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.
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. |

| B．Successive advances in mobile technology. |
| C．One of the technological highlights of the year. |
| D．The driving force in managing changes. |
2 . 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. |
3 . Vegetarian foods are not equally healthy, according to a new research at ESC Congress 2020. Dr. Matina said, “This finding was more clear in women. A recent research has shown that women tend to eat more plant-based foods and less animal-based products than men. But our study suggests this does not ensure healthier food choices and in turn better health condition.
Most studies see plant-based diets simply as "vegetarian" or “low in meat”, thus treating all plant foods as equal. However, this study examined the type of plant-based foods eaten, in addition to the overall amount. Healthy plant-based products were made up of fruits, vegetables and coffee while unhealthy plant-based products included juices, potatoes and any kind of sweets.
The study examined the link between the quantity（数量）and quality of plant-based foods and heart health over a 10-year period. In 2011, the study selected 146 fat adults living in Athens with normal blood pressure and blood sugar. Diet was studied using a questionnaire about usual habits in the year. It listed 156 foods and drinks commonly had in Greece. Within ten years, nearly half of these fat participants developed high blood pressure and high blood sugar, though most of them preferred plant-based foods. The rest who ate quality plant- based foods, however , didn't have these health problems.
Regarding the quality of plant-based foods, healthier choices were linked with keeping normal blood pressure and blood sugar. On the contrary, eating unhealthy plant-based foods was connected with developing high blood pressure and high blood sugar. These relationships were stronger in women compared to men.

5 . Florence, a 17-year-old senior student in High School, was busy ,composing(编曲)a song. She plans to release an album(唱片)with three other music lovers whom she met at the 2016 Campus Singing Competition. Edward, 18, is another one of the four students to make their own album. Actually, he was the one who came up with this fun idea in the first place.
"Everyone loves music. Being a good way to express our feelings and emotions, music can tell something about who we are and our experience of the world. We hope we can use our music to touch our peers(同龄人)." Edward said.
The album includes 15 songs across three themes - love, campus life, and youth, with pop and electronic music styles. The inspiration for the songs came from the students' lives. Take the song Sea of Tranquility for example - it was written by Edward during a flight back to Chengdu after he took part in the China High School Biology Olympiad in summer. "The sky is clear and the ground looks small from the plane. This scene makes me feel calm and peaceful." Edward explained.
The songs were created one by one with the efforts of the four writers. But a challenge soon appeared. The students found that they didn't have enough money to produce the album. So to cut down their budget, they used an iPad and headphones to record the songs in an empty classroom on the weekend.
Apart from reducing their cost, they also tried to raise money through crowd funding on the internet. They raised more than 7,000 dollars before the album was released in October. "Thanks to all the supporters, we'll keep working on our own music." Edward said.

6 . 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.

7 . Looking back is a wonderful thing. It allows you to see what has led you here and, hopefully, how society has changed and improved.
Take, for instance, my career goal. First, I wanted, in 1999, to be a “farmer”, soon archaeologist, then driving instructor and somewhere along the way, footballer.
I had grown up in a football-loving family. I remember the exact moment when I said “I’m sad I can’t be a footballer” while watching the game with Dad as a pre-teen. He asked why not. “Because I’m not a boy.” He immediately responded, “You can, if you want to.” “Yeah, I suppose so,” I sighed, “but no one watches women’s football.”
Looking back, I can see exactly why I felt like that. At school, there was an unwritten rule that sports like hockey and netball were “girl” sports and rugby and football were for the boys. I’d never seen a women’s football match on TV. You see, you can’t be what you can’t see, and lack of representation leads, at best, to misunderstanding, and at worst, fear and negative opinions.
Today, the Lionesses will take on Scotland in the World Cup, and people across the world will tune in — over 950,000 tickets have been sold so far. But, although women’s football is one of FIFA’s best investments — with a pound for pound return, the majority of female players are earning under a fair wage. Some argue that’s because viewing statistics are lower than those of men’s, but the rise in support shows the demand is there. Hopefully, more investment will push female football forward.
Today, I’ll be cheering on the Lionesses, because it’ll mean talented, skillful female footballers being broadcast into millions of homes and maybe, just maybe, a little girl believing that she can also be a Lioness one day.

