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 . There you are, looking through your WeChat moments or your Weibo feed, and you come across a post saying something like this: “I just got accepted to Harvard and 0xford! Are they sure they didn’t mix my applications up with somebody else’s?”
This person is clearly humblebragging. The term “humblebrag” was first coined back in 2010 by the late US comedian Harris Wittels, and it describes when someone makes a seemingly modest statement, but the actual purpose is to bring attention to something they are proud of.
The example above is a modesty-based humblebrag. The person wants to tell others: “I got accepted to Harvard and Oxford!” However, they don't want to seem too proud of their accomplishments. So, instead, they word it in a way to be more modest and bring down the importance of their achievements.
Although people who humblebrag think it will make them more likeable because they aren’t talking proudly about their victories, a study published in the Journal of Personality and Social Psychology showed that humblebragging actually has the opposite effect.
“Humblebragging doesn’t have the intended result because it seems insincere. That ‘poor me’ attitude combined with self-promotion does not lead to a favorable impression,” said Ovul Sezer, the lead author of the study and an assistant professor of organizational behavior at the University of North Carolina, US. “ Even simply bragging or complaining (抱怨) is better, because at least those messages are seen as more sincere.”
Sezer’s study also found that nearly 60% of humblebrags were complaint-based humblebragging, with most people humblebragging about their looks, followed by their money or wealth, and finally about their performance at work. “It’s such a common phenomenon. All of us know some people in our lives, whether in the social media or in the workplace, who do this annoying thing,” commented Sezer, adding that we all do it to some extent.
So, if you want to share your achievements with others, what’s the best way to do it then? Sezer suggests that people admit their self-promotion and harvest the rewards of being sincere. She also suggests finding a go-between, adding, “If someone brags for you, that’s the best thing that can happen to you, because then you don’t seem like you’re bragging.”

3 . Today we know Antarctica as an extreme environment containing ice and snow. But new research provides evidence that the area had a rainforest in the past.
The researchers collected a piece of Earth sediment (沉淀物) from under the seafloor off the coast of Antarctica. In the sediment they discovered forest material that was estimated to be about 90 million years old. This would have been in the Cretaceous Period, when dinosaurs were the main land animals. The sediment was removed by scientists on the research icebreaker RV Polarstern in the Amundsen Sea near Pine Island Glacier.
Johann Klages is a geologist with the Alfred Wegener Institute, Helmholtz Center for Polar and Marine Research in Germany. He was the lead writer of a study on the findings, published in the journal Nature. He said the sediment was collected from a depth of about 30 meters below the ocean floor. Klages said an examination showed that the material didn’t form in the ocean.
The researchers estimate that the area—about 900 kilometers from the South Pole—had average yearly temperatures of about 12 to 13 degrees Celsius. During the warmest summer months, average temperatures likely reached between 20 and 25 degrees Celsius. The soil included fine dirt particles (颗粒) and hard clay, as well as substances linked to at least 65 different kinds of plants, the study found. Klages added that the plants included trees, ferns and flowering plants. While no animal remains were found, Klages said there were likely dinosaurs, flying reptiles (爬行动物) and many insects in the environment.
The research represents new evidence of the major climate changes Earth has experienced in the past—and is currently undergoing today. The soil in the sediment dates back to the planet’s warmest period of the past 140 million years, with sea level about 170 meters higher than today. The researchers said that the rainforest environment in Antarctica was especially surprising because each year, the area experiences a four-month polar night when there is no sunlight to fuel plant life. Klages said no ice sheets were present during the time, but seasonal snowfall was likely.

