The principal factor depressing life expectancy in developing countries has always been the high death rate for infants and children. The World Bank studies suggest that as much as two thirds of the difference in life-spans between people in developed countries and those in developing ones can be traced to differences in survival rates for children under five. It is here where the most improvement has come. According to UN estimates, significant regional drops in infant mortality - ranging from 25 percent to 60 percent and centering near 40 percent - appear to have taken place between the late 1950s and the late 1970s in northern Africa, Latin America, and Asia. Although sub-Saharan Africa' s mortality trends cannot be quantified with confidence, there is reason to believe that life expectancy has risen and infant mortality has declined in that region as well. There is little doubt that population growth has accelerated in sub-Saharan Africa since the 1950s; in fact, sub-Saharan Africa is widely thought to have the highest rate of population growth of any major region in the world. Only a small portion of that acceleration is likely to have been caused by increases in fertility (and increases in fertility, insofar as they have occurred, may also imply improvements in health and nutrition).Mortality, of course, is not a perfect measure of nutritional change. Improved nutrition is only one of a number of forces that have been pushing down death rates in developing countries. Others include the upgrading of hygiene and sanitation; the extension of public health services; medical innovations; improvements in education, communications, transportation, and, in some areas, civil order. Even so, the extent to which improvements innutrition—both direct and indirect—have reduced mortality in developing countries has frequently been underestimated. For example, Sri Lanka experienced an abrupt jump in life expectancy shortly after the Second World War. Whereas this was long described as a "technical fix"—a triumph of DDT over the anopheles mosquito—years later researchers realized that abrupt and rapid drops in mortality had also taken place in Sri Lanka' s highlands, or "dry zones", where malaria had never been a serious problem. In both highlands and lowland regions health improved in tandem with access to food.According to the author, life expectancy in developing countries is not high mainly because developing countries______.A．have a low standard of livingB．have no public health servicesC．have no public and private hygiene and sanitationD．have low survival rates for infants and children
考题
The author holds that______.A．mortality rates in developing countries have been brought down by a number of forcesB．medical innovations are the only way to reduce mortality rates in developing countriesC．the upgrading of hygiene and sanitation has played a crucial role in reducing mortality rates in developing countriesD．improved nutrition is the only one factor that reduces mortality rates in developing countries

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.Paragraph 3______A:Common Secondary Lung CancersB:The Advantages 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 Causes F:An Ordinary Type of Lung Cancer

Being fat doesn’t necessarily mean you're unhealthy,according to a new study.Researchers at York University in Toronto found that obesity 1 doesnt increase your risk for mortality 2 it's 3 another metabolic risk factor,such as high blood sugar or high levels of bad cholesterol This is 4 most of the literature,Jennifer Kuk,a（n）5 professor of kinesiology at York University,writes in a press 6.She says 7,most studies defined"healthy"obesity 8 having up to one metabolic risk factor--which is an issue,9 conditions like high blood sugar and bad cholesterol increase mortality risk for anyone,skinny or fat.This is likely 10 most studies have reported that healthy'obesity is still 11 higher mortality risk,she says.The study looked at data of 54,089 men and women from five large studies,and 12 them into two groups:those who were obese and had no metabolic risk factors,and those who were obese and had metabolic 13 such as elevated glucose,blood pressure or lipids Researchers then looked at how many people in each group died,and 14 their numbers to the death rate for 15-weight folks who had no metabolic risk factors We found that a person of normal weight 16 no other metabolic nsk factors is Just as likely to die as the person with obesity and no other risk factors,"Kuk says.according to their 17 individuals with metabolically healthy obesity are actually not at an elevated mortality 18 This means that hundreds of thousands of people in North America with metabolically healthy obe sity will be told to lose weight when it's 19 how much benefit they'll actually 20 she concludes
