work of a volcanologist, do you think it is an occupation you would enjoy? Give your reasons.2. In pairs discuss what skills you think a
volcanologist should have. Make a list.No, I probably wouldn’t enjoy this job

dangerous situations. Also, I’m not very
good at science.Suggested answers: 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.or 3. Look at these three people who would like to study volcanoes. Which one would you choose to become a volcanologist? Give your reasons.Fred Spears:He has the interest but not the qualifications. So he is not
a good choice to become a volcanologist.Susan Kelp:She has studied geology and has an interest in volcanoes.
She has all the necessary
qualifications but she does not have practical
experience devising experiments and
analyzing data.Charles:He is a medical doctor with an interest in
volcanoes. He has experience of conducting
experiments but does not have the specific
qualifications needed to become a
volcanologist.I would choose Susan Kelp because she has
the necessary qualifications and the interest.
Although she has not yet conducted
experiments she will either have learned the
techniques during university course or be able
to learn them on-the-job. She seems to be the
most suitable candidate.So Spend some time researching the Ya’an earthquake in Sichuan. You can use books, magazines, newspapers or the Internet. Collect pictures or diagrams and look for information about: what causes this earthquake

We were driving back to my hometown for Spring Festival and it was a very long journey. I was nearly asleep in the back of the car when my father shouted that the road was becoming quite slippery with snow. Suddenly we slid across the road and stopped. At first I only felt a little nervous. After all, the car was warm and my parents were there but there was a long line of cars ahead of us and none of them were moving. Then I did begin to feel bothered and concerned. My father got out and went to investigate. He returned to say that we would not be able to continue our journey until the road was cleared. Soon we were told that the army was bringing salt and sand to make the road safe again. We waited in the car. It got colder and colder. I began to tremble even though I had a blanket round me. What if the army could not clear the road! I began to panic. Just when I felt that I could not stand the situation any more, I heard a shout. The army had arrived, the road was being cleared and we were saved. I felt so relieved and happy that my family’s suffering was over!SPEAKING TASK ON PAGE 73 Reading on page 39Using languageReading and writingFind out a key word for each Para.storiesTianchicoinChang
