Show the pictures about the earthquakes. Ask the students where the two earthquakes happened, and discuss how serious the disaster brought to the people.

Step 2. Warming up

Warming up by learning vocabulary

　　Hello, everyone. We shall read about volcanoes today. Everyday disasters happen here and there. But how much do you know about them? Turn to page 93 and familiarize yourself with the words and expressions used in this unit. Try to make up a story based on the vocabulary, either in English or in Chinese.

Warming up by sharing opinions

　　The photo shows Mount St. Helens erupting on May 18,1980. What do you know about volcanoes?

　　A volcano is a place on earth where lava comes from the ground. Volcanoes often have the same shape as mountains. Most volcanoes have a crater at the top.

　　How volcanoes are made

　　Most volcanoes are made where tectonic plates come together. These plates move over each other, which causes magma to rise to the surface through weak places in the crust.

There are many volcanoes, live or dead, in the world. The next is a list of well-known volcanoes.
