2 . 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.

3 . When the leaves begin to change their colors and the birds head south, we know the season is starting to change. On September 7 comes White Dew (白露), the 15th solar term (节气) of the year. It indicates the beginning of the cool autumn. As the temperature falls, white dew is often seen on the grass and trees at night.
For writers and poets, autumn is a difficult season to describe. It’s the end of the summer, and therefore a little sad. The days seem to get shorter, and when you wake in the morning, there’s mist (薄雾) and it’s cooler. Winter is just around the corner.
American writer Ernest Hemingway wrote in his book A Moveable Feast (《流动的盛宴》), “You expected to be sad in the fall. Part of you died each year when the leaves fell from the trees and their branches were bare against the wind and the cold, wintry light. ”
But on the other hand, autumn has its good side. There are so many changes at this time of year, such as the colorful leaves and cooler nights. French writer Albert Camus even thought autumn was a second spring, “when every leaf is a flower.” This view is also found in the most famous autumn poem in English literature, To Autumn by John Keats. In that poem, Keats says that autumn has its own songs, just like spring.
Another theme of this season is wisdom. The arrival of autumn is thought to be similar to a person becoming mature (成熟的).
The great Irish poet W.B. Yeats used this idea in his poem The Wild Swans at Coole (《库尔的野天鹅》), writing about the changing seasons in Coole Park in the west of Ireland. Seeing and counting 59 swans, he remembers first making the count as a young man. Seeing the swans do the same thing for all those years, he’s reminded that even though we get older, our hearts always stay the same age.
