3.In 1637 the French philosopher-mathematician Rene Descartes predicted that it would never be possible to make a machine that thinks as humans do. In 1950, the British mathematician and computer pioneer Alan Turing declared that one day there would be a machine that duplicate human intelligence in every way and prove it by passing a specialized test. In this test, a computer and a human hidden from view would be asked random identical questions, if the computer were successful; the questioner would be unable to distinguish the machine from the person by the answers.Inspired by Turing's theory, the first conference on AI convened at Dartmouth College in New Hampshire in 1956. Soon afterwards an AI laboratory was started at Massachusetts Institute of Technology by John McCarthy and Marvin Minsky, two of the nation's leading AI proponents. McCarthy also invented the AI computer language, Lisp; but by the early 1990s AI itself had not been achieved. However, logic programs called expert systems allow computers to "make, decisions" by interpreting data and selecting from among alternatives. Technicians can run programs used in complex medical diagnosis, language translation, mineral exploration, and even computer design.Machinery can outperform humans physically. So, too, can computers outperform mental functions in limited areas--notably in the speed of mathematical calculations. For example, the fastest computers developed are able to perform roughly 10 billion calculations per second. But making more powerful computers will probably not be the way to create a machine capable of passing the Turing test. Computer programs operate according to set procedures, or logic steps, called algorithms (算法). In addition, most computers do serial processing: operations of recognition and computation are performed one at a time. The brain works in a manner called parallel processing, performing operations simultaneously. To achieve simulated (模拟) parallel processing, some supercomputers have been made with multiple processors to follow several algorithms at the same time.Critics of this approach insist that solving a computation does not indicate understanding, something a person who solved a problem would have. Human reasoning is not based solely on rules of logic. It involves perception, awareness, emotional preferences, values, evaluating experience, the ability to generalize and weigh options, and more. Some proponents of A1 have, therefore, suggested that computers should be patterned after the human brain, which essentially consists of a network of nerve cells.By the early 1990s, the closest approximation to AI was a special silicon chip built to behave like a human brain cell. It was modeled after the internal workings of neurons in the human cerebral context. Unlike the conventional silicon ship, which works in digital mode, the new silicon chip works in analog mode, much the way a human brain cell works.(5分)3.1 According to Turing, a computer can prove to have human-like intelligence in a special test if____(1分)A. the computer gives better answersB. the questioner fails to give identical questionsC. the questioner can't tell between the answers of a person and a computer D. The questioner can't find the person hidden by the computer

3.In the early 1600's, a group known as the Separatists lived in England. They were people who wanted to worship God, study the Bible and pray, but the English laws did not allow them to worship as they desired. They were hunted down, beaten, and locked up.Eventually, they heard about freedom of religion in Holland, and planned to escape. After much hardship, they were allowed to leave England.Now called Pilgrims, they lived in Holland for 12 years, but left because they couldn't stand the hard life, and couldn't work their own trades. They wanted to find a Kingdom of God for their posterity (后代) to practice religion freely. So they hired the Speedwell and the Mayflower to carry them across the Atlantic to a new land in America.The Speedwell had many leaks and had to turn back. The Mayflower took in their passengers, making a total of over 100. They sailed two months and three days, cramped and hungry.On November 11, 1620, the Mayflower spotted land. They landed in Province town, Massachusetts. For over a month, they sent men to find the perfect place for them to build their colony. When they finally found a place, they called it Plymouth.Right away they started building homes, knowing winter was near.Unfortunately, a violent storm hit when the houses were not yet finished. The Pilgrims were forced to stay on the cramped (狭窄的) Mayflower for their first winter in the new world. When this winter was over, over half of them had died.The Pilgrims eventually made a good friend who helped them. His name was Squanto. He showed them where fish swam, how to hunt deer, and how to plant corn.Squanto was a Native American who was kidnapped (绑架) earlier in his life and taken to England. This is why he was able to communicate with the Pilgrims.With the help of the Native Americans, there was plenty for everyone to eat that first summer, and also plenty to last for the next winter.The Pilgrims had so much to be thankful for. They gave thanks for good friends, new homes, freedom of religion, and plenty of food in a three-day celebration with their Native American friends.Today we continue the celebration of the Pilgrims and the Native Americans, and call it Thanksgiving.(5分)3.1The Separatists left England in pursuit of____.(1分)A. wealthB. adventureC. an easier lifeD. religious freedom
