Runners need to move 15 per cent faster on a treadmill(跑步机) to burn the same number of calories as jogging outdoors, research reveals.
Researchers from Milan University analyzed the difference between running outdoors and on a treadmill in 15 physically fit males with an average age of 21. The participants completed a sprint(短距离快速跑) for 30 seconds followed by 30 seconds of recovery for a total of 15 minutes both outdoors and on a treadmill. Oxygen use and exercise intensity were measured after both types of running.
The findings were published in the journal of Applied Physiology, Nutrition and Metabolism. Results revealed that when on a treadmill, runners use significantly lower amounts of oxygen, suggesting less effort is required. Therefore runners must move 15 percent faster on a treadmill to burn the same amount of calories as exercising outdoors, the study stated. The study authors wrote, "A 15 per cent increase in running speed during a period of stopping and starting often in high intensity treadmill training session is the best possible solution to reaching the same physiological responses as an outdoor training session.
Although the study did not speculate why treadmill running appears to be needing less effort and energy, previous research suggests the moving belt of a treadmill moves joggers forward, causing them to move faster. Exercising indoors also means gym-goers do not have to fight with steep hills or wind resistance.
Michael Silverman, director of rehabilitation and wellness(康复科) at Northern Westchester Hospital in New York, said, “Outdoors, you are changing surfaces constantly, fighting the wind, and making quick and sudden starts and stops, which will lead to increased caloric burn.” Shake magazine reported. "And while we don't recommend running in extreme temperatures, it is worth noting that your body burns extra calories to regulate your body temperature," he says.

Salvador Dali (1904—1989) was one of the most popular of modern artists. The Pompidou Centre in Paris is showing its respect and admiration for the artist and his powerful personality with an exhibition bringing together over 200 paintings, sculptures, drawings and more. Among the works and masterworks on exhibition the visitor will find the best pieces, most importantly The Persistence of Memory. There is also L’Enigme sans Fin from 1938, works on paper, objects, and projects for stage and screen and selected parts from television programmes reflecting the artist’s showman qualities.
The visitor will enter the World of Dali through an egg and is met with the beginning, the world of birth. The exhibition follows a path of time and subject with the visitor exiting through the brain.
The exhibition shows how Dali draws the viewer between two infinities (无限). ＂From the infinity small to the infinity large, contraction and expansion coming in and out of focus: amazing Flemish accuracy and the showy Baroque of old painting that he used in his museum-theatre in Figueras,＂ explains the Pompidou Centre.
The fine selection of the major works was done in close collaboration (合作) with the Museo Nacional Reina Sofia in Madrid, Spain, and with contributions from other institutions like the Salvador Dali Museum in St. Petersburg.

Papa, as a son of a dirt-poor farmer, left school early and went to work in a factory, for education was for the rich then. So, the world became his school. With great interest, he read everything he could lay his hands on, listened to the town elders and learned about the world beyond his tiny hometown.“There’s so much to learn,” he’d say. “Though we’re born stupid, only the stupid remain that way.” He was determined that none of his children would be denied (拒绝) an education.
Thus, Papa insisted that we learn at least one new thing each day. Though, as children, we thought this was crazy, it would never have occurred to us to deny Papa a request. And dinner time seemed perfect for sharing what we had learned. We would talk about the news of the day; no matter how insignificant, it was never taken lightly. Papa would listen carefully and was ready with some comment, always to the point.
Then came the moment—the time to share the day’s new learning.
Papa, at the head of the table, would push back his chair and pour a glass of red wine, ready to listen.
“Felice,” he’d say, “tell me what you learned today.”
“I learned that the population of Nepal is ....”
Silence.
Papa was thinking about what was said, as if the salvation of the world would depend upon it. “The population of Nepal. Hmm. Well….” he’d say. “Get the map; let’s see where Nepal is.” And the whole family went on a search for Nepal.
This same experience was repeated until each family member had a turn. Dinner ended only after we had a clear understanding of at least half a dozen such facts.
As children, we thought very little about these educational wonders. Our family, however, was growing together, sharing experiences and participating in one another’s education. And by looking at us, listening to us, respecting our input, affirming our value, giving us a sense of dignity, Papa was unquestionably our most influential teacher.
Later during my training as a future teacher, I studied with some of the most famous educators. They were imparting what Papa had known all along—the value of continual learning. His technique has served me well all my life. Not a single day has been wasted, though I can never tell when knowing the population of Nepal might prove useful.

My color television has given me nothing but a headache. I was able to buy it a little over a year ago because I had my relatives give me money for my birthday instead of a lot of clothes that wouldn’t fit. I let a salesclerk fool me into buying a discontinued model. I realized this a day later, when I saw newspaper advertisements for the set at seventy-five dollars less than I had paid. The set worked so beautifully when I first got it home that I would keep it on until stations signed off for the night. Fortunately, I didn’t got any channels showing all-night movies or I would never have gotten to bed.
Then I started developing a problem with the set that involved static (静电) noise. For some reason, when certain shows switched into a commercial, a loud noise would sound for a few seconds. Gradually, this noise began to appear during a show, and to get rid of it. I had to change to another channel and then change it back. Sometimes this technique would not work, and I had to pick up the set and shake it to remove the sound. I actually began to build up my arm muscles (肌肉) shaking my set.
When neither of these methods removed the static noise, I would sit helplessly and wait for the noise to go away. At last I ended up hitting the set with my fist, and it stopped working altogether. My trip to the repair shop cost me $62, and the set is working well now, but I keep expecting more trouble.

When her five daughters were young, Helene An always told them that there was strength in unity (团结). To show this, she held up one chopstick, representing oneperson. Then she easily broke it into two pieces. Next, she tied several chopsticks together, representing a family. She showed the girls it was hard to break the tied chopsticks. This lesson about family unity stayed with the daughters as they grew up.
Helene An and her family own a large restaurant business in California. However, when Helene and her husband Danny left their home in Vietnam in 1975, they didn't have much money. They moved their family to San Francisco. There they joined Danny's mother, Diana, who owned a small Italian sandwich shop. Soon afterwards, Helene and Diana changed the sandwich shop into a small Vietnamese restaurant. The five daughters helped in the restaurant when they were young. However, Helene did not want her daughters to always work in the family business because she thought it was too hard.
Eventually the girls all graduated from college and went away to work for themselves, but one by one, the daughters returned to work in the family business. They opened new restaurants in San Francisco and Los Angeles. Even though family members sometimes disagreed with each other, they worked together to make the business successful. Daughter Elisabeth explains, "Our mother taught us that to succeed we must have unity, and to have unity we must have peace. Without the strength of the family, there is no business."
Their expanding business became a large corporation in 1996, with three generations of Ans working together. Now the Ans' corporation makes more than $20 million each year. Although they began with a small restaurant, they had big dreams, and they worked together. Now they are a big success.
