Most schools ban chewing gum, but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help boost your test scores.
This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath. Many studies have shown that chewing gum after meals can stimulate the production of saliva (唾液). Saliva helps wash away bacteria (细菌) that damage our teeth.
Nutritionist Gil Leveille, executive director of the Wrigley Science Institute, says that chewing gum might also be good for your brain. One Japanese study of nine participants, found that chewing gum boosted the flow of blood to participants’ brains by up to 40 percent. Blood carries oxygen, which fuels brain cells.
Other small studies have found that people perform better on memory tests while chewing gum. And a study in the United Kingdom found that people who chewed gum while memorizing a list of words did about 25 percent better at recalling those words than people who didn’t chew gum.
“It certainly makes sense,” Leveille says, “that increased blood flow would be related to increased alertness.”
“Additional studies, with longer follow-up, are needed to confirm that chewing gum has benefits, ”he adds. So far, results of studies about memory have been mixed. What’s more, many of the studies that show gum’s benefits are funded by gum companies. “Too much chewing can damage the jaw joint,” warns Gayl Canfield, a researcher at the Pritikin Longevity Centre. “What’s more, no matter how healthy gum chewing proves to be,” she adds, “it will never be a match for a healthy lifestyle.”

【推荐2】How to deal with stress
Stress is a negative reaction that the body has to various factors and events. It is often caused by poor health and then leads to various health problems. However, frequent emotional stresses may cause chronic (慢性的) stress.
Introduce sports into your life.
If you are often stressed and not exercising, this is the very sign to start exercising.
Not many people are able to completely give up a cup of coffee in the morning or a glass of wine after a long day at work, but everything should be taken properly. Get rid of the habit of drinking coffee several times a day and drinking a bit too much with friends at every given opportunity — the result will change your mental and physical state in countless ways.
Observe your sleep patterns.
If flowing a good seeping schedule makes it so easy to avoid stress, then why do so few people do it? It’s simple: people often think they are in good condition and if they manage to get through the day with minimal seep they will repeat this unhealthy behavior. Get into the habit of waking up and going to bed at almost the same time, leaving you feeling well-rested and balanced for the day ahead.

A.Drink less alcohol and coffee. |
B.Make time for yourself every day. |

【推荐3】One in four of us at some point will experience mental health problems. It is therefore not only possible, but probable that either you or someone will struggle with your mental health at some point in your life.
Insight, honesty and denial are arguably the biggest barrier that persons must overcome. Before you can have an honest, and transparent conversation with your boss, you need to have that conversation with yourself. Unfortunately, despite progress over recent years in reducing mental health related stigma (羞耻) online, the reality is that stigma continues to thrive. Moreover, far too many of us continue to internalize (内在化) that stigma and direct it towards ourselves.
We need to accept that we might be struggling with our mental health and that work might be contributing to this. We need to educate ourselves about what the signs are of common mental disorders. Are you feeling more depressed or low in mood than usual?
A.Are you not enjoying life as much as you used to? |
B.You can discuss how this is affecting you personally. |
C.Do you tend to make new friends in an unfamiliar environment? |
D.Investigate what your employer’s approach to health is more generally. |
E.Consequently, we might be ashamed, or deny our work is affecting our mental health. |
F.I suggest you arrange to meet with your boss again to explore deeper into some topics. |

【推荐1】Feeling a bit bored? It could be just what you need to produce your best ideas, excite your creativity or simply give your brain a rest.
Nowadays, in the age of round-the-clock entertainment, it’s (technically) trickier to be bored. If the show you’re watching has lost its spark, you can easily amuse yourself on social media without even leaving the sofa. But that’s not necessarily a good thing. Feeling disengaged from the task in hand, or a lack of stimulation (刺激), does have its benefits, according to researchers at the University of Central Lancashire.
Being bored motivates you to search out something less boring to do. For example, if you decide there’s nothing worth watching on TV, you might choose to switch off and take up a new hobby. This, according to researchers, can explain why the lockdowns of the past two years saw a surge (激增) in creativity among people stuck at home from banana-bread-making to picking up a paintbrush for the first time since childhood.
But what about those times when you have no choice but to stick with the boring situation, waiting for a bus, for instance? The good news is that the boredom you’re feeling now could spark your creativity later, says a 2019 study published in the Academy of Management Discoveries journal. People who’d taken part in a bean-sorting task later performed better at coming up with creative ideas than another group who’d been given something more interesting to do first.
Ultimately, don’t take it for granted that there’ll always be something close at hand to entertain us. With boredom, we will not run the risk of becoming boring ourselves.

