| Many people like to surf on the Internet. Exploring the Internet is one of the most important activities of the day. The Internet brings the outside world closer to people's homes. Some people say the world is smaller than before because of the Internet. What's going on in other countries? How do people live in other countries? Is there a good game somewhere? What's the life in the deepest part of the sea? If you want to answer all these questions, you can also come to the Internet. Of course, people can also learn through read- ing books, listening to the radio or watching TV. But by the Internet they can learn better and more easily. A lot of information can be collected at a great speed. Can we go shopping without leaving home? Can we see a doctor without going to the hospital? Can we study without going to the school? Can we draw money without going to a bank? All these things seemed to be impossible in the past, but now they have become the truth. The Internet helps us open our eyes. The Internet also helps us open our minds. The Internet often gives us new ideas. In a word, it helps us in many ways. Great changes have taken place in our life since the use of the Internet. | ||||||||
