4 . 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. |
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.
1. What is the text mainly about?| A．The characters of 80s pop music. | B．What made 80s pop music popular. |

| A．80s pop music is and will remain popular | B．80s pop music has many faults |
| C．80s pop music is now out of date | D．we shouldn’t forget the great musicians of the 80s |
6 . 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.

7 . 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.

8 . Traffic jams are the horrible dreams of motorists’ lives. If you think your journey is bad, spare a thought for drivers in Sao Paolo, Brazil — one evening in May last year, the traffic jams during the rush hour added up to a 344km queue, according to the city's traffic management agency.
This isn't a new problem, of course. During the car boom of the 1960s, city planners had one seemingly obvious solution: build more and wider roads. But the more roads created, the more cars they attracted. So what's the solution? Some cities have adopted easy methods, like banning cars from driving on certain days.
However, ending this horrible dream may need more of a complete rethink. A company, Urban Engines, has a slightly fresher method. "We're providing an online game that offers trip suggestions and prizes to encourage commuter behaviour changes, including changing travel from peak to off-peak times,“ says Shiva Shivakumar, Urban Engines' co-founder and GEO. For the past two-and-a-half years, the company has conducted pilot studies in major cities, including Bangalore and Singapore. In Bangalore, one-in-six people who took part in the trial started travelling off-peak, and in Singapore one-in-eight.
But others think this solution doesn't go far enough—and that we should provide more reasons for putting fewer cars on the road. “The only effective long-term solution is to improve alternative methods—walking, cycling and particularly high-quality public transport,” says Todd Litman of the Victoria Transport Policy Institute in Canada. Road pricing that charges motorists extra if they drive during the rush hour could also be an option. Cities like Singapore, London and Stockholm have successfully used road pricing to control the steel river.
The solution to beating traffic jams in cities, if it comes, will probably take a long time to gain prizes. But if at least some of these new ideas are a success, the days of Sao Paolo's heavy traffic jams may finally become history.

9 . Sleep, considered a luxury by many, is essential for a person’s health and happiness. Researchers have found that inadequate sleep and tiredness increase a person’s risk of developing severe medical conditions, such as obesity, high blood sugar levels, and heart disease. Now, a new study has found that getting enough sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smart watches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worn devices (装置), which track a person’s physical activity, would show a connection between exercise and academic achievement.
While Gross’s data showed no relationship between these two factors (因素), the study found something surprising. As the researchers were analyzing their data, they noticed that there was a straight-line relationship between the average amount of sleep a student got and their results in the course’s 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not enough for students to just head to bed early the night before a test. Instead, it’s the sleep you get during the days when learning is happening that matters most.
The time students went to bed each night was similarly important. Those who went to bed in early hours of the morning performed poorly, even if the total sleep time was the same as a higher- performing student. “When you go to bed matters,” Gross says, “If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn’t everything. ”
Perhaps the most interesting was the huge effect that small differences in sleep patterns had on the students’ grades. The entire course grades for students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who changed their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtimes.
Who knew getting A’s just required some extra ZZZ’s?

| D．A person who has a good night’s sleep the night before an important test. |
10 . Located in the southeast of Canada and with a population of approximately 6 million, Toronto is a big and beautiful city, which has developed from a relatively unknown place over the past half century to the center of culture, trade and communication in Canada.
With its colorful ethnic mix, rich history and breathtaking buildings. Toronto offers non-stop adventures to the tourists. To get a sense of how big, various and magical Toronto is, the best place to start is the CN Tower. From this point, visitors can get a bird's-eye view of the city's amazing scenery and unique geography.
In addition to being an important center of culture, trade and communication in Canada, Toronto is also a major muti-ethnic city. It is the most populous city in Canada and its citizens come from countries around the world and from different kinds of ethnic backgrounds. Every day, in most places of the city, a hundred different languages can be heard on the streets, from Hindi to Greek to French. This, perhaps, explains why former Prime Minister Pierre Trudeau once said that Canada is a mosaic（嵌合体）of cultures and languages rather than a melting pot.
Street signs in Toronto are mostly in English. Weekly and daily newspapers are published in various languages, and the city hosts the successful international film festival each September. It is also home to a popular baseball team the Toronto Blue Jays. Toronto has something for everyone.
Moreover, Toronto has been rated one of the most livable cities in the world by United Nations Human Settlements Programme for many years. At the same time, Toronto is one of the safest, richest cities in the world with the highest standard of living.
