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... How much ground coffee will be used to cover a distance of 126 miles in this car? A) About 70 kilos B) About 42 kilos. C) About 32 kilos D) About 30 kilos

Two thieves came to a house to steal something. They dug a hole in the wall of the house. There lived many mice in the house. The woman in the moonlight saw a mouse crawl into the house."Look!In comes one,"she said to the man in the house. The thief was so frightened that he hurriedly crawled out of the house and said to the one waiting outside,"She found me when I was just in." But the thief outside didn't believe him,so he said,"Let us two try to crawl into the house together."At that time two mice happened to crawl into the house,too. The woman saw the mice and shouted,"In come two,catch them!" The two thieves were terribly frightened. The man in the house said,"You saw them come in but where are they? I will catch them tonight."The two thieves started running away at once. The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the womanwere ploughing in their fields. The rein broke and the woman came home for a rope. She saw two men selling sweet potatoesand wanted to buy some. She picked out two which looked like mice. At the time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said,"How they look like the two of last night."The man said,"I asked you to fetch a rope,why don't you hurry for it?"The two thieves ran away quickly without their sweet potatoes. Which of the following statements is FALSE? A) The two thieves not only failed to steal things but also lost their sweet potatoes. B) Whenever they found mice,the people in the house would try to catch them. C) The two thieves ran away at once,because they thought the woman had seen them. D) The man let the woman go home for a rope,which would be used for catching the thieves.

When we think about giving help to developing countries, we often think about giving money so that these countries can build schools and hospitals, buy food and medicine, or find clean water supplies. These seem to be the most important basic needs of the people we are trying to help. However, it's far from enough. Ladies and gentlemen, we've got to come up with some better ideas to help them. I was very surprised, then, when I read about a plan to make cheap laptop computers for children in developing countries. A man called Nicholas Negroponte invented a cheap laptop computer, which can run without electricity. He decided to invent this computer after he visited a school in Cambodia. The laptop which Mr. Negroponte has designed is a little different from the normal laptop computers you can buy in the shops. One difference is that it is covered in rubber so that it is very strong and won't be damaged easily. As an electricity supply can be a problem in developing countries, the computer also has a special handle so that children can wind the computer up to give it extra power when needed. These special laptop computers will cost less than 100 US dollars and Mr. Negroponte wants to build as many as 15 million machines in the first year of production. The idea is that these computers will help the children's education as they will be able to access the Internet. These computers might not help the people in developing countries immediately, but by improving children's education they should help people to find their own solutions to their problems in the long term. Another idea to help children in developing countries is to recycle old mobile phones so that they can be used again. In the UK, and, probably in many other countries too, millions of mobile phones are thrown away every year. The waste created by throwing away these old phones is very bad for the environment, so it seems to be an excellent idea to recycle them. In this way we will be able to achieve two important goals at the same time. We will reduce... It's an excellent idea to recycle old mobile phones because    _   . A) it reduces waste and can help others B) it prevents waste and can earn lots of money C) it can send the waste produced by developed countries to other countries D) it is good for the environment and very educative for phone users