4 . I was with my mom one day as we took a walk while window shopping. We both knew we wouldn't be buying much. I remember I was looking up at the people we passed as we walked. Ladies wore 5-inch heels and bright clothes. Men wore expensive perfumes and creams that wiped away the wrinkles on their faces. An uneasy feeling started to settle in my chest. I could deny it no longer and I was ashamed of my mom.
We were in a high-class neighborhood. We lived in a small, expensive apartment building at the edge of our county. Mom chose to move there because she knew the schools were good. I realized for the first time that we didn't belong there.
I could see the heavy lines around my mom's eyes and mouth. She wore cheap clothes and worm-out shoes. Her eyes were tired from working long hours to make ends meet, and her hair was too gray for her age. She was nothing extraordinary, yet at that moment, she stood out because she was just so plain. I didn't want to be seen with her although there was no one important around to see me anyway. I felt embarrassed about being at her side. We were standing in the middle of a high-end store, and she was holding a sweater.
Mom said, “Anna, this will look good on you. Do you want it?” It Was much too expensive, but I almost thoughtlessly answered “Yes”. Then I took a closer look at the small, tired woman with a big smile and a sweater in her hands, happy to be giving me something so nice. My words died in my throat. Her clothes were worn and old because she spent her money buying me new ones. She looked so tired because she was busy working to provide for me. She didn't wear jewelry or perfumes because she was content with spending what little money she had on me. Suddenly, my mom was beautiful and extraordinarily wonderful in my eyes. I was no longer ashamed of her, but of myself.
“Do you want it?” Mom repeated.
“No, thanks,” I replied.

5 . Laura Stone is the founder of Sydney by Kayak（皮划艇）, a company that offers guided kayak tours of Sydney Harbor in Australia. Not only did their business increase during the COVID-19, but one of their tours is actually more popular than ever.
A few years ago, Laura was paddling in the harbor when she noticed trash floating in the water. For reference, the United Nations Environment Program (UNEP) estimates that about 8 million tons of plastic end up in our oceans each year, causing big problems for wildlife and local plants. Laura was so shocked by the garbage in the water that she decided to dedicate a few paddles each week to trash cleanup. Incredibly, her clients were immediately on board with the idea, so Sydney by Kayak now leads four to five garbage-collecting tours every week!
At the start of the COVID-19, Laura thought her business would drop off as many others had. Instead, desperate for purpose and a way to get outdoors, people flocked to her “Clean Up Kayak” tours. They now routinely take about 441 pounds of garbage out of the harbor each week! “We've been quite surprised, even through the COVID-19, we've been very busy,” Laura said. “Because they can't travel, people are looking for something to do. That is not just good for them, but also good for the environment. ”
Each tour begins with participants preparing with some working tools. Some people come back many times for the satisfaction of collecting trash from the harbor. Julie Greening, for example, has done about 10 tours so far and says “every little bit is worth it”. “We're 7 billion people on this planet, so everyone does a little, but of course it's going to help, ” she said. “It's got to. ”

6 . High school freshmen always have a lot of questions on their minds. “What can I do when I grow up?” is one of them. It's definitely not too early to start thinking about this tough question. The following tips may help equip you for your future career.
Think beyond grades
Getting good grades in high school is important, but focusing only on straight A's could go wrong. Spending too much time on your schoolwork will leave you little time to explore opportunities outside of the classroom. Extracurricular (课外的) activities are necessary because they serve as form of career exploration. They can help you figure out your work preferences, like whether you are a “people person (擅长交际的人)”or prefer to work alone. Nowadays, most well-known colleges care about candidates' experiences as much as their grades.
Seek advice from grown-ups
Talk to your parents, teachers and school counselors (顾问) about how they started their careers. Even though you're not interested in the careers they are in, it would be useful to learn about the process which got them where they are now. If you find your friend's' mother doing worthwhile job by chance, ask her if job shadowing (体验工作) is possible in her company during vacation After all, seeing a typical day in the position you have an interest in can be an invaluable experience.
Start your search online
If you really have no idea what you can do when you grow up, take online career quizzes to get ideas about what professions naturally match your skills, interests and personality traits (特点). For the time being, you just need to focus on finding a field or two that interests you, rather than a specific career. Chances are you'll change your mind several times before finding a career that you want to stick to. Starting to explore career options now can at least help you decide what your potential major might be.

