I Like the Internet

The Internet is very important in the life．It is very useful．I often use the Internet to find some information．I can learn English and practice my spoken English．I can see movies and download music．I can send e-mails and have a chat with my friends．I can do some shopping online．The Internet makes my life colorful．I like the Interact very much．
