PITTSBURGH — For most people, snakes seem unpleasant or even threatening. But Howie Choset sees in their delicate movements a way to save lives.

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 (操縱桿). 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 sniffer 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.

1.Which institution is responsible for the development of Choset's robots?

A. Robotics Trends. B. Pittsburgh City Council.

C. Carnegie Mellon University. D. Federal Emergency Management Agency.

2.Choset believes that his invention _________.

A. can be attached to an electronic arm

B. can be used by hobbyists in model airplanes

C. can find victims more quickly than a sniffer dog

D. can sense its way as well as its operators

3.By saying "We needed them yesterday" (paragraph 7), Stover means that snake-like robots ________.

A. could help handle the aftermath of Hurricane Katrina

B. should have been put to use in past rescue work

C. helped rescuers search flooded houses yesterday

D. were in greater need yesterday than today

4.What is the text mainly about?

A. Snake-like robots used in industries.

B. Snake-like robots made to aid in rescues.

C. The development of snake-like robots.

D. The working principles of snake-like robots.

Middle school graduation style may be a bit more casual than formal high school or college ceremonies,but the move from junior to senior high school is still an important occasion that can be celebrated in many ways.

The decision whether students will wear caps and gowns（禮服）for middle school graduation is usually up to the individual school.Some feel that this is the perfect way to commemorate the special occasion,while others feel the cap and gown is unnecessary for a junior high ceremony.

For those schools that choose not to use caps and gowns,it is typically suggested that students wear dress clothes for the occasion.Students may also be encouraged to dress for graduation in a uniform manner,such as white shirts and black pants or skirts,or educators may suggest dressing in the school colors.Schools that choose to have students wear academic regalia（制服）for the ceremony may choose to purchase gowns in a variety of sizes from a store such as Graduate Affairs,and then let students borrow them,and reuse them each year.Caps may be purchased by a Parent-Teacher Organization or by the individual graduates.
