A car that runs on coffee is unveiled(shown to the public for the first time)today but at between 25 and 50 times the cost of running a car on petrol, the invention won’t please any motor industry accountants.
Nicknamed the Car-puccino, it has been created using a 1988 Volkswagen Scirocco bought for £400 and it was chosen because it looked like the time-traveling DeLorean in the movie Back To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules (颗粒).It has been built by a team from the BBC1 science programme Bang Goes The Theory and will go on display at the Big Bang science fair in Manchester to show how fuels other than traditional petrol can power vehicles.
The team calculates the Car-puccino will do three miles per kilo of ground coffee (咖啡粉) — about 56 cups of espressos (浓咖啡) per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between £13 and £26 a kilo depending on brand and quality, will cost between £910 and £1,820, or between 25 and 50 times the £36 cost of petrol for the journey.In total, the trip will cost 11,760 espressos, and the team will have to take ‘coffee breaks’ roughly every 30 to 45 miles to pour in more granules.They will also have to stop about every 60 miles to clean out the ‘coffee filters’ to rid them of the soot and tar which is also generated by the process.So despite a top speed of 60mph, the many stops mean the going will be slow, with the journey taking around ten hours.
Sadly, the inventors will still have to pay duty on their coffee fuel---even though tax collectors at Her Majesty’s Revenue and Custom haven’t yet worked out how much.
Nick Watson, producer of Bang Goes The Theory, said, “Coffee, like wood or coal, has some carbon content so you can use it as a fuel.The coffee needs to be very dry and in granules to allow the air to move through the pile of coffee as it burns.The brand doesn’t matter.” He said the same technology could be used to power a car on other unusual fuels, such as woodchips or nut shells, construction or agricultural waste.
小题1:Which is the right way to choose the coffee used as fuels to run the Car-puccino?
A.It should be very dry.B.The stronger, the better.
C.The smaller the granules are, the better.D.It should be of a certain brand.
小题2:What can be inferred from the passage?
A.All kinds of materials can be used as fuels.
B.The Car-puccino will be put into the market soon.
C.Nick Watson is the designer of the Car-puccino
D.Much remains to be improved for the Car-puccino.
小题3:The Car-puccino has its disadvantages EXCEPT that ________.
A.it makes a lot of noise
B.it runs at a very high cost
C.it has to stop to be refueled very often
D.it’s not good enough for long-distance journey
小题4:How much ground coffee will be used to cover a distance of 126 miles in this car?
A.About 70 kilosB.About 42 kilos.C.About 32 kilosD.About 30 kilos
小题5:Why can coffee be used as a fuel?
A.It looks like wood or coal.B.It contains some carbon content.
C.It is very cheap.D.It is much better than woodchips or nut shells.

When I was born, my parents immediately noticed something wrong. My feet were deformed (畸形的), pointing inward and curling under. I wore casts (石膏) and foot braces (支架) in my first two years to correct the problem. Yet I learned to balance and walk in casts. Soon after the last set of casts came off,Mom enrolled me in dance classes as therapy for my feet. I, however,quickly decided to try something else. Not far from my house was an ice rink (溜冰场) in the mall. There,local skaters would perform ice shows. I wanted to try skating.
I started taking group skating lessons. Performing on ice came naturally. For me,skating has never been about beating others. It’s been about being my personal best. I progressed through various levels rapidly and gave my first ice performance at age seven. Soon I started winning local and regional competitions. That’s because being on the ice has always been the one place I can truly express my emotions. The ice is like home.
I began seriously training when I was nine years old. After graduating from girls’ high school,I moved to Canada. Saying goodbye to my family and friends made me homesick,but I knew deep down that I had to leave and train full-time to give my dreams a chance at reality.
I went to compete in the Olympic Games in 1992.I was the first of the final six skaters on the ice. My long performance started well,but I slipped while landing one of my easiest triple jumps,and my hand touched the ice. I didn’t want to make two mistakes in a row,so next I did a jump with just two spins to play it safe. As I neared the end,I had one more jump. I landed it perfectly.
When medals were awarded,I found myself on the top step,the gold hanging around my neck and America’s national anthem playing. Words can’t describe the overwhelming mixture of emotions I felt.

Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. The teacher’s job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.
It is always more important to know how to study by oneself than to memorize (记住) some facts or a formula (公式). It is usually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn’t get everything from school. But they were all so successful. They invented so many things for mankind.   Above all, they knew how to use their brains.
小题1: Whether he is more ________or less, a teacher can’t teach his students everything they want to know.
A.importantB.usefulC.difficultyD.knowledgeable (有知识的)
小题2:A teacher’s job is mainly to train his students to master the ability of __________.
