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 (脑内啡）一chemicals in the body that cause happiness 一 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, along with many other chemicals. 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 change. However, when their endocannabinoids were block with a different drug, their runner’s 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 well 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 boost your mood if you have depression, and it's 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 put on our running shoes.

If you ever visit an English village,make sure to look out for morris dancing.Undoubtedly one of the strangest of English culture, morris dancing is a form of folk dancing that dates back to the 15th 15th century.If you ever get the opnortunity,you really have to see it.
Men and women wearing old-fashioned,tattered(褴褛的)clothing dance in the street of towns and villages across the country during the holiday periods. Women wear long，frilly (有 褶皱边的）skirts and men wear short trousers w.th bells attached to them. They dance to traditional folk music which is often played on traditional musical instruments.
Some groups carry heavy black sticks which they bash (击打）against each other while they dance. Other groups wave handkerchiefs in the air whilst they perform. The dances are usually performed near a pub so that when it s over, the dancers and spectators (观众）can sing some traditional folk songs over a pint of beer. The festivities (欢庆）will often continue long into the night, by which point most people are too drunk to think about performing again.
Morris dancing is a great English tradition but it’s facing a big crisis (危机).As the years go by, fewer and fewer young people are joining morris dancing groups. The dancers are getting older and older and eventually, if nothing is done to change this trend, the tradition will die out within the next few decades.
If you’ve ever had the fortune to see morris dancing, you may understand why teenagers aren’t rushing to sign up. Putting it bluntly (直截了当地)，it’s not exactly the coolest thing for an 18-year-old to be doing. Why dress up in bells and funny costumes when you could be going clubbing (逛夜店)？ Or playing sport? Or doing anything else?
However, it would be a great shame to lose such a fun and vibrant (有活力的)part of England’s history and culture. It’s important to look after some traditions and customs especially when it’s something as harmless and happy as morris dancing. So here's a toast to the next generation of would-be morris dancers! Let's hope they don’t leave it too late.

Andreea, 18, from Romania, sent a photograph of the view from her window and included a brief (简短的）apology: “Sorry, this picture is plain and boring. No one would like it.”
At home in New Jersey, US, Coreen Burke, 16, clicked on the same image in her inbox. She saw a village with its old houses, and a distant chimney puffing smoke.
“Isn’t this amazingly different from my country?” she thought to herself.
Burke saw potential in that photo. She posted it to her blog, Outside My Window，which features a daily snapshot (快照）of someone’s window view from different people around the world.
The concept (理念）is simple: We can all relate to the act of staring through a pane of lass (一块玻璃)，onto the scene on the other side,
“Maybe if we understood the way people from all over the world live,” she added, “we would get along better than we have been lately.”
On the sit，Can see Frederic's window in the south of France, looking out on sailboats anchored in a tranquil harbor(宁静的港湾).0r Virginia's view in Canada, a winter scene with trees
laced in white.
Like most high school students, Burke has yet to travel the world. But she hopes to someday collect many stamps in her passport,starting in Greece and India. In the meantime,
however, she's devoting herself to her website.
she posted the first window view from Switzerland, a sunset captured (拍摄）by an 18-year-old.Then others came flowing in by email, up to seven a day, from as far as Kazakhstan and Indonesia.
Contributors are marked on a map on her bedroom wall: A blue dot indicates (表示）their country and a pink dot shows their city, if they provide it. The most responses have come from Europe - Estonia, Poland, Italy, Germany and Sweden, to name a few. She is crossing her Angers that she 11 receive a photo from Africa or Antarctica, which are unrepresented so far.
And while Burke’s become a cyber crusader (斗士）for appreciating the beauty outside our own windows, it will probably come as a surprise to learn that she doesn’t actually have a window in her own bedroom. But with the views out of other people’s she can enjoy whenever she wants to, she surely doesn’t mind.

Hello, boys and girls! Today, I am going to talk about what you should do when a fire alarm go off. If you hear the alarm, stand in line at the door and wait your teacher to lead you outside. Stay close to your teacher and classmates. Don’t panic or get out of line, and try to remain quiet and calmly. Soon the firefighters will come and put out the fire. If it’s a false alarm and there is no fire, your teacher will lead us back to the classroom. If you notice that when someone is missing or hurt, tell your teacher immediately.
