20.Seth DeBolt is a plant scientist at the University of Kentucky.He and other scientists want to find:a source of fuel that the poor people in rural areas of developing countries could use,to supply themselves with electricity.Professor DeBolt went on a study trip:to rural areas in Indonesia.He saw that,everywhere he went,there was little waste in the use of agricultural products.Everything that farmers grew was used for something; Even the remains of fruit that people did not eat were fed to chickens.
Little waste meant there was little that could be used for fuel.Growing fuel crops would take land away from food crops,That was something Professor DeBolt did not want.to do.But he found some items that were in plentiful supply and:l would not cause the competition between food and fuel.Coconut shells:(椰壳) are generally thrown out.Yet Professor DeBolt says there is a Lot of energy stored in them.He says they have an excellent heating,value which can be compared to coal.All someone needs is a way to release that energy.
A company in India is using small generators(发电机) in Villages to make electricity from remains of rice.The process used is called gasification(气化).Heating plant matter in a low-oxygen condition releases gases.These can be burned in an engine that powers a generator.Professor DeBolt says he and his team see possibilities of coconut power.
The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia.Other tropical countries with large crops of coconuts and similar fruit could benefit as well.But Professor DeBolt says this is not a perfect solution There are technical rubs,like how to safely deal with the.dangerous waste that gasification can produce And it needs much money to make these projects start.

分析 本文讲述了科学家要在农村找到一种可以发电的植物且不占用农田.随后发现椰子树就是这样一种植物.但椰子树也有它的缺点.
解答 56题答案:They want to find a certain source of fuel to make electricity
解析:根据文章第一段的He and other scientists want to find:a source of fuel that the poor people in rural areas of developing countries could use,to supply themselves with electricity.(他和其他的科学家想找到:一种在发展中国家的贫困人民可以使用的燃料资源为他们自己供电)及题目要求可知本题答案为:They want to find a certain source of fuel to make electricity.
57题答案:Because growing fuel crops would take land away from food crops
解析:根据文章第三段的Growing fuel crops would take land away from food crops,That was something Professor DeBolt did not want.(种植燃料作物会剥夺食物作物的土地--这正是DeBolt教授不想要的)及题目要求可知本题答案为:Because growing fuel crops would take land away from food crops
58题答案:Questions/Problems/Difficulties
解析:根据后面的…like how to safely deal with the dangerous waste (比如说如何安全地处理危险的废弃物)可知划线部分单词意为"问题",故结合题目要求可知本题答案为:Questions/Problems/Difficulties.
59题答案:Because there is a lot of energy stored in them
解析:根据文章第三段的Yet Professor DeBolt says there is a Lot of energy stored in them.(然而DeBolt教授说在椰子壳中含有大量的能量)及题目要求可知,本题答案为:Because there is a lot of energy stored in them.
60题答案:It is not a perfect solution,because there are technical rubs and it needs much money to make these projects start
解析:根据文章最后一段的But Professor DeBolt says this is not a perfect solution There are technical rubs,like how to safely deal with the dangerous waste that gasification can produce And it needs much money to make these projects start.(但是DeBolt教授说这不是一个完美的解决办法:有很多的问题,比如如何处理气化过程中可能产生的危险废弃物及其需要大量的钱来启动这些项目)及题目要求可知,本题答案为:It is not a perfect solution,because there are technical rubs and it needs much money to make these projects start.
