Question

【題目】 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(電力電纜) 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.

Answer 1

【答案】

【1】D

【2】B

【3】D

【4】A

【5】A

【解析】

本文介紹了一項新發(fā)明——“植物電燈”，它的發(fā)明者認(rèn)為這種燈能改善熱帶雨林國家的人們的生活，因為那里42%的社區(qū)沒有電。

【1】

細(xì)節(jié)理解題。根據(jù)第一段中“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，村民們被迫使用油燈，而油燈的問題是昂貴而且危險，因為它們會產(chǎn)生有害氣體，對健康有害。故選D。

【2】

細(xì)節(jié)理解題。根據(jù)第3段中“As plants …, 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.”可知，土壤里面的微生物吃掉了植物產(chǎn)生的廢物并生成了電子，電子是電能的組成部分，因此這種植物燈所產(chǎn)生的電來源于植物產(chǎn)生的廢物。故選B。

【3】

細(xì)節(jié)理解題。It can be made by local people.它可以由當(dāng)?shù)厝酥谱�。根�?jù)第二段中“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…”可知，植物電燈是由科技大學(xué)的研究人員制作的，當(dāng)?shù)厝瞬粫�制作，所�?/span>A項錯誤；It is much easier to use than oil lamps.它比油燈更容易使用。根據(jù)第三段中“The UT team put special sticks inside the soil to capture the energy and keep it in the lamp’s batteries for later use.”可知，紐約大學(xué)的研究小組在土壤中放置了特殊的樹枝來獲取能量，并將其保存在燈的電池中以備日后使用，過程比較繁瑣，而油燈只需要點燃就可以使用，所以植物電燈不如油燈更容易使用，所以B項錯誤；It can produce all the electricity the village need.它可以提供村子所需的所有電力。根據(jù)第三段中“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.”可知，研究人員說，一次充電可以為一盞50瓦的燈提供兩個小時的電力，足夠當(dāng)?shù)卮迕裢瓿赏砩系墓ぷ�，但并沒有提及可以提供村子里所需的所有電力，所以C項錯誤；The things it needs to make electricity are easy to find.它發(fā)電所需的東西很容易找到。根據(jù)第三段中“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，植物燈生電的材料主要是植物和土壤，而這些東西在雨林地區(qū)很容易找到，所以D項正確。故選D。

【4】

細(xì)節(jié)理解題。根據(jù)最后一段中“…believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities…”可知，植物電燈可以改善許多人們的生活，特別是一些熱帶雨林地區(qū)可以從中受益。故選A。

【5】

主旨大意題。根據(jù)文意可知，這篇短文中給我們介紹的是利馬科技大學(xué)的研究人員們發(fā)明的一種可以用植物和土壤提供的能量來照明的燈，解決了一個村莊的用電問題，所以這篇文章的目的是為了報道這項新發(fā)明。故選A。
