Thomas Alva Edison2. Sally Fox3. Nose-top computer4. Nicolaus Otto5. Electric shoesTo learn more about inventions please turn to page 57 or look at the screen.Task 1: Looking and discussing.Look at page 57 or the screen. There are four pictures and four descriptions. Read the descriptions individually first and then match each picture with the correct description.Picture 1: Electric shoesPicture 2: Inflatable bicyclePicture 3: Edible chopsticksPicture 4: Nose-top computerTask 2: Discussing.Now discuss the following questions in pairs:1. Which of the four “invention” do you think would be more useful? Why?2. Is there anything you would like to invent? If so, what and why?Task 3: Listening and answering questions.1. Now we are going to listen to dialogue 1 on the tape, which is about Mr. Dean’s new invention. Listen carefully and try to understand it. Then you should answer the following questions:1) What are th e advantages of Mr. Dean’s new invention?2) How does it work?3) What can it be used for?4) Why does the patent officer not want to give the man a patent?2.
