25、WER SHEET 1. 40 Psychologists who adopt a strong behaviorist position deny that emotion experiences are matters for scientific inquiry. In contrast, some biosocial theories hold that emotion feelings must be studied because they are the primary factors in organizing and motivating human behavior. Ac

26、cording to these theories, most of the functions attributed to emotion expressions. Such as empathy and altruism, are dependent on the organizing and motivating properties of underlying emotion feelings. Emotion experiences have several other functions. Several lines of research have shown that indu

27、ced emotion affects perception, learning, and memory. In one study, conducted by Carroll E. Izard and his students, subjects were made happy or angry and then shown happy and angry faces and friendly and hostile interpersonal scenes in a stereoscope. Happy subjects perceived more happy faces and fri

28、endly interpersonal scenes, and angry subjects perceived more angry faces and hospital interpersonal scenes. In this case, emotion apparently altered the basic perceptual process. In another study subjects were made happy or sad and then given happy and sad information about fictional persons and la

29、ter asked to give their impressions and make judgments about the fictional characters. Overall, happy subjects reported more favorable impressions and positive judgments than sad subjects did. These studies provide evidence for the common wisdom that happy people are more likely to see the world thr

30、ough rose-colored glasses. An extensive series of studies indicated that positive emotion feelings enhance empathy and altruism. It was shown by the American psychologist Alice M. Isen that relatively small favors or bits or good luck (like finding money in coin telephone or getting an unexpected gi

31、ft) induced positive emotion in people and that such emotion regularly increased the subjects inclination to sympathize or provide help. Several studies have demonstrated that positive emotion facilitates creative problem solving. One of these studies showed that positive emotion enabled subjects to

32、 name more uses for common objects. Another showed that positive emotion enhanced creative problem solving by enabling subjects to see relations among objects that would otherwise go unnoticed. A number of studies have demonstrated the beneficial effects of positive emotion on thinking, memory, and

33、action in preschool and older children. 41 The main topic of this passage is （ A） psychologists and their personality. （ B） language and emotion. （ C） researches on human emotion. （ D） different types of human behavior. 42 All of the following statements are true EXCEPT （ A） emotion feeling sometime

34、s may change the basic perceptual process. （ B） emotion may affect peoples cognitive processes. （ C） emotion tends to make people unable to solve problems. （ D） some psychologists disagree with some biosocial theories on whether emotion experiences should be studied. 43 In the 2nd paragraph, “to see

35、 the world through rose-colored glasses“ (line 11 ) means （ A） to think the world is pleasantry than it really is. （ B） to perceive the world in a pessimistic way. （ C） to see the world through a pair of red glasses. （ D） to understand that the world is full of red color. 44 It can be inbreed that a

36、 happy person （ A） is more successful than a sad person. （ B） spends less time on his studies. （ C） tends to give unfavorable comments on things now and then. （ D） tends to give favorable impressions about what they encounter. 45 The sentence “positive emotion feelings enhance empathy and altruism“

37、(line 1, paragraph 3) most probably means （ A） positive emotion feelings are sought after by everyone. （ B） positive emotion feelings make people likely to show sympathy and be unselfish. （ C） positive emotion feelings improve ones health greatly. （ D） positive emotion feelings happiness and luck to

38、 ones lives. 45 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 could duplicate hu

39、man 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. Inspir

40、ed by Turings theory, the first conference on AI convened at Dartmouth College in New Hampshire in 1956. Soon afterwards an Al laboratory was started at Massachusetts Institute of Technology by John McCarthy and Marvin Minsky, two of the nations leading AI proponents. McCarthy also invented the Al c

41、omputer language, Lisp; but by the early 1990s Al 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 trans

42、lation, 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 billio

43、n 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. In addition, most computers do serial processing; operations of

44、 recognition and computation are performed one at a time. The brain works in a manner called parallel processing, performing operations simultaneously. To achieve simulated parallel processing, some supercomputers have been made with multiple processors to follow several algorithms at the same time.

45、 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 roles of logic. It involves perception, awareness, emotional preferences, values, evaluating experience, the ability

46、 to generalize and weigh options, and more. Some proponents of AI 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 Al was a special silicon chip built to behav

47、e like a human brain cell. It was modeled after the internal workings of neurons in the human cerebral cortex. Unlike the conventional silicon chip, which works in digital mode, the new silicon chip works in analog mode, much the way a human brain cell works. 46 According to Turing, a computer has h

48、uman-like intelligence in a special test if （ A） the computer gives better answers. （ B） the questioner falls to give identical questions. （ C） the questioner cant tell between the answers of a person and a computer. （ D） the questioner cant find the person hidden by the computer. 47 What significan

49、ce did Turings theory have on the development of AI? （ A） It started the research on AI. （ B） It established the expert system. （ C） It taught technicians how to use complicated programs. （ D） It invented the A1 computer language. 48 In what way is the computer superior to the human brain? （ A） It calculates much faster. （ B） It is more logical. （ C） It does better on the Turing test. （ D） It can perform several operation
