     Mails, games, music, news, chat rooms and shopping! The Internet is part of the way we live today. It's

easy to get onto the Internet. The only thing we need to do is to use a modem (猫) which is used for connecting

a computer to a telephone line. The Internet is changing and growing all the time. More and more people have

computers and use the Internet. Using the Internet means surfing the World Wide Web (That's the "www" you

always hear about). The Web (网) has large numbers of websites (网站) in it. They are the places you go to get

information and do things. 

     Where do these websites come from? They are made by web designers. What happens when you click on a

word or a picture? You are sent to another page. It's all because of the web designer. Web designers do a lot of

work by using a computer programming language.

     Is Web design all about computer programming? No. It's about making something new. Web designers must

imagine a lot when they are making a website. It must look good and be fun to use. A big part of Web design is

art. They choose the best pictures and colors to make the website look good. They also write the things that you

see on the website. An important part of their job is to share ideas with the website manager about how to design

the website well.
