1 . As data and identity theft becomes more and more common, the market is growing for biometric(生物测量) technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.
Researchers from Georgia Tech say that they have come up with a low-cost device(装置) that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence(节奏) with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.
It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.
In a study describing the technology, the researchers had 100 volunteers type the word “touch” four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

2 . A small bowl bought at a yard sale in Connecticut for just $ 35 has been identified as a rare 15th-century Chinese antique.
The blue-and-white bowl was made by China's royal court during the Ming dynasty. It is now expected to sell for up to $500,000, according to Sotheby's auction(拍卖)house in New York, where the auction will take place next month.
The purchase was made last year near New Haven, Connecticut. “I was just hanging around there aimlessly. But when I saw this bowl, I didn't even bargain over the $35 asking price,” the owner said. Shortly after the purchase, he sent photos of the bowl to auction specialists, who identified it as an item of historical significance.
Upon closer inspection, the artifact was found to have originated from the period of Yongle Emperor, who ruled from 1403 to 1424 - a period noted for its distinctive porcelain (瓷器)techniques. It's now valued between $300,000 and $500,000, with the top estimate nearly 14,300 times the amount it was purchased for.
“I was deeply attracted by the techniques. You can see why this bowl is so highly-valued from the very smooth porcelain body, silky glaze(上釉)and special blue coloring, which were never reproduced in later dynasties,” McAteer, an auction specialist, said.
“The Yongle Emperor improved the porcelain techniques and elevated the importance of porcelain from being an ordinary bowl into a true work of art. This small bowl has both practical and artistic value, ”McAteer said.

3 . It might seem strange to be making predictions about 2021, but one thing is clear: technology has been affected just as much as every other part of our lives. Another clear thing is that today’s most important technology trends will play a big part in helping us deal with and adapt to the many challenges facing us. From the shift to working from home to new rules about how we meet and interact in public spaces, technology trends will be the driving force in managing the change.
One of the major technology trends that are likely to play out this year is 5G and enhanced connectivity. Each successive advance in mobile connectivity from 3G onwards has unlocked new use cases for the Internet. 3G made web browsing and data-driven services useful on mobile devices, 4G led to the growth of streaming video and music platforms as bandwidths (宽带) increased, and 5G, similarly, will open more doors in terms of what is possible.
5G means that services relying on advanced technologies such as augmented (增强的) reality and virtual reality, as well as cloud-based gaming platforms like Google’s Stadia, become a practical thing, anywhere at any time. They also threaten to make cable and fiber-based (光纤) networks redundant, with their need for us to be tied to a particular location.
In short, 5G and other advanced, high-speed networks make other new technologies available anywhere, any time. A great example is Norwegian fishery operator Salmar that uses a 5G network to automate the care and feeding of its fish. Image recognition algorithms (算法) are used to detect which fish are over or under-feeding, and automatically distribute food and medicine needed to keep them healthy. Initiatives like this will become increasingly important during 2021, where businesses look to increase automation across their workforces.
1. Which of the following is highly influenced by 5G technology?| A．Data-driven services. | B．Streaming video. |
| C．Music platforms. | D．Google’s Stadia. |
| A．Useful. | B．Unnecessary. | C．Expensive. | D．Special. |
| A．To show the development of Norwegian fishery. |
| B．To explain how to keep fish healthy. |
| C．To present the application of 5G technology. |
| D．To propose new initiatives for businesses. |
| A．Different predictions of technology trends. |
| B．Successive advances in mobile technology. |
| C．One of the technological highlights of the year. |
| D．The driving force in managing changes. |
4 . It is sometimes jokingly said that you may skip a meal a day without any adverse effect but skip using your WeChat for an hour and you will feel distinctly unwell. It is an acknowledgement of the fact that the app is no longer only a fun tool but an essential part of life for millions.
Launched in January 2011, this messaging, social media and mobile payment app today has more than 1 billion individual users. People use it for everything, from applying for a business license to booking a hospital appointment to keeping up with family and friends, shopping and paying bills—activities that are part and parcel of our everyday life.
When it was first introduced, WeChat was only an app supporting voice, video, picture and text messages between two persons or among a group. But today it has become ubiquitous.
In the past, people carried their wallet and keys with them wherever they went; today, a smart phone with WeChat installed is all they need in daily life. Its functions like Moments and mini programs and the official WeChat accounts of government agencies and companies have made communication and public services accessible and convenient like never before.
WeChat is also widely used by enterprises. Figures from Tencent show there are around 15 million WeChat official accounts, which enjoy 5 billion followers. Most businesses use their WeChat groups as a standard marketing kit. This has immensely reduced advertising, marketing and communication costs, and in the background of the novel coronavirus disease, made operations faster, contactless and safe.
However, there are concerns about the downsides of WeChat, such as addiction among primary school children. Equally serious is the misuse of WeChat for fraud or instigating crimes. However, it has to be kept in mind that these fallouts are not really the fault of WeChat, but due to the misuse of the app.
If we learn to temper our use of messaging apps with prudence and pragmatism, we could be looking forward to yet new conveniences and experience in this decade with the rapid development of 5G technology and artificial intelligence. Ultimately, the choice is ours, whether to use WeChat or any other new invention, wisely or wantonly.

