources when a storm approaches, predicting how many power lines may be blown down and where these are likely to be located will allow them to better target the necessary resources to more quickly repair any damage. This is likely to become even more important in the future as our changed climate is predicted to produce more frequent and more intense storms and some of these may be beyond the experience of the people tasked to deal with them.”
Study co-author, Professor Hayley Fowler, of Newcastle University’s School of Engineering, added, “This consequence forecasting is so important for planning emergency response in fast-evolving storms like Eunice. Our model could be used to regularly update energy companies and other infrastructure operators on the potential consequences of approaching storms as forecasts are updated in real-time.”

【推荐1】Born and raised in a digital age, today’s young people are generally tech savvy (技术娴熟的). But when it comes to basic life skills, they’re less capable than the older generation.
According to a recent study, 69 percent of 18 to 24-year-olds in the UK have no idea how to bleed a radiator(暖气片换水). About 35 percent of them don’t know how to sew on a button, while about 11 percent don’t understand how to change a light bulb or iron clothes.
It appears young people are losing the skills older generations took for granted. In fact, the problem is shared by young people in the United States. According to a report by Forbes in 2014, most millennial (千禧一代) drivers don’t know how to check their tire pressure. Cooking is another basic life skill that has been dropped, as millennials are much more likely to order food deliveries than previous generations.
Technology may be to blame for this generational gap. Skills at using phones and computers are the ones valued these days, and the practical skills are now seen as functions that can be easily outsourced (外包). Indeed, improvements in technology have made young people unfamiliar with many basic life skills. For example, with GPS always at hand, young people have had no need to learn how to read physical maps.
However, this change has raised concerns among many people. “If you have your master’s degree and you can’t live within your means or go home from your job and feed yourself a nutritious (有营养的) meal, you’re not a complete graduate,” Chris Moore, a professor from Brigham Young University, US, told HuffPost.
That’s why there’s an increasing call for the return of “home ec” in the US, short for home economics, which teaches basic life skills like cooking and how to do laundry. It was very popular in the early 20th century, but was later taken out of schools and universities because of budget(预算) cuts. But recently, home ec was reintroduced in a small number of schools and universities.
“The educational system would work better if every academic class had a practical course that applied the theory to do something regular people do in real life,” Robert Frost, instructor and flight controller at NASA, wrote on Quora, according to Huffpost.

【推荐2】NBA commissioner David Stern was in Orlando on Thursday night, getting ready for Sunday’s All-Star Game. Of course, all he could talk about was the only player anyone wants to talk about these days: New York Knicks guard Jeremy Lin.
Hours before Lin took the court against the Heat, a few hundred miles South down I-95 in Miami, Stern told reporters that Lin’s instant popularity hasn’t ever been matched in sports history, not even by Sunday’s biggest names, LeBron James or Kobe Bryant.
The Associated Press had the details.
“I haven’t done a calculation, but it’s fair to say that no player has created the interest and the craze in this short period of time, in any sport, that I’m aware of like Jeremy Lin has,” Stern said Thursday.
Lin, an undrafted(未选秀的)guard from Harvard, has become the NBA’s biggest story since coming off the Knicks’ bench earlier this month to lead them to nine wins in 11 games heading into their matchup with Miami on Thursday night.
With Lin’s popularity in Asia as the league’s first American-born player of Chinese or Taiwanese descent, and with the religious community because of his strong Christian faith, Stern says he’s “never quite seen anything like” the attention on Lin.
“It’s fascinating,” Stern said after the All-Star Jam Session opening ceremonies.
The top five videos on NBA.com since Feb. 4, when Lin joined the circulation, are all Lin or Knicks related. Lin went from 190,000 followers on Sina, China’s version of Twitter, on Feb. 2 to more than 1 million as of Feb. 16.
Indeed, Lin’s popularity is so out of this world that the NBA made a late list switch to ensure his participation in the Rising Stars Challenge on All-Star Saturday, a game that includes the NBA’s best rookies(新秀球员)and sophomores. Lin is in such high demand that all of the game’s other participants will meet with the media following a team practice on Friday while Lin will have his own, separate press conference later in the night.
This is Jeremy’s world, folks. We’re all just living in it. Even David Stern and the rest of the league’s All-Stars, at least for the moment.
1. The following statements about Jeremy Lin’s instant popularity are true EXCEPT that ______.A.Jeremy Lin led New York Knicks to win all the recent games this month |
B.David Stern said Lin was the only instant popular player in NBA’s history |
C.Lin has become the NBA’s greatest story though he was an undrafted guard |
D.no player has created the interest and the enthusiasm in such a short period of time |
A.Because Jeremy Lin was born in Taiwan with strong Christian faith. |
B.Maybe because he is the first player born in America but has Chinese descent. |
C.Because Sina has a large group of surfing people, maybe more than 10 million. |
D.Because the top five videos on NBA. com since Feb. 4 are all Lin or Knicks related. |
A.impossible | B.important | C.exceptional | D.excellent |
A.Knowledge starts with practice. | B.Failure is the mother of success. |

