Unit 3 Computers【导语】万维网的出现彻底改变了世界，创造了大量的财富并从根本上改变了人们的生活方式。
而它的创始人英国计算机科学家蒂姆·伯纳斯·李对于自己这一成果的现状并不满意。
一起去了解一下这位“万维网之父”吧！Most people have never heard of Tim Berners－Lee.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 well－known word.Berners－Lee，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 Berners－Lee to Johann Gutenberg，who invented printing by movable type(活字)in the fifteenth century.Berners－Lee was born in England in 1955.His parents，who helped design the world's first commercially available computer，gave him a great love of mathematics and learning.In 1980，Berners－Lee 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 of things he couldn't remember.He invented a software programme 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，Berners－Lee 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.【词海拾贝】1．creator n．创造者2．commercially adv.商业地3．track n．轨道4．software n．软件5．passive adj.被动的；消极的【问题思考】阅读短文，判断正(T)误(F)。

And 160 researchers join in the project. The university's researchers made an agreement with the European Commission. The work may try to make “multi－modal interfaces (界面)”which allow machines to sense and respond to the moods of the user.Programme coordinator (协调者) Professor Roddy Cowie said while itsounded like science fiction，computers which responded to human feelings would appear.“At the moment，our use of computers is limited by the fact that we need a keyboard and a screen to access(使用) them，”he sa id.“But feelings are part of normal speech, and experience has shown that most users are deeply uncomfortable with speech interfaces that ignore them－too uncomfortable to use them very much.”“If we can make computers more expressive, and also less challenging to use，there is a great chance to let people make full use of information technology.”The emotion－sensitive computer would have its own “personality” and build a social relationship with the user.“It's a fair bet that in 30 years' time, emotion－sensitive interfaces will be as much part of life as windows and mouse interfaces are now，”said Professor Cowie.The project team believes such computers would play an important part in teaching and learning.1．What does the passage mainly tell us?A．Researchers at Queen's University have completed a project.B．The research for an emotion－sensitive computer is being led by a Northern Ireland team.C．160 researchers have joined in the 10 million－euro project for a thinking computer.D．Computers are playing a more and more important part in our daily life.2．It can be learned from the passage that ________．A．an emotion－sensitive computer has been invented and is being put into use B．an emotion－sensitive computer cannot respond to the moods of the userC．an emotion－sensitive computer has not been invented by the teamD．the research for an emotion－sensitive computer has not gained people's support3．What does Professor Roddy Cowie think of the emotion－sensitive computer?A．He thinks it is only a part of science fiction.B．He thinks it is worth the research and it is easy to produce.C．He believes it is impossible for the team to invent the emotion－sensitive computer.D．He believes it can come into being.4．In Professor Roddy Cowie's opinion，________ limits our use of computers.A．the fact that a keyboard and a screen are needed to use computersB．the fact that we don't know much about computersC．the fact that feelings are part of normal speechD．the fact that the emotion－sensitive computer has its ow n “personality”5．What are emotion－sensitive computers believed to do in the future?A．They will take the place of teachers in teaching and learning.B．They can build a social relationship with human beings.C．They will replace human beings and control the world.D．They will have the same“personality”as their users.Ⅳ.翻译句子1．随着春天的到来，万物复苏了。
