共用题干Lung Cancer
1 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.There are many possible causes,but it is still controversial which are most blamewor-thy.Those 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.
2 Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits.Among 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 that the death rate among women will increase as the present high rate of smoking among women has its effect.
3 Sometimes cases of lung cancer are discovered at the time when an X-ray is taken for the purpose of detecting tuberculosis.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.Early detection is absolutely essential if any possibility of cure is to be maintained.Modern 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 com-pletely removed.
4 A common form of lung cancer is bronchogenic carcinoma,so-called because the malignancy originates in a bronchus.The 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 re-sulting pneumonia or the formation of a lung abscess.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.The on-ly treatment that offers a possibility of cure,before secondary growths have time to form,is to remove the lung completely.This operation is called pneumonectomy.
5 Malignant tumors of the stomach,the breast,the prostate gland and other organs may spread to the lungs,causing secondary growths.Paragraph1______ A:Common Secondary Lung CancersB:The Adwintages Brought About by Routine Chest CheckupC:Relationship Between Mortality Rate From Lung Cancer and Smoking HabitsD:Operable and Inoperable Lung CancersE:The Increasing Death Rate From Lung Cancer and Possible CausesF:An Ordinary Type of Lung Cancer

答案
E
解析
文章第一段主要陈述了在过去的25年中男性肺癌患者的死亡率上升了8倍多,女性肺癌患者的死亡率也增加了一倍,并且城市和工业区的肺癌死亡率比农村地区的高。接着又陈述了引起此种情况的原因。故本题选E。
第二段的第一句便引出了该段的主题,即抽烟与肺癌死亡率之间有着紧密的关系。接下来举例证明该论点。故本题选C。
第三段开头指出有时肺癌是在用x射线检查结核病时被发现的,然后通过分析指出常规x射线检查利大于弊。由此可知,本题应选B项。
第四段第一句指出支气管癌是常见的一种肺癌,接着又描述了该癌症的形成过程及其在身体的其他部位引起的并发症等内容。整段都是对支气管癌这种常见肺癌的介绍。故本题选F。
由文章第三段第二、四句的内容可知,人们常因怕被辐射到而不做胸部x射线检查,但现代x射线机在合格技师的操作下所产生的危险微乎其微,并不像通常人们想象的那样,故选D。
由文章第四段第五句可知,在继发肿瘤出现之前将肺切除是治愈肺癌的唯一方法,故选A。
由文章第一段第三句的内容可知,导致肺癌的原因很多,但关于什么是最主要的原因仍存在争议,故选C。
由文章第二段第二句的内容可知,每天抽21到30支烟的重度吸烟者因患肺癌而死亡的几率是不抽烟者的17倍。故本题选E。第4音肠分:阅读理解第一篇本篇文章主要介绍了大脑在人睡眠过程中进行记忆整理的科学发现,以及两个相关实验。
