1 . Although Bertha Young was thirty she still had moments like this when she wanted to run instead of walk, to take dancing steps on and off the pavement, to throw something up in the air and catch it again, or to stand still and laugh at —nothing — at nothing, simply.
What can you do if you are thirty and, turning the corner of your own street, you suddenly feel happy — absolutely happy.
Oh, is there no way you can express it without being “drunk and disorderly"? How stupid civilization is! Why should you be given a body if you have to keep it shut up in a case like a rare, rare fiddle (小提琴)?
"No, that about the fiddle is not quite what I mean," she thought, running up the steps and feeling in her bag for the key—she'd forgotten it, as usual—and rattling the letter-box. "It's not what I mean, because—Thank you, Mary"— she went into the hall. “Is nurse back?”
“Yes, M’m."
"I'll go upstairs." And she ran upstairs to the nursery.
Nurse sat at a low table giving Little B her supper after her bath. The baby looked up when she saw her mother and began to jump.
“Now, my lovey, eat it up like a good girl," said nurse, setting her lips in a way that Bertha knew, and that meant she had come into the nursery at another wrong moment.
“Has she been good, Nanny?”
“She's been a little sweet all the afternoon," whispered Nanny. "We went to the park and I sat down on a chair and took her out of the pram(婴儿车) and a big dog came along and she pulled its ear. Oh, you should have seen her."
Bertha wanted to ask if it wasn't rather dangerous to let her pull a strange dog's ear. But she did not dare to. She stood watching them, her hands by her side. like the poor little girl in front of the rich girl with the doll.
The baby looked up at her again, stared, and then smiled so charmingly that Bertha couldn't help crying.
“Oh, Nanny, do let me finish giving her supper while you put the bath things away.
“Well, M’m, she oughtn't to be changed hands while she's eating,” said Nanny, still whispering. “It unsettles her, it's very likely to upset her.”
How absurd it was. Why have a baby if it has to be kept—not in a case like a rare, rare fiddle—but in another woman's arms?”
“Oh, I must!” said she.
Very offended, Nanny handed her over.
Now, don't excite her after her supper. You know you do, M'm. And I have such a time with her after!"
Thank heaven! Nanny went out of the room with the bath towels.
"Now I've got you to myself, my little precious," said Bertha, as the baby learned against her.
She ate delightfully, holding up her lips for the spoon and then waving her hands. Sometimes she wouldn't let the spoon go; and sometimes just as Bertha had filled it, she waved it away to the four winds.
When the soup was finished Bertha turned round to the fire. "You're nice—you're very nice!" said she, kissing her warm baby. "I'm fond of you. I like you."
And indeed, she loved Little B so much—her neck as she bent forward, her pretty toes as they shone transparent in the firelight that all her feeling of happiness came back again, and again she didn't know how to express it—what to do with it.
“You’re wanted on the telephone," said Nanny, coming back in victory and seizing her Little B.

2 . Imagine a world where you move around in front of a personal computer in your own sound space. You listen to your favorite songs, play loud computer games or watch a movie — all without other people hearing the sound and without headphones.
That is the possibility presented by “sound beaming”, a new technology from Noveto Systems, an Israeli company. On Friday, the company introduced 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 SoundBeamer 1.0 before its introduction. 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. Because the device does not use headphones, it is possible to hear other sounds in the room clearly.
The device uses a 3-D sensing module that finds and follows the ear position of the listener. It sends ultrasonic waves (超声波) to create sound pockets by the user’s ears. The 3-D method creates sound on all sides of the listener, therefore the listeners feel completely transported into the scene.
By changing a setting, the sound can follow a listener around when he moves his 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.
According to the chief executive officer Christophe Ramstein, a “smaller” version of the device will be ready for release to consumers next year.

