1 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

Hi, everyone.
Traditionally,
Of course, the events of 2020 haven’t shown a lot of respect for our traditions. In a year of so much tragedy, it can be tough to give thanks when you’re doing your best to get by. And far too many of us will have to gather around a table with an empty chair, if we were able to gather together at all.
One thing, though, we can say about 2020 is that it forced us all to cherish what is most important, what’s most meaningful in our lives. To stop taking things for granted,
Throughout this challenging year, I’ve been moved, again and again, by the sacrifices so many were willing to make on behalf of others. The healthcare professionals who risked their lives to save ours. The workers who have kept our lights on and our shelves stocked, always essential to our economy, but finally
These are exactly the leaders Michelle and I started our Foundation to support. We always thought they
What we learned in 2020 is that these emerging leaders aren’t just building a brighter future, they’re safeguarding our present. In hard times, they are the ones who’ve given me solace. It’s
Merry Christmas and Happy Holidays, everybody.
—Quoted from Barack Obama’s Christmas speech in 2020

Why true happiness isn't about being happy all the time
Over the past two decades, the positive psychology movement has brightened up psychological rescarch with its science of happiness and human potential. It argues that psychologists should not only investigate mental illness but also what makes life worth living.
The founding father of positive psychology, Martin Seligman, describes happiness as experiencing frequent positive emotions, such as joy, excitement and satisfaction, combined with deeper feelings of meaning and purpose. It implies a positive attitude in the present and an optimistic outlook for the future. Importantly, happiness experts have argued that happiness is not a stable ,unchangeable feature but something flexible that we can work on and eventually strive towards.
Recent research indicates that psychological flexibility is the key to greater happiness and well-being.For example,being open to emotional experiences and the ability to endure periods of discomfort can allow us to move towards a richer, more meaningful existence. Studies have also demonstrated that the way we respond to the circumstances of our lives has more influence on our happiness than the events themselves. Experiencing stress, sadness and anxiety in the short term doesn't mean we can't be happy in the long term. Putting up with sorrow can make us tougher and lead us to take action in our lives, such as changing jobs or overcoming hardship. Often when people have faced difficulty, illness or loss, they describe their lives as happier and more meaningful as a result.
Unlike feeling happy, which is a temporary state, leading a happier life is about individual growth through finding meaning. It is about accepting our humanity with all its ups and downs, enjoying the positive emotions, and making use of painful feelings in order to reach our full potential.

National governments neglecting development needs of cities
National governments around the world are neglecting the needs of their major cities with non-existent or inadequate development policies, a new report has found. National governments are key to making cities more sustainable, because cities are limited distinctly in the policy measures they can take for themselves, the report points out. However, only a quarter of the world’s governments have urban development policies at all, and most of those that do exist are far from

One of the greatest stories of rags to riches success is that of Andrew Carnegie, who started life in poverty but became the richest man in the world.
Carnegie was born in Scotland in 1837, the son of a weaver. In 1848, the family moved to the United States and at 13 Carnegie began work in a cotton mill, earning $1.5 per week. About three years later, he found a better job as a telegraph messenger boy. At work, his superiors (上级) were

The lost art of listening
Do you think you’re a good listener? Chances are that you do. But studies show that most people seriously overestimate their ability to listen. The truth is we are generally not good at listening, and our listening comprehension declines as we age.
This was proven by Dr. Ralph Nichols, who conducted a simple experiment to test students’ listening skills. He had some Minnesota teachers stop what they were doing mid-class, and then asked students to describe what their teachers had been talking about. While older kids with more developed brains, are usually assumed to be better listeners, the results, however, showed otherwise: While 90 percent of first-and second-graders gave correct responses, this percentage dropped rapidly as the students got older.
One reason for our poor listening concerns the speed at which we think. The adult brain can process up to around 400 words per minute, more than three times faster than the speed an average person speaks. This means we can easily think about something else while someone is talking to us, allowing our mind to wander or get sidetracked. The younger students in Dr. Nichols’s experiment were better listeners partly because their brains were less developed — they lacked the extra brain power to be distracted.
Another factor that contributes to our poor listening is our ever-decreasing attention span. According to a Mircrosoft study, the age of smartphones has had a negative impact here. In 2000 — around the time the mobile revolution began — the average human attention span was 12 seconds; by 2013, it had fallen to 8 seconds. Even a goldfish — with an average attention span of 9 seconds — can hold a thought for longer!
More and more people now realize that listening is a skill that can be developed through practice. Learning to observe a speaker’s body language and emotions, for example, can improve our active listening. Even the simple act of note-taking or making eye contact can help us stay focused while listening.
Animated movies use drawings instead of real people. Artists must draw thousands of pictures and each picture must be a little different. For example, if the movie-maker wants to show a girl running, the artist must draw her feet in different places in each picture. When the pictures are shown very quickly, one after the other, it looks like the girl is running. Walt Disney was not the first or only person to use animation in movies, but he is the most renowned. His first Mickey Mouse cartoon, produced in 1927, was called Plane Crazy. This was a short, silent movie about the adventures of a little mouse.
Many people in the movie business thought that animation was only appropriate for short cartoons. Disney did not agree with them. He believed that he could tell any kind of story using animation. His first long movie was Snow White and the Seven Dwarfs. Disney spent all his money making this movie. Fortunately, it was a great success. He made Pinocchio next and then Dumbo (about a baby elephant), and he didn’t look back after this.
When we think of Disney, however, we don’t only think of movies, we also think of Disneyland. There are Disneylands in Japan, the United States of America and France. They are large parks where people can meet Disney’s characters and visit scenes from his movies.
Although Walt Disney made many of the famous movies many years ago, they are as popular now as they were when he made them. Today we can buy them on video and see them in movie theatres from time to time. When Walt Disney began making his animated cartoons all those years ago, people drew all the pictures by hand. Nowadays computers do much of his work.
