Forget chip fat, sugar cane or rapeseed oil -- the latest source of biofuel could be watermelons. Scientists have discovered that the fruit is a great source of sugar that can be readily distilled into alcohol to power cars and farm machinery. And sellers reject 360,000 tons of "substandard" fruit every year in America alone which could be used as an economical way to make fuel. The waste from US growers could produce nearly two million gallons (nine million litres) of biofuel per year. In the study, researchers at the United States Department of Agriculture set out to determine the biofuel potential of juice from rejected watermelons --those not sold due to imperfections, and currently ploughed back into the field. About a fifth of each yearly watermelon crop is left in the field because of surface blemishes or because they are misshapen. Dr. Wayne Fish, who led the team, found that 50 percent of the fruit was fermentable into alcohol which could provide valuable fuel. "We've shown that the juice of these watermelons is a source of readily fermentable sugars, representing an unexploited raw material for alcohol biofuel production," he said. The study, published in the journal Biotechnology for Biofuels, discovered that watermelons could produce around 20 gallons of fuel per acre from fruit that otherwise would go to waste. Production of biofuels has been targeted by Western governments as a way to support renewable energy targets. The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met. The British government's Renewable Transport Fuel Obligation requires five percent of the fuel sold at the pump by 2010 to be biofuel. The passage mainly tells us _ . A) watermelon juice will be the largest source of renewable energy B) the advantages of fuel made from watermelons C) Western countries aim at producing biofuels D) watermelons could be used to make fuel

*Question*
What is funny? The short answer is: Who knows? The joke that causes a burst of laughter from one listener might be met with a puzzled look from another. In general, you should avoid jokes at any business or social gathering where there are more than two people in your conversational group. If there are only two people -- and they consist of you and your best friend -- go ahead and tell it. Admittedly, a few people possess a perfect sense of timing, appropriateness, and joke delivery. You are probably not one of them. You might be quite funny and have many great jokes. But there's a place for jokes -- over dinner with family, hiking with friends, but business or social affairs with colleagues and acquaintances are not it. It takes a whole other level of joke-telling ability to put a joke into the more formal conversations. The best jokes come into the conversation so that by the time listeners realize a joke is in progress, the punchline that produces humour is being delivered -- to their surprise and delight. Jokes don't translate well when you're in a group with mixed backgrounds: those whose first language is not English, those who might not understand a special term or an "in" expression, young people who wouldn't catch a reference to some bit of culture familiar to older people -- and vice versa . Never joke about another person in the group -- about their name, habits, hometown, profession, appearance, or past. It's not a question of whether the joke is cheery or appropriate. No one enjoys being singled out this way. When you are the subject of the joke, the laughter doesn't feel good no matter how hard you try to tell yourself they're not laughing at you. Because that's what it feels like. What do you say if you realize your joke upset someone? Apologize as briefly and as sincerely as you can, and hope that someone changes the subject. Try saying: "I'm sorry. I should have known better" or "I'm sorry. I wasn't thinking." What do you do if people don't get your joke or don't appear to find it as funny... When people do not understand a joke they hear, they tend to _ . A) believe it's the joke-teller's fault B) get someone to retell the joke C) ask for explanation D) say something foolish
