Have you ever been out on a sunny day without an umbrella when suddenly it starts to rain? Who changed tile weather? Certainly not the weather man.Nor the weather report of your town.It is the sun!

    When the sun rises,it is day.When the sun sets.it is night.Again,days are warmer than nights.This is because the sunshine falls on the earth during the day.The sunshine makes the land,the water and the air warm.At night when the sun is not there,it is cooler.In the mornings and in the evenings the sunshine is slanting.So it is not very hot.At noon the sunshine falls straight on the earth,and it is very hot.

    We know that the earth goes round the sun.When one half of the earth is close to the sun,the other half is away from it.The part of the earth closer to the sun has summer.Here the days are warmer and longer.And the part of the earth away from the sun has winter.Here the days are cooler and shorter.For example,when it’s winter in China,it is summer in Australia.So you see,the temperature and the length of the days are decided by the sun.

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.
