Question

You like rats? You must be kidding. Everyone hates rats. But rats may soon be man’s new good friend.

What happens after an earthquake? We send in rescue (營(yíng)救，救援) 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. 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. “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 a scientist says, “It would be great. 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).

【解析】

試題分析：這篇短文主要講述老鼠將來可能成為人類的好朋友。文章介紹，老鼠通過馴化，可以比狗和機(jī)器人更有利于在地震中搜尋生命跡象，也更有利于自身脫離險(xiǎn)境。

1.The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to。這個(gè)項(xiàng)目還沒有結(jié)束，但是科學(xué)家說：這個(gè)項(xiàng)目將會(huì)很偉大，老鼠會(huì)進(jìn)入太空我們無法到達(dá)的地方。這篇文章可能在科技雜志上出現(xiàn)。故選C。

2.細(xì)節(jié)理解題。根據(jù)短文a new research project is using a smaller animal to save lives: the rat.的描述，可知老鼠可以幫助救援人員找到地震中的幸存者。故選D。

3.細(xì)節(jié)理解題。根據(jù)短文第四段的描述可知，選項(xiàng)A、B、D與短文描述相符，但是沒有提及老鼠是否比無線電靈敏。故選C。

4.標(biāo)題歸納題。聯(lián)系上下文，文章主要介紹老鼠通過馴化，可以比狗和機(jī)器人更有利于地震救援，故選D。
