Like the computer, the Internet was among the greatest inventions of the twentieth century. The Internet has many advantages.
If you are connected to it, you will be part of the World Wide Web（万维网）. You can visit millions of websites and homepages. If you need information for a school project, you can find it on the Internet. If you want to listen to music and watch videos, you will find them on the Internet, too. Many people play computer games and chess on the Internet. What a lot of fun the Internet has brought us!
Another important thing about the Internet is e-mail. This enables you to keep in touch with your friends in different places. It is quicker and cheaper than regular（常规的）mail. You do not need envelopes.
Besides, you can use the Internet to do online shopping. You can buy all kinds of things on the Internet. For example, you can order food, books and CDs online. You can also book tickets for cinemas, theatres, and holidays.
In brief（简言之）, the Internet has made our lives more convenient and interesting.
