What ways do you think the computer can help us?2Who do you think is the founder of the World Wide Web? Please read the following passage to get the answer.Most people have never heard of Tim BernersLee. He is not nearly as rich or famous as Marc Andreessen, who is the founder of Netscape, or Bill Gates, whose name has become a wellknown word.BernersLee, who works in a small office at the Massachusetts Institute of Technology, is the creator of the World Wide Web. The creation of the Web is so important that some people compare BernersLee to Johann Gutenberg, who invented printing by movable type (活字) in the fifteenth century.BernersLee was born in England in 1955. His parents, who helped design the worlds first commercially (商业地) available computer, gave him a great love of mathematics and learning.In 1980, BernersLee went to work at CERN, a physics laboratory in Geneva, Switzerland, where he had a lot of material to learn quickly. He had a poor memory for facts and wanted to find a way to help him keep track (轨道) of things he couldnt remember. He invented a software program that allowed him to create a document that had links to other documents. He continued to develop his idea through the 1980s. He wanted to find a way to connect the knowledge and creativity of people all over the world.In 1991, his project became known as the World Wide Web. The number of Internet users started to grow quickly. However, BernersLee is not completely happy with the way the Web has developed. He thinks it has become a passive tool for so many people, not the tool for creativity that he had imagined.Warming Up1Look at the following picture.
