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

Yesterday my friends or I visited a model high school. We start our visit from the main
building. First we went to the lab building in that some students were doing experiments. Then we entered in the lecture hall behind the lab building and saw many students listen to a lecture given a professor. Next to the lecture hall was the art center. There they watched groups of students playing musical instrument. On the playground some boys were playing the football. It was so exciting that we couldn’t help cheer for them. It was really an impressive visit.

---Miss Li, where did you visit last week?
--- I visited a big company __________ ships are made.

My father 　33　 a gene which，in most cases，results in blindness. I’d inherited the gene. He gradually 　34　 his eyesight and so did I. At last we were both 　35　 blind—he was fifty-seven years old，　36　 I was only twenty-eight.

My world 　37　 as the darkness fell，　38　 the dreams my husband and I had for us and for our three little boys. But 　39　 I tried to find some hope and 　40　，my eyes were opened to a new realization.

My father had 　41　 me not just failing eyesight，but an example of 　42　 in the face of hardships as well. We were all living in Bolivia in 1964 when he decided to 　43　 the family to America. He worked tirelessly to 　44 the right of living in the US.

Alone in the States，he 　45　 his helplessness and lack of fluency in English. He managed to rent a small apartment，and nine months later，sent airline tickets for my mom，my brother and me.

Decades later，　46 an American citizen，I look back at what he'd shown me. He set an example proving that determination is important to success. His 　47　 taught me valuable lessons for my own path in the darkness.
