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.

When Yi Xiaoyang was two, he fell in love with skiing (滑雪). His first time on snow, however, wasn’t successful. He slept on the ski lift until the coach found him. He started to learn how to ski from then on. Yi was a fast learner, and at the age of six, he began to ski in other parts of the world.

Luckily, during that break, he picked up his joy in skiing. “I found that skiing had already become one important part of me, ” said Yi. After that, he moved back on his fight for his dreams.

5 . Growing up in the small town of Palmerston, Ontario, I had a dream: to work in television. However, it sounded like a dream that could never come true.
Thankfully, my parents had raised me to have a lot of confidence. With their help and encouragement, I applied to the radio and television arts program at Ryerson in Toronto. After graduating, I worked for Bell Canada for a while, writing and producing commercials. I soon decided, however, that what I really wanted was to be on camera.
I went to the CBC and CTV and applied for a job. They both turned me down because I didn’t have any experience. Luckily, Global Television had just started broadcasting in Canada that year. I found out the president was named Mr. Slaight and called him. I said, “I’ve heard that your studio facilities are amazing. I could come at eleven o’clock on Tuesday or eleven o’clock on Wednesday for a tour. What would suit you better?” He stuttered a bit, then picked a day. When I hung up, I was scared but ecstatic.
On the appointed day, I arrived at the studio. When we sat down, he looked at me and said, “What do you want?” He sounded a little angry and frustrated — but very curious. “All I want is a chance,” I said. “If something on camera comes up at Global — I don’t care what — I want a chance to audition. That’s all I’m asking.”
Three months later, his secretary called and asked me to audition for a new game show. When I arrived at the station, I went right into an audition for a new show called Wintario. The following day, I was handed an airline ticket to Sault Ste. Marie to do the very first Wintario show.
From Wintario, everything happened for me. I hosted the National Santa Claus Parade for fifteen years. I did hundreds of television commercials, a number of movies, training videos, and travel shows. And everything came from finding the courage back in 1975 to make that one phone call.

9 . The elderly residents (居民) in care homes in London are being given hens to look after to stop them feeling lonely.
The project was dreamed up by a local charity (慈善组织) to reduce loneliness and improve elderly people’s wellbeing. It is also being used to help patients suffering dementia, a serious illness of the mind. Staff in care homes have reported a reduction in the use of medicine where hens are in use.
Among those taking part in the project is 80-year-old Ruth Xavier. She said: “I used to keep hens when I was younger and had to prepare their breakfast each morning before I went to school. ”
“I like the project a lot. I am down there in my wheelchair in the morning letting the hens out and down there again at night to see they’ve gone to bed.”
“It’s good to have a different focus. People have been bringing their children in to see the hens and residents come and sit outside to watch them. I’m enjoying the creative activities, and it feels great to have done something useful.”
There are now 700 elderly people looking after hens in 20 care homes in the North East, and the charity has been given financial support to roll it out countrywide.
Wendy Wilson, extra care manager at 60 Penfold Street, one of the first to embark on the project, said: “Residents really welcome the idea of the project and the creative sessions. We are looking forward to the benefits and fun the project can bring to people here.”
Lynn Lewis, director of Notting Hill Pathways, said: “We are happy to be taking part in the project. It will really help connect our residents through a shared interest and creative activities.”
