Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture？

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleeps fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey (冰球) final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning. Thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

    It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

    If you're showering every day, you're probably over doing it. In fact, showering too often can actually hurt your body in the long run.

    As Time's public health column explains, daily showers are common due to social norms more than any proper health need. We connect being freshly showered with being attractive and pleasing, so we tend to showering often to feel better.

    But what's the ideal shower frequency? In terms of your health — not how you look or smell — probably once or twice a week, assistant professor of dermatology at George Washington University, Dr. C. Brandon Mitchell says. “Your body is naturally a well-oiled machine,” he says. “A daily shower isn't necessary.”

    Of course, your situation may vary. If you have a job like car maintenance or construction, you'll obviously have a visible layer of dirt you'll need to wash off every single day. Similarly, if you work out every day, you may not have any health risks by washing every day, but you'll still be smelly. If you feel like you need to take daily showers for aesthetic（审美的）reasons, at least make most of them light showers. “I tell patients who shower daily not to soap their whole bodies,” Mitchell says. Hit your pits, butt and groin, which are the areas that produce strong smells. The rest of your body doesn't need much soaping, he says.

    Too much time spent under the hot water can dry out your skin, cause cracks（裂纹）that can lead to infections or germs getting into your skin, and take away the natural oils on your skin that help keep it healthy. So, even if you're aiming to be your most presentable, be sure to keep it moderate to avoid hurting your skin in the long run.

    Exciting screams of joy from two happy little girls rang across the beach. But I walked along, ignoring them. I'd come to this faraway beach on my sailboat, a place to escape. My marriage was in trouble. I worried about the harm to my two boys. But I didn't know how to make things better.

    “Help! Help!” The girls screamed. I saw one girl was at the edge of the surf, yelling. I charged into the waves, swam to her and seized her. “But where is the other girl?” I looked across the water and saw a small head after a big wave. I shifted the girl Td rescued to my back. She told me the other girl was her sister. For a moment I thought of my boys. How much they loved each other. How much I loved them.

    I quickened my swimming and held the second little girl. We were at least 50 yards from land. I couldn't swim that far with two girls hanging on to me. But there was no time to wait. I swam as hard as I could, but the weight of the girls grew heavier with every minute. My lungs burned. I opened my mouth to take a breath, but instead swallowed water. I couldn't breathe. From behind me I felt an unbelievable force, lifting.

    “Mommy!” The cry drew my attention. I looked up. An elderly man was trying to drag me out of the water. Two women were swimming toward shore. “Thank you,” one of the woman cried. “You saved my daughters.” My efforts and my struggles had paid off. I thought of that big wave, lifting me and pushing me. When my body had failed me, and when all hope was disappearing, I was given the strength I needed.

    I stoop up. My family were waiting for me. There were things I could do. I just needed to make an effort. The strength would be given to me.

    What is language for? Some people seem to think it's for practicing grammar rules and learning lists of words—the longer the lists, the better. That's wrong. Language is for the exchange of ideas and information. It's meaningless knowing all about a language if you can't use it freely. Many students I have met know hundreds of grammar rules, but they can't speak correctly or fluently（流利地）. They are afraid of making mistakes. One shouldn't be afraid of making mistakes when speaking a foreign language. Native speakers make mistakes and break rules, too. Bernard Shaw once wrote,  “Foreigners often speak English too correctly. ” But the mistakes that native speakers make are different from those that Chinese students make. They're English mistakes in the English language. And if enough native speakers break a rule, it is no longer a rule. What used to be wrong becomes right. People not only make history, they make language. But a people can only make its own language. It can't make another people's language. So Chinese students of English should pay attention to grammar, but they shouldn't overdo it. They should put communication first.

    Most people want to know how things are made. They honestly admit, however, that they hardly know a thing when it comes to understanding how a piece of music is made. Where a composer (作曲家） begins, how he manages to keep going- in fact, how and when he learns his trade - all are covered in complete darkness. The composer, in short, is a man of mystery (神秘）.

    One of the first things the common man wants to know about is the part inspiration (灵感） plays in a composer's work. He finds it difficult to believe that composers are not much interested in that question. Writing music is as natural for the composer as eating or sleeping for all. Music is something that the composer happens to have been born for.

    The composer, therefore, does not say to himself: "Do I feel inspired?" He says to himself. "Do I feel like working today?" And if he feels like working, he does. It is more or less like saying to himself: "Do I feel sleepy?" if you feel sleepy, you go to sleep. If you don't feel sleepy you stay up. If the composer doesn't feel like working, he doesn't work. It's as simple as that.

At a large forest park in eastern Beijing, 11 birds on the state-level protection list were recently released.

These birds had recovered after the Beijing Wildlife Rescue and Rehabilitation Center rescued and took care of them. "We will speed up our efforts to push the establishment of district-level wildlife rescue centers to jointly guard the health of wildlife," said Du Lianhai, director of the center.

The center was set up in 2001 and built a wildlife rescue base in the capital's Shunyi District in 2005. Staff at the base have rescued and rehabilitated over 30,000 wild animals in total.

Wildlife protection has been strengthened in Beijing in recent years. On June 1, the city's newly adopted regulation on wildlife protection took effect, introducing stricter and more concrete measures to protect the environment and wildlife.

For example, the regulation states clearly that Beijing bans hunting throughout the year, compared with the previous regulation which bans hunting during the periods of March to May and September to November each year. The new regulation also gives severer punishment for poachers.

After years of monitoring, data with the Beijing Gardening and Greening Bureau recently showed ecological reconstruction progress. The species and quantity of wild animals in Beijing are continuously increasing, with the number of terrestrial spinal wild animals (陆地脊椎野生动物) growing from 461 species in 1994 to more than 500. The habitat of the endangered bird has expanded from Fangshan District to the whole city, according to the bureau.

"The enforcement of the new regulation marked a new phase in Beijing's wildlife protection work," said Dai Mingchao, deputy director of the Beijing Gardening and Greening Bureau.

"We will step up the publicity of the regulation and raise citizens' awareness of wildlife protection," Dai said. "In our integrated protection of mountains, rivers, forests, farmlands, lakes and grasslands, we take into full consideration the requirements of food-chain construction, ecological corridor construction, and wildlife and their habitat protection."
