    Two weeks before my 12th birthday, my teacher asked me to conduct an experiment. When I mixed some powder together, they exploded. Molten liquid hit me in the face, but I felt no pain.

    I vividly remember standing there in a state of calm. I thought I was in a dream, but however hard I struggled to swim to the surface of consciousness, I couldn't wake up. I didn't understand how terrifying it was until I heard people saying, ＂Who's that?＂ That's when I knew I was unrecognizable.

    I was taken to hospital, but the doctors didn't know what to do with me. Later I was flown to Houston for surgery. Between the ages of 13 and 16, I had 40 operations. As each operation came and went, my vision would come back, then fade again. Eventually, it faded completely and I had what was left of my eyes removed for cosmetic reasons.

    Since then, I have lived in total darkness. Most blind people, even if they don't have any sight they're aware of, are still able to sense light. That gives them a sense of day and night. But not me. I absolutely lost that sense of time passing.

    For many years, I felt my sight loss darkening my life like the loss of my parents from which I would never recover. But when I was in my 40s, I realized I had to find a way to live. I trained to become a counselor, and that has helped me see my experiences in a different way. I can't fix people's broken lives — just like I can't fix my sight — but I can help them find a way to manage.

    Sometimes it feels as if all the struggles and negative experiences I've lived through were in fact a kind of preparation for helping others to make their own way towards the light.

    Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws(爪) on its wings when young. They build their homes about 4.6m above the river, an important feature(特征) for the safety of the young. It is called the hoatzin(麝雉).

    In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.

    Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak(喙), they can climb about in the bushes, looking very much like primitive birds. When the young hoatzins have learned to fly, they lose their claws.

    During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.

    Children's books are everywhere. New ones, old ones, made-into-movie ones. It seems as if the children's publishing industry is developing rapidly. Here are some books every young child should have in their book diet.

    The Peter Rabbit books by Beatrix Potter

    It's best to have a copy of the original stories, with the original drawings done by Beatrix Potter herself. In The Tale of Peter Rabbit are the delightful tales of Peter Rabbit. Included in the series are also cute little stories about mice. These books have sweet stories that teach lessons.

The Cat in the Hat by Dr. Seuss

    Dr. Seuss is, of course, the master of children's literature. Dr. Seuss teaches children to play with language and have a good time reading. The pictures are wonderful and inspire lots of fun questions. Big kids will like re-reading Dr. Seuss along with their younger sisters and brothers.

Make Way for Ducklings by Robert McCloskey

    The story of Mr. and Mrs. Mallard is shown by simple pencil drawings that help children use their imaginations. The story explores the city of Boston as the Mallards look for a place to get their ducklings safely across the city. Jack, Kack, Lack, Mack, Nack, Ouack, Pack, and Quack are good examples of obedience(顺从) as they follow Mrs. Mallard through the city.

The Very Hungry Caterpillar(毛虫) and other books by Eric Carle

    The Eric Carle books have delightful pictures, full of bright colors and interesting detail. In The Very Hungry Caterpillar, children see the life cycle of a butterfly through the eyes of a caterpillar that is hungry. The children will laugh at all the food the caterpillar eats and be overjoyed by the beautiful butterfly at the end. All the Eric Carle books are fun for kids and parents, with simple ideas and beautiful art.

    There are many children's books available, and this list is only the beginning. However, these are all essential to a good children's library.

    A Swiss airplane powered only by energy from the sun left from Abu Dhabi early on March 9. Its creators hope the plane will make the first around-the-world journey without any fuel. The plane is called Solar Impulse 2. It has one seat and is made from carbon fiber. The plane weighs only as much as a car but its wings are wider than a Boeing 747. The plane's wings stretch 72 meters across. Those wings include 17,000 solar units, or cells, which capture the sun's energy. The energy allows the plane to fly day and night.

    Two Swiss scientists built the plane. Bertrand Piccard is also an explorer who made the first non-stop flight around the world in a balloon. Andre Borschberg is an engineer and trained fighter pilot. The scientists say they are not trying to alter the airplane industry. Instead, they want to show that new energy sources and technologies can achieve what some say is impossible. “We want to show we can fly day and night in an aircraft without a drop of fuel.” Mr. Piccard said.

    Some parts of the trip will require the pilots to be in the tiny plane for five to six days and nights in a row. So it is good that the pilot's seat is also a toilet.

    The plane's route begins in the United Arab Emirates. The pilots also plan stops in Oman, India, and China. They will cross the Pacific Ocean, stop in the United States, and continue over southern Europe or North Africa. They plan to arrive back in the United Arab Emirates in late July or early August.

    Internet viewers can go to the Solar Impulse website to see the plane's location and listen to broadcasts from the pilots.

    The purpose of a map is to express graphically the relations of points and features on the earth's surface to each other. These are determined by distance and direction. In early times distance was often expressed in units of time, for example “so many hours' march” or “a day's journey by river”, but such measurements gave more information about the relative ease of crossing the local terrain than they did about actual distance. The other element is direction, but for the ordinary traveller, whose main concern was “Where do I go from here?” and “How far away is it?”, the accurate representation of direction was not of primary importance. Partly for this reason, written itineraries (行程) for a long time rivaled maps. Even today, certain types of maps, for example, those showing railway systems, may make little attempt to show true directions. Similarly, obvious landmarks along a route were at first indicated by signs, realistic or conventional (惯常的), and varied in size to indicate their importance. Clearly the conventions employed varied with the purpose of the map, and also from place to place, so that in studying early maps the first essential is to understand the particular convention employed.

    The history of cartography (制图) is largely that of the increase in the accuracy with which these elements of distance and direction are determined and in the comprehensiveness of the map content. In this development, cartography has called in other sciences to its aid. For example, instead of determining direction by observing the position of a shadow at midday, or of a constellation (星座) in the night sky, or even of a steady wind, use was made of terrestrial magnetism (地磁学) through the magnetic compass, and instruments were evolved which enabled horizontal angles to be calculated with great accuracy.

    The application of astronomical concepts, and the extension of the knowledge of the world through exploration, encouraged attempts to map the known world. Then astronomers discovered that the earth is not a perfect sphere, but is flattened slightly at the poles, which introduced further refinements into the mapping of large areas. Meanwhile, the demands being made of the map maker were shifting significantly. The traveller or the merchant ceased to be the sole user of maps. The soldier, especially after the introduction of artillery, and the problems of range, field of fire, and dead ground which it raised, demanded an accurate representation of the surface features, in place of the earlier conventional or pictorial delineation (描绘), and a solution in any degree satisfactory was not reached until the contour (等高线) was invented.
