[不定项选择题]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 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. The more cigarettes one smokes,______.
A.before the cancer cells spread elsewhere
B.the more chances of dying of X-ray radiation he will have
C.what is most responsible for lung cancer
D.as some people imagine
E.the more chances of getting lung cancer he will have
F.which form of lung cancer is a common one

[单项选择]

Education begins with teachers. Yet teaching seems to be losing its appeal for many of the best and brightest college students. In high school, many of the best students decide that they want to be teachers, but their relatives and friends soon convince them to change their minds. One student’s mother kept reminding her of the relatively skimpy salaries teachers currently earn until the student changed to another major. Another student took computer science courses because his father thought that teachers were at the bottom of the social ladder. One said that none of her friends looked upon teaching as a worthwhile career, so she came to think of teaching as not noble enough and went into pharmacy instead. According to several recent reports on the shortcomings of American public schooling, teaching’s lack of appeal for the brightest college students is one of the teaching profession’s most worr
