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 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 lives.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 chests or stomachs.This pain is often called heartburn.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 Pilorie.H Pilorie 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 someone in 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.
选项 There has been a change in doctors'understanding of the cause of stomach ulcers.
A:Right
B:Wrong
C:Not mentioned
答案A
解析由文章第一段的第二、三句“Doctors have been able to help lessen the pain of ulcers.They could not cure them.”可知，过去，医生们虽然不能治愈胃溃疡，但可以减轻胃溃疡造成的疼痛。 故B为正确答案。
由文章第一段的内容可知，医生们发现了一种能引起胃溃疡的病因，这有可能使医生 们找到治愈此病的方法，但这只是一种可能性。故B为正确答案。
由文章第一段倒数第二句“Studies show that ten percent of the population will develop an ulcer at some time in their lives.”可知，全世界百分之十的人口在其一生中会得胃溃疡。故A 为正确答案。
文章前两段只是说医生们找到了一种引发胃溃疡的病因，但并没有提及发现这种病因 耗费的时间或者过程。故C为正确答案。
由文章第二段的倒数第六句“Now they have discovered that most ulcers are caused by a bacterial organism called Hillico Bactor Pilorie or H Pilorie.”可知，现在医生们发现胃溃疡是一种 细菌导致的，这是医生对胃溃疡病因理解的改变。故A为正确答案。
借助常识和背景知识判断该句的说法正确，所以答案可能为“正确”或“没提到”。借助 题干中的特征词stomach cancer作为答案线索词，这样在第2段的结尾部分找到答案相关句 (They also believe curing ulcers will reduce the number of people who develop stomach cancer．他们 相信治愈溃疡能够减少胃癌的认输），确认题干句的说法正确。
借助题干中的spicy food作为答案线索词，发现文章中根本没有谈到spicy food，所以判 断该题的说法为“没提到”。
