The 37-year-old Carnegie Mellon University professor has spent years developing snake-like robots he hopes will eventually slide through fallen buildings in search of victims trapped after natural disasters or other emergencies.
Dan Kara is president of Robotics Trends, a Northboro, Mass.-based company that publishes an online industry magazine and runs robotics trade shows. He said there are other snake-like robots being developed, mainly at universities, but didn’t know of one that could climb pipes.
The Carnegie Mellon machines are designed to carry cameras and electronic sensors and can be controlled with a joystick(操纵杆). They move smoothly with the help of small electric motors, or servos, commonly used by hobbyists in model airplanes.
Built from lightweight materials, the robots are about the size of a human arm or smaller. They can sense which way is up, but are only as good as their human operators, Choset added.
Sam Stover, a search term manager with the Federal Emergency Management Agency based in Indiana, said snake-type robots would offer greater mobility than equipment currently available, such as cameras attached to extendable roles.
“It just allows us to do something we’ve not been able to do before,” Stover said, “We needed them yesterday.”
He said snifter dogs are still the best search tool for rescue workers, but that they can only be used effectively when workers have access to damaged building.
Stover, among the rescue workers who handled the aftermath (后果) of Hurricane Katrina, said snake robots would have helped rescuers search flooded houses in that disaster.
Choset said the robots may not be ready for use for another five to ten years, depending on funding.

举一反三
Indonesia’s reefs are vast – they cover 51, 000 square kilometers, surround 17, 500 islands and stretch 3,500 kilometers – but they are not infinite. Many foreign experts and Indonesians fear that the region’s entire marine environment could be seriously damaged if the reefs keep dying at their present rate. “The overall picture is depressing,” says Ian Dutton, Indonesian director of an environmental group.
Depressing, but not hopeless. Despite the destruction, environmentalists have in recent years made significant progress in changing the hearts and minds of the fishermen. Working closely with local Indonesian authorities in North Sulawesi and less populated eastern Indonesia, where most of the country’s reefs are located, they have succeeded in preventing destructive fishing practices and coral mining from overwhelming the reefs.
Increasing numbers of fishermen are waking up to the threat and protecting the life-sustaining coral before it’s too late. Nuhung, a 56-year-old fisherman, says, “I always knew blast fishing was harmful. Then I suddenly realized that by bombing the reefs I was destroying not only my own but my children’s future.”
小题1:The fishermen are named “worst offenders” because .
| A．they defend their rights of mining the coral reefs too eagerly |
| B．they wake up too late to realize the terrible situation |
| C．they use the fishing ways, which destroy the coral reefs |
| D．they pretend to follow the government’s rules |
| A．presents us some facts and people’s opinions as well |
| B．shows that he’s worried about the situation, but still feels a little hopeful |
| C．says he’s delighted and meanwhile, depressed |
| D．disagrees with what’s being done and gives suggestions |
| A．incomplete | B．short | C．unfit | D．limitless |
| A．But for the fishermen’s protection, the reefs would disappear soon. |
| B．More and more fishermen have realized their mistakes. |
| C．Without the coral reefs, the fishermen would have nothing for their livelihood. |
| D．Some practical measures have been taken to stop the situation worsening. |
| A．a magazine | B．a novel | C．a newspaper | D．a storybook |
If Dick Drew had listened to his boss in 1925, we might not have a product that we now think of as of great importance: a new type of tape. Drew worked for the Minnesota Mining Company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Drew improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their work time just thinking about and developing new ideas.
Creativity is not something one is just born with, nor is it necessarily a character of high intelligence. The fact that a person is highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something.
Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can give back information but can’t recognize ways to use it in new situations. They may know the rules correctly but they are unable to use them to work out practical problems.
It is important to give children choices. From the earliest age, children should be allowed to make decisions and understand their results. Even if it’s choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money. This is because the most important character of creative people is a very strong desire to find a way out of trouble.
小题1: What did the company where Drew once worked learn from its mistake?
| A．They should encourage people to work a longer time. |
| B．People should be discouraged to think freely. |
| C．People will do better if they spend most of their work time developing new ideas. |
| D．It is necessary for people to spend some of their work time considering and improving new ideas. |
| A．something that most people are born with |
| B．something that depends mainly on intelligence |
| C．a way of using what one has learned to work out new problems |
| D．something that is not important to the character of a person at all |
| A．They give children too many choices. |
| B．They are not strict enough with children. |
| C．They care too much about examination marks. |
| D．They don’t understand the importance of education. |
| A．Reading. | B．Writing. | C．Mathematical skill. | D．Decision-making. |
All discussions of poetry are, in fact, preparations for reading it aloud, and the reading of the poem is, finally, the most telling “interpretation” of it, suggesting tone, rhythm, and meaning all at once. Hearing a poet read the work in his or her own voice, on records or on film, is obviously a special reward. But even those aids to teaching can not replace the student and teacher reading it or, best of all, reciting it.
