Question

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 come up with an idea to convert banana peels to biogas.(生物氣).

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(糞), a commonly 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.

1.Why could Prithwis's finding receive the attention of the media?

A．Because he is a prodigy.

B．Because he is of Bengali descent.

C．Because he used an extremely rare organic waste to produce biogas.

D．Because his research proved that banana peels can produce more biogas.

2.Where did Prithwis derive his inspiration  from?

A.Lake Junior High.   B Discovery Channel.

C.  India.            D.His laboratory at home.

3.This article probably appeared in a _________ magazine.

A．gourmet          B．science           C．computer         D．fashion

 

Answer 1

【答案】

 

1.D

2.C

3.B

【解析】

試題分析：本文講述了一種新型的生產(chǎn)出生物氣的物質(zhì)—香蕉片。文章里解釋了這一現(xiàn)象的原理與發(fā)現(xiàn)過(guò)程。

1.D 細(xì)節(jié)題。根據(jù)文章第二段This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has come up with an idea to convert banana peels to biogas.(生物氣).可知D項(xiàng)內(nèi)容正確，香蕉片可以產(chǎn)生更多的生物氣。故D正確。

2.C 細(xì)節(jié)題。根據(jù)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.可知他是從印度，有了這樣的想法的。故Ｃ正確。

3.B 推理題。本文講述的是用香蕉片生產(chǎn)出更多的生物氣，這屬于生物科技方面的內(nèi)容，故B正確。

考點(diǎn)：考察科學(xué)知識(shí)類短文閱讀

點(diǎn)評(píng)：本文講述了一種新型的生產(chǎn)出生物氣的物質(zhì)—香蕉片。文章里解釋了這一現(xiàn)象的原理與發(fā)現(xiàn)過(guò)程。文章基本上是考查細(xì)節(jié)題，對(duì)此類題型考生可以首先從問(wèn)題中找到關(guān)鍵詞，然后以此為線索，運(yùn)用略讀及查閱的技巧在文中迅速尋找這一細(xì)節(jié)，找到后再把這一部分內(nèi)容仔細(xì)閱讀一遍，仔細(xì)比較所給選項(xiàng)與文中細(xì)節(jié)的細(xì)微區(qū)別，在準(zhǔn)確理解細(xì)節(jié)的前提下，最后確定最佳答案。
