To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island—quite a few “No's”．

    There is no pollution, for instance, no dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the whole month of July, and only three hours of black­and­-white TV the rest of the time. There is no hard liquor（酒） on Wednesdays and no beer at any time. There is no handguns; only one prison of thirty­ five rooms in the whole land—an admirable figure, even for a small country of 313,376 people.

    There is no army, air force or navy. There is no tipping（给小费） for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is located just under the Arctic Circle, there is no darkness in summer and no daylight in winter. But thanks to Gulf Stream, the climate is rather mild, with temperatures between 34 degrees and 52 degrees in July.

    The rules on television liquor and guns are the result of government decisions. But the absence of pollution is because of in great part the fact that Iceland gets its power from the thousands of hot springs(泉水) that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power.

    Iceland has been described as a democratic（民主的） independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They wrote their first books in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first, the stories were remembered and passed from generation to generation. They were finally written down between 1140 and 1220. The Icelanders have never stopped writing ever since. “Rather shoeless than bookless，” they proudly say.

    Last night's meteor (流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley's mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead.

     “My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”

    Astronomers—scientists who study stars and planets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.

    There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating (迁徙的) birds. According to the International Dark-Sky Association, “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”

    Countless more animal casualties (伤亡) result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings. But some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person's chances of getting cancer.

    Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

    A handsome middle-aged man walked quietly into the café and sat down. Before he ordered, he couldn't help but noticed a group of younger men at the table next to him. It was obvious they were making fun of something about him and it wasn't until he remembered he was wearing a small pink ribbon(丝带) on the lapel of his suit that he became aware of what the joke was all about.

The man pretended not to notice it, but the whisper and laughter began to get to him. He looked one of the rude young men straight into the eye, placed his hand beneath the ribbon and asked, “This?”

    With that the young men all began to laugh out loud. The man he spoke to said, “Hey, sorry, man, but we were just commenting on how pretty your little pink ribbon looks against your blue jacket!”

    The middle-aged man calmly invited the joker to come over to his table, and politely seated him. As uncomfortable as he was, the young guy had to, not really sure why. In a soft voice, the middle-aged man said, “I wear this ribbon to bring awareness about breast cancer. I wear it in my mother's honor.”

    “Oh, sorry. She died of breast cancer?”

    “No, she didn't. She's alive and well. But her breasts nourished me as a baby, and were a soft resting place for my head when I was scared or lonely as a little boy. I'm very grateful for my mother's breasts, and her health.”

    “Umm,” the young replied, “yeah.”

    “And I wear this ribbon to honor my wife,” the man continued.

    “And she's okay, too?” the young guy asked.

    “Oh, yes. She's fine. Her breasts have been a great source of loving pleasure for both of us, and with them she nurtured and nourished our daughter 23 years ago. I'm grateful for my wife's breasts, and her health.”

    “Uh, huh. And I guess you wear it to honor your daughter, also?”

    “No. It's too late to honor my daughter by wearing it now ……”

    Shaken and ashamed, the young guy said, “Oh, I'm so sorry, mister.”

    “So, in my daughter's memory, too, I proudly wear this little ribbon, which allows me the opportunity to enlighten others. And here…” With this, he reached in his pocket and handed the young man a little pink ribbon. The young guy looked at it, slowly raised his head and asked, “……?”

    I'll never forget the day when Mary came into my office and said, I am too old to learn how to use a computer. I shook my head. Here was a woman who had raised 6 children and who had made great progress in her career telling me that she was too old to learn something new. I told her that I always believed people were never too old to learn.

    Mary followed my advice and did learn how to use the computer. Now, she is retired and leading a very active life volunteering in her community( 社区 ),using her computer skills and helping anyone that needs help.

    When she was in her sixties, one day she called me and said she had played the piano for others all her life, and now she was going to make a CD of her own. My mind flashed back to the day when she told me she was too old to learn. You can imagine my surprise and delight.

    To produce the CD, she had a lot of things to learn. It was not just sitting at the piano and playing. She had to research the songs, learn about copyright(版权),and learn about marketing. It was pretty amazing for someone who once said she was too old to learn. And finally she made it. Now she has her own CD-Mixed Blessings.

    Most of you probably have heard about some people who have gone back to university in their seventies and have also graduated. They are on their way again to charging themselves with a new skill and a new attitude towards life. The point is you are unable to learn anything at any age if you believe you are too old. On the contrary, you can achieve anything at any age if you believe you can.

    Just as John Lubbock said, we may sit in a library and yet be in all quarters of the earth. Here are some of the coolest libraries of the world.

    Stuttgart City Library

    Despite a classic white-on-white color, Stuttgart City Library is one of the most visually appealing modern libraries. The amazing modern and simple look is the product of the Korean architect Yi Eun-young. The German library opened in 2011, and cost nearly 80 million euros to construct.

    Kanazawa Umimirai Library

    Architects from the Coelacanth K&H Architects studio designed the Kanazawa Umimirai Library lo create the best reading environment. Healed floors, an outpouring of natural light, and other features were specifically included lo achieve this goal. The wall, which consists of thousands of tiny openings, allows natural lighting into the building, improving the overall feel of the space. This Japanese library was opened in 2011, and reflects the appearance of many modern and simple spaces.

    Library of Congress

    In 1800, Congress set up the Library of Congress in Washington D.C. Fifteen years later, Thomas Jefferson offered his personal library to replace books that were lost when the British set the building on fire in 1814. His books, which took nearly 50 years to collect, varied from texts on science, literature and philosophy, to books in a variety of foreign languages. These days, the Library of Congress offers more than 155 million items and the largest rare book collection in North America.

    State Library of Victoria

    The Slate Library of Victoria, located in Melbourne, Australia, is one of the largest exhibiting libraries in the world. Though it opened in 1856, major repairs took place between 1990 and 2004. The La Trobe Reading Room is one of the library's main attractions due to its visually amazing architecture. The lawn at the library's front attracts hundreds of city folk each day, who gather for lunch or to enjoy the statues there. The library currently contains over two million books, as well as armor (盔甲) of Ned Kelly, a folk hero against the ruling class.

It's one of the biggest challenges in higher education today: What do you do with the nearly one in five working-age adults who have some college experience, but no degree?

Sokeo Ros was one of them. "I just hated community college," he says. "I made up my mind: I'm never going back to school. I have all these debts, and I don't want to waste my time." Ros,34, was born in Thailand. He dropped out of two colleges, switching majors several times. Meanwhile, he taught dance in Providence, R. I. , struggling to raise his daughter. But in 2012, he found College Unbound that accepts adults, like Ros.

College Unbound is the creation of educator Dennis Littky He is devoted to helping adults make their own path to a degree through College Unbound. Nearly all the students can get scholarship. They are paired one-on-one with advisers who help them make a plan that combines a job with online classes and independent research. Students create online works and show their live exhibitions.

Right now,College Unbound has about 75 students. It makes a great effort to keep the total cost per student under $10,000 per year. So far, the approach seems to be working:85 percent of its students have returned for a second year;60 percent of graduates take less than two years to complete their bachelor's degrees. And nearly nine of 10 College Unbound alumni (校友) are employed full-time.

Littky says College Unbound's goal is to create a new learning experience giving students more than just job training or qualifications. At last it lets adults understand lifelong learning is important for them.

Sokeo Ros experienced that. "At first, I just wanted to get a degree. But I kind of fell in love with the idea that learning is a lifelong experience."
