How much do you know about A．I．(Artificial Intelligence)?Artificial means‘man-made’，and intelligence means‘the ability to learn．understand and think about things’．A．I．is about making machines think，talk，do and see．A．I．is used in many fields from、playing games to helping doctors．Many machines around us work very well because they work with the help of A．I．Man has always dreamed of building‘thinking machines’．In 1770，Wolfgand Kempelen(1 734—1804)built a wooden robot called Turk that was able to play chess(SUR)．It played very well and even beat some of the top chess players of the time! Later it was found that Turk was not real．Inside the box machine was a chess player．

     John McCarthy(1927—)is thought as the‘Father’of A．I He invented the word‘A．I．’and the LISP computer programming language that many A．I．developers use today．How does A．I．work?

3.We can learn from the passage that_________．

     A．we still do not know how A．I．works

     B．computers are the most important part of A．I．

     C．Wolfgand Kempelen was the first builder of robot．

     D．John McCarthy is good at playing chess．

Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.

“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.
