A

In a mountainous area of Brazil， there is a kind of beautiful butterfly which can kill men. If people meet them， they will come down in great quantities to bite and kill， sucking （吸） blood and eating flesh through the wounds they cause.

In June， 1966， a boy named Marl Andre who went into the mountains in search of butterfly specimens （标本） was killed by these butterflies. A country boy saw him as he was just about to raise his net to catch a butterfly. Suddenly thousands of butterflies came down upon him， covering him all over. The boy struggled and cried as he tried to free himself from their attack. Finally he fell senseless to the ground. Police examined his body and proved that he had died of bites by butterflies.

In New Guinea， there is a kind of needlefish which also kills men. Because it likes light at night， it will swim near the lights of fishing boats， then suddenly shoot out of water like an arrow to its target， and force its 3-inch sharp mouth into a human body. Often people are thrust （戳） in the eye， or through the chest or stomach， resulting in death. Sometimes it will even attack the people in a fishing boat in broad daylight.

About 10 persons in the world are killed by sharks every year， yet more than 20 are killed by needlefish every month.

B

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 （释放） of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past ten years. Scientists predict that with climate warming， fires may occur more frequently over 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 catch 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 （辐射） 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 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 leads to cooling results. Specifically， they determined when fire returns 20 years earlier than predicated， 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 got or lost from the earth.

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

A. result in a warming climate

B. lead to a longer fire season

C. protect the forests and the environment there

D. cause the forest fires to occur more frequently

6. Earlier studies about northern forest fires ___ .

A. indicate that forest fires will pollute the atmosphere

B. suggest that the fires will speed up climate warming

C. analyze all aspects of how northern fires influence climate

D. suggest that people should take measures to protect environment

7. The underlined phrase “soaked up” probably means “___” .

A. released B. absorbed

C. created D. distributed

8. 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. help to get more energy rather than release more energy

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

D. allow more snow to mirror more sunlight into space and thus cool the climate