Prince Charles yesterday promised to reduce the royal impact on the environment through sweeping changes to his personal lifestyle and official schedule. The prince will replace carbon-heavy private jets and helicopters with scheduled flights and train services.
The move came as Prince Charles urged business leaders to publish the environmental pact of their activities.
He said, “Few accountants and business decision-makers ask, ‘How much of our critical natural resource is left? How many miles of polar ice cap has our business helped melt this year? By how many inches have we raised sea levels? How many species have we put at risk? How many homes will be flooded, how many people will die of thirst or starvation because of our activities? ’ These are not comfortable questions, but, by God, they need to be asked. ”
He added, “At the moment these costs do not appear in anyone’s books… Yet they are real, they are incurred now and in a relatively short time, the damage being caused may be beyond remedy. ” He said the world was “running up the biggest global credit card debt in history, but with little or no thought for how the bill will ever be paid”.
Flanked by the prime minister and business and community leaders at St James’ Palace, the prince said his new “accounting for sustainability” project would give consumers the power to choose products that caused less damage to the planet.
Duchy Originals, the prince’s food company, is taking steps to work out how much carbon dioxide and other green-house gases are emitted in growing, processing and distributing its products. The changes to the prince’s travel arrangements announced yesterday are part of a wider review of the carbon footprint associated with activities at all three of his residences. Clarence House in London, Highgrove and Birkhall on the Balmorals estate(庄园), as well as the activities of his 21 personal and 105 full-time staff. Measures include a review of electricity use, commuter and other staff travel and are intended to identify further reductions in carbon dioxide emissions. The review will report in June , when Clarence House will announce annual targets to reduce carbon emission.

C.Doubtful. | D.Impatient. |
A.make as much green food as possible |
B.cut down its cost |

【推荐1】A remote control is seemingly capable of invisible magic to most of us. We just assume it should. And the longer a given technology exits, the more we take it for granted.
Consider for a moment a split screen showing modern remote control users versus the first remote control users: the original users would be carefully aiming the remote directly at the television, reading the names of the buttons to find the right one, and intentionally pressing the button with a force that adds nothing to the effectiveness of the device. The modern users would be leaning on a sofa, pointing the remote any which way instinctively(本能的)feeling for the button they desired,intuiting(凭直觉知道)its size,shape, and position on the remote.
Humans are known for being handy with tools, so it is no surprise that we get so comfortable with our technology. However, as we become increasingly comfortable with how to use new technologies, we become less aware of how they work. Most people who use modern technology know nothing of its underlying science. They have spent neither mental nor financial resources on its development. And yet, rather than be humbled(使谦逊)by its originality, we consumers often become unfairly demanding of what our technology Should do for us.
Many of the landmark inventions of the twentieth century followed predictable tracks: initial versions of each technology (television, video games, computers, cell phones, etc.) succeeded in impressing the general public. Then, these wonderful new inventions quickly became commonplace. Soon, the focus of consumer attitudes towards them changed from gratitude with respect to discriminating preference.
Televisions needed to be bigger and have a higher resolution. Video games needed to be more realistic. Computers needed to be more powerful yet smaller in size. Cell phones needed to be smaller yet capable of performing other tasks such as taking pictures, accessing the Internet, and even playing movies.
For children of the last twenty years born into this modern life,these technological marvels seem like elements of the periodic table: a given ingredient that is simply part of the universe. Younger generations don't even try to imagine life without modern conveniences. They do not appreciate theunprecedented(史无前例的)technology that is in their possession; rather, they complain about the ways in which it fails to live up to ideal expectations. “My digital video recorder at home doesn't allow me to program it from my computer at work.” “It's taking too long for this interactive map to display on my portable GPS”.
If it sounds as though we're never satisfied, we aren't. Of course, our complaints do actually motivate engineers to continually refine their products. After all. at the root of our tool-making instinct is the notion (观念)that “there must be a better way.” Thus, the shortcomings of any current version of technology are pinned on the limitations of its designers, and the expectation is that someone, somewhere is working on how to make the existing product even better.
1. The second paragraph is used to suggest that______________.A.modern humans do not pay enough attention to instructions |
B.remote controls have become far more effective over the years |
C.consumer behavior toward new forms of technology changes over time |
D.the first consumers of new technology used new devices with ease and comfort |

