THE INTERNETThe Internet is the most significant progress in the field of communications. Imagine a book that never ends, a library with a million floors, or imagine a research project with thousands of scientists working around the clock forever. This is the magic of the Internet. Yet the Internet has the potential for good and bad. One can find well-organized, information-rich websites. At the same time, one can also find wasteful websites. Most websites are known as different Internet applications. These include online games, chat rooms and so on. These applications have great power too. Sometimes the power can be so great that young people may easily become victims to their attraction. So we need to recognize the seriousness of the problem. We must work together to use its power for better ends.
