Sitting around doing nothing used to seem like one of the safest activities possible. Then a few years ago scientists discovered that sitting all clay causes harmful changes that increase your chances of meeting an early end. Even regular workouts didn't fix the ill effects of having your bottom in a chair all workday. Suddenly, sitting became public health enemy number one. However, a new research finds that tiny bursts of intense activity are enough to protect your body from the worst effects of your couch-bound lifestyle.
In the research, the scientists closely observed eight young, healthy volunteers as they sat around. On the first day of the experiment they simply lounged for six hours. On the second day they got up every hour and engaged in five rounds of four seconds of intense workouts on a specialized bike.
"Twenty seconds total exercise an hour sounds like nothing, but the data showed it made a big difference to the subjects' bodies. In short, they didn't exhibit the usual ill effects of having sat all day. This study is small, but it's still both hopeful and relevant. The results suggest that breaking up sitting with frequent exercise can undo some of the effects of being inactive," explains Gretchen Reynolds.
"While the study used a special type of bike developed by sports scientists, the researchers feel similar results are obtainable with home exercise equipment. However, you may have to work for a few more seconds to reach the same level of intensity. You should try to get your heart pumping to its maximum as quickly as possible to ensure the effect. When you find yourself sitting for most of the day, try to rise frequently and move as often during the day as possible and for as many seconds as you can manage," Reynolds concludes.

【推荐2】Winter-swimming has become popular in Beijing. Three years ago, few people would go swimming in the city waters. But now there is a Winter-swimming Enthusiasts’ Club(冬泳爱好者协会) and it has more than 2, 000 members. The oldest is 84 years of age and the youngest is only 7. The members are from all ways of life. They may be workers, peasants, soldiers, teachers, students....
Though it is now the coldest part of the season and the water temperature in the city’s lakes is around 0°C, many winter-swimmers still swim in the icy waters, even when it is snowing. They enjoy themselves in the lake, while the people by the side of the lake are wearing heavy clothes.
Why are so many people interested in winter-swimming? Because winter-swimming can be good for one’s health.
Bei Sha is a good example. He is 69 years old, and he once suffered from heart trouble for 26 years. After ten years of winter-swimming he is now in good health. Scientists are now studying the effects of winter-swimming on health.

【推荐1】Forming a new habit in the best of times can be difficult, let alone trying to make changes when you’re already spent. So what do you do if you find yourself exhausted but longing for a change? Here is the pathway to sustainably building new habits.
Start with Sleep
If you’re super tired, then the key to greater productivity is to get enough sleep habitually. Start with an earlier bedtime.
Think About Nutrition
Exercise ultimately gives you more energy throughout the day instead of depleting it. It also has the added benefits of improving mood, sleep quality, and focus. If you do at least 25 minutes of vigorous cardio exercise at least three times a week, you can improve your overall wellness.
Pick a New Habit
Healthy habits will have improved your energy and focus during the day so that you have the capacity to take on your new habit.
The key to habit change, especially when you’re truly exhausted, is to take it slowly and steadily: You won’t be able to change all of your habits in a day.
A.Get Moving |
B.Improve your health |
C.Choose just one to work on at a time |
D.Once you give yourself enough time to rest |
E.Then focus on getting up at a consistent time |
F.You can pick other new habits to fold into your life |
G.But with time, you can develop your new habits efficiently |
【推荐2】Volunteering is a great way to help your community. It is something that people should be doing more often, because it is a great way to give back, while also helping out those less fortunate. Another reason that you should volunteer is because it has a lot of health benefits associated with it, which people don’t seem to really know about.
Decreases Depression
Volunteering is a great way to decrease depression, especially if you are someone who doesn’t have a great support system at home.
A lot of volunteering involves packing boxes or moving things or people, and that is very beneficial for your heart. You might actually volunteer at a local animal shelter, which was great because you can walk the dogs and clean cages, which are all ways to stay active. If you are volunteering doing something you love, you may not even notice that you are exerting physical energy, so it’s much better than just working out because you enjoy it.
Makes You Feel Internally Satisfied
When you volunteer, you feel this satisfaction out of what you are doing, because you know you are helping other people. When you feel this satisfaction, your mental and physical health improves, and you just feel better overall.
Decreases Anxiety
A.A lot of people become depressed because they don’t have friends or family |
B.In order to stay healthy, you have to have a balance of mind and body |
C.If you always feel embarrassed in new social situations, then volunteer |
D.Here are four of the health benefits you can get through volunteering |
E.The reasons are as follows |
F.Builds up Your Mental Strength |
G.Helps You Stay Active |
【推荐3】Although midnight snacks or being too tired to exercise could make people get fatter,there may now be a more scientific reason. A study has shown short or restless sleep changes the way people’s DNA works and makes the body store fat. Fat stores begin to rise when people lose as little as one night’s sleep, the researchers found.
Sleep researchers from Uppsala University in Sweden did a study on people after two lab tests — in one they slept for over eight hours and in the other they did not sleep at all. Researchers then examined the make-up of fat and muscle tissue (肌肉组织), as well as measuring sugar levels in the blood.
The researchers found after just one night of sleeplessness, the body began to store more fat and to lose muscle strength. The body’s decision to store more fat when a person is tired appears to be related to a break in the body clock. When sleep times are changed, it disrupts (扰乱) the way DNA is used by the body and changes which processes are seen as most important, the scientists say. Sleep loss was already known to contribute to overweight but the scientists say they are the first to ever notice the physical changes that lead to putting on weight.
“We saw that the tissue is attempting to increase its ability to store fat following sleep loss,” said study author Jenathan Cedernaes. “We observed signs of breakdown of muscle. We also noted changes in the levels of proteins (蛋白质) related to dealing with blood sugar and this could help explain why the people’s sugar sensitivity (敏感度) was damaged following sleep loss. Taken together,these observations may partially explain why long-term sleep loss can increase the risk of putting on weight as well as the risk of serious diseases.”
The researchers say their findings are important because high levels of body fat increase the risk of the world’s biggest causes of death: cancer and heart disease.

