题目内容

I am a computer expert. I have been in the field for only a short time. I never learned much in the way of science or math. And I am quite puzzled by things like engineering or electronics.Then why am I able to write about computers I can write on this subject because of these shortcomings. The last two years of learning has been a hard test for me. By hard work I have managed to learn enough to use computers fairly well, and to work with people who know a great deal more than I. Since I have learned all this at such personal cost, I would like to share my know-ledge with others. More and more people want to know about computers, and want to know quickly.The best way to learn is to take a course. However, many people do not have the time for this. They will have to find some other ways to get some basic information. I hope to be able to help them by writing about some of the things I have learned by myself.I have a home computer on which I’ve learned in my own time. I have used it like a home study course. I have sat down with it day after day, night after night. I have forced it to give up some of its secrets. Now I can use it to do some of the work that I get paid for. And I can do this work in my own home, instead of in an office. Many people may soon be working in a computer at home, just as many now take in other people’s typing.Some things about computers are easier than you may fear. First, computers are logical. Things that at first seem difficult will make sense to you after you learn the rules. Second, it is really not hard to learn enough to use today’s machines. You do not need to be a great brain. But you do have to learn to think in new ways. And you do have to keep a good bit of information in your head. Finally, there are many people around who are really enthusiastic (热心的) about computers. These people are always happy to be of help. According to the passage, a computer can be used to help you()

A. take special courses in science
B. take in other people’s typing
C. get other people’s secrets
D. do your work at home

Science fiction has a tendency to become science fact. Something like Hal, the on-board spaceship computer capable of ethical decision making and intelligence in Arthur Clarke’s 2001:A space Odyssey , is being discussed seriously in modern artificial-intelligence (AI) laboratories. (46) That is not to say that computers will evolve exactly as Clarke envisioned, any more than propulsion systems developed in the way Jules Verne imagined three-quarters of a century before a rocked sent a spaceship to the moon. (47)However, computer scientists are developing systems that come very close to mimicking parts of human cognition;it seems plausible that something like Hal will be around before you depart from this earth.(48) Computerized cognition, or artificial intelligence (AI), as it is often called, is broadly defined as that branch of computer science that deals with the development of computers (hardware) and computer programs (software) that emulate human cognitive functions. Cognition involves perception, memory, thinking, language processing and many other related functions which are carried out in a more or less exact way. You can, for example, see and recognize your friend’s face; compose a sensible poem set in iambic pentameter; mentally calculate the most direct route from your home to the college, and distinguish sour milk from fresh milk. We do things like this every day with no effort. We also do a lot of foolish things, such as put shampoo on our toothbrush. We are human and that’s a problem for computers, being perfect machines that never make a mistake, "computer errors" notwithstanding.If a computer could simulate human thought and actions precisely, then it would be as good as we are in doing the list of things mentioned earlier, but also be just as fallible as we are. (49)It is important to recognize the distinction between those who want to write programs that will perform human tasks well, such as the program we are presently using that draws a squiggly red line under misspelled words and those who aim to clone human thought. Computers and their impressive programs have become such an indispensable part of our everyday life that we wonder how we got along without them—still, they aren’t clever enough to shampoo with toothpaste.When we discuss AI, it is usually intertwined with Cognitive psychology and neuroscience. (50) Ideas from one field, for example, neuroscience, might be incorporated into another, for example, artificial intelligence, and yet other ideas from cognitive psychology might be applied to both other areas. All three—AI, cognitive psychology, and neuroscience (especially neuroscience)— build a platform for cognitive science. Ideas from one field, for example, neuroscience, might be incorporated into another, for example, artificial intelligence, and yet other ideas from cognitive psychology might be applied to both other areas.
