    题目列表(包括答案和解析)

    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.

    　　We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.
    　　Global positioning system (GPS) (全球定位系统)
    　　It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers.
    　　Space Technology
    　　Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space.
    Underwater Robot
    Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.
    The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.
