telephone calls every day, we shouldn't forget the great inventor Alexander Graham Bell. Today, we'll learn something more about him.

Show the following.

1. What do you know about the inventor?

2. How useful is his invention to human society? Why?

After a few minutes.

T: Now, who'd like to show your answers?

S1: Let me try. I know Alexander Graham Bell was born in Scotland and he was very curious about the world around him when very young. He did many tests to improve what he had invented and he had made many other inventions in his life. As we all know, it is very convenient for people to communicate with each other through telephones. It is certainly true that telephones have become part of our everyday life. Living in this "information age", we cannot bear a world without the ringing of phones almost anywhere we go.

S2: I think Bell was a very great inventor. He deeply loved his mother who was almost deaf and was determined to do something for the disabled to live a better life. What a great son! I think he was also hardworking because he took a lot of trouble doing many experiments to solve the problems and invented a lot of things. I can't imagine what the life would be like without telephones. Maybe we will live in a silent world without knowing of the things around us, which is unbearable for us human beings in modern society. And it becomes more and more important to use telephones to receive and send information with the development of modern IT.

...