5 . What do you think of 80s pop music? Do the names George Michael, Madonna and Michael Jackson sound familiar? Well, these are just some of the names that were well-known in the music scene of the 80s and early 90s. The 80s pop music scene was an important step to the popularity (普及) of present-day music. A new wave in the music scene was introduced, which made such music styles as punk rock, rap music and the MTV popular. Although it was an end to the old 60s and 70s styles, it was also the beginning of something big. The popularity of music videos meant that artists now replaced their guitar-based music with visual displays. A new wave of artists came on the scene and the entire industry developed quickly.
The most famous 80s pop music video is Michael Jackson’s Thriller. Introduced in 1982, few people can forget the video not only because of its never-be-foreseen images, but also because of the popularity it received. Think of how 80s pop music changed the lives of people who grew up in the 80s. Ask a young man today to tell you the names of the “New Kids on the Block” and he will start talking about the neighbor kids who just moved in. These are not the answers you might have heard in the 80s. Though today’s young men do not recognize how cool 80s pop music was, most people will always remember it for what it was and these are happy memories they will always love.
Some of the 80s pop music legends (传奇人物) include Madonna, U2, AeroSmith and of course the King of Pop Michael Jackson. Let’s not forget Prince, Tina Turner, Phil Collins and Motown’s Lionel Ritchie. Some of these musicians played music that has stood the test of time. Undoubtedly, the 80s pop music scene will live on for many more years to come.

6 . As more and more people speak the global language of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will be likely to die out by the next century, according the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations — UNESCO and National Geographic among them — have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following in that tradition. His recently published book, A Grammar of Thangmi and Their Culture, grows out of his experience living, working, and raising a family in a village in Nepal.
Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials —including photographs, films, tape recordings, and field notes — which had remained unstudied and were badly in need of care and protection. Now, through the two organizations that he has founded — the Digital Himalaya Project and the World Oral Literature Project — Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to schools but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

