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. 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 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. 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.result in a warming climateB.cause the forest fires to occur more frequentlyC.lead to a longer fire seasonD.protect the forests and the environment there（2）The following are all the immediate effects after a forest fire EXCEPT ________. A.large amounts of greenhouse gases enter the atmosphereB.the levels of ozone which is a type of oxygen increaseC.snow on the ground mirrors more sunlight back into spaceD.ashes from the fire fall on the ice surface and take in more radiation from the sun（3）Earlier studies about northern forest fires ________. A.analyze all aspects of how northern fires influence climateB.indicate that forest fires will pollute the atmosphereC.suggest that people should take measures to protect the environmentD.suggest that the fires will speed up climate warming（4）The underlined phrase soak up in the last paragraph most probably means ________. A.releasedB.absorbedC.createdD.distributed（5）From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________. A.warm the climate as the supposition goesB.allow more snow to reflect more sunlight into space and thus cool the climateC.destroy large areas of forests and pollute the faroff sea iceD.help to gain more energy rather than release more energy【答案】 （1）A（2）C（3）D（4）B（5）B 【解析】【分析】本文是一篇說明文，介紹了阿拉斯加、加拿大和西伯利亞的森林大火使氣候變暖，科學家們已經(jīng)發(fā)現(xiàn)，在燃燒的樹木允許更多的雪將更多的陽光反射到太空的地區(qū)可能會發(fā)生冷卻。 （1）考查細節(jié)理解。根據(jù)第二段中的“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”這樣的措施最終導致了北部地區(qū)的氣候變暖。故選A。 （2）考查推理判斷。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候發(fā)生的事情，并不是immediate effects。故選C。 （3）考查細節(jié)理解。根據(jù)第三段中的“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.”可知早期關于北方森林火災的研究建議大火將加速氣候變暖，故選D。 （4）考查推理判斷。根據(jù)最后一段中的““ 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.”可知該詞與send back該詞相反的意思，故應該指吸收，因為send back指反射。故選B。 （5）考查細節(jié)理解。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.”可知從這個研究中得到的結論是B。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇環(huán)保類閱讀，考生需要準確捕捉細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。2．犇犇閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項。 Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn39。t it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand? Now something like a tabletshaped but foldable phone is about to bee available. In February, South Korean electronics pany Samsung and China39。s Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the foldable future, The Verge noted. The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Mean
