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 ToThe 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.

My 16-year-old son, Anton, had gone to the local swimming hole．Most of the kids swim there, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his safety．
Still, the firefighter's first words "You need to come up here to the Stillwater River" made me catch my breath, and his follow-up words gave me relief: “ Your son is OK．”
When I got to the river, I immediately saw the fire truck, ambulance and Anton, wrapped with a towel about his shoulders, sitting quietly on a low platform of the fire engine．
I hurried over to him. "You OK?"I asked．
“Yeah," was all he said．But my eyes begged for an explanation. I didn't get it from my son, however, who tends to play his cards close to his vest．
The story was this: A woman was being swept under water. Hearing the cries, Anton and his friend Tyler, without hesitation, swam out to her, and brought her safely to shore．
In an age in which the word "hero" is broadcast with abandon and seemingly applied to anyone who make it through the day, I realized the real thing in my son．The teens are stubborn and self-centred, but that didn't mean they have no desire to do good．
Still shocked by my son's daring, I drove him home．Along the way, I tried to dig out some more information from him - but he had precious little to say．The only words he said were,
“What's for supper?"
I spent some time alone that evening, thinking about the tragedy that might have been. The next morning, when Anton got up, I half wanted him to tell me the story．But all he did was toast some bread, pull himself together, and head for the door to start a new day. Watching from the window, I was reminded that still water often runs deep.Why did the mother allow her son to swim there?
| A．He was an excellent swimmer. |
| B．The water of the river is shallow. |
| C．He was old enough to swim. |
| D．The rocks can be of help if there's danger. |
The underlined part "who tends to play his cards close to his vest" probably means ________
| A．Anton is a boy fond of swimming with other kids |
| B．Anton is unwilling to tell others what he thinks |
| C．Anton always has a desire to help others |
| D．Anton seldom changes his mind |
In the mother's eyes, what her son did was__________
| A．dangerous but interesting |
| B．meaningful but difficult |
| C．unexpected and courageous |
| D．awful and absurd |
What might be the best title for the passage?
| A．My Son, My Hero | B．Anton, A Silent Boy |
| C．A Good Deed | D．A Proud Mother |

According to a famous optical(光学) expert, Alexander, who recently visited Shanghai, the developed countries in Europe and America have made rules that children must wear resinous(树脂) glasses instead of the traditional glasses made of glass. This is because the glass glasses are more likely to do harm to children’s eyesight.
Alexander pointed out: wearing the right glasses as soon as possible is still the best way to cure and put right children’s eyesight problems.
In America and Japan the resinous glasses have taken up 80 percent of the glasses market. And some European countries and America have made it a law that children, teenagers and drivers must wear resinous glasses. Now, about 10 million children in China have different eyesight problems and they need timely treatment.
But still, too many parents are buying the traditional glass glasses for their children. This is mainly because many parents know little or nothing about the good points of the resinous glasses. Besides, the price for the new glasses is a little higher than the traditional ones.This news article mainly wants to tell us _______.
| A．Alexander visited China and introduced a new type of glasses |
| B．we should wear resinous glasses instead of glass glasses |
