Passage 64

(06·江苏E篇)

A new eight-kilometre road is under construction that links the port area with the motorway system . It is expected to carry 20,000 trucks and cars a day, which greatly reduces the overcrowded traffic in the center of the city . As part of the project , two four-kilometre road tunnels are being built below the central area of the city , one for traffic to the north and the other for traffic to the south .The two tunnels are about 20 metres below the surface and are 12 metres wide , providing for two lanes of traffic in each direction .

In the upper part of the tunnel two air-conditioning pipes remove the waste gas of trucks and cars and keep the quality of air inside the tunnel . The lighting is at the top of the tunnel , practically at its highest point . There will also be electronic signs at frequent intervals (间隔). They show traffic conditions ahead , and can be seen clearly by drivers . The wall is made up of four main elements , which include a waterproofing covering and , on the inside of the tunnel , a concrete lining (混凝土衬砌).

Each tunnel is roughly round and the lower part of the tunnel is somewhat flat .The surface of the road lies on the base , which is made of concrete and steel　 The drainage system (排水系统), just below the road surface on one side , removes any extra liquid , particularly water . In the event of fire , the fire main , which is made of steel , pipes water to many fire hydrant stations at regular intervals along the length of the tunnel . The fire main is at the side of the tunnel , and at the level of the road surface . Other systems in the tunnel will include emergency phones .

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 no better than its operators

72. 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.

66．What is the main purpose of the passage?

　　　 B．To discuss the scientists ’ problems.

　　　 C．To explain people’s way of life in the past.

　　　 D．To describe the sunken ships.

Passage 63

(06·山东E篇)

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 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 (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.

Passage 62

(06·重庆C篇)

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.

Underwater archaeology –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 archacologists have made more exciting discoveries such as the 5,000-year-old boats in the Mediterranean Sea.

Underwater archacology can provide facts about 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 people’s way of life and their systems of trade in ancient times. Underwater archacologists 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.
