    We humans spend about one-third of our lives asleep. This may sound like a lot of time, but it is not wasted. Sleep not only helps us stay healthy but it also helps our brains remember. Our brains need good sleep to remember what we do and learn during the other two thirds of our lives when we are awake.

    Researchers at the University of Wisconsin-Madison have found that sleep helps improve brain performance by shrinking(收缩)synapses in the brain. A synapse is the area where cells pass messages to other cells.

    Scientist Chiara Cirelli is a leader at the school's Center for Sleep and Consciousness. She told the reporter that sleep is when the human brain mixes information it has learned while awake into its general collection of knowledge. Meanwhile, the brain forgets unimportant details. This forgetting is important. It makes space for new learning and new memories.

    Cirelli said that the Centers research began with this hypothesis(假设): We sleep so that our brain can repair and refresh itself. She said the idea seems simple and reasonable. However, testing and discovering how it works has been extremely difficult.

    Synapses are only about 20-40 nanometers(纳米)wide. The team began their study by measuring the size of the synapses to look for changes in these already tiny spaces between nerve cells. Cirelli says the process(过程) is difficult because"all the actual measurements of the synapses have to be done by hand." The team had to wait until improvements in laboratory technology made it possible to see these tiny changes. A University of Wisconsin press release called the research a"huge job." Many research specialists worked for four years to photograph, rebuild and study certain areas of a mouse brain. The report also said the scientists measured 6,920 synapses.

    Cirelli says they found that our synapses shrink as our brains clean themselves during sleep. We wake up refreshed and ready to fill those synapses with new information. The research findings are the result of years of hard work at the University of Wisconsin Madison. The researchers published their findings in the journal Science.

(1)、How does the brain help improve our memory while we are sleep?
A、By not forgetting any learnt knowledge. B、By keeping learning new information. C、By adding new knowledge to its old collection. D、By repeating information learnt before.
(2)、What is the fifth paragraph mainly about?
A、The size for the synapses. B、The difficulties in the measuring work. C、The preparations for the measuring work. D、The result of the measuring work.
(3)、What can we infer about the research work?
A、The synapses were found bigger after a good night's sleep. B、The findings proved their hypothesis was right. C、The team began their research as soon as they decided to. D、The researchers carried out their work with a human brain.
(4)、What is the result of the research?
A、Sleep helps us keep healthy. B、Sleep takes one-third of our lifetime. C、Sleep helps the brain shrink. D、Sleep helps us learn better.

    Well, parents, surprise! Lots of us are using Twitter and Facebook to thumb rides, and not just to school. It's awkward to be refused when you call a friend and ask for a ride. But with Twitter, you just look for other people heading the same way.

    It may sound risky, so many teens stay within their own social circles to find rides, and don't branch out beyond friends when asking on Twitter just like me, but to some young people, especially those taking longer trips, stranger danger is less of a concern.

    “I think the digital connection of young people is really important, because younger generations grew up sharing things on line, sharing files, photos, music, etc, so they've been very used to sharing,” said Juliet Schor, a sociology professor at Boston College.

    The sharing economy got big during the recession (经济衰退), allowing people to access more goods, services using technology and even to share costs. And that technology, for me, is what the car was for my mom, a gateway to more freedom, like what my friend Earl says, “The symbol of freedom isn't the car any more because there's technology out there connecting you to a car.”

    According to the researchers at the University of Michigan, 30 years ago, eight in ten American 18-year-olds had a driver's license compared to six in ten today. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license but an iPhone.

“Driving, for young people, does mean they have to disconnect from their technology, and that's a negative. So if they could sit in the passage side and still be connected, that's going to be a plus.” Schor continued.

    To me, another plus is that ridesharing represents something, something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, some of us still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on Twitter.

    When school started on that warm August day, I threw myself into everything I did, including playing volleyball. I decided to become beautiful, or at the very least, skinny. I stopped eating completely. Soon I began losing weight, which thrilled me, and I even grew to love the tiredness and lightheadedness( 头晕)that came with my poor diet, for those feelings meant that I was winning.

    As the season progressed, things had become tense between my head volleyball coach, Coach Smith, and me. She felt that something was wrong with my health. She talked with me about my eating and was angry that I wouldn't listen to her when she tried to make me eat. She tried to persuade me in a determined way and so we fought constantly. Then my hunger started to affect my performance. I was so tired that practice and games were becoming a struggle. One afternoon, with hurt in her eyes, Coach Smith asked me what I had eaten and I told her nothing yet. She looked at me, disappointment in her eyes, knowing she couldn't make me stop, and walked away.

    A couple of weeks later I attended a formal dinner for our volleyball team. I stood there as my coach managed to say something nice about me. I realized then that I had ruined my senior year by being disrespectful, and I had probably ruined hers as well. So that evening I wrote her a letter apologizing and thanking her.

