How could we have thought so wrongly of as banana peel that it always hits the garbage? Utility of anything seems to be in the eyes of the beholder. The banana peel hasn't been an exception.
What most of us looked at as waste was converted to a thing of utility by Prithwis Mukhopadlyay, a 14-year-old prodigy. This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has e up with an idea to convert banana peels to biogas.(生物气).
It's well known that almost any organic waste can be converted to biogas. But why biogas from banana peel has hit the news is because it produced five times as much biogas as manure(粪), a monly used source for producing biogas, in the experiments Prithwis conducted.
He filled two airtight containers, one with manure and the other with banana peels. Then he mixed each content with water and connected them to empty jars via pipes to collect the gas produced. He placed a heater next to each jar and measured the gas collected for 60 days. His studies proved that banana peels produced five times more biogas than manure.
This project titled 'Comparison analysis: Eco-friendly source of energy for the future,' earned him a spot in Discovery Channel Young Scientist Challenge. This weekend, the young whiz is to showcase his research work along with 40 other finalists at Washington. Initially, I thought of doing a project that would reduce global warming. Things changed after I visited a biogas plant in a village in India during my summer vacations. It was an amazing experience, Prithwis says.

网友回答
(答案→)D
解析：本文讲述了一种新型的生产出生物气的物质—香蕉片。文章里解释了这一现象的原理与发现过程。
【小题1】D 细节题。根据文章第二段This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has e up with an idea to convert banana peels to biogas.(生物气).可知D项内容正确，香蕉片可以产生更多的生物气。故D正确。
【小题2】C 细节题。根据文章最后2行Things changed after I visited a biogas plant in a village in India during my summer vacations. It was an amazing experience, Prithwis says.可知他是从印度，有了这样的想法的。故Ｃ正确。
【小题3】B 推理题。本文讲述的是用香蕉片生产出更多的生物气，这属于生物科技方面的内容，故B正确。
