Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle. Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine. Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing Jane Eyre. To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious ,but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is... Thomas Edison is spoken of because  _  . A) he also tried to invent a sewing machine B) he got some of his ideas from dreams C) he was one of Howe's best friends D) he also had difficulty in falling asleep

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. The flight simulator  _  . A) can help people to learn how to fly an airplane B) was built for filming airplane scenes in movies C) can't provide the feel of an airplane in flight D) let service dog owners experience the thrill of flying