【推荐2】Does your local town have a nickname? If so, what does it say about the area and the people who live there?
Many cities are recognized across the world by their unofficial titles. New York is the Big Apple. London is the Big Smoke, and Los Angeles is famously called La La Land.
Now Britain's National Mapping Agency(规划局), Ordnance Survey, and the British Linguistics (语言学)Charity, the English Project, are launching an interactive project to uncover the nicknames people use for local places.
The project, which was launched last week to coincide with English Language Day, is called Location Lingo. It aims to identify the names people use every day, whether it's a term of endearment(昵称) or a hate name.
The University of Winchester's Professor Bill Lucas is a leader of the English Project.He explains that unofficial place names often show what people think about a place.“The name that people conjure up or create for a place forms an emotional connection, ”he says, “So Basingstoke becomes Amazingstoke, Swindon is known as Swindump. Padstow, hometown of chef Rick Stein, is nicknamed Padstein.”
Basingstoke is a town in central England. The local nickname, Amazingstoke, shows the love that locals seem to have for the area. Swindon, on the other hand, is sometimes called Swindump, showing that local people think it's a big dump. Stanford Le Hope in Essex is called Stanford No Hope by locals. And Padstow in Cornwall is so closely associated with the local celebrity Rick Stein that it's become known as Padstein.
Since launching the online database (数据库) last week, the creators have already received 3,000 alternative titles for places and landmarks.
Some also say that the project could even have a practical use. Glen Hart, Ordnance Survey's head of research, says the information could be very helpful to the emergency services, for example. “By having the most complete set of nicknames, we could help the emergency services quickly locate the right place, and maybe even save lives, ”he says.

【推荐3】Did you know many adults sit down for more than nine hours a day? Maybe you’re one of them! Whether it’s working at a desk, sitting motionless in a car, bus or train or lounging on the sofa watching TV, we have a much more sedentary lifestyle than our parents and grandparents did. The question that this raises is just what it is doing to our bodies.
The news isn’t good. A study carried out in the 1950s compared bus drivers with the conductors, who walked around the bus selling tickets. It showed that drivers, who spent many hours sitting at the wheel, were twice as likely to have heart attacks than the more active conductors. In fact, prolonged sitting has been associated with a number of different conditions, even in people who otherwise take regular exercise. If you sit down all day, you burn far fewer calories than someone with a more active job. There are suggestions that its lows your metabolism (新陈代谢) and makes it harder for your body to regulate blood sugar levels increasing the risk of diabetes.
One possible answer to this problem is for desk workers to use standing desks, to spend at least part of their day on their feet. One small study showed that office workers who stood for three hours after lunch had a much smaller increase in blood sugar levels, while another suggested that by standing for three or four hours a day over the period of a year, people would burn as many calories as if they had run ten marathons.
Other experts question this figure and point out that standing all day can also have negative impacts, such as leg or back pain, recommending that if people do want to use standing desks, they should gradually increase the amount of time that they spend on their feet. Crucially, they also point out that there are many alternatives to sitting, and that their impact is unlikely to be the same; walking, for example, burns far more calories than standing.

