Once a boy came to ask a fisherman how to become cleverer, because his mother always called him “foolish boy”.

    “That's easy,” answered the fisherman. “I know one way to make you become cleverer.”

    “Really?”

    “Of course. It is said a fish head is good for brain. If you eat one, you'll become cleverer indeed. Pay only three pounds for one fish head.” The boy paid him three pounds and the fisherman cut off a fish head and handed it to him.

    A raw fish head is not good—not even for a hungry boy to eat but the boy ate it up in  two gulps.

    “Do you feel anything?” asked the fisherman.

    “Not in my head,” said the boy.

    The boy lay on the ground and thought. “One whole fish costs only two pounds. I have paid him three pounds for the fish head. Why couldn't I have the whole fish for soup, a head for brain and one pound left over?” He jumped up and shouted at the fisherman. “You thief! You are fooling me!” The fisherman laughed, saying, “The fish head works now, you see.”

    A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.

    Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.

    “This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.

    As for the Locata's correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.

    The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata's signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK' s General Lighthouse Authorities.

    Locata's technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

    Every people uses its own special word to show its ideas and feelings. Some of these expressions（表达，说法） are commonly used for many years. Others are popular for just a short time. One such American expression is “Where's the beef?” It is used when something is not as good as it is said to be. In the early 1980s “Where's the beef?” was one of the most popular expressions in the United States. It seemed as if everyone using it at the time.

    Beef, of course, is the meat from a cow, and food is more popular in America than a hamburger made from beef. In the 1960s a businessman named Ray began building small restaurants that sold hamburgers at a low price. Ray called this “McDonald's”. Ray became one of the richest businessmen at last in America.

    Other business people watched his success. Some of them opened their own hamburger restaurants. One company called “Wendy's” said its hamburgers were bigger than those sold by McDonald's or anyone else. The Wendy's Company began to use the expression “Where's the beef?” to make people know that Wendy's hamburgers were the biggest. The Wendy's television advertisement showed three old women eating hamburgers. The bread that covered the meat was very big, but inside there was only a bit of meat. One of the women said she would not eat a hamburger with such a little piece of beef. “Where's the beef?” she shouted in a funny way. The advertisement for Wendy's hamburger restaurants was success. As we said, it seemed everyone began using the expression “Where's the beef?”.

    Some people find visiting ordinary museums to be a bit dull. Fortunately for them, there are unusual museums to check out, such as underwater museums!

    How can you visit and what can you see?

    Many underwater museums are supported by companies that offer guided tours. A trained guide leads groups around a stunning underwater display of statues in each museum. Depending on the depth of the museum, visitors may be able to view the sculptures from a glass bottomed boat or by swimming on the surface. Other underwater museums are deeper and are most accessible to scuba divers.

    Why are the museums underwater?

    Underwater museums have many functions. One of their aims is to create a man-made reef environment where sea creatures can live. That's why some of the museums are located in areas that were damaged by hurricanes or are considered underwater ''deserts''. The statues in the museum are designed in a way that encourages the growth of coal and plant life. Over time, the statues and plants attract a growing number of fish to the area.

    Florida, U.S.A.

    Florida is home to different types of underwater museums. The state's newest underwater museum, the Underwater Museum of Art, can be found off the coast of Grayton Beach. This part of the Gulf Mexico is an underwater desert, so creators hope that the exhibit will improve the marine ecosystem.

    Cancun, Mexico

    For years, Cancun has been a popular tourist destination. And one of the major draws is the water. The Museo Subacuatico de Arte is an ideal place for snorkelers and first-time divers. There they can enjoy more than 500 statues that help to make up a man-made reef. This museum was created to offer visitors a replacement for the areas natural reef, which has been damaged.

    Canary Island, Spain

    Museo Atlantico, off the coast of Lanzarote, has an impressive display of more than 300 statues. They were created by the same sculptor who made the Cancun statues. They focus on man's interaction with the marine world.

    If you find yourself checking your phone first thing in the morning, if you find you're text-messaging while driving, checking your phone instead of working on an important assignment—you are addicted.

    Don't worry. The new NoPhone might be just the thing you need. It looks and feels exactly like a smartphone, but it does nothing. It's just a piece of plastic that you can carry around in your hand to fool yourself.

    NoPhone is currently a prototype(手机模型) that will cost only $12 once it hits the market. Its makers are trying to raise $30,000 in order to cover the production and marketing costs.

    Dutch designer Ingmar Larsen, who helped create the NoPhone, said that he had the idea as a joke along with his friends Van Gould and Ben Langveld. To their great surprise, the idea received a lot of attention online and people from all over the world started placing requests for NoPhone of their own, so that's when the three friends decided to raise money for mass production.

    David H said," I used to sleep with my phone in my hand, but my night terrors would cause me to throw it across the room in an unconscious panic. With the NoPhone, I can still enjoy the comfort of holding a phone in my sleep, without waking up to a broken screen, thanks, NoPhone."

    If you're interested in NoPhone, but concerned about not being able to take selfies anymore, don't worry. The makers do have an update at no extra charge—the mirror sticker. That way, they say, you can enjoy "real-time" selfies with your friends when they're standing right behind you.

World War Ⅱ lasted from 1939 to 1945.Life changed for everybody,including women and children because of the war.Millions of people lost their lives during the war.The Diary of a Young Girl was a record of that time.The book was written by a girl named Anne Frank.

After the war,her father collected her diaries and the book The Diary of a Young Girl came out in 1947.It has been put into over 30 languages since then.The book has been read by people all over the world.In her diary,Anne wrote down her thoughts,her feelings,her hopes and her dreams for the future,"I want this diary itself to be my friend,and I shall call my friend Kitty." "I can't spend all day complaining because it's impossible to have any fun!...Every day,I feel the beauty of nature and the goodness of the people around me.With all that,why should I be sad?"

The Diary of a Young Girl has also become a symbol of the greatness of the human spirit.It is called one of the wisest and most moving records on war.
