We are all busy talking about and using the Internet, but how many of us know about 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 (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 popular among students.

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

Bicycles in China

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to school, shops and anywhere else. Therefore(因此), China is known as “the kingdom of bicycles”. In China, many families have one or two bicycles.

Compared(与……比) with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles. Second, bicycles are small enough to park anywhere, while cars need a larger piece of land to park. What’s more, with lower speed, bicycles are safer than cars.

However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others’ safety. So they ride too fast. During rush hours, too many bicycles may cause traffic jams. We still have a long way to go to solve the problem.
