高考英语一轮复习Unit5Thepowerofnature学案新人教版选修6大自然的力量晨读·经历A Volcano EruptionAs the best candidate,I was appointed to collect and evaluate information for a database about diverse natural disasters, such as hurricanes, typhoons or thunderstorms. Sometimes I did this by giving out questionnaires to those who went through them. But sometimes I had to go through actual disasters myself. The Musaki Volcano was one of them.At that time, I lived in a bungalow alongside the volcano with a novelist, who came for the appreciation of its eruption. One day, when I was drawing diagrams on the balcony and he was bathing inside, the volcano erupted unexpectedly. The ash and lava fountains shooting highly in the sky varied from 50 to 100 meters in height. It was absolutely fantastic! I even noticed a rainbow appear in the fog caused by a heat wave.But, glancing through our surroundings, I foresaw the potential danger and found no guarantee of our safety. The uncomfortable gas almost made us unconscious. Sweats of anxiety began to drop. Managing to stop panicking and trembling, we quickly put on our protective suits, helmets and boots and eventually made our way to a safe place. How lucky we were even though my precious equipment and documents were all burnt to the ground!火山爆发作为最好的候选人，我被委派为一个数据库收集和评估各种自然灾难的信息，例如飓风、台风或雷暴等。

Find something about volcano.Volcano is one of these natural disasters. We should also do something to avoid its eruption or reduce its damage to us.What do you know about volcanoes?How is a volcano formed?How does a volcano erupt?5.
