第一部分：教学设Inventors and inventions

Period 3: Using Language Aims To help students read the passage ALEXANDER GRAHAM BELL To help students to use the language by reading, listening, speaking and writing Procedures I. Warming up by learning about Bell's Telephone Bell's Telephone A pioneer in the field of telecommunications, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland. He moved to Ontario, and then to the United States, settling in Boston, before beginning his career as an inventor. Throughout his life, Bell had been interested in the education of deaf people. This interest leads him to invent the microphone and, in 1876, his "electrical speech machine," which we now call a telephone. News of his invention quickly spread throughout the country, even throughout Europe. By 1878, Bell had set up the first telephone exchange in New Haven, Connecticut. By 1884, long distance connections were made between Boston, Massachusetts and New York City.

Bell imagined great uses for his telephone, like this model from the 1920s, but would he ever have imagined telephone lines being used to transmit video images? Since his death in 1922, the telecommunication industry has undergone an amazing revolution. Today, non-hearing people are able to use a special display telephone to communicate. Fiber optics are improving the quality and speed of data transmission. Actually, your ability to access this information relies upon telecommunications technology. Bell's "electrical speech machine" paved the way for the Information Superhighway.
