Question

Everybody hates rats. But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.

What 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 (信號). 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(電)!

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 of it 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).

試題分析：文章介紹了用老鼠來尋找在地震中北困在地下的人的優(yōu)勢。

1.推理題。根據(jù)文章第2段. So now a new research project is using a smaller animal to save lives: the rat.和第三段說明人們可以利用老鼠來找到那些被圍困在地下的人，并把他們救出來。故B正確。

2.細節(jié)題。根據(jù)第四段第二行“Robots’ noses don’t work well when there are other smells around.說明機器人的嗅覺是被其他味道干擾，故C正確。

3.細節(jié)題。根據(jù)文章第二段第二行But dogs are big and they can’t get into small spaces.說明老鼠可以到更小的地方，故D是老鼠的優(yōu)勢；根據(jù)第四段第三行They are cheaper and quicker to train than dogs,說明B是優(yōu)勢。根據(jù)第四段最后一行they don’t need electricity!說明C也是老鼠的優(yōu)勢。A沒有提及。故A不是老鼠的優(yōu)勢。

4.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。說明人們還在使用狗和機器人實施求援。故D正確。