【推荐1】Washington State is best known for its biggest city of Seattle, but it is also home to a staggering number of scenic destinations. Below are the four must-visit places in Washington State as you plan your next trip.
Lake Chelan
Lake Chelan is a hub for scenery, outdoor recreation and wine Lasting in the Pacific Northwest. You can spend a day sipping and sightseeing at places like Vin du Lac Winery, Karma Vineyards or Mellisoni Vineyards. Ride on a seaplane that takes off and lands in the lake itself, or try water-skiing during the summer months. Hiking possibilities are abundant, and on Historic Main Street you can dine on farm-to-table cuisine from a range of independent eateries.
Columbia River Gorge
South of the Rattlesnake Hills, and right in the heart of the Columbia River Plateau, is the Columbia River Gorge. The gorge cuts through the Cascade Mountains forming the boundary between Washington and Oregon, and you can get spectacular views of the gorge from above. The Multnomah Falls cascade right into the gorge at one point, only adding to the beauty of this particular destination.
Spokane
After Seattle, Spokane is the largest city in Washington, and it is located in the eastern portion of the state close to the border with Idaho. In Spokane, you can visit the Riverfront Park and stroll along the banks of the scenic Spokane River. Some of the city's top attractions include the John A.

【推荐2】Children whose minds wander (走神) might have sharper brains, a research suggests.
A study has found that people who let their minds wander easily have more “working memory”, giving them the ability to hold a lot of information in their heads and control it cleverly.
Children at school need this type of memory on a daily basis for a variety of tasks, such as following teachers’ instructions or remembering dictated sentences. During the study, volunteers were asked to perform one simple task during which researchers kept asking if their minds were wandering. In the end, volunteers measured their working memory capacity (容量) by their ability to remember a series of letters mixed with simple maths questions.
Daniel Levinson, a professor at the University of Wisconsin-Madison in the United States, said that those with higher working memory capacity reported “more mind wandering during these simple tasks”, but their performance did not deteriorate.
The results, published online in the journal Psychological Science, appear to make sure that the former research found working memory allows humans to deal with many thoughts at the same time.
Dr Jonathan Smallwood, of the Max Planck Institute for Human Cognitive and Brain Science in Leipzig, Germany, said, “What this study seems to suggest is that, when the tasks aren’t very difficult, people with additional working memory capacity use them effectively to think about other things besides what they’re doing.”
Working memory capacity is also connected with general measures of intelligence, such as reading comprehension and IQ scores. Dr Smallwood added, “Our results suggest the sorts of planning that people do quite often in daily life — when they are on the bus, when they are cycling to work, when they are in the shower — are probably supported by working memory.”

