Comparisons were drawn between the development of television in the 20th century and the diffusion of printing in the 15th and 16th centuries. Yet much has happened 21. As was discussed before, it was not 22 the 19th century that the newspaper became the dominant pre-electronic 23, following in the wake of the pamphlet and the book and in the 24 of the periodical. It was during the same time that the communications revolution 25 up, beginning with transport, the railways and leading 26 through the telegraph, the telephone, radio and motion pictures 27 the 20th century world of the motor car and the airplane. Not everyone sees that process in 28. It is important to do so.

　　It is generally recognized, 29, that the introduction of the computer in the early 20th century, 30 by the invention of the integrated circuit during the 1960s, radically changed the process, 31 its impact on the media was not immediately 32. As time went by, computers became smaller and more powerful, and they became personal too, as well as 33 , with display becoming sharper and storage 34 increasing. They were thought of, like people, 35 generations, with the distance between generations much 36.

　　It was within the computer age that the term information society began to be widely used to describe the 37 within which we now live. The communications revolution has 38 both work and leisure and how we think and feel both about place and time, but there have been 39 views about its economic, political, social and cultural implications. Benefits have been weighed 40 harmful outcomes. And generalizations have proved difficult.

　　文章前几句的大概内容是说，人们总是把20世纪电视的发展与15世纪和16世纪印刷术的传播相比较。然而其间有很多的事情发生。直到19世纪，伴随着小册子、书籍以及期刊的兴起，报纸才成为前电子时代主要的媒体。

　　21.［A］根据句子前后逻辑关系和前一句时间状语的提示。between这里意思指20世纪与15世纪和16世纪之间。［B］before、［C］since和［D］later三项显然都不能全面表达这个意思。
