It is a practice favored by Lena Dunham, Tom Hanks and Lady Gaga to improve their focus and bring about calmness in an often busy, distracted world. Now researchers have found evidence that frequent meditation(冥想)over several years, may help change human gut(肠道), boost the body's immune(免疫的)system and reduce the risk of anxiety, depression and heart disease. The findings are published by the British Medical Journal. 

Meditation is increasingly used to help treat drug abuse, overwhelming stress, eating disorders and long-lasting pain. But until now it has not been clear whether it could also be able to change the composition of the gut microbiome(微 生物组). In an effort to find out, researchers led by the Shanghai Mental Health Centre at the Shanghai Jiao Tong University analyzed the stool(粪便)and blood samples of 37 Tibetan Buddhist monks from three temples and 19 residents in the neighboring areas. The Tibetan meditation from the ancient Indian medical system, is a form of psychological training. The monks in the study had practiced it for at least 2 hours a day for 3-30 years. Both groups were matched for age, blood pressure, heart rate and diet. Stool sample analysis revealed significant differences in the diversity and volume of microbes between the monks and their neighbors. "Bacteria enriched in the meditation group had a positive effect on human physical and mental health, "the researchers wrote. "This changed gut microbiome composition could improve immune function in the body. "Blood sample analysis also revealed the levels of markers associated with risk of heart disease were significantly lower in the monks.

The researchers emphasized that the study was observational and the number joining was small, all male and living at high altitude, making it difficult to draw any firm or general conclusions. However, based on their findings, the researchers said the role of meditation in helping to prevent or treat mental and physical illness deserved further research. 

Coined as "deliveryman by day, poet by night, "55-year-old Wang Jibing earns a living as a delivery person in Jiangsu Province. He started writing poems online in the 2000s, and later expanded to different social media platforms. He also came under the spotlight as his name was on the 2023 list of new members for the Chinese Writers Association, igniting(点燃)praise and discussions among Chinese netizens.

Dropping out of secondary school, Wang tried various jobs to make a living, such as a construction worker and working on sand mining boats, as well as a garbage collector. Now as a husband and a father of three children, the financial burden on his shoulder has become heavier and his work schedule has gotten even busier. Yet it has never stopped him from reading and writing routinely all his life. His passion for poetry has driven him to write over 4, 000 poems. 

His poem titled "People in a Hurry" gathered more than 13 million views within a week. Wang gained inspiration for the poem from an unpleasant food delivery experience in 2019. Because the customer made a mistake with the address, he had to rush several times to get the food delivered on time. It led to delays with other orders, as well as punishments and a decrease in his earnings for the delivery. The government later took action to tackle this type of situation, demanding delivery firms better protect delivery person's rights.

The subjects of Wang's poems cover a wide range, including his memories of his family and hometown, and his observations of society and life while working as a laborer in different cities. During an interview with the media, Wang noted that delivering food allows him to interact with more people and experience more things. The job has also sparked a deeper understanding and empathy for others. Writing poetry helps him feel comfortable and find peace of mind. 

In years past, many people would travel over New Year's Eve and immerse(沉浸)themselves in a different culture. Countries around the world celebrate the new year with unique customs and traditions carried out at the celebration. 

Japan: Eat toshikoshi soba

Shiwasu is the end-of-the-year period in Japan. To celebrate New Year's Eve, people eat "year-crossing" soba, which can symbolize having a long and fortunate life along with a clean break from the year. However, when eaten at midnight, there's a certain cross of the old and the new year, thus you cannot "break off" all of last year's troubles properly but instead carry them over to the following year. 

Russia: Burn, then drink your wishes

After a year of ruined dreams and canceled plans, set your sights on a fresh start with this Russian tradition. Before midnight, write down your wishes on a piece of paper, then light the paper on fire. Once it's stopped burning, spread the wish-filled ashes into a glass of champagne and drink up shortly after the clock completes striking midnight. 

Spain: Eat 12 grapes

Perhaps the easiest tradition to carry out is eating grapes for good luck. When the clock starts striking at midnight, eat one with each ringing sound. Better if you're wearing special New Year's Eve underwear while eating your grapes. A pair of red underwear can bring you a new year of love, while yellow may bring joy and fortune. 

Greece: Hang some onions

If you've been cooking throughout the pandemic, maybe you have some onions around the house to spare for this tradition. In Greece, onions symbolize rebirth, so people hang them up on their doors on Dec. 31 to encourage a year of growth. Keep the Greek traditions going by baking a special cake on New Year's Day. Hide a coin in the cake and share it with your loved ones-whoever finds the coin is said to have a year of good luck.

How many time do you spend with your parents? Your parents are your dearer people in the world when you are young. And they always care for you deep. But even though many children still loves their mum and dad, families may become less close as you get older. The end of the year is a time for families to got together. Have you ever thought of how you can show your parents that you love them? Find a chances and do something for them or have sincere talk with them. What you can do this, your parents will be very happy.

