At the year of 1936, Alan Turing wrote a book to describe how computers could be made to work, and build a “universal machine “ to solve mathematical problem. With the development of information technology, in the 1960s, computers had new transistors and became smaller and smaller, then were connected to each other by the internet. As the years had gone by, computers were brought into peoples homes. Now computers have become the most important tools to connect people all over the world together. I was born in_in France. In_, I was built as an_,following instructions from cards with holes. In_, my real father, Alan Turing, described how computers could be made to work in a book and solved any mathematic problem by_ a _machine. People were surprised at my artificial_ . At first, I was the size of a large room. As times has gone by, I have been made smaller and smaller. In the_, I got new transistors. My memory became_ and_, but I got _and_, quicker and quicker. 16421822Analytical Machine1936buildinguniversalintelligence1960slargerlargerclevererclevererI could share information with others and talk to each other by a net.

With the help of the computer, we can deal with many things, such as listening to music, watching matches and sending e-mails.However, some students are so crazy about surfing the Internet that they get tired of study.Even some students break the law as a result of that. Personally, I am not quite against surfing the Internet in a way. But we should have a proper attitude towards the computer.Homework1.Review the text2. Finish Ex. 1/2 on Page 20.
