The story of Ni Xialian, the 59-year-old member of Luxembourg's national sports team and the (old) Olympic table tennis player in the Chengdu World Table Tennis Championships competition, has gone viral on Chinese social media.

Born in Shanghai in 1963, Ni Xialian (successful) won several championships as part of China's national table tennis team. She later moved to Germany and then (settle) down in Luxembourg in 1991.

"I retired from China's national team in 1986. Since table tennis was not listed as an event at the Olympic Games 1988, I missed the chance (fight) for our country," Ni said in an interview with Xinmin Evening.

Ni attended the Summer Olympics in Sydney  a representative of Luxembourg in 2000,  (kick) off her career as an Olympian at the age of 37. She then joined four more Olympic Games, including those in Beijing and London.

Ni said she believes she stands as a symbol on the field for Chinese everywhere. "I was born in China and received systematic training in Shanghai, developed my solid skills and capability of reading games. It's very important." Ni told The Migu Sports News in the Shanghai dialect. "I just feel (honor) to compete in the Olympics. Even though I don't represent Team China anymore, I think that may be more meaningful because we need the (communicate) between East and West."

Winnie the Pooh was a source of comfort for me while I was growing up. Not only did he help me get to sleep, he also helped me understand the importance of 1 . Little did I then 2  that his words would provide more 3  than I could ever imagine.

I have spent the past five months in isolation (隔离). In that time, I have 4 loss and grief. One of the biggest 5 has been not being able to see those closest to me. This 6 me of the stories that I have read in Winnie the Pooh. He tells me that despite 7 we are stronger and braver than we think. Isolation has taught me how to 8 in the face of adversity (逆境). Time spent with friends has 9 . I find that I am spending much more time on phone calls and 10 . My friendships have become much more 11 , returning to play. Through the children's stories that I have heard, and my time in isolation, I have learnt the importance of 12 . Homeless children often talk about their friends and their need to play to make light of a bad 13 . This proves Pooh's second point: we are 14 than we think.

Winnie the Pooh's words have taught me a lot of things. Most 15 , despite distance, friendship makes us stronger, braver, and smarter. If it weren't for the 16 that I have had during isolation I wouldn't have 17 any of these things. I have 18 the words of Winnie the Pooh to remind me that despite the distance 19 between me and those that I love, I can still carry my friendships 20 .

How to Organize a Garage Sale

Have you been considering the idea of having a garage sale, but aren't sure if it will be a success? Stay tuned to learn more about the tips!

Online Advertising is Key

About two weeks before your garage sale, you'll want to advertise as much as possible. . Advertise your sale so you can reach people who live in your neighborhood and beyond.

Create Lots of Signage

! Be sure to create plenty of large and colorful signs to direct people to your garage sale. Purchase a few poster boards, markers, glitter, stencils, and get decorating! Once you're done, hang the signs on select trees and poles in your neighborhood. It's critical that you clearly mark the date of your garage sale on every sign.

Create a Fun and Welcoming Atmosphere

Music, food, drinks, games, and more are fun for any occasion. . When you create a fun and welcoming atmosphere, you'll attract more visitors. You don't host a garage sale every day, so why not live a little?

Remember that not all prices are set in stone. While you are free to charge whatever you'd like, keep in mind that people may try to bargain, and that's a good thing. The goal is to sell as much as possible. When a customer drives a good bargain, they put money in your pocket and take those unwanted items off your hands!

Team Up With Another Garage Sale

Community garage sales are a great way to meet new people and get rid of unwanted items in your home. According to The Spruce, "garage sales advertised as neighborhood or community yard sale tend to attract more customers." . Community garage sales are great in terms of organization, so you can delegate（授权）certain roles and responsibilities to those involved.

A. Be Willing to Negotiate

B. Make a Fixed Charge

C. Paper advertisement isn't dead

D. The same goes for garage sales

E. They choose garage sales when they're financially difficult

F. The Internet is full of valuable information and opportunities

G. That's because people know there will be more variety at the sale

A new study shows that when heavy cognitive (认知的) work is lasted for several hours, it causes potentially poisonous materials to build up in the part of the brain known as the prefrontal cortex (前额叶). This in turn changes your control over decisions, so you shift toward low-cost actions requiring no effort or waiting as cognitive tiredness sets in.

