Tapescript
After printing was invented, knowledge was spread around the world by books. For many years, books were very expensive. Each one was written by hand, so very few books were produced. Today, books are produced quickly. They’re light, cheap and easy to get hold of.
But the early books are now too valuable to be picked up and held in the hand, so here in the British Library, they were copied onto a computer a few years ago. Have a look at the screen here. You can turn the pages on the screen, without touching the real books.
1 Why were so few books produced in ancient times
2 Why were many old books copied onto a computer
Listen again and answer the questions.
Because they were written by hand.
They are too valuable to be picked up and held in the hand.

3 How has the computer helped people read old books in
the British Library
Old books were copied onto a computer a few years ago for people to be able to read them without touching them.
Read the passage and choose the best title.

The World Wide Web
The Internet and the Web
The future of the Internet

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.
It was that...强调句型
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.
发送和接收信息
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.
例如
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.
数百；成百上千；许许多多…
The Web also makes people's lives easier because now many things can be done from home, twenty-four hours a day. 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.
Now complete the chart.

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. 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.