3 . 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.

| C．Starman is likely reduced to at most its frame and glass. |
| D．SpaceX will try to recover it during its next space mission. |
4 . New research suggests that dogs might be able to help save diseased citrus trees.
A group of scientists trained dogs to use their sense of smell to detect a crop disease called citrus-greening. The disease has affected orange, lemon and grapefruit trees in the American states of Florida, California and Texas.
The dogs can detect the disease weeks to years before it appears on tree leaves and roots, the researchers report. A study on their findings was published recently in the Proceedings of the National Academy of Sciences. The report says using dogs is also faster, less costly and more exact than having people collect hundreds of leaves for lab analysis.
Timothy Gottwald is a researcher with the U. S. Department of Agriculture and a co-writer of the study. He told The Associated Press, “This technology is thousands of years old-the dog’s nose. We’ve just trained dogs to hunt new prey.”
Citrus-greening is caused by a bacteria (细菌) that is spread by a tiny insect that feeds on the leaves and stems of citrus trees. Once a tree is infected (感染), there is no cure. The disease has also hurt citrus crops in Central and South America and Asia. In one experiment involving grapefruit trees in Texas, trained dogs were correct 95 percent of the time in telling the difference between newly infected trees and healthy ones. “The earlier you detect a disease, the better chance you have at stopping an epidemic (流行病) by removing infected trees,” Gottwald said.
Matteo Garbelotto studies plants at the University of California, Berkeley. He says the new research shows that dogs can detect an infection well before current methods. Garbelotto has been involved in similar research but had no part in the new study.
Laura Sims is a plant scientist with Louisiana Tech University. She praised the steps taken to find out if the dogs were detecting the bacteria itself or a plant’s reaction to an infection. To do that, the researchers infected different kinds of unrelated plants with the bacteria in a laboratory. The dogs were still able to pick out the infected plants.
Gottwald said, “You’ve seen dogs working in airports, detecting drugs and explosives. Maybe soon you will see them working on more farms. ”

5 . 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. |

6 . Social Networking Sites: Are They Changing Human Communication?
It is hardly news that people are using the Internet to communicate with others more and more. Some people fear that someday we will no longer feel the need to talk to one another face to face. However, some recent studies suggest that people communicate, or stay in touch, even more than they used to. Whichever side you fall on, what is clear and without a doubt is that human communication has changed in the 21st century. But results of recent scientific studies may have us reconsider just how much our new communication forms have changed our world.
In June 2008, a British psychiatrist, Himanshu Tyagi, warned that communicating on social networking sites could have a negative effect on the generation of people born after 1990. This generation has never known a world without the Internet. Tyagi says that these people use the Internet to communicate with others so much that they may have trouble forming real relationships. Tyagi is concerned that people may start and end relationships over the Internet. Describing the Internet he said, “It’s a world where everything moves fast and changes all the time, where relationships are quickly ended at the click of a mouse.”
Another psychologist, Dr. Aric Sigman, warned of the physical effects that come with using social networking sites. He suggests that the reduction in the amount of time we spend interacting (互动交流) with people face to face could have biological effects on the human body. The results of his study suggest that, without real personal interaction, the body does not react the same way it would if people were meeting face to face. As a result, immune responses, even hormone levels, can be changed. These changes may lead to the development of illnesses, such as cancer.
Despite these warnings, studies can be found that show the positive sides of social networking sites. The results of one study show that using social networking sites has increased the self-esteem (自尊心) of young adults. Another suggests that college students using these sites feel more “connected” with people when they use them. In addition to scientific studies, there are many who feel that the benefits of social networking sites outweigh the possible negative sides. Many people, especially those who spend a lot of time at home, for various reasons, find the Internet a lifeline. They are able to communicate with many people using these sites.
Perhaps the key to this new communication style is self-control and common sense. If someone spends all of his time on the Internet, and never actually sees friends face to face, that seems like an unhealthy way to live. But if someone spends time on the Internet, some of which is spent arranging meetings for “real” time together, then it seems almost complementary (互补的). Balance is the key to keeping communication alive and well in the 21st century.
1. Which of the following ideas may Himanshu Tyagi agree with?| A．Social networking sites harm people of all ages. |
| B．The Internet weakens young people’s relationships. |
| C．The use of the Internet improves people’s immune system. |
| D．The online world pushes people to live a faster and better life. |
| A．It will stop the face-to-face interaction. |
| B．It reduces the self-esteem of young adults. |
| C．It may cause some serious health problems. |
| D．It makes people feel less connected with others. |
| A．Are greater than. | B．Are heavier than. |
| C．Are more effective than. | D．Are more difficult than. |

