module9 unit 2 ■Warm up by getting to know about computers. Hello, class. You know how to use a computer. But do you know what a computer is? A computer is a machine that stores Information in its memory, and does automated calculations on that knowledge. Automated calculation means that if the machine is given some input, it will produce some output. This can be used to do many things, from playing games, to solving very hard math. This allows people to use computers to do jobs, or just to have fun. ■ Read and underline. On page 28 is an article about books and computers. Now let’s go on to read it. While reading, try to: cut/ the sentence into thought groups, study the predicative, darken the connectives and underline all the useful expressions.

Every night, I look at the photos of David Beckham and Yao Ming before I go to sleep. Can we imagine life without paper or print?Paper was first made, about 2,000 years ago, from silk, cotton, bamboo and wood. People then learned to make a book. And people began to read books.Then Chinese invented printing. When printing became popular at the beginning of the 11th century, books could be produced so quickly and cheaply that more people learned to read. Then came the Internet in the 20th century.
