This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu(棕榈) oil mixed with 80% conventional jet fuel.
What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions(排放)from airplanes. there are a lot of hurdles (障碍)that still need to be overcome.
First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet‘A’fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same.
The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter – the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up.
However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae(藻类)produced in sewage treatment plants, not from food sources.
Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project.
While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!

高三英语单项填空中等难度题查看答案及解析
In the middle of a hot July afternoon, I became a thief of some sort — a thief of music.
For the first time, I created an original piano arrangement of one of my favorite songs. Using only my ears and iPad, I transformed a mix of sounds and melodies into the tones of a single instrument; I created complex harmonies (和声) and voices into something I could perform with only two hands. No help, no guide — I did it on my own.
I've been a pianist since my hands grew big enough to touch the piano. With my father as a musician, I was all but born on the piano bench. For many years, my musical identity was defined by the notes that others had written in the past centuries: elegant lines of neatly printed notes stamped across the sheet music became the script I had to perform. I valued classical music — adored it — but I felt such performances were shallow. I had nothing of my own to contribute to the masterful compositions of Bach or Rachmaninov.
This was why, when I put the finishing touches to my piano version of a modem song, my pride was glorious: this arrangement was mine. What I'd done seemed magical: an ability to take what had already existed — to "steal" a song from my favorite band — and to change it into something different all on my own. I was a thief but I was also an artist.
In music, as in other aspects of life, I believe that true originality rarely exists. Almost everything has been done before, in one form or another. The most passionate romance novel may be a slightly changed version of a play written by Shakespeare, which in turn was borrowed from the writers of Ancient Greece: the same themes, different characters, and different circumstances. But the novel no less deserves praise just because its uniqueness is compromised.
The gift of creativity is just like the ability to do what I did on the piano: to find out something beautiful, to analyze and change it and lose yourself in the mystery of its composition, and then to make it new. Such an act is not copying; it is finding inspiration and having the strength and the innovation to use it as fuel for your own masterpiece.
1.Why did the author create the piano arrangement?
A.Because he was not satisfied with the old one.
B.Because he wanted to create music of his own.
C.Because he was tired of his father's music-teaching method.
D.Because he wanted to show respect for Bach and Rachmaninov.
2.By mentioning Shakespeare, the author wants to tell us______.
A.there is no true creativity in music.
B.Shakespeare9s plays are totally original.
C.many of Shakespeare,s plays deserve no praise.
D.originality is connected with what has already existed.
3.We can conclude from the passage that______.
A.creativity is to find something beautiful.
B.adaptation has nothing to do with creativity.
C.a masterpiece can be a changed version of an existed work.
D.common people don't have the ability to create something new.

It was a morning in January. The jet stream (急流)had dipped down, causing the Arctic cold to reach the mountains of my home. It was only 2 degrees outside, but the cold wind made it feel like it was 15 below zero. Still, I was kneeling in the snow alongside my house trying to open a tiny door, so I eoukl get in. 1 had forgotten to leave my water dripping the night before and now my water pipes were frozen and my faucets(水龙头)were dry.
The wind cut into me like a knife while I struggled to get two electric heaters in place around the section of frozen pipes. The waterlines were buried except for a small piece that connected up to my house. I put a heater on each side of it, ran the extension cords(软线)into my house and plugged them in. Both heaters roared to life and started blowing hot air on the frozen water pipes. My fingers had already started to go numb, so I stayed inside to wait. I could only hope that this bit of warmth could get my water flowing again. Finally, after twenty minutes, the water started flowing through my faucets again. I went back outside into the biller cold and gathered my heaters up. I looked at the weak January sun shining on the frozen snow and smiled. Then I sent a joy filled with "Thank you" heavenward and returned inside to make myself a hot breakfast.
Sometimes the coldness of this life can get to us as well. It can make our hearts feel icy and frozen. It can keep our kindness and love from flowing out to others. Sometimes, though, all we need is a bit of warnth to get us going again. It can be a simple smile, a kind word, a heart-felt hug, a morning sunrise, a bird's song or any gentle reminder of just how much God loves us. Let us all be grateful for those bits of warmth that gel us going again. And let us all try to be that bit of wannth for others every chance we get.
1.What was the direct reason why the water pipes were frozen?
A. The jet stream.
B. The low temperature.
C. The cold wind.
D. The author ' s own carelessness.
2.Which of the following can replace the underlined phrase "roared to in Paragraph 2?
A. Began functioning smoothly.
B. Worked inappropriately.
C. Broke down suddenly.
D. Screamed out loudly.
3.What did the author think of his work?
A. Embarassed.
B. Satisfied.
C. Mad with joy.
D. Cautiously optimistic.
4.What is the last paragraph mainly centered on?
A. The coldness of life has a negative effect on our life quality.
B. We meet with the coldness of life unavoidably and unwillingly.
C. We should be thankful for bits of warmth of life.
D. We should seize every chance to receive warmth of life from others.

Café en Seine The wildly luxury (奢华) new art style of this huge bar has been a huge hit since it first opened in 1995, and while it may not be the “in” place it once was, it is still very popular with the after-work crowd and out-of-towners.
