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

      Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks 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 computer network system would keep on working all the time.

At first the Internet was only used by the government(政府),but in the early 1970s,universities.hospitals and banks were allowed(允许)to use it too.However,computers were still very expensive and the Internet was difficult to use.By the start of the 1990s,computers became cheaper and easier to use.Scientists had also developed software(软件)that made “surfing” 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 popular among students.

      The Internet has now become one of the most important parts of people's life.

During the day we work and play and at night we sleep. Our bodies rest while we sleep. In the morning we are ready to work and play again. It is while we are asleep that our bodies grow most. When children feel tired and angry, they usually need more sleep. We can get our lessons better, and we feel better, too, when we have had plenty of rest. Boys and girls, eight or nine years old, need ten hours of sleep every night. Our bodies need plenty of air when we sleep. If we do not get enough fresh air we wake up feeling tired. While in bed we must not cover our heads. If we do, our lungs (肺) will not get enough fresh air. If we open our windows at night we can have plenty of fresh air. Cool air is better than warm air. Boys and girls must get plenty of sleep if they want to grow and be strong.
