The town of Green Bank, West Virginia, is the site of the largest radio telescope in the world, so Internet connections and anything else that can create electromagnetic(电磁的) waves, such as smart phones and microwave ovens, are banned.

    Green Bank is frozen in time, somewhere in the 1950s, because there's a 33,000-square-kilometer zone of silence due to the telescope. Cell phone towers are forbidden.

    The closer you get to the telescope, the greater the restrictions. There's a 16-kilometer radius(半径) around the observatory where radio-controlled items, even toys, cannot be used.

    Telescope employees even work in a special room that blocks electromagnetic waves from leaving it. “Here imagine a submarine(潜艇), water cannot get inside, and so this room is an electric submarine. No electromagnetic waves can get into this room, just as you can't go beyond it,” Michael Holstein, an observatory officer, said.

    The size of a football field, the telescope is so sensitive that it could pick up signals sent from an alien world. And scientists can't wait for that to happen.

    “All the signals that we now receive with the help of telescopes are signals that come from cosmic objects — stars, galaxies. We have not yet received anything from intelligent civilizations,” scientist Richard Lynch said.

    Local people respect the work of the scientists. “Yes, we are different. Many would say that we live the old-fashioned way, in the past. But for us, it's just the way of life that we have always lived,” Sherry said.

    “When we want to meet friends, we just call each other on a wire phone. And instead of sitting in front of your screen, we talk, we go fishing, to the mountains,” resident Sherry said.

    For the latest news, residents read the weekly local newspaper. When she's looking for a phone number, Sherry reaches for the phone book.

    And instead of Facebook, Sherry enjoys daily conversations with her customers. In this town, everyone knows each other and communication is face to face.

    America is a mobile society. Friendships between Americans can be close and real, yet disappear soon if situations change. Neither side feels hurt by this. Both may exchange Christmas greetings for a year or two, perhaps a few letters for a while - then no more. If the same two people meet again by chance, even years later, they pick up the friendship. This can be quite difficult for us Chinese to understand, because friendships between us flower more slowly but then may become lifelong feelings, extending (延伸) sometimes deeply into both families.

    Americans are ready to receive us foreigners at their homes, share their holidays, and their home life. They will enjoy welcoming us and be pleased if we accept their hospitality (好客) easily.

    Another difficult point for us Chinese to understand Americans is that although they include us warmly in their personal everyday lives, they don't show their politeness to us if it requires a great deal of time. This is usually the opposite of the practice in our country where we may be generous with our time. Sometimes, we, as hosts, will appear at airports even in the middle of the night to meet n friend. We may take days off to net as guides to our foreign friends. The Americans, however, express their welcome usually at homos, but truly can not manage the lime to do n great deal with a visitor outside their daily routine. They will probably expect us to get ourselves from the airport to our own hotel by bus. And they expect that we will phone them from there. Once we arrive at their homes, the welcome will be full, worm and real. We will find ourselves treated hospitably.

    For the Americans, it is often considered more friendly lo invite a friend to their homes than to go to restaurants, except for purely business matters. So accept their hospitality at home!

    From the earliest times, man has been interested in art. People have often worked together to collect and save the world's art treasures.

    Fine art treasures from many countries are kept in an art museum called the Louvre(卢浮宫)in Paris, France. The works of art have been collected by the people of France over many centuries.

    The Louvre has not always been a museum. The first building was a fort(炮台). In 1190, it was the king's castle with high walls and a round tower. It had a moat to keep out his enemies.

    Over the years, the number of buildings around the castle grew. By 1350, the castle was no longer needed as a fort. The Louvre became a palace home for French kings and queens.

    During times of peace, new treasures were brought in. During days of war, many treasures were stolen, and the buildings were damaged.

    When Francis Ⅰ became the king of France in 1515, he brought in artists from many countries. One of the artists was Leonardo da Vinci from Italy. Da Vinci's Mona Lisa is the best known painting in the museum today.

    In 1793, the Louvre became a public museum, just as it is now. It is a place where art treasures have been saved for everyone to enjoy.

Music is all around us. It's an accessible and popular art form which accompanies our daily lives. Advertisers have long understood the popularity and emotional power of music and capitalized on it. They spend much time and money securing the right soundtrack (配乐) for an advertisement in order to boost sales. For example, Microsoft spent a reported US$3 million using Start Me Up as part of their advertising campaign for Windows 95.

As one researcher puts it, "Music expands pictures and colors words, and often adds a form of energy available through no other source." This is supported by other studies, which suggest that music matching the main message of an advertisement has a positive effect on consumer engagement. This is known as "musical congruity" and can result in better attention, a positive emotional response, finally improving the effectiveness of an advertisement.

Take the simple but interesting advertisement for Air France, with the soundtrack of Mozart's Piano Concerto No.23, for example. It projects greatness and elegance in the hope that viewers will associate those qualities with the airline. The research, which looked at hundreds of viewer comments about the music used in advertising, suggested it was successful.

Music is also effective at arousing (唤醒) emotional memories in advertisements creates associations with consumers' past experiences. A good choice of music allows businesses to tap into this nostalgia for commercial benefit.

However, the use of popular music in advertising can also arouse arguments between artistic effort and commercialism. Some people believe a work of art shouldn't be used for the pursuit of profit. The findings of study showed that consumers sometimes passionately oppose the use of music produced by respected musicians in advertisements, as they believe that it destroys the aesthetic integrity (美学完整性). For example, Nike's use of the Beatles' song Revolution was seen by some as using John Lennon's music to sell shoes. It made some Nike wearers so angry that they refused to buy the products.

Juleus Ghunta is a published children's author and award-winning poet. But growing up, he could barely read. Ghunta's family lived in a rural part of Western Jamaica. His mother often had to make tough choices about how to use their limited resources, including a decision to send his oldest sister to school, and to keep Ghunta at home.

When Ghunta finally went to school, he couldn't catch up on his reading skills. Not only had he been kept home from school as a child, but he had not been exposed to books. By the time he entered the sixth grade, he could spell his name, but he still couldn't make out words, spell, or read with understanding.

When Ghunta was about 12, a young teacher decided to start a special reading program for struggling students. Ghunta was the first student to sign up. The teacher was incredibly kind to him. She did not ask anything of Ghunta, except that he worked hard and believed in himself.

Under her guidance, Ghunta's reading skills finally started to improve. He started to feel more confident. "She had left me with the gift of literacy," he said, "and with the value as a human being." His life took a new direction. He graduated from elementary school with a number of academic awards, including one for "most improved in reading". He went on to college. Today, he is the author of two children's books, about overcoming difficult experiences in childhood. He's now working on his first full-length collection of poetry.

"I would love her to see the significant impact that she has made on my life, and the ways in which I have carried this memory of her—the hope and the light—with me and how it continues to be a source of joy."
