Share some of the reports. 3. Introduce the listening text on page 58. One possible version: We all believe that androids do not have their own feelings, but as we can see in some movies, many people imagine that androids can think as human beings do. Suppose it is true, do you think they like to serve human beings or not? What do they hope we human beings to treat them? Now we are going to listen to a dialogue between Sally and Brenda, two androids, and see how they say. In this dialogue, you may come to some new words, but just forget them, and focus on getting your answers. 4. Page 58 listening, listen for twice. One student writes down the answers to “about their jobs”, “about changing their jobs” and “about who decides their future”; the other writes down the answers to “about how they are different from people” and “about how they are the same as people”.

5. Ex-change the answers in groups. 6. Let students have the correct answers.
