Warming up (1) Warming up by talking Good morning, class. I think you must know Mr. Nature, and he is emotional. When he is happy, we will have a fine weather, so can you describe these views? But he is emotional, when he gets angry, what will happen? Do you know how many kinds of natural disasters? What are they? Look at the pictures, can you name all the disasters? Have you ever experienced an earthquake? Can you describe how terrible an earthquake is? (The earth is shaking; all the buildings will fall down; many people will die; many children will become orphans.) (2) Warming up by discussing Now, look at the pictures of Tangshan and San Francisco in warming up and describe what you see in the pictures. (beautiful cities; broad roads; tall building; large population.) What will happen if there has been a big earthquake in these two cities? As we all know, earthquakes are disasters to everyone. But can we avoid or at least reduce the loss caused by earthquakes? Can we foretell earthquakes? Now lets come to Pre-reading and decide what may happen before an earthquake comes.II. Pre-reading by talking and sharing(1) Enjoy a part of film of earthquake A) What other disasters does it have? (flood/drought/earthquake/fire/typhoon/disease and so on) B) Which disaster may cause the worst damage? (earthquake) (2) Ask some questionsA) Have you ever heard a story of an earthquake? (show video of Tangshan and San Francisco earthquake) B) Have you experienced an earthquake? If you have, tell me your experience. If no, just imagine what will happen before an earthquake? C) The earthquake is coming, if youre trapped in the earthquake, how will you feel? What will you do? Will you leave right away? If you have time to take only one thing, what will you take, why? D) What kind of damage can an earthquake cause? (buildings are destroyed; people are killed; families are broken) III.