【推荐2】Sleep is essential for a person’s wellbeing. Researchers have found that sleep loss increases a person’s risk of developing serious medical conditions. Now, a new study has found that getting enough sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research, was not trying to find the correlation (相关性) between sleep and grades when he handed out Fitbits to the students in his class. Instead, the professor hoped the popular wrist-worn electronic device (装置), which tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
As part of the research, a quarter of the participants chose a fitness class specially created for the study. After the school term ended, the researchers carefully analysed the data. Much to Grossman’s surprise, they found no measurable difference in test performance between the group that had been physically active and the group that had not.
However, the study presented a surprising viewpoint in the journal Science of Learning. Going through the large amount of data, Grossman noticed an interesting trend (走向) from the participants sleep patterns. There was a straight-line relationship between the average amount of sleep and his/her grade on the exams.
Besides, it was not enough for students to just head to bed early the night before a test. Grossman says: “We’ve heard the phrase ‘Get a good night’s sleep, you’ve got a big day tomorrow.’ It turns out this does not relate at all to test performance. Instead, it’s the sleep you get during the days when learning is happening that matters most.”
The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student.
The research does not prove that sleep is the only component that helps improve academic performance. However, Grossman says the results are a strong indication that sleep really matters. Who knew getting A’s just required some extra ZZZ’s?

【推荐3】For most of us, work is the central, dominating fact of life. We spend more than half our conscious hours at work, preparing for work, traveling to and from work. What we do there largely determines our standard of living and our status to a considerable extent. It is sometimes said that because leisure has become more important, the injustices of work can be pushed into a corner, and that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. For the foreseeable future, however, the material and psychological rewards which work can provide will continue to play a vital part in determining the satisfaction that life can offer.
Yet only a small minority can control the pace at which they work or the conditions where their work is done; only for a small minority does work offer scope for creativity, imagination or initiative.
Inequality at work is still one of the most glaring (明显的) forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial life, many of which arise from the frustrations created by inequality at work, unless we handle it determinedly.
The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning. They are able to exercise responsibility. They have a considerable degree of control over their own and others’ working lives. Most important of all, they have opportunities to initiate. By contrast, for most manual workers, work is a boring, dull, even painful experience. They spend all their working lives in intolerable conditions. The majority have little control over their work. It provides them with no opportunity for personal development. Many jobs are so routine that workers feel themselves to be mere cogs (齿轮) in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated (疏远) from their work and their firm.

