Stomach Ulcer
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 ul-cers. 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 heor 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.
In the past， doctors could not do anything about stomach ulcers. 查看材料

听力原文： Hi, there. Let me make a brief introduction of the brain first.
The brain tells the other parts of the body what to do. We think with our brain. We understand the world around us with our brain. However, doctors don't know much about how the brain works. Doctors can do many things with other parts of the body.
They can give a person a new heart. They can put an arm back on 'after it has been cut off. It is easy to study some parts of the body. However, it is difficult to know how the brain works. It is most difficult to work on a brain. If the brain is without enough blood for three to five minutes, the brain dies. So when doctors work on the brain, they only have three to five minutes to do their work] Doctors try new things on the brain, but they must be very careful. The brain is the center of those things that make us what we are.
Which of the following can't doctors do？
A．They can give a person a new heart.
B．They can give a person a new brain.
C．They can put an arm back on after it has been cut off.
How hard is it to get into one of the top medical schools, like for example the one at Yale University in Connecticut？ Last year almost three thousand seven hundred students hoped to get accepted there. Only one hundred seventy-six -- or less than five percent -- were admitted.
People who want to become medical doctors often study large amounts of biology, chemistry and other science. Some students work for a year or two in a medical or research job before they try to get accepted to medical school.
Medical students spend their first two years in classroom study. They learn about the body and all of its systems. And they begin studying diseases -- how to recognize and treat them. By the third year, students guided by experienced doctors begin working with patients in hospitals. As the students watch and learn, they think about the kind of medicine they would like to practice as doctors. During the fourth year, students begin applying to hospital programs for the additional training they will need after medical school. Competition for a residency at a top hospital can be fierce.
A medical education can be very costly, especially at a private school. One year at a private medical college can cost forty thousand dollars or more. The average at a public medical school is more than fifteen thousand dollars. Most students have to take out loans to pay for medical school. Many finish their education heavily in debt.
Doctors are among the highest paid professionals in the United States. Specialists in big cities are generally the highest paid. But there are also doctors who earn considerably less, including those in poor communities.

A、It is hard to get into one of the top medical schools.

Many Older Doctors Plan to Phase out Their Practice
The results of a new survey indicate that 48 percent of physicians between 50 and 65 years of age are planning to reduce or end their clinical practice in the next 1 to 3 years. The findings also suggest that many older physicians believe that their younger counterparts do not have the work ethic they do.
The survey, which was conducted by Merritt Hawkins&Associates, a Texas-based physician search and consulting finn, suggests that many older physicians are simply unhappy with the chan- ges that have taken place in medicine over the years.
"When Baby Boom doctors entered medicine they had control over how they practiced and the fee they charged. But the rules changed on them in mid-stream and now many are looking for a ticket out, "Mark Smith,executive vice president of merritt hawkins&Ass0ciates,said in a statement.
"our study is the only one I am aware of that examines the career plans 0f physicians in the50 -65 age group. "This age group represents more than one-third of all physicians in the U. S. If they stop working in the coming years, it will have a "significant impact" on the overall supply of physicians, Smith told Reuters Health.
The results of the survey,which included 1,170 respondents(调查对象) ,show that 24 per- cent of older physicians are planning to leave clinical practice all together in the next 1 to 3 years. Specifically,14 percent said they were planning on retiring,7 percent said they were looking for a medical job a non-patient care setting, and 3 percent said they were seeking a job in a non-medi- cal field.
For those physicians not leaving clinical practice, many said they would make changes to re- duce the number of patients they treat. For instance,12 percent said they would begin working part-time,8 percent said they planned to stop taking new patients or markedly reduce their patient load, and 4 percent expressed a desire to work on a temporary basis.
When asked about the work ethic of physicians entering practice today,68 percent of the re- spondents said that these younger doctors are not as dedicated or as hard working as physicians who entered practice 20 to 30 years ago.
Fifty-seven percent of older physicians said they would not recommend medicine as a career to their own children. Similarly,44 percent said they would not select medicine as a career if they were starting out today.
"The most ominous(不祥的 )finding is that about one half of physicians surveyed plant to ei- ther abandon patient care in the next 1 to 3 years, or significantly reduce the number of patients they see. "Smith said. "The U. S. already is facing a widespread shortage of physicians, should ol- der, &39; workhorse&39;physicians choose to opt out of patient care access to medical services will be fur- ther restricted.
Which is NOT true of physicians in the 50 -65 age group in the U. S ？ 查看材料
A.They are mostly baby boomers
B.They have nothing to complain about
C.Many of them plan to gradually stop their practice
D.They account for over one-third of all physicians in the country
