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(建立) 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.

Have you ever beard of Iceland? Iceland is a country, one-tenth of which is covered with ice. However, it is said that Iceland is the land of heat. Smoking volcanoes (火山), white steam (蒸汽) and hot springs are more amazing than the other sights including ice there.

    It has taken millions of years for volcanoes and lava flows (熔岩流) to build Iceland. When hiking through one of Iceland’s many ancient lava fields, you may notice something strange. White steam is rising from each vent in front of you. Iceland is covered with vents which steam can pass out of. The steam comes from naturally heated rocks and hot water below the Earth’s surface (表面).

    Like steam vents, hot springs can be seen here and there in the ancient lava fields. Blue Lake is the most famous hot spring in Iceland. It isn’t far from the capital city of the country. The water and white earth in it can make your skin as soft as a newborn baby’s skin. Enjoy that water, because it has traveled a long way. It starts nearly two kilometers under Blue Lake. There, water from the ocean continues moving up slowly into the spaces between hot rocks below the surface. And then the water is heated by hot rocks. Powerful machines and long pipes (水管) help bring the heated water to the surface. People in Iceland use natural hot water for hot springs. Besides, they use it to create electricity that can be used to heat homes and even greenhouses.

    Iceland is one of the few places on the Earth where active volcanoes lie below ice. Heat from the volcanoes creates a strange and wild beauty. Therefore, some people believe that it’s better to call the country “Heatland” instead of Iceland. If you have a chance to travel there, take it.
