Teaching Procedures
十月革命Step I Greetings and Revision
Greet the whole class as usual.
T: Have you finished your homework?

Step II Warming up
T: Plea open your books at Page 73.Look at the four pictures. What can you e in the pictures? Have a discussion with your partner and do the exercis. Some minutes later, I'll ask some of you to give the answers.
(Teacher goes among the class and join in the students' discussion. Some minutes later, teacher says the following. )
T: Have you finished?
Ss: Yes.
上海底薪T: Let's do Ex. 1. Who will talk about the first picture?
S: Perhaps the first picture is a geomorphologic map.
T: Plea go on !
SB: In the cond picture we can e a scene in which some tall trees are blown down. Perhaps a typhoon has just happened. What a sad scene! If we want to get more information, we can e pictures taken by the satellite on the Internet.
Sc: In the third picture. I saw a comet. It has a very bright head and a long less
bright tail and is moving through the sky to the ground. If we want to e it
more clearly, we can e it through a telescope.
T: How do you know when it will happen?
SD: The TV programme will tell us in advance. It will tell us its detailed timetable and the other information about it.
SE: In the last picture we can e a cell, but it is enlarged many times. We often e cells in our biology class. As long as you have a microscope, you can e them clearly.
T: Do you often hear about the things in newspapers or on TV?
SF: Both. In summer we often hear about typhoons on the Pacific. There are about ven typhoons in the southeast of our country. If there are fewer, drought will take place.
SG: Some years ago, we learned from the newspaper and TV that a comet would pass through the dark sky in our country. Our geography teacher organized us to watch it through a microscope.
T: Now answer the third question, plea. How does nature form a danger to people in the world and how can science help reduce that threat?
SH: Typhoons are harmful to us. They can pull up the tall tree, blow down the wire poles and even destroy people's hous. Sometimes it can cau vere flood.
SI: Earthquake can bring great damage to people's life. It can cut off electricity

and water supply and destroy hous. Even it often caus deaths. In 1976 a terrible earthquake in Tang Shan killed thousands of people.
SJ: If the typhoon and earthquake can be forecast, damages will greatly be reduced. Scientists in our country can forecast typhoons exactly and some of the earthquakes have been forecast before. I’m sure they will control the natural disaster and reduce the loss to the lowest degree.
T: In which ways are the fields of science important to our everyday life?
SK: Geograph is important. If we do well in it, we can find more coal, gas and oil, as well as all kinds of metal.
SL: Meteorology is important. If we master it, we can tell our farmers much information about farming. If so, they will increa their productivity and
