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.

    Hundreds of years ago, news was carried from place to place by people on foot or by horse. It took days, weeks and sometimes months for people to receive news. Now it is possible to send words and pictures around the world in seconds. Billions of people learn about news stories of their own country and all over the world every day, either by watching TV or reading newspapers.

    Newspapers have been an important part of everyday life since the 18th century. Many countries have hundreds of different newspapers. How do newspaper editors decide which news stories to print? Why do they print some stories and not others? What makes a good newspaper story?

    Firstly, it is important to report new stories. TV stations can report news much faster than newspapers. Yet, newspapers give more about the same story. They may also look at the story in another way, or they may print completely different stories to those on TV.

    Secondly, a news story has to be interesting and unusual. People don't want to read stories about everyday life as a result, many stories are about some kind of danger and seem to be "bad" news. For example, newspapers never print stories about planes landing safely, instead they print stories about plane accidents.

    Another factor (因素) is also very important in many news stories. Many people are interested in news in foreign countries, but more prefer to read stories about people, places and events in their own country. So the stories on the front page in Chinese newspapers are usually very different from the ones in British, French and American newspapers.

    When people today talk about a tiny house, they probably mean the trendy living space that's about the size of a shed (棚). But you would have to be five inches tall to live in the original tiny houses. Dollhouse(小房子)，which have been around for several centuries, don't offer shelter to real people, but they provide a vivid（生动的） experience of life in times and places both real and imaginary.

    The National Building Museum in Washington, D.C., lets visitors time travel in this tiny world through ―Small Stories: At Home in a Dollhouse,” an exhibit that opened Saturday. Visitors can see twelve dollhouses from the Victoria and Albert Museum in London, England, which contain amazing tiny furnishings. But those people who put together the exhibit also wanted visitors to know the characters inside.

    “It's 300 years of British homes told through their inhabitants (居民),” said Alice Sage, who is in charge of the London museum.

    So as visitors look inside the Tate Baby House, a fancy townhouse from 1760, they can push a button to hear a young woman get a lecture from her mother on the proper way to run a home. In the Killer Cabinet house, a servant named Betsy complains about the problems of city life in the 1830s. “We've got the cat to keep the rats away,” she says.

    That dollhouse was John Killer's gift to his wife and five daughters. The girls were allowed to play with the house, but they probably also learned a few lessons, Sage said.

    “The kitchen of the house would have been the perfect way to teach the girls about the management of a home,” she said, noting the tiny dishes and pots.

    Those who prefer a more modern look won't be disappointed. There are two rooms displaying a white dollhouse from 1935, an apartment house from the 1960s and a brightly colored 21st-century design.

    The end of the exhibit shows how imaginative design sometimes works best in small spaces.

    The Building Museum asked twenty-four artists, designers and architects from across the United States to each create a “dream room” from the past, present or future. Some of these unique small rooms were made using traditional furnishings, others from materials such as clay, insects, 3D-printing, and even peeps marshmallow candies!

    We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It's called wireless charging and this trend is just starting.

    Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they're placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won't need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.

    Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.

    Think plants are just boring green things that you use for food and decoration? Think again! Plants are able to do some pretty awesome things that you're probably totally unaware of.

    Researchers have discovered that plants have the ability to communicate with an underground network made up of fungus (真菌) , which serves the plants in many ways. Tomato plants use the fungus web to warn each other of their own unhealthy conditions. Trees connected through the fungus network could move nutrients (养分) to and from each other. It is believed that larger trees move nutrients to smaller ones to help them to survive.

    Not only that, but they can also damage unwelcome plants by spreading poisonous chemicals through the fungus. It sounds like the plant world had the Internet before we did.

    Some plants have a rather impressive line of defense against being eaten. When sensing they are being swallowed, they give off a chemical into the air that attracts the insect's natural enemy. The enemy attacks the bug, thus saving the plants. This is basically the plant kingdom version of getting your older brother to beat up that kid who steals your lunch money.

    You might be aware that humans and animals have an internal clock. But did you know that plants also have this clock? This means they can prepare for certain times of day just like we do. Is it because they can react to light at sunrise? In a study, scientists found that plants use the sugars they produce to keep time, which help to regulate the genes responsible for the plant's own internal clock. So, in a sense, wake up with petunias (矮牵牛) is just as valid as ―wake up with the chickens.

    Nature is full of surprises. So for those of you who didn't know the wonders of plants, now you do.

    Parents do not owe (欠) their children a college education. If they can afford it, they can certainly send them to a good university. But they needn't feel guilty if they can't. When children grow up and want to get married, their parents do not owe them an apartment. They do not have the duty to look after their grandchildren, either. If they want to do it, it must be considered a favor, not an obligation.

    Do parents owe their children anything? Yes, they owe them a great deal.

One of their obligations is to give their children a personal worth. Children who are always made to feel stupid and unworthy, constantly compared with brighter brothers, sisters, or cousins will become so unsure, so afraid of failing that they won't try at all. Of course they should be properly corrected when they do wrong, but it's often better to let children learn their mistakes by themselves in time. All their parents should do is to trust them, respect them, understand them and give them chances to try and fail. They must learn to stand failure. When criticisms (批评) are really needed, they should be balanced with a smile and a kiss. That is the way children learn.

    Parents owe their children a set of solid values around which to build their lives. This means teaching them to respect the rights and opinions of others; it means being respectful to elders, to teachers, and to the law. The best way to teach such values is by deed. A child who is lied to will lie. A child who sees no laughter and no love in the home will have difficulty laughing and loving.

No child asks to be born. If you bring a life into the world, you owe the child something.
