1 . A robot with a sense of touch may one day feel “pain”, both its own physical pain and sympathy for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.
Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial “pain nervous system,” as Asada calls it, may be a small building block for a machine that could ultimately experience pain. Such a feeling might also allow a robot to “sympathize” with a human companion’s suffering.
Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic looking child’s head, these touch and pain signals can be converted to emotional facial expressions.
A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin “allows the possibility of engagement in truly intelligent ways”.
Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care for people in need, the elderly, for instance.
But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that’s able to compute an internal feeling accurately, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is “along the lines of having a robot, for example, that smiles when you talk to it,” Damasio says. ‘It’s a device for communication of the machine to a human.” While that’s an interesting development, “it’s not the same thing” as a robot designed to compute some sort of internal experience, he says.

2 . Starman, the dummy(仿真人) riding a cherry-red Tesla Roadster(特斯拉敞篷车) through space, has made his closest approach ever to Mars. The electric roadster and its passenger were attached to the top of a Falcon Heavy rocket during the SpaceX rocket’s first test launch on 6 February 2018.
Two years later, the Falcon Heavy rocket and the vehicle at its tip are making their second trip around the Sun. Mr. McDowell, a Harvard astrophysicist, found that Starman passed 7.4 million kilometers from Mars at 06:25 GMT 7 October, 2020.
The closest recent approach between the Earth and Mars was 56 million kilometers in 2003, though the planets are often hundreds of millions of miles apart depending on where they are in their orbits. No one can see the Falcon Heavy rocket at its current distance, but orbits over periods of a few years are fairly straightforward to predict, and Mr. McDowell used data about how the rocket was moving when it left the Earth’s gravity behind to locate its recent movements exactly.
Last time Starman circled the Sun, McDowell said, it crossed Mars’ orbit while the Red Planet was quite far away. But this time the crossing lined up with a fairly close approach, though still not close enough to feel a strong tug from Mars.
At this point in time, if you were able to go look at the Roadster, it would probably look pretty different. The strong solar radiation environment between the planets would probably have destroyed all the exposed organic materials.
Without the Earth’s atmospheric and magnetic(磁场的) protection, even the plastics and carbon-fibre materials would start to break up. Over the course of decades or centuries, the car will end up with its aluminium(铝) frame and hard glass parts----that’s assuming that none of them get destroyed in impacts with passing space rocks.

3 . The world can be a scary place when you' re young. It can be even scarier when you' re a young little blue penguin(企鹅) , the tiniest of the penguin species. Luckily, there are some humans willing to help. They stepped in to protect Billy, a blue penguin that appeared on a beach in Christchurch, New Zealand.
Spotted on November 29 at the slipway at Moncks Bay, near Sumner，in Christchurch，the little penguin immediately attracted a small crowd. Jeff Mein Smith saw the crowd while he was bicycling that afternoon, and he biked home to get his camera. When he returned to the scene，he found that the penguin had received a little sign, one that read “Hi, I'm waiting for my mum to come back. DOC(Department of Conservation) knows I'm here. Please leave me alone. Keep your dog away. Thanks, Billy the baby blue penguin.”
Billy didn't move away from the sign. The DOC arrived later that afternoon to pick up Billy, though they were surprised to see it on the beach. “It's unusual for a blue penguin to be out in the open on the beach during the day, ”Anita Spencer, a DOC senior ranger, told Stuff.
Billy was taken to the Christchurch Penguin Rehabilitation Center after being retrieved from the beach. Volunteers believe the bird may actually be a female penguin, and is around 2 months old. The chick weighs a mere 550 grams, less than a standard basketball. A blue penguin should weigh around 900 grams at this age. Most little penguins grow up to weigh 1 kilogram.
The center will help the little penguin gain some weight by feeding it fish juice, before it's set free into the ocean.

4 . This is the moment a cleaner at a British university burst into tears after students raised $ 2,063 to send him to Jamaica on vacation to see family.
Herman Gordon, who has worked at Bristol University for more than a decade, is described as “one of the most loved” members of its cleaning staff. He is so well liked that a group of students raised money to give him a holiday. A video shows a student hands an envelope of cash to the surprised Gordan with tears rolling down his cheeks. He wipes away tears with a cleaning cloth and hugs the student who gave it to him. Gordan said: “I want to thank every one of you and God bless every one of you.”
The group of students started the fundraising because they liked Gordon so much. A post said: “The Jamaican cleaner in the biomedical library is the jolliest man I have ever met; he makes me smile even when I’m in the deepest depths of sorrow, if you want a reason to smile, go talk to him for a minute or two.”
Anyone who has been to the biomedical library knows who Herman the cleaner is. Simply put, Herman is the epitome（典范）of happiness, “All year round, this man works hours on end to provide us with a clean working space in which to study. But most importantly, his everlasting positive attitude has managed to turn many students’ dark days into positive ones filled with joy,” said a student. Whether you’re just feeling generally down or stressed out due to exams, Herman is always there to encourage you.
This legend proves that happiness is not about what you own, what job you have or how much money you’ve got, but about appreciating what you currently have in life even if it’s small.
1. What was Herman Gordon’ reaction when receiving the fundraising?| A．grateful. | B．stressed. | C．delighted. | D．astonished. |

