2、pics for students to discuss, letting students get some more knowledge about the power of nature.Pre-reading provides some questions and a questionnaire to help students focus on the topic of the reading passage and lead the students to think about any personal experiences of working outside, such a
3、s things about climbing into a live volcano, doing dangerous work, travelling, taking risks, adventure, studying rocks and so on.Reading is a first-person account of a volcanologists experiences. He loves his job very much because he can help protect ordinary people from one of the most powerful for
4、ces on earth. His job is collecting information for a database about Mount Kilauea and helping other scientists to predict where lava from the volcano will flow next and how fast. Once, he watched an eruption and then collected some lava for later study. After many years, he is still enthusiastic ab
5、out his job. Reading contains a picture that is an absolutely fantastic sight. After a glance at the title of the text and the headlines within it we know that it is an account, in which there are many emotion expressions.

While doing Warming Up the teacher can lead in the topic of this unit by showing students some pictures of natural d
10、isasters and introducing some technical vocabulary concerning volcanoes to review and develop students1 understanding of what a volcano is.To ask students to consider other natural disasters and the ways humans deal with them.2. During Pre-reading the teacher can go around the classroom and discuss
11、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.

14、 ability.2. To enable the students to talk about natural forces. 四、教学过程Step 1 Warming up1. Warming up by looking and talkingShow the following pictures to the students and let them know about the power of nature and talk about them.Sample expressions:What happened in the pictures above? Do you know
15、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.Some
16、knowledge about volcanoesThere 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.lt has become liquid, like water.lt is always boiling, like water in a kettle.If you have see
17、n 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 sm
18、all 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 become
19、s 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 aga
20、in hundreds of years later.Vesuvius is the name of a very famous volcano in Italy.lt 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 p
21、oured down its sides.About 3000 people were killed.Step 2 Pre-reading1 .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.Why does Tazieff risk his life like this?Haroun Tazieff, the polish scientist, h
22、as 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 manag
23、ed 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
24、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 m
25、ore about volcanoes by looking at the following pictures.Step 3 Reading and comprehending1.

Read the passage carefully and answer t
26、he 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 st
27、udying 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 volcanologists experiences.The volcanologist described his exciting job and wrote down his first sigh
28、t of an eruption.2. (l)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 dont damage anything because no
29、 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
30、 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.Sugg
31、ested answers:No, I probably wouldn*t enjoy this job because I wouldnt have to live in other countries and I dont like being in dangerous situations, either.Above all, Im not very good at science.ORYes, rd love to do a job like this because I would enjoy working outside and I think I would enjoy the
32、 adventure.lt would be exciting to meet people from different countries and I would feel good about helping people avoid danger.Step 4 Language studyDealing with any language problem if any(words or sentences students might not understand)to help the students to have a better understanding of the te
