Directions: In this part, there are 2 passages followed by 10 questions or unfinished statements. Read the passages carefully, then answer the questions in the fewest possible words (not exceeding 10 words). Remember to write the answers on the Answer Sheet.
Questions 61 to 65 are based on the following passage.
Scientists say there has been a severe decrease in the amount of water in Lake Chad in northern Africa in the last thirty years. They reported that nature and humans share equal blame for this loss.
In 1963, the fresh-water lake covered 25,000 square kilometers. Now the lake is only about five percent of that size. It measures only about 1,300 square kilometers in the dry season.
Four nations surround Lake Chad. People in Niger, Nigeria, Chad, and Cameroon use it for water, fish and plant life.
Michael Coe and Jonathan Foley, water experts at the University of Wisconsin in Madison, reported on Lake Chad in a science journal. They say the area has suffered from a lack of heavy rain for more than thirty years. This has forced people to build systems to carry water to dry land. These irrigation systems further decrease the amount of lake water.
Mr. Coe says Lake Chad will be only a small body of water in the future. He says people still can get water from the lake to drink and for crops. But he says the lake will no longer provide a healthy environment for fish and plant life.
The researchers used a computer to study what caused the water loss. Their computer study estimated the climate and amount of water in the area. The estimate started with written records from the early 1960s. Then the researchers compared the estimates with the area's recorded climate and water supply for the same period.
The computer study showed results similar to the recorded ones for the first twenty years. But there was a big change in the 1980s. At the time, the lake got smaller much faster than the computer research had estimated.
The researchers say that major irrigation systems were built in the 1980s. The systems took water from two rivers that flow into Lake Chad. The Chari and Logone rivers carry most of the water that enters the lake. The study showed that the increased irrigation reduced the flow in the two rivers. Climate changes also were responsible for the reduction. The flow of the two rivers was reduced by almost seventy-five percent.
Scientists say the problem is expected to worsen in the coming years as the population and demand for water continued to increase.
Questions:
61. The amount of water in Lake Chad is _______.
62. The change in the size of Lake Chad is caused by the climate, _______ and _______.
63. The water from Lake Chad is no longer environmentally appropriate for ________.
64. When did the scientists find that Lake Chad got smaller much faster?
65. The water that the Chari and Logone rivers carry is now _______ percent of the flow of the past.
Questions 66 to 70 are based on the following passage.
For many older people, the modern world is like a foreign country: telephones they can't use; video machines they can't programme; television programmes they can't understand and music they can't stand. Not to mention forgetting everyday things, like names and facts. No wonder that most people think that as we get older, our minds steadily lose their power and effectiveness.
However, recent scientific experiments have shown that it is not necessarily all downhill once you are past 70. In fact, in some important ways, scientists have seen that mental powers actually improve with age. They have demonstrated that we actually get better at making social and personal judgments as we grow older. While older people are not mentally sharper than the young and their eyesight and hearing aren't as good, they seem to have greater wisdom instead.
These discoveries about old people have come about, says Dr. Thomas Hess of North Carolina State University, because scientists have changed the things they are looking at. “We were looking at problem areas, at abnormal brain states, because we were interested in understanding illnesses like Alzheimer's. Now we have started to look at what happens in normal brain function and the position looks
more hopeful.”
In one experiment carried out by Hess, groups of older and younger people were given a list of things that some imaginary people did and were asked to judge their characters for honesty and intelligence. The older group turned out to be much better at saying which people were dishonest or unintelligent.
In another experiment, old and young people were asked to create stories on various themes. These were then written down and read out to judges who didn't know the authors' ages. Again, older people did better.
Even in cases where scientists had previously discovered a weakening with age, such as with memory, new studies have shown that this tendency is not as clear as was once thought. It is true that when told stories, older people are usually poor at remembering details, for example. However, when scientists gave older people stories that mirrored their own experiences—for instance, stories of retirement homes—they were just as good at remembering as young people. Hess believes that this simply shows that older people don't bother to remember things that aren't important to them.
This research seems to show that with age, while we lose the ability to acquire skills, we gain in other ways. Other research has shown that older people are generally happier and have better mental health. All this seems to show that, while the young may not want to admit it, there are many things they could usefully learn from their elders.
Questions:
66. Many old people often feel as if _______ .
67. Recent scientific experiments have shown that, overall, human mental abilities _______ .
68. In the first experiment, Dr. Hess found that older people were _______ .
69. New studies have shown that older people can remember centain things _______ as young

《人工智能与专家系统》试卷（1）参考答案与评分标准 问答题（每题5分，共50分） 1．人工智能是何时、何地、怎样诞生的？（5分） 答：人工智能于1956年夏季在美国达特茅斯（Dartmouth）大学诞生。（3分）1956年夏季，美国的一些从事数学、心理学、计算机科学、信息论和神经学研究的年轻学者，汇聚在Dartmouth大学，举办了一次长达两个月的学术讨论会，认真而热烈地讨论了用机器模拟人类智能的问题。在这次会议上，第一次使用了“人工智能”这一术语，以代表有关机器智能这一研究方向。这是人类历史上第一次人工智能研讨会，标志着人工智能学科的诞生，具有十分重要的意义。（2分） 2．行为主义是人工智能的主要学派之一，它的基本观点是什么？（5分） 答：行为主义，又称进化主义或控制论学派。这种观点认为智能取决于感知和行动（所以被称为行为主义），它不需要知识、不需要表示、不需要推理。其原理是控制论和感知——动作型控制系统。 3．什么是知识表示？在选择知识表示方法时，应该考虑哪几个因素？（5分）答：知识表示是研究用机器表示知识的可行性、有效性的般方法，是一种数据结构与控制结构的统一体，既考虑知识的存储又考虑知识的使用。知识表示实际上就是对人类知识的一种描述，以把人类知识表示成计算机能够处理的数据结构。对知识进行表示的过程就是把知识编码成某种数据结构的过程。（3分）在选择知识表示方法时，应该考虑以下几个因素：(1)能否充分表示相关的领域知识；(2)是否有利于对知识的利用；(3)是否便于知识的组织、维护和管理；(4)是否便于理解和实现。（2分） 4．框架表示法有什么特点？（5分） 答：框架表示法有如下特点：结构性、继承性、自然性。（5分） 5．何谓产生式系统？它由哪几部分组成？（5分） 答：把一组产生式放在一起，让它们相互配合，协同作用，一个产生式生成的结论可以供另一个产生式作为已知事实使用，以求得问题的解，这样的系统称为产生式系统。（2分） 产生式系统一般由三个基本部分组成：规则库、综合数据库和推理机。（3分） 6．产生式系统中，推理机的推理方式有哪几种？请分别解释说明。（5分）答：产生式系统推理机的推理方式有正向推理、反向推理和双向推理三种。 正向推理：正向推理是从己知事实出发，通过规则库求得结果。 反向推理：反向推理是从目标出发，反向使用规则，求证已知的事实。 双向推理：双向推理是既自顶向下又自底向上的推理。推理从两个方向进行， 直至在某个中间界面上两方向结果相符便成功结束；如两方衔接不上，则推理失败。
