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.
1. What can we infer from the first two paragraphs?| A．Starman is now circling around the Earth in its orbit. |

| C．By seeking professional help from SpaceX. |
| D．By analyzing data about the rocket’s movement. |
| A．pull | B．drive | C．resistance | D．pressure |
| A．It is circling around Mars and will finally crash onto it. |
| B．It will finish its mission and return to SpaceX on earth. |
| C．Starman is likely reduced to at most its frame and glass. |
| D．SpaceX will try to recover it during its next space mission. |
3 . 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. |
| A．most miserable. | B．most cheerful. | C．most generous. | D．most glorious. |
| A．Building confidence. | B．Developing exam skills. |
| C．Learning self-control. | D．Gaining biomedical knowledge. |
| A．A biomedical library cleaner. . | B．A group of warm-hearted students. |
| C．Money-raising to send a cleaner on vacation. | D．The most loved cleaning staff. |
4 . 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?
1. According to their research, Hill and Barton conclude that _____.| A．the colour of clothing has an effect on most sport events |
| B．red should be the choice of colour for clothing in sports |
| C．red plays a role when competitors are equally capable |

| C．Need to Change the Rules in Sports? | D．Red Is for Winners. |
5 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
1. What is the recent study mainly about?| A．Food safety. | B．Movie viewership. |

6 . When you were trying to figure out what to buy for the environmentalist on your holiday list, fur probably didn’t cross your mind. But some ecologists and fashion (时装)enthusiasts are trying to bring back the market for fur made from nutria(海狸鼠).
Unusual fashion shows in New Orleans and Brooklyn have showcased nutria fur made into clothes in different styles. “It sounds crazy to talk about guilt-free fur-unless you understand that the nutria are destroying vast wetlands every year”, says Cree McCree, project director of Righteous Fur.
Scientists in Louisiana were so concerned that they decided to pay hunters $5 a tail. Some of the fur ends up in the fashion shows like the one in Brooklyn last month.
Nutria were brought there from Argentina by fur farmers and let go into the wild. “The ecosystem down there can’t handle this non-native species(物种).It’s destroying the environment. It’s them or us.” says Michael Massimi, an expert in this field.
The fur trade kept nutria in check for decades，but when the market for nutria collapsed in the late 1980s，the cat-sized animals multiplied like crazy.
Biologist Edmond Mouton runs the nutria control program for Louisiana. He says it’s not easy to convince people that nutria fur is green, but he has no doubt about it. Hunters bring in more than 300,000 nutria tails a year, so part of Mouton’s job these days is trying to promote fur.
Then there’s Righteous Fur and its unusual fashion. Model Paige Morgan says，”To give people a guilt-free option that they can wear without someone throwing paint on them-I think that’s going to be a massive thing, at least here in New York.” Designer Jennifer Anderson admits it took her a while to come around to the opinion that using nutria fur for her creations is morally acceptable. She is trying to come up with a label to attach to nutria fashions to show it is eco-friendly.

| A．It’s formal. | B．It’s risky. | C．It’s harmful. | D．It’s traditional. |
7 . In 2012, James Cameron, creator of Avatar and Titanic, became the first person to reach the Challenger Deep. When he arrived at the deepest spot on Earth at 7 miles below sea level, he spent hours mapping the region and taking photos and samples.
“As human beings, we’re drawn to absolutes—the deepest, the highest, the coldest, the farthest,” he says. “And as a storyteller and curious monkey, I just wanted to see what was there.” The answer is obvious—plastic and more. “Our so-called civilization is using the ocean as its toilet,” Cameron says. “Unless this changes, ocean ecosystems are going to continue their rapid collapse.”
Despite decades of environmental studies, the impact of plastic and other forms of pollution on oceans are not entirely understood. Initial studies appear to indicate that ingesting(摄取) them—either directly or indirectly—could cause disease. Plastics can also release poisonous substances into the water, which could potentially impact animal populations.
But plastic is just one of the problems facing oceans that have yet to be fully understood. “Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which include carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic(缺氧的) dead zones the size of countries,” Cameron says.
Oceans, like the rest of the world, are impacted by the burning of fossil fuels and the release of greenhouse gases like carbon dioxide—about 30 percent of which is absorbed by the sea. This absorption causes ocean acidification, where the pH level is altered to become more acidic. As a result, it’s harder for some creatures to form shells and skeletons and countless species at the base of the food web can struggle to survive, which, scientists say, has the potential to cause huge disruptions to entire ecosystems. Indeed, ocean acidification is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.
The effect of climate change on the world’s oceans will likely worsen in coming decades. Last June, scientists announced carbon dioxide levels had reached the highest levels since human records began. The last time carbon dioxide levels were this high was during the Pliocene era, between 3 and 5 million years ago, when global temperatures were about 4 degrees Celsius warmer than they are today. Current climate models suggest that if greenhouse gas emissions continue on their current trend, we may be on course to see 4 degrees of warming by 2100.
As a result, understanding the role oceans have on global systems is becoming more and more important.

