13、ET 1. 20 There was a time when parents who wanted an educational present for their children would buy a typewriter, a globe or an encyclopedia set.

Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1. 40 The destruction of our natural resources and contaminatio

23、n of our food supply continue to occur, largely because of the extreme difficulty in affixing (把 固定 ) legal responsibility on those who continue to treat our environment with reckless abandon (放任 ). Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been m

24、et by lawsuits, personal and industrial denial and long delays-not only in accepting responsibility, but more importantly, in doing something about it. It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is indust

25、ry s and our recognition that protecting mankind s great treasure is the single most important responsibility? If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental problems, that time is now. We are being asked, and

26、, in fact, the public is demanding that we take positive action. It is our responsibility as professionals in environmental health to make the difference. Yes, the ecologists, the environmental activists and the conservationists serve to communicate, stimulate thinking and promote behavioral change.

27、 However, it is those of us who are paid to make the decisions to develop, improve and enforce environmental standards, I submit, who must lead the charge. We must recognize that environmental health issues do not stop at city limits, county lines, state or even federal boundaries. We can no longer

28、afford to be tunnel-visioned in our approach. We must visualize issues from every perspective to make the objective decisions. We must express our views clearly to prevent media distortion and public confusion. I believe we have a three-part mission for the present. First, we must continue to press

29、for improvements in the quality of life that people can make for themselves. Second, we must investigate and understand the link between environment and health. Third, we must be able to communicate technical information in a form that citizens can understand. If we can accomplish these three goals

30、in this decade, maybe we can finally stop environmental degradation, and not merely hold it back. We will then be able to spend pollution dollars truly on prevention rather than on bandages. 41 We can infer from the first two paragraphs that the industrialists disregard environmental protection chie

31、fly because _. （ A） they are unaware of the consequences of what they are doing （ B） they are reluctant to sacrifice their own economic interests （ C） time has not yet come for them to put due emphasis on it （ D） it is difficult for them to take effective measures 42 The main task now facing ecologi

32、sts, environmental activists and conservationists is _. （ A） to prevent pollution by legislation, economic incentives and persuasion （ B） to arouse public awareness of the importance of environmental protection （ C） to take radical measures to control environmental pollution （ D） to improve the qual

33、ity of life by enforcing environmental standards 43 The word “tunnel-visioned“ (Line 2, Para. 4) most probably means“ _ “. （ A） narrow-minded （ B） blind to the facts （ C） short-sighted （ D） able to see only one aspect 44 Which of the following, according to the author, should play the leading role i

34、n the solution of environmental problems? （ A） Legislation and government intervention. （ B） The industrys understanding and support. （ C） The efforts of environmental health professionals. （ D） The cooperation of ecologists, environmental activists and conservationists. 45 Which of the following is

35、 true according to the last paragraph? （ A） Efforts should be exerted on pollution prevention instead of on remedial measures. （ B） More money should be spent in order to stop pollution. （ C） Ordinary citizens have no access to technical information on pollution. （ D） Environmental degradation will

36、be stopped by the end of this decade. 45 In the 1950s, the pioneers of artificial intelligence(AI)predicted that, by the end of this century, computers would be conversing with us at work and robots would be performing our house work. But as useful as computers are, theyre nowhere close to achieving

37、 anything remotely resembling these early aspirations for humanlike behavior. Never mind something as complex as conversation: the most powerful computers struggle to reliably recognize the shape of and object, the most elementary of tasks for a ten-month-old kid. A growing group of AI researchers t

38、hink they know where the field went wrong. The problem, the scientists say, is that AI has been trying to separate the highest, most abstract levels of thought, like language and mathematics, and to duplicate them with logical, step-by-step pro grams. A new movement in AI, on the other hand, takes a

39、 closer look at the more roundabout way in which nature came up with intelligence. Many of these researchers study evolution and natural adaptation instead of formal logic and conventional computer programs. Rather than digital computers and transistors, some want to work with brain cells and protei

40、ns. The results of these early efforts are as promising as they are peculiar , and the new nature-based AI movement is slowly but surely moving to the forefront of the field. Imitating the brain s neural (神经的 ) network is a huge step in the right direction, says computer scientist and biophysicist M

41、ichael Conrad, but it still misses an important aspect of natural intelligence. “People tend to treat the brain as if it were made up of color-coded transistors,“ he explains. “But its not simply a clever network of switches. There are lost of important things going on inside the brain cells themsel

42、ves. “Specifically, Conrad believes that many of the brains capabilities stem from the pattern-recognition proficiency of the individual molecules that make up each brain cell. The best way to build an artificially intelligent device, he claims, would be to build it around the same sort of molecular

43、 skills. Right now, the notion that conventional computers and software are fundamentally incapable of matching the processes that take place in the brain remains controversial. But if it proves true, then the efforts of Conrad and his fellow Al rebels could turn out to be the only game in town. 46

44、The author says that the powerful computers of today _. （ A） are capable of reliably recognizing the shape of an object （ B） are close to exhibiting humanlike behavior （ C） are not very different in their performance from those of the 50s （ D） still cannot communicate with people in a human language

45、 47 The new trend in artificial intelligence research stems from _. （ A） the shift of the focus of study on to the recognition of the shapes of objects （ B） the belief that human intelligence cannot be duplicated with logical, step-by-step programs （ C） the aspirations of scientists to duplicate the

46、 intelligence of a ten-month-old child （ D） the efforts made by scientists in the study of the similarities between transistors and brain cells 48 Conrad and his group of AI researchers have been making enormous efforts to _. （ A） find a roundabout way to design powerful computers （ B） build a compu

47、ter using a clever network of switches （ C） find out how intelligence developed in nature （ D） separate the highest and most abstract levels of thought 49 Whats the authors opinion about the new AI movement? （ A） It has created a sensation among artificial intelligence researchers bu will soon die o

48、ut. （ B） Its a breakthrough in duplicating human thought processed. （ C） Its more like a peculiar game rather than a real scientific effort. （ D） It may prove to be in the right direction though nobody is sure of its future prospects. 50 Which of the following is closest in meaning to the phrase the

49、 only game in town“(Line 3, Para. 4) ? （ A） The only approach to building an artificially intelligent computer. （ B） The only way for them to win a prize in artificial intelligence research. （ C） The only area worth studying in computer science. （ D） The only game they would like to play in town. 50 Theres simple premise behind what Larry Myers does for a living: If you can smell it, you can find it. Myers is the founder of A
