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 PS400 and it was chosen because it looked like the time-traveling DeLorean in the movieBack To The Future.The car will be driven the 210 miles between Manchester and London powered only by roasted coffee granules  .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   -- about 56 cups of espressos   per mile.The journey will use about 70 kilos of ground coffee which, at supermarket prices of between PS13 and PS26 a kilo depending on brand and quality, will cost between PS910 and PS1,820, or between 25 and 50 times the PS36 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... 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

Ten Chinese PhD students are demanding that Beijing Normal University Professor Yu Dan be away from her television show on CCTV10. They argue that her on-air explanations of Confucius's Analects (<<>> ) are "incorrect and misleading". Yu is known for explaining Confucius's Analects to a TV audience. But some complain that her explanations are unfaithful to Chinese tradition. But Yu doesn't seem to worry too much about her critics, saying, "It's a matter of personal choice. Some like KFC, while others like McDonalds." STEALING some online gamer's password might seem less harmful than credit card theft. It does keep the victim from wearing himself out all night playing. But it is not all that nice, says 19-year-old Zhang Qiwen, in Shanghai. Last August, Zhang accidentally downloaded a Trojan while playing Warcraft. The Trojan is a type of virus used by hackers to steal people's passwords. Overnight the Trojan transferred all the "gold" (game credits) from Zhang's private account to an unknown account. Zhang hopes the police will find and punish the thief, who can also pocket some cash since the stolen "gold" can go on sale online. New England's largest indoor public garden has opened here in a historic park, and officials expect it to become a center for learning about plants as well as a top attraction for visitors. The glass-walled Roger Williams Park Botanical Center, which opened on March 2, offers a tropical garden, an orchid garden, and a Mediterranean room with a collection of citrus trees. The center also has two classrooms and will offer gardening classes provided by the University of Rhode Island. Roger Williams Park, named for the city's 17th-century founder, also has a zoo. The park already attracts more than 2 million visitors a year, and Providence Mayor David Cicilline said that he expects the new center will attract more and more visitors to Providence. We can learn from the passage that   _  . A) there are four gardens in Roger Williams Park Botanical Center. B) No one likes Yu Dan's explanation of Confucius's Analects. C) Yu Dan won't show up on CCTV any more for explanations of Confucius's Analects. D) Some people make money by stealing online gamers' game credits and selling them.

A team of researchers from Oxford University has demonstrated a self-driving car that is different from such cars being tested by Audi, Ford, etc. It' s much cheaper because it's based on off-the-shelf  technology and controlled by an ordinary iPad. Instead of using GPS to understand the location, the car learns routes when a person is driving, and then asks after it's got it down, if the driver would like the computer to take over. As time passes, it's becoming very clear that people believe computers would be better drivers than humans. This has been proven by extensive research that indicates that computers are able to react more quickly to driving conditions, make smarter decisions, don't take risks, and don't make mistakes in concentration. They don't drink either, of course, which means accidents due to drunk driving could be reduced dramatically if the computer could take over when someone needs to get home from the bar. And the team says drivers don't need their cars to know everything about every road, condition or possible danger. Instead, they just need to know how to get from one point to another, and to do a good job of it when asked. To that end, the researchers have added cameras, lasers, a central computer to process information and a regular iPad. In practice, the car would learn how to get to and from places that the driver frequents, such as their work place, the local pub or grocery store. Once it has it down, the computer asks the driver if they' d like a rest. If so, they simply tap the iPad, and the car takes over. It' s very simple and doesn't require nearly the same number of devices as those being tested by other car companies. The researchers say people might be able to get the total price of the system below a hundred dollars. And of course, the iPad can be lifted out and carried away for other purposes when not being used as a driver assistant. Computers are believed to be better drivers than humans mainly because they   _  . A) are more likely to take risks B) are more familiar with every road C) become more skilful at avoiding dangers D) can respond to new situations more quickly
