Stomach UlcerStomach ulcers are the cause of severe pain for many people.Doctors have been able to help lessen the pain of ulcers.They could not cure them.Now doctors have discovered a cause of ulcers.This means they may have found a way to cure people who suffer from the stomach pain.Studies show that ten percent of the population will develop an ulcer at some time in their life.So a possible cure is good news for many people.Ulcers are wounds in the stomach that are similar to small cuts or tears.These wounds can harm the tissue in the stomach,the pipe that carries the food to the stomach or parts of the small intestines.Fluids in the stomach then increase the pain of an ulcer.How does a person know he or she has an ulcer?Doctors say most people with ulcers feel a burning pain in their chest or stomach.This pain often is called heart burn.It usually happens before eating or during the night.It causes some people to lose their desire to eat,or they are unable to keep food in their stomachs.Doctors believed that ulcers were caused by unusually strong stomach fluids,which damaged stomach tissue.Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H.Pillorie.H.Pillorie bacteria are what make stomach produce extra stomach fluid.Doctors found that they can kill the bacteria with medicines called antibiotics.Health experts say the discovery of a cure for ulcers can save thousands of millions of dollars in medical costs.They also believe curing ui- cers will reduce the number of people who develop stomach cancer.The number of people with stomach cancer is very high in Japan,Southeast Asia and parts of Africa.Doctors say a person is more likely to get an ulcer if his or her family has had one.In fact a person with the family history of ulcers is three times more likely to get one than other peo-ple.There are ways people can protect themselves from developing an ulcer.Doctors say it is more important to reduce the amount of strong fluids in the stomach.To do this,doctors say,people should not smoke cigarettes or drink alcohol.And they say people should reduce tension in their lives.Stomach ulcer can lead to stomach cancer.A:RightB:WrongC:Not mentioned

As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.Experts on dyslexia say that the problem is not a disease.They say that persons with dyslexia use information in a different way.One of the world's great thinkers and scientists,Albert Einstein was dyslexic.Einstein said that he never thought in words the way that most people do.He said that he thought in pictures instead.The American inventor Thomas Edison was also dyslexic.Dyslexia first was recognized in Europe and the United States more than 80 years ago.Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled.The doctors found that the brains of persons with dyslexia are different.In most people,the left side of the brain一 the part that controls language is larger than the right side.In persons with dyslexia,the right side of the brain is bigger. Doctors are not sure what causes this difference.However,research has shown that dyslexia is more common in males than in females,and it is found more often in persons who are left handed.No one knows the cause of dyslexia,but some scientists believe that it may result from chemical changes in a baby's body long before it is born.They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help.After they have solved their problems with language,they often show themselves to be especially intelligent or creative.One out of five American children suffers from dyslexia.A:Right B:Wrong C:Not mentioned

Scientists working on a problem do not know and sometimes can't even guess what the final result will be.Late on Friday,8 November,1895,Professor Rontgen,a German physicist,was doing an experiment in his laboratory when he noticed something extraordinary.He had covered an electric bulb with black cardboard,and when he switched on the current he saw little dancing lights on his table.Now the bulb was completely covered;_________(46)?On the table there were some pieces of paper which had been covered with metal salts.It was on this paper that the lights were shining. Professor Rontgen took a piece of this paper and held it at a distance from the lamp.Between it and the lamp he placed a variety of objects,a book,a pack of cards,a piece of wood and a door key. __________(47).He called his wife into the laboratory and asked her to hold her hand between the lamp and a photographic plate._________(48),but she held up her hand for a quarter of an hour, and when the plate was developed there was a picture of the bones of her hand and of the ring on one finger. The mysterious ray could pass through the flesh and not through the bone or the ring.At a scientific meeting,Professor Rontegen called this new ray "the unknown" the X-ray. _________(49),and soon there were X-ray machines in all the big hospitals.The most obvious use for this discovery was to enable doctors to see exactly how a bone was fractured._________(50).It was found that these rays could be used to destroy cancer cells,just as they destroyed the healthy cells of the doctors who first used the machines.Methods were found later by which ulcers in the stomach could be located,and the lungs could be X-rayed to show if there was any tuberculosis present._______（49）A:The ray penetrated every one of them except the keyB:She was very surprised by this requestC:how then could any ray penetrateD:It was a great inventionE:Other uses came laterF: Doctors quickly saw how this could be used

The Mind-Body ConnectionsNorman Cousins was a famous American magazine editor. In 1964,he returned from an overseas trip and then became very ill.In the hospital,he had a terrible pain and couldn't move his body.Doctors told him he had a serious disease called ankylosing spondylitis（强直性脊柱炎）and said he had only 1 chance in 500 of surviving. They gave him powerful drugs,but his condition only got worse.Cousins had read about a theory that negative emotions can harm your health.He believed that positive emotions were good for one's health,and he decided to try an experiment.He would fill his days with good feelings and laughter and see if that might improve his condition.He left the hospital and moved into a hotel room.There,he got a large supply of funny TV programs and copies of old Marx Brothers movies and cartoons.He also hired a nurse to read funny stories to him.His plan was to spend the whole day laughing and thinking about happy things.On his first night in the hotel,Cousins found that laughing at the movies helped his body produce chemicals that reduced pain.For the first time in weeks,he could sleep comfortably for a few hours.Every time the pain came back,he watched anotherfunny movie and laughed until he felt better.Over time,Cousins was able to measure changes in his body with blood tests.He found that the harmful chemicals in his body decreased at least 5 percent every time he watched a funny movie.After a short time, he was able to stop taking all of his medications.Finally his condition improved so much that he could go back to work.Cousins later wrote a book about how laughter and happiness helped him to survive a deadly illness. Many people didn't believe his story and said that his doctors were wrong about his disease.But since then, research has found that emotions do have a strong effect on physical health,and experiments found that laughter can help to reduce pain.Scientists today are working to understand the ways that our minds affect our bodies.Doctors told Cousins that he would probably die from his disease.A:RightB:WrongC:Not mentioned
