　　THE FIRST PERIOD READING
　　Step I.  Revision
　　Check the homework with the whole class.
　　Step II. Warming up
　　Ask the students to read the instructions and mare they know what to do, and then have a discussion about the two pictures.
　　T: Today, before we begin our reading, I’d like to as a question, “What is the biggest sound you have heard in your life?”
　　S1: The sound of wind that blew in a winter night when I was very young. It sounded like a ghost who was howling. I was very frightened at that time.
　　S2: The biggest noise was the one that I heard when my neighbor was quarrelling with his wife. Perhaps, they broke their TV set.

　　S1: Tangshan is a beautiful city. It has beautiful gardens, broad roads and some tall buildings.
　　S2: From the picture of San Francisco, I can see that it is a very big city.  There are many tall buildings thickly standing on the earth. I think the population of the city is very large.
　　T: Good! What will happen if there has been a big earthquake in these two cities? Work in pairs and discuss it. Then I’ll ask so me of you to show your opinion.
　　Step III.  Pre-reading
　　There are two questions in this part. Both are very interesting. The first one can more or less reveal the students’ values; while the second one can enlarge their imagination. No matter what their answers are,