7 . Elizabeth Spelke, a cognitive (认知的) psychologist at Harvard, has spent her career testing the world's most complex learning system-the mind of a baby. Babies might seem like no match for artificial intelligence (AI). They are terrible at labeling images, hopeless at mining text, and awful at video games. Then again, babies can do things beyond the reach of any AI. By just a few months old, they’ve begun to grasp the foundations of language, such as grammar. They’ve started to understand how to adapt to unfamiliar situations.
Yet even experts like Spelke don’t understand precisely how babies — or adults, for that matter — learn. That gap points to a puzzle at the heart of modern artificial intelligence: We're not sure what to aim for.
Consider one of the most impressive examples of AI, Alpha Zero, a programme that plays board games with superhuman skill. After playing thousands of games against itself at a super speed, and learning from winning positions, Alpha Zero independently discovered several famous chess strategies and even invented new ones. It certainly seems like a machine eclipsing human cognitive abilities. But Alpha Zero needs to play millions more games than a person during practice to learn a game. Most importantly, it cannot take what it has learned from the game and apply it to another area.
To some AI experts, that calls for a new approach. In a November research paper, Francois Chollet, a well-known AI engineer, argued that it’s misguided to measure machine intelligence just according to its skills at specific tasks. “Humans don’t start out with skills; they start out with a broad ability to acquire new skills,” he says. “What a strong human chess player is demonstrating is not only the ability to play chess, but the potential to fulfill any task of a similar difficulty.” Chollet posed a set of problems, each of which requires an AI programme to arrange colored squares on a grid (格栅) based on just a few prior examples. It’s not hard for a person. But modern machine-learning programmes-trained on huge amounts of data — cannot learn from so few examples.
Josh Tenenbaum, a professor in MIT's Center for Brains, Minds & Machines, works closely with Spelke and uses insights from cognitive science as inspiration for his programmes. He says much of modern AI misses the bigger picture, comparing it to a cartoon about a two-dimensional world populated by simple geometrical (几何形的) people. AI programmes will need to learn in new ways — for example, by drawing causal inferences rather than simply finding patterns. “At some point — you know, if you’re intelligent — you realize maybe there's something else out there,” he says.

8 . Many people with autism (自闭症) have trouble making eye contact, reading the emotions in other faces, and sharing affection. And no drugs are approved to treat such social impairments. Now, results from a Stanford University study suggest increasing levels of vasopressin (加压素) -a hormone (荷尔蒙) active in the brain known to promote bonding in many animals-can improve social deficits in children with autism.
Recently, Karen Parker, a scientist at Stanford University, and her colleagues have turned up evidence that monkeys that were less social had lower levels of vasopressin. The group also found children with autism who had the most social impairment had the lowest vasopressin levels.
The Stanford team gave a nasal (鼻的) spray containing vasopressin to 17 children with autism, aged 6 to 12 years. Another 13 children with autism served as a control group and got a placebo (无效对照的) spray, before and after the 4-week treatment, the research team asked parents to rate the children on a questionnaire called the Social Responsiveness Scale (SRS-2), which asks, for example, how often the children "would rather be alone than with others."
It turned out that vasopressin-treated children showed significantly more improvement-a seven-point-greater reduction-on the SRS-2 than those in the placebo group, the team reported in Science Translational Medicine. Those results "are very exciting," especially because the team didn't see major side effects, says Angela Sirigu, who is also investigating hormones for autism treatment.
Children with higher levels of vasopressin at the start of the study saw greater improvements. That's unexpected, Sirigu says—you'd expect children who were the most deficient in the hormone to benefit the most from the increase. Or maybe vasopressin is a marker for some other, yet-unknown feature of the children that predicts how much they'll improve with the treatment
The only weakness Pelphrey found with the Stanford study was its sample size: "if it were double, I would be jumping up and down." Still, he says, "I'm kind of rocking back and forth in my chair with excitement."

