【文章內(nèi)容簡介】 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。4．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. Meanwhile, they still fit easily into the pocket. As USA Today noted, they39。re the bination of a small tablet and smartphone, all in a single device. The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space. In a keynote address, Samsung39。s senior vice president of mobile product marketing, Justin Denison, called the foldable screen the foundation for the smartphone of tomorrow. It39。s a blank canvas (畫布) for us to do something beautiful together. he said. So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二極管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That39。s a price that few people will be able to afford. But if the foldable device isn39。t going to change the world overnight, there is no doubt that it is ing. Patrick Moorhead, an industry analyst told The Verge, Few are debating if foldable or rollable mobile displays are the future of smartphones。 the only question is when and by whom.（1）What can be the best title for the text?
