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.

试题【PITTSBURGH – For most people, snakes seem unpleasant or even threatening. But Ho】；主要考察你对题材分类等知识点的理解。[详细]
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 |
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” |
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 |
Photographs are everywhere. They decorate (装饰) the walls of homes and are used in stores for sales of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the beauties of nature. They can also bring things close that are far away. Through photos, people can see wild animals, cities in foreign lands, and even the stars in outer space. Photos also tell stories.
Reporting the news through photos is called photojournalism. At times photojournalists tell their stories through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. It can also be a strong force for social change.
Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the poor lived. Riis believed that poverty(贫穷) caused crime, and he used photos to help him prove his point. A few years later, the photos of small children working in factories by Lewis Hine shocked the public. Hine’s pictures helped bring about laws to protect such children.
Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of what they see. A photo, however, can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture.
As historical and artistic documents(文献) ,photos can become more important over time. Today photojournalists still have their pictures appear in newspapers and magazines. They also publish(发表) them in books and on the Internet.
小题1:The underlined word “They” in the first paragraph refers to .
| A．beauties | B．photos | C．goods | D．events |
| A．are also works of art | B．are popular ways of reporting news |
| C．often shock the public | D．can serve as a force for social change |
| A．News with pictures is encouraging. | B．Photos help people improve |
| C．News photos mean history in a sense. | D．People prefer reading news with pictures. |
| A．telling the story through picture | B．decorating the walls of homes |
| C．publishing historical papers | D．expressing feeling through pictures |
This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: “an interesting week of poetry.” This class was part of a study to answer the questions: Why is science difficult for many nonscience students? What can teachers learn about teaching if they take a class that is not in their field?
The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing – the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn’t write anything on the board.
The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers (层次) of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn’t happen much in undergraduate(本科) science classes, but it is important later, in graduate school. And it is always important in humanities(人文科学).
Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, “We need to change the way we teach engineering to make to make it an enjoyable experience for students.”
But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better.
小题1:What do we know about this unusual class?
| A．The teachers did lots of writing on the board |
| B．The teacher were invited to attend several lectures. |
| C．The student were professors from a university |
| D．The students were studying science and humanities. |
| A．how to teach the students in the science class |
| B．whether poetry is difficult for science students |
| C．what to be taught in the humanities class |
| D．why many humanities students find science hard. |
| A．important for graduate students in humanities |
| B．difficult for graduate students in humanities |
| C．common for undergraduate students in science |
| D．easy for undergraduate students in science. |
| A．They should change the way they teach |
| B．A poem could be explained in clear definitions. |
| C．A poetry class could be more informative. |
| D．Their teaching was an enjoyable experience. |
