1 . The use of AI (artificial intelligence) is becoming more common in many branches of industry and online shopping. Traditional lines of work, such as goods transport and driving, are developing in a similar direction although mainly out of public view. Scientists at the University of Göttingen have now investigated how efficient (高效的) the use of AI can be in the commercial management of trucks.
“Digital applications—as well as machine leaning, a kind of AI—are increasingly applied to operations and courses in the transport area,” explains Professor Matthias Klumpp from the Faculty of Economics. “The question in the commercial area, however, is whether or not this contributes to achieving goals.”
To answer this question, the researchers compared the work efficiency of truck drivers with their main use of AI applications. Looking at trade delivery by truck, they studied three groups: the first drove completely following human decision-making models; the second used a combination of human and machine; and the third depended completely on fully automated decisions.
The researchers found that an intelligent combination of human work and decision-making abilities with AI applications promises the highest transport and driving efficiency. “On average, the second group achieved the most efficient transport trips, with the fewest interventions (干预) and off-course from the best path.” one researcher said, “Clearly, neither a completely human decision-making structure nor a fully automated driving system can promise to meet current goods transport requirements.” The scientists therefore summarized that despite the progress of AI in the field of transportation by truck, human experience and decision-making abilities will still be necessary in the longer term. However, the challenge is that a wide range of training and qualification (资格) needs will come along by working with Al applications, especially for simple goods transport activities.

2 . Scientists have been trying to figure out how to alter the genes of humans for many years, and it looks like they’ve finally cracked (破解) the code. But while this may seem like a great step forward in science, some also believe that it’s one step back when it comes to ethics (道德准则). In August, a group of scientists from the USA and South Korea worked together to successfully edit a human embryo (胚胎) and remove a genetic mutation (突变) that would have led to heart disease, reported The Guardian. This was done with the help of CRISPR, a gene-editing tool that allows scientists to “cut and paste” human DNA.
Although this was the first example of an embryo’s genes being changed successfully, the advantages of gene editing have already been tested in living patients. In 2015, a five-month-old girl from the UK was saved after doctors used edited cells to fight off her cancer. As of today, she’s alive and well. And in the USA last year, scientists managed to remove HIV cells from several patients by editing the genes inside their bodies.
Some people hope that in the future, diseases or birth defects could simply be "edited out”. However, others believe this could lead to so-called designer babies, giving parents the option to choose everything from eye color to intelligence. “You could find wealthy parents buying the latest “upgrades” for their children, leading to even greater inequality than we already live with,” Marcy Camovsky, director of the San Francisco Center for Genetics, told BBC News.
In spite of these ethical concerns, experts say it’s not possible to create the “perfect” human being. Despite the progress scientists have made, we don’t understand human genes enough to give all unborn children great brainpower or amazing singing abilities. “Right now, we know nothing about genetic enhancement,” Hank Greely, a director at Stanford University, USA, told The New York Times. “We’re never going to be able to say, honestly, this embryo looks like it would score high on the two-part SAT.”
So it looks like if we want good exam results, or to impress people with our piano skills, we’ll have to stick with the old fashioned method of plain hard work---at least for now.

3 . “Don’t tell anyone”. We hear these words when someone tells a secret to us. But it can be hard to keep a secret. We often tend to “spill the beans”, even if we regret it later.
According to Asim Shah, professor in the Menninger Department of Psychiatry and Behavioral Sciences at Baylor College of Medicine, US, keeping a secret may well “become a burden”. This is because people often have an “obsessive and anxious urge to share it with someone”.
An earlier study, led by Anita E. Kelly, a scientist at the University of Notre Dame, US, suggested that keeping a secret could cause stress. People entrusted (受委托的) with secrets can suffer from depression, anxiety, and body aches, reported the Daily Mail.
But with secrets so often getting out, why do people share them at all?Shah explained that people often feel that it will help them keep a person as a friend. Another reason people share secrets is guilt over keeping it from someone close to them. A sense of distrust can develop when people who are close do not share it with each other. “Keeping or sharing secrets often puts people in a position of either gaining or losing the trust of someone,” according to Shah.
He added that talkative people could let secrets slip out (泄露). But this doesn’t mean that it is a good idea only to share secrets with quiet people. A quiet person may be someone who keeps everything inside. To tell such a person a secret may cause them stress, and make them talk about the secret.
Shah said that to judge whether to tell someone a secret, you’d better put yourself in their position. Think about how you would feel to be told that you mustn’t give the information away. Shah also recommended that if you accidentally give up someone’s secret you should come clean about it. Let the person know that their secret isn’t so secret anymore.

