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 blameworthy.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 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 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 completely 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 resulting 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 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.5 Malignant tumors of the stomach,the breast,the prostate gland and other organs may spread to the lungs,causing secondary growths.People are still not sure______.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 haveF:which form of lung cancer is a common one
共用题干Promising Results From Cancer StudyA 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 fromlung 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 patient's own immune system.It is made specifically for each patient and is injected into the arm or leg. It stimulates（刺激）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.Patients in the early stages of the disease recovered more quickly in the trial.A:RightB:WrongC:Not mentioned
Many forms of cancer can be cured if detected early.A:selectedB: operatedC: developedD: discovered

Skin cancer is by far the most common form of cancer.

Sunburn,of course,is the initial hazard posed by UV radiation.Prolonged exposure to UV,howev-er , interferes with the production of collagen fibers（胶原纤维）in the dermis（真皮层）, causing the skin to lose elasticity（弹性）and creating premature wrinkles. Further deterioration（恶化）of the dermis deprives the epidermis（表皮层）of nutrition and causes it to become thin and dry.Cancer is UV's final result.Shortwave radiant energy,especially from the UV-B band,breaks the strands（股、缕）of DNA. Enzymes（酶）work constantly to rearrange the DNA into proper Se-quence,but with repeated UV exposure,the repair process may eventually break down.Then the mutant（变异的）DNA may produce a colony of cancer cells. But skin cancer may be avoided with a good dose of common sense.People with fair skin and blue eyes who burn easily stand the high-est risk .Special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks , nose , lower lip and the ears. People who have already developed precancerous（癌变前的）lesions（伤害）or had one skin-cancer growth stand a greatly increased chance of developing others.Dermatologists（皮肤科医生）recommend avoiding the sun when it is most intense between 11 a.m.and 3 p.m.Anyone who insists on sunbathing should use a good sun screen.These lotions and salves（药膏）contain chemicals that block out the burning UVB radiation while permitting the tanning rays to reach the skin.

共用题干第二篇 New U. S. Plan for Disease PreventionUrging Americans to take responsibility for their health,Health and Human Services Secretary Tommy Thompson on Tuesday launched a $15 million program to try to encourage communities to do more to prevent chronic diseases like heart disease,cancer and diabetes（糖尿病）.The initiative highlights the costs of chronic diseases一the leading causes of death in the United States一and outlines ways that people can prevent them,including better diet and increased exercise."In the United States today,7 of 10 deaths and the vast majority of serious illness, disability and health care costs are caused by chronic diseases,"the Health and Human Services department said in a statement.The causes are often behavioral一smoking,poor eating habits and a lack of exercise."I am convinced that preventing disease by promoting better health is a smart policy choice for our future,"Thompson told a conference held to launch the initiative."Our current health care system is not structured to deal with the rising costs of treating diseases that are largely preventable through changes in our lifestyle choices."Thompson said heart disease and strokes will cost the country more than $351 billion in 2003."These leading causes of death for men and women are largely preventable,yet we as a nation are not taking the steps necessary for us to lead healthier,longer lives,"he said.The $15 million is designed to go to communities to promote prevention,pushing for changes as simple as building sidewalks to encourage people to walk more.Daily exercise such as walking can prevent and even reverse heart disease and diabetes,and prevent cancer and strokes.The money will also go to community organizations,clinics and nutritionists who are being encouraged to work together to educate people at risk of diabetes about what they can do to prevent it and encourage more cancer screening.The American Cancer Society estimates that half of all cancers can be caught by screening, including Pap tests（巴 氏实验）for cervical（子宫颈的）cancer, mammograms（乳房X线照片）for breast cancer, colonoscopies（结肠镜检查）,and prostate（前列腺的）checks.If such cancers were all caught by early screening,the group estimates that the survival rate for cancer would rise to 95 percent. Early cancer screening can help reduce significantlyA:the death rates for all chronic diseases.B: the kinds of cancer attacking people.C:the incidence rate for cancer.D:the death rate for cancer.