8 . It goes without saying that many Western wedding customs are completely different from those of Asian cultures. Some are so rooted in history that many Westerners have no idea whether they even exist.
Traditionally,June has been the most popular month for people to get married. One reason is that June 1 was the date of an ancient Roman festival celebrating the marriage of the god Jupiter and his wife Juno.Another reason will likely. astonish you. Centuries ago, taking a bath was not as common as it is today. Some people took a bath only once a year, typically in May. Since June was a time most wedding guests would not be too smelly, that month was preferred.
Another wedding custom is for the bride to "wear something old, something new,something borrowed,and something blue."Having something old is said to protect the newlyweds' future baby, while the new item shows optimism for the future. Meanwhile, something borrowed is meant to bring good luck, and something blue is a promise of being faithful. Lesser known is the fact that the bride is also supposed to have a sixpence in her shoe for prosperity(兴旺)。 Interestingly,in Sweden, brides are given two coins before getting married-one gold from her mother and the other silver from her father-also to put in her shoes. These fascinating customs show just how important certain wedding traditions are in Western cultures.
The concept of the “white wedding”， in which the bride wears a white wedding dress, is a familiar one. It is thought, mistakenly though, that this is a tradition that developed in ancient times and originates from the belief of white being a symbol of purity. Actually, the custom of brides wearing this color dates back less than 200 years and is attributed to the wedding of Queen Victoria. The queen's choice of white for her wedding was unusual for the time as other colors, especially red, were much more common.
After news of Victoria's highly publicized wedding to Prince Albert spread, not just around the United Kingdom,but to other nations including the United States,women began following in her footsteps and wearing white dresses at their wedding ceremonies. With white being the choice of a powerful royal figure like Queen Victoria, the color became associated with wealth. nobility. and the fashion-conscious.

9 . We have the most friends at the age of 26 after having spent the first quarter of our lives building up our friendship circle, a new research has claimed.
The research into friendship shows that our social circle peaks at 26 years and 7 months, at which we typically have five close friends. Women are the most popular at 25 years and 10 months, with men hitting the highest friendship point a little later at 27 years and 3 months.
The research, by Forever Friends, shows that about a third of adults meet their closest friends while at school, with about a fifth saying they meet them at work.
Social networks such as Facebook and Twitter now also play a major role in building new friendship. The research points out that 25 to 34-year-olds make 22 friends via Facebook, compared to 18 to 24-year-olds who make 12, and 35 to 44-year-olds who make just four.
Forever Friends’ relationship coach Sam Owen says, “It is no coincidence that over a third of us meet our best friends at school. It is a key time in our lives when friendship is growing through sharing notes, giving gifts, seeing each other regularly and laughing a lot. As adults we can often forget how powerful these small things are and how the little things can make a difference. ”
Later in life we find ourselves losing friends. Over half of us lose friendship through moving, while 36% say that over time they grow apart from close pals. Having children also causes 19% to drift away from childhood friends.
With growing pressures being put on friendship these days, it’s important to make time for our friendship.

10 . This is the SCIENCE IN THE NEWS; I’m Barbara Klein.
Animal experts say one of the world’s most beautiful and rarest kinds of big cats is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards still live free. The cats are also called Far Eastern Leopards.
Recently, their number has been reduced one by one. Some person shot a female Amur leopard, and then beat her to death. The animal’s body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia.
An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past five years. Mr. Collins said the death of even one adult female is a huge loss for the endangered cat. He noted that the killing reduced the possibility of cubs’ survival.
It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs. Four leopards were identified as females with cubs. In all, five or six cubs were recorded. Six to eight animals could not be identified.
Most of the land where the Amur leopard once lived was in China. New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts.
Mr. Pikuuov says adult Amur leopards need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard’s problem is for governments to provide protected space for wildlife.
