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.
选项
Paragraph 1______A:The Same or Improved Food Supply Situation in 2020B:Research Focuses on Increased YieldC:More Research Funding NeededD:Local Situations AnalyzedE:Increase in Investment on Agricultural ResearchF:Sustained Development of Modern Technologies
答案
E
解析
文章第一段第二句话中说“粮食需求每年增长2.5%”,且本段第一句话说“如果世界人民想比现在吃得更好,农业研究资金的投入就至关重要”。因此本段主要讲的是在农业研究方面要增加投资。故选E。 本段引用了Fischer博士的观点。他向我们描绘了2020年时世界的食物供应状况。到2020年,粮食供应很可能保持现状或有所改善,但仍然会有大批人口处于饥饿当中。故选A0 文章第四段第一句话说“发展中国家和发达国家投人了一部分资金进行农业研究”;最后一句话说“所有国家都需要投人更多的资金”。因此本段主要讲的是还需要投人更多的资金进行农业研究。故选C。 文章第七段第一句话说“在过去30年中,大米、小麦和玉米的产量大幅度增长”;第三句话说“但是,推进高产的技术正在消耗殆尽”;最后一句话提出了Fischer博士的观点“如果想要腾出土地将其用于非农业产业,我们就必须提高产量”。因此本段主要说的是对提高粮食产量的研究。故选B。 由文章第一段第二句话“…with modern technologies and the development of new ones , the world should be able to stay ahead.”可知,由于有了现代技术和新技术的开发,世界应该能够不断前进。故选D。 由文章第七段最后一句话“If you want to save the land for non-agricultural activities … you're going to have to increase yield.”可知,如果想要腾出土地将其用于非农业产业……就必须提高产量。故选A。 由文章第六段“…a lot of the strategic research can have global application , so that money can be used very efficiently.”可知,许多战术性研究可以在全球应用,这样就可以非常有效地利用资金。故选F。 由文章第二段“The global decline in investment in international agricultural research must be reversed…towards reducing malnutrition and poverty.”可知,要想在减少营养不良和贫困方面取得巨大进步,就必须扭转全球对国际农业研究投人下滑的趋势。故选C。
