Minecraft, a video game with which you can build virtual（虚拟的） worlds, will be used in the classroom. Microsoft bought the game from its Swedish creator for 2.5 billion dollars. Now, the software（软件） company wants to offer schools a special educational version（版本）.

    MinecraftEdu is an add-on to the game, which has specially created by teachers for classroom use. While thousands of classes around the world are already using Minecraft in their lessons, Microsoft wants to make it easier for schools to use the software.

    Minecraft is a game that can be used in many subjects, including maths, science and geography. Microsoft wants to add new features to the educational version, for example letting students take photos and putting them into an online diary. The new version will allow children to download the game and at home without having to pay more money for it. Microsoft is expected to ask students and teachers for about 5 dollars a year to use the game in school and at home.

    According to Microsoft, Minecraft has 100 million players around the world. It has become one of the best-selling games of all times. Pupils can create their own virtual worlds with the help of special building blocks. Joy Morsi, a New York high school teacher, says that Minecraft helps develop the imagination of children in the classroom. Besides, teachers around the world create new things and share them with others, so that the Minecraft community keeps growing.

    Microsoft plans to make the game of available to pupils and students of all ages, from primary school through to college. the company plans to add Minecraft to an Office 365 account(账户), so that it can also sell more of its Office software.

    Years ago, the American writer Kurt Vonnegut often said there was one story that would always make a million dollars: "Cinderella"(《灰姑娘》).

    "Cinderella" made more like $70 million in ticket sales when it opened last weekend. But the movie got a mixed reaction. David Rooney of The Hollywood Reporter praised the movie and said, "Anyone will find something to enjoy in it." Steven Rea of The Philadelphia Inquirer called the movie "a winning re-do." Richard Corliss of Time magazine wrote that "Disney finally got Cinderella right." Other people were not as happy with the movie. Sara Stewart of the New York Post wrote, "This Cinderella is all dressed up with nowhere very interesting to go."

    Although different people think differently towards the movie, what is clear, however, is the movie's business success. It is not only popular in the theaters but also in sale. And Disney has widened its usual market for "Cinderella" products.

    There are products connected to the Disney movie targeted(面向) not only at little girls, but women, too. For example, the famous shoe designer Jimmy Choo worked with Disney to create "Cinderella's shoes." You can buy them for about $5,000. At that price, you would not want to lose one at the party, even if that is the way you get your prince(王子).

    The makeup(化装品) company MAC quickly sold all its products connected to "Cinderella." HSN is a popular website selling clothing and objects for the home. The marketer is now also selling "Cinderella" products.

    So, is there anything left for the children, those people we think of as the traditional audience for the age-old tale? Yes, you can find toys and other children's products at the American store JC Penney. Of course, you can also visit a Disney store.

    Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes, the pieces of paper that you can stick almost anywhere and then remove without leaving any sign that they are there, are an example of such an invention.

    Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from an upsetting experience he often had while singing in his church choir. Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.

    Around that time, Fry heard about a new adhesive(粘合剂) that a colleague, Dr. Spence Silver had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough not to tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.

    A short time later, Fry realized that his new invention had even more uses than being a great bookmark. He came to this realization when he wrote a note on one of his new “bookmarks” and attached it to a report he was going to give to a colleague. Soon, co-workers were asking Fry for more sample of his invention so that they could use the new type of notes themselves.

    Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the sticky pieces of paper for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.

    It's undeniable that spending time outdoors and in nature lifts our spirits and makes us feel more centered and at peace. When we breathe in fresh air, and enjoy the beauty of trees, streams and oceans, we naturally tend to feel more connected to ourselves and others.

Over the past decade, scientists have been exploring why nature — and dirt specifically — is such a powerful tool in improving our mood. According to researchers, the secret may lie in the microbes (微生物)of the soil. One bacterium specifically—-Mycobacterium Vaccae (M. Vaccae) —has been identified as having the power to affect our moods and cognitive function as well.

