While improvements in education are forecast to reduce dementia cases by 6.2 million in2050, researchers said this would be canceled out by trends in obesity. high blood sugar and smoking, which are estimated to cause an additional 6.8 million cases, the Guardian reported.

Risk factors for dementia also include stress, depression, physical inactivity, diabetes, heavy alcohol consumption, head injury, exposure to air pollution and low education, researchers said.

The rate of dementia is estimated to rise in every country, ranging from a 1,926% increase in Qatar to a 27% increase in Japan, while dementia cases in the U.S. are expected to increase by about 99.67%.

Researchers estimated that dementia cases would increase by roughly 117% by 2050 due to growth of the elderly population alone, a factor forecast to have the severest impact in East Asia. To reduce the risk of dementia, policymakers must support low-cost programs promoting exercise, a healthy diet and quitting smoking, lead author Emma Nichols，a researcher at the University of Washington's Institute for Health Metrics and Evaluation, told the Guardian.

Dementia is a syndrome(综合症),usually progressive, which harms memory and other functions of thought beyond what would usually be expected from aging. Though dementia can result from Alzheimer's disease or a stroke, it is not an unavoidable consequence of aging, the World Health Organization said. A 2020 study published by the Lancet suggested that low education might be a risk factor for dementia, because improved health education helps decrease the risk of head injury or of too much alcohol drinking. $818 billion is the annual global cost of treating dementia，the WHO estimated in 2017.Famous figures who were diagnosed with dementia include actress Rita Hayworth, actor James Stewart, former President Ronald Reagan and former UK Prime Minister Margaret Thatcher.

It raises a troubling question for all of us—when will a machine be able to do my job? Katja Grace, a research associate at the University of Oxford's Future of Humanity Institute, and her colleagues from the AI Impacts project and the Machine Intelligence Research Institute, have surveyed 352 scientists and compiled (汇集) their answers into predictions about how long it may take for machines to outperform humans on various tasks.

The good news is that many of us will probably be safe in our jobs for some time to come. The researchers predict there is a 50% chance that machines will be capable of taking over all human jobs in 120 years.

"One of the biggest surprises was the overall lateness of the predictions," says Grace. "I expected the amazing progress in machine learning in recent years, plus the fact that we were only talking to machine learning researchers, to make the estimates earlier."

"I am a bit sceptical of some of the timelines given for tasks that involve physical manipulation (操纵)," says Jeremy Wyatt, professor of robotics and artificial intelligence at the University of Birmingham. "It is one thing doing it in the lab, and quite another having a robot that can do a job reliably in the real world better than a human."

Manipulating physical objects in the real world—figuring out what to manipulate, and how, in a random, changing environment—is an incredibly complex job for a machine. Tasks that don't involve physical manipulation are easier to teach.

Perhaps the hardest jobs for machines to perform are those that take years of training for humans to excel at. These often involve intuitive (直觉的) decision making, complex physical environments or abstract thinking—all things computers struggle with.

[1] Inakadate is considered the home of Tanbo art, a rice field art form. Its story as a world-renowned tourist destination began in the early 1990s, when local authorities realized that youths were moving to large urban centers continuously, and started brainstorming for ways of reviving (焕发生机) the village. One of the proposed ideas was an art form inspired by the local's traditional rice farming, done by hand for hundreds of years. Tanbo art involved the use of different-color rice varieties to turn local rice fields into giant canvases (画布) for complicated designs that revealed their beauty when viewed from above.

[2] The first rice field artwork was unveiled in 1993, when purple and yellow rice plants were used to create a detailed picture of Mt. Iwaki — the highest mountain in Aomori — along with easily recognized characters. A viewing platform was set up somewhere above the rice field, from which people could admire the unique artwork in all its glory. The project was so successful that Inakadate authorities decided to turn it into a yearly event.

[3] To create the impressively massive rice field artworks, locals use a technique which involves surveying the rice fields, perspective drawing (透视绘图), and the handmade plantation of various types of rice plants to create the desired visual effect. Tanbo art has come a long way in the last three decades, with designs gradually becoming larger and more complicated.

[4] Many locals say that Tanbo art has saved Inakadate, bringing in impressive numbers of people from all over the world and boosting the local economy. According to CoolJP, around 200,000 people flocked to Inakadate to see its unique artworks in 2006, and by 2016 that number had ballooned to around 340,000.

When was the last time you went to an interview? How did it go? There are lots of things to remember and prepare. However, one important thing to think about is your body language as it can really help you get the job. With a good understanding of body language in interviews, you can communicate the right messages, and even understand what the interviewer is saying or thinking. Here are some really useful things you need to know about body language in interviews.

