A.cause the forest fires to occur more frequentlyC. 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 cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 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.（1）According to the new findings, taking steps to prevent northern forest fires may ________. A. 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. 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.【英語】高二英語閱讀理解(科普環(huán)保)解題技巧(超強(qiáng))及練習(xí)題(含答案)含解析一、高中英語閱讀理解科普環(huán)保類1．犇犇閱讀下列短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中，選出最佳選項(xiàng)。 This finding suggests that taking steps to prevent northern forest 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 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. 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 faroff 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.result in a warming climateB.lead to a longer fire seasonD.large amounts of greenhouse gases enter the atmosphereB.snow on the ground mirrors more sunlight back into spaceD.analyze all aspects of how northern fires influence climateB.suggest that people should take measures to protect the environmentD.releasedB.createdD.warm the climate as the supposition goesB.destroy large areas of forests and pollute the faroff sea iceD. （1）考查細(xì)節(jié)理解。故選A。根據(jù)第四段中的“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.”可知地上的雪反射陽光這是大火的間接的影響，是在第二年春天的時(shí)候發(fā)生的事情，并不是immediate effects。 （3）考查細(xì)節(jié)理解。 （4）考查推理判斷。故選B。根據(jù)第一段中的“scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.”可知從這個(gè)研究中得到的結(jié)論是B。2．犇犇閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。 Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag.
