Most publishing is now "electronic" in
the sense that books, magazines and newspapers are prepared on computers, and
exist as computer files before they are printed on paper. Often there are
advantages to give readers access to the electronic versions of publications as
well as--or even instead of--the printed versions. Print publications have lots of advantages. Paper is pleasant to handle, easy to read, and very portable: you can read it almost anywhere. On the other hand, print has its weaknesses. Paper is expensive, and articles are often cut to fit the space available, printing and distributing paper is expensive and takes time. Printed materials are expensive to store and almost impossible to search. Electronic publishing offers solutions to all these problems. Suppose a publisher makes the electronic copy of a A. Readers will have more accesses. B. Books and newspapers will be kept as computer files. C. It will not make any sense to keep the printed versions. D. Electronic publications will replace printed ones. [判断题]控制幅度原则是一个上级直接领导与指挥下属的人数应该有一定的控制限度,并且应该是有效的。

The clubs are for people who have some computer knowledge already.
