回答题：

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

第5题

People from large families have an increased risk of stomach cancer, suggests a study that

followed more than 7,000 Japanese-American men for 28 years.

The study concluded that family size had a major influence on the development of stomach cancer linked to the bacterium Helicobacter pylori (幽门螺杆菌), and that younger siblings (兄弟，姐妹，同胞，同属) from large families were especially prone to the most common form. of stomach cancer.

H. pylori lives in the mucous (黏液的) layer of the stomach and is associated with peptic ulcers (消化器官溃疡) and stomach cancer. It's estimated that half of the world's population carries H. pylori in the stomach. It can be transmitted orally from person to person or through contact with human feces (粪便).

The study found that men who carried certain strains of H. pylori in their stomachs and had seven or more siblings had more than twice the risk of developing stomach cancer, compared to men with the same H. pylori strains who had one to three siblings.

The findings are published in the January 16 online issue of the journal Public Library of Science Medicine.

"This is a very carefully controlled study that clearly shows that there are factors in early childhood that affect the risk of developing cancer many decades later," study leader Dr. Martin J. Blaser, professor and chairman of the Department of Medicine, and professor of microbiology at New York University Medical Center and School of Medicine, said in a prepared statement.

"That early childhood events affect the risk of cancers occurring in old age is remarkable, and this may be a model for other cancers," Blaser said. He said that younger children in large families may acquire H. pylori from older siblings at a time when the younger children's immune systems are still developing. This, in combination with the fact that the bacterium is already adapted to a genetically related person, means the younger children may have a more virulent H. pylori population in the stomach than if they'd acquired the germ from a non-relative.

Which of the following statements can best generalize the passage？

A．Family size may determine stomach-cancer risk.

B．Family size may move stomach-cancer risk.

C．The study may follow more than 7,000 Japanese-American men for 28 years.

D．People from small families have an increased risk of stomach cancer.

Scientists working on a problem do not know and so...

Scientists working on a problem do not know and sometimes can&39;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. (46) ; how then could any ray penetrate？ On the table there were some pieces of paper which had been covered with metal salts. (47) . 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 books, a pack of cards, a piece of wood and a door key. The ray penetrated every one of them except the key. 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. Other uses came later. 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. (50) , and the lungs could be X-rayed to show if there was any tuberculosis present.

A. It was on this paper that the lights were shiningB. She was very surprised by this requestC. Now the bulb was completely coveredD. It was a great inventionE. Methods were found later by which ulcers in the stomach could be locatedF. Doctors quickly saw how this could be used

第9题

Cultures tend to favor either a past, or future orientation with regard to time. A future

orientation, encompassing a preference for change, is characteristic of American culture. The society encourages people to look to the future rather than to the past. Technological, social, and artistic trends change rapidly and affect people's life styles and their relationships.

Given the inclination toward change, it is not surprising that tradition plays a limited role in the American culture. Those who try to uphold traditional pattern of living or thought may be seen as rigid or "old-fashioned". In a society where change is so rapid, it is not uncommon for every generation to experience a "generation gap". Sometimes parents struggle to understand the values of their children, even religious institutions have had to adapt to contemporary need of their followers. Folk singers in church services, women religious leaders, slang versions of the Bible, all reflect attempts made by traditional institutions to "keep up with the times".

High rates of change, particularly in urban areas, have contributed to a focus on the future rather than the past or present. Some Americans believe that the benefits of the future orientation are achievement and progress which enable them to have a high standard of living. Others believe that high blood pressure and stomach ulcers are the results of such a life style.

As individuals in a culture, we all have an intuitive understanding about how time is regulated, usually we do not think about the concept of time until we interact with others who have a different time orientation. Although individuals from any now cultures may view time similarly, we often sense that in another culture, life seems to proceed at either a slower or faster pace. Knowing how time is regulated, divided, and perceived can provide valuable insights into individuals and their culture.

The American orientation toward the future might be demonstrated by ______.

A．the presence of religious institutions

B．the preference for "old-fashioned" parents

C．the limited role of tradition

D．the presence of folk singers in church services

A daily dose of aspirin can prevent cancer in people with a genetic disorder that increase

s their risk of developing the disease, scientists said on Monday.

The finding could also have important implications for the wider population, although more research is needed and unraveling the connection will take some time since the benefits of aspirin were only seen after several years.

John Burn of the Institute of Human Genetics at Newcastle University in Britain said his study might also have uncovered a simple way of controlling stems cells that make tumors grow.

"We believe that aspirin may have an effect on the survival of aberrant (异常的) stem cells in the colon," Burn said, presenting his findings at the ECCO-ESMO European cancer congress in Berlin.

Burn and colleagues tested 1,071 people with Lynch syndrome (林奇综合症) — an inherited condition that predisposes a person to a range of cancers, particularly of the colon — by giving some of them aspirin and some a placebo (实验对照药).

Follow-up tests after 10 years showed that although there was no difference in cancer rates after 29 months, a significant difference was detected after four years, with fewer people in the aspirin group developing colon cancer, Burn said.

"To date, there have been only six colon cancers in the aspirin group as opposed to 16 who took placebo," he added.

Burn said that although people in the trial stopped taking aspirin, its effect clearly continued.

Colorectal is the second biggest cause of cancer death in the United States and Europe, where a total of 560,000 people develop the disease each year, and 250,000 die from it.

Aspirin, originally developed by Bayer, is a cheap over-the-counter drug which in low daily doses has been found to stave off the risk of heart attacks and strokes, as well as chase away occasional aches and pains.

Other scientists have previously found it can reduce the risk of developing colon cancer and suggested it does so by blocking the COX-2.

But Burn said he thought this explanation was unlikely, and thinks that aspirin hits faulty stem cells before they mutate into pre-cancerous cells.

"If aspirin reduced the chances of such cells surviving, this would explain our results," he said.

Despite its benefits, aspirin is also well known for causing stomach upsets. In the study, 11 patients on aspirin had stomach bleeds or ulcers (溃疡) compared with nine on placebo.

The team plans a further study using a larger group of patients taking differing aspirin doses.

According to the passage, which one is irrelevant to the finding of John Burn's study？

A．Aspirin may offer a simple way to control stems cells that make tumors grow.

B．Aspirin may influence the survival of aberrant stem cells in the colon.

C．Aspirin may damage faulty stem cells before their mutation.

D．Aspirin may reduce the risk of developing colon cancer by blocking the COX-2.