| D．Increase vasopressin in adults with autism to see its influence. |
9 . The coronavirus has been a catalyst for change in many areas of our lives. As things return to normal, one thing that is likely to remain for many is the practice of working from home, known as telecommuting.
Much like the cloud classroom, the cloud office enables employees to cooperate, access resources and operate software from any location. Without doubt, communication tools play an important role. Video and voice chat allow a team, regardless of location, to work together as if they're in the same office.
The rise of telecommuting is due in part to time-tracking applications and software that allows employers to monitor productivity. Wechat Work and Work Examiner are all popular options that have been adopted by thousands of companies. These tools make employers feel secure that remote workers are staying on task. As an increasingly popular approach to work, the objective of the cloud office is to find the ideal balance between home and office work.
According to CNBC, a study showed that 85 percent of millennials（千禧一代）preferred working from home as it gives them a healthier work-life balance, flexible hours and more autonomy. It also showed that firms could save $ 11,000per person each year by allowing employees to work from home.
However, not everyone sees this revolution as positive. According to Bloomberg, in a survey of 1,001 US workers, 45 percent felt burnt out due to the increased workload, decreased communication and the requirement to juggle（兼顾）professional and personal life.
There has indeed been a mixed reaction to the move amid the pandemic.
It's believed that it will become more manageable once lockdown measures are fully lifted worldwide. And by then, who knows what tasks we could all achieve from the comfort of our sofas?
1. Which of the following is closest in meaning to the underlined word in the first paragraph?| A．disaster. | B．motivation. |
| C．cause. | D．disease. |
| A．Employers hold different opinions towards telecommuting. |
| B．The purpose of working from home is to help achieve work-life balance. |
| C．Working from home can help employers spend less on human resources. |
| D．Software that enables workers to monitor work gains increasing popularity. |
| A．Positive. | B．Negative. |
| C．Neutral. | D．Unclear. |
10 . The concept of ownership comes so easily to humans that even preschoolers have got it. Robots, on the other hand, often struggle to grasp such abstract concepts. Now a well-mannered robot that can make it has been programmed.
“Teaching robots ownership-related etiquette (礼仪) is really, really worthwhile,” says Matthias Scheutz, a computer scientist at Tufts University. "We can't just send out robots who are unaware of who owns what... If I instruct a robot to ‘build a fence’, and it goes to the neighbor’s and starts ‘stealing’ boards, that's not what we have in mind.”
The new socially conscious robot can learn who owns what from clear statements as well as its own observations. The robot learns its code of conduct (行为准则) from direct orders and generalizing from specific examples. For instance, if the robot is told not to touch several objects that it knows belong to specific people, the robot will deduce that, as a general rule, it shouldn’t touch owned objects.
Artificial intelligence (AI) expert Xuan Tan and colleagues at Yale found out how the robot reacts in experiments with blocks on a table. In one session, Tan played with only the red blocks, leading the robot to infer that these blocks belonged to the same person. When Tan instructed the robot to throw away everything on the table and the machine reached for a red block, Tan stopped the robot, saying, “That's mine.” Now aware that it should not throw Tan’s belongings, and assuming that the rest of the red blocks belonged to Tan as well, the robot cleared the table of everything but red blocks.
Later, when Tan's colleague Jake Brawer directed the robot to throw out a red block, the robot replied, "Sorry, I'm forbidden to throw it away if it's owned by Tan.” Though robots may have more difficulty understanding who owns what in situations filled with far more objects of much wider variety than blocks on a table. Scheutz called it a good "first attempt” at equipping robots with an appreciation of ownership.
1. What does the second paragraph focus on?| A．The way of teaching robots ownership. | B．The basics of the human-robot relationship. |
| C．The benefit of robots learning ownership. | D．The importance of robots learning code of conduct. |