Influential theories suggested that tiredness is a sort of illusion (错觉) cooked up by the brain to make us stop whatever we are doing and turn to a more pleasing activity but new findings show that cognitive work results in a true functional change — accumulation of poisonous materials — so tiredness would indeed be a signal that makes us stop working but for a different aim: to preserve the perfection of brain functioning.

To look for evidence of this, researchers monitored brain chemistry over the course of a workday. They looked at two groups of people: those who needed to think hard and those who had relatively easier cognitive tasks.

They saw signs of tiredness only in the group doing hard work. Those in that group also showed in their choices a shift toward options with rewards at short delay with little effort. Critically, they also had higher levels of poisonous materials in the brain. Together with earlier evidence, the researchers say it supports the concept that poisonous materials accumulation makes further activation of the prefrontal cortex more costly, such that cognitive control is more difficult after a mentally tough workday.

So, is there some way around this limitation of our brain's ability to think hard? The answer is negative. But there is good evidence that poisonous materials disappear in the brain during rest and sleep. The study result may have other practical uses. For example, the researchers say, monitoring of prefrontal metabolites (前额代谢物) could help to detect severe mental tiredness. Such an ability may help adjust work plans to avoid burnout. They also advise people to avoid making important decisions when they're tired.

The idea that the standard human body temperature is about 98.6℉ (37℃) was first presented by the German physician Carl Reinhold August Wunderlich in 1851. Since then, it's become so widely accepted that it serves as a touchstone for health—a diagnostic tool used by physicians and parents as a basic indicator if someone is sick or well.

However, it turns out that this well-established fact isn't, in fact, correct—or, to put it more accurately, human beings have been getting cooler over the years.

Recent studies have shown that temperature records of groups of people have tended to run low compared to the accepted norm (标准), so the Stanford team, led by Julie Parsonnet, MD, professor of medicine and of health research and policy, decided to do a more in-depth study to compare modern measurements with historical records to try to identify body temperature trends and, perhaps, uncover the reason why this cooling is happening.

For their research, the Stanford team looked at three distinct datasets (数据集) from three historical periods. One was military service records, medical records, and pension records from Union Army veterans of the American Civil War that were compiled from 1862 to 1930. The second was from the US National Health and Nutrition Examination Survey Ⅰ collected between 1971 and 1975, and the third from adult patients visiting Stanford Health Care from 2007 to 2017.

In all, the team went through 677,423 temperature measurements, making sure that temperatures recorded were accurate rather than the result of poorly designed thermometers (温度计). They did this by looking at the change in temperature inside each group over time to ensure that the curves (曲线) showing a decrease were consistent between the datasets.

At the end of the day, the team found that men born in the 21st century had an average body temperature of 0.59℃ lower than those born in the early 19th century, while modern women showed an average decrease of 0.32℃ compared to those born in the 1890s. Together, this means that human body temperatures have fallen by 0.03℃ per decade.

When hurricanes left a path of destruction in Puerto Rico, Pennsylvania College of Technology student Natascha G. Santaella felt a variety of painful emotions.

"I spent around six days stressing and having a very hard time with me having all the luxuries I currently do and my family not having any," the Guaynabo, Puerto Rico, resident said. Santaella said that her hometown is without power and water, and people there are scared of what is to come.

To reduce her stress, Santaella, who is studying for an associate degree in baking and pastry arts, immersed(沉浸) herself in what she knows best: baking. "It started out as just baking bread and shipping it to the island to then be dispersed to the people, but I found that was very expensive for me to do alone, so I spoke with Chef Charles Niedermyer, our instructor of baking and pastry arts about a sale of baked goods in the college's Bush Campus Center."

"Natascha is a bright energetic young lady with a big heart,"Niedermyer said. "I was not surprised to find her in my office, looking for ways to help the people of Puerto Rico."

To prepare, Santaella had multiple meetings with Niedermyer, spent hours finalizing recipes, designed signage(标志) and decorations, and got friends to staff the sale table with her. And then there was the baking: Santaella and two friends in the baking and pastry arts major spent six hours baking 90loaves of bread,24 dozen dinner rolls and 30 cheesecakes in a variety of flavors.

During the six-hour sale, Santaella and her friends raised more than $1,000 for United for PuertoRico, an initiative designed to provide aid and support to those affected in Puerto Rico by the passage of Hurricane Irma and Hurricane Maria.

"I hope to mainly increase awareness of what has happened, and to show people that there are Puerto Rican students at this school," Santaella said. "I hope that others had the great experience I had with all my teachers and how understanding they were with me."