【推荐1】In the city of Midland, Michigan in the United States sits the Charles, W. Howard(CWH)Santa Claus School. This is not a school that children attend to learn grammar and fractions but one that adults travel to once a year. There, they learn how to play the role of Santa Claus.
For better or worse, Christmas is a profitable business in the modern world, particularly in the US. Therefore, during winter, thousands of people are hired by businesses to put on Santa’s famous red cloak, red hat, and white beard. These Santas will appear at public spaces, where starry-eyed children sit on their knees and dreamily recite their lists of all the wonderful Christmas gifts they desire.
Given this demand, the CWH Santa Claus School is dedicated to training adults to be the best Santa Claus they can be. Started by Charles Howard himself in New York in 1937, the school has a mission to uphold the traditional image and preserve the history of Santa Claus. Meanwhile, it also teaches students how to incorporate their personalities into the role. The school was relocated to a new place in Midland by its current manager, Tom Valent, in 1986. It now offers a three-day crash course every October for aspiring Santa Clauses to learn under the guidance of Valent and other instructors. The curriculum (课程) includes such content as singing, toy production, and even reindeer care.
The CWH Santa School is called the “Harvard of Santa schools”. In addition to being a family-run operation, it recruits (招募) Santa teachers from all over the world to hand down knowledge about how to be the very best Santa Claus.

Neophobia is common in children; it often happens at the dinner table. Some children just refuse to try new food because they don’t know what it will taste like, while others dislike new food before even smelling it. Some children take it to the extreme(极端) and will only eat a few foods that they like. Psychologist Dr. Elizabeth Capaldi says that, by the time children reach the age of two, they have formed their own eating habits that they don’t want to be disturbed by new offerings at the table.
A newly published study led by Dr. Lucy Cooke of University College London showed that picky eating in children results from genetic(遗传的) and environmental causes. The research, which followed the eating habits of 5,390 pairs of twins between the ages of 8 and 11, found that about 75% of the neophobia in the children was from their parents, while 25% was due to the influence of environment.
Children grow at a high speed during their first year, but that fast-paced growth tends to slow down by their second year. When children are not experiencing one of those fast growth periods, their body needs less energy; and that results in a smaller appetite(胃口). When children are not hungry, they tend to enjoy only food they like. They refuse new food and food that is not their favourite. Some children will limit the amount of food to only one kind, like hamburgers or pancakes, leaving all the other foods untouched.
In some cases, many real reasons why a child behaves as a picky eater exist. About 5% of children who are 10 years of age or younger have some type of neurological dysfunction(神经机能障碍) that influences their eating habits. These children may be easily hurt by some special smells, or their brain may not be able to process such sensory information properly.

【推荐3】When the first women to be admitted to Y ale arrived on campus 50 years ago,it had little idea how to support them at a place that was the oldest all-male college in the country.
Sixty-five percent of them had a class in which they were the only woman,according to an unpublished survey,conducted this year,of nearly half of the 575 female freshmen who entered Yale in 1969.Women weren’t permitted to have lunch at Mory’s,a dining club where important meetings took place.They were kept from most after-class activities.
Yale had been set up to educate“1,000 male leaders”and male students were selected on the basis of their future leadership.But women weren’t expected to be leaders.Instead,they were mainly evaluated(评估)on grit.
“It is a kind of determination,a pioneer quality,”Henry Chauncey,one of the Yale teachers,told The New York Times in 1969,“How to find the gritty women?Admit those who were raised with brothers—the more the better!”
“We had grit.But that doesn’t mean it wasn’t challenging because Yale wasn’t entirely prepared for us,”said Sally Birdsall,who was the only female in the economy class.She remembers that a professor warned her that he did not want to hear knitting needles(织针)in his class.
“I was upset,not because I had a knitting needle,but I was more scared,”she said.“It just gave me a very unwelcome feeling.”
In their post-college achievements,they were unusual among American women of their age,and faced challenges that have become familiar to highly educated women today:how to achieve educational,job and family goals when they’re all running on the same clock with men.
Eighty-two percent of the surveyed women had children,and their average age of first birth was 33.The national average at the time was 21.
Their experiences show how much has changed in 50 years—and how much has not.
