【题目】【2016广东广州】 阅读下列短文，从26-45各题所给的A.B.C.和D项中选出最佳的选择，并在答题卡上将该选项涂黑.

Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America. However, things went from bad to worse in March 2015 after heavy rains damaged the only power cables in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.

Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

While that may sound amazing and even impossible, the science behind the ides is quite simple. As plants create their food (using the sun’s energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons – the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp’s batteries for later use. The researchers say a single charge can power a 50-watt Led light for two hours - enough time for local villagers to get their evening work done.

The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2015. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

【解析】

试题分析：本文是篇说明文，介绍了一项新发明。它能够让没有供电的雨林地区的人们利用丰富的植物资源制造一种新的“植物电灯”。

【小题1】D细节理解题。根据The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.可知，油灯不仅贵还会产生有害气体。故选D。

【小题2】B细节理解题。根据Tiny animals in the soil eat this waste and they produce electrons土壤里面的微生物吃掉了植物产生的废物并生成了电子，因此这种植物灯所产生的电来源于植物所产生的废物。故选B。

【小题3】D细节理解题。根据They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies.可知，植物灯生电的材料主要是植物，而植物在雨林地区很容易找到。故选D。

【小题4】A细节理解题。根据从全文最后一句可知该植物灯更多是用于那些没有供电的地区，如热带雨林。故选A。

【小题5】A写作意图题。根据本文主要介绍了一项新发明—植物灯。故选A。
