1 . 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.

2 . 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.

3 . It’s easy to assume that a vacation to Bali will cost a small fortune. There are plenty of accommodations, food and local transportation, and even the spas offer massages and treatments at value prices. However, you can easily spend a week or two in Bali for under $2,000, without having to sleep on the beach. Here are a few things to consider when planning Bali on a budget.
What is the best time to visit Bali on a budget?
If you’re on a budget, consider visiting Bali during the lower, wetter season, which runs from October through March. The crowds will be fewer, and both hotel rates and flights from abroad are often cheaper, except during the holiday period between mid-December and early January, when crowds swell. The only trade-off for the lower prices is the wet season. This time of year isn’t always ideal for sunbathing, and serious rainfall can make outdoor activities, such as whitewater rafting and visiting waterfalls and rice terraces, less than appealing. That said, even during rainy season, it doesn’t usually rain all day long. Expect bursts of sunshine between the storms.
What is the cheapest way to get around Bali?
The absolute cheapest way to get around Bali is by local bus, but it can take a long time. There are also tourist buses, including hop-on, hop-off options, that travel between different hubs across the island. Bali is well-served by taxis, both of the car and motorbike variety, and the prices tend to be affordable by international standards. Most drivers will offer you a fixed rate for full-day hires or to get from point A to point B, rather than using a meter.
Remember to bargain; doing so is particularly easy when a driver is on his own rather than at a taxi stand.
How much does food cost in Bali?
If you’re into fine dining, you can end up spending a large chunk of your budget on food. Eating at the average restaurant geared towards tourists is the best way to have a meal in Bali on a budget. A good meal should cost you around 100,000 rupiah (around $7), but if you’re willing to subsist mostly off of local specialties such as nasi goreng (fried rice) and eat at local restaurants, you can expect to pay around 30,000 rupiah ($2) to get fed. Best of all, most hotels and guesthouses in Bali come with free breakfast, and many offer heavier options of noodles and meat that may keep you full until lunch.
1. Which of the following situation can be best described by the underlined word trade-off in paragraph 2?| A．Jack got a reward after he returned the lost bag to its owner. |
| B．Lily spent much money buying some handicrafts at the local fair. |
| C．Wendy cancelled her trip in order to prevent the spread of the virus. |
| D．Sam was scolded by his parents for what he did in school last night. |
| A．It’s better for outdoor enthusiasts to visit Bali during the off season. |
| B．Passengers had better fix the price with drivers before the taxi pulls out from the station. |
| C．If on a tight budget, one is advised to visit Bali at the end of December every year. |
| D．It’s relatively economical to eat merely at average restaurants tailored to visitors. |
| A．City and Transport. | B．Travel and Recreation. |
| C．Nature and Environment. | D．Food and Health. |
4 . Watson entered Mr Smith's office. The boss was a hard man. He fired people who didn't do well without giving them a second chance.
“Watson,” said Mr Smith, “this past year your department hasn't earned money. We're going to drop that department. It's finished. I'm sorry—but you'll have to go.” “But, sir—if I just had a little more time. For the moment I need the job to keep my son at Riverside School.”
“What's that!” said the boss. “Riverside! I didn't know you had a boy there. That's an expensive school for a man with your salary.”
“I know, sir. But he likes it so much! He's a star athlete and the best boxer in the school. The boys call him Champ there.”
The boss sat perfectly still for a long time—a faraway look in his eyes. Then, suddenly, he said, “We've got to close your department, Watson. But you'll take over a new job in another department. It means longer hours—maybe more pay. Now get out. You're here for life.”
Watson got out, with surprise on his face. Then the boss took a letter from the top drawer of his desk. It was Herbie's last letter from Riverside School—written a few days before he died. He had read it over and over again with sick pain. The letter read:
I can't say the boys here are any nicer to me than the others were. I guess it's the same everywhere when you're a cripple. But don't worry about me, Dad. They've got a good chemistry department here. And there's one boy here who is really great. He's a track star and boxing champ and just tops in chemistry.
The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big—that he won't even know about.
Your son,
Herbie

