问题 共用题干Promising Results 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-three patients suffering from
lung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in the
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.The vaccine cured all the participants in the trial.A:RightB:WrongC:Not mentioned
选项 The vaccine cured all the participants in the trial.
A:Right
B:Wrong
C:Not mentioned
答案 B
解析 题意：该疫苗治愈了参加试验的所有患者。文章第一段最后一句话“cured lung cancer in some patients and slowed the progress of the disease in others.”意思是有些患者被治愈了，有些 是病情得到缓解，由此可判断题干叙述错误。故木题选B。
题意：超过四十人参加了这个试验。根据文章第二段第二句“Forty-three patients suffer- ing from lung cancer were involved in these trials.”可知，参加实验的有43人，所以题干叙述正 确，故本题选A。
题意：试验中，处十癌症早期的患者恢复的更快。根据文章第二段最后两句“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 theearly stages of the illness.”可知，癌症晚期的患者注射疫苗后有很大变化，癌症早期的没有多大起色，所以题干叙述错误，故本题选B。
文章中说科学家做实验的地点在Dallas，没有提及病人来自哪里，故选C。
题意：每个患者注射的都是一样的疫苗。从第三段的前两句话“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.”可知，每支疫苗都是根据患者的免疫系统研究出来的，所以疫苗是不同的，因此答 案选择B。
由文章第三段最后一句话“It stimulates the body' s immune system, which then recognizes that the cancer cells are harmful, and attacks and destroys them.”可知，这种疫苗会刺激身体里的 免疫系统，然后免疫系统辨认出身体里的有害癌细胞，攻击并摧毁它们。题干中activate的意 思是“激活”，与此句意思相符。故选A。
题意：疫苗可能能够在治疗其他癌症上发挥作用。根据文章最后一段第一句“The vac-cine could be effective against other forms of cancer.”可知，题干叙述正确，故本题选A。第3部分：概括大意与完成句子