Greetings

When greeting the interviewer, smile, look him in the eye and introduce yourself in a strong and confident voice. Also, remember that in most English-speaking countries (the UK, the USA, Australia, Canada, etc.), a firm handshake is seen as a sign of trust; and a limp handshake could make you appear weak or disinterested. Experts recommend waiting for the interviewer to extend his hand first.

Palms (手掌)

When possible, keep your palms facing up to show that you're open, trustworthy and interested. Research has shown that if we can't see the other person's open palms, we subconsciously become suspicious of them.

Mirroring

Mirroring involves copying what someone does with their body. For example, if the interviewer places a hand on their leg, you should do the same, but not too obviously. Experts have shown that mirroring someone can make him like you, or even think that you're more honest and trustworthy. However, be careful—if the other person knows about this technique, he might notice you doing it.

Sitting position

When sitting, if you lean back, you could appear lazy or arrogant; and if you lean forward too much, you might appear aggressive. The ideal posture is to sit with your back straight and your shoulders back a bit, leaning in very slightly. Sit with your legs slightly apart to give the impression of self-confidence and try to angle your knees and feet so they're pointing towards the interviewer.

My great-grandmother, my grandmother, and my mother are teachers, and so are all my family. My mother had a fixed idea that I would become a teacher, too. Although I respected her and was indeed skilled at teaching something to my little cousins, I didn't agree that I should naturally follow in my mother's footsteps.

When I was a teenager, my mother happened to take me to a hospital which was run by one of her friends. It was the first time I had seen a busy medical environment in real life in person. Finding that I was curious about treating patients, my mother's friend Dr. Lee offered me an opportunity to shadow him (跟他实地参观) for a day. I eagerly accepted his offer! Observing the doctors and nurses in action, I felt a mix of anxiety and excitement. Seeing the healing (治愈) process and the impact of medical care on patients was a profoundly moving experience. I figured being a doctor would be the most rewarding career in the world. From that day, a thought formed in my mind that I wanted to become a doctor, but I doubted whether my mother would support me. After all, it was a completely different path from what she had planned for me. Therefore, I kept the thought to myself, because I knew she would still insist on holding onto her previous idea.

Anyway, besides discussing with my mother about teaching, I would often visit Dr. Lee's hospital. Gradually, I got familiar with the medical equipment and procedures, and I learned a lot about healthcare, such as how to take vital signs (测生命体征), how to assist in minor surgeries, and so on. But what I had learned in the hospital just left me wanting more, so I decided to go to college to become a professional doctor.

Seven years later, Dunlop published her first book, Sichuan Cookery,(praise) as "one of the top 10 cookbooks of all time". So far, she has published five books about Chinese cuisines, showing her deep understanding of the food culture that(run) in the blood of Chinese people.

Having studied Chinese food culture for nearly 20 years, she regards Jiangnan the center of the nation's gastronomy (美食学).

Know your own culture

One of the best ways to understand other people's cultures is to first consider your own. Most of us don't realize that our customs and beliefs might seem strange to someone else. Don't think of your own way of life as the only normal one and everyone else's to be strange.

Learn about a different culture

Maybe you've recently met someone from a different culture, or you're curious about how different people live. When you meet people from a different culture, ask them about their lives. Also, you can read books, watch movies or listen to radio shows. The more you learn, the more likely you will get used to greeting cultural differences with curiosity rather than doubt.

Differences between us are what make life so interesting, so just accept the differences between yourself and your friends from different cultures. The best way to respect people from other cultures is to strike a balance between curiosity and appreciation:. Also, learn how to just silently observe and appreciate the differences that make us unique.

A. Respect other cultures.

B. Appreciate the differences.

C. Ask questions if your friends are open to it.

D. In this way, you may find it hard to know your own culture.

E. Otherwise, it's hard to approach those differences with respect.

F. Here are some tips for learning more about them and about yourself.

G. These will help you get an insider's view on a different culture.

As children's free time and imaginations become more and more tightly joined to the social media, we need to understand that uncontrolled access to the Internet comes at a cost. This spring, I visited with a group of high school students in Connecticut to have a conversation about the role that social media plays in their daily lives and in their mental health. More children today report feeling depressed, lonely, and disconnected than ever before.

