Over 40 years ago, a country music DJ convention (大会) was held every year in Nashville, Tennessee. Many country performers used to attend (参加) the convention to give their performances. Fans would go to Nashville hoping to see their favorite performers. In the end, so many fans began showing up in Nashville that a festival named Fan Fair was born.

    The first Fan Fair was held in April 1972, in Nashville for four days. Some of country music's biggest stars attended. There were about fifty thousand fans. The first Fan Fair was so successful that planning began almost immediately for 1973. The date was changed to June, when the weather would be better. Over one hundred thousand fans attended the second Fan Fair.

    Every year brought so many performers and fans to Fan Fair that, in 1982, it was moved to the Tennessee State Fairgrounds. Fan Fair stayed at the fairgrounds for another nineteen years.

    There was always the unexpected during the festival. In 1974, former Beatle Paul McCartney attended. In 1992, more than six hundred reporters from Europe, Asia, and South America went to cover the appearance of a popular star, Billy Ray Cyrus, who had introduced a new country line dance. In 1996, Garth Brooks, who made a surprise appearance, signed autographs (签名) for 23 hours.

    In 2001, Fan Fair returned to downtown Nashville as the world's biggest country music festival. Now, over one hundred and twenty-five thousand country music fans go to Nashville every June. As you can imagine, those who want to attend Fan Fair must plan ahead. For example, they need to buy a ticket several months ahead of time. Of course, there's much more to prepare.

You must have written your research paper, your personal essay, your book review—-whatever your school class requires. You think you have provided good information in the needed number of words.{#blank#}1{#/blank#}

    But is it really done? Many teachers and professional writers believe that writing is revision.{#blank#}2{#/blank#}

Revision of writing is a necessary skill for students. The classroom is a good place to practice patience, concentration and listening. There are rewards with spending time with your thoughts and really taking time to compose your ideas in an orderly and reasonable way. You should put away your paper after you have written a first version, or draft. Wait several hours, maybe overnight, before working on it more.{#blank#}3{#/blank#} Not only are you refreshed, but you're looking at things through different eyes. That's what revision literally means—to see again through different eyes.

Following a four-step process may help you with your paper. The first step in the process is invention. It includes forming many questions about your subject. It is called “question-storming”.{#blank#}4{#/blank#}Then comes the revision period. Take your time to read what you've written, to think about it, and maybe to re-shape it based on what you see now, as a kind of new person looking at it with a reader's eyeglasses rather than a writer's. The fourth step is called “publication”.{#blank#}5{#/blank#}In a sense, anytime you turn it over to another person, that's publication.

    Probably, the process takes away some of the tension of writing. And worry about the quality of your writing often disappears when you share that writing.

    If the crust (外壳) of the earth were not pretty solid (坚固的), it would be shaking about and moving up and down frequently. However, there are places in the rocks of the earth's crust where it isn't strongly held together—where faults exist. Along the faults, one rock might push against another with great force. The energy is changed to vibration in the rocks, so they begin to shake and we have an earthquake!

    The most famous one in North America was the San Francisco earthquake of 1906. Seven hundred people died and property (财产) damage amounted to about $425,000,000.The greatest destruction came from the fires that followed the quake.

    One of the most famous earthquakes in Europe took place in Lisbon, Portugal, in 1755. The city was destroyed and at least thirty thousand people were killed. In 1908, in Calabria and Sicily, a quake killed about seventy­five thousand people. In 1915, in central Italy, hundreds of towns and villages were damaged and thirty thousand people were killed.

    Two great earthquakes that caused great damage in Asia took place in Tokyo, Japan, and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama, too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.

    Want to stay away from colds? Put on a happy face.

    Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from cold, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.

    “It seems that positive feelings may reduce the danger of illness,” said the study's chief researcher Sheldon Cohen.

    In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed positive feelings were also less likely to tell their doctors that they felt ill.

    In this study, Cohen's study interviewed 193 adults every day for two weeks. During the interviews, the people told researchers about the happy or sad feelings they had that day.

    After the two weeks, the people were given colds by doctors and had to stay alone in a room for six days.

    The result showed that everyone in the study was equally likely to get ill. But for people who said they felt happy during the research period, their illness was less serious and lasted for a shorter time.

    Cohen believes that when people experienced positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.

    If you're a fan of smart technology, you may have had some sleepless nights lately.

    That's because Alexa, the artificial intelligence (AI) behind US company Amazon's Echo smart speakers, has been "letting out an automatic, creepy (令人毛骨悚然的) cackle," for no apparent reason, according to BBC News.

    Many social media users shared their stories of Alexa scaring them with the seemingly unprompted laugh.

    "Every time Alexa laughs, an angel dies," Tesla and SpaceX founder Elon Musk joked on social media.

    On March 7, Amazon released an update that fixed the problem, saying that the laugh was triggered (引发) by Echo devices mistakenly thinking that users had said the command "Alexa, laugh".

    However, what should have been a funny story raised the ongoing topic of man versus machine.

    With the rise of artificial and robotic technology, "Digital machines have started to demonstrate (展示) broad abilities in pattern recognition, complex communication, and other fields that used to only belong to human," wrote Erik Brynjolfsson and Andrew McAfee in their book The Second Machine Age: Work, Progress, and Prosperity in a Time of Brilliant Technologies. They believe that AI will "do more and more, and our lives will get better".

    However, ever since the earliest days of AI, there have been concerns that some day, software will take over the world, leaving the fate of humans unknown.

    "With artificial intelligence we are summoning (召唤) the demon ," Musk told students during a meeting at MIT in 2014. "If I had to guess at what our biggest existential threat is, it's probably that. So we need to be very careful."

    Many scientists have shared the same concern. The late British physicist Stephen Hawking said at a technology conference in Portugal in November that "computers can, in theory, imitate human intelligence, and exceed it… AI could be the worst event in the history of our civilization." If creators are to safely control AI, however, Hawking suggested that they "employ best practice and effective management".

    "I am an optimist and I believe that we can create AI for the good of the world," he said at the conference. "We simply need to be aware of the dangers, identify them, employ the best possible practice and management, and prepare for its consequences well in advance."

You should try your best to create your own family library so that you and your family are always learning. "It is a great mistake to think that education is finished when young people leave school. Education is never finished even if you grow older," said Mrs Child in The Mother's Book. "Collecting a library of books in your home is really helpful to your family.”

"What is really interesting about having so many books in your home is that a book you purchase has a chapter about the deeper knowledge of your favorite subject at school," said a university graduate. Researchers in a study tries to identify what parents do has an influence on how well their children do on standardized tests. One positive aspect they find is the availability of a large number of books at home. This has a stronger connection, especially when you read to your children every day. The more books your older kids have access to at home, the more likely they are just to be reading for fun, rather than having to wait for weekly trips to the library.

John Henry, one educated parent, said, "I have been homeschooling my children using the philosophy of A Thomas Jeffer son Education. This philosophy of learning is based on the reading of classic books." Clinton Fadiman said, "When you reread a classic, you do not see more in the book than you did before; you see more in you than before." Classic books also make you smarter and wiser! The wisdom comes in the examples in the lives of the characters.

"It is within your power to guide your youth in their reading and to cultivate in their hearts a desire for good books. It is the most unfortunate if a person is not possessed with the desire for good reading. The reading habit, like charity, should begin at home," said Mrs Child.
