8、. That would be good news for governments, farmers and others seeking to plan for the droughts and heavy rainfall that El Nino can produce in various parts of the world.Using a computer, the researchers matched sea-surface temperatures to later El Nino occurrences between 1980 and 2000 and were then
9、 able to anticipate El Nino events dating back to 1857, using prior sea-surface temperatures. The results were reported in the latest issue of the journal Nature.The researchers say their method is not perfect, but Bryan C. Weare, a meteorologist at the University of California, Davis, who was not i
10、nvolved in the work, said it “suggests El Nino is indeed predictable.“This will probably convince others to search around more for even better methods,“ said Weare. He added that the new method “makes it possible to predict El Nino at long lead timess.“ Other models also use sea-surface temperatures
11、, but they have not looked as far back because they need other data, which is only available for recent decades, Weare said.The ability to predict the warming and cooling of the Pacific is of immense importance4. The 1997 El Nino, for example, caused an estimated $20 billion in damage worldwide, off
12、set by beneficial effects in other areas, said David Anderson, of the European Centre for Medium-Range Weather Forecasts in Reading, England. The 1877 El Nino, meanwhile, coincided with a failure of the Indian monsoon and a famine that killed perhaps 40 million in India and China, prompting the deve
13、lopment of seasonal forecasting, Anderson said.When El Nino hit in 1991 and 1997, 200 million people were affected by flooding in China alone, according to a 2002 United Nations report.While predicting smaller El Nino events remains tricky, the ability to predict larger ones should be increased to a
14、t least a year ff the new method is confirmed.El Nino tends to develop between April and June and reaches its peak between December and February. The warming tends to last between 9 and 12 months and occurs every two to seven years.The new forecasting method does not predict any major El Nino events
15、 in the next two years, although a weak warming toward the end of this year is possible.（分数：7.00）(1).The method used by the Columbia University researchers can predict El Nino a few months in advance.（分数：1.00）A.A.

According to a computer simulation, black soot may be responsib
20、le for 25 percent of observed global warming over the past century.2 Soot in the higher latitudes of the Earth, where ice is more common, absorbs more of the suns energy and warmth than an icy, white background. Dark-colored black carbon, or soot, absorbs sunlight, while lighter colored ice reflects
21、 sunlight.3 Soot in areas with snow and ice may play an important role in climate change. Also, if snow and ice covered areas begin melting, the warming effect increases, as the soot becomes more concentrated on the snow surface. “This provides a positive feedback, as glaciers and ice sheets melt, t

Soot also is believed to play a role in changes in the atmosphere above the oceans and land.5 “Black carbon reduces the amount of energy reflected by snow back into space, thus heating the snow surface more than if there were no black carbon,“ H
24、ansen said. Soots increased absorption of solar energy is especially effective in warming the worlds climate. “This forcing is unusually effective, causing twice as much global warming as a carbon-dioxide forcing of the same magnitude,“ Hansen noted.6 Hansen cautioned, although the role of soot in a
25、ltering global climate is substantial, it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century, Such gases are expected to be the largest climate forcing for the rest of this century.7 The researchers found that observed warming in the Northe

These observations were consistent with the researchers climate model simulations, which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.（分数：8.00）(1).Paragraph

31、million injuries. To reduce car crash rate, much research now is focused on safety and new fuels- though some electric vehicle and biofuel research aims at going faster.Travelling at speed has always been risky. One cutting edge area2of research in motoring safety is the use of digital in-car assist

The use of artificial intelligence software allows these assistants to monitor your driving and makes sure your phone or radio doesnt distract you at a vital moment. Most crashes result from human and not mechanical faults.Some s

Radar can spot obstacles in fog, while other technology “sees through“ high-sided vehicles blocking your view.And improvements to seat belts, pedal controls and tyres are making driving smoother and safer. The colour of a car has been found to be linked
34、 with safety, as have, less surprisingly, size and shape.And alternatives to fossil-fuel based petrol, such as plant oils, are a hot area of research. Fuel cells based on hydrogen burn cleanly, and are the subject of a serious research effort,But whatever is in the fuel tank, you dont want a thief i

These communication systems can also come into play if you crash, automatically calling for help.Accidents cause many traffic jams, but there are more subtle

As well as being a stimulant, caffeine interrupts the flow of melatonin, the brain hormone that sends people into a sleep.Melatonin levels normally start to rise about two hours before bedtime. Levels then peak between 2 am and 4 am, before falling again
43、. “Its the neurohormone that controls our sleep, and tells our body when to sleep and when to wake,“ says Maurice Ohayon of the Stanford Sleep Epiderniology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the bodys levels of t

They also took haft an hour to drop off-twice as long as usual - and jigged around in bed twice as much.In the second phase of the experiment, the researchers woke the volunteers every three hours and asked them to give a urine sample. Shilo measured concentration

In a paper accepted for publication in Sleep Medicine, the researchers suggest that caffeine blocks production of the enzyme that drives melatonin producti