5 . We recognize our friends’ faces. And we’re not alone. Many social animals can identify individuals of their own species by features of their faces. That's important, because they need to be able to change their behavior depending on who they meet. And a recent research has shown that some species of monkeys, birds, and domesticated (家养的) animals can even tell different faces apart by looking at photographs alone.
Ethologist Léa Lansade of the French National Research Institute for Agriculture, Food and Environment did an experiment to find out how well horses can recognize individual people in photographs.
She and her team first taught the horses how to “choose” between two side-by-side pictures by touching their noses to a computer screen. The horses were then shown photos of their present keeper alongside faces of unfamiliar humans. They had never seen photos of any of the people before. The horses correctly identified their current keeper and ignored (忽视) the stranger’s face about 75%of the time. In fact, even though the horses didn't get it right every single time, they were at least as correct in picking out their earlier keeper as they were at identifying their present one.
The results suggest that not only can horses differentiate between familiar and unfamiliar human faces, they also naturally understand that photographs are two dimensional representations (二维呈现) of real life, without any other intimations such as smell or sound. And they’re even better at this than our oldest animal parter, the domestic dog.
In addition, horses seem to have a strong long-term memory for human faces, like their long lifespan and history of domestication. In future experiments, the researchers would like to test whether looking at photos of people that they have had bad experiences with in the past might cause horses to act anxious or even avoidance. So maybe think twice before doing anything that might give a horse a long face.

6 . Recently I read Nineteen Eighty-Four, a novel by George Orwell set in a state where even the language they use is controlled. Adjectives are forbidden and instead they use phrases such as ‘ungood’, ‘plus good’ and ‘double plus good’ to express emotions. As I first read this I thought how impossible it would be in our society to have such vocabulary. However, the more I thought about it, the more I realised in its own way it’s already happening. I type messages to my friends and alongside each is the emoji. I often use them to emphasise something, or to not seem too serious, or because this specific GIF conveys my emotions much better than I ever could using just words. And I wonder, with our excessive use of emojis, are we losing the beauty and diversity of our vocabulary?
English has the largest vocabulary in the world, with over one million words, but who’s to say what it’ll be like in the future? Perhaps we will have a shorter language, full of saying ‘cry face’ if something sad happens or using abbreviations (缩写) like LOL (laugh out loud) or BRB (be right back) instead of saying the full phrase. So does this mean our vocabulary will shrink? Is it the start of an exciting new era? Will they look back on us in the future and say this is where it all began – the new language? Or is this a classic case of the older generations saying, ‘Things weren’t like that when I was younger. We didn’t use emoticons to show our emotions’?
Yet when you look back over time, the power of image has always been there. Even in the prehistoric era they used imagery to communicate, and what’s even more incredible is that we are able to analyse those drawings and understand the meaning of them thousands of years later. Pictures have the ability to transcend time and language. Images, be it cave paintings or emojis, allow us to convey a message that’s not restrictive but rather universal.

| D．Emojis will not restrict our communication. |
7 . The human face is a remarkable piece of work. The astonishing variety of facial features helps people recognize each other and is important to the formation of complex societies. So is the face’s ability to send emotional signals, whether through an unconscious reddening of face or a false smile. People spend much of their waking lives, in the office and the courtroom as well as the bar and the bedroom, reading faces, for signs of attraction, trust and cheat. They also spend plenty of time trying to dissimulate.
Technology is rapidly catching up with the human ability to read faces. In America, facial recognition is used by churches to track prayers’ attendance; in Britain, by shopkeepers to spot past thieves. This year Welsh police used it to arrest a suspect outside a football game. In China, it verifies the identities of ride-hailing (网约车) drivers, permits tourists to enter attractions and lets people pay for things with a smile. Apple’s new iPhone is expected to use it to unlock the home screen.
Compared with human skills, such applications might expand steadily in scale. Some breakthroughs, such as flight or the Internet, obviously transform human abilities; facial recognition seems merely to encode them. Although faces are peculiar to individuals, they are also public, so technology does not, at first sight, intrude on something that is private. And yet the ability to record, store and analyse images of faces cheaply, quickly and on a vast scale promises one day to bring about major changes to our understanding of privacy, fairness and trust.
Start with privacy. One big difference between faces and other biometric (计量生物学的) data, such as fingerprints, is that they work at a distance. Anyone with a phone can take a picture for facial-recognition programs to use. FindFace, an app in Russia, compares snaps of strangers with pictures on VKontakte, a social network, and can identify people with a 70% accuracy rate. Even if private firms are unable to join the dots between images and identity, the state often can. Photographs of half of America’s adult population are stored in databases that can be used by the FBI. Law-enforcement agencies now have a powerful weapon in their ability to track criminals, but at enormous potential cost to citizens’ privacy.

