【简答题】
阅读理解。 Many people like to search 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 places far away? Is there a good sports game somewhere? What's the life like in the deepest part of the sea? If you want to answer all these questions just come to the Internet. Of course people can also learn through reading or listening to the radio.
