Step 3 Skimming
Skim the text and answer the following questions.
1．What is the writer?
He is a volcanologist working for the Hawaiian Volcano Observatory. He mainly collects information about Mount Kilauea.
2．When did he first see an eruption? How did it look like?
It was in the second week after he arrived in Hawaii. It was very bright although it was night. Red lava fountained hundreds of meters into the air and it was a fantastic sight.
3. What was he wearing when getting close to the crater? And what was the result?
He was wearing white protective suits that covered his whole body, helmets, big boots and special gloves, just like a spaceman. As a result, it made him difficult to walk.
Step 4 Scanning
Scan the text 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. 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.
3. 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.
4. 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.
