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

根据以下材料，回答题

Ward off Travel Bugs

（1） As the holiday season approaches， so does the prospect of jet lag， an upset stomach or sunburn.

With care and some help fi"om natural sources， however， it is quite possible to avoid these problems.

（2） You can start to prepare a couple of weeks before you leave. Food poisoning will make any holiday miserable， but by taking some medicine such as lactobacillus and bifidobacteria， you can reduce the likelihood of poisoning caused by food or water tainted （感染，污染） with unfamiliar bacteria.

（3） By improving the bacteria balance in your digestive tract， you crowd out the pathogenic （病原的）bacteria and stop them gaining a foothold. The beneficial bacteria also produce gentle but effective natural antibiotics （抗生素） in yourgut.

（4） In many holiday locations you need to remember the basics: drink bottled water， avoid undercooked meat and ensure that food hygiene （卫生） is adequate. If you get food poisoning，drink plenty of water to stay hydrated（保持水分）and see a doctor. However， if you detect diarrhea（腹泻） early enough， you might like to try taking about 10 or 15 pancreatic digestive enzymes， which can digest the multiplying bacteria before they take over.

（5） Taking a teaspoon of silicol gel can also help. This lines the stomach and upper intestinal area and binds with bacteria and viruses， allowing them to be safely passed out of the gut. When you pack，include grapefit-it-seed extract， which is an excellent all-round anti-bacterial， anti- parasitic，anti-viral （抗毒的） and anti-fungal （杀菌的） agent.

（6） Your flight can also be made more pleasant. Peppermint oil and ginger capsules （胶囊） ward off motion sickness， but a more delicious option is to eat crystallized ginger. If you tend to get ear-ache on take-off and landing， you can use special ear plugs with filler that slows down the rate of change in air pressure.

（7） The greatest concern is "economy class syndrome"， the popular name for deep-vein thrombosis （血栓症） ， which can lead to blood clots traveling from the legs to the lungs， heart or brain. To reduce this， you need a couple of hours to stay hydrated， and avoid alcohol.

（8） You can also reduce the severity of inflammation by taking a daily gram of vitamin C with the bioflavonoid quercetin. Vitamin C and quercetin also help to reduce prickly heat.

（9） Finally， if any adverse symptoms persist while overseas， you should see a doctor.

根据以下材料，回答题

Einstein Named "Person of the Century"

Albert Einstein， whose theories on space time and matter helped unravel （解决） the secrets of the atom and of the universe， was chosen as "Person of the Century" by Time magazine on Sunday.

A man whose very name is synonymous （同义的） with scientific genius， Einstein has come to represent more than any other person the flowering of 20th century scientific though that set the stage for the age of technology. "The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic， but technological—technologies that flowed directly from advances in basic science，" wrote theoretical physicist Stephen Hawking in a Time essay explaining Einstein"s significance.46______

Time chose as runner-up President Franklin Roosevelt to represent the triumph of freedom and democracy over fascism， and Mahatma Gandhi as an icon （象征） for a century when civil and human rights became crucial factors in global politics.

"What we saw was Franklin Roosevelt embodying the great theme of freedom"s fight against totalitarianism， Gandhi personifying （象征，体现） the great theme of individuals struggling for their rights， and Einstein being both a great genius and a great symbol of a scientific revolution that brought with it amazing technological advances that helped expand the growth of freedom，"said Time Magazine Editor Walter Isaacson.

Einstein was born in Ulm， Germany in 1879.47______ He was slow to learn to speak and did not do well in elementary school. He could not stomach organized learning and loathed taking exams. In 1905， however， he was to publish a theory which stands as one of the most intricate examples of human imagination in history.48______ Everything else——mass， weight， space， even time itself—— is a variable （变量） . And he offered the world his now-famous equation （方程式）:energy equals mass times the speed of light squared——E=mc2.

49______"There was less faith in absolutes， not only of time and space but also of truth and morality." Einstein"s famous equation was also the seed that led to the development of atomic energy and weapons. In 1939， six years after he fled European fascism and settled at Princeton University， Einstein， an avowed pacifist， signed a letter to President Roosevelt urging the United States to develop an atomic bomb before Nazi Germany did. 50______ Einstein did not work on the project. Einstein died in Princeton， New Jersey in 1955.