When it come to the ocean, its pollution is becoming more and more serious. World Ocean Day, fall on June 8th, is aimed at raising aware of preserving the ocean.

The ocean plays a key role in our world. Not only does ocean offered us sufficient food, and it maintains the balance of nature. Thus, it is crucial for us preserve the ocean. First of all, place importance in our daily actions. For example, garbage can't be thrown into the ocean.

What's the more, we can also hand out booklets to call on more people to preserve the ocean. The more people are involved, the good the ocean environment is.

All in all, it is high time that we devoted ourselves to preserving the ocean. To preserve the ocean is to protect ourself.

Bilibili, a (lead) video platform popular among China's younger generation, (announce) on Thursday the phrase of the year on its site to be "You Ya", or "elegant/elegance" when (translate) literally.

Elegant/elegance is often used to praise someone who is stronghearted or resilient, or good at (stay) calm. No matter what the situation is, he or she can maintain a calm and steady mentality.

 (traditional), elegance is often associated with middle — and high-class groups or those with high academic backgrounds. But now, elegance emphasizes the ability controlling and balancing life for ordinary people. Elegance is no longer priority.

Bullet comments, that is, real-time (comment) from viewers fly across the screen like bullets while a video is playing.

Bullet chat (be) a commentary system unique to the Bilibili ecosystem, viewers leave comments that scroll across on-screen content.

The human memory is phenomenally strong. It also has a habit of getting things badly wrong. According to Jonathan Hancock, our memory expert, faulty 1  can be extremely revealing (揭露真相的).

Just last week, for example, my wife and I were 2 how we'd chosen our youngest son's name. I had a 3 memory of us writing out a list of possible names, but stopping after just a few because we'd 4 one we both loved.

My wife disagreed. In her memory, we'd had a much 5 list, and gone back and chosen one from the middle of the 6 . But we found that we'd actually done something completely different to 7 Nate's name.

Memory mistakes happen on a larger scale, too. The "Mandela Effect" is when lots of people have confident recollections (回忆) that turn out to be 8 . It was named by researchers who were discussing their strong memories of Nelson Mandela's death in prison — when he actually lived for 23 years after his 9 .

There are plenty of other 10 of this phenomenon. If you're sure that you remember seeing the Monopoly Man wearing a spyglass, for instance, or hearing a wicked queen say "Mirror, mirror on the wall," you've 11 it yourself, but her real meaning "Magic mirror on the wall".

So what's 12 on? Well, for starters, memory often works by association and similar 13 can overlap (部分重叠) in our brains. We're also good at "filling in the blanks" with details that are 14 but untrue. What's more, whenever we run through a memory, we make it stronger, 15 any bits that were wrong.

But there's plenty of good news here, too.

Everyone misremembers. We shouldn't be too hard on ourselves when we 16 mistakes. The mental associations that sometimes lead to errors can also 17 us to find information which is difficult to locate. If you're 18 with someone's name, please try thinking of things you associate with them.

Discussing your memories is great mental exercise. It 19  strengths and weaknesses, and lets you learn tips from others. Besides, remembering is a creative 20 , during which we are also likely to make mistakes. It was certainly true for my wife and me.

Strategies to Overcome Social Phobia (社交恐惧)

Social phobia is an anxiety disorder characterized by intense fear in social situations. People with social phobia feel paralyzing fear when other people are around, as well as nervousness, anguish, or shyness. As we can see, social phobia is very uncomfortable and limiting for the person who suffers from it, so we must differentiate it from shyness.  

Learn to relax. People with social phobia often have what is known as anticipatory anxiety.  For this we have to learn to relax instead of anticipating the fear of the future situation.

Look for social situations.  If we try to relate outside of our usual circle or look for small situations that require a small interaction, we will see how little by little we will feel more comfortable in them. In this way, when a social event arrives that we want to attend or participate in, we will be better able to be comfortable in it.

Make sure your imagination does not betray you. In the vast majority of cases you are afraid of things that have not happened or are not happening. We have to be especially careful what we think others may be thinking of us.

Be yourself. Social phobia is due, in part, to the conviction that we have to be what is expected of us, in giving a perfect image.  So we do not have to focus so much on what others may think of us, but on feeling comfortable with ourselves without having to be perfect.

