Computer networks(网络) didn’t work well. If one computer in the network 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 could be sent through another part. In this way the computer network system would keep on working all the time.At first, the Internet was only used by the government, but, in the early 1970s, universities,hospitals and banks were allowed to use it too. However, computers were still expensive and the Internet was difficult to use. By the start of the 1990s,computers become cheaper and easier to use. Scientists had also developed software(软件) that made “surfing(浏览)” the Internet more convenient(方便).Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popularamong students. The Internet has now become one of the most important parts of people’s life.( )1.The Internet has a history of________years.A.about 40B.less than 30C.more than 45D.nearly 35( )2.Scientists set up a new network system to________.A.make the computer cheaperB.make the system work wellC.make the computer go wellD.develop new softwares ( )3.The Internet was widely used in the________.A.1960sB.1970sC.1980sD.1990s ( )4.The underlined words “get on-line” in Chinese mean________.
