1990 was a significant year in world enents. In Febbruary, Nelson Mandela was set free after 27 years in prison. In October, East and West Germany became one country again. Then at the end of 1990, the World Wide Web was born. For this final event we have one man to thank, Tim Berners-Lee, the father of the Web.
Berners-Lee was born on June 8, 1955 in London, England. His parents, both computer designers, encouraged him to think and work creativelhy as he grew up. He was an excellent student and naturally took an interest in computers and science.
After graduating from Oxford University, Tim went to work at a science research centre in Sfwitzerland. There be developed some of the different systems that would later become the Web. The first was HTML, the computer language used to make web pages. The second was an address system that let  computers anhywhere find each other and send and receive information. In 1990, while still at the science centre in Switzerland, he put them together to make the first Internet browser. It could run on any computer and allowed people to create  share their information with the rest of the world.
Tim knew that the more people used the Web, the more useful it would be. He wasn’t interested in money but knowledge, so he gave out his invention for free to anyone who was interested. Many were interested and the growth of the Internet began.
Today Tim works as a professor at the MIT in America, researching new and interesting ways to use the Web. He has received many awards from governments and organizations for his efforts. He is still not very interested in money. That is why he is so admired by his students and workmates. It may also be one of the reasons that few people outside the world of technology know his name.

The most positive(乐观的) person I have ever seen is may dad! He is so positive that I do not  46  hearing a single word from him which is related(相关的) to hopelessness!
Unlike most mums and dads, my dad never says things that make me feel   47 . He is always there to give me encouragement and help.   48  I do wrong things, he always tells me what’s right in a positive way. For example, if I am in   49  , he often tells me to open the books he bought me. Then he asks me to read the   50  that can help me with the problems I’m facing.
