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.

资料：Up to 80 per cent of the world’s middle classes will live in developing countries by 2030 thanks to surprising recent gains in poverty reduction, according to a United Nations report published on Thursday.“Never in history have the living conditions and prospects of so many people changed so dramatically and so fast.” concludes the UN’s latest Development Report. “The world is witnessing an epochal ‘global rebalancing’.”Underpinning the improvements in the human development index（HDI） was rapid growth in countries such as China, India and Brazil, with China and India having doubled per capita economic output in less than 20 years. But the study stressed that growth and improvements in HDI spread far beyond the four Bric countries of Brazil, Russia, India and China, and included at least 40 countries that had accompanied greater economic dynamism with effective poverty-reduction policies.Afghanistan, Sierra Leone, Ethiopia, Rwanda and Angola were among 14 countries that have recorded gains in HDI of more than 2 per cent a year since 2000. Partly as a result, the report found that worldwide extreme income poverty has plunged from 43 per cent in 1990 to just 22 per cent in 2008, including more than 500m being lifted out of poverty in China alone. The report stated that such gains had already helped the world achieve the main poverty eradication goal of the so-called Millennium Development Goals, which called for the share of people living on less than $1.25 a day to be cut by half from 1990 to 2015.Underpinning this poverty reduction was developing countries’ increasing share of global trade, which grew from 25 per cent to 47 per cent between 1980 and 2010. “The south as a whole is driving global economic growth and societal change for the first time in centuries,” says the report.The report found that trade among developing countries was the biggest factor in that expansion, increasing from less than 10 per cent of total global trade to more than 30 per cent. “Trade between countries in the south will overtake that between developed nations,” the report said.Why does the author mention “an epochal ‘global rebalancing’”？A.To explain the recent achievement of poverty reductionB.To conclude that the world has changed so dramaticallyC.To criticize developed countriesD.To predict that things can be better
共用题干More,Rural Research Is Needed 1 Agricultural 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 technologies and the development of new ones,the world should be able to stay ahead. 2 "The global decline in investment in international agricultural research must be rwersed if significant progress is to be made towards reducing malnutrition and poverty,"he said. 3 Research is needed to solve food production,land degradation 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一East Asia. 4 The developing world was investing about 0.5%,or $8 billion a year,of its agricultural gross domestic product(GDP)on research,and the developed world was spending 2.5%of its GDP.Dr.Fischer said more was needed from all countries. 5 He said crop research could produce technologies that spread across many countries,such as wheat roduction research having spin-offs for Mexico,China or India. 6 "Technologies still need to be refined for the local conditions but a lot of the strategic research can ave global application,so that money can be used very efficiently,"Dr.Fischer said. 7 Yields of rice,wheat and maize have grown impressively in the past 30 years,especially in developing countries.For example,maize production rose from 2-8 tonnes per hectare between 1950 and 1995.But technologies driving this growth,such as high-yield varieties,fertilisers,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.Dr.Fischer claims that agriculture will continue to develop______.A:if we can drive yield upB:when Mexico,China and India join in the projectC:if we want to fight against malnutrition and povertyD:when we use modern technologies and develop new onesE:when the developed world helps the developing worldF:when strategic research can be utilized worldwide

问答题Practice 2 Today monocultures have increased dramatically worldwide, mainly through the geographical expansion of land devoted to single crops and year-to-year production of the same crop species on the same land. Available data indicate that the amount of crop diversity per unit of arable land has decreased and that croplands have shown a tendency toward concentration. There are political and economic forces influencing the trend to devote large areas to monoculture, and in fact such systems are rewarded by economies of scale and contribute significantly to the ability of national agricultures to serve international markets. The technologies allowing the shift toward monoculture were mechanization, the improvement of crop varieties, and the development of agrochemicals to fertilize crops and control weeds and pests. Government commodity policies these past several decades encouraged the acceptance and utilization of these technologies. As a result, farms today are fewer, larger, more specialized and more capital-intensive. At the regional level, increases in monoculture farming meant that the whole agricultural support infrastructure (i.e. research, extension, suppliers, storage, transport, markets, etc.) has become more specialized.
