参考解析
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。

共用题干Cooking Oil Fumes Cause TumorThe leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking,said medical experts after a five-year research study.Doctors announced the results yesterday with analysis on some new tendencies in lung cancer. They said patients are younger,especially women.According to the Shanghai Tumor research Institute,more local residents die of lung cancer in the city than anything else.Following breast cancer,it has the second-highest incidence rate.“An unhealthy lifestyle is a very important reason for lung cancer,”said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.He followed 2,276 lung cancer patients for five years.Among them,1,483 were male.Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke,according to the report.However,more than 60 percent of women with the disease had long term,close contact with strong oil fumes from cooking and complained about irritated eyes and throat.About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women's bedrooms were adjacent to the kitchen.However,local women were surprised to learn cooking oil fumes could lead to cancer.Some claimed they may change food preparation methods.“Unless my family and I don't eat at home every day,I must stay in the kitchen to cook,”said Xu Li,a 45-year-old local woman. “I know the fumes are bad for the skin,but it is the first time I heard that it can result in lung cancer. I have already started frying less.”Doctors said women's lung cancer had few links to personal health and physical condition,but was closely related to family cancer history,unhealthy dietary habits and weak immune systems.Other experts agreed with him.“Smoking is by far the biggest cause of lung cancer for men,”said Dr Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University's Medical College.“It's true that second-hand smoke and cooking fumes are the main causes among women.”His research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.The chance of catching lung cancer is three times higher if exposed to the fume for a long time,6 experts said.What a new tendency in lung cancer is concluded by the researchers?A: Men are more likely to develop lung cancer than women.B: Women are more likely to develop lung cancer than men.C: Patients with lung cancer become older,especially males.D: Patients with lung cancer become younger,especially females.

共用题干Lung Cancer1 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.The more cigarettes one smokes,______.A:before the cancer cells spread elsewhereB:the more chances of dying of X-ray radiation he will haveC:what is most responsible for lung cancerD:as some people imagineE:the more chances of getting lung cancer he will have F:which form of lung cancer is a common one
