D.To describe the sunken ships. 答案 63.B 64.C 65.D 66.A Passage 63 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. 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 ot 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 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.

  When a Swedish ship that sank in 1628 was recovered from the port of Stockholm,historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way,artifacts,objects made by human beings,provided a picture of daily life almost 400 years ago.

  Underwaterarchaeology-the study of ships,aircraft and human settlements that have sunk under large bodies of water-is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment .Besides the Swedish ship wreck(残骸),underwater archaeologists have made more exciting discoveries such as the 5000-year-old boats in the Mediterranean Sea.

  Underwater archaeology can provide facts abut the past.In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of pelples way of life and their systems of trade in ancient times.Underwater archaeologists want to study these objects to add to the world's knowledge of history,but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold,these objects are lost to experts. The second enemy is dredging machines(挖掘机)often used to repair ports.These machines destroy wrecks and artifacts or bury them deeper under sand and mud.By teaching the public about the importance of underwater“museums”of the past,archaeologists are hoping to get support for laws to protect underwater treasures.
