Scanning1. Scan the passage and answer the following questions:1) Why is a volcanologist’s job important?
Volcanologists study volcanoes so that they can warn people when the volcano is going to erupt and so save many lives.
2) Where is Mount Kilauea?
Mount Kilauea is in Hawaii.
3) Why is the lava that flows on Mount Kilauea more dangerous than the actual eruption?
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.
4) What caused the writer’s bedroom to become as bright as day even though it was night?
The light was caused by the red-hot rocks and gas that erupted from the volcano.
5) Why did the scientists have to get close to the volcano after it began erupting?
The scientists needed to get samples of the lava so they could study them.6) Why was it difficult for the writer to walk towards the edge of the crater?
The author was wearing special protective clothing that made it difficult to walk.
7) What does the writer find impressive about volcanoes even after studying them for 20 years?
The author is impressed by the beauty of the eruption and also by its potential to cause great destruction.
3. The main idea of the passage:
Part 1(Pa 1-2)
Part 2(Pa 3-4)
Part 3(Pa 5)
What is the writer’s job and the
importance of his job?
The writer’s experience of
watching the volcano eruption.
The reasons why the writer is
enthusiastic about his job?1. Watch the video episode of John’s getting close to the crater. Guess what John think of his job as a volcanologist.
Knowing when and where an eruption will occur is one of the great challenges for a volcanologist Volcanoes provide the world's most beautiful and powerful natural events. Nothing in nature can exceed(be more than) their beauty. Post reading2. Creative group discussion:
1） Having learnt a little more about the work of a volcanologist, do you think it is an occupation you would enjoy? Discuss your reasons with others in your class.
2) If you could meet the writer of the passage, what kind of questions would you ask? Discuss with others in
your class. Assignment (Homework) Find out words, expressions and sentences which you think are useful, important or difficult to understand.
Finish exercises in Learning about language.(Ex 1, 2)Goodbye
