[Q]: Article: Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue's rareness and age, collectors have paid as much as $16 800 for it.

[Q]: Article: A person who is deaf when he is born is usually dumb as well. There may be nothing wrong with his mouth and tongue, but he cannot speak. This is because he cannot hear people, so he has nothing to imitate . He may try to make sounds himself, but cannot hear his own voice. However, even though he finds it difficult to speak and cannot hear, he can learn to read. Nowadays such persons can also be taught to speak because we have modern methods and equipment, but we did not have these when Helen Keller was born. Even with modern methods and equipment, however, it is not easy for deaf children to learn to speak, though most of them succeed. When a child is deaf and blind as well, it becomes much more difficult, though it is possible. Helen Keller was born in 1880. She became very ill at the age of nineteen months. Medical knowledge was not as great then as it is now. She did not die but lost her sight and hearing. As a result, she became dumb as well. Her parents did their best to teach her, but she couldn't speak by the age of six. Then, in 1887, a teacher, Miss Sullivan, came to live with her. Miss Sullivan herself had been blind. She had been partly cured. Though she could not see very well, she was not blind. Helen was a difficult pupil at first, but in a month Helen had learned how to understand signs and how to make them herself. At last in spite of her great difficulties, Helen learned to read, write and speak, even though she was deaf and blind. She even went to college and had full education. She wrote many books, and though other people have written books about her, her own books are the ones that best explain how it feels to be deaf, dumb and blind. Her best book is The Story of My Life. Perhaps you have read it. Though it was written in 1902, it is still a very interesting book. Even if you have not read it, you may have heard of Helen Keller.

[Q]: Article: Air travel makes some people very nervous. The crowds, the noise and flying itself can cause unease. But there are classes that people can take to help them defeat the fear of flying. And now we are going to talk about similar training for service dogs that suffer from the same problem. Service dogs almost never leave the side of the people they care for. You will see them working on buses, trains and other public transport systems. But the busy environment in an airport can trouble even the best trained working dog. People with disabilities depend on their dogs. They also need the dogs to remain calmly on duty on the airplane, even when the flight is not smooth. This takes special training. The Air Hollywood K9 Flight School is one place where such help can be found. The school has a piece of equipment that provides the sights, sounds and even the feel of an airplane in flight. It is called a flight simulator . The simulator was built for filming airplane scenes in movies. Sandy Alexander lives in Newport Beach, California. He has a disability that requires his two-year-old dog, Doc, to be always at his side. Mr. Alexander took the dog to the flight school to get him ready for plane trips. He says Doc did not like the bumpy part of the flight simulation. "When that started he was pretty _ and looked up at me and wasn't sure what was gong on." "Dogs need to be exposed gradually and repetitively to stimulation, to the environment, to loud noises, to sounds and other dogs so that when this experience happens to them on a daily basis, they are able to act in a way that they are used to acting and don't get excitable," days dog trainer, Mary Segall. Dog owners who have attended the training say they now feel much more at ease about future flights. Their dogs also seem ready for take-off.