There are countless problems with children and teenagers using social media. But the high schoolers with whom I met alerted me to a hidden result of teenagers' growing addiction to social media: the death of exploration and discovery. Algorithmic recommendations now do the work of discovering and pursuing interests, finding community, and learning about the world. Kids today are, simply put, not learning how to be curious, critical adults—and they don't seem to know what they've lost.

We all know the journeys in life matter just as much as the destinations. It is the sweat to get the outcome that makes the outcome more fulfilling and satisfying.

What the kids I spoke to did not know is that these algorithms have been designed in a way that unavoidably makes and keeps users unhappy. Social media companies know that content that generates negative feelings holds our attention longer than that which makes us feel good. If you are a teenager feeling bad about yourself, your social media feed will keep delivering you videos and pictures that are likely to produce negative feelings.

We should take some measures. Teenagers and kids are to be inspired to determine if we will really be happier as a species when machines and algorithms do all the work for us, or if fulfillment only comes when humans actually do the work, searching and discovering, of being human.

To share the joy of its success at the chicken farm in Chishui, Guizhou province, the Tencent Cloud Artificial Intelligence Class(TCAIC) — a program set up by the university and tech giant Tencent — offered the free soup to all teachers and students at the university's cafeteria. As Spring Festival is on the way, the students in class said they decided to have the cafeteria turn these black-boned birds into "AI chicken soup" before the holiday to give teachers and students a taste of technology.

In the last eight months, about a dozen students from the class have devoted themselves to developing an intelligent farming system for the Silkie chickens in Chishui. Students learned from their previous experience in developing an AI goose type in Shantou, Guangdong, in 2022. Previously, they successfully improved the overall survival rate of the Lion-Head goose (African goose) by 30 percent because they made use of technologies such as "goose body recognition". Based on this success, the students risked the Silkie chicken farm in Chishui.

Using deep learning and computer vision technologies, they successfully identified 250,000 Silkie chickens to create a completed database. The result was the world's first intelligent Silkie chicken farming system, which increased the farm's output by 30 percent.

"This farming system combines the old tradition of free-range (自由放养的) farming and modern technology. It contributed to the production of high-quality Silkie chickens through the use of cloud technology," said Feng Yuhong, the Tencent class adviser. Zhang Xiaohong, the university's vice-president, also announced that the project not only marks a significant advancement in the application of AI in agriculture, but also enables students to deepen their understanding of technology and develop their practical skills.

From farming stock, Mary first went to work with her father at the age of 10. Profits from his coffee crop covered her school fees. She married into coffee too, with her husband giving her 100 trees as a wedding present. But Mary's since planted more than 300 herself and joined a women's cooperative. "The aim was to reduce the dependence of women on men in coffee." Mary says, though husbands are allowed to join too—as they tend to own the coffee plantations and support their wives. "More women have started to plant their own coffee." she says.

Mary rises early every day to pick the coffee cherries. "It's hard work but when you concentrate it can become easy." says Mary. After gathering the ripe fruit, she puts it in a bucket of water to weed out the unhealthy cherries. The beans are then fermented (发酵) in water for at least two days before being laid out to dry in direct sunlight. Once dried, the beans are gathered up and later collected by Endiro Coffee, a social enterprise working with women-led, organic farms. The coffee is later milled, roasted and ground, ready for use.

It hasn't been an easy journey for the Bududa farmers, who've faced annual landslides for the past 15 years. In 2018, Mary's mother's house was destroyed and she lost some of her coffee plantations. She dreams of living in a solidly built house with water nearby, so she doesn't have to trek (跋涉) a long way to fetch it－but these will take time to save for. "I've worked a lot and I don't want to stop, but I want my money to work for me." she says.

These hikes on some of Europe's best long distance trails (路线) offer a chance to reconnect with the world, get some energetic exercise and enjoy peaceful moments in some of the Europe's most beautiful scenery.

Hyssna Trail, Sweden

West Sweden's quiet beauty is the star of the show on this 40-kilometer, two-day hike. The round trail starts at Hyssna's12th century church, which can be accessed by bus from Gothenburg in just 40 minutes. The route is well guided, with plenty of picnic spots and a well appointed camp site.

Karhunkierros Trall, Finland

Finnish Lapland is well-known as a winter destination, with magical aurora borealis (极光) and an amazing ancient Sami culture. It's also home to the 82-kilometer Karhunkierros Trail, the most well-known long-distance walk in Finland. The path begins in Hautajarvi village in Lapland's Salla and ends at the Rukatunturi Fell in Kuusamo, taking four days.