【推荐1】I’d done it before, and so I had no reason to believe that this time would be any different . I was sure that when I returned home from my mission trip. as always, I'd bring back nothing more some mud on my boots. a hole or two in my jeans and, of course, a lot of great memories.
The summer before my high school graduation, I went to West Virginia with others as volunteers to repair the homes of those in need. Arriving at our destination, my group was assigned the task of rebuilding sections of a home that had been damaged by fire. No sooner had we parked on the home's dirt driveway than we saw an excited little girl, no more than six years old, standing in the doorway of the family's temporary home. Shoeless and wearing dirty clothes and the biggest smile I'd ever seen, she yelled, "Ma, Ma, they really came!" I didn't know it then, but her name was Dakota, and four more days would pass before she'd say another word near me.
Behind Dakota was a woman in a wheelchair-her grandmother, we'd soon learn. I also discovered that my job that week would be to help change a fire-damaged dining room into a bedroom for this little girl. Grabbing our tools, we went to work. Over the following days, I noticed Dakota peeking at us every now and then as we worked. A few times, I tried talking with her, but she remained shy and distant, always flying around us like a tiny butterfly but keeping to herself.
By our fifth and final day, however, this was about to change. Before I went to work on her home on that last morning, I spoke for a moment or two with the grandmother. I was especially pleased when she told me how much Dakota loved her new room-so much, in fact, that she'd begged to sleep in it the previous night, even though it wasn't quite ready. As we talked, I noticed something I hadn't seen before-Dakota was hiding behind her grandmother.
Cautiously, she stepped into view, and I could see that just like her clothes, her face was still dirty. But no amount of soil could hide those bright blue eyes and big smile. She was simply adorable. I wanted so much to hug her, but respecting her shyness, I kept my distance.
Slowly, she began walking toward me. It wasn't until she was just inches away that I noticed the folded piece of paper in her tiny hand. Silently, she reached up and handed it to me. Once unfolded, I looked at the drawing she'd made with her broken crayons on the back of an old coloring book cover. It was of two girls-one much taller than the other-and they were holding hands. She told me it was supposed to be me and her, and on the bottom of the paper were three little words that instantly broke my heart Now almost in tears, I couldn't control myself anymore-I bent down and hugged her. She hugged me, too. And for the longest time, neither one of us could let go.
By early afternoon, we finished Dakota's bedroom, and so I gladly used the rare free time to get to know my newest friend. Sitting under a tree away from the others, we shared a few apples while she told me about her life. As I listened to her stories about the struggles she and her family went through daily, I began to realize how boring various aspects of my own life were.
I left for home early the next morning. I was returning with muddy boots and holes in my Jeans. But because of Dakota, I brought back something else, too-a greater appreciation for all or the blessings of my life. I'll never forget that barefoot little butterfly with the big smile and dirty face. I pray that she'll never forget me either.

【推荐2】In 1957, Max Vernon Mathews wrote the first computer program called Music, which enabled a computer to create sound and play it back. He was then working as an engineer at Bell Laboratories in New Jersey. It enabled a large IBM computer to play a seventeensecond piece of music he had written.
The computer was so slow that it took an hour to play the seventeensecond piece of music. So Mathews moved the work to a tape player to play the music at a normal speed. He later said that the sound quality of the musical notes was not great, but the technical importance of the music was huge.
The science fiction writer Arthur C. Clarke visited Bell Laboratories in the 1960s. He heard a computer “sing” the song Daisy Bell on devices (设备) and learned about the programs developed by Mathews and other engineers. Clarke noted this technology in his book 2001: A Space Odyssey, which was later made into a movie.
Mathews continued creating other versions of the Music program. He became interested in how computers could help musicians outside recording studios. The Groove program he developed was the first computer program made for live performances.
He also developed an electronic device he called the Radio Baton, which looks like two drum sticks. It enables the user to control the speed and sound levels of orchestral music (管弦乐) played on a computer by moving the two sticks on a special electronic surface.
Mathews said he believed modern musicians were not making full use of the power of computer music. He said a violin always sounds like a violin. But with his Music, the way a violin sounds is unlimited. He did not want computer sounds to replace live music, but he hoped computers would one day be considered serious instruments.

【推荐3】On a freezing January morning Jonny Benjamin, then a 20-year-old college student, climbed on the edge of Waterloo Bridge in London. That morning, Jonny escaped from a mental health hospital, where he’d been diagnosed (诊断) with schizo-affective disorder. He headed straight to the bridge, convinced that his disease was a life sentence.
Hundreds of people passed by. Only one man called Neil Lay bourn, then 25, calmly and quietly walked to Jonny’s side.
“You’re alright, man? Why are you sitting on a bridge?”
At first Jonny wanted Neil to leave him alone, but something in Neil’s calm, down-to-earth manner struck a chord. Jonny felt faith, like he could talk to him.
“It’s cold here. Why not have some coffee in a warm cafe? Everything will be OK.” For the first time after the diagnosis Jonny Celt perhaps it really might. He climbed back.
The police, having received calls from passers-by, were waiting there. They quickly put him into a police car, in case he was to panic and jump. He lost sight of Neil, the person who’d brought him hope.
Jonny ended up back in hospital. Eventually, he was well enough to return to university and finish his degree. Over the next six years, Jonny often thought about the stranger who had talked him round. Eager to thank him in person, he posted a Facebook message nicknaming the good man Mike. His #Find-Mike post was shared millions of times around the world, as far as Canada.
Jonny was overexcited when Neil called him two weeks after his post. They had a reunion, finally having that coffee they had first planned all those years ago.
“Many people walked past, but because of Neil’s kindness and sympathy, I’ve lived a good life.” Jonny said.