    Experiments conducted at Sage Colleges in New York found that contact with M. Vaccae can increase serotonin levels in the brain — a chemical that is associated with higher levels of happiness, increased focus, and reduced anxiety. In order to explore how the bacteria can improve learning, researchers Dory Mathews and Susan Jenks experimented with mice in a maze. Mice that ingested the bacteria navigated the maze twice as fast as the control group and proved less anxious as well.

    Humans can absorb M. Vaccae just by playing in the dirt. We take in it when we breathe, we consume it in organic vegetables, and it can also enter our bloodstream through skin contact, especially where we have open cuts. This may explain why children in school perform better after break.

    Neuroscientist Christopher Lowry at the University of Bristol in England believes that he has identified why this incredible bacterium works. "What we think happens is that the bacteria activate immune cells, which release chemicals called cytokines that then act on receptors on the sensory nerves to increase their activity.”

    Beyond the power of M. Vaceae, scientists have been proving for decades that exposure to dirt, and the huge number of microbes found in dirt, can strengthen our immune system. When our body comes into contact with bacteria, it stores die information in a type of library and can then use that information to fight sickness and infection more effectively.

    Happiness, focus, less anxiety… I'll take a double dose of dirt; please!

    For some people, music is no fun at all. About four percent of the population is what scientists call "amusic." People who are amusic are born without the ability to appreciate music or recognize musical notes (音调). Amusic people often cannot tell the difference between two-songs. Amusics can only hear the difference between two notes if they are far apart on the musical scale.

    As a result, songs sound like noise to an amusic. Many amusics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. Their ability to enjoy music sets them apart from others. It can be difficult for other people to identify with their condition. In fact, most people cannot begin to understand what it feels like to be amusic. Just going to a restaurant or a shopping mall can be uncomfortable or even painful. That is why many amusics intentionally stay away from places where there is music. However, this can result in withdrawal and social isolation. "I used to hate parties," says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition.

    Scientists say that the brains of amusics are different from the brains of people who can appreciate music. The difference is complicated, and it doesn't involve defective hearing. Amusics can understand other nonmusical sounds well. They also have no problems understanding ordinary speech. Scientists compare amusics to people who just can't sec certain colors.

    Many amusics are happy when their condition is finally diagnosed (诊断). For years, Margaret felt embarrassed about her problem with music. Now she knows that she is not alone. There is a name for her condition. That makes it easier for her to explain. "When people invite me to a concert, I just say, 'No thanks. I'm amusic,'" says Margaret. "I just wish I had learned to say that when I was seventeen and not seventy."

    How did the sea horse get its name? It's not hard to guess. The top half of this fish looks like a small horse. But looking at the sea horse's tail, you might think "sea monkey" is a better name. Then there's the sea horse's pouch(袋). "Sea kangaroo" might also be a good name for this fish.

    Sea horses live in warm ocean waters all over the world. They keep safe from other fish by hiding in plants and grasses that grow under the sea. They can also change colors to match their surroundings(环境). A sea horse remains in one place for hours at a time by winding(缠绕)its tail around a plant. It feeds on live food, such as small shrimp. For a fish that doesn't move around much, the sea horse eats a lot--in just one day, a sea horse can eat 3,000 shrimp!

    A sea horse keeps the same mate for its whole life, and it's the male(雄的)sea horse that gives birth to baby sea horses. How does this happen? Baby sea horses start out as eggs, which come from the female's body. The male carries the eggs in its pouch for about three weeks until they hatch(孵化). Soon after the babies are born, the female gives her mate a new set of eggs. The male sea horse spends most of its life carrying eggs.

    Sadly, the number of sea horses is becoming smaller. Why is this happening? Some places where sea horses once lived have been filled in to make new land. Also, many sea horses are caught and sold as aquarium（水族馆，养鱼缸）fish. This really is not a good idea because most sea horses don't live long in aquariums. The best place for a sea horse is the ocean.