    Then one Saturday, as I was reading in the library, I felt someone gently take my arm and say softly, “Lynn Jones, how are you doing?” I looked up and saw the familiar face. “Thanks for the letter,” she said. “It meant a lot.” When I think of a coach, I think of someone above me, someone who gives instruction — not a friend. But Coach Smith is different, and, like any other good friend, she dealt with my problem in a determined way even when I hated her for it at that time. I didn't deserve her kindness, but she gave it anyway. I will forever be grateful for her help, and now for her friendship.

    As health care costs continue to rise, a growing number of companies are working out programs designed to keep their employees healthy.

    Thomas Chapple is the senior vice president. “It's really important to us because medical costs are going up like crazy, he says. This company spends more than 200 million a year on medical costs for its employees around the country. The best thing we have seen as a way to control the medical cost is individual fitness.”

    We have a fitness center, “Shawn Flaherty, director of public relations for Freddie Mac.,” says, “We have a health benefits plan that encourages people to work out three times a week, get cholesterol (胆固醇) checks, as well as 'not to smoke.' If they do that, it will cost them less for the health benefits.”

    Rachelle Clark works for Freddie Mac. “I feel great. You know the benefit is rewarding. I like to look good and feel healthy. I am just fortunate that I work for the company that provides some type of facility for the employees.”

    While on-site fitness centers are popular, some companies pay membership fees at local gyms for employees. The companies also offer classes such as boxing, yoga and dancing. Employees see those health programs as a valuable benefit.

    Tom Brook exercises five days a week. As a newspaper reporter he has a tight schedule, although Tom says it's not that difficult for him to make time for a workout. “It is great. It is right here where we work,” says Tom, “So everybody gets a chance to use it whenever they want to. I have lost weight and never been in better shape.”

    The programs may not be a magic cure for rising health costs, but they seem to have a positive impact on both employers and employees.

    For Chinese, it's a time for dragon boat racing and Zongzi (粽子). But across the Yellow Sea, South Korea, wrestling (摔跤) and swing play are the highlights. However, both events go by the same name—the Dragon Boat Festival—which falls on May5 of the lunar calendar.

    One festival, two cultures: does one nation have the right to call its own? It has been reported that South Korea will apply (申请) to the United Nations Educational, Social and Cultural Organization (UNESCO联合国教科文组织) to make the celebration its cultural heritage (文化遗产). If successful, people from other countries may see the Dragon Festival as a Korean creation.

    As the birthplace of the yearly event more than 2, 000 years ago, China is not happy with the situation. "It would be a shame if another country successfully made a traditional Chinese festival part of its own cultural heritage ahead of China," said Zhou Heping, deputy culture minister. The Ministry of Culture is even thinking of making its own application to UNESCO, covering all traditional Chinese festivals, including the Dragon Boat event.

    Over the years, the Dragon Boat Festival has spread throughout the world. In Japan and Viet Nam, as well as South Korea, the festival has mixed with and become part of local culture. With this in mind, some experts say that it is meaningless to argue about which country the festival belongs to. "No one can deny that it came from China," said Long Haiqing, an expert from Hunan Province. "But if all the countries involved can protect culture heritage together, they will all benefit."

    In ancient Egypt, the pharaoh (法老) treated the poor message runner like a prince when he arrived at the palace, if he brought good news. However, if the exhausted runner had the misfortune to bring the pharaoh unhappy news, his head was cut off.

    Shades of that spirit spread over today's conversations. Once a friend and I packed up some peanut butter and sandwiches for an outing. As we walked light-heartedly out of the door, picnic basket in hand, a smiling neighbor looked up at the sky and said, "Oh, boy, bad day for a picnic. The weatherman says it's going to rain." I wanted to strike him on the face with the peanut butter and sandwiches. Not for his stupid weather report, for his smile.

    Several months ago I was racing to catch a bus. As I breathlessly put my handful of cash across the Greyhound counter, the sales agent said with a broad smile, "Oh, that bus left five minutes ago." Dreams of head-cutting!

    It's not the news that makes someone angry. It's the unsympathetic attitude with which it's delivered. Everyone must give bad news from time to time, and big winners do it with the proper attitude. A doctor advising a patient that she needs an operation does it in a caring way. A boss informing an employee he didn't get the job takes on a sympathetic tone. Big winners know, when delivering any bad news, they should share the feeling of the receiver.

    Unfortunately, many people are not aware of this. When you're tired from a long flight, has a hotel clerk cheerfully said that your room isn't ready yet? When you had your heart set on the toast beef, has your waiter merrily told you that he just served the last piece? It makes you as traveler or diner want to land your fist (拳头) right on their unsympathetic faces.

    Had my neighbor told me of the upcoming rainstorm with sympathy, I would have appreciated his warning. Had the Greyhound salesclerk sympathetically informed me that my bus had already left, I probably would have said, "Oh, that's all right. I'll catch the next one." Big winners, when they bear bad news, deliver bombs with the emotion the bombarded (被轰炸的) person is sure to have.
