Let’s do
The Internet has been around for many years, but it was the invention of the World Wide Web that made it really useful to people. Together，the Internet and the World Wide Web have changed the world.
The Internet was invented by the US government in the 1960s, for the army to use. In the 1970s，scientists and businesspeople also wanted to use the Internet to send and receive messages. For some years，people could only send very simple texts. They could not send photos or documents by the Internet.
Reading task
That changed in 1991，when a British scientist named Tim Berners- Lee invented the World Wide Web. The World Wide Web allows people to send various types of files, such as texts, photos and videos by the Internet, so more and more people started to use it in the 1990s.
Today，the Web has hundreds of millions of users. It has changed the way people live, work and play. Through the Internet，email allows us to communicate nearly instantly with people thousands of miles away. People and businesses use e commerce and online shopping to buy and sell things across the world. The Web also makes people's lives easier because now many things can be done from home，twenty-four hours a day.
Reading task
The Web can help you do research for your homework, so that you do not need to go to the library. You can use Internet banking, instead of going to the bank. And，of course，people just“ surf the Web” when they want to relax.
Technology changes quickly，and it is hard to imagine what the future of the Internet and the Web will be. But it seems impossible to imagine life without them.
Reading task
Now complete the chart.
The Internet was invented for the army to use.
Scientists and businesspeople wanted to use the Internet to send and receive messages.
The World Wide Web was invented.
More and more people started to use the Internet to send various types of files.
The Web has hundreds of millions of users. It has changed the way people live, work and play.

E-books
Just as email has changed the way we write to each other, e-books are changing the way we read. We can easily download new e-books from the Internet. It is much easier and quicker to search for passages now, and we can also write notes in an e-book.
Reading task
What is more, they save a lot of paper. But e-book readers are still more expensive than paper books, so not all people can afford them. However, with the rapid development of electronic technology, reading e-books will become cheaper and cheaper. A lot of people think there will be more e-books than paper books in the near future.
