问题 共用题干Promising Resnlts from Cancer Study
A new experimental vaccine（疫苗）has shown promising results in the fight against lung cancer.In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.
Researchers have reported encouraging findings from this small study.Forty一three patients suffering from lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in tho advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.
This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.It stimulates（刺激）the body's immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.
The vaccine could be effective against other forms of cancer.It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.
选项 The vaccine cured all the participants in the trial.A:RightB:WrongC:Not mentioned
答案B
解析阅读下面这篇短文，短文后列出了七个句子，请根据短文的内容对每个句子作出判断。如果该句提供的是正确信息，请选择A；如果该句提供的是错误信息，请选择B；如果该句的信息文章中没有提及，请选择C。 【解析】 题干意为“疫苗治愈了所有参与试验的人。”关键词是cured。依据此关键词，可在文中第一段第二句找到相关叙述：“In a small Texas-based study, a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.”（位于美国达拉斯的贝勒大学医学中心的几位科学家研制出了一种疫苗，这种疫苗在一个基于德克萨斯州的小型研究中治愈了一些肺癌患者，减缓了其他患者的病情发展过程。）由此可见，这种疫苗并没有治愈所有参与实验者，故此题说法为“错误”的。 题干意为“超过四十人参与了这次研究。”关键词是forty。依据此关键词，可在文中第二段第二句找到相关叙述：“Forty-three patients suffering from lung cancer were involved in these trials.”（四十三个肺癌患者参与到这些试验中。）由此可见参与人数确实超过了四十人，故此题说法为“正确”的。 题干意为“在试验中，处于疾病早期的患者恢复得更快。”关键词是the early stages和recovered。依据此关键词，可在文中第二段最后两句找到相关叙述：“In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.”（晚期患者中有三名患者的疾病消失，其他患者的病情在5 到24个月内没有扩散。然而，处于疾病早期的患者没有出现任何不同。）可见这种疫苗对晚期患者的效果比较明显，故此题说法为“错误”的。 题干意为“所有患者都来自达拉斯。”关键词是Dallas。依据此关键词，可在文中第一段第二句找到相关叙述：“In a small Texas-based study, a vaccine developed by scientists at Baylor University Medical Centre in Dallas,USA,cured lung cancer in some patients and slowed the progress of the disease in others.”（位于美国达拉斯的贝勒大学医学中心的几位科学家研制出了一种疫苗，这种疫苗在一个基于德克萨斯州的小型研究中治愈了一些肺癌患者，减缓了其他患者的病情发展过程。）由此可知，研制疫苗的科学家都来自位于达拉斯的贝勒大学医学中心，而病人是不是都来自达拉斯，这一点文中并没有提到，故此说法为“未提及”的。 题干意为“每一个病人都被注射同样的疫苗。”关键词是the same vaccine。 依据此关键词，可在文中第三段第一句、第二句找到相关叙述：“This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg.”（这种新型疫苗使用了人体自身的免疫系统。每个病人的疫苗都是专门制造，然后被注射到手臂或腿上。）由此可见每个患者的疫苗都是不一样的，故此题说法为“错误”的。 题干意为“这种疫苗激活了免疫系统。”关键词是activates。依据此关键词， 可在文中第三段第三句找到相关叙述：“It stimulates the body's immune system, which then recognizes that the cancer cells are harmful, and attacks and destroys them.”(疫苗能刺激人体免疫系统，使免疫系统意识到癌细胞是有害的，从而攻击和破坏它们。）由此可见这种疫苗是通过激活免疫系统发挥作用的，故此题说法为“正确”的。 题干意为“这种疫苗或许可用于治疗其他癌症。”关键词是other cancers。 依据此关键词，可在文中第四段第一句找到相关叙述：“The vaccine could be effective against other forms of cancer.”（这种疫苗或许可以有效地对抗其他癌症。）由此可知，它是可以用于治疗其他癌症的，故此题说法为“正确”的。
