During Pre reading the teacher can go around the classroom and discuss the questions with several students This discussion should be student centered and arouse students interest in working outside The teacher should also ask the students some questions and try to let them have a general knowledge of volcanoes 3 While doing Reading and Comprehending the teacher may first ask the students to read the text quickly to get the general idea of each paragraph After reading the passage carefully students are encouraged to answer some questions and discuss the text structure 4 To consolidate the contents of the reading passage the students should be required to retell the volcanologist s experiences in their own words at the end of the class EmotionEmotion attitudeattitude andand valuevalue 1

power of nature and talk about them Sample expressions What happened in the pictures above Do you know any other natural disasters Please work with your partners and make a list of natural disasters such as earthquake snowstorm flood drought Have you ever seen a volcano Some new words lava erupt eruption crater active dormant extinct volcanoes 2 Warming up by reading the passage below SomeSome knowledgeknowledge aboutabout volcanoesvolcanoes There are thousands of volcanoes all over the world What makes volcanoes What happens The inside of the earth is very hot Because it is very very hot the rock has melted like ice It has become liquid like water It is always boiling like 用心 爱心 专心 6 water in a kettle If you have seen a kettle boiling you know that the steam and boiling water try to get out The very hot melted rock inside the earth also tries to get out Usually it cannot because the outside of the earth is too thick and strong But in some places the outside of the earth is thin and weak Sometimes a crack a small opening appears The hot melted rock which we call lava pushes up through the crack and bursts through Steam and gas shoot up into the air and the hot melted lava pours out Big pieces of rock may be thrown high into the air After a while the volcano becomes quiet again The melted lava becomes hard Later the same thing happens again and again Each time more hot lava pours out on top of the cold lava and then becomes hard In this way a kind of mountain is built up with a hole down the middle Perhaps the volcano will then be quiet and no more lava will burst out Perhaps it will start again hundreds of years later Vesuvius is the name of a very famous volcano in Italy It first came to life many many years ago It was quiet for hundreds of years Then in the year 79 it suddenly burst A great cloud of smoke shot up into the sky with great burning rocks which fell all around Hot lava poured down its sides About 3000 people were killed StepStep 2 2 PrePre readingreading 1 Can you imagine climbing into a live volcano in order to measure the temperature of the boiling rock inside Now read the following passage please WhyWhy doesdoes TazieffTazieff riskrisk hishis lifelife likelike this this Haroun Tazieff the polish scientist has spent his lifetime studying active volcanoes and deep caves in all parts of the world In 1948 he went to Lake Kivu in the Congo to observe a new volcano which he later named Kituro Tazieff was able to set up his camp very closed to the volcanoes while it was erupting violently Though he managed to take a number of brilliant photographs he could not stay near the volcanoes for very long He noticed that a river of liquid rock was coming towards him It threatened to surround him completely But Tazieff managed to escape just in time he waited until the volcanoes became quiet and he was able to return two days later This time he managed to climb into the mouth of Kituro so that he could take photographs and measure temperatures Tazieff has often risked his life in this way He has been able to tell us more about active volcanoes than any man alive 2 Encourage students to talk more about volcanoes by looking at the following pictures 用心 爱心 专心 7 StepStep 3 3 ReadingReading andand comprehendingcomprehending 1 Fast reading Ask students to skim the passage so as to get the key words and general idea of each paragraph and answer the question What s the main idea of the text 2 Read the passage carefully and answer the following questions 1 Why is a volcanologist s job important 2 Why is the lava that flows on Mount Kilauea more dangerous than the actual eruption 3 Why was it difficult for the writer to walk towards the edge of the crater 4 What does the writer find impressive about volcanoes even after studying them for many years 5 What did the author think it was when an eruption occurred 6 Why did the scientists look like spacemen Suggested answers 1 This passage is a first person account of a volcanologist s experiences The volcanologist described his exciting job and wrote down his first sight of an eruption 2 1 Volcanologists study volcanoes so that they can warn people when the volcano is going to erupt and so save many lives 2 The lava flows down the mountain and can cover up or burn villages in its path The rocks that erupt from the volcano usually don t damage anything because no one lives near the crater 3 The author was wearing special protective clothing that made it difficult to walk 4 The author finds their beauty and their potential to cause great damage very impressive 5 He thought it was an earthquake 6 Because they wore white protective suits that covered their whole body 3 Ask students to scan for detailed information and discuss the following question with their partners and be prepared to report to the class Question Having learned a little more about the work of a volcanologist do you think it is an occupation you would enjoy Give you reasons Suggested answers No I probably wouldn t enjoy this job because I wouldn t have to live in other countries and I don t like being in dangerous situations either Above all I m not very good at science OR Yes I d love to do a job like this because I would enjoy working outside and I think I would enjoy the adventure It would be exciting to meet people from different countries and I would feel good about helping people avoid danger 用心 爱心 专心 8 StepStep 4 4 LanguageLanguage studystudy Dealing with any language problem if any words or sentences students might not understand to help
