Everybody hates rats(老鼠). 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 send in rescue dogs. Why? Because they can smell people. 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 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.
1. In the world earthquake capitals, rats will become man’s best friends because they can ______.
| A．take the place of man’s rescue jobs |
| B．find the position of people alive who are trapped in buildings |
| C．serve as food for people alive who are trapped in buildings |
| D．get into small spaces |
2.From the third paragraph we know the rescuers can judge a person is alive by ______.
| A．the noise made by the rat |
| B．the rat’s unusual behavior |
| C．the signal sent by the radio on the rat’s back |
| D．the smell given off by the person |
3.In doing rescue jobs, ______.
| A．rats smell better than dogs |
| B．dogs don’t need to be trained to smell people |
| C．robots’ sense of smell can be affected by other smells around |
| D．rats can see in the dark and they are smaller than robots |
4.Rats have all the following advantages EXCEPT that ______.
| A．they are more fantastic than other animals |
| B．they are less expensive to train than dogs |

高一英语单项填空中等难度题查看答案及解析
Scientists in Colombia have trained a team of rats to help remove land mines from the countryside. Land mines are small bombs hidden in the ground and designed to explode(爆炸) when someone steps on them.
When trained, the rats can smell special metals in the mines and then signal(发信号) to their human team. Then why use rats for such an important job?
In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.
The rats have already been used in Tanzania, an African country with many land mines. Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. “They even train their babies to perform their jobs, which saves us a lot of time, ” Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world. Last year, land mines killed 695 people — 56 of whom were children. A criminal group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia’s government. The group has placed mines all around its own bases and in many places in the countryside.
In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救). “These rats will be a great help,” he said.
1.How do rats help to find land mines?
A．By their special sight. B．By their light weight.
C．By their sense of smell. D．By their excellent hearing.
2.The advantage of rats over dogs in finding bombs is that _____.
A．they are cleverer.
B．they run faster
C．they have a better sense of smell
D．they don’t make mines explode as easily
3.The underlined word “They” may refer to ______.
A．scientists B．Wistar rats
C．dogs D．Méndez and her team
4. What is the passage mainly about?
A．Specially-trained rats help clear land mines.
B．People in Tanzania are suffering from land mines.
C．Dogs are no longer used to find land mines.
D．Land mines have become a great danger to Colombians.
