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 business people also wanted to use the Internet to send and receive messages. For some years, people could only send very simple text. They could not send photos or documents by the Internet. 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. allow sb to do sth 允许某人做某事 各种各样种类的 接收,收到 1924 Britain John Logie Baird Complete the sentences with the words in the box. direction introduction spread trade Before the _ of printing, few people could read.
