Step I Listening

The students will listen to the volcanologists talk about their most frightening experience. First get the students to describe the three pictures to help them recall the words or expressions they've learned about the occupation - volcanologist. Then listen and write their names under the pictures.

T: Do you still remember the work of a volcanologist?

Ss: Yes. He collects information about a volcano to help predict volcano's eruption.

T: How can they get the information?

S1: They must climb into a live volcano to take the temperature of the boiling rock inside and collect some lava for later study.

T: Excellent! Please turn to page 38. Describe the three pictures with your partners. We'll ask some of you to describe the pictures in class.

The students work in pairs to describe the pictures. They can turn to the text if they have some difficulty.

T: Who will describe Picture 1?
