The kids in this village wear dirty, ragged clothes. They sleep beside cows and sheep in huts made of sticks and mud. They have no school. Yet they all can chant the English alphabet, and some can make words.

    The key to their success: 20 tablet computers(平板电脑) dropped off in their Ethiopian village in February by a U.S. group called One Laptop Per Child.

    The goal is to find out whether kids using today's new technology can teach themselves to read in places where no schools or teachers exist. The Massachusetts Institute of Technology researchers analyzing the project data say they're already amazed. “What I think has already happened is that the kids have already learned more than they would have in one year of kindergarten,” said Matt Keller, who runs the Ethiopia program.

    The fastest learner—and the first to turn on one of the tablets—is 8-year-old Kelbesa Negusse. The device's camera was disabled to save memory, yet within weeks Kelbesa had figured out its workings and made the camera work. He called himself a lion, a marker of accomplishment in Ethiopia.

    With his tablet, Kelbasa rearranged the letters HSROE into one of the many English animal names he knows. Then he spelled words on his own. “Seven months ago he didn't know any English. That's unbelievable,” said Keller.

    The project aims to get kids to a stage called “deep reading,” where they can read to learn. It won't be in Amharic, Ethiopia's first language, but in English, which is widely seen as the ticket to higher paying jobs.

    Reports tell us that Americans work more and vacation less than people in other major industrial countries. Still, millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.

    For example, many retired Americans can be found driving around the United States in big recreational vehicles, known as R. V.'s. These serve as a home away from home. In fact, it might even be their only home as they see the country.

    Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There, they can experience what life was like for early Americans. If that is not exciting enough, also in Williamsburg is a water park and an amusement park with rides.

    Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing, except maybe read a book.

    Some families fly to other countries on vacation. Or they go on a cruise ship (大型游轮) and stop in different ports. Cruise ships are like floating cities.

    But not everyone goes someplace special on vacation. This might be the only time for people to work on things like home improvement projects. And while they do that, they might think of all the fun their friends are having.

    World Elephant Day is the perfect time to find out more about these amazing animals and what we can do to preserve them so they do not go the way of the mammoth（猛犸象）.

    World Elephant Day was created in 2011 by two Canadian filmmakers Patricia Sims and Thailand's Elephant Reintroduction Foundation and was first celebrated on August 12, 2012. They made the documentary Return to the Forest, a fascinating 30 minute film about the reintroduction of caught Asian elephants to the wild.

    Currently, the demand for ivory（象牙）is becoming bigger and bigger, whose price is higher than that of gold, making elephants bigger targets than ever. Habitation loss is also a danger to the world's elephant population as it robs elephants of the hundreds of pounds of food they need every day, making it more difficult for them to breed and making it easier for hunters to track them down. Circuses and tourism are also serious threats to the animals' well-being.

    The best way to celebrate this day is to take the opportunity to educate yourself about these magnificent（巨大的）mammals and share your knowledge with others. As ever, simply spreading the word about the dangers these magnificent mammals face via social media can actually make a real change. Expose that “training” elephants often involves tying and beating them daily for months on end. If you want to get a bit more involved, you could choose to make a donation to a foundation dedicated to protecting elephants from hunters or relocating them to locations better suited to their needs.

    Whichever way suits you best, make sure that you spend this day in a way that helps elephants all over the world, so we, in turn, can continue to wonder at them and their uniquely fascinating way of life.

    Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

    The first is called the "tank test". A modem airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构)of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. Vne pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

    The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot's job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

    Londoners are great readers. They buy vast numbers of newspapers and magazines and of books-especially paperbacks, which are still comparatively cheap in spite of ever­increasing rises in the costs of printing. They still continue to buy "proper" books, too, printed on good paper and bound (装订) between hard covers.

    There are many streets in London containing shops which specialize in book­selling. Perhaps the best known of these is Charring Cross Road in the very heart of London. Here bookshops of all sorts and sizes are to be found, from the celebrated one which boasts of being "the biggest bookshop in the world" to the tiny, dusty little places which seem to have been left over from Dickens' time. Some of these shops stock, or will obtain, any kind of books, but many of them specialize in second­hand books, in art books, in foreign books, in books on philosophy, politics or any other of the countless subjects about which books may be written. One shop in this area specializes only in books about ballet!

    Although it may be the most convenient place for Londoners to buy books, Charring Cross Road is not the cheapest. For the really cheap second­hand books, the collector must venture off the beaten track, to Farringdon Road, for example, in the East Central district of London. Here there is nothing so impressive as bookshops. The booksellers come along each morning and pour out their sacks of books onto small handcarts. And the collectors, some professionals and some amateurs, have been waiting for them. In places like this they can still, occasionally, pick up for a few pence an old one that may be worth many pounds.

    Anyone who is afraid of failure and afraid to face challenges will never taste success, so said our professor in marketing. I laughed it off at that time, but got frightened when it actually happened in my life.

    I landed in a small city in the Middle East to set up a firm, a world－class car rental firm. Having decided on the project, I earnestly settled in preparation. With a positive mind, I told myself nothing should stop me now, and was more than keen to make it a success.

    However, the least expected thing happened. Iraq invaded Kuwait. Tension ran high in the region. Eventually the war broke out, and many people fled the country, leaving my firm in deep trouble.

    As usual, "things become difficult, and every effort seems to bring disappointment, it can be tempting to lower your expectations or even water down your goals and ambitions." I was no exception. I thought of running away. I remembered the words of Thomas Edison, "Many of life's failures are people who did not realize how close they were to succeed when they gave up."

    I decided to hang on, telling myself, "I am not afraid of challenges and obstacles." I stayed on through months of uncertainty and insecurity. Finances ran low, and banks could not wait to get their dues. To add to all this, the banks even threatened to take all my vehicles. I felt I made a wrong decision to move there. I was now ready to face failure.

    I was living against all hopes, believing that something good would happen. After 2 months the war ended. My persistence paid off: people started flooding back and the car bookings picked up, five times over.

    Success comes to the one who dares, even after failure, to think positively and look forward confidently. After all, it is only the experience that makes a man tough. Failure does not mean you will never make it. It means that it will take a little longer. It provides us with a learning experience.
