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.

5 . Gyms that profit most from the January rush
Every year, like clockwork, many people go through the same routine. On December 26th and January 1st, as the fog of cheese, chocolate oranges and champagne lifts, regret creeps(悄悄出现)in. Online searches for “get fit” and “lose weight” increase.
Many gym recruits(新成员)will have their new sportswear on for high-intensity interval training. In the basement of Another Space, a club near London’s Leicester Square, music pumps and light flash as a trainer shouts instructions to a group of mostly young women. They are pushed through bursts of burpees, handclap push-ups and various kick and punches at boxing bags. The training is murderous.
They are at one end of a fitness market.
Pure Gym expects soon to reach 1 million members. Part of its appeal is that, unlike traditional gyms, members are not bound by a long contract. “We have taken a £500 decision and turned it into a £20 decision,” says Mr Cobbold.
A.There will be other ripple effects(连锁反应), too. |
B.That will be good news for some gym goers because many will soon suffer a second round of regret. |
C.However, the club’s luxurious changing rooms and bars relieve some of the pain. |
D.Health clubs of all shapes and sizes stand ready to respond. |
E.Spending on fashion items also increases around the time of joining a gym. |
F.At the other are budget gyms, which have accounted for the big part of gym growth in recent years. |

8 . When I was four, I lost my sight by falling off a box car and landing on my head. Now I’m thirty-two. I can vaguely remember the brightness of sunshine and what color red is. It’d be wonderful to see again, but a disaster can do strange things to people.
It took me years to discover and strengthen this belief. It had to start with the most trivial things. Once a man gave me an indoor baseball. “I can’t use this,” I was hurt, thinking he was teasing me. “Take it with you,” he insisted, “and roll it around.” The words stuck in my head. By rolling the ball I could feel where it went.
The hardest lesson I had to learn was to believe in myself. Had I not done that, I’d have broken down and become a chair rocker for the rest of my life. And the path to the belief is never smooth.
A.I’d fail sometimes, but on average, I made progress |
B.This gave me an idea on something I had thought impossible to achieve |
C.As people always say, it takes steel and temper to make a difference |
D.It came into my mind all of a sudden |
E.It occurred to me the other day that I might not have come to love life as I do now if I hadn’t been blind |
F.Life asks a continuous series of adjustments to reality |
