I. Read the following statements and choose the correct answer. There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine (内燃机) has something to do with burning fuel, expanding gases and pistons (活塞) being driven. For people should have some basic idea of how the things that they use do what they do. Further, students might be helped by a course that considers the computer’s impact on society. But that is not what is meant by computer literacy. For computer literacy is not a form of literacy (读写能力); it is a trade skill that should not be taught as a liberal art. Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow should free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, and while our society needs some people who are experts at it, the same is true of auto repaid and violin-making. Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more “user-friendly”. Let us assume that in the future everyone is going to have to know how to use a computer to be a competent citizen. What does the phrase “learning to use a computer” mean? It sounds like “learning to drive a car”, that is, it sounds as if there is some set of definite skills that, once acquired, enable one to use a computer. In fact, “learning to use a computer” is much more like “learning to play a game”, but learning the rules of one game may not help you play a second game, whose rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished. 3. Learning to use a computer is getting easier all the time because ________.

A、A) programs are becoming less complicated

B、B) programs are designed to be convenient to users

C、C) programming is becoming easier and easier

D、D) programs are becoming readily available to computer users

Consider the following statements, made by the same man eight years apart. "Eventually, being &39;poor&39; won&39;t be as much a matter of living in a poor country as it will be a matter of having poor skills." That was Bill Gates talking in 1992. Way back then, the Microsoft chairman&39;s image was that of a rather harsh, libertarian-leaning fellow who proudly declared his products alone would "change the world." When asked what he would do with his billions, the boy wonder of Silicon Valley used to shrug off the question, saying his long workdays didn&39;t leave time for charity. But now listen to the same Gates—or perhaps not quite the same Gates—talking in the fall of 2000: "Whenever the computer industry has a panel about the digital divide and I&39;m on the panel, I always think, &39;OK, you want to send computers to Africa, what about food and electricity— those computers aren&39;t going to be that valuable... The mothers are going to walk right up to that computer and say: &39;My children are dying, what can you do？&39;"

Yes, even Bill Gates, the iconic capitalist of our day, seems to have come around. The self-assured Gates of 1992 was obviously a man of his times, confident of his industry&39;s ability to change the world, certain that the power of markets and new technology, once unleashed, would address most of the world&39;s ills. But the more skeptical Gates of the new millennium is someone who evinces a passion for giving and government aid. He shares a growing realization, even in the multibillionaire set, that something is amiss with the ideology that has prevailed since the end of the cold war: global-capitalism-as-panacea.
