- 共用题干 Lung CancerThe 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._________(46)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._________(47)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.Sometimes cases of lung cancer are discovered at the time an X-ray is taken for the purpose of detecting tuberculosis._________(48)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._________(49)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 in-fected,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 re-move 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._________(50)A: A common form of lung cancer is bronchogenic carcinoma,so-called because the malig-nancy 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 ear-ly 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.

- 共用题干 Research Shows Walking Can Lift DepressionNew research by German scientists shows that author Charles Dickens was onto a good thing when he took long,brisk walks to relieve periodic bouts of depression.The author of Oliver Twist and David Copperfield would walk for hours in the l860s as an antidote to intense feelings of sadness which alternated with restless euphoria.__________(46)Aerobic exercise like rapid walking can be more effective at lifting depression than drugs,reported the scientists led by Dr. Fernando Dimeo._________(47)The team found that in 10 of these patients drugs had failed to bring any substantial improvement.The team devised an exercise regime for the group that involved walking on a treadmill for 30 minutes every day.__________(48)The intensity of the training programme was stepped up as the heart rate adapted.A measurement of depression severity was taken at the start and the end of the programme,and patients were asked to rate their own mood regularly over a 10-day period.The researchers in Berlin found that after 10 days of the course six patients felt"substantially less depressed". ___________(49)Two were slightly less depressed,while four others remained unchanged.Depression levels overall fell by a thirds and on the self-assessed scores by 25 percent,said the researchers whose findings appeared in the British Journal of Sports Medicine.The study was small but the extent of the improvement was said by scientists to be impressive._____(50)Nineteenth century doctors would have called Dickens'condition melancholia since the psychological condition of depression was unknown.Dickens'biographer Peter Ackroyd says the author's son Charles remembers his father's"heavy moods of deep depression"and many times of"intense nervous irritability", something modern psychologists would certainly recognize._________(47)A:The number included five people who had not found any relief using drug treatment.B:Long and brisk walks are not necessarily beneficial to every person.C:They studied 12 people with severe depression that had lasted an average of nine months.D:The outcome indicated a clinical benefit which could not be obtained with pharmacological treatment currently available,they said.E:This is also the advice that experts from the Free University in Berlin are giving today.F:According to the regime,intense activity lasting three minutes was alternated with walking at half speed for three minutes.

- 共用题干 Organ Donation and Transplantation1 Organ donation（捐献）and transplantation（移植）refers to the process by which organs or tissuesfrom one person are put into another person's body.2 The number of people needing a transplant continues to rise faster than the number of donors.About 3,700 transplant candidates are added to the national waiting list each month.Each day,about 77 people receive organ transplants.However,18 people die each day waiting for transplants that can't take place because of the shortage of donated organs.3 There are rio age limits on who can donate.Newborns as well as senior citizens have been organ donors. If you are under age 18 , you must have a parent's or guardian's consent（同意）.If you are 18 years or older,you can show you want to be an organ and tissue donor by signing a donor card.4 Many people think that if they agree to donate their organs,the doctor or the emergency room staff won't work as hard to save their life.This is not true.The transplant team is completely separate from the medical staff working to save your life.The transplant team does not become involved with you until doctors have determined that all possible efforts to save your life have failed.5 If you need an organ transplant,your doctor will help you get on the national waiting list.Your name will be added to a pool of names.When an organ donor becomes available,all the patients in the pool are compared to that donor. Factors such as blood and tissue type, size of the organ, medical urgency（紧急）of the patient's illness , time already spent on the waiting list, and distance between donor and recipient（接受 者）are considered.Paragraph 3_________A: Quality of Donated OrgansB: Benefits of Organ DonationC:Distribution of Donated OrgansD:Quality of Donor Medical CareE:Age Limits for Organ DonationF:Status of Organ Donation and Transplantation
