What is the volcanologist wearing when getting close to the crater?He is wearing white protective suits that covered his whole body, helmets, big boots and special gloves, just like a spaceman.1) Why is a volcanologist’s job important?
2) Where is Mount Kilauea?
3) Why is the lava that flows on Mount Kilauea more dangerous than the actual eruption?
4) What caused the writer’s bedroom to become as bright as day even though it was night?Scanning1. Scan the passage and answer the following questions:5) Why did the scientists have to get close to the volcano after it began erupting?
6) Why was it difficult for the writer to walk towards the edge of the crater?
7) What does the writer find impressive about volcanoes even after studying them for 20 years?
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.
Catastrophic eruption of Mount Vesuvius on August 24 of 79 A.D. buried the towns of Herculaneum and Pompeii in Italy. Mount Vesuvius
?This mountain has erupted more than 50 times since the eruption in 79 A.D., when it buried Pompeii and its sister city, Herculaneum.
?After Pompeii was buried and lost to history, the volcano continued to erupt every 100 years until about 1037 A.D., when it entered a 600-year period of quiescence.
?In 1631, the volcano killed an additional 4000 unsuspecting inhabitants. ? Mount Kilauea
It is Hawaii's youngest and yet most active volcano. It first erupted in January 1983 and has been active ever since.
In the past 245 years there have been 62 eruptions... That's about an eruption every four years.
Mt. Kilauea is a shield volcano-the largest types of volcanoes in the world and have fluid lava and are basically, just broad slopes.
An extinct volcanoHaleakala Crater, the largest dormant volcano in the world
Maui, Hawaii
An active volcano3. 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
