Now many people are talking about and using the Internet. But not all of us know the history of the Internet. In fact, scientists began to study the Internet in the 1960s. However, it didn’t work well enough. For example, if one computer in the network (网络) broke down, then the whole network stopped. Scientists kept trying. They set up (建立) a new network system (系统). Many different computers could use it. Even (即使) a computer didn’t work, the whole system would be OK.

At first only government (政府) used the Internet. But in the early 1970s, universities (大学), hospitals and banks (银行) began to use it, too. But it was still very expensive and difficult to use. Then in the 1990s, computers became cheaper and easier to use because of scientists’ hard work.

Now the Internet comes into every part of our life. It’s hard to believe what our life will be like without the Internet.
