But in the earthquake capitals of the worldJapan, Los Angeles, Turkeyrats will soon be mans new best friends. What happens after an earthquake? We send 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 cant 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 rats 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 rats 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 Linter at Cornell UniversityNew York says, “Robots noses dont 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 dont need electricity! The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be wonderful. A rat could get into spaces we couldnt get to and a rat would get out if it wasnt 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)文章大意：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。1In the world earthquake capitals, rats will become mans best friends because they can B .Atake the place of mans rescue jobsBfind the position of people alive who are trapped in buildingsCserve as food for people alive who are trapped in buildingsDget into small spaces解析：推理判断题。根据第二段最后两句But dogs are big and they cant get into small spaces.
