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 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.

参考答案：
1.B.该句从句意上判断是概括总结句，所以推测很可能该题的解答需要考生根据有关句子进行推断。在第一段找到直接答案相关句(Doctors have been able to help lessen the pain of ulcers. 该题考察完成时态的结构含义--动作/状态从过去开始持续到现在, 该划线句的含义是“医生已经能够帮助减少溃疡造成的痛苦”)，判断问题句的说法错误。
2.B.根据常识判断该句的说法不正确。该句在句意上与上题有关：一个说过去的情况，一个说现在的情况，因此注意从上一题的答案相关句的位置往下找。同时注意到问题句中出现了修饰词successfully，所以留意文章中有没有这个词出现，结果发现文章中没有这个词，也没有这个词的近义词出现。所以推测可能该题也是需要考生进行推断。在第一段找到答案相关句(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.该句说“这就意味着他们可能已经发现治疗那些遭受到胃痛困扰的人的方法”，不难看出问题句说的“能成功治愈”与该句的内容不一致)，判断问题句的说法错误。
3.A.该句的说法客观，所以凭借直觉判断该题的说法可能是正确或没提到。借助原文：借助题干中的时间状语at some time in their life作为答案线索词，这样在第1段中(与上一题的答案相关句相近)找到该题答案相关句(Studies show that ten percent of the population will develop an ulcer at some time in their life.)，判断该题正确(时态与句意均一致)。
