More Rural Research is Needed
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 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.

参考答案
参考解析
解析：主旨大意题。首段提到如果世界人民想要吃的更好，农业研究基金的投入至关重要。也就是说，农业研究至关重要。接下来几段也都是在讲述农业研究对粮食生产等方面的重要性。因此本文主旨是农业研究的重要性。故本题选C。
根据第二段“The global decline in investment in international agricultural research must be reversed if…”可知，世界农业研究资金的投入都在下降。故选B。
文章第三段“The major improvement will be in East Asia…”提到，主要改善地区将是东亚等地。也就是说，在第一个25年，东亚的饥俄人口将会减少。故本题选D。
根据文章倒数第二段“Technologies still need to be refined for the local conditions. ”可知，技术仍然需要因地制宜进行改进。故本题选B。
根据最后一段费舍博士的话可以推断，人类需要腾出土地作为非农业用途。选项 B在最后一段已经明确提出，C、D项是无中生有。因此本题选A。
根据第二段“The global decline in investment in international agricultural research must be reversed if…”可知，世界农业研究资金的投入都在下降。故选B。

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 reduction
B.To conclude that the world has changed so dramatically
C.To criticize developed countries
D.To predict that things can be better

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

Deaths Associated with Sugary Soft DrinksSugar-sweetened sodas,sports drinks and fruit drinks may be associated with about 180,000 deaths around the world each year,according to a recent research.Sugar-sweetened beverages are consumed throughout the world,and contribute to excess body weight,which increases the risk of developing diabetes,cardiovascular diseases and some cancers. Using data collected as part of the 2010 Global Burden of Diseases Study,the researchers linked intake of sugar-sweetened beverages to 133,,000 diabetes deaths,44,000 deaths from cardiovascular diseases and 6,000 cancer deaths.Seventy-eight percent of these deaths due to over-consuming sugary drinks were in low and middle-income countries,rather than high-income countries."In the U.S.,our research shows that about 25,000 deaths in 2010 were linked to drinking sugar-sweetened beverages,"said Mr. Singh,a postdoctoral research fellow at the Harvard School of Public Health in Boston.Of nine world regions,Latin America/Caribbean had the most diabetes deaths(38,000)related to the consumption of sugar-sweetened beverages in 2010.Japan,one of the countries with lowest per-capita consumption of sugary beverages in the world,had the lowest death rate associated with the consumption of sugary beverages,at about 10 deaths due to per million adults."Because we were focused on deaths due to chronic diseases,our study focused on adults.Future research should assess the amount of sugary beverage consumption in children across the world and how this affects their current and future health,"Singh said.The American Heart Association recommends adults consume no more than 450 calories per week,from sugar-sweetened beverages,based on a 2,000 calorie diet and offers tips to help you make better lifestyle choices and eat healthier.Korea had the lowest death rate associated with the consumption of sugary beverages.A:Right B:Wrong C:Not mentioned

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.
