Lung Cancer
The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years. It is considerably higher in urban and industrial areas than in rural districts.46Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air (smoke particles, smog,exhaust fumes), and the smoking of cigarettes and cigars.
47Among heavy smokers -- 21 to 30 cigarettes per day -- the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers. It is expected the death rate among women will increase as the present high rate of smoking among women has its effect.
Sometimes cases of lung cancer are discovered at the time an X-ray is taken for the purpose of detecting tuberculosis.48Early detection is absolutely essential if any possibility of cure is to be maintained. Modem X-ray machines in competent hands pose such slight danger, at least to those over 40 years of age that this would be much more than offset by the advantages of discovering a tumor while it is small enough to be completely removed.
49The tumor may grow until the bronchus is blocked, cutting off the supply of air to that lung. The lung then collapses, and the secretions trapped in the lung spaces become infected, with a resulting pneumonia or the formation of a lung abscess. 50 The only treatment that offers a possibility of cure, before secondary growths have had time to form, is to remove the lung completely. This operation is called pneumonectomy.
Malignant tumors of the stomach, the breast, the prostate gland and other organs may spread to the lungs, causing secondary growths.
A. A common form of lung cancer is bronchogenic carcinoma, so-called because the
malignancy originates in a bronchus.
B. Lung cancer, also known as carcinoma of the lung or pulmonary carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung.
C. Too often, however, a current emphasis upon the danger of exposure to radiation from X-ray machines can frighten people away from routine chest X-rays and thus prevent an early diagnosis of lung cancer.
D. Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits.
E. Such a lung cancer can also spread to cause secondary growths in the lymph nodes of the chest and neck as well as in the brain and other parts of the body.
F. There are many possible causes, but it is still controversial which are most blameworthy.
答案與解析
46.F。空格前講的是過去25年肺癌死亡率增加的情況;空格後提到“頻繁提到的因素是接觸異質顆粒和空氣中其他刺激物(煙塵、煙霧、廢氣)，以及抽菸和抽雪茄”，也就是引起肺癌的因素。由此可知，空格處也應談及引起肺癌的原因。故正確答案為F。
47.D。空格後兩旬介紹的都是抽菸與肺癌死亡率之間關係的例子，選項D“一系列研究表明，肺癌的'死亡率與吸菸的習慣之間存在著明顯的關係”是對空格後內容的總結，符合題意。
48.C。空格前一句提到，有時肺癌是在進行x射線檢查結核病時發現的;空格後提到，如果想要保持治癒的可能，儘早發現絕對重要，所以空格處也是一個介紹肺癌的檢查。選項C“但是，當前強調接觸X射線機的放射線的危險常常也使得人們不敢去做常規的胸部X射線檢查，從而不能及早對肺癌做出診斷”，與前後銜接緊密，符合題意。
49.A。空格後提到，腫瘤會一直長到支氣管被堵塞，切斷了空氣向肺的供給，所以空格處的內容應提到腫瘤與支氣管。選項A“肺癌的常見型別為支氣管癌，之所以這樣稱呼是因為惡性腫瘤產生於支氣管內”，符合題意，且前後內容銜接緊密，故選A。
【備考助手】重複詞的出現是體現語義銜接的重要標誌。
50.E。空格後提到，可能治癒的唯一方法就是在繼發腫瘤出現之前將肺全部切除，由此可知，空格處也應介紹繼發腫瘤的情況。選項E“這種肺癌也會擴散，在胸部和頸部淋巴結、腦部以及身體的其他部位繼發再生”符合題意，且與前後銜接緊密。