4 . Opera is an art form that celebrates the human voice. No other art form creates excitement and moves the heart in the way that opera does, especially when performed by a great singer. Opera is an important part of the Western classical music tradition. It uses music, words, and actions to bring a dramatic story to life. Opera started in Italy at the end of the 16th century and later became popular throughout Europe. Over the years, it has responded to various musicals. In recent decades, much wider audiences have been introduced to opera through modern recording technology. Some singers have become celebrities thanks to performing on radio, on TV, and in the cinema.
However, in recent years, opera has been facing serious challenges. One current challenge to opera is economic. The shortage of money raises the broader question of how much should be paid to support opera singers and other artists. Society seems to accept the large salaries paid to business managers and the multi-million-dollar contracts given to sports athletes. But what about opera singers? Somehow, people have the idea that artists can be creative only if they suffer in poverty, but this is unrealistic. If artists, including opera singers, lack the support they need, valuable talent is wasted.
Not only the shortage of money, but also the way money is managed in the opera world has led to hardships. Principal (主要的)singers are generally paid performance fees once they complete a show. They typically receive nothing during the many weeks of rehearsal (排练) before a show starts.
Another problem faced by opera is how to meet the demands of audiences who are influenced by popular entertainment. Pop singers are often judged as much on the basis of how they look as how they sound. These demands may be unrealistic and possibly harmful. Opera singers simply cannot make a sound big enough to fill a large theater or concert hall without a microphone if their body weight is too low. Emphasizing physical appearance over singing ability may cause audiences to miss out on the human voice at its best.
There are no easy solutions to opera's problems and there are many different opinions about the value of opera. However, every year many young people register for music courses with hopes and dreams of developing their talents in this special art form. The fact that opera has survived many obstacles and continues to attract the rising generation shows that it remains a respected art form full of value.

5 . When I arrived in London, I couldn't speak a word of English. Not even "hello". I was 18. I'd been working for my dad's restaurant in Milan and I wanted a new experience. My friend from home lived in London and he used to tell me how incredible it was. I was really bored, so I took my luggage and left.
I was so lost when I arrived at Stansted. To me, English sounded like Chinese. I only arrived with a few hundred pounds. I lived with my friend in East London for a while. I couldn't find a job for a month. Finally I found a waiter role in a restaurant. At the time, I had nothing else going on in my life. I used to get up, go to work, and sleep. It was no difference every day. Then one day on my lunch break, I saw a Gymbox. When I took a look in, there was an amazing Muay Thai (泰拳) class. I used to do boxing when I was 15 but I wasn't that serious about it. There and then I joined the gym and signed up for the Thai boxing team.
I fell in love with it. I never missed a session (一场) . I started training a lot and the head coach said to me one day, "Do you want to fight?" I knew that's what I wanted to do. He put me in competitions and I won my first nine amateur games. After watching me progress, he offered to help me fight professionally. However, at one point I had a motorcycle crash and was out for 18 months. This year I've fought in Milan and London. I'd say I'm about 12 fights away from becoming a winner
Sometimes I can't believe how far I've come from that day I arrived in England. I think everything that's happened has been because I'm committed. But anyone could do it. If you put in 100%, you'll get there. I'm just happy because I did a positive thing with my life. It feels good.

6 . 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?

7 . I have learned something about myself since I moved from Long Island to Florida three years ago. Even though I own a home in Port St. Lucie just minutes from the ocean, every winter an uncontrollable urge(冲动) wells up to fly back to Long Island even as others make their way south. I guess I am a snowbird stuck in reverse(反向).
Dulled by Florida's mild winters, I willingly suffer the cold weather on Long Island, the place I called home for 65 years. I'm like a bird that has lost its sense of timing and direction, my wings moving against routine.
So what makes me fly against the habits of snowbirds? The answer has a lot to do with my unwillingness to give up the things that define(给...下定义) who I am. Once I hear that the temperature on Long Island has fallen into the range of 40 to 50 degrees Fahrenheit, I begin to long for the sight and sound of a wood fire. I also long for the display of colours—first in the fall trees, and then in the lights around homes and at Rockefeller Center. Floridians decorate, too, but can't create the special feel of a New England winter. Moreover, when I return I can celebrate the holidays with people I haven't seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbours' children excitedly open gifts on Christmas? Even the first snowfall seems special.
While these simple pleasures are not unique to Long Island, they are some of the reasons I comeback. Who says you can't go home? I know I will be ordering a ticket this very night and cured of homesick(思乡病) tomorrow.