8 . As new technology is introduced, there are many who worry about its influence on our current and future lifestyles－particularly when it comes to jobs. It is a current belief that with the rise of automation and artificial intelligence (AI), many people’s jobs, and therefore their livelihoods, are likely to be lost.
Automation in the workplace is nothing new. Machines have been performing dull tasks on our behalf for years, allowing us to escape many repetitive jobs. A recent report from the McKinsey Global Institute states that nearly two thirds of all jobs could have at least 30% of their activities automated by 2030. However, McKinsey also believes that this new technology will also ‘create new occupations that do not exist today, much as technologies in the past have done.’ As the horse gave way to the car, hostlers (马夫) became mechanics and mechanised fields drove up wages and created more long-term roles than it destroyed.
“It’s an evolution of work,” says Ian Barkin, a robotic process automation specialist. As low-skilled jobs are taken on by AI, people will need to learn new skills. “This calls on us to focus on up-skilling. Technology can lead to job reductions but it doesn’t have to,” says Barkin.
Whether or not robots and AI will leave us all jobless remains to be seen. Current views on the subject are mixed. Increased automation could indeed lead to a loss of some jobs, but at the same time is likely to create many more as new skills are required. Will they balance out?
1. How do many people feel about the influence of AI?| A．Quite delighted. | B．Quite surprised. |
| C．A sense of fear. | D．A sense of pride. |
| A．Doubtful. | B．Negative. |

| D．A bad workman quarrels with his tools. |
9 . Most of us marry creativity to our concept of self either we're "creative" or we aren't, without much of a middle ground. "I'm just not a creative person!" a frustrated student might say in art class, while another might blame her talent at painting for her difficulties in math, giving a comment such as, "I'm very right-brained."
Dr. Pillay, a tech entrepreneur and an assistant professor at Harvard University, has been challenging these ideas. He believes that the key to unlocking your creative potential is to ignore the traditional advice that urges you to "believe in yourself." In fact, you should do the opposite: Believe you are someone else.
Dr. Pillay points to a 2016 study demonstrating the impact of stereotypes on one's behavior; The authors. educational psychologists Denis Dumas and Kevin Dunbar, divided their college student subjects into three groups, instructing the members of one to think of themselves as "romantic poets" and the members of another to imagine they were "serious librarians" (the third group was the control). The researchers then presented all the participants with ten ordinary objects, including a fork, a carrot, and a pair of pants, and asked them to come up with as many different uses as possible for each one. Those who were asked to imagine themselves as romantic poets came up with the widest range of ideas, whereas those in the serious-librarian group had the fewest. Meanwhile, the researchers found only small differences in students' creativity levels across academic majors.
These results suggest that creativity is not a fixed individual characteristic but a "malleable product of context and perspective, as long as he or she feels like a creative person. Dr. Pillay argues that, besides identifying yourself as creative, taking the bold, creative step of imagining you are somebody else is even more powerful. So, wish you were more creative? Just pretend!
1. According to the passage， who is more likely to unlock his creative potential?| A．An art major who always believes in himself. |
| B．A math major who has excellent academic performance |
| C．A physics major who likes to imagine himself as a poet. |
| D．A history major who works as a librarian on weekends. |
| A．The creativity of the college students. |
| B．The stereotypes of the college students. |
| C．The impact of stereotypes on one's behavior |
| D．The influence of creativity on one's behavior. |
| A．stable | B．sustainable | C．predicable | D．changeable |
| A．there is no doubt that we are either creative or not |
| B．a student who doesn't do well in art class is not creative |
| C．right brain determines whether a person is creative or not |
| D．if we pretend to be creative， then we might be really creative |
10 . British anthropologists Russell Hill and Robert Barton of the University of Durham, after studying the results of one-on-one boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling matches at the Olympic Games, conclude that when two competitors are equally matched in fitness and skill, the athlete wearing red is more likely to win.
Hill and Barton report that when one competitor is much better than the other, colour has no effect on the result. However, when there is only a small difference between them, the effect of colour is enough to tip the balance. The anthropologists say that the number of times red wins is not simply by chance, but that these results are statistically significant.
Joanna Setchell, a primate (灵长目动物) researcher at the University of Cambridge, has found similar results in nature. She studies the large African monkeys known as mandrills. Mandrills have bright red noses that stand out against their white faces. Setchell’s work shows that the powerful males—the ones who are more successful with females—have a brighter red nose than other males.
As well as the studies on primates by Setchell, another study shows the effect of red among birds. In an experiment, scientists put red plastic rings on the legs of male zebra finches and this increased the birds’ success with female zebra finches. Zebra finches already have bright red beaks (鸟喙), so this study suggests that, as with Olympic athletes, an extra flash of red is significant. In fact, researchers from the University of Glasgow say that the birds’ brightly coloured beaks are an indicator of health. Jonathan Blount, a biologist, and his colleagues think they have found proof that bright red or orange beaks attract females because they mean that the males are healthier. Nothing in nature is simple, however, because in species such as the blue footed booby, a completely different colour seems to give the male birds the same advantage with females.
Meanwhile, what about those athletes who win in their events while wearing red? Do their clothes give them an unintentional advantage? Robert Barton accepts that “that is the implication” of their findings. Is it time for sports authorities to consider new regulations on sports clothing?

| B．red should be the choice of colour for clothing in sports |
| C．red plays a role when competitors are equally capable |
