Teaching procedure:

Step 1: In weaker classes, students probably will not know what some of　the words in Part A mean. Write the words on the blackboard and help them finish the part. e.g.: What’s the use of a camera/battery/hand/wheel/speaker?

A camera takes pictures.

A battery gives us power.

A hand helps pick up things.

Wheels help things move.

　We can hear sound through a speaker.

Step 2: Show students robot pictures and ask students what other features　a robot might have. This will help students with Part B. Encourage students to use their imagination.

①　Ask students to look at the picture on page 24 and answer the questions.

②　Ask students questions according to the pictures shown:

　　　 What does it look like?

　　　 What is there on the head/in the face/on both sides of its body?

　　　 How does it speak?

　What is the use of the arms/hands?

　　　 How does it move?

　　　 What kind of energy does it have?

　Step 3: Explain the context of part b. Daniel is writing an article to describe his ideal robot. Have students work in pairs and complete the

exercise.

Step 4: Ask volunteers to read the completed article for the class. Check for mistakes and mispronunciations.
