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 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, but in the early 1970s. universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of 1990s, computers became cheaper and easier to use. Scientists had also developed software that made "surfing" the Internet easier. 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 young people. The Internet has now become one of the most important parts of people's life.

What does blood do for us? It brings food to all parts of our bodies and takes waste away from them. All parts of our bodies are made of cells. These cells are very small. They all need all the time. No one could make pictures of cells because no one could see them.

What makes the blood move round the body? The heart is a pump. It pumps the blood and sends it round the body. The heart has rooms with doors between them. It pumps blood in and out through these doors by changing the size of the rooms so that the doors are opened and shut. The heart keeps a stream of blood going all around the body and back again to itself. The heart is a very important part of one's body. When it stops beating, one will die.
