Question

A few degrees can make a big difference when it comes to food storage. Foods can go bad if they get too warm. But for many of the world’s poor, finding a good way to keep food cool is difficult. Refrigerators are costly and they need electricity.

   Yet spoiled food not only creates health risks but also economic losses. Farmers lose money when they have to throw away products that they cannot sell quickly.

    But in nineteen ninety-five a teacher in northern Nigeria named Mohammed Bah Abba found a solution. He developed the “Pot-in-Pot Preservation/Cooling System.” It uses two round containers made of clay. A smaller pot is placed inside a larger one. The space between the two pots is filled with wet sand. The inner pot can be filled with fruit, vegetables or drinks. A wet cloth covers the whole cooling system.

    Food stored in the smaller pot is kept from spoiling through a simple evaporation(蒸發(fā)) process. Water in the sand between the two pots evaporates through the surface of the larger pot, where drier outside air is moving.

    The evaporation process creates a drop in temperature of several degrees. This cools the inner pot and helps keep food safe from harmful bacteria. Some foods can be kept fresh this way for several weeks.

    People throughout Nigeria began using the invention. And it became popular with farmers in other African countries. Mohammed Bah Abba personally financed the first five thousand pot-in-pot systems for his own community and five villages nearby.

    In two thousand, the Rolex Watch Company of Switzerland honored him with the Rolex Award for Enterprise. This award recognizes people trying to develop projects aimed at improving human knowledge and well-being. A committee considers projects in science and medicine, technology, exploration and discovery, the environment and cultural history. Winners receive financial assistance to help develop and extend their projects.

5.C

【解析】

試題分析：文章介紹了穆罕默德巴林神父發(fā)明的“罐內(nèi)冷卻系統(tǒng)”的儲藏食物的方法。他利用兩個套在一起的罐子中間的濕沙子蒸發(fā)水分降溫的原理來保存食物。這一發(fā)明還獲得了瑞士的勞力士公司授予他的“勞力士雄才偉略大獎”。

1.主旨題，通過閱讀全文可知本文介紹了一種降溫方法來防止食物腐壞。故選B。

2.推理題，閱讀第三段可知介紹了這種發(fā)明的組成和原理。故選A。

3.推理題。根據(jù)第五段中“The evaporation process creates a drop in temperature of several degrees.”蒸發(fā)的過程會產(chǎn)生幾度的溫度下降，根據(jù)常理可知降低了溫度會使食物保鮮。故選D。

4.推理題，閱讀文章可知這個發(fā)明最初是在尼日利亞北部的人們使用，后整個尼日利亞人們都是用，再后來還在其他非洲國家的農(nóng)民中流行起來，由此可知是在不發(fā)達地區(qū)和窮人中運用。故選C。

5.推理題，根據(jù)文章最后一句“ Winners receive financial assistance to help develop and extend their projects.”獲獎?wù)邥�獲得財務(wù)援助以幫助開發(fā)和擴大他們的項目。根據(jù)文章可知穆罕默德巴林神父也獲得這個獎項，因此可知穆罕默德巴林神父獲得對他的發(fā)明的財務(wù)支持。故選C。
