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(蒸馏)into alcohol to power cars and farm machinery.
And because sellers reject 360,000 tons of“substandard”fruit annually in America alone they 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 cosmetic imperfections,and currently ploughed back into the field.
About a fifth of each.annual watermelon crop is left in the field because of surface blemishes(瑕疵)or because they are misshapen.
Dr Wayne Fish,who led the team,found that 50 per cent of the fruit was fermentable(可发酵的)into alcohol which could provide valuable fuel.
“We've shown that the juice of these melons 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 per cent 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 per cent of the fuel sold at the pump by 2010 to be biofuel.
1.The passage mainly tells us .
A.western countries aim at producing biofucls
B.watermelons could be used to make fuel
C.the advantages of fuel made from watermelons
D.watermelon juice will be the largest source of renewable energy
2.Which of the following NOT the reason why so many watermelons are deserted in America each year?
A.They are substandard. B.They are imperfect.
C.They are misshapen. D.They are oversupplied.
3.It can be learned from the text that .
A.sellers in the world throw away 360,000 tons of watermelons every year
B.about two gallons of fuel could be made.from rejected fruit per acre
C.half of the watermelons were fermentable into alcohol to provide energy
D.five percent of fuel is required to be biofuel from watermelons by 2010 in Britain
4.The underlined word“cosmetic”in Paragraph 5 probably means .
A.inside B.flavor C.surface D.freshness
5.We can infer from the passage that .
A.western countries are engaged in biofuel study but still have a long way to go
B.the EU is likely to meet its target of transport fuels from biological sources
C.it will cost a lot to make biofuel from watermelons
D.watermelon juice has been used as a source of sugars to produce alcohol biofuel

Beijing had its biggest snowfall since 1951.Britain is suffering through its longest cold snap(寒潮)since 1981.And freezing weather is hitting the Deep South,including Florida’s orange groves and beaches.
Whatever happened to global warming?
Such weather doesn’t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases.But experts say the cold snap doesn't contradict global warming at all--it's just a temporary phenomenon in the long-term heating trend."It's part of natural variability," said Gerald Meehl, a senior scientist.With global warming, he said, "we'll still have record cold temperatures.We'll just have fewer of them."
Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes.But experts did not connect the current cold snap to climate change.
So what is going on?
"We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere", Arndt said.
In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics.This air flow acts like a fence to keep Arctic air restricted.But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south.If yon live in a place where it brings air up from the south, you get warm weather.In fact, record highs were reported this week in Washington state and Alaska.
But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north.And that's how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain.The zigzag pattern arises naturally from time to time, but it is not clear why it's so strong right now.
1.What is the best title of the text?
A.Freezing weather is hitting the Deep South.
B.We'll still have record cold temperatures.
C.The air flow has become a zigzag pattern.
D.Cold snap doesn't contradict global warming.
2.With global warming, we will______.
A.also meet with severe cold snap
B.have more hot temperatures forever
C.never experience cold temperatures
D.have more cold temperatures
3.According to experts, the current cold snap______.
A.suggests that the climate has changed greatly
B.is not related to the climate change
C.shows that the climate will turn cold
D.is affected by global warming
4.Beijing had its biggest snowfall since 1951 because of______.
A.a fence from the Arctic B.a cooling trend in climate
C.a big outbreak of Arctic air D.its large population
5.We can conclude that
A.not all the parts of the Northern Hemisphere are cold in face of the cold snap
B.the zigzag pattern arises naturally accidentally
C.Beijing will get cold weather next year
D.Washington state and Alaska will not face cold weather next year