A. That is, they worry about the situation before it occurs.

B. Imagination can play tricks on us in social situations.

C. We have to learn to accept ourselves and trust ourselves.

D. Be aware of avoiding any situation without overcoming.

E. Next, we are going to see a series of tips to overcome social phobia.

F. If we constantly avoid social situations out of fear, it is very difficult for us to be able to overcome them.

G. If we are able to ask open questions that require more than one "yes" or "no" for an answer and we focus on the answers.

Beautiful coral reefs (珊瑚礁) in Thai seas have been gradually worsening due to global warming that causes coral bleaching, in addition to certain human activities without proper control and environmental consciousness. Recently, researchers from Thai university Chulalongkom have created 3D-printed coral reefs modeled on the nature of real corals called Innovareef to accelerate the recovery of the coral reef ecosystem. 

Innovareef corals are coated with calcium and phosphate nutrients (钙磷营养物) that corals need to thrive and consist of flat surfaces. The reefs' holes serve as habitats and hiding places for many sea animals. Artificial reefs also make use of hydrodynamics technology to enhance their resistance to tidal forces and ensure that they stay in place. Finally, the PH (level of acidity) of the selected type of cement used for the reefs is close to that of seawater, and the design concept is that of Lego, easily assembled (组装) and disassembled blocks that are easy to transport and fix.

"The Innovareef is not too large. It's light-weighted and can be carried by anyone thus saving transportation costs. You can simply put it at any desired location in the sea and then dive down to put all the units together to complete the Innovareef. Not even five minutes afterward, fish and several ocean creatures start to come in to survey and make it their new habitat, leading to biodiversity around the Innovareef. More importantly, the research data indicates that the settlement and growth rates of planula on the Innovareef are better than those on other artificial reefs,"said Associate Professor Dr. Nantarika Chansue at Chulalongkorn University.

Innovareef is the hope for the effective recovery of natural coral reefs. Now the team is focused on adding more details so that the new structures look more like natural reefs. For the future generations of Innovareef, the team will develop a more specific design for each sea species in the area.

On September 26, 2022, NASA successfully completed its Double Asteroid Redirection Test (DART) mission by intentionally crashing an unmanned spacecraft into the asteroid(小行星) Dimorphos. The goal was not to destroy the asteroid but to change its orbit. With the successful mission, NASA proved the concept that this technique could keep a potentially dangerous asteroid from crashing into Earth in the future.

Dimorphos is a small asteroid orbiting the larger asteroid Didymos. NASA noted that Dimorphos is not a threat to Earth, but because it passes relatively close to Earth, it was chosen as the target for the test mission. 

Although the intended crash should change the asteroid's position slightly, it will add to a major shift over time. "If you were going to do this for planetary defense, you would do it 5, 10, 15, or 20 years in advance for this technique to work," said NASA program executive Andrea Riley. "This is why we test. We want to do it now rather than when there's an actual need."

Asteroids can pose a significant threat to planet Earth. For example, around 66 million years ago, an asteroid around 6 to 9 miles across struck the Earth in what is now the Yucatan Peninsula. The resulting impact was so catastrophic(灾难性的) that it caused one of the largest extinction events in Earth's history. Therefore, DART's success is an important step forward in protecting the planet from potential damage from an asteroid. This shows humans are no longer powerless to prevent this type of natural disaster.

The DART spacecraft was launched by NASA on November 24, 2021. It was accompanied by another craft called LICIACube, supplied by the Italian Space Agency, and separated from DART just 15 days before the crash. LICIACube remained in orbit around the asteroid and took photographs of the crash and material ejected(弹出) from the asteroid's surface.

The FIFA World Cup Trophy (奖杯) is arguably one of the most iconic prizes in the sporting world. So far, two different trophies have been used in the history of the FIFA World Cups.

The Jules Rimet Trophy was the first trophy awarded to the winners of the FIFA World Cups. Initially, the old trophy was originally named "Victory". However, this trophy was renamed "the Jules Rimet Trophy" in 1946. This change was made to honor former FIFA president Jules Rimet, who voted to organize the first FIFA World Cup in 1930. French sculptor Abel Lafleur designed the trophy in 1930. The trophy was 14 inches in height and weighed 8.4 pounds. It was comprised of a winged representation of Nike, the Greek Goddess of Victory and was inspired by the Nike of Samothrace statue.

