5.Everybody hates rats But in the earthquake capitals of the world-Japan,Los Angeles,Turkey-rats will soon be man's new best friendsWhat happens after an earthquake?We sent in rescue dogs.Why?Because they can smell people.Dogs save lives They help rescuers to find living people.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.
How does it work?First,the rat is trained to smell people When this happens,the rat's brain gives a signal(信号).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.
Although there are already robots which can do this job,rats are better Christian Linster at Cornell University,New York,says,"Robots'noses don't work well when there are other smells around Rats are good at that"Rats can also see in the dark They are cheaper and quicker to train than dogs,and unlike robots,they don't need electricity!
The"rat project"is not finished,but Julie Ryan of International Rescue Corps in Scotland says,"It would be fantastic.A rat could get into spaces we couldn't get to and a rat would get out if it wasn't safe"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 ).

分析 地震过后的搜救工作往往会遇到很多问题,幸存者在哪儿?怎样判断残垣断壁下是否还有生命的存在?我们知道有生命探测仪,有搜救犬,你听说过搜救鼠吗?令人厌恶的老鼠在探测生命迹象的时候却具有更多的优势,本文意在介绍搜救鼠独特的优势.
解答 21.答案:B 推理判断题.根据第二段最后两句"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,让老鼠钻入狭小空间中去探测幸存者的位置.
22.答案:C 推理判断题.根据第三段第四句中:"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 细节理解题.根据第四段中"…Robots'noses don't work well when there are other smells around.Rats are good at that."可知,当周围有别的气味的时候,机器人的嗅觉就失效了.
24.答案:A 细节理解题.根据第二段最后两句:"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项为其优点,不符合题意.根据第四段最后一句"They are cheaper and quicker to train than dogs,and unlike robots,they don't need electricity!"可知B、C两项为其优点,不符合题意.文章最后一段提到将老鼠用于救援这个想法太奇妙了,并不是说老鼠比其他动物奇妙,故A项符合题意.
25.D 推理题.根据文章最后一句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).说明现在还没有投入使用,是将来的事情,故使用将来时.故D正确.
点评 文章介绍了在救援方面使用老鼠的优势.本文主要考查了细节题,注要求考生注重综合语言能力的运用,结合语境,做出准确的判断.

If Mr.Winterkorn was not responsible,who was?Nobody believes that the handful of senior managers could have (61)C this scheme without any support.Hans-Dieter Potsch,a supervisory board chairman,issued a statement earlier this month,saying it would take time before Volkswagen could make (62)B the findings of its internal investigations."We must overcome the crisis,"he explained,"but we must also ensure that Volkswagen continues to grow."That seems to miss the point that Volkswagen will neither overcome the crisis nor grow unless it can instantly produce some (63)A answers and explanations.