I have come to think, in fact, that time spent reading a poem aloud is much more important than “analyzing” it, if there isn’t time for both. I think one of our goals as teachers of English is to have students love poetry. Poetry is “ a criticism of life”, and “ a heightening(提升) of life”. It is “an approach to the truth of feeling”, and it “can save your life”. It also deserves a place in the teaching of language and literature more central than it presently occupies.
I am not saying that every English teacher must teach poetry. Those who don’t like it should not be forced to put that dislike on anyone else. But those who do teach poetry must keep in mind a few things about its essential nature, about its sound as well as its sense, and they must make room in the classroom for hearing poetry as well as thinking about it.
小题1:To have a better understanding of a poem, one should________.
| A．discuss it with others | B．analyze it by oneself |
| C．copy it down in a notebook | D．practise reading it aloud |
| A．Extending your life | B．Saving your life |
| C．Criticizing life | D．Heightening life |
| A．to understand life. | B．to enjoy poetry. |
| C．to become teachers. | D．to become poets |
| A．More stress should be laid on the teaching of poetry. |
| B．Poetry is more important than any other subject. |
| C．One cannot enjoy life fully without an understanding of poetry |
| D．Poetry is the foundation of all language and literature courses |
| A．“build a booth” | B．“provide equipment” |
| C．“leave a certain amount of time” | D．“set aside enough space” |
One should be careful, however, of supposing that silent reading came about simply because reading aloud is distraction（分散注意力）to others. Examination of reasons connected with the historical development of silent reading shows that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character.
The last century saw a gradual increase in literacy（读写能力）and thus in the number of readers. As readers increased, so the number of listeners dropped, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the popularity of reading as a private activity in such public places as libraries, trains and offices, where reading aloud would disturb other readers in a way.
Towards the end of the century there was still heated argument over whether books should be used for information or treated respectfully, and over whether the reading of material such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its advantages are, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and magazines for a specialized readership on the other.
By the end of t he century students were being advised to have some new ideas of books and to use skills in reading them which were not proper, if not impossible, for the oral reader. The social, cultural, and technological developments in the century had greatly changed what the term “reading” referred to.
小题1:Why was reading aloud common before the nineteenth century?
| A．Because silent reading had not been discovered. |
| B．Because there were few places for private reading. |
| C．Because few people could read for themselves. |
| D．Because people depended on reading for enjoyment. |
| A．a change in the position of literate people |
| B．a change in the nature of reading |
| C．an increase in the number of books |
| D．an increase in the average age of readers |
| A．the importance of silent reading |
| B．the amount of information provided by books and newspapers |
| C．the effects of reading on health |
| D．the value of different types of reading material |
| A．To explain how present day reading habits developed. |
| B．To change people’s way to read. |
| C．To show how reading methods have improved. |
| D．To encourage the growth of reading. |
The study divided the patients into three groups. In Group A, a dog and a person visited each patient for twelve minutes. Patients in Group B received just a human visitor for twelve minutes. And members of Group C received no visitor, human or canine(犬的).
The dogs would lie on the hospital bed so the heart patients could touch them. The researchers say some patients immediately smiled and talked to the dog and the human visitor. Dogs, in her words, “make people happier, calmer and feel more loved.”
The researchers examined the patients before, during and after the visits. They measured stress levels based on blood flow and heart activity. They say they found a twenty-four percent decrease in the group visited by both a dog and a person. They reported a ten percent decrease in the group visited by a person only. There was no change in the patients without any visit. These patients, however, did have an increase in their production of the hormone epinephrine (epinephrine肾上腺素). The body produces epinephrine during times of stress.
The increase was an average of seven percent. But the study found that patients who spent time with a dog had a seventeen percent drop in their levels of epinephrine. Patients visited by a human but not a dog also had a decrease, but only two percent.
小题1:The author believes that _______.
| A．the dog can take the place of most medicines |
| B．the dog is the most popular pet for man |
| C．the findings of the research cannot be trusted |
| D．visits by a human work better than visits by a dog |
小题3:From the research findings we may conclude that _______.
| A．the less the body produces epinephrine, the better |
| B．the longer a visit lasts, the happier the patient should be |
| C．the patients enjoyed the dogs’ company more than the human visitors’ |
| D．it’s impossible for heart patients to recover without dogs’ visits |
| A．Worried Heart Patients | B．Epinephrine and Stress |
| C．Good Friend to the Heart | D．Three Groups of Patients |
