Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.

    This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.

    This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.

    Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.

    “We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

According to the new findings, taking steps to prevent northern forest fires may __________.

A. result in a warming climate     

B. cause the forest fires to occur more frequently

C. lead to a longer fire season            

D. protect the forests and the environment there

The following are all the immediate effects after a forest fire EXCEPT __________.

A. large amounts of greenhouse gases enter the atmosphere

B. the levels of ozone which is a type of oxygen increase

C. snow on the ground mirrors more sunlight back into space

D. ashes from the fire fall on the ice surface and take in more radiation from the sun

Earlier studies about northern forest fires __________.

A. analyze all aspects of how northern fires influence climate

B. indicate that forest fires will pollute the atmosphere

C. suggest that people should take measures to protect environment

D. suggest that the fires will speed up climate warming

The underlined phrase “soak up” in the last paragraph most probably means __________.

A. released         B. absorbed       C. created      D. distributed

From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.

A. warm the climate as the supposition goes

B. allow more snow to reflect more sunlight into space and thus cool the climate

C. destroy large areas of forests and pollute the far-off sea ice

D. help to gain more energy rather than release more energy

U.S. airlines are seeing a major interruption because of hundreds of flights canceled due to the ash cloud from the Icelandic volcano, but European flight companies will face the biggest losses.
The airline business has been tough: The decline dramatically slowed traffic; February heavy snow forced U.S. airlines to cancel thousands of flights; and now the ashes from the volcano stopped all traffic in and out of northern Europe for days.
"For U.S. flight companies, it'll be a relatively short-term hit," said Michael Boyd, president of Boyd Group International, an aviation (航空學(xué)) consulting firm. "We think right now they're down about $80 million in terms of lost income, and they're down domestically about 80,000 passengers that would have been flying domestically but aren't because they can't get here."
Delta announced that volcano-related interruption grounded about 400 flights until Monday at a cost of $20 million in lost revenues. But compare that to the recent snowstorms, when the airline canceled 7,000 flights and lost $65 million in revenue.
The disruption has created uncertainty for customers, but analysts say U.S. airlines won't face as many costs as you might think. They are not flying in extra planes to handle the passengers in trouble because, airline analyst Robert Mann said, companies simply don't have them.
"Airlines run a very lean operation now," Mann said. "So, since there are no spare aircraft or crews, the airlines will attempt to maximize loads on every one of their aircraft that do fly. But it may take days, or in some cases a week or so, to get some of these customers to where they want to go."
46. Which negative consequences mentioned in the passage did the disasters cause?
A. coldness, pollution and airlines’ losses    
B. airport damage, pollution and slow traffic
C. passenger delay, coldness and airport damage   
D. passenger delay, airlines’ losses and slow traffic
47. Which of the following statements is true according to the passage?
A. The fewest airplanes will fly the trapped passengers to their destinations.
B. All the customers are sure to be sent to their destinations in time.
C. The U.S. and U.K. airlines suffered the same losses in the natural disasters.
D. The volcano eruption reduced the traffic to and from northern Europe.  
48. What does the last paragraph mainly tell us?
A. the troubles that the airlines will face after the ash cloud disappears
B. the measures that the airlines will take to maximize their profit
C. the present situation of the airlines and their plan to deliver the passengers
D. the reasons why the airlines run a fine operation
49. Why will it take a long time for airlines to send the passengers to their different destinations?
A. Because the passengers enjoy staying in airports to talk with one another.
B. Because the airlines don’t have spare planes or employees to serve.
C. Because the airlines don't have enough financial support after the disaster.
D. Because the passengers are asking for full refund from the airlines.
50. The passage is most probably from_______.
A．a(chǎn) novel                                  B．a(chǎn) news report        
C．a(chǎn) magazine                               D．a(chǎn) thesis