I attended a birthday party in 1991. My teacher was then 59 years old.  her fellow teacher said that we (celebrate) her 39th birthday! We were all  (surprise) and puzzled.

After the party I was told by the fellow teacher that American women have a special saying about (birth). If a woman is over 40, or even if she is 80, her birthday is always 39th. If she is in her thirties, her birthday will be the 29th. And in her twenties, it's the 19th. They usually have (they) "real" birthday when they are 20. This shows that American women, (special) elderly women, are very sensitive about their ages. But my teacher always says, "We want to be (young). " so about the age of Western women, my advice is  if you don't know it, don't ask about it; if you really know it, don't mention it.

Perhaps you have heard the expression "When in Rome, do as the Romans do". So when you want to do business in France, you have to get to know French culture, make marketing plans, and run your business by local laws.

The French take great pride in their language, so anyone who does not speak it may run the risk of being disrespected by his French colleagues or business partners. Also, another reason why learning French is important is that it is a great way to show every possible French business partner that you care and respect their country's culture and language.

The first thing that you should do when meeting someone new is to shake his hand firmly and always look at the person in the eye. In social meetings with friends, kissing is common.

Use first names only after being invited toThe French will sometimes introduce themselves using their surname first, followed by their first name.

Dress wellYour business clothing is a reflection of your success and social status. Always try to be tasteful and stylish. Women are advised to dress simply but elegantly. Wearing make-up is practiced widely by businesswomen.

The French are passionate about food, so lunches are common in doing business in France, which usually consist of an appetizer, main meal with wine, cheese, dessert and coffee, and normally take up to two hours.

Imagine you're standing in line to buy a snack at a store. You step up to the counter and the cashier scans your food. Next , you have to pay, but instead of scanning a QR Code(二维码) with your smart phone, you just hold out your hand so the cashier can scan your fingerprint. Or, a camera scans your face, your eyes or even your car.

Now, this type of technology might not be fa r away. As technology companies move away from the traditional password, biometric(生物特征识别的) security, which includes fingerprint, face and voice ID, is becoming increasingly popular.

In 2013, Apple introduced the iPhone 5s, one of the first smart phones with a fingerprint scanner. Since then,using one's fingerprint to unlock a phone and make mobile payments has become commonplace, bringing convenience to our lives . And since 2016, Samsung has featured eye-scanning technology in its top smart phones.while Apple's new iphone X can even scan a user's face. But despite its popularity, experts warn that biometries might not be as secure as we imagine."Biometries is ideally good in practice, not so much, "said John Michener,a biometries expert.

When introducing the new iPhone's face ID feature, Phil Schiller, Apple's senior vice-president, said."The chance that a random person in the population could look at your iPhones X and unlock it with their face is about one in a million' But it's already been done. In a video posted on a community website Read fit, two brothers showed how they were each able to unlock the same iPhone X gunning their own face. And they aren't even twins.

"We may expect too much from biometries," Anil Jain, a computer science profess or at Michigan State University , told CBS News."No security systems are perfect."

Earlier last year, Jain found a way to trick biometric security. Using a printed copy of a thumbprint, she was able to unlock a dead person's smart phone for the police, according to a tech website Splister."It's good to see biometrica being used more," Jain told CBS News,"because it adds another factor for security. But using multiple security measures is the best defense."

Circles can be found everywhere in the natural world, but with no accurate way to meas.ure them they are very mysterious and might never be fully understood. When you take the distance around a circle and divide it by the distance across a circle, you will always get Pi(m). While Pi is equal to about 3.14 when rounded, it is infinitely long. With the help of computers, mathematicians have been able to calculate Pi out to over a trillion decimal(小数)places. This makes Pi puzzling, even to the most famous mathematicians.

Pi Day is celebrated globally on March 14, since the way we write this date, 3/14, looks just like Pi when rounded. In 2009. U. S. Congress voted to officially make March 14 Pi Day.Certain parts of the world——places where March 14 is written as 14/3—will instead celebrate Pi Approximation Day which takes place on July 22nd because of the result of 22/7.

Pi has appeared in movies, comics, music, and more. "In modern movies, any time the filmmaker wants to create a sense of mystery, the symbol Pi is used,"says Blatner, People also love working to memorize the digits(数位) of Pi and competing against others to see who can remember most. The Guinness World Record for reciting the most digits of PV is held by Lu Chao of China, who successfully recited Pi to nearly 67.000 decimal places.

Above all, Pi Day is about having fun with the number, according to Blatner. People will celebrate Pi Day by eating pie and throwing pie, and with fun Pi-related games. Princeton,New Jersey holds a series of Pi-related festivities. Events this year include a surprise birthday party for Albert Einstein whose birthday also falls on March 14, and a "Walk a Pi Event"where participants will walk 3.14 miles together. Just like the number itself, the possibilities for Pi Day are truly endless.