King Charles III England Coastal Path, England

Covering an area of 4, 300 kilometers, the England Coastal Path is a lifetime's attempt for those who wish to cover every step. And it can be easily broken down into areas, with northwest, northeast, east, southeast and southwest regions to explore. Walking around the coast of Cornwall will leave anyone energetic.

Slovenian Mountain Trail, Slovenia

It's no surprise that the Slovenia Mountain Trail has become so popular. This attractive trail covering some 616 kilometers runs from Maribor in the country's northeast, all the way to Ankaran. And while doing it all together over 28 days might seem extreme, it can be broken into smaller regions. There are paths through the ancient forests and wetlands of the Pohorje Hills or across the Julian Alos.

When I was in seventh grade, my parents paid a tutor(家庭教师) forty dollars a week for her coming to my house and helping me with math. It ended up raising my marks from fifty to fifty-five.

I had to admit it was mainly my fault. Maybe I should have concentrated my math from the beginning. But studying math was a tough thing. Sitting on a chair to work on confusing math problems for two hours was a slow and painful process. During the process, I would fidget(坐立不安) and have many trips to the refrigerator in an attempt to get off that chair for at least five minutes.

During math tests, my teachers would always stay by my desk. My teachers and friends would frequently ask the question after tests," How's your math this time?" So I became extremely afraid of math. While normal people of my age were scared of some insects and adventurous travels, I feared anything to do with numbers. The thought of a teacher picking on me in class made me feel scared. The red marks on the test paper were also terrifying.

My fear of math got worse in ninth grade. Every report card I received from my new math teacher Ms Robbins had the comment to encourage me, "I'm glad to do what I can to help you." But I couldn't tell her the real reason why I didn't ask for help-I didn't want to be considered stupid. Every question I had was, in my opinion at the time, something that the whole class had understood but I. So instead, I ended up not caring about anything related to math, without working hard on math at all. And I concluded everything would work out in the end

Eventually, my classmates and I took the final test that would lead to our graduation from middle school and stepping into high school. Days after the exam-- on a rainy summer morning, Ms. Robbins called me.

With worry and uncertainty, I entered her office.

I am a specially (train) clown doctor whose job is to cheer up patients, their families and the hospital staff doing magic tricks, singing songs and telling stories and silly jokes.

I (choose) this career because of the experience of going to hospital when was a kid , and I spent much of my time there feeling (fright) and more than a little bored, so I think being a clown doctor can help people by entertaining them.

Wearing my curly rainbow wig and a big red nose, I walk into the waiting room, there is a familiar atmosphere of boredom and tension. There, I spot a little girl called Lara, ankle has got injured and is twice its normal size. The doctors and nurses are treating her injury. (get) her attention, I begin to do a magic trick, which has made her scared and anxious look replaced with loud laughter. (see) their daughter so much happier has in turn made Lara's parents more relaxed.

I hope clown doctors can help make the hospital friendlier place to visit. After all, is really true that laughter is the best medicine.

Have you ever embarrassed yourself in public and were laughed at for it? And it's okay — we should even have a laugh about them.

Laughing at yourself means accepting who you really are. You may feel bad about yourself because of past misfortune. However, it's normal to be imperfect. What's important is that you should be honest with yourself about who you are. You won't be able to laugh at yourself without self-acceptance.

Laughing at yourself helps increase your confidence. When you're able to stay optimistic and laugh at yourself, you are likely to be more successful in life. More importantly, it helps you realize your own weaknesses, so you know which areas to do better in.

Laughing at someone else may hurt their feelings even if you didn't intend to, while laughing at yourself does not. You might even bring a smile to their faces. Don't worry about losing respect from others, because people actually appreciate it when you laugh at yourself. Laughing at yourself shows that you have the courage to do so and you're being real about your imperfections, making people think you are likable.

As we all know, humans all make mistakes. So instead of blaming yourself, try to think of your mistakes in a positive way and accept yourself as you are. So please remember the above words.

A. Laughing at yourself makes you popular.

B. Accept yourself despite your imperfections.

C. You should try to understand yourself better.

D. Chances are that we all have these kinds of experiences.

E. Laughing at yourself changes an ideal image of yourself.

F. Learn to laugh at yourself and you will be more attractive.

G. This is because laughing at yourself helps lift your mood in face of difficulties.

White noise refers to a noise that has a mixture of all the audible (听得见的) frequencies that the human ear can detect. It is a combination of all the frequencies of sound played at once. It can cover the sounds of other noises because of its various frequencies, leading many people to experience its calming effects.

