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 repair 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.

Dr.Teruo Higa was born on December 28, 1941 on Okinawa and grew up there. He studied agriculture and took his doctorate from the Agricultural Research Department of Kyushu University Graduate School. He became a lecturer in 1970 and has been professor of horticulture since 1982.
Dr.Higa is famous for creating EM technology.He created EM technology in order to address the problem of excess wastes and bad farming techniques in the present-day world. EM stands for effective microorganisms. It is a multi-culture of coexisting anaerobic and aerobic microorganisms. Microorganisms are the smallest complete units of life. They can exist independent of a bigger organism. Bacteria are considered microorganisms. They are constantly at work, some helping bigger organisms,and others bringing decay and bad health. These opposing processes of constructive and destructive forces are always ongoing, creating a balance. If the balance tips towards the destructive side, the host organism grows ill. lf it tips towards the constructive side, the organism experiences good health.
These organisms can be used in farming to create a good growing environment for all kinds of crops and animals. The process involves collecting human and animal waste products such as kitchen garbage and manure. This is then sealed into a barrel along with a certain amount of EM powder. The microorganisms then turn the waste into mulch, which acts as a great source of nutrients for crops and animals. Rice paddies that are treated with EM produce harvests that are much bigger than those of conventional farms. Moreover, EM rice paddies require less tilling and weeding than other paddies.
Dr.Teruo Higa's ideas have caught on around the world. One of his biggest successes was in North Korea, where his technology was used to create a record-breaking crop yield. EM helped many crops, such as corn, Welsh onions and Chinese cabbages in North Korea. For the impoverished nation, this was a godsend.
