      The World Wide Web has been the most popular development of the Internet．The Web is like a big electronic book with millions of pages．These pages are called homepages．
     You can find information about almost anything in the world on these pages．For example，you can use the Internet instead of a library to find information for your homework．You can also find information about your favourite sport or film star，talk to your friends or even do some shopping on the pages．Most pages have words，pictures and even sound or music．
  What is email？
      Electronic mail （Email） is a way of sending messages to other people．It's much quicker and cheaper than sending a letter．
      If you want to use email，you must have an email address．This address must have letters and dots and an "@" （meaning "at"）．This is what an address looks like：email@star．net．Write a message，type in the person's email address，and then send the message across the Internet．People don't need to use stamps，envelopes or go to the post office since the invention of the Internet．Quick，easy and interesting，that's the Internet!
