Man and Computer
What makes people different from computer programs？ What is the missing element that our theories don't yet【51】for？ The answer is simple: People read newspaper stories【52】a reason to learn more about what they are interested in. Computers, on the other hand, don't. In fact, computers don't【53】have interests; there is nothing in particular that they are trying to find out when they read. If a computer【54】is to be a model of story understanding, it should also read for a "purpose".
Of course, people have several goals that do not make【55】to attribute to computers. One might read a restaurant guide in order to satisfy hunger or entertainment goals, or to【56】a good place to go for a business lunch. Computers do not【57】, and computers do not have business lunches.
However, these physiological and social goals give【58】to several intellectual or cognitive(认知的)goals. A goal to satisfy hunger gives rise to goals to find【59】about the name of a restaurant which serves the desired type of food, how expensive the restaurant is, the【60】of the restaurant, etc. These are goals to【61】information or knowledge, what we are calling【62】goals. These goals can be held by computers too a computer might "want" to find out the location of a restaurant, and read a guide in order to do so【63】the same way as a person might. While such a goal would not【64】out of hunger in the case of the computer, it might【65】rise out of the "goal" to learn more about restaurants.
