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 patients 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.

答案解析:
16 B 文章第二段提到有三位晚期癌癥患者的疾病消失,而其他人的癌細胞持續5 ~ 24個月沒有擴散,但早期癌癥患者沒有什么療效。題干說疫苗將所有被試者的癌癥都治好,與文章本意不符。
17 A 文中第二段提到有43位肺癌患者參與到這項試驗中,因此本文題干表達的意思符合文章本意,選擇答案A。
18 B 文中第二段最后一句話提到然而早期肺癌患者沒有出現什么不同,而題干說“早期癌癥患者恢復地更快”,與文章本意不符。
19 C 文章第二段只說有43位肺癌患者參與到這項試驗中,并沒有說他們都來自達拉斯,因此本題的答案應是選項C,“沒有提及”。
2 2 B文章第三段第二句話說它是為每一位病人特制的,注射到胳膊或腿上,而題干說每位患者注射同樣的疫苗,與文章本意不符。
21 A文章第三段最后一句話提到“它(疫苗)刺激身體的免疫系統”,因此本文題干表達的意思符合文章本意,選擇答案A。
22 A 文章第四段第一句話提到此疫苗可能會有效抵抗其他形式的癌癥,因此本文題干表達的意思符合文章本意,選擇答案A。