5 . When I was a kid, my sister and I would fight all the time over nearly everything. But as we grew older, our bond strengthened by sharing secrets, offering advice and trading clothes. Having a sister by my side while growing up taught me many lessons about the unique bond.
And now, thanks to an 8-year long study that’s making the rounds on the Internet again, science is confirming what I know is true. In the study, researchers discovered that having an older or younger sister can help ease the anxiety for kids between the ages of 10 and 14 years. They also found that people with sisters can “learn how to make up and to have control over their emotions again, which are skills that undoubtedly serve children well.
The revival of this study actually comes on the heels of another newer study, which shows that it’s not just the older kids and parents who influence and shape children as they grow. It turns out that younger siblings(兄弟姐妹) do too, and what’s more, they may also give their older siblings a greater chance of developing empathy (同情).
The Canadian study followed 452 pairs of siblings, all between a year-and-a-half and 4 years old. The researchers found that having a younger sibling increased the older sibling's level of empathy.
This research confirms that sisters are pretty amazing in making the world a much lovely place. As the mom of two boys, I often wonder what kinds of lessons they will learn from their younger sister. Perhaps they will be the same lessons I learned from mine that cooler heads always win. This study gives me hope that all those endless arguments between my kids may actually be laying the groundwork for conflict-settlement skills.
1. What can we learn from the study?| A．Children under four develop empathy fastest. |
| B．It is normal for siblings to quarrel. |

| D．Children having siblings are considerate. |
6 . Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.
Researchers at the University of New South Wales, Australia, have invented a soft skin stretch device (SSD), a haptic device that can recreate the sense of touch. Haptic technology can mimic the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.
Vibration is the most common haptic technology today and has been built into many electronic devices, such as one attached to the back of a trackpad in laptops. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely.
The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through soft, artificial “muscles”.
It works like this: imagine you call a friend in Australia. You wear a haptic glove with the SSDs and your friend also wears a glove with 3D force sensors. If your friend picks up an object, it will physically press against your friend’s fingers. And the glove with 3D force sensors will measure these interactions. The force signals can be sent to your glove so your device will generate the same 3D forces, making you experience the same sense of touch as your friend.
The haptic devices could be used in various fields, allowing users to feel objects inside a virtual world or at a distance. This could be especially beneficial during such times like the COVID-19 pandemic when people rely on video calls to stay connected with loved ones. Or it could be used in medical practices. Doctors can feel a patient’s organ tissues without touching them.

