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?

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.
【小题2】Where did Prithwis derive his inspiration  from?
A.Lake Junior High.   B Discovery Channel.
C.  India.            D.His laboratory at home.
【小题3】This article probably appeared in a _________ magazine.
A.gourmet B.science C.computer D.fashion


【小题1】D
【小题2】C
【小题3】B

Having returned from her round trip, the angry woman stood outside the ticket office of the station. “The railway owes me £12,” she said to Harry Jenks, the young man working at the office . “You sold me a ticket for May 22nd, but there was no ship from Jersey that night. So my daughter and I had to stay in a hotel. It cost me £12.”

       Harry was worried. He remembered selling the woman a return ticket. “Come into the office, Madam,” he said politely. “I’ll just check the Jersey timetable for May 22nd.”

       The woman and her little girl followed him inside. She was quite right, as Harry soon discovered. There was no sailing on May 22nd. How could he have made such a careless mistake? He shouldn’t have sold her a ticket for that day. Wondering what to do, he smiled at the child. “You look sun burnt,” he said to her. “Did you have a nice holiday in Jersey?”

       “Yes,” she answered, shyly. “The beach was lovely. And I can swim too!”

       “That’s fine,” said Harry. “My little girl can’t swim a bit yet .Of course, she’s only three…”

       “I’m four,” the child said proudly. “I’ll be four and a half.”

       Harry turned to the mother. “I remember your ticket, Madam,” he said. “But you didn’t get one for your daughter, did you?”

       “Er, well—” the woman looked at the child. “I mean… she hasn’t started school yet. She’s only four.”

       “A four-year-old child must have a ticket, Madam. A child’s return ticket to Jersey costs …let me see…£13.50. So if the railway pays your hotel, you will owe £1.50. The law is the law, but since the fault was mine…”

I   38   Salome Bey, telling her I was from Essence magazine, and that I wanted to meet her to talk her career. She   39   and told me to come to her studio next Tuesday.

I interviewed Salome Bey the next Tuesday.

It didn’t take long. My manuscript   45  . How stupid of me! I thought. How could I   46   in a world of professional writers? Knowing I couldn’t   47   the rejection letter, I threw the unopened envelope into a drawer.

Five years later, I was moving to California. While   48   my apartment, I came across the unopened envelope. This time I opened it and read the editor’s letter in   49  :

Dear Ms Profit,

Your story on Salome Bey is fantastic. Yet we need some   50   materials. Please add those and return the article immediately. We would like to   51   your story soon.

Shocked, it took me a long time to   52  . Fear of rejection cost me dearly. I lost at least five hundred dollars and having my article appear in a major magazine.

Peanuts to This

Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”

Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real talk I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.

Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quiet! How could I know that she meant that George Washington?

Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!

1.What did the author’s classmates think about his report?

A.Controversial.

B.Ridiculous.

C.Boring.

D.Puzzling.

2.Why was the author confused about the task?

A.He was unfamiliar with American history.

B.He followed the advice and flipped a coin.

C.He forgot his teacher’s instruction.

D.He was new at the school.

3.The underlined word “burning” in Para. 3 probably means _______.

A.annoyed

B.ashamed

C.ready

D.eager

4.In the end, the author turned things around _______.

A.by redoing his task

B.through his own efforts

C.with the help of his grandfather

D.under the guidance of his headmaster
