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

共用题干第一篇Why So Many ChildrenIn many of the developing countries in Africa and Asia,the population is growing fast.The reason for this is simple.Women in these countries have a high birth rate一from 3.0 to 7.0 children per woman.The majority of these women are poor,without the food or resources to care for their families.Why do they have so many children?Why don't they limit the size of their families?There are several reasons for this.One reason is economic.In a traditional agricultural economy,large families are helpful.Having more children means having more workers in the fields and someone to take care of the parents in old age.In an industrial economy,the situation is different.Many children do not help a family;instead,they are an ex- pense.Thus,industrialization has generally brought down the birth rate.This was the case in Italy,which was industrialized quite recently and rapidly.In the early part of the twentieth century,Italy was a poor,largely agricultural country with a high birth rate.After World War II,Italy's economy was rapidly modernized and industrialized. By the end of the century,the birth rate had dropped to 1.3 children per woman,the world's lowest.However,the economy is not the only important factor that influences birth rate.Saudi Arabia,for exam- pie,does not have an agriculture-based economy,and it has one of the highest per capita incomes in the world.Nevertheless,it also has a very high birth rate(7.0).Mexico and Indonesia,on the other hand,are poor countries,with largely agricultural economies,but they have recently reduced their population growth.Clearly,other factors are involved.The most important of these is the condition of women.A high birth rate almost always goes together with lack of education and low status for women.This would explain the high birth rate of Saudi Arabia.There,the traditional culture gives women little education or independence and few possibilities outside the home.On the other hand,the improved condition of women in Mexico,Thailand,and indonesia explains the decline in birth rates in these countries.Their governments have taken measures to provide more education and opportunities for women.Another key factor in the birth rate is birth control.Women may want to limit their families but have no way to do so.In countries where governments have made birth control easily available and inexpensive,birth rates have gone down.This is the case in Singapore,Sri Lanka,and India,as well as in Indonesia,Thailand, Mexico,and Brazil.In these countries,women have also been provided with health care and help in planning their families.These trends show that an effective program to reduce population growth does not have to de- pend on better economic conditions.When countries become industrialized,_________.A:the birth rate generally goes downB:families often become largerC:women usually decide not to have a familyD:the population generally grows rapidly

共用题干第三篇Global Cancer Rates to Rise by 50% by 2020The number of new cancer cases worldwide is expected to increase by 50%by the year 2020.But a new report suggests that as many as a third of new cancers could be avoided by adopting healthier lifestyles and through public health action.The World Cancer Report,released by the International Agency for Research on Cancer,shows that cancer has now emerged as a major public health threat in developing countries as well as rich ones.Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries more than a quarter of all deaths are caused by cancer.The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that number is expected to rise to 15 million by 2020.Researchers say most of that increase will mainly be due to steadily aging populations in both developed and developing countries and current trends in smoking and other unhealthy habits."Cancer has emerged as a major public health problem in developing countries for the first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul Kleihues,MD,director of IARC,in a news release."Once considered a'Western' disease,the Report highlights that more than 50 percent of the world's cancer burden,in terms of both numbers of cases and deaths,already occurs in developing countries."The risk of being diagnosed with cancer in developed countries is double that in less-developed ones.However,the risk of dying from cancer is much higher in developing countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤） at the time of diagnosis.Researchers say cancer rates have traditionally been higher in developed countries due to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy Western diet and lifestyle.As less-developed countries become industrialized and more prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen in the West,which increase cancer rates. The report says that steps could be taken to reduce aboutA:50% of new cancers. B:33% of new cancers.C:12% of new cancers. D:80% of new cancers.

单选题Passage1 In many of the developing countries in Africaand Asia, the population is growing fast. The reason for this is simple: Womenin these countries have a high birth rate - from 3.0 to 7.0 children per woman.The majority of these women are poor, without the food or resources to care fortheir families. Why do they have so many children? Why don't they limit thesize of their families? The answer may be that they often have no choice. Thereare several reasons for this. Onereason is economiIn atraditional agricultural economy, large families are helpful. Having morechildren means having more workers in the fields and someone to take care ofthe parents in old age. In an industrial economy, the situation is different.Many children, do not help a family; instead, they are an expense. Thus,industrialization has generally brought down the birth rate. This was the casein Italy, which was industrialized quite recently and rapidly. In the earlypart of the twentieth century, Italy was a poor, largely agricultural countrywith a high birth rate. After World WarⅡ, Italy's economy was rapidly modernized and industrializeBy theend of the century, the birth rate had dropped to 1. 3 children per woman, theworld's lowest.However,the economy is not the only important factor that influences birth rate. SaudiArabia, for example, does not have an agriculture-based economy, and it has oneof the highest per capita incomes in the worlNevertheless,it also has a very high birth rate. Mexico and Indonesia, on the other hand,are poor countries, with largely agricultural economies, but they have recentlyreduced their population growth. Clearly,other factors are involveThemost important of these is the condition of women. A high birth rate almostalways goes together with lack of education and low status for women. Thiswould explain the high birth rate of Saudi Arabia. There, the traditionalculture gives women little education or independence and few possibilitiesoutside the home. On the other hand, the improved condition of women in Mexico,Thailand, and Indonesia explains the decline in birth rates in these countries.Their governments have taken measures to provide more education andopportunities for women. Anotherkey factor in the birth rate is birth control. Women may want to limit theirfamilies but have no way to do so. In countries where governments have madebirth control easily available and inexpensive, birth rates have gone down.This is the case in Singapore, Sri Lanka, and India, as well as in Indonesia,Thailand, Mexico, and Brazil. In these countries, women have also been providedwith health care and help in planning their families. Thesetrends show that an effective program to reduce population growth does not haveto depend on better economic conditions.3 It can be effective if it aims tohelp women and meet their needs. Only then, in fact, does it have any realchance of success. (495 words) In a traditional agricultural economy, a large family_______.Acan be an advantageBmay limit incomeCisn't necessaryDis expensive
