分析 地震過后的搜救工作往往會遇到很多問題,幸存者在哪兒?怎樣判斷殘垣斷壁下是否還有生命的存在?我們知道有生命探測儀,有搜救犬,你聽說過搜救鼠嗎?令人厭惡的老鼠在探測生命跡象的時候卻具有更多的優(yōu)勢,本文意在介紹搜救鼠獨特的優(yōu)勢.
解答 21.答案:B 推理判斷題.根據(jù)第二段最后兩句"But dogs are big and they can't get into small spaces.So now a new research project is using a smaller animal to save lives:the rat."可知,地震救援中,讓老鼠鉆入狹小空間中去探測幸存者的位置.
22.答案:C 推理判斷題.根據(jù)第三段第四句中:"This is sent to a small radio on its back,and then the rescuers follow the radio signals.When the rat's brain activity jumps,the rescuers know that someone is alive.The rat has smelled that person."可知.
23.答案:C 細節(jié)理解題.根據(jù)第四段中"…Robots'noses don't work well when there are other smells around.Rats are good at that."可知,當周圍有別的氣味的時候,機器人的嗅覺就失效了.
24.答案:A 細節(jié)理解題.根據(jù)第二段最后兩句:"But dogs are big and they can't get into small spaces.So now a new research project is using a smaller animal to save lives:the rat."可知D項為其優(yōu)點,不符合題意.根據(jù)第四段最后一句"They are cheaper and quicker to train than dogs,and unlike robots,they don't need electricity!"可知B、C兩項為其優(yōu)點,不符合題意.文章最后一段提到將老鼠用于救援這個想法太奇妙了,并不是說老鼠比其他動物奇妙,故A項符合題意.
25.D 推理題.根據(jù)文章最后一句Perhaps for the first time in history,people will be happy to see a rat in a building (but only after an earthquake,of course).說明現(xiàn)在還沒有投入使用,是將來的事情,故使用將來時.故D正確.
點評 文章介紹了在救援方面使用老鼠的優(yōu)勢.本文主要考查了細節(jié)題,注要求考生注重綜合語言能力的運用,結(jié)合語境,做出準確的判斷.