7 . Among the four skills in learning English, which one of these is the “odd-man-out”? The answer is speaking. The other three you can do alone on your own. But you can’t really speak alone! Speaking to yourself can be “dangerous” because men in white coats may come and take you away!
Where can you find people to speak English? And how can you practice speaking when you are alone?
At school—If you pay to go to a language school, you should use the opportunity to speak. If your teacher asks you to speak in pairs or groups with other students, try to say as much as possible. Don’t worry about your mistakes. Just speak!
Conversation Clubs—Many cities around the world have conversation clubs where people can exchange one language for another. Look in your local newspaper to find a conversation club near you. They are usually free although some may charge a small entrance fee.
Shopping—Even if you don’t want to buy anything, you can ask questions about products that interest you in a shop. “How much does this cost? ” “Can I pay by cheque? ” Often you can start a real conversation—and it costs you nothing!
Café and Bars—There are often American, Britain, Irish and Australian bars in many large cities. If you can find one, you’ll probably meet many people speaking English as a first or second language.
Language is all around you— Everywhere you go, you find language. Shop names, street names, advertisements, notices, and car numbers.... When you walk down the street, practice reading the words and numbers that you see. Say them to yourself. It’s not exactly a conversation, but it will help you to “think” in English. But don’t speak too loud!
Songs and Videos—Repeat the words of an English song singing with the music until it becomes automatic. It’s good practice for your memory and for the mouth muscles that you need for English.
Above all, speak as much as possible! Make as many mistakes as possible! When you know that you have made a mistake, you know that you have made progress!
1. What does the underlined part “odd-man-out” probably mean according to the passage?| A．Someone or something that can be easily mistaken for another. |
| B．Someone or something appearing different from the others. |
| C．Someone or something standing out of the group. |
| D．Someone or something arranged in pairs. |
| A．Because everyone will make mistakes in learning English. |
| B．Because making mistakes is a must in making progress in learning English. |
| C．Because everyone will meet people speaking English with some mistakes. |
| D．Because making mistakes can make one realize the importance of speaking. |
| A．To tell us that English is all around us. |
| B．To tell us that we can speak English alone. |
| C．To give us some advice on how to practice speaking English. |
| D．To tell us speaking is the easiest of the four skills in learning English. |
8 . Ever wonder how your brain works when making decisions bigger than medium versus spicy salsa, like buying a car or accepting a job offer? Researchers from the University of Dundee in Scotland conducted a study that clarifies why you may want to have a small bite before making that big decision.
Benjamin Vincent from the University of Dundee’s Psychology department and his co-author Jordan Skyrnka tested 50 people two times: once when they followed their normal eating patterns and once when they did not eat anything during the day. Using three different types of rewards (food, money, and song downloads), the team discovered when presented with the choice of receiving the reward now versus double the award at some point in the future, participants would usually volunteer to wait for 35 days to earn a larger bounty, but when they were hungry, they said they would only wait three days.
“We wanted to know whether being in a state of hunger had a specific effect on how you make decisions only relating to food or if it had broader effects, and this research suggests decision-making gets more present-focused when people are hungry,” Vincent said in a story about the study on the university’s website. “You would predict that hunger would impact people’s preferences relating to food, but it is not yet clear why people get more present-focused for completely unrelated rewards. Hunger is so common that it is important to understand the non-obvious ways in which our preferences and decisions may be affected by it,” he said.
In an earlier study of the subject by a team at Cambridge University in England, the researchers noted that serotonin plays a major role in the decision-making process. “Since the raw material for making serotonin—an amino acid called tryptophan — only comes from diet, levels of the chemical decline between meals,” reports a piece in the Telegraph about the study. “This can lead to aggressiveness and impulsiveness,” say the team.
1. How did Benjamin Vincent and Jordan Skyrnka carry out their research?| A．By analyzing reasons. | B．By making comparison. |
| C．By giving examples. | D．By filling questionnaires. |
| A．bonus. | B．quantity. | C．income. | D．fortune. |
| A．It’s common to make a wrong decision if you are hungry. |
| B．Make sure you are not hungry before making a big decision. |
| C．The more hungry you are, the quicker you will make a decision. |
| D．Being hungry drives you to make a decision connected with food. |
| A．What should be eaten to make a wise man. |
| B．How can we get enough serotonin from our diet. |
| C．What other factors will influence one’s decision-making. |
| D．How does a chemical function in the course of making a decision. |
9 . There is an old saying in Chinese: “To do a good job, one must first sharpen one’s tools.” When it comes to photography, however, it’s not exactly the case. In this year’s National Geographic Travel Photo Contest, Greenlandic Winter, a picture by Chinese photographer Chu Weimin, took first place in the cities category and won the overall grand prize as well.
When asked why he chose Upernavik, a small fishing village in Greenland, to take his pictures, Chu described the first time he spotted the village from an airplane. “Through my entire flight, I could only see the land, covered by pure white ice and snow. But I suddenly saw a big, warm dot in the far distance — Upernavik,” he told National Geographic. “The beauty of this tranquil (宁静的) village was beyond my imagination. It was a ‘wow’ moment for me.” This ability to identify a “wow moment” is what makes a good travel photographer.
According to Chu, he was moved by Upernavik’s blue tint at dusk, the warm yellow light from the windows, and the family of three walking along the snowy street. Although he is a professional photographer, many of Chu’s Greenland pictures were shot with his phone.
This attitude echoes that of Austrian-American photographer Ernest Haas (1921-1986). Haas told his students that they were too obsessed with cameras to understand the essence of photography. “The camera doesn’t make a bit of difference,” Haas said. “All of them can record what you are seeing. But you have to SEE.”
Perhaps it’s not just in photography that we’ve put too much emphasis on the role of tools. How many of you are reluctant to start a new sport or learn new software simply because you don’t yet have the “right” outfit (装备) or computer?
It’s true that “sharpened” tools make the work easier, hut as reporter Abhilash Pavuluri wrote on Firstpost: “In the end, it’s really the artist that makes a good painting, not the paintbrush.”
1. What do we know about Chu Weimin?| A．He is better at photographing people than scenery. |

10 . A year ago, I paid no attention to English idioms, though my teacher emphasized the importance again and again. But soon, the importance of English idioms was shown in an amusing experience.
One day, I happened to meet an Englishman on the road, and soon we began to talk. As I was talking about how I was studying English, the foreigner seemed to be astonished, gently shaking his head, shrugging his shoulders, saying, “You don’t say! ” “You don’t say! ” I was puzzled. I thought, “Perhaps this is not an appropriate topic. Well, I’d better change the topic. ” So I said to him, “Well, shall we talk about the Great Wall? By the way, have you ever been there? ”“Certainly, everyone back home will laugh at me if I leave China without seeing it. It is magnificent. ” He was deep in thought when I began to talk like a tourist guide, “The Great Wall is one of the wonders in the world. We are very proud of it. ” Soon I was interrupted again by his order, “You don’t say! ” I couldn’t help asking. I said, “Didn’t you say you don’t say? ” Hearing this, the Englishman laughed. He explained, “ ‘You don’t say’ actually means ‘Really? ’. It is an expression of surprise. Perhaps you haven’t learned that English idiom. ” Only then did I realize I had made a fool of myself. Since then, I have been more careful with idiomatic expressions.
