Stomach 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 ulcers 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 people. 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.

1Every year earthquakes are responsible for a large number of deaths and a vast amount of destruction in various parts of the world. most of these damaging earthquakes occur either in a narrow belt which surrounds the Pacific Ocean or in a line which extends from Burma to the Alps in Europe. Some of the destruction is directly caused by the quake itself. An example of this is the collapse of buildings as a result of the quake itself.Other damage results from landslides or major fires which are initiated by the quake.
2These are about a million quakes a year. Fortunately, however, not all of them are destructive. The intensity of an earthquake is measured on the Richter Scale, which goes from 0 upward. The highest scale recorded to date is 8.9. major damage generally occurs from quakes ranging upward from 6.0.
3The actual cause of the quake itself is the breaking of rocks at or below the earth\'s surface. This is produced by pressure which scientists believe may be due to a number of reasons, two of which are the expansion and contraction of the earth\'s crust and continental drift.
4In order to limit the damage and to prevent some of the suffering resulting from earthquakes, scientists are working on ways to enable accurate prediction. Special instruments are used to help people record, for example, shaking of the earth. Scientists are trying to find methods that will enable them to indicate the exact time, location and size of an earthquake.
5Certain phenomena have been observed which are believed to be the signs of imminent earthquakes. These include strange behaviors of some animals, the changes in the content of mineral water, etc.The magnetic properties of rocks may also display special pattern before earthquakes happen.

attitudes to AIDS now Most people say that the USA is making progress in fighting AIDS．but they don’t know
there’S no cure and strongly disagree that“the AIDS epidemic is over．”a new survey finds．
The findings，released Thursday by the Kaiser Family Foundation，reassure activists who have worried that public concern about AIDS might disappear in light of recent news about advances in treatment and declines in deaths．
“While people are very optimistic about the advances．they’re still realistic‘about the fact that there is no cure”，says Sophia Chang，director of HIV programs at the foundation．
The Kaiser survey，like a recent USA TODAY Gallup Poll，does find that the number of
people ranking AIDS as the country’s top health problem has fallen．In the Kaiser poll，38％say it’s the top concern，down from 44％in a 1996 poll；in the Gallup Poll，29％say AIDS is No．1，down from 41％in 1992 and 67％in 1987．
Other findings from Kalser，which polled more than 1,200 adults in September and 0ctober
and asked additional questions of another 1,000 adults in November：
52％ say the country is making progress against AIDS；up from 32％in 1995．
51％ say the government spends too little on AIDS．
86％ correctly say AIDS drugs can now lengthen lives；an equal number correctly say that the drugs are not cures．
67％ incorrectly say that AIDS deaths increased or stayed the same in the past year；24％ know deaths fell．
Daniel Zingale，director of AIDS Action Council，says，“I’m encouraged that the American
people are getting the message that the AIDS epidemic isn’t over． I hope the decision-makers In Washington are getting the same message…We have seen signs of complacency．”
