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More Rural Research is NeededAgricultural research funding is vital if the world is to feed itself better than it does now. Dr. Tony Fischer,crop scientist,said demand was growing at 2 .5%per year but with modern tech-nologies and the development of new ones,the world should be able to stay ahead.“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition（营养不良）and poverty.” he said.Research is needed to solve food production,land degradation（贫瘠化）and environmental problems. Secure local food supplies led to economic growth which in turn,slowed population growth .Dr. Fischer painted a picture of the world's ability to feed itself in the first 25 years, when the world's population is expected to rise from 5 .8 to 8 billion people.He said that things will probably hold or improve but there'll still be a lot of hungry people.The biggest concentration of poor and hungry people would be in sub-Saharan Africa and southern Asia in 2020,similar to the current pattern. if there is any change,a slight improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia,South America and South-East Asia.The developing world was investing about 0 .5%,or$8 billion a year,of its agricultural gross domestic product(GDP)on research and developed world was spending 2 .5%of its GDP. Dr. Fischer said more was needed from all countries.He said crop research could produce technologies that spread across many countries,such as wheat production research having spin-offs（有用的副产品）for Mexico, China or India.“Technologies still need to be refined for the local conditions but a lot of the strategic re- search can have global application,so that money can be used very efficiently.”Dr. Fischer said.Yields of rice, wheat ad maize（玉米）have grown impressively in the past 30 years, espe- cially in developing countries.For example,maize production rose from 2 to 8 tones per hectare between 1950 and 1995.But technologies driving this growth such as high-yield varieties,fertiliz-ers,and irrigation,were becoming exhausted.“If you want to save the land for non-agricultural activities,for forests and wildlife,you're going to have to increase yield.”Dr. Fischer said. What is the picture of Asia's food supplies in the first 25 years?A: Food shortage will not be a problem.B: There will be more hungry people in southern Asia.C: Population growth will result in more hungry people.D: There will be fewer hungry people in East Asia.

In recent decades, there is a phenomenon which makes us give some attention, the so-called Southeast Asian "Tigers" have rivaled the western"lions" for stock cliches that make economic headlines. The myth of American economic hegemony over Asia in the imposing and patriarchal figure of Uncle Sam has provided frequent political grist( 有利 ) for Southeast Asian political leaders,particularlyMalaysia'sPrimeMinisterMahathir.Hehasattemptedtoforgean international reputation as a snarling tiger, but lately sounds more like a barnyard dog groaning at shadows. Without demeaning in any way the remarkable achievements of the newly developing economics of Malaysia, Thailand and Indonesia, these nations at times appear to be their own worst enemies. This is often exemplified by Dr. Mahathir, who rails at Western evil whenever an international or domestic crisis provides an opportunity. To be more specific, the recent devaluation of the Philippine and Thai currencies, and the subsequent pressure on the Malaysian currency has inspired Dr. Mahathir to launch an all-out attack on the West as the source of the problem. He even alleges that the United States has deliberately destabilized Southeast Asian economics in revenge for these nations, supporting the brutal military rule in Mahathir, an action which the United States seems to want inspected rather than rewarded. But by resorting to such scapegoat(替罪羊), instead of accepting even a bit responsibility, the Prime Minister may undermine the future success of the region and Malaysia in particular. Upon further questioning, Dr. Mahathir narrowed his attack to one wealthy individual, the well-known philanthropist (慈善家), Mr. George Soros, whose opposition to Myanmar's admission to ASEAN(Association of Southeast Asian Nations) Mahathir found particularity, irritating. The logical mistakes that underlie such conspiracy theories do not help Malaysia address the serious issues of economic overheating that experts have been warning about for all these difficult periods,which include large deficits and low savings to debt ratios. In fact, the recent dramatic drop in Malaysia's stock market and currency has led Dr. Mahathir to reverse his initial approach to the crisis. He even announces measures that at least imply he is quite aware of excesses in his own administration's spending policies that have contributed to this crisis of confidence. In the end, this kind of reaction undermines the esteem that Dr. Mahathir's enlightened leadership has justly earned. The author of this essay seems to suggest that （ ）.A.the Asian Crisis is the result of ASEAN pandering to terrorist governmentsB.there is not a serious economic problem in Southeast Asia at allC.the devaluation of Malaysia's currency is due to the American plotD.the economic problems in some Asian countries is partly the result of their overheating economy