Uruguay became the first champion and kept the trophy in 1930. The trophy was eventually retired when Brazil won the World Cup final for the third time in 1970. Following their success in Mexico, Brazil was allowed to keep the trophy permanently. However, the original trophy was stolen for a second time in 1983. It was never recovered, and it was claimed that it had been melted down into gold bars. Following the retirement of the Jules Rimet Trophy, FIFA needed a new cup. Eventually, Italian artist Silvio Gazzaniga's design was selected as the new World Cup trophy.

The modern FIFA World Cup trophy describes two human figures holding the earth on top of their heads. The base of the trophy has "FIFA World Cup" engraved (刻). Furthermore, following every World Cup, the name of the winning team and the winning year is also engraved at the base. The trophy weighs 13.61 pounds. Unlike the Jules Rimet Trophy, the winning nations and future winners don't get to hold the original trophy anymore. The new regulations state that it remains in FIFA's possession. Instead, winners are given a gold-plated bronze replica (青铜复制品) provided by FIFA.West Germany was the first nation to lift the modern World Cup trophy in 1974.

The new trophy can hold up to seventeen names and years and is likely to be retired following the 2038 World Cup.

China's Cargo Spacecraft Sets New World Record

The Tianzhou 5 cargo spacecraft launched on November 12th docked with the Tiangong space station around noon, setting a world record for the fastest rendezvous and docking operations between the two spacecraft, according to the China Manned Space Agency.

The Tianzhou 5 was placed into a low-Earth orbit by a Long March 7 rocket that blasted off at 10:03 a.m. at the Wenchang Space Launch Center in Hainan Province.

After cargo craft entered the orbit, it traveled two hours and seven minutes to rendezvous (交会对接) with the Tiangong space station and then docked with the massive station at 12:10 p.m., the agency said in a news release.

The maneuvers have become the fastest rendezvous and docking processes for spacecraft, replacing the old record set by the Russian spacecraft Soyuz MS-17 on October 14th, 2020, when it used three hours and three minutes since its liftoff to rendezvous and connect with the International Space Station.

The manned space agency said the fast rendezvous and docking are key to establishing the capability to transport supplies to the space station in an emergency.

My family went on our annual (每年的) summer vacation in a small house on a lake. Every day we kids are busy swimming, fishing and building sand castle on the beach. By the third day of our vacation, however, something caught my attention. I noticed my 10-year-old sister, Kate, always watching videos and looking through online shops indoors. She was so addicted to her cell phone! Over dinner, I asked Kate whether she would like to go hike to the top of the mountain across the lake the following morning, "Maybe you need put your phone away and enjoy the wonderful scenery. It's really amazing. "

"Well," Kate replied unwillingly, "there are some bargains (减价品) tomorrow in several online shops, so I'll not be available tomorrow. "

"You can't miss the fresh air and beautiful views here. Hiking is really fun!"

"I cannot walk so far", she didn't look up from her soup and mumbled (嘟囔), "and it sounds more like punishment than a vacation. "

When I said it only took us half an hour of steady walk to climb to the top, though reluctant, she nodded, "Fine, I'll go. "

The weather was fine as usual with clear skies and gentle winds. After packing, I found Kate walking slowly downstairs and in a very unenthusiastic (不热情的) voice, "Ok, I'm ready to go. Tom"

Anyway, when we stepped out of our house, quite a different view unfolded before our eyes. Sunlight brightened on the glassy surface of the lake. Not far away, a rough path wound to the top of the mountain across the lake with flowers and grass on both sides. We began from the path. 

"Tom, I'm still wondering if it is a good idea to go hiking. " Kate said, frowning (皱眉).

When I lived in China, it was a struggle for me to learn Chinese and adapt to Chinese1 . When I first went to school, I was surprised at the class2 . There were about sixty students in our class. And the students were not so3 as those in the US where we often had open discussions. 

However, it was not a big4 for me because when I went to school, I did not5 anything that the teacher and students said. I6 sat in my seat without7 anything. After I went home, I8 and told my mom that I wanted to go back to my homeland. 

When I calmed down, I9 that I had to study Chinese very hard, but it was very difficult to learn the language. Every day at school, I tried to10 Chinese students and make friends with them. When school was over, I studied Chinese all night using elementary school books. It11 to be a good way for me to learn Chinese. 12 , I began to speak Chinese in school. Finally, I became13 during class and began to make some friends. 14 , I achieved a high grade in the exam and was also able to adapt to Chinese living. 

Now, I like to talk with Chinese friends and I like Chinese food, too. The experience of15 to learn Chinese in China was very valuable for me. I will never forget that time when I learned so much.
