9、rthquakes and the ways of reducing losses from earthquakes.LISTENING TEXTWhy do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates. At San Francisco, the Pacific plate which is moving towards the northwest meets the North American plate. The

10、Pacific plate is moving very slowlyat 5. 3 centimeters a year. Sometimes these two plates stop and do not move for years. Then suddenly, they jump and an earthquake is felt. As a result of the movement of these plates, California has always had a lot of earthquakes. When the 1906 earthquake happened

11、, the Pacific plate jumped 5-6 meters to the north.China also has an unlucky place on the earth. The Pacific plate is also pushing on China from the east as the plate moves west. Likewise, the Indian plate is pushing on China from the southwest as that plate moves northeast. The same power that prod

12、uced the great Himalayan Mountains now causes earthquakes in China.We cannot stop earthquakes, but we can do things to make sure they do not destroy whole cities. First, it is not a good idea to build houses along the lines where two of the earths plates join together. Second, if you think there may

13、 be an earthquake, it is better to build houses on rock than on sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up.Step 4 Listening task(on Page 66 in the Workbook)Turn to Page 66. Look at the pictures and discuss

14、what the might have learned.1. In four let the students discuss what would be the best way to protect oneself if there was an earthquake.2. Ask one member of the group to give their ideas to the class.3. Let the class evaluate each groups idea and see if they agree. If they do, write the idea on the

15、 board. Collect the ideas all the groups have contributed.4. Ask the students to choose the three that they think are the most useful if an earthquake comes.5. Listen to the tape for the first time and see if the ideas on the tape are the same. Discuss why the plans on the tape are different from th

16、e ones suggested by the class.6. Now make the earthquake plan. Then listen to the tape for the second time to improve the earthquake plan.My Earthquake Plan1st thing I must do:I must drop to the floor and cover my head and neck with my arms.2nd thing I must do:Make sure I hide under something like a

17、 table to protect myself from things falling on top of me.3rd thing I must do:I must hold onto the furniture so it doesnt move away from me during the earthquake.7. Listen to the tape a third time and then write down any other advice that you think is useful.My Earthquake AdviceIf you are outside, y

18、ou should keep away from power lines, trees, signs, cars and buildings.If you are in the living room, you should make sure that the bookcases are fastened to the wall and the TV set is tied to a table so that they cant move.If you are in the house alone, you should ring a family friend to tell them

19、where you are and collect your personal earthquake bag.8. Read the listening text and make it more clear what to do during an earthquake.Step 5 Listening(on Page 31 in Using language)1.
