答案 Computer Computers are counting machines, as they are called. Computers can do simple computations-- add, subtract, multiply and divide quickly and accurately. Even the most skillful mathematician could not begin to perform simple arithmetical computations as rapidly and as accurately as a computer can. With the development of science and technology computers will find wider and wider applications. For example, computers are being used in space travel, in aviation, in medicine, in education, in industry, in agriculture, in design, etc. Not only can the computer gather facts, it can also store them as fast as they are gathered and can pour them out whenever they are needed. Not even computers can predict the future, but the benefits of computers are becoming more obvious every day. One thing that we have to remember is that computers only do what they are told to do not what we want them to do. Even though they are taking over some of the tasks that were once accomplished by our own brains, computers are not replacing us--at least not yet, for they are incapable of independent thinking. How we use them is for us, not the computer, to decide.
