     We are all busy talking about and using the Internet, but how many of us know the history of the

 Internet?

 computers were large and expensive. Computer networks (网络) didn't work well. If one computer in the

  networks broke down, then the whole network stopped. So a new network system (系统) had to be set

  up. It should be good enough to be used by many different computers. If part of the network was not

 working, information (信息) could be sent through another part. In this way computer network system

 would keep on working all the time.

     At first, the Internet was only used by the goverment (政府),but in the early 1970s, university (大学),

 made "Surfing" (浏览) the Internet more convenient (方便).