9 . Traveling with kids is 90 percent reminding yourself to live in the moment and 10 percent making up your mind to never again leave your house.
I have an uncanny ability to forget this as soon as we return home from a trip and I've finished washing piles of dirty clothes in our luggage and cleaning all the messy caused by the kids. Extremely tired and annoyed, I would actually begin to miss the place we just left!
Family travel is like childbirth, I suppose. Painful, loud, messy, sort of awful, actually, but also wonderful. And you remember only the wonderful—until you’re back on a plane and your kids are fighting over who gets the aisle seat. Then you remember the bad stuff.
Last weekend, my kids and I flew to Texas for a trip we would have nothing to complain(抱怨) about—big hotel, wonderful view.
And yet—we found things to complain about. The pool was bigger in that other hotel! Why do you get to shower first? They call this coffee?! Luckily, I’ve learned to put my metaphorical coat of armor (盔甲) on as soon as we land somewhere, and it forces complaints to bounce off me and land in a pile at my feet.
For three days, genuine fun was had and annoying complaints were heard and ignored. Until it was time to catch a plane and fly home.
Unfortunately, our flight was canceled. We spent hours finding a hotel room. We hit the hotel pool before bed and swam well into the night, my kids making up songs and laughing so hard at their silly lyrics (歌词) and their crazy good fortune to be swimming at 10: 30 on a school night.
And that was when it hit me that family travel is all those things I said before but it’s also a lot more. It’s taking your kids to parts of the world that will open their eyes and finding that actually, yours need opening too. It’s remembering that joy and memories are where you make them, not where you find them.

10 . When photographer Simon Czapp took pictures of a curious five-month-old fox, he soon realized this little fox was attracted by his subject. The clever fox was so curious about the camera equipment that she climbed on top of it. And while she was supposed to be the subject of the shoot, the fox stood on the shutter release button (快门按钮) and took her own frames.
Mr. Czapp visited the New Forest Wildlife Park to capture images of new arrival Jessie. Jessie is a lovely little fox. She has been at the animal park in Ashurst, Hampshire—home to wolves, deer and others in 25 acres of ancient woodland after being abandoned by her mother.
Mr. Czapp said, “Jessie was very playful and curious and not shy at all in front of the camera. Soon after I arrived she was chewing my shoes and everything seemed to be a game to her. Then she started exploring the camera I had set up on a tripod (三脚架). She stood on her back legs to look at the back of the camera. She balanced her front paws on it and at one point knocked it over. ”
He put the camera back on the tripod and Jessie soon jumped back up. At one point she had all four paws on the camera and was keeping her balance. Mr. Czapp added, “She jumped up there several times and I realized it could make a good picture. As I was leaving away with the public’s viewing window (取景窗) behind me, I thought I heard the camera go off but didn’t think much of it. However, when I checked the memory card afterwards, I was amazed to see Jessie had actually taken two frames of me photographing her. I couldn’t believe I had been outfoxed (智取) by a fox! There were some lovely photos of her but she obviously thought the photographer was worthy of a picture too! ”
