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

Nick was not the kind of boy I had expected to spend my summer with. I was hoping to have a relaxation the summer before my busy senior year, __36__ my mother asked me to do her a __37__. One of her colleagues needed a full-time __38__. “You planned to volunteer at the local hospital; why not volunteer to __39__ Nick instead?” Then she told me that this six-year-old boy was not a __40__ child.

Nick was a lovely little boy who suffered from many disorders. Normal day-care centers would not __41__ him. As a baby, he had serious ear infections which left him with equilibrium(平衡)problems. He couldn't __42__ or run properly. I was hesitating __43__ I was to take the job when my mother __44__, “Don't you want to be a nurse in the future? I doubt if you even have the __45__.”

Then I told her I was __46__ for the job.

The day started at 7:00 a.m. Nick was my wake-up call! With so much energy and very little __47__ , he was quite a mix.

At the park, when he saw all the other children play on the jungle gym and swings, the boy's face __48__ up—How he wished he belonged to the group of his age! You would think it would be__49__ to get a child to go down a slide. Believe me, it wasn't! It took time, a lot of time. But with patience and support, Nick took one step up the slide each day. We worked together to face his __50__ and gradually he got closer to taking the slide of his life.

Halfway through the summer, he __51__ it to the top of the slide. With my arms __52_ him tightly, we flew down the slide! I waited for his reaction. After realizing that he was safe and sound, he gave me a big __53__ and asked, “May I go down again, alone?”

I had never been happier in my life when I saw this little child climb the ladder and enjoy what other children __54__ for granted.

This __55__ child taught me that being a nurse means respect, kindness and patience.

Can you understand the beginning of this article?

“My smmr hols wr CWOT. B4, we usd 2go2 NY 2C my bro, his GF & 3 kds FTF.”

The Scottish teacher who received it in class had no idea what the girl who wrote it meant. The essay was written in a form of English used in cell phone text messages. Text messages (also called SMS2) through cell phones became very popular in the late 1990s. At first, mobile phone companies thought that text messaging would be a good way to send messages to customers, but customers quickly began to use the text messaging service to send messages to each other. Teenagers in particular enjoyed using text messaging, and they began to create a new language for messages called texting.

A text message is limited to 160 characters, including letters, spaces, and numbers, so messages must be kept short. In addition, typing on the small keypad of a cell phone is difficult, so it’s common to make words shorter. In texting, a single letter or number can represent a word, like “r” for “are,” “u” for “you,” and “2” for “to.” Several letters can also represent a phrase, like “lol” for “laughing out loud.” Another characteristic of texting is the leaving out of letters in a word, like spelling “please” as “pls.”

Some parents and teachers worry that texting will make children bad spellers and bad writers. The student who wrote the essay at the top of this page said writing that way was more comfortable for her. (The essay said, “My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three kids face to face.”)

Not everyone agrees that texting is a bad thing. Some experts say languages always evolve, and this is just another way for English to change. Other people believe texting will disappear soon. New technology for voice messages may soon make text messages a thing of the past.