7 . Emory Jensen, a 10-year-old fourth-grader, ran her fingers across a wall covered in artwork as she walked through an art exhibit. “It’s something that would get me in trouble or kicked out elsewhere,” she said unbelievably.
But Emory, who is unable to see, wasn’t kicked out, because it wasn’t at a typical art museum, but at the fully immersive (沉浸式的) art experience called “dreamscapes” as part of a field trip designed to help expose blind students to art. “We can all just feel it and it’s not what we can only look at,” she continued. “It’s awesome. The experience is like that in Alice in Wonderland.” The student also said she wanted to visit again with her cousin who suffers the same inborn eyesight problem.
“Most of these students probably have never been able to go to an art museum or really get to experience what art is,” said Kate Borg, director of blind campus programs. Art is typically focused on visuals, but “dreamscapes” is aimed at more. Sight, touch and smell are a big part of it, as well as emotional feelings. It uses different sounds, smells and substances (物质) in the artwork and allows people to walk through spaces with different themes.
Some staff were blown away to watch the children experience the art. “I couldn’t hold back my tears,” said Andrea Silva, “dreamscapes” manager. “I’ve never seen a visitor so lost in and curious about the art. We wanted it to be accessible to everyone, including and especially kids.”
Accessibility for art is vital, Borg said. “We read research after research that talks about creativity and art being so important for children in their development and growth,” she said. “And just because a child is blind or visually impaired (受损的) doesn’t mean that they shouldn’t have the same opportunity. They absolutely need to be close to art, and we have to be a little more creative in making sure we provide that.”
1. What can be learned about “dreamscapes”?| A．It is open to the students only. | B．It is focused on various senses. |
| C．It is built with special materials. | D．It is decorated to look like a fantasy world. |
| A．Touched. | B．Curious. | C．Proud. | D．Puzzled. |
| A．The necessity for children to research art. |
| B．The way to get children to think creatively. |
| C．The reason to help blind kids get access to art. |
| D．The importance for blind kids to develop overall. |
8 . Not long ago, Linda Khan was sitting by a hospital bed in Houston, feeling ill at ease. Beside her lay her father who needed a heart surgery. The two of them had engaged in nothing but depressing small talk. Then, her eye fell on a pile of books. She picked up one, and started to read it out loud. "Right away it changed the mood and atmosphere," she says. Reading gave the daughter a way to connect with her father. Listening allowed the father travel on the sound of his daughter's voice into a place where he felt himself again. “From then on," Khan says, “I always read to him."
In a 2010 survey in the United Kingdom, elderly adults who joined weekly read-aloud groups reported better concentration, less anxiety, and an improved ability to socialize. The survey authors owed these improvements in large part to the “rich, varied diet of serious literature" that group members consumed, with fiction encouraging feelings of relaxation and calm, poetry fostering focused concentration, and narratives giving rise to cognitive (认知的) thoughts, feelings, and memories. In truth, almost any kind of reading to another person can be beneficial.
Readers get rewards too. For Neil Bush, the late-life hospitalizations of his famous parents, George H. W. and Barbara Bush, became opportunities to repay a debt of gratitude. “When I was a kid, they would read to me," he said. With his parents in and out of care, “We've been reading books about Dad's foreign policy and, more recently, Mom's autobiography." Bush went on, his voice thick with emotion, “And to read their amazing life to them has been a remarkable blessing to me, personally, as their son."
To many people, reading to parents may seem so far outside the normal range of regular activities, and it may even feel odd and improper. However, there are still a lot many who brave the momentary strangeness of reading to elderly adults and both reader and listeners are, to borrow a phrase from Wordsworth, surprised by the joy of it.
1. What did reading offer to Linda and her father?| A．A way to establish a bond. | B．A way to travel together in reality. |
| C．A way to treat the disease. | D．A way to engage in learning. |
| A．Improvements in mental health. | B．Benefits of reading to others. |
| C．Changes in cognitive process. | D．Development of social skills. |
| A．Reading benefits more than the listener |
| B．Parents should red more to their kids. |
| C．Children should show their gratitude. |
| D．Reading to parents is children's duty |
| A．Improper and odd. | B．Abnormal but worthy. |
| C．Rewarding and joyful. | D．Interesting but unnecessary. |
9 . Who're happier, men or women?Research shows it's a complex question and that asking whether males or females are happier isn't really that helpful, because basically, happiness is different for women and men.
Women's happiness has been declining for the past 30 years, according to recent statistics.And research shows that women are twice as likely to experience depression compared with men.Gender（性别） differences in depression are well confirmed and studies have found that biological, psychological and social factors contribute to the difference.
Early studies on gender and happiness found men and women were socialized to express different feelings.Women are more likely to express happiness, warmth and fear, which help with social bonding and appear more consistent with the traditional role as a primary caregiver, while men display more anger, pride and disrespect, which are more consistent with a protector and provider role.
Recent research suggests that these differences are not just socially, but also genetically related.Studies have looked into these findings further and discovered that females use more areas of the brain containing mirror neurons（镜像神经元）than males when they process feelings.Mirror neurons allow us to experience the world from other people's view, to understand their actions and intentions.This may explain why women can experience deeper sadness.Women tend to experience more negative feelings, such as more guilt, shame and to a lesser degree, embarrassment.
Psychologically it seems men and women differ in the way they process and express feelings.With the exception of anger, women experience feelings more strongly and share their feelings more openly with others.Studies have found in particular that women express more appreciation﹣which has been linked to greater happiness.This supports the theory that women's happiness is more dependent on relationships than men's.
1. Which feeling are men more likely to show compared with women?| A．Warmth. |
| B．Depression. |
| C．Happiness. |
| D．Disrespect. |

| C．Social roles have a great effect on men and women. |
| D．Women's happiness has declined in the past years. |
10 . Norway aims to discover new resources beneath the sea, but its push into mining has raised environmental concerms.
Norway could license companies for deep-sea mining as early as 2023. That could place it among the first countries to harvest seabed metals. Copper, zinc and other metals are in high demand for electric vehicle batteries, wind turbines and solar energy centers. However, that could also place Norway on the front line of controversies over the environmental risks of mining the world’s unexplored seabeds.
Norway recently announced it was carrying out an environmental study needed to start mineral exploration and mining. Once that is completed, the govemment plans to have public comments on its environmental study and on a proposal to open areas for exploration and production by the end of 2022.
The demand for minerals is being driven by what are often called “clean” technologies. But the process of getting those minerals from the seabed could cause environmental problems.
Environmentalists including Britain’s David Attenborough have called for a temporary (暂时的) stop to deepseabed mining until more is known about how it affects sea life. The environmental group Greenpeace called for a total ban in a recent report. In another report, the High Level Panel for a Sustainable Ocean Economy, known as the Ocean Panel, also called for greater knowledge about the effects of deep-sea mining. The Ocean Panel is cochaired by Norway and has 14 member states that want to shape policy on the world’s oceans.
Norway is known as a major oil producer. But, the country of 5. 4 million people wants to find something to replace its top industry that is better for the environment and can grow in the future.
The move toward deep-sea mining follows three years of expeditions(探险). The Norwegian Petroleum Directorate, which carried out the work, said it found copper, zinc, cobalt, gold and silver. The expeditions also discovered large armounts of lithium and the rare earth metal scandium used in electronics and metal mixtures.
1. What does the underlined word “controversies”in paragraph 2 probably mean?| A．Power. | B．Benefits. |
| C．Arguments. | D．Popularity. |
