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)。

Unit 3 ComputersMost kids have cellphones or tablets (平板)and are texting or using social media all thetime. Experts say that parents should use appsto watch out for their children's onlineactivity.According to a survey, 70 percent of U．S.teens carry cellphones, and Russ Warner, the CEOof Net Nanny, is in the business of protectingkids online. His best advice to parents is toknow what is out there and to plan in advance.“Put a plan into place because kids like tofeel protected，” Warner said. “They like tofeel like Mom or Dad is helping.”According to another study, almost 90percent of children have seen cyber bullying (网络欺凌) in the last year. However, Warner saidonly 50 percent of parents talk with kids aboutavoiding these experiences.“That means the other half don't and that'sa problem，” he said.Warner often speaks to parent groups concerned about keeping their teens safe, “Oftentimes (时常地) if we can't control or wedon't understand something, we avoid it and wecan't do that anymore.”He said parents need to talk to theirchildren about online danger, and then they needto use safety software.