7 . If you have ever had a cat, or have watched one of the many funny cat videos online, you’ll know that cats have a mind of their own. A lot of the things they do are hard to understand—they like to climb up tall furniture, fit themselves in small spaces and attack small objects for no reason at all.
Now scientists have managed to figure out what exactly is going on in the brains of our little friends. According to Tony Buffington, a professor at Ohio State University in the US, cats’ strange behavior largely comes from their way of life back in the wild. “Cats today still have many of the same instincts that allowed them to live in the wild for millions of years.” he said in a TED Talk. “To them, our homes are their jungles.”
In the wild, cats are hunters. Their bodies and great balancing abilities allow them to climb to high spots to better look at the environment. Even though they don’t have to hunt any more in human houses, they still keep the old habit of viewing the living room from, for example, the top of the refrigerator.
Cats’ hunting instinct is also what makes them attack small things like keys and USB drives. In the wild, they hunt whatever they can get, and most of the animals they kill are small.
However, cats can also be prey. This explains why they like to stay in small spaces like drawers or washing machines— they are hiding, or they think they are hiding, from more dangerous animals. This is also why cats prefer a clean box: a smelly one could easily show enemies where they are.
Knowing how cats’ minds work is not only useful for better understanding them. It may also help cats’ owners to better meet cats’ needs. For example, owners could try to make climbing easier for cats by moving their furniture around. They could also use “food puzzles” to make eating feel more like hunting instead of just giving food to the cats.
1. According to Tony Buffington, ________.| A．cats’ strange behavior is difficult for humans to understand |

8 . British shoppers buy 2.15 million tons of clothing and shoes annually, yet UK citizens have an estimated €30 billion worth of unused clothing at the back of the wardrobe. But new technology could see the end of that, with the garments (衣服) themselves reminding the owners of their existence.
“Smart clothes” could help us clear out our wardrobes by sending messages or tweeting (发推文) us if they haven’t been worn for a good while. If these messages are ignored, the garments will get in touch with a clothing charity and ask to be reused, with an organization automatically sending out donation information. They could be programmed for a public sale where they are sold to whoever offers the highest price on eBay.
Academics at Birmingham City University are developing the connected “wardrobe” to encourage more suitable clothes consumption. The concept sees garments tagged (贴标签), using washable contactless technology.
Mark Brill, senior lecturer at the university, said, “Think of the surprise when an owner suddenly receives bids for items that they didn’t know were in their wardrobe.” “The connected wardrobe is a practical pleasant concept to encourage people to think about their clothing consumption. Finally, I hope it will encourage more appropriate fashion consumption,” he added. “Perhaps we can even move away from the idea of ‘ownership’ of clothing. When we’ve worn them enough, the items will pass themselves on to their next keeper. ”It follows in the footsteps of the “Internet of Things” —a concept that sees ordinary household items connecting to the Internet in order to share information. Now, the “Internet of Clothes” will see that neglected garments will tweet and text the owners, “asking” to be worn depending on the weather and frequency of wear. Clothes will keep track of other information, such as who owned them previously, as well as how much they originally cost, who made them and how much the worker was paid for them.

9 . Compassion is a desire within us to help others. With effort, we can translate compassion into actions. An experience last weekend showed me this is true. I work part-time in a supermarket across from a building for the elderly. These old people are our main customers, and it’s easy to lose patience over their slowness. But last Sunday, one aged gentleman appeared to teach me a valuable lesson. This untidy man walked up to my register with a box of biscuits. He said he was out of cash, had just moved into his room, and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day.
I couldn’t help staring at him. I wondered what kind of person he had been ten or twenty years before, and what he would be like if luck had gone his way. I had a hurt in my heart for this kind of human soul, all alone in the world. I told him that I was sorry, and the store rules didn’t allow me to do so. I felt stupid and unkind saying this, but I valued my job.
Just then, another man, standing behind the first, spoke up. “If anything,” he looked more pitiable, “Charge it to me,” was all he said.
What I had been feeling was pity. Pity is soft, safe and easy. Compassion, on the other hand, is caring in action. I thanked the second man but told him that was not allowed, either. Then I reached into my pocket and paid for the biscuits myself. I reached into my pocket because these two men had reached into my heart and taught me compassion.

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.