8 . At every turn in the Netherlands, the future of sustainable(可持续的) agriculture is taking shape—not in the meeting rooms of big companies but on thousands of modest family farms.
You can see it vividly on the farm run by Ted Duijvestijn and his brothers. At the Duijvestjns' 36-acre greenhouse near the old city of Delf, visitors wander among the deep green tomato plants, 20 feet tall. Rooted not in soil but in materials made from leaves and stalks, the plants are heavy with tomatoes—15 varieties in all—to suit the taste of the most demanding customers.
Since 2004, the Duijvestijns have declared resource independence on every front. The farm produces all of its own energy and fertilizer and even some of the packaging materials necessary for the crop's distribution and sale. The growing environment is kept at perfect temperatures year-round by geothermal heat(地热) that can be found under at least half of the Netherlands. Only rainwater is used for irrigation. Each kilogram of tomatoes from their plants requires less than 15 kilograms of water, compared with 61 kilograms for plants in open fields. Once each year the entire crop is regrown from seeds, and the old plants are processed to make packaging materials. The few pests that manage to enter the greenhouse are greeted by an army of fierce insects that shows no interest in tomatoes. The nutrition in the soil can be improved by growing plants that work with certain bacteria to produce their own fertilizer. In short. it's an entirely self-contained food system.
“Look at the island of Bali in Indonesia!” Ted explains. “For at least a thousand years, its farmers have raised ducks and fish within the same rice field. It's irrigated by the canal systems sculpted by human hands along mountains. They are our model.”

9 . If you're British or live in a Commonwealth nation, Christmas doesn't end on December 25.The day after Christmas is known as Boxing Day, and the relaxing holiday is a chance to allow the celebration for one more restful day.
But its name has nothing to do with the sport of boxing, and unlike the popular idea, did not appear from a need to return unwanted gifts or clean up trash produced by Christmas gifting.
There are several theories as to how that charitable tradition became known as "boxing".Some historians link the use of the term to boxes of donations that were laid in churches during the pre-Christmas season of Advent in the early days of Christianity during the second and third centuries A.D.The day after Christmas, the boxes were opened and the money was given away to the poor.
Another possible story for Boxing Day has to do with a tradition that formed in 19th century Victorian England, where servants sacrificed（牺牲）time with their own families to cater to their employers on Christmas.On the day after Christmas, employers would give the servants a rare day off and send them home with leftovers from the family's Christmas feast for their service.
Though the reasons are lost to history, Boxing Day charity eventually fell out of tradition---and was replaced with physical and material pleasures.Today, the holiday is linked with sports, with major football rugby, and cricket matches and horse races taking place on December 26.
December 26 is also a big shopping day throughout the UK and the Commonwealth.The holiday kicks off what is known as " Boxing Week" , during which retailers（零售商）try to move old stock and shoppers compete for one last bargain of the year.In recent years, though, the American tradition of Black Friday---massive sales that take place the day after Thanksgiving each November---has become popular in the United Kingdom and has largely overshadowed Boxing Week.
1. What kind of festival was Boxing Day probably in the beginning?| A．A charitable festival. | B．A religious festival. |
| C．A sports festival. | D．A business festival. |

10 . Two words can sum up the life of Dr. Catana Starks—determination and achievement. Now the story of one of her many accomplishments—she’s the first African-American woman in history to coach a male college sports team—is a movie!
The story is about Starks, who was the golf coach at her alma mater(母校) Tennessee State University, a traditionally Black College in Nashville. Starks’ distinctive coaching style and her achievements in the face of many challenges in her position and in life is what will leave audiences inspired. She had to drive the team bus, wash her players’ golf clothes, and had to constantly find places for her team to practice. Starks credits her strength to one woman in her life—her mother.
A native of Mobile, Alabama, Starks was diagnosed with severe asthma(哮喘). Doctors told her mother she could never participate in sports. “My mother, she had an almost mystical belief of not being limited by circumstances”, says Starks, “so I grew up with a basketball goal in the backyard.” Asthma wasn’t the only challenge; she grew up in the segregated(被隔离的) South of the 1940s, “I learned to swim. I had to walk four miles in Mobile to get to a Black pool”.
After getting the men’s golf coach job, Starks couldn’t find golfers. None of the males on campus would play. “Initially that didn’t work out because I was female,” said Starks. She had to innovate by recruiting internationally, via telephone. The calls attracted players from Sweden to South Africa. During nearly twenty years in her charge her former players have distinguished themselves throughout the world including: Sam Puryear, the former Michigan State University golf coach-the first African American in its history, and Robert Dinwiddie, an All-American golfer at TSU and a current member of the European Tour having achieved three consecutive Top-10 finishes in South Africa. Starks’ determination really paid off when the T-State Tigers won the National Minority Golf Championship in 2005. And another distinction for her career, ninety percent of the players graduated!
