　　Promising Results from Cancer Study

　　A new experimental vaccine 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.

　　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 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.

　　答案与解析

　　16.B。题干：该疫苗治愈了所有参加试验的患者。从第二段最后一句可知有些患者被治愈了，有些是病情得到缓解，因此题干内容有误，故选B。

　　17.A。题干：超过四十人参加了这个试验。从第二段第二句可知，参加实验的有43人。因此题干内容正确，故选A。

　　18.B。题干：试验中，处于癌症早期的患者恢复得更快。从第二段最后两句可知，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。因此题干内容有误，故选B。

　　19.C。题干：所有患者都来自达拉斯。从第一段第二句可知，疫苗是达拉斯一所大学的医疗中心研究出来的，但并没有提到患者来自哪里。因此答案为C。

　　20.B。题干：每个患者注射的都是一样的疫苗。从第三段前两句可知每支疫苗都是根据患者的免疫系统(immune system)研究出来的，所以疫苗是不同的。因此题干内容有误，故选B。

　　21.A。题干：疫苗激活了免疫系统。从第三段第三句可知，它能刺激(stimulate)人体的免疫系统，然后识别癌症细胞是有害的，继而攻击和破坏这些癌细胞。因此题干内容正确，故选A。

　　22.A。题干：疫苗可能在治疗其他癌症上发挥作用。根据文章第一段“…cured lung cancer in some patients and slowed the progress ofthe disease in others.”和第四段最后一句“It offers great hope for the treatment of cancer in general，although further studies are needed before such treatment can be widely used.”可知，题干叙述正确，故选A。