【推荐3】Birds have nostrils on their beaks (喙) that can help them smell all kinds of things. When animals breathe air, they can also breathe in different smells.
The nose can pick up on smells and send information to the brain by the olfactory system. We have an olfactory system, too. This system can help animals understand the world through a sense of smell.
Maybe you’ve used your olfactory system to smell your breakfast, lunch, and dinner or you’re your new school books.
Birds can also use their olfactory systems to sniff out food. The kiwi bird uses its long beak to dig into the dirt. Its nostrils are on the outside and very tip of its beak. It’s thought that they use that sense of smell to pick up chemicals (化学物质) emitted by their food — grubs, worms, and other things that are in the ground.
One bird of prey that has a really great sense of smell are turkey vultures. Vultures are scavengers, meaning they eat dead animals. They have a fantastic sense of smell. They use their nose to pick up chemicals from things that are decaying (腐烂). Turkey vultures have one of the strongest senses of smells among birds. They have been known to smell food that was over a mile away.
But albatrosses, which can have wingspans around ten feet, have been known to sniff out food from even greater distances — about 12 miles away. These seabirds can pick up chemicals from dead fish or groups of fish. They can even sense the smell that krill give off when they are eaten by fish. That helps them find the fish via the krill.
While a sense of smell is helpful for birds, it isn’t the only useful or even sometimes the strongest sense — they also use their senses of hearing, sight, and taste. The next time you watch your chickens, or other birds in the neighborhood, maybe you can observe how they use all these senses.

【推荐1】Johannes Vermeer is such a quiet and introspective (内省的) artist that it took hundreds of years for anyone to notice he was a genius.
A major Vermeer exhibition opens this month at the Louvre in Paris, whose permanent collection includes his great painting of a woman absorbed in close, visually demanding work, The Lacemaker (about 1669-1670). Like other paintings by Vermeer, this image represents modern culture.
So attracted are today’s art lovers by Vermeer that it was thought shocking when a recent survey found that 82% of Americans can’t name who painted The Girl with the Pearl Earring. Well, maybe they don’t go to the movies much.
It is not true to say he was forgotten—that would suggest he was famous in his lifetime. He was not. Vermeer was one more painter among the many who worked for money in the Dutch Republic in the 17th century. He was not a star like Rembrandt. He obviously took himself and his art seriously. His self-referential painting The Art of Painting proves that. Even though he worked all his life in Delft, he painted only 35 known works and left his family poor when he died in 1675 at the age of 43.
It is fitting that Paris is celebrating Vermeer, because it was the French avant-garde (先锋派) in the 19th century who saved him from being completely forgotten. Compare his paintings Woman in Blue Reading a Letter or The Little Street with, say, Edouard Manet’s A Bar at the Folies-Bergere (1882) or Camille Pissarro’s The Boulevard Montmartre at Night (1897) and it is easy to see why the art of Vermeer found its natural audience in Parisian bohemia. (放荡不羁的艺术家)
All these artists are likely to have known about and admired Vermeer due to the efforts of the critic Thore-Burger, a veteran of the 1848 revolution.
Vermeer’s rediscovery is part of the history of modern French art. Vermeer is not only a great artist. He is a great modern artist.

【推荐3】When I watched the film “The Farewell” recently, I found it not only reminded me of my own family’s great lie, but it also reopened old wounds.
Its main characters tell lies that flow from their mouths smoothly. Billi, a Chinese-American artist in New York, and her grandmother in China, tell lies to each other on the phone. Billi, in cold wind, tells her grandma that she’s wearing a hat. She’s not. Her grandma says she’s visiting her sister, while she’s actually ill in hospital. They’re lying to avoid worrying each other, but in fact the grandma has lung cancer. The family know it but won’t tell her for fear that anxiety over the diagnosis (诊断) could kill her before the cancer.
When I was a teenager girl, my parents, both immigrants, got divorced. We never had a discussion about how things would change. We didn’t tell anyone. Instead, we pretended as if nothing had happened. My father did not run away; he slept in a separate room. In the presence of relatives, we acted as a close family. I was puzzled why we insisted on creating the illusion(假象) that everything was O.K..
I asked a professor of multicultural psychology. “Asians tend to have indirect communication,” he said, “In indirect communication, what’s not said is more important than what is said. Eastern philosophy emphasizes balance and harmony, and indirect communication minimizes conflict. So some Asian cultures value the ability to understand indirect messages.”
In the film, the family members show their love for grandma by keeping secret about her condition. Similarly, perhaps my parents intended to save face and preserve harmony. As an Asian-American, maybe all I’ll ever have is a secondhand understanding, and that’s the best I can do.
1. Why does Billi’s grandma tell lies to her according to Paragraph 2?A.Because she’s afraid of the diagnosis. |
B.Because she knows she has lung cancer. |
C.Because she doesn’t want Billi to worry. |
D.Because she has been used to telling lies. |
A.They left their home. | B.They kept secret in public. |
C.They had a discussion. | D.They asked relatives for help. |