Studies have that listening to white noise positively found affects sleep. For example, people living in a high-noise area of New York City fell asleep faster and spent more of their time in bed asleep while listening to white noise. In another study, listening to white noise through headphones improved sleep quality for seriously ill patients in a loud hospital room. However, more research is needed to confirm whether the characteristics of white noise itself improve sleep or whether the sound primarily helps by covering background noise.

However, a recent analysis of multiple studies looking at white noise's effect on sleep has produced mixed results. The researchers are doubtful about the quality of existing evidence and conclude that further research is necessary in order to widely recommend white noise as a sleep aid. They also note that in some instances, white noise can disturb a person's sleep and may affect their hearing.

Despite that, researchers are still optimistic that the steady hum of white noise might reduce a sleeper's sensitivity to unpredictable noises from the environment, such as transportation sounds like cars and planes, which are considered a major contributor to poor sleep.

Here is the joke which the experts decided was the funniest joke in the world:

Two hunters were out in the woods. One of them fell to the ground. He didn't seem to be breathing; his eyes were closed. The other hunter took out his mobile phone and called the emergency services. "My friend is dead!" he cried to the operator. "What can I do?" The operator said, "Don't worry. First, make sure he's dead." There was a silence, and then a shot was heard. Bang! The hunter's voice came back on the line. He said, "OK, now what?"

This is perhaps amusing. Culturally, it depends on us knowing that often hunters are not considered to be very intelligent people, and that often they are quite violent. But perhaps this is not so all over the world. It's also quite a black joke — a joke about something that isn't really a funny subject.

The experts also found the second funniest joke in the world. Here it is:

Sherlock Holmes and Dr Watson went on a camping trip. After dinner, they went to sleep. Some hours later, Holmes woke up. "Watson, look up at the sky and tell me what you see." "I see millions of stars, Holmes" replied Watson. "And what do you infer from that?" "Well, there are billions of stars...we are a small part of the universe." "Watson, you idiot!" he said. "Someone has stolen our tent!"

I personally think this is better. Can scientists in the end decide what is funny? Some things are much too complicated, even for scientists.

Other Chinese courses opening across world show the increasing demand for Chinese-speaking talent. Russia included Mandarin (普通话) as an elective foreign language in the country's college entrance exam. Following English, German, French, and Spanish, Mandarin has become the fifth elective test item for the exam, according to Sergey Kravtsov, Deputy Minister of Russia's Ministry of Education and Science.

Spain, for example, has more than 40,000 people learning Chinese; last year some 8,000 took the Chinese Proficiency Test (HSK) exam, ranking first among the member states of the European Union, according to Xinhua News Agency.

In the US, learning Chinese has been thriving for a number of years and is now a popular choice for American children, especially those who born in elite (精英) families. The children are exposed to the language at an early age as their parents believe mastering Chinese will help them build successful international careers.

Ten miles away stood a house with shiny red walls, a green garden and an apple tree. A young girl's face would be seen reflecting from one of the large glassy windows. Her name is Maggie. Her eyes were sparkling and on her face there was a smile which could light a million candles. She seemed to be longing for a chance to play like a young child, but she had no strength in her legs because she and her family met with an accident, in which she lost both her legs.

But her spirit was strong. She would be inspired by seeing birds fly. The flying eagle would make her want to fly. She was lonely. She longed for a true friend who would talk to her and teach her to fly or at least tell her stories about soaring into the blue sky.

One evening, Maggie slowly rolled her wheelchair to the giant window and looked out to the many houses that lay across the road. Suddenly she heard someone singing and then could see an old man in a pilot suit singing in glory. The beautiful sound and the melody made the little girl happy. Suddenly he stopped and gazed up toward her. "What are you staring at?" he said angrily. "You think I'm a circus clown? (马戏团小丑)" "No, Sir. I was just listening to you. You sing very well," she said. "I don't need your praises. I don't need anyone!" he shouted. He started to walk to his house and shut the door. Tears rolled down from her apple-red cheeks as the man shouted at her. She was lonely.

Next morning, Maggie pushed her wheelchair across the garden to the stone road as little children played hide-and-seek around her. Suddenly out of nowhere a loading truck came rumbling across toward her. Terrified, she tried to move away from its path but the wheels of her chair were stuck. "Oh my," she thought as the truck came in her direction fast, with the driver unaware of the obstruction in front of him. She screamed loudly but in a split second she was pulled out of her wheelchair by someone and fell on the ground. She closed her eyes and shivered as the truck passed her whistling. As she opened her eyes, she could see a man standing beside her.
